SAS^® 9.2 Test Monitors for z/OS and Windows

SAS 9.2 for z/OS Enterprise Business Intelligence (EBI) sites that rely on OLAP applications for their computing environment require highly tuned and efficient OLAP server responsiveness. Optimizing the OLAP server computing resources is therefore critical to a succesful OLAP server deployment and implementation.

The facilites and tools available with the Z/OS REXX Monitor for SAS 9.2 package provide a foundation that customers may implement to tune their SAS 9.2 deployment for z/OS.

Overview

There are three key componenets that comprise the package:

• RXMON - a REXX and SDSF based tool for collecting performance data on z/OS. This includes SAS code to process the log files into a SAS Performance Data Base (PDB).

  The following diagram shows the data flow of RXMON.

• MXPMON - a REXX based tool that uses the Mainstart MXI package by Rocket Software to gather more detailed data from the z/OS system.

  The following diagram shows the data flow of MXPMON.

• Ntsmfr,Ntsmfj,Ntsmfread - A set of SAS programs to read NTSMF log files, created by the NTSMF product from Demand Technology Software. These programs create a Performance Data Base (PDB) that can be used in conjunction with the PDB's from RXMON or MXPMON.

  The following diagram shows the data flow of the NTSMF SAS tools.

Installing the TestMonitorTools Package

Customer can request the package by sending an email to our SAS R&D development team, REQUEST TestMonitorTools Package.

1. Download the .zip file via the email sent from SAS R&D.
2. Files in the zOS directory must be transferred to your z/OS system and saved in PDS datasets of appropriate type. The files are all text files and will need to be converted from ASCII to EBCDIC. If you use FTP to transfer the files it will do the conversion.
3. Once on z/OS the files in the SOURCE directory must be assembled into a load library. The assembly jobs will need to be edited first to alter the data set names used for the output library, and other job accounting info for your site.
4. The CNTL directory contains JCL for running both the RXMON and MXPMON test monitoring jobs. Before running either of these jobs the JCL must be edited to set the dataset names and other parameters.

   For MXPMON

   • You must have MXI installed.
   • The name of the MXI library must be set correctly on the steplib DD statement.
   • The parameters in the MXPCFG REXX member must be set for your site and specific test.
   • The userid and high level qualifier must be set for the job.

   For RXMON

   • The parameters in the SYSIN DD statement must be set for your site and specific test. These are documented in the comments at the front of RXMON REXX.
   • Read the notes section of RXMON REXX, specially part 3, as the number of address spaces running on the system can have an impact on how the monitor captures data.
   • The userid and high level qualifier must be set for the job.

5. If you have NTSMF the SAS programs in the \Windows\SAS may be usefull, however the MXG product may also be used to read this data.

   To use these sas programs:

   • Run ntsmfr.sas against one of your log files. This will create a WORK library SAS dataset containing meta information about the NTSMF log files you are currently generating.
   • Then in the same session run ntsmfj.sas to generate the SAS code called ntsmfread.sas for your system. The ntsmfread.sas file supplied here is simply an example based on the log files used at the SAS site.
   • The ntsmfread.sas will need to be modified by hand before it is run to set the names of the input log files and to set the name of the PDB for the test.
