Question
How do I predict when it is worthwhile to perform a manual_vacuum on NPS?
Answer
Use the following equation to determine whether performing a manual vacuum process will be beneficial:
If the (size of the /nz/data directory)– (size of cache) – (size of core files) is greater than or equal to 4 GB, then you should perform a manual vacuum.
To get the size of the /nz/data directory, run the nz_catalog_size command.
To get the size of cache, run the following command: du -sh /nz/data.1.0/cache/
To get the size of core files, look at the output of the nz_catalog_size command.
The following is sample output for the nz_catalog_size command:
[nz@Test ~]$ /nz/support-TwinFin-5.0-100129-1546/bin/nz_catalog_size | more
/nz/data ( total directory size: 15G inclusive of 0 MB of CORE Files)
...
...
The nz_catalog_size command is located in the /nz/support/contrib/<version>/bin directory, where <version> is NPS Release 4.5 or later.
