Initialization of sysroles and sysusers in database %1! failed due to missing system role '%2!' in master..syssrvroles.
While in the process of upgrading the server or upgrading a database, Adaptive Server detected that a system role is missing.
Check the master..syssrvroles table to see if the reported missing role is there. If this role had been manually removed by deleting a row from the syssrvroles table, it must be readded to the syssrvoles table.
