Administration of the Central Component › Batch Jobs

Batch Jobs

To reduce the workload of the Application Performance Management Team, Performance Management Assistant can automatically perform the following functions in batch:

• Measure runaway job steps and issue alerts
• Measure new or modified programs
• Interpret the measurements based on user parameters
• Save only important data from the reports created by your measurement tool
• Manage historical data
• Exclude certain job steps or programs from measurement by using the scope of work definitions for Performance Management Assistant and CA Mainframe Application Tuner

The required batch part of the Central Component consists of the following jobs:

• Job APCXJSMF gathers information about job step executions from SMF type 30 (subtype 4) records. Using this information, Performance Management Assistant calculates statistical values for consumed elapsed time and service units and checks if the last job step execution exceeded them. If it finds a runaway, a pending alert is created. Additionally, APCXJSMF checks the defined alert thresholds against the SMF values. If one of the defined thresholds is exceeded by the consumption values, then a pending alert is also created.
• Job APCXJLIB determines which programs have been modified since the last APCXJLIB job execution and in which job steps these programs are called. Performance Management Assistant then creates corresponding pending Alerts.
• Job APCXJINV deletes measurement requests generated during previous cycles from the CA MAT queue and places new CA MAT measurement requests in the CA MAT queue based on the information in your daily run schedule and in the pending Alert list.
• Job APCYJLST evaluates measurement data sets that resulted from generated measurements. Performance Management Assistant saves the resulting measurements if they are of interest or otherwise deletes them.

Additionally, a job is available for reorganization of the VSAM clusters.
