error occured use hashed file
error occured use hashed file
This is a topic for an orphaned message.
Mr Kim,
How full is the file system /data/Ardent? (this is pointed to by
DS_MMAPPATH) and is where the memory mapped pre-loaded hashed files are kept. The fact that you have very many heap and hash files there suggests that there may not be enough space left to create those needed for the job that is failing.
The hash and heap files are supposed to be cleaned up (removed) automatically when a job completes successfully. Have you had jobs that use large hashed files fail to complete successfully? If you have stopped UniVerse, it is safe to remove all hash and heap files - they are only used by UniVerse processes.
You also asked about DS_MMAPSIZE environment variable. This is used to set the size (in MB) of each of the files used to store the mapped pre-loaded hashed files - that is, the files in DS_MMAPPATH directory.
Regards,
Ray
