Applies to:

Oracle Internet Directory - Version 11.1.1 to 11.1.1 [Release 11g]
Information in this document applies to any platform.


OID server becomes unresponsive if a node of the RAC database is down.
Multiple OID 11gR1 servers installed non-clustered behind load balencer. Servers connected to two-node RAC Database with SCAN configured.
When shutting down one node of the RAC. both OID servers became non-responsive until the node was restored.

oidmon.log file sample error message:

[2015-06-22T15:09:39-04:00] [OID] [NOTIFICATION:16] [] [OIDMON] [host: <HOSTNAME>] [pid: <PID>] [tid: 0] Guardian: gsl
dudiSetSqlStmt: Sql prepare failed (SELECT attrname, attrval from ds_attrstore where entryid=899 )
  ORA error = 3114 message = ORA-03114: not connected to ORACLE


A similar issue can also be encountered during initial installation/configuration when using a RAC database configured for SCAN addressing, where it hangs at the "Create Oracle Internet Directory" configuration step and the install*.log shows:
