Oracle on Linux Installation for Non-DBAs Sheryl Calish Blue Heron Consulting Paper #36684

Introduction  Linux Installation  Oracle Installation  Most Recently:  Oracle 9i (Release 2) on SuSE 8.0 (kernel )  Past installs:  Oracle 9i on SuSE 7.2 (kernel 2.4.4)  Oracle on Red Hat 6.2 (kernel )

Linux Installation  Hardware and System Considerations  Linux distributions  How to prepare for a Linux installation

Oracle Installation  Preparation tasks  Reported installation issues  Recommendations for novices

Hardware and System Considerations  To check for compatibility with Linux and Xfree86  To ensure proper configuration of your system  To enable others to help you, if something goes wrong

Partitioning Rationale "Partitioning Your Hard Drive": "4.3 Partitioning Hard Drives(s)" : easy/install-partitioning

Optimal Flexible Architecture Four separate mount points: /u01, /u02, /u03, /u04 each in its own partition

Two References "Tips for Installing and Configuring Oracle9i Database on Red Hat Linux", from OracleWorld 2003 "Installation Instructions for Oracle 9i Release 2 (9.2.0.x) on United Linux 1.0 based Linux systems", from

Swap Space  Oracle 9i installation requires swap space to be equal to physical memory or 1GB, whichever is greater  A temporary swap file can be used

Run Linux Installer  Follow the documentation for your distribution  Check with your Linux distribution for the latest updates and patches

Prepare for Oracle Installation  Make sure appropriate software is installed  Create the database administrator groups  Create the Oracle user  Create mount points  Modify kernel parameters  Set environment variable s

Required Software rpm -q k_deflt > k_deflt rpm -q glibc > glibc rpm -q binutils > binutils

More Required Software rpm -q gilbc-locale >glibc-locale rpm -q make >make rpm -q gcc >gcc

Database Administrator Groups As root : From menu in SuSE: System -> Configuration -> Create group From command line: groupadd oinstall groupadd dba groupadd oper Paper #36684

Create Oracle user As root : From menu in SuSE: System -> Configuration -> Create user From command line: useradd oracle -g oinstall -G dba,oper

Mount Points If you did not create the partitions for these you can create the mount points now, then, As root, change ownership: chown oracle.dba /opt/oracle (or /u01) OR chown oracle.oinstall /opt/oracle chmod 775 /opt/oracle (or /u01) Run the same command for /u02, /u03, /u04

Kernel Parameters Oracle documentation warns of possible installation or production problems if the settings are insufficient SHMMAX

Environment Variables As oracle user Three sources: 1) Oracle Metalink 2) 3)orarun9i.rpm (run as root)

orarun9i.rpm can be downloaded from SuSE sets up most environment variables in /etc/profile.d/oracle.sh sets kernel parameters sets up automatic startup/shutdown of Oracle look at /usr/share/doc/packages/orarun9i/README

New orarun For SLES8 and SuSE 8.1 use: orarun SL80_81.noarch.rpm Major difference is location of : /etc/profile.d/oracle.[c]sh has been moved to: /etc/sysconfig/oracle Paper #36684

Oracle9i RHL Run Package Oracle9i RHL Run Package Available from GURU LABS Based on orarun9i.rpm from SuSE modified to work with Red Hat

Functions of RHL Run Provides: /etc/init.d/oracle /etc/profile.d/oracle/sh|chs (requires edits) /etc/sysconfig/oracle (requires edits) /usr/share/doc/oraclerun9i-1.4/INSTALL

Temporary swapfile # become the root user su - # create a 1GB file (or any value for "count") dd if=/dev/zero of=/swapfile bs=1k count= # make it a swapfile mkswap /swapfile # activate swapon /swapfile

Run Oracle Installer Oracle 9iR2 installation took 45 minutes with 512MB and 1GB of swap space Oracle 9iR1 installation took 1 hour with 512MB and 658MB of swap space Oracle installation took 15 minutes with 512MB of RAM and 1GB of swap space

Install Cleanup In order to run Oracle Installer after an incomplete install From rm -rf /etc/oraInst.loc /etc/oratab (/tmp/OraInstall ?) rm -rf $ORACLE_BASE/* /tmp/ Paper #36684

Installation Issue #1 Issue: Inability to access another program after Oracle installation Solution: Add $PATH before you enter other path variables

PATH Example Instead of: PATH=/bin:/usr/bin:/usr/sbin:/etc:/opt/bin:/usr/cc s/bin:/usr/openwin/bin:/opt/local/GNU/bin Enter: PATH=$PATH:/bin:/usr/bin:/usr/sbin:/etc:/opt/b in:/usr/ccs/bin:/usr/openwin/bin:/opt/local/GNU /bin

Installation Issue #2 Issue: Incompatibilities between some versions of Oracle and glibc or binutils of some versions of Linux Examples: Red Hat 7.0 and Oracle have a glibc issue Red Hat 7.1/7.2/7.3, AS 2.1 and Oracle 9iR1 have a binutil issue Sun JDK and SuSE 7.2 have a glibc issue

9iR2 and Red Hat 8.0 From " Error in invoking target install of makefile: /opt/oracle/product/9.2.0/ctx/lib/ins_ctx.mk " Edit $ORACLE_HOME/ctx/lib/env_ctx.mk and go to " INSO_LINK = ", add a " $(LDLIBFLAG)dl " to the line and save it.

9iR2 and SuSE 8.0 From suse-oracle mailing list " Error in invoking target ntcrontab.o of makefile: /opt/oracle/product/oracle/network/lib/ins_int_client.mk"

9iR2 on SuSE 8.0 (con't) First solution: Edit the file $ORACLE_HOME/sysliblist add the following to the existing line - L/usr/lib/gcc-lib/i486-suse-linux/ lgcc the line becomes something like this: - L/usr/lib/gcc-lib/i486-suse-linux/ lgcc -ldl -lm -lpthread Paper #36684

9iR2 on SuSE 8.0 Second solution: look in $ORACLE_HOME/install/make.log for linker errors (eg. lack of the library clntsh. (ld reports cannot find -lclntsh) go to $ORACLE_HOME/bin and run the command 'genclntsh' (as user oracle)

Installation Issue #3 Issue: Some have reported that the Installer hangs during installation Enter: unset LANG Then run Oracle Universal Installer

Installation Issue #4 Issue: Mounting and unmounting cdrom Run Oracle Universal Installer as Oracle user From Oracle user directory: mount /media/cdrom /media/cdrom/oracle9i/runInstaller unmount /media/cdrom DO NOT cd to cdrom directory to./runInstaller!

Recommendations  Decide on the version of Oracle you want to install and work backward.  Choose the version of the Linux distribution with the same binutils and glibc as the certified version.  Oracle 9iR2 reported to install smoothly on Red Hat 7.3, 8.0, SuSE 8.0, 8.1 and 8.2.  Check that your hardware and system components are supported by your chosen Linux distribution - especially for Xfree86.
