I completed 11g to 12c migration successfully, After migrating, 12c rpd throwing 69 errors, it seems that all errors will displaying the same message like Initialization Block is not associated with a valid connection pool, LDAP servers or customer authentication.
If we debug one error we can close all errors in a single instance, Look the errors messages in below sc.
Please try to guide me to resolve these errors, help is appreciated
The message is quite explicit: open your init block and associate it with a connection pool.
PS: you have one init block by variable? You can probably have a single D_Current defining all your D_Current* variables ... : 1 query returning many columns vs many queries returning 1 column each, the first is better (less work for OBIEE and the DB).
