Tim, No, the error does not occur when we complete the transaction -- but obviously, we cannot control all transaction processing occurring at the time we want to perform the switch. It's not just the session that performs the switch that will error, all user sessions with uncommitted transactions will error. One of the things we are trying to do is use Res Mgr for chargeback purposes and we'd like to 'reset' the numbers for some interval measurements. We'd also like to perform switches for changes between diff types of processing loads (nightly/batch, day, etc). Res Mgr should be able to handle switches gracefully.

Jeff, Wouldn't it make more sense to complete the transaction before using ALTER SYSTEM? Does the error reproduce when you do that? -Tim on 3/25/04 6:47 AM, Thomas Jeff at jeff.thomas@xxxxxxxxxxx wrote: Wondering if anyone has experienced the following bug in Res Mgr (we are running 9.2.0.4 on AIX 4.3.3). We have a TAR in for this, but our experience is that tech support is completely hapless when it comes to Res Mgr issues. The error occurs when we switch plans while users have ongoing uncommitted transactions, their session will terminate with an ORA-600: internal error code, arguments: [kgskdecrstat1] when they issue a COMMIT. We had planned on implementing Res Mgr in our prod databases for various reasons, with a need to switch plans, so this is a big show-stopper. I can recreate the error in every database with something like the following: SQL> create table xyz as select * from dba_objects where 1=2; Table created. SQL> insert into xyz select * from dba_objects where owner = 'SYS'; 12561 rows created. SQL> alter system set resource_manager_plan = ''; System altered. SQL> alter system set resource_manager_plan = 'ES_RM_PLAN'; System altered. SQL> commit; commit * ERROR at line 1: ORA-00603: ORACLE server session terminated by fatal error -------------------------------------------- Jeffery D Thomas DBA Thomson Information Services Thomson, Inc.
