OID is Down For Ambiguous Reasons

Posted on May 27, 2015December 23, 2018 by Osama Mustafa in Fusion Middleware

Today one of the customer called complaining about accessing to the system and how its not working ? Since everything is configured as single sign on (SSO) first thing to check was OID or oracle internet Directory.

The logs indicate to the below error :-

[2015-05-01T07:00:18+03:00] [OID] [NOTIFICATION:16] [] [OIDMON] [host: MOAPRDOID1] [pid: 5244] [tid: 0] Guardian: [oidmon]: Unable to connect to database,
will retry again after 10 sec

[2015-05-01T07:00:28+03:00] [OID] [NOTIFICATION:16] [] [OIDMON] [host: MOAPRDOID1] [pid: 5244] [tid: 0] Guardian: Connecting to database, connect string is oiddb

[2015-05-01T07:00:28+03:00] [OID] [NOTIFICATION:16] [] [OIDMON] [host: MOAPRDOID1] [pid: 5244] [tid: 0] Guardian: [gsdsiConnect] ORA-12514, ORA-12514: TNS:listener does not currently know of service requested in connect descriptor.

from the above error the OID is unable to connect to database server i checked database and listener everything is up without any issue and all the other application working without any issues.

after investigation I checked the sqlnet.ora and add the following :-

SQLNET.AUTHENTICATION_SERVICES= (NONE)
NAMES.DIRECTORY_PATH= (TNSNAMES)

Restart the services and everything is working.

maybe this solution will not lead or help in so many cases i am working to know why this will effect on OID since it’s was working without any issues for 1 year

Thanks

Oracle SOA Tablespace Is full

Posted on October 26, 2014December 23, 2018 by Osama Mustafa in Fusion Middleware

When Creating Domain for Oracle SOA it’s Mandatory to Run Oracle RCU before to create SOA Repository, This will create tables configuration and information about Oracle SOA.

But What happened the this tablespace was getting full, increase it 20GB is not enough which mean it’s strange case and not acceptable.

after investigation Table Called “REFERENCE_INSTANCE” include information about Running Composite in SOA ans instances. the size for this table 18GB.

Select * from Reference_instance;

Check the data in the above query, just in case you can use export data-bump utility for this table, however after this Truncate the table and from full tablespace toonly 2% usage.

Thank you
