infdump
A user on Informix 7.31 asked why shmem files keep appearing in /infdump each time the server starts and stops, and what they are for. Replies explained they are shared-memory diagnostic dumps intended for IBM technical support to analyse failures, and that they should normally only be produced when the engine terminates abnormally (prompting jokes about kill -9). The poster then suggested the ONCONFIG DUMPSHMEM parameter (set to 1) as the cause and asked whether it should be enabled, but the thread records no answer to that final question.

Hi, I am using informix 7.31x, whenever i start and stop the server the shmem files are created in /infdump dir. what is the purpose of it and how can i analyse those files.
These are diagnostic files that IBM technical support can analyse as an aid to find the cause of failures They should not be created whenever you start and stop the engine. They should only be created if the engine aborts abnormally. How are you stopping the server? madh wrote: > Hi, > > I am using informix 7.31x, whenever i start and stop the server > the shmem files are created in /infdump dir. what is the > purpose of it and how can i analyse those files.

what about the parameter in onconfig dumpshmem. is it responsible for this shared memory dump. in manual i found that if dumpshmem is set 1 then it will dump shared memory for every startup and shutdown. do we need to set this. i request you to give some suggestions regarding this madu TBP wrote: > Paul Watson wrote: > >> scottishpoet said: > >>> These are diagnostic files that IBM technical support can > >> analyse as > >>> an aid to find the cause of failures > >>> > >>> They should not be created whenever you start and stop the engine. > >>> They should only be created if the engine aborts > >> abnormally.
