ORA-00600: internal error code, arguments: [kewrpwrc_2: Invalid SWRF version], [3], [1], [], [], [],
Yesterday a customer of mine started an upgrade to Oracle 11g, but as this took more than 7 hours they aborted the upgrade and started to downgrade to Oracle 10.1.0.4 again.
After this was done several errors is shown in the alert log.
ORA-00600: internal error code, arguments: [16206], [4294952982], [], [], [], [], [], []
ORA-00600: internal error code, arguments: [kewrpwrc_2: Invalid SWRF version], [3], [1], [], [], [], [], []
Do not know what do as the support of this version has ended.
