Hi All,
Two days back i have faced some funny issue in my project. Issue was, suddenly hostname and url prefix got disappear from oracle policy manager. I couldn’t able to see hostname/url prefix under resource tab which we have already configured. I’m wondered how it happened suddenly.
Here i would like tell you how I found the issue and how i fixed it.
1. First enable the OID into debug mode, parameter flag orcldebugflag from 0 to 1 and orcldebugop from 0 to 511. More details Metalink ID: 397821.1
2. Then reproduce the issue.
3. Captured the ldap logs, from this logs i got some clue about the issue. There is a lot of MissingEdn errors in OID. It mean, response for search query is not complete some of the search response were missing.
Solution:
========
Based on error, i have found two metalinks which deals this issue.
