BMC AMI Capacity Reporting
UIE creates a lot of tables for Visualizer but in some cases some of the information is not needed anymore.
UIE creates e. g. tables which capture information about Suites and Subsystem Address Space and the DASD devices which they use. Here two examples showing this information in Visualizer and AMI Capacity Reporting:
Most customer are not interested in this information. And on the other side the tables can become very large when Suites or Subsystem Address Space use a lot of DASD devices which they normally do.
While reading the SMF data UIE extracts information about DASD usage into a temporary dataset, starts an internal sort and has a second temporary dataset as output for this sort process. To get rid of this information we have to specify these four DD statements in the UIE job:
//SDVAIN DD DUMMY,RECFM=VB,LRECL=4096,BLKSIZE=0,DSORG=PS
//SDVAOUT DD DUMMY,RECFM=VB,LRECL=4096,BLKSIZE=0,DSORG=PS
//SSDAIN DD DUMMY,RECFM=VB,LRECL=4096,BLKSIZE=0,DSORG=PS
//SSDAOUT DD DUMMY,RECFM=VB,LRECL=4096,BLKSIZE=0,DSORG=PS
Results will be a smaller Visualizer file, less I/O’s done by UIE which together with some CPU savings will end up in a shorter elapsed time.
