There are a couple of small problems when compiling MySQL on HP-UX. We recommend that you use gcc instead of the HP-UX native compiler, because gcc produces better code.

We recommend using gcc 2.95 on HP-UX. Don't use high optimization flags (such as -O6) because they may not be safe on HP-UX.

The following configure line should work with gcc 2.95:

CFLAGS="-I/opt/dce/include -fpic" \
CXXFLAGS="-I/opt/dce/include -felide-constructors -fno-exceptions \
-fno-rtti" \
CXX=gcc \
./configure --with-pthread \
    --with-named-thread-libs='-ldce' \
    --prefix=/usr/local/mysql --disable-shared

The following configure line should work with gcc 3.1:

CFLAGS="-DHPUX -I/opt/dce/include -O3 -fPIC" CXX=gcc \
CXXFLAGS="-DHPUX -I/opt/dce/include -felide-constructors \
    -fno-exceptions -fno-rtti -O3 -fPIC" \
./configure --prefix=/usr/local/mysql \
    --with-extra-charsets=complex --enable-thread-safe-client \
    --enable-local-infile  --with-pthread \
    --with-named-thread-libs=-ldce --with-lib-ccflags=-fPIC
    --disable-shared

Because of some critical bugs in the standard HP-UX libraries, you should install the following patches before trying to run MySQL on HP-UX 11.0:

PHKL_22840 Streams cumulative
PHNE_22397 ARPA cumulative

This solves the problem of getting EWOULDBLOCK from recv() and EBADF from accept() in threaded applications.

If you are using gcc 2.95.1 on an unpatched HP-UX 11.x system, you may get the following error:

In file included from /usr/include/unistd.h:11,
                 from ../include/global.h:125,
                 from mysql_priv.h:15,
                 from item.cc:19:
/usr/include/sys/unistd.h:184: declaration of C function ...
/usr/include/sys/pthread.h:440: previous declaration ...
In file included from item.h:306,
                 from mysql_priv.h:158,
                 from item.cc:19:

The problem is that HP-UX does not define pthreads_atfork() consistently. It has conflicting prototypes in /usr/include/sys/unistd.h:184 and /usr/include/sys/pthread.h:440.

One solution is to copy /usr/include/sys/unistd.h into mysql/include and edit unistd.h and change it to match the definition in pthread.h. Look for this line:

extern int pthread_atfork(void (*prepare)(), void (*parent)(),
                                          void (*child)());

Change it to look like this:

extern int pthread_atfork(void (*prepare)(void), void (*parent)(void),
                                          void (*child)(void));

After making the change, the following configure line should work:

CFLAGS="-fomit-frame-pointer -O3 -fpic" CXX=gcc \
CXXFLAGS="-felide-constructors -fno-exceptions -fno-rtti -O3" \
./configure --prefix=/usr/local/mysql --disable-shared

If you are using HP-UX compiler, you can use the following command (which has been tested with cc B.11.11.04):

CC=cc CXX=aCC CFLAGS=+DD64 CXXFLAGS=+DD64 ./configure \
    --with-extra-character-set=complex

You can ignore any errors of the following type:

aCC: warning 901: unknown option: `-3': use +help for online
documentation

If you get the following error from configure, verify that you don't have the path to the K&R compiler before the path to the HP-UX C and C++ compiler:

checking for cc option to accept ANSI C... no
configure: error: MySQL requires an ANSI C compiler (and a C++ compiler).
Try gcc. See the Installation chapter in the Reference Manual.

Another reason for not being able to compile is that you didn't define the +DD64 flags as just described.

Another possibility for HP-UX 11 is to use the MySQL binaries provided at http://dev.mysql.com/downloads/, which we have built and tested ourselves. We have also received reports that the HP-UX 10.20 binaries supplied by MySQL can be run successfully on HP-UX 11. If you encounter problems, you should be sure to check your HP-UX patch level.

Automatic detection of xlC is missing from Autoconf, so a number of variables need to be set before running configure. The following example uses the IBM compiler:

export CC="xlc_r -ma -O3 -qstrict -qoptimize=3 -qmaxmem=8192 "
export CXX="xlC_r -ma -O3 -qstrict -qoptimize=3 -qmaxmem=8192"
export CFLAGS="-I /usr/local/include"
export LDFLAGS="-L /usr/local/lib"
export CPPFLAGS=$CFLAGS
export CXXFLAGS=$CFLAGS

./configure --prefix=/usr/local \
                --localstatedir=/var/mysql \
                --sbindir='/usr/local/bin' \
                --libexecdir='/usr/local/bin' \
                --enable-thread-safe-client \
                --enable-large-files

The preceding options are used to compile the MySQL distribution that can be found at http://www-frec.bull.com/.

If you change the -O3 to -O2 in the preceding configure line, you must also remove the -qstrict option. This is a limitation in the IBM C compiler.

If you are using gcc to compile MySQL, you must use the -fno-exceptions flag, because the exception handling in gcc is not thread-safe! There are also some known problems with IBM's assembler that may cause it to generate bad code when used with gcc.

We recommend the following configure line with gcc 2.95 on AIX:

CC="gcc -pipe -mcpu=power -Wa,-many" \
CXX="gcc -pipe -mcpu=power -Wa,-many" \
CXXFLAGS="-felide-constructors -fno-exceptions -fno-rtti" \
./configure --prefix=/usr/local/mysql --with-low-memory

The -Wa,-many option is necessary for the compile to be successful. IBM is aware of this problem but is in no hurry to fix it because of the workaround that is available. We don't know if the -fno-exceptions is required with gcc 2.95, but because MySQL doesn't use exceptions and the option generates faster code, we recommend that you should always use it with gcc.

If you get a problem with assembler code, try changing the -mcpu=xxx option to match your CPU. Typically power2, power, or powerpc may need to be used. Alternatively, you might need to use 604 or 604e. We are not positive but suspect that power would likely be safe most of the time, even on a power2 machine.

If you don't know what your CPU is, execute a uname -m command. It produces a string that looks like 000514676700, with a format of xxyyyyyymmss where xx and ss are always 00, yyyyyy is a unique system ID and mm is the ID of the CPU Planar. A chart of these values can be found at http://www16.boulder.ibm.com/pseries/en_US/cmds/aixcmds5/uname.htm.

This gives you a machine type and a machine model you can use to determine what type of CPU you have.

If you have problems with signals (MySQL dies unexpectedly under high load), you may have found an OS bug with threads and signals. In this case, you can tell MySQL not to use signals by configuring as follows:

CFLAGS=-DDONT_USE_THR_ALARM CXX=gcc \
CXXFLAGS="-felide-constructors -fno-exceptions -fno-rtti \
-DDONT_USE_THR_ALARM" \
./configure --prefix=/usr/local/mysql --with-debug \
    --with-low-memory

This doesn't affect the performance of MySQL, but has the side effect that you can't kill clients that are “sleeping” on a connection with mysqladmin kill or mysqladmin shutdown. Instead, the client dies when it issues its next command.

On some versions of AIX, linking with libbind.a makes getservbyname() dump core. This is an AIX bug and should be reported to IBM.

For AIX 4.2.1 and gcc, you have to make the following changes.

After configuring, edit config.h and include/my_config.h and change the line that says this:

#define HAVE_SNPRINTF 1

to this:

#undef HAVE_SNPRINTF

And finally, in mysqld.cc, you need to add a prototype for initgroups().

#ifdef _AIX41
extern "C" int initgroups(const char *,int);
#endif

For 32-bit binaries, if you need to allocate a lot of memory to the mysqld process, it's not enough to just use ulimit -d unlimited. You may also have to modify mysqld_safe to add a line something like this:

export LDR_CNTRL='MAXDATA=0x80000000'

You can find more information about using a lot of memory at http://publib16.boulder.ibm.com/pseries/en_US/aixprggd/genprogc/lrg_prg_support.htm.

Users of AIX 4.3 should use gmake instead of the make utility included with AIX.

As of AIX 4.1, the C compiler has been unbundled from AIX as a separate product. We recommend using gcc 3.3.2, which can be obtained here: ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc/gcc/

The steps for compiling MySQL on AIX with gcc 3.3.2 are similar to those for using gcc 2.95 (in particular, the need to edit config.h and my_config.h after running configure). However, before running configure, you should also patch the curses.h file as follows:

/opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.2.0.0/3.3.2/include/curses.h.ORIG
       Mon Dec 26 02:17:28 2005

On SunOS 4, MIT-pthreads is needed to compile MySQL. This in turn means you need GNU make.

Some SunOS 4 systems have problems with dynamic libraries and libtool. You can use the following configure line to avoid this problem:

./configure --disable-shared --with-mysqld-ldflags=-all-static

When compiling readline, you may get warnings about duplicate defines. These can be ignored.

When compiling mysqld, there are some implicit declaration of function warnings. These can be ignored.

This section does not apply to MySQL Enterprise Server users.

If you are using egcs 1.1.2 on Digital Unix, you should upgrade to gcc 2.95.2, because egcs on DEC has some serious bugs!

When compiling threaded programs under Digital Unix, the documentation recommends using the -pthread option for cc and cxx and the -lmach -lexc libraries (in addition to -lpthread). You should run configure something like this:

CC="cc -pthread" CXX="cxx -pthread -O" \
./configure --with-named-thread-libs="-lpthread -lmach -lexc -lc"

When compiling mysqld, you may see a couple of warnings like this:

mysqld.cc: In function void handle_connections()':
mysqld.cc:626: passing long unsigned int *' as argument 3 of
accept(int,sockadddr *, int *)'

You can safely ignore these warnings. They occur because configure can detect only errors, not warnings.

If you start the server directly from the command line, you may have problems with it dying when you log out. (When you log out, your outstanding processes receive a SIGHUP signal.) If so, try starting the server like this:

nohup mysqld [options] &

nohup causes the command following it to ignore any SIGHUP signal sent from the terminal. Alternatively, start the server by running mysqld_safe, which invokes mysqld using nohup for you. See Section 4.3.2, “mysqld_safe — MySQL Server Startup Script”.

If you get a problem when compiling mysys/get_opt.c, just remove the #define _NO_PROTO line from the start of that file.

If you are using Compaq's CC compiler, the following configure line should work:

CC="cc -pthread"
CFLAGS="-O4 -ansi_alias -ansi_args -fast -inline speed \
        -speculate all -arch host"
CXX="cxx -pthread"
CXXFLAGS="-O4 -ansi_alias -ansi_args -fast -inline speed \
          -speculate all -arch host -noexceptions -nortti"
export CC CFLAGS CXX CXXFLAGS
./configure \
    --prefix=/usr/local/mysql \
    --with-low-memory \
    --enable-large-files \
    --enable-shared=yes \
    --with-named-thread-libs="-lpthread -lmach -lexc -lc"
gnumake

If you get a problem with libtool when compiling with shared libraries as just shown, when linking mysql, you should be able to get around this by issuing these commands:

cd mysql
/bin/sh ../libtool --mode=link cxx -pthread  -O3 -DDBUG_OFF \
    -O4 -ansi_alias -ansi_args -fast -inline speed \
    -speculate all \ -arch host  -DUNDEF_HAVE_GETHOSTBYNAME_R \
    -o mysql  mysql.o readline.o sql_string.o completion_hash.o \
    ../readline/libreadline.a -lcurses \
    ../libmysql/.libs/libmysqlclient.so  -lm
cd ..
gnumake
gnumake install
scripts/mysql_install_db

If you have problems compiling and have DEC CC and gcc installed, try running configure like this:

CC=cc CFLAGS=-O CXX=gcc CXXFLAGS=-O3 \
./configure --prefix=/usr/local/mysql

If you get problems with the c_asm.h file, you can create and use a 'dummy' c_asm.h file with:

touch include/c_asm.h
CC=gcc CFLAGS=-I./include \
CXX=gcc CXXFLAGS=-O3 \
./configure --prefix=/usr/local/mysql

Note that the following problems with the ld program can be fixed by downloading the latest DEC (Compaq) patch kit from: http://ftp.support.compaq.com/public/unix/.

On OSF/1 V4.0D and compiler "DEC C V5.6-071 on Digital Unix V4.0 (Rev. 878)," the compiler had some strange behavior (undefined asm symbols). /bin/ld also appears to be broken (problems with _exit undefined errors occurring while linking mysqld). On this system, we have managed to compile MySQL with the following configure line, after replacing /bin/ld with the version from OSF 4.0C:

CC=gcc CXX=gcc CXXFLAGS=-O3 ./configure --prefix=/usr/local/mysql

With the Digital compiler "C++ V6.1-029," the following should work:

CC=cc -pthread
CFLAGS=-O4 -ansi_alias -ansi_args -fast -inline speed \
       -speculate all -arch host
CXX=cxx -pthread
CXXFLAGS=-O4 -ansi_alias -ansi_args -fast -inline speed \
         -speculate all -arch host -noexceptions -nortti
export CC CFLAGS CXX CXXFLAGS
./configure --prefix=/usr/mysql/mysql \
            --with-mysqld-ldflags=-all-static --disable-shared \
            --with-named-thread-libs="-lmach -lexc -lc"

In some versions of OSF/1, the alloca() function is broken. Fix this by removing the line in config.h that defines 'HAVE_ALLOCA'.

The alloca() function also may have an incorrect prototype in /usr/include/alloca.h. This warning resulting from this can be ignored.

configure uses the following thread libraries automatically: --with-named-thread-libs="-lpthread -lmach -lexc -lc".

When using gcc, you can also try running configure like this:

CFLAGS=-D_PTHREAD_USE_D4 CXX=gcc CXXFLAGS=-O3 ./configure ...

If you have problems with signals (MySQL dies unexpectedly under high load), you may have found an OS bug with threads and signals. In this case, you can tell MySQL not to use signals by configuring with:

CFLAGS=-DDONT_USE_THR_ALARM \
CXXFLAGS=-DDONT_USE_THR_ALARM \
./configure ...

This does not affect the performance of MySQL, but has the side effect that you can't kill clients that are “sleeping” on a connection with mysqladmin kill or mysqladmin shutdown. Instead, the client dies when it issues its next command.

With gcc 2.95.2, you may encounter the following compile error:

sql_acl.cc:1456: Internal compiler error in `scan_region',
at except.c:2566
Please submit a full bug report.

To fix this, you should change to the sql directory and do a cut-and-paste of the last gcc line, but change -O3 to -O0 (or add -O0 immediately after gcc if you don't have any -O option on your compile line). After this is done, you can just change back to the top-level directory and run make again.

This section does not apply to MySQL Enterprise Server users.

As of MySQL 5.0, we don't provide binaries for Irix any more.

If you are using Irix 6.5.3 or newer, mysqld is able to create threads only if you run it as a user that has CAP_SCHED_MGT privileges (such as root) or give the mysqld server this privilege with the following shell command:

chcap "CAP_SCHED_MGT+epi" /opt/mysql/libexec/mysqld

You may have to undefine some symbols in config.h after running configure and before compiling.

In some Irix implementations, the alloca() function is broken. If the mysqld server dies on some SELECT statements, remove the lines from config.h that define HAVE_ALLOC and HAVE_ALLOCA_H. If mysqladmin create doesn't work, remove the line from config.h that defines HAVE_READDIR_R. You may have to remove the HAVE_TERM_H line as well.

SGI recommends that you install all the patches on this page as a set: http://support.sgi.com/surfzone/patches/patchset/6.2_indigo.rps.html

At the very minimum, you should install the latest kernel rollup, the latest rld rollup, and the latest libc rollup.

You definitely need all the POSIX patches on this page, for pthreads support:

http://support.sgi.com/surfzone/patches/patchset/6.2_posix.rps.html

If you get the something like the following error when compiling mysql.cc:

"/usr/include/curses.h", line 82: error(1084):
invalid combination of type

Type the following in the top-level directory of your MySQL source tree:

extra/replace bool curses_bool < /usr/include/curses.h > include/curses.h
make

There have also been reports of scheduling problems. If only one thread is running, performance is slow. Avoid this by starting another client. This may lead to a two-to-tenfold increase in execution speed thereafter for the other thread. This is a poorly understood problem with Irix threads; you may have to improvise to find solutions until this can be fixed.

If you are compiling with gcc, you can use the following configure command:

CC=gcc CXX=gcc CXXFLAGS=-O3 \
./configure --prefix=/usr/local/mysql --enable-thread-safe-client \
    --with-named-thread-libs=-lpthread

On Irix 6.5.11 with native Irix C and C++ compilers ver. 7.3.1.2, the following is reported to work

CC=cc CXX=CC CFLAGS='-O3 -n32 -TARG:platform=IP22 -I/usr/local/include \
-L/usr/local/lib' CXXFLAGS='-O3 -n32 -TARG:platform=IP22 \
-I/usr/local/include -L/usr/local/lib' \
./configure --prefix=/usr/local/mysql --with-innodb --with-berkeley-db \
    --with-libwrap=/usr/local \
    --with-named-curses-libs=/usr/local/lib/libncurses.a

The current port is tested only on sco3.2v5.0.5, sco3.2v5.0.6, and sco3.2v5.0.7 systems. There has also been progress on a port to sco3.2v4.2. Open Server 5.0.8 (Legend) has native threads and allows files greater than 2GB. The current maximum file size is 2GB.

We have been able to compile MySQL with the following configure command on OpenServer with gcc 2.95.3.

CC=gcc CFLAGS="-D_FILE_OFFSET_BITS=64 -O3" \
CXX=gcc CXXFLAGS="-D_FILE_OFFSET_BITS=64 -O3" \
./configure --prefix=/usr/local/mysql \
    --enable-thread-safe-client --with-innodb \
    --with-openssl --with-vio --with-extra-charsets=complex

gcc is available at ftp://ftp.sco.com/pub/openserver5/opensrc/gnutools-5.0.7Kj.

This development system requires the OpenServer Execution Environment Supplement oss646B on OpenServer 5.0.6 and oss656B and The OpenSource libraries found in gwxlibs. All OpenSource tools are in the opensrc directory. They are available at ftp://ftp.sco.com/pub/openserver5/opensrc/.

We recommend using the latest production release of MySQL.

SCO provides operating system patches at ftp://ftp.sco.com/pub/openserver5 for OpenServer 5.0.[0-6] and ftp://ftp.sco.com/pub/openserverv5/507 for OpenServer 5.0.7.

SCO provides information about security fixes at ftp://ftp.sco.com/pub/security/OpenServer for OpenServer 5.0.x.

The maximum file size on an OpenSever 5.0.x system is 2GB.

The total memory which can be allocated for streams buffers, clists, and lock records cannot exceed 60MB on OpenServer 5.0.x.

Streams buffers are allocated in units of 4096 byte pages, clists are 70 bytes each, and lock records are 64 bytes each, so:

(NSTRPAGES × 4096) + (NCLIST × 70) + (MAX_FLCKREC × 64) <= 62914560

Follow this procedure to configure the Database Services option. If you are unsure whether an application requires this, see the documentation provided with the application.

After you complete this process, reboot the system to create a new kernel incorporating these changes.

We recommend setting these values as follows:

To make changes to the kernel, use the idtune name parameter command. idtune modifies the /etc/conf/cf.d/stune file for you. For example, to change SEMMS to 200, execute this command as root:

# /etc/conf/bin/idtune SEMMNS 200

Then rebuild and reboot the kernel by issuing this command:

# /etc/conf/bin/idbuild -B && init 6

We recommend tuning the system, but the proper parameter values to use depend on the number of users accessing the application or database and size the of the database (that is, the used buffer pool). The following kernel parameters can be set with idtune:

You need to at least install the SCO OpenServer Linker and Application Development Libraries or the OpenServer Development System to use gcc. You cannot use the GCC Dev system without installing one of these.

You should get the FSU Pthreads package and install it first. This can be found at http://moss.csc.ncsu.edu/~mueller/ftp/pub/PART/pthreads.tar.gz. You can also get a precompiled package from ftp://ftp.zenez.com/pub/zenez/prgms/FSU-threads-3.14.tar.gz.

FSU Pthreads can be compiled with SCO Unix 4.2 with tcpip, or using OpenServer 3.0 or Open Desktop 3.0 (OS 3.0 ODT 3.0) with the SCO Development System installed using a good port of GCC 2.5.x. For ODT or OS 3.0, you need a good port of GCC 2.5.x. There are a lot of problems without a good port. The port for this product requires the SCO Unix Development system. Without it, you are missing the libraries and the linker that is needed. You also need SCO-3.2v4.2-includes.tar.gz. This file contains the changes to the SCO Development include files that are needed to get MySQL to build. You need to replace the existing system include files with these modified header files. They can be obtained from ftp://ftp.zenez.com/pub/zenez/prgms/SCO-3.2v4.2-includes.tar.gz.

To build FSU Pthreads on your system, all you should need to do is run GNU make. The Makefile in FSU-threads-3.14.tar.gz is set up to make FSU-threads.

You can run ./configure in the threads/src directory and select the SCO OpenServer option. This command copies Makefile.SCO5 to Makefile. Then run make.

To install in the default /usr/include directory, log in as root, and then cd to the thread/src directory and run make install.

Remember that you must use GNU make to build MySQL.

With SCO 3.2V4.2, you should use FSU Pthreads version 3.14 or newer. The following configure command should work:

CFLAGS="-D_XOPEN_XPG4" CXX=gcc CXXFLAGS="-D_XOPEN_XPG4" \
./configure \
    --prefix=/usr/local/mysql \
    --with-named-thread-libs="-lgthreads -lsocket -lgen -lgthreads" \
    --with-named-curses-libs="-lcurses"

You may have problems with some include files. In this case, you can find new SCO-specific include files at ftp://ftp.zenez.com/pub/zenez/prgms/SCO-3.2v4.2-includes.tar.gz.

You should unpack this file in the include directory of your MySQL source tree.

SCO development notes:

Beginning with Legend/OpenServer 6.0.0, there are native threads and no 2GB file size limit.

OpenServer 6 includes these key improvements:

OpenServer 6.0.0 commands are organized as follows:

The following is a guide to setting PATH on OpenServer 6. If the user wants the traditional OpenServer 5.0.x then PATH should be /bin first. If the user wants LFS support, the path should be /u95/bin:/bin. If the user wants UnixWare 7 support first, the path would be /udk/bin:/u95/bin:/bin:.

We recommend using the latest production release of MySQL. Should you choose to use an older release of MySQL on OpenServer 6.0.x, you must use a version of MySQL at least as recent as 3.22.13 to get fixes for some portability and OS problems.

MySQL distribution files with names of the following form are tar archives of media are tar archives of media images suitable for installation with the SCO Software Manager (/etc/custom) on SCO OpenServer 6:

mysql-PRODUCT-5.0.68-sco-osr6-i686.VOLS.tar

A distribution where PRODUCT is pro-cert is the Commercially licensed MySQL Pro Certified server. A distribution where PRODUCT is pro-gpl-cert is the MySQL Pro Certified server licensed under the terms of the General Public License (GPL).

Select whichever distribution you wish to install and, after download, extract the tar archive into an empty directory. For example:

shell> mkdir /tmp/mysql-pro
shell> cd /tmp/mysql-pro
shell> tar xf /tmp/mysql-pro-cert-5.0.68-sco-osr6-i686.VOLS.tar

Prior to installation, back up your data in accordance with the procedures outlined in Section 2.4.17, “Upgrading MySQL”.

Remove any previously installed pkgadd version of MySQL:

shell> pkginfo mysql 2>&1 > /dev/null && pkgrm mysql

Install MySQL Pro from media images using the SCO Software Manager:

shell> /etc/custom -p SCO:MySQL -i -z /tmp/mysql-pro

Alternatively, the SCO Software Manager can be displayed graphically by clicking on the Software Manager icon on the desktop, selecting Software -> Install New, selecting the host, selecting Media Images for the Media Device, and entering /tmp/mysql-pro as the Image Directory.

After installation, run mkdev mysql as the root user to configure your newly installed MySQL Pro Certified server.

If you wish to configure your MySQL Pro server to interface with the Apache Web server via PHP, download and install the PHP update from SCO at ftp://ftp.sco.com/pub/updates/OpenServer/SCOSA-2006.17/.

We have been able to compile MySQL with the following configure command on OpenServer 6.0.x:

CC=cc CFLAGS="-D_FILE_OFFSET_BITS=64 -O3" \
CXX=CC CXXFLAGS="-D_FILE_OFFSET_BITS=64 -O3" \
./configure --prefix=/usr/local/mysql \
    --enable-thread-safe-client --with-berkeley-db \
    --with-extra-charsets=complex \
    --build=i686-unknown-sysv5SCO_SV6.0.0

If you use gcc, you must use gcc 2.95.3 or newer.

CC=gcc CXX=g++ ... ./configure ...

The version of Berkeley DB that comes with either UnixWare 7.1.4 or OpenServer 6.0.0 is not used when building MySQL. MySQL instead uses its own version of Berkeley DB. The configure command needs to build both a static and a dynamic library in src_directory/bdb/build_unix/, but it does not with MySQL's own BDB version. The workaround is as follows.

This allows both the shared and dynamic libraries to be made and work.

SCO provides OpenServer 6 operating system patches at ftp://ftp.sco.com/pub/openserver6.

SCO provides information about security fixes at ftp://ftp.sco.com/pub/security/OpenServer.

By default, the maximum file size on a OpenServer 6.0.0 system is 1TB. Some operating system utilities have a limitation of 2GB. The maximum possible file size on UnixWare 7 is 1TB with VXFS or HTFS.

OpenServer 6 can be configured for large file support (file sizes greater than 2GB) by tuning the UNIX kernel.

By default, the entries in /etc/conf/cf.d/mtune are set as follows:

Value           Default         Min             Max
-----           -------         ---             ---
SVMMLIM         0x9000000       0x1000000       0x7FFFFFFF
HVMMLIM         0x9000000       0x1000000       0x7FFFFFFF

To make changes to the kernel, use the idtune name parameter command. idtune modifies the /etc/conf/cf.d/stune file for you. We recommend setting the kernel values by executing the following commands as root:

# /etc/conf/bin/idtune SDATLIM 0x7FFFFFFF
# /etc/conf/bin/idtune HDATLIM 0x7FFFFFFF
# /etc/conf/bin/idtune SVMMLIM 0x7FFFFFFF
# /etc/conf/bin/idtune HVMMLIM 0x7FFFFFFF
# /etc/conf/bin/idtune SFNOLIM 2048
# /etc/conf/bin/idtune HFNOLIM 2048

Then rebuild and reboot the kernel by issuing this command:

# /etc/conf/bin/idbuild -B && init 6

We recommend tuning the system, but the proper parameter values to use depend on the number of users accessing the application or database and size the of the database (that is, the used buffer pool). The following kernel parameters can be set with idtune:

We recommend using the latest production release of MySQL. Should you choose to use an older release of MySQL on UnixWare 7.1.x, you must use a version of MySQL at least as recent as 3.22.13 to get fixes for some portability and OS problems.

SCO provides operating system patches at ftp://ftp.sco.com/pub/unixware7 for UnixWare 7.1.1, ftp://ftp.sco.com/pub/unixware7/713/ for UnixWare 7.1.3, ftp://ftp.sco.com/pub/unixware7/714/ for UnixWare 7.1.4, and ftp://ftp.sco.com/pub/openunix8 for OpenUNIX 8.0.0.

SCO provides information about security fixes at ftp://ftp.sco.com/pub/security/OpenUNIX for OpenUNIX and ftp://ftp.sco.com/pub/security/UnixWare for UnixWare.

The UnixWare 7 file size limit is 1 TB with VXFS. Some OS utilities have a limitation of 2GB.

On UnixWare 7.1.4 you do not need to do anything to get large file support, but to enable large file support on prior versions of UnixWare 7.1.x, run fsadm.

# fsadm -Fvxfs -o largefiles /
# fsadm /         * Note
# ulimit unlimited
# /etc/conf/bin/idtune SFSZLIM 0x7FFFFFFF     ** Note
# /etc/conf/bin/idtune HFSZLIM 0x7FFFFFFF     ** Note
# /etc/conf/bin/idbuild -B

* This should report "largefiles".
** 0x7FFFFFFF represents infinity for these values.

Reboot the system using shutdown.

By default, the entries in /etc/conf/cf.d/mtune are set as follows:
