If you have been following the last 4 posts, you now know everything about the journal analysis report except for how to run the command. In this post we will cover running DMANZJRN.

Using go DMREPORTS choose option 10 Journal analysis reports or just CHGCURLIB ICLUSTER and prompt the DMANZJRN command. You will see the screen below:


The first parm is JRN. This is pretty obvious, specify a single journal name or library, or *ALL which indicates that all journals currently used by iCluster will be analyzed including QAUDJRN. You can also specify *ALLDATA which just eliminates QAUDJRN – in other words just database journals. Note: That for *ALL or *ALLDATA iCluster must currently be scraping the journals in order for the command to analyze the journal.

If this command is being used prior to iCluster installation for bandwidth analysis, specify a single journal with CLRANZ(*YES) to start with a clean analysis file. On the second run for a different journal, specify CLRANZ (*NO) which will append the data from the first run with the second run and then run the analysis. This may take more time.

The next two parameters are STRJRNRCV and ENDJRNRCV which tell the command where to start and end the analysis. The defaults are STRJRNRCV(*CURCHAIN) for starting location (the first journal receiver in the chain for the journal being analyzed) and ENDJRNRCV(*CURRENT) for ending location (the currently attached receiver). You can also specify specific journal receivers and libraries for both values. Note that if *ALL or *ALLDATA is specified for the first JRN parameter, you cannot specify a specific receiver for these values obviously.

The next four parameters STRDATE, STRTIME, ENDDATE and ENDTIME, specify the starting and ending dates and times (in the format of the journal’s date format) for the receiver range specified in the previous two parameters (STRJRNRCV and ENDJRNRCV). If these values are not specified (or the values that are specified are not in the receiver range specified), the default is to start with the earliest entry in the receiver range and end with the last entry in the last receiver in the range specified.

The final parameter is CLRANZ and specifies whether the data in DMANZJRNPF which contains raw data before the analysis is done is cleared before adding new data from the current run. The default is *NO.


In the command shown above, we are analyzing the WTRJRN journal in library AAAJRNLIB, from the earliest receiver in the chain through to the current receiver but only for entries between June 1st 2015 at 4:00am and June 15th at 5 minutes to midnight. We are also starting with a clean analysis file.

Analyze your journals often to get a good feel for what’s happening on your system!
