The Skunkware CD +is included with UnixWare 7 and current versions of OpenServer 5. + +Skunkware includes ready-to-install versions of many popular programs that +are available on the Internet. For example, gzip, gunzip, GNU make, flex, +and bison are all included. + +If you do not have this CD, the software on it +is available via anonymous ftp from ftp.sco.com/skunkware. + +For UnixWare 7.1, this CD is now labeled "Open License Software Supplement". + +Skunkware has different versions for UnixWare and +OpenServer. Make sure you install the correct version for your +operating system, except as noted below. + + +*************************************************************************** +*) GNU Make + +You need to use the GNU make program, which is on the Skunkware CD. +By default, it installs as /usr/local/bin/make. To avoid confusion +with the SCO make program, you may want to rename GNU make to gmake. + + +*************************************************************************** +*) C++ and libpq++ + +I have not been able to build libpq++, the PostgreSQL C++ interface, with +the UnixWare or OpenServer C++ compilers. By default, building PostgreSQL +also builds the libpq++ interface. When that fails, it causes the entire +build of PostgreSQL to fail. + +This is the problem if you see the following error message: + +"pgenv.cc", line 47: error: no default constructor exists for class "string" + +If you have this problem, you can disable building of libpq++ with the +following configure option: + +configure --without-CXX + + +*************************************************************************** +*) Readline + +If you install the readline library, then psql (the PostgreSQL command +line SQL interpreter) remembers each command you type, and allows +you to use arrow keys to recall and edit previous commands. This is +very helpful, and is strongly recommended. The readline library is +on the Skunkware CD. + +The readline library is not included on the UnixWare 7.1 Skunkware CD. If +you have the UnixWare 7.0.0 or 7.0.1 Skunkware CDs, you can install it +from there. Otherwise, try ftp.sco.com/skunkware. + +By default, readline installs into /usr/local/lib and /usr/local/include. +However, the PostgreSQL configure program will not find it there without +help. If you installed readline, then use the following options to configure: + +configure --with-libs=/usr/local/lib --with-includes=/usr/local/include + +Putting this together with the no-C++ option above yields: + +configure --with-libs=/usr/local/lib --with-includes=/usr/local/include --without-CXX + + +*************************************************************************** +*) Using the UDK on OpenServer + +If you are using the new Universal Development Kit (UDK) compiler on +OpenServer, you need to use different arguments to the configure program. + +First, you need to specify the "unixware" template instead of the default. + +Second, you need to specify the locations of the UDK libraries. + +Putting these together: + +configure --with-template=unixware --with-libs=/udk/usr/lib --with-includes=/udk/usr/include + +Putting these together with the no-C++ and readline options from above: + +./configure --with-template=unixware --with-libs="/udk/usr/lib /usr/local/lib" --with-includes="/udk/usr/include /usr/local/include" --without-CXX + + +*************************************************************************** +*) Shared Memory and SHMMAX + +PostgreSQL supports multiple backend daemons running at once. A block +of shared memory is used by the backend processes. A larger block +of shared memory allows PostgreSQL to run faster and support more +complicated queries. + +By default, UnixWare 7 and OpenServer are confiugured to support shared memory +blocks that are no larger than 524288 bytes, or 512K. By default, PostgreSQL +tries to allocate a shared memory block that is larger than this. If +you don't do anything, this allocation will fail, and the postmaster +daemon will not be able to run. + +The error message looks like this (the numbers may be different): + +IpcMemoryCreate: shmget failed (Invalid argument) key=5432001, size=831176, permission=600 +FATAL 1: ShmemCreate: cannot create region + +You have two choices: tell PostgreSQL to allocate a smaller shared memory +block, or tell Unix to allow larger shared memory blocks. The latter +is the preferred solution, but it requires a kernel tunable change and a +reboot to implement. + +To configure the size of the PostgreSQL shared memory block, use the -B +option to the postmaster command, which configures the number of buffers +used by PostgresSQL. (The shared memory block consists of these buffers +and around 300K of other stuff.) Each buffer uses 8K, and by default +there are 64 buffers, or 64*8*1024 = 524288 bytes (plus the ~300K of other +stuff). + +To use PostgreSQL without doing any kernel tuning, use a -B value of +about 24. This would take up 24*8*1024 = 196608 bytes, plus ~300K +of other stuff, yields about 500000, which will fit in under the +default 512K limit. + +Example: postmaster -B 24 + +The recommended option is to instead raise the kernel tunable SHMMAX, +which controls the size of the largest allowed shared memory block. + +*** Tuning SHMMAX on UnixWare *** + +To display the current value of SHMMAX, run: +/etc/conf/bin/idtune -g SHMMAX +which displays the current, default, minimum, and maximum values, in bytes. + +To set a new value for SHMMAX, run: +/etc/conf/bin/idtune SHMMAX value +where value is the new value you want to use (in bytes). + +After setting SHMMAX, rebuild the kernel and reboot. +To rebuild the kernel: +/etc/conf/bin/idbuild -B + +*** Tuning SHMMAX on OpenServer *** + +First, cd to /etc/conf/cf.d. + +To display the current value of SHMMAX, in bytes, run: +./configure -y SHMMAX + +To set a new value for SHMMAX, run: +./configure SHMMAX=value +where value is the new value you want to use (in bytes). + +After setting SHMMAX, rebuild the kernel and reboot. +To rebuild the kernel: +./link_unix + + +*************************************************************************** +*) Java and JDBC + +The JDBC interface will not build on UnixWare or OpenServer without changes. +The JDBC Makefile in src/interfaces/jdbc/Makefile uses the $$( ) construction +to run an external shell command, instead of the older ` ` syntax. +However, the $$( ) syntax does not work on UnixWare or OpenServer. +So, each of the two uses of it must be replaced with backquotes. You can +search for $$( to locate the two lines that need changing. + +In the file src/interfaces/jdbc/Makefile : + +change: + make $$($(JAVA) makeVersion) +to: + make `$(JAVA) makeVersion` + +and change: + $(JAR) -c0f $@ $$($(FIND) postgresql -name "*.class" -print) +to: + $(JAR) -c0f $@ `$(FIND) postgresql -name "*.class" -print` + +Of course, you also need to have installed Java on your system, and +make sure that /usr/java/bin is in your PATH. + +And, remember to use GNU make, as always. + + +*************************************************************************** +*) Reading the PostgreSQL man pages on UnixWare + +By default, the PostgreSQL man pages are installed into /usr/local/pgsql/man. +By default, UnixWare does not look there for man pages, so you will not +be able to read them. + +You need to make two changes to access the PostgreSQL man pages from UnixWare. + +1) You need to modify the MANPATH environment variable. I use: + +MANPATH=/usr/local/pgsql/man:/usr/dt/man:/usr/man:/usr/share/man:scohelp +export MANPATH + +2) The man pages for SQL commands are, by default, placed in section l +(normally used for "l"ocal pages). UnixWare does not support the l section. + +The solution I use is to move all these pages from section l to an unused +section, such as section 6. To accomplish that: + +cd /usr/local/pgsql/man +mv manl man6 +cd man6 +for file in *.l +do + mv $file `basename $file .l`.6 +done + +I have not tried using the PostgreSQL man pages on OpenServer.
