If you have specified LogToFile=YES, then LogGDG allows you to specify whether the log data sets will be 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.LOG (or LogHLQ.LOG if you choose to use LogHLQ). YES and NO are the only valid values.
Default: NO.
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 will only be created if LogToFile=YES is specified.
If this parameter is not specified, the value that you specify for HLQ on the CONFIG BASIC statement will be used.
Default: none.
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 will be closed and a new log data set will be allocated.
Default: 15.
Specifies whether you want log data to be written to permanent data sets. YES and NO are the only valid values.
Default: NO.
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.
