Some of you might thought to use Oracle RAC as ME database, but did not find instructions how to configure it.
The reason is that Oracle RAC has not been officially certified for SAP ME 6.1, yet.. In particular, SAPMECTC does not allow configuring ME datasource pools for RAC.
However, it is possible to manually change ME datasource pools. On your own examination you can try a string like this for the WIP connection pool:
But there are no officially documented instructions on this. You need to contact SAP ME Consulting team if you need this to be elaborated.
Or you can try setting oracle tnsnames.ora to use SID instead of Service name. Once applied, CTC may continue. It can be either reverted to use service name after that or to keep using SID since ORACLE RAC will replicate into the other DB any changes. But there are no officially documented instructions on this too, so, again, you need to contact SAP ME Consulting team if you need this to be elaborated.
