Sir:

As per requirement again from our 3rd party vendor in assessing our prod iseries 820 for system performance fine-tuning:

     "System storage information – Size and percentage allotted to SIBS and other system, usage, backup in the prod server."

      The main concern of the 3rd party vendor is on SIBS (Silverlake banking application) so naturally, they want to know the information as quoted above. How do i come up with the data output on this sir. Requesting for your expert advice. Thanks.



Software/Hardware used:
iSeries model 820 / V5R3

    Danmd5syste, You may want to be careful with the Display Object Description command, in that if you perform the command against a library you will see the size of the library but not necesarrily the contents. In that case you will want to use the Display Library command, DSPLIB LIB(MYLIB) OUTPUT(*PRINT). The printed version will included the size of the library and its contents. The other area of concern is does SIBS make use of the IFS ? If not, the DSPLIB to print should work for you. Hope this helps, Bill Poulin

    Run RTVDSKINF (and possibly RTVDIRINF) during off hours, e.g., over a weekend when little other processing is happening. After they finish, run PRTDSKINF RPTTYPE(*LIB) LIB(SIBS). The library name that I used was "SIBS", but you should use the name of a library that holds your SIBS data. You may use a generic* name if SIBS uses multiple libraries with similar names, or you can run the command for different libraries. Review the available parameters to see if other options might be useful. If you run RTVDIRINF, you can also run PRTDIRINF for additional streamfile and directory information. The two RTVxxxINF commands can run for long times, but their associated PRTxxxINF commands run fairly quickly. You can try to run the PRTxxxINF commands at any time to see if any data has already been collected. If you have been running RTVDSKINF regularly, then the information is available to be printed now.

    Sir Wpoulin: When you say : "The other area of concern is does SIBS make use of the IFS ?" How do i check on this one? Is there a way to know if IFS is being implemented by SIBS in our Prod Server? Currently, ill be submitting a job to run the RTVDSKINF as suggested by Sir TomLiotta and tomorrow, i can come up with the storage statistics that's being required by the applications head to cater to the 3rd party request. Thanks.

    Sir Tom: I finally extracted the storage statistics you advice using RTVDSKINF and the data i need is indeed reflected using this command. The PRTDSKINF shows all the libraries with their corresponding disk usage in percentage format and the sizes also so i think that the 3rd party vendor can already derive the data i can provide them. Thanks.

    If you have Help Systems Job Schedule, there is this command that keeps a running total how libraries change from week to week. Each report has four weeks of data, once you start running this CMD. Lib => ROBOTLIB Cmd => PRTDSKSPC

    Danmd5syste, As Tom stated, you can use the PRTDIRINF to show how much space on the IFS your SIBS application may be using. I would have no idea what their naming convention would be and so cannot tell you which directories you should review. Hope this helps, Bill Poulin
