Log record source processing
When syntax checking is complete, Log Analyzer builds a list of sources that contain the log records to be analyzed. These sources can include:
- System log data sets (SLDSs)
- Online log data sets (OLDSs)
- Log Analyzer extract data sets (containing log records that were extracted from log sources in a previous execution of Log Analyzer)
- Extract log data sets that were created by a third-party utility (containing IMS log records)
- Logs containing DB2 log records
- Journals containing IMS Connect information from the BMC Energizer for IMS Connect product
- Extract files that contain log data from an IBM WebSphere for MQ (formerly known as IBM MQSeries) environment
To identify the log record sources to be processed, use either of the following techniques:
Implicit specification
To use implicit specification, you omit specific log record sources from the control statements. Log Analyzer allocates log record sources from entries in the IMS RECON. Log Analyzer can identify the RECON data set names from IMS dynamic allocation (MDA) members, or you can provide RECON data set names with a control statement. This technique is valid for SLDSs and OLDSs.
If you want to use implicit specification for DB2 logs, you omit specific DB2 log data set names and specify one or more DB2 bootstrap data sets. This technique is valid for DB2 logs.
You can also use implicit specification for Energizer journals. Log Analyzer can determine the journals to use by searching for a specified data set name prefix in the system catalog and using journals that match the time range of the analysis.
Explicit specification
To use explicit specification, you provide the data set name of the source with a control statement. This technique is valid for SLDSs, OLDSs, extract data sets, Energizer journals, DB2 logs, and WebSphere for MQ extract files.
