Operations control DB2 console
MainView for DB2 provides several unique features that aid in operations control of DB2:
The DB2 console is a chronological journal log (LOG DISPLAY) of DB2 messages and MainView for DB2 exceptions that allows you to go back in time to analyze earlier problems. From this log, DB2 commands can be issued and the responses viewed. Managing the BBI-SS product address space (PAS) describes how to activate the logging of DB2 messages and the authorization that is required for a user to issue DB2 commands.
Multiple-systems support not only provides immediate user access to multiple DB2 systems on the same CPU but also to any number of DB2s on multiple z/OS systems in local and remote locations.
The windows mode technology also enables Single System Image (SSI) views that can pull together and even summarize data from multiple DB2 subsystems.
This capability increases the span of control and saves time for all users that are managing more than one DB2. For example, a status overview display presents key indicators and exceptions for all DB2s, allowing for a quick check for potential problems. Any set of related DB2s, such as production or test, can be defined as a context for SSI monitoring.
SSI views are even more important in a data sharing environment, because a group of DB2 members that work together can be monitored as a whole. These views not only simplify sysplex management, but also increase understanding of this complex environment.
Using product-defined dynamic contexts, you can group data sharing member targets by their data sharing group name. The product address space (PAS) defines these contexts internally for active data sharing targets. The contexts are maintained for the life of the associated coordinating address space (CAS).
To use these contexts, specify CONTEXT DSG:dsGroup, where dsGroup is the data sharing group name.
- Screens are refreshed through full-screen status and exception displays from all DB2 systems providing dynamic monitoring of multiple DB2s.
- Seamless integration with the MainView AutoOPERATOR product automates both DB2 operation and performance monitoring. Messages can initiate rules to take action, query the MainView for DB2 analyzer displays for additional information, or issue monitor commands. Exception messages can be sent to the z/OS console to interact with other automated operator products.
- Total system status of all monitored values versus site thresholds can be seen at a glance in a graphic display with color support. Potential problems that have not yet resulted in exception conditions can thus be easily detected.
- User access through EXCP assures access even when TSO or VTAM does not respond.
- Security is provided per function and per DB2 system through user profiles and a user exit that controls access to thread activity displays.
