Applies to:Oracle Internet Directory - Version 11.1.1 and later
Information in this document applies to any platform.
Oracle Internet Directory (OID) 11g, i.e., 126.96.36.199, with underlying RDBMS (RAC) Database (DB) 11g, i.e., 188.8.131.52.
A firewall exists in between OID and DB. The firewall kills the connections between OID and DB when they are idle for more than 30 minutes.
This causes the OID server to enter in a status in which it is not able to contact the DB anymore so every client requesting LDAP operations times out.
The only way to restore the connections is to restart the OID server.
OID server log file shows:
ConnID:7 mesgID:32 OpID:31 OpName:search ConnIP:::ffff:<IP Address> ConnDN:cn=orcladmin
[gsldfb_FetchBaseObjs] ORA error 3135: ORA-03135: connection lost contact
Process ID: 22115
Session ID: 78 Serial number: 2689
