One of the following Oracle patches is required before enabling RDS in Oracle 11g. There are separate patches for 22.214.171.124 and 126.96.36.199. The patch is required before enabling RDS. If RDS was enabled before installing the patch, then RDS will need to be re-enabled after installing the patch (the patch reverts back to the non-RDS shared library). The steps to enable RDS are listed below.
The Oracle binary must be relinked to enable the RDS protocol for the cluster interconnect. This process should be done for all Oracle database homes and ASM home where you want to use RDS. Each instance of the same database or ASM needs to use the same protocol. If you're using local storage for the ORACLE_HOME file system then you need to enable RDS in each database or ASM ORACLE_HOME on all nodes. You can enable RDS using the following steps for each database or ASM ORACLE_HOME:
To go back to the original (UDP) protocol repeat the above five steps, except only in step 4 execute the following command: make -f ins_rdbms.mk ipc_g
