Shibboleth SP clustering using shared database

[William Lee]

Hello,

We have tried with Oracle RAC database cluster, but no luck:1. When one of Oracle RAC node is offline, SP stops working due to unable to connect to database (StorageService), it turned out Oracle ODBC driver does not support transparent fail over, their JDBC driver does.2. Occasionally getting ORA-08177 errors:2018-01-24 12:45:34 ERROR XMLTooling.StorageService [15]: error updating records (t=texts, c=_6f836ed1a7c5ab7ade92ae138f5e1e94)
2018-01-24 12:45:34 ERROR XMLTooling.StorageService [15]: ODBC Error: HY000:1:8177:[Oracle][ODBC][Ora]ORA-08177: can't serialize access for this transaction
2018-01-24 12:45:34 ERROR Shibboleth.SessionCache [15]: failed to update session expiration: ODBC StorageService failed to update context expiration.

I'm wondering if anyone was able to setup Shibboleth SP clustering? 

Thanks,
William
