If we have the following setting in Logarchmeth1 TSM:MCA_DWH_LOGS1 being MCA_DWH_LOGS1 the TSM Management Class for archiving logs, on database restart we might experience the following errors if we previously crashed with open transactions and the database was left in an inconsistent state: 2010-01-27-11.55.22.589466+060 E209394A896 LEVEL: Error (OS) PID : 4075576 TID : 2830 PROC : db2sysc 5 INSTANCE: db2001dw NODE : 005 DB : DWH00001 APPHDL : 5-51 APPID: *N5.db2001dw.100127105522 AUTHID : DB2001DW EDUID : 2830 EDUNAME: db2agent (DWH00001) 5 FUNCTION: DB2 UDB, oper system services, sqlomkdirp, probe:10 MESSAGE : ZRC=0x840F0001=-2079391743=SQLO_ACCD "Access Denied" DIA8701C Access denied for resource "", operating system return code was "".
