Here is a list of options to which you should pay special attention when you are installing MFX:
- KEY-related parameters: KEY, KEYDSN, KEYMSG, KEYWARN
MFX requires a license key for every CPU on which it is run. These options support the installation of the keys, the use of key data sets, and the control of key-related warning messages.
Note: You do not need new license keys for Syncsort™ MFX 3.1 if you have valid keys for release 2.1. Also, the Syncsort™ MFX 3.1 license does not affect existing licenses for Syncsort PipeSort, Syncsort PROCSort, and Syncsort ZPSaver.
- SVC
An SVC allows MFX to use its high performance access methods, to optimize the performance of DASD with cache, and to support the key data set facility. MFX also uses its SVC to create SMF records.
If you are converting from an earlier release, use a different SVC number for MFX than the one you used previously. This will facilitate testing.
- MINCORE
The MINCORE option specifies the minimum amount of virtual storage that will be available to MFX. Make sure that the MINCORE value is high enough to support all the sorts at your installation.
- VSCORE, VSCORET
The VSCORE option specifies the maximum amount of virtual storage available to MFX below the 16-megabyte line.
The VSCORET option specifies the total amount of virtual storage available to MFX below and above the 16-megabyte line when MFX’s Dynamic Storage Management (DSM) facility is inactive. When DSM is active, the setting of the VSCORET option is treated as an initial recommendation.
- DSM, DSMWEND
The DSM and DSMWEND options allow you to set the optimization mode for all the sorts run on your system. You can direct MFX to provide the best overall balance of CPU time, elapsed time (wall clock time), and I/O activity, or you can direct MFX to minimize the use of one of these three. DSM and DSMWEND also allow you to vary the optimization mode during specific time intervals and to control local DSM.
STGPCT is a parameter of DSM/DSMWEND that provides users with an option to significantly improve elapsed time performance using more real storage in a highly controlled way. STGPCT creates dynamic optimization to control the maximum amount of real storage for MFX processing. MFX can utilize storage as a memory object to hold temporary SORTWK data rather than using a DASD SORTWK. Increasing the amount of memory object space can improve sort elapsed time (usually with minimal increase in CPU time, if any).
- JAVAHOME, JVM64, JZOSHOME, SYNCHOME, HOSTNAME, PORT
These options need to be defined to support the OUTFIL OUTPUT facility to create PDF, RTF, and HTML files and email them. These options are discussed in this chapter as well as in the Preliminary Tasks sections of the installation chapters.
