Using a 220.127.116.11 webgate with an OAM 18.104.22.168 agent may result in the error: “The underlying wallet operation failed.” raw_code^223.
This is caused by the 22.214.171.124 file cwallet.sso, which is not compatible with 126.96.36.199. It needs to be converted at the 188.8.131.52 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.
