Requesting the Application Checkpoint report

You can build Log Analyzer control statements manually or by using the Log Analyzer ISPF interface.

To request the Application Checkpoint report (manual method)

1. On the ANALYZE control statement, identify the source of the log data to be processed:

   • To specify the input log data explicitly, use the SLDS keyword:

     ANALYZE
         SLDS=(sldsName) ...

   • To specify the input log data implicitly, use the RECON keyword:

     ANALYZE
         RECON=(reconName) ...
2. If you specified the RECON keyword, add the INTERVAL keyword to specify the range of input log data to process. (If you used the SLDS keyword, including the INTERVAL keyword is optional.)

3. Enter a REPORTS control statement, and include the APPCHECK keyword to indicate the type of filters to use:

   • To create the report with default (internal) filters, use APPCHECK=ALL.
   • To use your own filters, use APPCHECK=yourCriteria.

   For more information about the subkeywords that you can use for yourCriteria, see APPCHECK-keyword.

   Note

   The filtering techniques that Log Analyzer uses to produce the Application Checkpoint differ from the techniques for producing most other reports. The FILTER control statement is invalid if you specify the APPCHECK keyword.

   The filtering techniques for the Application Checkpoint report accommodate a larger volume of input log records than the techniques for most other reports. The analysis job should take only a few minutes, even if the job is processing several day’s worth of data.

4. (optional ) If you want to request the Analysis Summary report, include the SUMMARY keyword. 

   Note

   The Analysis Summary report and the LUOW Summary report can provide supporting information to help with checkpoint-tuning efforts. Do not request any other reports. Other reports are likely to be too large to be useful.

5. (optional ) If you want to request the LUOW Summary report, include the LUOWSUMM keyword.

To request the Application Checkpoint report (ISPF interface method)

1. On the ANALYZE Control Statement panel (and supporting panels), identify the source of the log data to be processed.
2. On the INTERVAL Control Statement panel, specify the range of input log data to process.If you specified the name of a RECON, the range is required. If you specified the name of an SLDS, the range is optional.
3. On the REPORTS Control Statement panel, select the Application Checkpoint field.
4. Use the Application Checkpoint report options fields to specify report options.
