Installing Patch for RAC on Linux RH 4 - 64 bits

Before installing Patch on Red Hat 4 - 64 Bits, update 2,  install this rpm:

rpm -Uvh binutils-

Download it here: http://oss.oracle.com/projects/compat-oracle/files/RedHat/

Following all details of what may happen if you dont do that:

My first experience with patch was on Red Hat 4, 32 bits. It  did install in about an hour, or less, including CRS, ASM and RDBMS homes, before creating a database.

On 64 bits it took much longer ... CRS was patched nicely; then I went to patch the ASM home, the relink step failed with:

Error in invoking target 'all_no_orcl ipc_g' of makefile

After trying for a while to find a solution I did continue the install ignoring the error, the patch installation finished successfully but ASM failed to start with:

ORA-27504: IPC error creating OSD context

Working with support I got to understand that the initial error on the relink step can be avoided by installing the following RPM, for Red Hat 4 update 2:


The rpm can be downloaded here: http://oss.oracle.com/projects/compat-oracle/files/RedHat/

Install it using:       rpm -Uvh binutils-

After installing the rpm I did 'relink all', seting up your ORACLE_HOME environment variable, execute $ORACLE_HOME/bin/relink all

This was noth enough to solve the problem, ASM still refused to start and returned
ORA-27504: IPC error creating OSD context.

On the trace generated I did see:

Number of resource hash buckets is 472
* kjfcnfy: kjinumbuckets = 512
libskgxpd.so called
libskgxp9.so should reference real implementation
IPC OS error without diagnostic information

A reference on Note 399189.1 pointed to the solution: copy libskgxp10.so to $ORACLE_HOME/lib from a 'working' install, and relink. The only working installs I had at hande were homes, so I brought the file from there, I did relink and after that ASM started immediately.

Then I did the patch on the RDBMS home; it didn't fail.

Installing rpm
binutils- worked.
