RE: Many IFS files in directory

Aaron,
We ran into this problem when we were accumulated about 20,000
entries/day in a single directory. 

There is an IBM doc that states the maximum for an IFS directory (don't
have it at hand) but the max is essentially 1 million. I think this
could be more depending on certain criteria but even 1 million becomes
unmanageable.

We were up to the 900 thousand mark when our hand was forced since this
many objects really slows down the system backup and kills any job (or
Windows Explorer) that attempts to display the directory.  But failing
to do anything will be a real show stopper, I can promise. The best
solution was to archive everything for each day by zipping it all into a
single zip file whose name corresponded to that day. This worked for us
since our retrieval application is able to associate a date with each
entry so that when the original IFS file could not be found, an attempt
is made to unzip it from the zip file corresponding to that date.

Subject: Many IFS files in directory

I was just thinking today about a project that I am working on that is
cataloging 22,000 PDF invoices (per day) on a Windows machine and the
approach we have taken to ensure top performance is to put no more than
1000
files in each directory by dynamically creating new directories multiple
levels deep instead of putting all files in one directory.

I thought this was just a Windows problem but then a co-worker of mine
said
Linux had the same problem (or similar at least), and that got me
thinking
about all of the files I write out to the IFS with RPG.

Does anybody know if the IFS base file system suffers from the same
dilemma?

Thanks,
