CA IDMS/DB Journal Reports—JREPORTS › Uses for Journal Reports

Uses for Journal Reports

Journal reports produce statistics that can be used to monitor CA IDMS/DB database and DC/UCF system performance. As a DBA, journal statistics allow you to monitor the following performance features for each program that accesses the database:

• Database page access statistics, such as the number of pages written, read, and requested by each program and the number of records requested and made current of the transaction
• CALC and VIA overflow statistics, such as the number of CALC records stored on pages other than the target page
• Variable-length record statistics, such as the number of variable-length record fragments stored on pages other than the target page
• Area usage statistics, such as the name and usage modes of areas accessed by each application program

Reports Help You Monitor Performance

By running journal reports frequently, a DBA can monitor trends in database and system performance.

Other Reporting Facilities

Other tools available to the DBA are the Database Analysis Utility (IDMSDBAN) and the BACKUP utility.
