Periodically Checking Maximum Dump Size

Use the DTODSIZ utility to periodically estimate dump file size, based on system activity occurring when DTODSIZ is executed. Execute DTODSIZ (either interactively or in a scheduled job) during times of peak system activity to estimate the largest possible dump for your system.

	NOTE: Hewlett-Packard recommends that the DTODSIZ utility be used twice per week until the estimates that you get are fairly consistent. After this initial period, continue to use DTODSIZ monthly during peak periods of system activity to confirm that dump files managed by BLDDUMP are big enough to handle your system's largest possible dump.

To execute DTODSIZ, enter the following at the system prompt:

   :RUN DTODSIZ.HP36375.TELESUP

When DTODSIZ runs, it displays the megabyte size that a dump file must be to hold dump information when a dump occurs. The DTODSIZ utility checks the size of dump files managed by BLDDUMP and tells you if the files are too small for the estimated dump size.

If you find that dump files are either too large or too small, execute BLDDUMP and use the ALTSIZE command to change the size of each dump file to the new maximum size estimated by DTODSIZ.
