Enable hash file cache sharing
Posted: Wed Mar 03, 2004 2:12 am
Hi PPL,
I've need someone to please set me straight on Hash file cache sharing as I have been getting conflicting answers.
The option to "Enable hash file cache sharing" in a server job's properties means that a memory resident hash file will only be available to stages in that job and multiple invocations of that same job. Is my understanding of that correct
If that is the case, does that mean that when multiple DIFFERENT jobs running at same time referring to the same hash file, will each create a copy of the hash in memory This seems to be the case when I take a look at the memory usage of my machine when these jobs are executing
If that is the case is there any way to make multiple different jobs use the same in memory hash file
Thanks,
Tom.
