During a data collection run initiated by the MODIFY hisproc command, the system encountered an error that required that data collection stop. The output .SMP files are incomplete.
In the message text, the failuretext explaining the problem is one of the following:
Ensure that sufficient buffers are allocated for HIS data collection runs. You can specify the number of 4K data buffers per processor for use in sampling by specifying the BUFCNT keyword on the MODIFY hisproc command. To find the current BUFCNT setting, issue the DISPLAY HIS command during or after an instrumentation run. Then, if appropriate, specify a larger BUFCNT value on the MODIFY hisproc command.
Operator action: You can display a running count of lost samples using the DISPLAY HIS command. If occasional loss of data is tolerable, then specify DATALOSS=IGNORE, which is the default.
System programmer action: If sufficient buffers are assigned for HIS data collection and the error persists, verify that an appropriate dispatching priority has been assigned to the instrumentation task to allow it to write the full buffers to the file without delay.
Operator action: You must authorize to the sampling facility types specified on the SAMPTYPE parameter of the MODIFY hisproc command before starting HIS data collection runs. If you change the authorization for either the sampling facilities or counter sets that are in-use while data collection is active, the data collection ends prematurely. For information about how to set up the authorization of the sampling facilities and counter sets through the support element (SE) console, see Support Element Operations Guide for IBM® System z10™ machine on the Resource Link home page.
System programmer action: Avoid changing the authorization of the sampling facilities or counter sets during the HIS data collections runs.
Meaning: The authorization for the counter sets supported on this CPU changed while data collection was active. Data collection results are unpredictable. The .CNT output file might not be available.
Operator action: You must get authorized to the counter sets through the support element (SE) console before starting the HIS data collection. If you change the authorization of either the sampling facilities or counter sets that are in used while data collection is active, data collection ends prematurely. For information about how to set up the authorization of the counter sets through the support element (SE) console, see Support Element Operations Guide for IBM System z10 machine on the Resource Link home page.
System programmer action: Avoid changing the authorization of the sampling facilities or counter sets during the HIS data collection runs.
Operator action: If sampling data is lost because of internal hardware conditions, retry the operation. Report the error to the system programmer if the error persists.
System programmer action: If sampling data is lost because of internal hardware busy conditions, search problem reporting databases for solving the problem. If you cannot solve the problem, contact the IBM Support Center.
Operator action: If counter data is lost because of internal hardware conditions, retry the operation. Report the error to the system programmer if the error persists.
System programmer action: If counter data is lost because of the internal hardware busy conditions, search problem reporting data bases for solving the problem. If you cannot solve the problem, contact the IBM Support Center.
The system continues processing.
