iSeries dasd growing at abnormal rate

[tbrowne]

I have an iSeries 9406/520 running OS/5.4.0. Over the past several months dasd usage has been growing at an abnormally high rate and I need to find out why. I'm looking for a way to monitor files or libraries that grow more than say three percent in a given period of time to identify where the problem is. I don't have any money to throw at the problem so it has to be done in-house. Any and all ideas on how identify the file or library where the growth is occurring will be greatly appreciated.

One place to start might be to use the command

DSPOBJD OBJ(QSYS/*ALL) OBJTYPE(*LIB) OUTPUT(*FILE) OUTFILE(lib/file)

The file will have all of the libraries and their sizes. You'll have a starting point. You can then put DSPOBJD on the scheduler to run daily, weekly, monthly, whatever. Send that output to a different file and run a query against the two files comparing sizes.

You can do the same thing with files.

DSPOBJD OBJ(*ALL/*ALL) OBJTYPE(*FILE) OUTPUT(*FILE), etc.

You will get all files including logicals, display, and printer files.

Another command is DSPFD. You can specify the type of file to be only physical files.

DSPFD FILE(*ALL/*ALL) TYPE(*MBRLIST) OUTPUT(*OUTFILE) FILEATR(*PF)

The member list will give you the sizes for each member.

Good luck.
