Automatic conversion and archiving process on z/OS systems
This section contains information on the automatic conversion and archiving process that takes place on z/OS systems.
When you customized the IBM Tivoli Monitoring environment, you were given the opportunity to specify the EXTRACT option for maintenance. Specification of the EXTRACT option ensures that scheduling of the process to convert and archive information stored in your history data tables is automatic. No further action on your part is required. As applications write historical data to the history data tables, the persistent data store detects when a given data set is full, launches the KPDXTRA process to copy the data set, and notifies the Tivoli Enterprise Monitoring Server that the data set can be used again to receive historical information. Additional information about the persistent data store can be found in IBM Tivoli Management Services on z/OS: Configuring the Tivoli Enterprise Monitoring Server on z/OS.
An alternative to the automatic scheduling of conversion is manually issuing the command to convert the historical data files.
The KPDXTRA process currently does not support UTF8 columns.
- Convert files using the KPDXTRA program
The conversion program, KPDXTRA, is called by the persistent data store maintenance procedures when the EXTRACT option is specified for maintenance. This program reads a data set containing the collected historical data and writes out two files for every table that has data collected for it. The processing of this data does not interfere with the continuous collection being performed.
- Attribute formatting
Some attributes must be formatted for display purposes. For example, floating point numbers that specify a certain number of precision digits to be printed to the left of a decimal point. These display formatting considerations are specified in product attribute files.
- About KPDXTRA
KPDXTRA program runs in the batch environment as part of the maintenance procedures. It is capable of taking a parameter that allows the default column separator to be changed. The z/OS JCL syntax for executing this command is:
- DD names required to be allocated for KPDXTRA
The following is a summary of the DD names that must be allocated for the KPDXTRA program. Refer to the sample JCL in the Sample Libraries distributed with the product for additional information.
- KPDXTRA parameters
The following table specifies the parameters of KPDXTRA, along with their default values and descriptions.
- KPDXTRA program messages
These messages can be found in the RKPDOUT sysout logs created by the execution of the maintenance procedures:
