Modeling the Db2 logging environment

This section describes how to model the Db2 logging environment.

About the logging environment modeling tool

The BMC AMI Recovery Manager logging environment modeling tool allows you to examine and view different logging scenarios for a selected Db2 subsystem in order to optimize the amount of DASD space required by the archive logs.

In addition, you can display active log information and archive log information. By making use of the logging environment modeling tool’s optimization capabilities, you can dramatically reduce the amount of DASD space required by your logging environment.

The logging environment modeling tool has the following features:

  • Displays current logging environment statistics, including:
    • Expected compression ratio if PACLOG is used
    • Days of log data recorded in the BSDS
    • Hours of log required on DASD
    • Highest logging rate
    • Active log size in cylinders
    • Number of active log pairs
    • Number of entries in BSDS
    • Hours of archive 2 on DASD
    • Hours of archive 1 on DASD
    • Total cylinders required by all logging resources
  • Displays information regarding the active logs, including:
    • Total cylinders required
    • Average number of hours in each log
    • Minimum number of hours in each log
    • Start and end times of each log
  • Displays information regarding the archive logs, including:
    • ARCHLOG1 details
    • ARCHLOG2 details
    • Audit details regarding archive copy synchronization

Important

BMC AMI Recovery Manager fully supports the maximum number of active logs (93) and archive logs (10,000) available in Db2.

All active logs can be displayed using the online interface. For performance reasons, only the most recent 100 archive logs are displayed using the online interface. All logs can be processed using the batch programs ARMBARC, ARMBSRR, ARMBEOL, and ARMBCRC.
