The AutoScope functions are a set of tools for the CA Datacom/DB environment that are based on a statistics methodology. They use standard supported CA Datacom APIs to collect information from the CA Datacom Dynamic System Tables and present that information in a usable form.
The purpose of this guide is to provide the user with a set of basic principles and examples for how to use the AutoScope tools.
All of the AutoScope executable functions are performed using the standard CA Datacom/DB DBUTLTY batch utility. For detailed information about the execution and use of each of the DBUTLTY functions, see the CA Datacom/DB DBUTLTY User Guide.
You can use the AutoScope tools and information to help you in your work on the following tasks:
The following are the AutoScope functions:
Extracts information from selected Dynamic System Tables (DSTs) in snapshots and records these snapshots in Snapshot rows in tables in a permanent database. Since the counters in the DSTs continually increase as resources are used, each Snapshot will represent the total resources consumed since MUF start-up. Users can run reports to determine what Snapshots have been collected, then when ready, process the Snapshots into Deltas. A Delta is calculated by taking two Snapshots from the same MUF instance and subtracting the earlier one from the later one to create the difference (or Delta). Users then analyze the Delta results to determine performance metrics and make tuning decisions. AutoCollect operations are typically focused on a given MUF. In other words, while you can use AutoCollect to collect data on multiple MUFs, the built-in data analysis functions are only used against one MUF at a time.
To use AutoCollect, you must have an active MUF environment with the AutoCollect databases (default 1019 and 1020) defined. For information about how to create these databases in a new or upgraded CA Datacom r12 system, see the CA Datacom Installation and Maintenance Guide.
Extracts task activity information in snapshots from the Dynamic System Table MUF_ACTIVE_TASKS, from one or more MUFs on a given LPAR and records these snapshots in a permanent database so you can run reports and analyze the results. AutoStatus information is typically used to track task activity on one or more MUFs looking for possible interactions, locking problems, and so on.
To use AutoStatus, you must have an active MUF environment with the AutoStatus database (default 1018) defined. For information about how to create this database in a new or upgraded CA Datacom r12 system, see the CA Datacom Installation and Maintenance Guide.
Extracts a single informational snapshot from Dynamic System Tables and combines it with other available information to provide the user with a simple way to gather multi-user environmental information such as MUF Start-UP options, system statistics, task information, and so forth and produce a report with the information. In addition to the report, an optional sequential file can be created that can be sent (using FTP) to the CA Support staff to help in problem debugging. AutoInfo will provide the user a simple way to document the MUF environment set-up and statistics since the MUF was last enabled. To get the full use AutoInfo, the user must have the Dynamic System Tables activated in the MUF.
