And one of the nodes is primarly for batch job which parameters. Do I have to adjust to make job run better. Second question: I was running several batch jobs the other day and it took 10 hours to complete. I raised the priory level as high as I can. But it was only using 25% to 30% of the CPU. Why is this? Any help would be appreicated Thank,

Please take a look at the Guide to OpenVMS Performance Management. 1: AUTOGEN with FEEDBACK will tend to adjust parameters to meet the typical load -- remember to save the FEEDBACK during SHUTDOWN. 2: The batch job was either not requiring the CPU time available to it as it was blocked by another resource, or there was contention for the available CPU time, or both. (Process priority adjusts the operation of the process scheduler, but it has little or no effect on a number of other system constraints and performance limits that are present on the typical system.) | |||||
