Re: Memory Limits for UNIX Client: What should they be?

2002-02-13 Thread Jeff Bach 

Paul,

This client has 4 Gigs memory and a 560 Meg maxdsize.  HPUX 11.0

1.  Count files per subdirectory to find where they concentrate.
2.  Run backup, watch physical memory and ps -el | sort +9n to
see if you hit kernal parameter or hardware limit.
3.  Add memory .. tune maximum amount of physical memory allowed
to a single process (maxdsize) on HP.

Jeff

 Subject:  Memory Limits for UNIX Client: What should they be?

 We have an SGI client with 65/512.  Trying to find out if these are
 kilobytes or megabytes.  The backup fails because it runs out of memory.
 MemoryEfficientBackup does not help.  -dirsonly does not help.

 What are people using on large UNIX filesystem clients for these numbers?
 There are probably 7 million files in this file system of about 1TB.

We just had this kind of problem with HP-UX. Tivoli support quoted an
estimate of 300 bytes per active backup file. Our experience suggests that
this estimate is a bit conservative. With a 536 megabyte limit on the data
segment size we started running out of memory when the number of files was
somewhere between 2.9 million and 3.1 million files. This corresponds to
using somewhere between 173 and 185 bytes per file.
