I am getting following error while starting a newly added extract (datapump) process.
All existing processes are ok
ERROR OGG-00664 Oracle GoldenGate Capture for Oracle, PMP1CO.prm: OCI Error during OCIServerAttach (status = 12640-ORA-12640: Authentication adapter initialization failed)
Any limitations in number of extracts?
The solution for ORA-12640 is to change the parameter in SQLNET.ORA
from SQLNET.AUTHENTICATION_SERVICES= (NTS) to SQLNET.AUTHENTICATION_SERVICES= (NONE)
Give it a try to see if it works.
As far as the limitation on number of extract/replicat groups on one GG instance is concerned, it is defaulted to 300 and is configurable upto 5000 depending on the system resources that are available
