David, how did you determine that 50 was the optimum number?

Our server has 256MB RAM. Page space is 512MB.  The ADSM
server is the only application that is running in our SP wide node.

Is 50 the optimum for our configuration?

Also I've just found out that our system does not have the vmtune
command.  Do we need a PTF?

Your suggestion is appreciated.

Angel

      I do not think this is necessary.  The BUF043 problem should be
      fixed by
      IX87338 which is included in the 3.1.2.30 level.  The fix for the
      BUF006
      should be included in a future PTF through APAR IY00869.

      An underlying problem to the BUF006 appears to be an I/O
      bottleneck preventing
      dirty pages from getting flushed fast enough.  A circumvention to
      that
      problem that has worked for at least one customer is

      vmtune -P 50

      I would try this first.  APAR IY00869 will fix the BUF006 problem,
      but you
      will still have the problem of memory utilization and the I/O
      bottleneck
      after that fix which the vmtune setting should resolve.  If the
      I/O
      bottleneck is resolved then you should never get into the
      condition
      that causes the BUF006 problem which is a timing problem that
      only occurs when the data base buffer pool is full of used pages.
