QMGTOOLS: Summarize Library

How To


Summary

The Library Size Summary (LIBSIZSUM) tool shows the number of objects in the specified library and the total size of the library and all of it's objects.

It has an option to display all of the objects in the library sorted by size, and lists the top 10 users of storage by:
- Individual object
- Generic objects (grouped by first 5 characters of the object name)
- Object type
- Owning user profile

Steps

If you do not already have the IBM i Support MustGather tools installed, or if it is not current, please see the following document for install and update instructions - https://www.ibm.com/support/pages/node/645929


The Summarize Library tool can be initiated from the Must Gather Data Collector menu:

GO QMGTOOLS/MG  =>  Internals  =>  Storage Management Menu  => Permanent Storage Menu => Summarize Library

 

You can also access the tool directly - QMGTOOLS/LIBSIZSUM


Specify the name of the library you want storage information for.

Here is an example screen showing size summary information for library QMPGDATA.  The top part of the screen shows the number of objects in the library and the total size of the library and all of it's objects.  Below that is a list of the top ten objects listed by size.

Pressing F11 will rotate forward through the Top Ten reports, while F10 will move backward through the Top Ten reports.  Pressing F11 while viewing the top 10 individual objects will switch to the top 10 generic objects, which groups the objects using the most space by the first five characters of the object name.
