CONFIG LOGFILE statement

Logging records activity within the Application Performance Analyzer Listener started task. Log data is always written to SYSOUT, but you have the option of also writing this data to log data sets. LOGFILE settings allow you manage these data sets. The following settings might be specified:
LogGDG
Optional. If you have specified LogToFile=YES, then LogGDG allows you to specify whether the log data sets are allocated as GDGs or normal sequential data sets. If you specify LogGDG=YES, you must first create the Generation Data Group Index using an index name of yourhlq.LLG (or LogHLQ.LLG if you choose to use LogHLQ). YES and NO are the only valid values.

Default: NO.

Note: A GDG log file cannot be shared by multiple instances of Application Performance Analyzer Listener. A second started task with the same GDG log file fails on start up with messages IKJ56225I and CAZL034S. A unique GDG log file must be defined for each instance of Application Performance Analyzer Listener.
LogHLQ
Specifies the high-level qualifier to be used when creating log data sets. LogHLQ must comply with the JCL rule for specifying a data set name. It can be no more than 17 characters long. A data set is only created if LogToFile=YES is specified.

If this parameter is not specified, the value that you specify for HLQ on the CONFIG BASIC statement is used.

Default: None.

LogPRIM
Optional. If you have specified LogToFile=YES, then LogPRIM allows you to specify the size of each log data set that is allocated. No secondary specification is permitted. Therefore, when the log data set has filled, it is closed and a new log data set is allocated.

Default: 15.

LogToFile
Optional. Specifies whether you want log data to be written to permanent data sets. YES and NO are the only valid values.

Default: NO.

Note: It is recommended that LogToFile be set to YES. The log can be used to help diagnose problems.
LogUNIT
Optional. If you have specified LogToFile=YES, then LogUNIT allows you to specify whether you want the log data set to be allocated in Tracks or Cylinders. T and C are the only valid values.

Default: T.
