Description
Internal errors: IDB-2034: At least one DBRoot required for that query is offline
After upgrading mcs system was started successfully, mcsadmin getsystem status
did not return any failed state ,
however during queering
are received Internal errors IDB-2034: At least one DBRoot required for that query is offline.
The problem is that MCS started successfully and System is considered ACTIVE .
It seems that postConfigure script accepted invalid value of DBRoot IDs and Single Server installation finished with DBRootIDs assigned = 0 .
It would be expected to return Error for the invalid values of DBRoot IDs
or start MCS with an appropriate Internal Error System Status ,
otherwise system is considered ready for use but will return Internal errors .
MCS started successfully
