Hi Friends,

I have a question regarding this infamous error.

One of my customer has called us saying he's unable to connect to the Database and the error he was encountering with is TNS-12505.

When I tried connecting, It got connected immediately. I thought this is a problem with the dynamic registration etc... but the DB and the listener were running from long time and the registration technique we used is static here.

below is the log of continuous failure and success actions.

Please suggest

TNS-12505: TNS:listener does not currently know of SID given in connect descriptor
 *Cause:  The listener received a request to establish a connection to a
 database or other service. The connect descriptor received by the listener
 specified a SID for an instance (usually a database instance) that either
 has not yet dynamically registered with the listener or has not been
 statically configured for the listener. This may be a temporary condition
 such as after the listener has started, but before the database instance
 has registered with the listener.
 *Action:
  - Wait a moment and try to connect a second time.
  - Check which instances are currently known by the listener by executing:
    lsnrctl services <listener name>
  - Check that the SID parameter in the connect descriptor specifies
    an instance known by the listener.
  - Check for an event in the listener.log file.

Check the tnsnames.ora entry of your client.

Regards
Michel

Not your tnsnames.ora but the costumer's one.

It seems his CONNECT_DATA part is not correct.

we suffer from data obfuscation & don't know what is real & what is fake.
>(SID = aaku)
>(CONNECT_DATA=(SID=SID123)

Oracle is too dumb to lie.
When ORA-12505 was logged it did not know about the requested SID (whatever was actually being requested)
Consider filing a Service Request for assistance with problem resolution.
