Frequently asked questions

How many MVScope monitor sets can I run at one time?

Four monitor sets can be run at one time. If you try to start a fifth monitor set, you might receive a warning message.

How can I increase the number of monitor sets that I can run concurrently?

BMC Software does not recommend running more than four MVScope monitor sets at one time because doing so impacts system performance.

How many times can I sample the same job?

Sample a job as many times as you want; however, for each sampling, you will need a separate monitor set.

How do I start a monitor set for a job that is not running yet?

Start the monitor set in the usual way. MVScope will start sampling when the job is initiated.

My monitor set got dropped. Why? What do I do now?

The space for the monitor set was reused. If you want to prevent a monitor set from being dropped, use the DSLIST view to make the historical data set ineligible for recording. You cannot recover the monitor set record that was dropped.

The MSICCW view reports all I/O data as 'Not Authorized.' What is wrong?

The system administrator has not authorized you to collect or view data transferred by traced I/Os.

How can I make MVScope sample for longer than 1 minute?

You can use the CHAnge line command in MSLIST to change sampling parameters for a job that is in the Ready state. If you want to resample a job, select that job from MSLIST by typing ADD next to the monitor set name. Then change the parameters to what you want, save the new monitor set, and use the MONitor line command to initiate sampling.

How long are monitor sets in the Filed state? Why do they get dropped?

Monitor sets remain in the Filed state until their historical data sets are reused. If you want to prevent a monitor set from being dropped, use the DSLIST view to make the historical data set ineligible for recording. You cannot recover the monitor set record that was dropped.

How long are monitor sets retained in the PAS’s virtual storage?

Monitor sets are retained for five intervals; during that time, you can still view them even if you have no historical data sets.

Can I run MVScope in SSI mode?

No. MVScope actions are not supported in SSI mode.

Can MVScope trace activity on any kind of device?

No. MVScope can trace activity on DASD and tape but not on a printer.
