Using a 18.104.22.168 webgate with an OAM 22.214.171.124 agent may result in the error: “The underlying wallet operation failed.” raw_code^223.
This is caused by the 126.96.36.199 file cwallet.sso, which is not compatible with 188.8.131.52. It needs to be converted at the 184.108.40.206 OAM server with the command:
/oracle_common/bin/orapki wallet convert -wallet ./cwallet.sso -auto_login_only
Copy the converted cwallet.sso to the webgate and restart.
