Oracle x86-64 on SUSE LINUX Enterprise Server 9 AMD64

This mini-HOWTO will cover the installation of oracle on SLES9 (SUSE LINUX Enterprise Server 9) for x86 and AMD64 architectures.
If you find any error imprecision or simply you have suggestions (or you need help) feel free to contact me.

Some notes before starting:

  • 9i is only available (at this moment) as for AMD64 (x86-64) so you don’t have many installation choices;
  • on this website you can find the 10g installation for 32 bit only on AMD64 because oracle haven’t yet released a version for AMD64.
  • the x86-64 architecture allow 64 and 32 bit applications to live together even if you have to follow some more step for installing and using the 32 bit part.
  • SLES9 for AMD64 can be downloaded both from novell and SuSE portals.
  • Oracle for x86-64 is available from OTN.

As always I’d like to thank the people in the suse-oracle mailing list and people on newsgroup.
I wish to thank Simon Grabinar and Joel Backer for their support on the asyncronous I/O.

I don’t wish to cover the operating system installation in this paper even because the installation is pretty easy.
I suggest you to chose the basic installation and then to add some packages later using yast.
For the filesystem I won’t open a religious war for the type and number of partitions. The test were made on reiserfs only for a wrong installation. Personally I prefer ext3 for this kind of systems (even because reading reiserfs is not supported for aio on direct I/O).
I preferred to recompile my own kernel due to problems with hugetlb, opteron architecture and numa support. You can skip this part.

After installing the basic system make sure you have the libX, libaio, compat, libaio-devel (even the 32 bit version).

Installing orarun make your installation easier so I recommend it. However read the notes below before installing.
Last version is orarun-1.8-31 and can be downloaded from suse website (actually their ftp).

Note on gcc:
gcc_old-2.95.3-11 is not necessary (as describe on some website) for installing On the contrary the linking phase _needs_ gcc 3.x!!!
So be warned: if you are going to install older gcc for anmy puprpose make sure oracle looks for the 3.x version during the relink.

Note on orarun:
Orarun is a useful package which can simplify the pre-installation part. However this rpm depends on gcc_old (read above) so if you want to use it you have two possibilities: install the old gcc and change your PATH variable for the oracle users or install it with –nodeps options.
In any case you should modify the /etc/profile.d/ deleting or commenting the lines which refer to gcc295.

Create the directory tree for the oracle installation (look at the standard OFA): the default is /opt/oracle/product/9ir2.
I prefer /u01/app/oracle/product/9ir2

linux: # mkdir -p /u01/app/oracle/product/9ir2

Make sure to change the ownership of the tree with chown (the owner should be the oracle user while the group oinstall).

linux: # chown -r oracle:oinstall /u01/app/oracle

Now you can modify some files in /etc:

  • /etc/passwd: change the shell for the oracle user created by orarun (default is /bin/false);
  • /etc/group: oracle user should belong to dba and oinstall;
  • /ets/sysconfig/oracle for ORACLE_BASE, ORACLE_HOME, ORACLE_SID and several kernel parameters plus the starting parameter for the oracle script in /etc/init.d (useful during machin boot).
  • /etc/profile.d/ (or oracle.csh depending on the shell you chose above). Make sure to set LD_ASSUME_KERNEL=’2.4.20′ (other value could be used: read Ulrich Drepper paper at then comment the lines about gcc 295 (see notes on old_gcc, below).
  • comment the following line in /etc/init.d/oracle:

Reconnect to the machine with the oracle user and check if everything is ok.

Now you can insert the CD, mount it and run the installer:

  • mount /dev/cdrom (if you didn’t insert oracle in the cdrom group then the command ahs to be issued by root).
  • if you are in a remote machine make sure your X server is running and export the DISPLAY: export DISPLAY=<your local IP>:0.0;
  • /media/cdrom/runInstaller -ignoresysprereqs

Known issues:

People referred a problem with glibc launching oraInstaller:
Unable to load native library: /tmp/OraInstall2004-02-24_10-40-59AM/jre/lib/i386/ symbol __libc_wait, version GLIBC_2.0 not defined in file with link time reference. In this case you need to install patch #3006854 from metalink which create a new library containing the definition for __libc_wait.
Maybe setting LD_ASSUME_KERNEL=’2.4.20′ helped: I didn’t need to apply the patch in either installation: 9i and 10g.

If you can’t access metalink then you can create your own patch as suggested by Jakub Jelinek (I found the trick on suse-oracle mailing list):

Try using some less buggy JVM.
Latest Sun JDK should work just fine for example.

Or, as a workaround for the buggy JVM, you can try:gcc -O2 -shared -o ~/ -fpic -xc – <<\EOF #include <errno.h> #include <sys/syscall.h> #include <sys/types.h> #include <sys/wait.h> pid_t __libc_wait (int *status) { int res; asm volatile (“pushl %%ebx\n\t” “movl %2, %%ebx\n\t” “movl %1, %%eax\n\t” “int $0x80\n\t” “popl %%ebx” : “=a” (res) : “i” (__NR_wait4), “0” (WAIT_ANY), “c” (status), “d” (0), “S” (0)); return res; } EOF ——————————————————–

export LD_PRELOAD=~/

now you can install.

Asynch I/O on SLES9 (

Let’s say that SLES9 at this stage seems to break async I/O compatibility with oracle.
A common error you could meet is:

ORA-27083: skgfrliopo: waiting for async I/Os failed

My guess is that the libc syscall(2) mechanism introduced by libaio 0.3.97 and above is not supported by oracle.
So my solution is quite simple. Download the sources of libaio 0.3.96-3 here, compile them with ‘make’ and then copy
in $ORACLE_HOME/rdbms/lib.

linux: # cp libaio.a $ORACLE_HOME/rdbms/lib
linux: # cp $ORACLE_HOME/rdbms/lib
linux: # ln -s $ORACLE_HOME/rdbms/lib/ $ORACLE_HOME/rdbms/lib/

in this way you still have the libaio-0.99 shipped with SLES9 on your system but oracle uses the 0.96 you provided.

If you don’t want to insert anything into your oracle installation tree you can create a directory wherever you wish and modify you LD_LIBRARY_PATH.

linux: # mkdir -p /usr/oracle/lib
linux: # cp libaio.a  /usr/oracle/lib
linux: # cp  /usr/oracle/lib
linux: # ln -s  /usr/oracle/lib/  /usr/oracle/lib/

Then relink the binaries with the command:

linux: # su – oracle
oracle@linux > cd $ORACLE_HOME/rdbms/lib
oracle@linux > make PL_ORALIBS=-laio -f async_on
oracle@linux > make PL_ORALIBS=-laio -f ioracle

and set

filesystemio_options=setall in you spfile
which enable direct I/O plus async I/O.

A good reference for the problem is Simon Grabinar’s webpage:

Reported Issues:
  Rainer Kaluscha (rainer.kaluscha _at_ reported and solved three issue met on this same architecture. With his consent I’m pasting the piece of mail covering them. Thank you Rainer! I encountered 3 problems not mentioned there. The solutions may be interesting for others so you might want to include them in your howto: 1. The database assistant refused to create a database with charset WE8ISO8859P15 – only WE8ISO8859P1 works … 2. ulimit: the user oracle had a limit on file size – so I ran into trouble when a datafile grew beyond 4GB … ulimit -f unlimited cured this (alternatively, one could probably also use osh) 3. The third one was trickier: I’m using the Intermedia text option. The INSO filtering utility ctxhx couldn’t be linked because only a 32bit version of ctxhx.o is present, the libraries are in $(OH)/ctx/lib32 and the makefile is ignorant on that. As ctxhx only works as a filter for temporary files I tried an executable from a 32bit machine. However, that one also had a (known) bug (undefined symbol: stat). By creating a dummy stat.c (cmp. like this: /* workaround for bug: undefined symbol: stat provides a function stat instead of inlined code */ #include <sys/stat.h> /* extern __inline__ */ int stat (__const char *__path, struct stat *__statbuf) __THROW { return __xstat (_STAT_VER, __path, __statbuf); } and including it into *before* the INSO libs: ctxhx: $(CTXHXOBJ) $(ORACLE_HOME)/ctx/lib/stat.o $(LINK) $(CTXHXOBJ) $(ORACLE_HOME)/ctx/lib/stat.o $(INSO_LINK) I was able to link and run ctxhx on the 32bit machine. Copying the executable to the 64bit machine and including the 32bit libraries in LD_LIBRARY_PATH did the trick. You might have to set an s-bit on ctxhx as it runs with the current user id while Oracle create the temporary files with owner/group oracle:dba …
