A LOCK ON THE NOTIFY LOG OR DB2DIAG.LOG CAN MAKE THE ENGINE SO SLOW THAT IT WOULD LOOK LIKE A HANG | |

Problembeschreibung: | |
A lock by another application or anything else on the notify log or db2diag.log file can potentially make the engine work very slow if there are lot of messages being asked to be written to the log files due to some condition in the engine ( such as lock escalation ). The engine can become so slow that it would look like a "hang". The situation is exasperated on a DPF system where all the nodes are writing to the same db2diag.log or notify.log file. | |

Local-Fix: | |
Viable workarounds include: 1) Find out who or what is locking the file(s) and kill that process OR 2) db2diag -A ( to change the log file ) -- ( but this will help only if the lock is on db2diag.log file ) OR 3) For DPF systems, have the logs split on Node numbers using the new functionality of DIAGPATH ( refer Infocenter ) OR 4) For DPF systems, have one local DIAGPATH for each physical servers OR | |
