When audit level for soa-infra is set to OFF, ISG is no longer working and below error is seen in SOA Suite log:
[2015-09-15T20:16:00.516+08:00] [soa_server1] [ERROR]

The issue can be reproduced at will with the following steps:
Login:EM ->SOA infrastructure Home->Common Properties
Disable the audit
It errors with : ORA-00001: unique constraint (APPLSYS.FND_SOA_REQUEST_UK1) violated in the
Once the audit is enabled there are no errors noticed.
Note : In either cases with or without audit enabled the response returned is fine, but the soa log shows the unique constraint error in case the audit is disabled.
Set audit level for soa-infra to ON.
However this workaround is not satisfying as it severely affects performance
