  Since I did not have the password for database gguser, I modified the password from the database and recreated credentialstore using ggsci. 
  
 info credentialstore
 delete credentialstore
 create wallet.
 add credentialstore
 alter credentialstore add user gguser alias gguser.
 alter credentialstore add user GGUSER alias GGUSER
 info credentialstore
The reason we check credentialstore before deleting is to determine aliases.

Currently, I don't know if patching caused the issue or if it is a pre-existing condition. What's interesting is the same issue happened in a different system where environment variables for ORACLE_HOME and ORACLE_SID were not set for extract. Instead of restarting just the extract, all the processes were stopped and restarted. In summary, it would be a good idea to stop and start Goldengate processes before patching in order to determine any pre-existing conditions.
