CA Index Expert Modernization Guide

CA Index Expert automated the analysis of DB2 indexes to improve database performance. It analyzed SQL and DB2 processing statistics to recommend optimal indexing strategies.

The tool analyzed SQL workload and DB2 runtime statistics to identify inefficient queries and recommend appropriate indexes. It considered factors such as data distribution, query frequency, and index maintenance costs.

The tool provided reports detailing the potential performance improvements from implementing the recommended indexes. These reports included estimates of CPU savings, I/O reduction, and overall query response time improvements.

CA Index Expert analyzed DB2 catalog statistics, EXPLAIN output, and dynamic SQL cache information. It used this data to understand query access paths and identify missing or inefficient indexes.

The tool likely used a combination of SQL queries against the DB2 catalog tables and proprietary algorithms to analyze the data. The exact algorithms are not publicly documented.

While specific API details are unavailable, CA Index Expert likely interacted with DB2 through standard interfaces like JDBC or ODBC to retrieve catalog information and execute EXPLAIN statements.

By recommending optimal indexes, CA Index Expert aimed to reduce CPU consumption, I/O operations, and overall query execution time. This translated to lower infrastructure costs and improved application performance.

Improved query performance led to faster transaction processing, reduced application bottlenecks, and enhanced user experience. This was particularly important for high-volume OLTP systems.

By automating the index analysis process, CA Index Expert reduced the need for manual DBA effort. This freed up DBAs to focus on other critical tasks such as database design and performance tuning.

As a tool focused on index analysis, CA Index Expert did not directly manage user authentication or authorization. It relied on the underlying DB2 security mechanisms for access control.

CA Index Expert likely logged its activities, such as index recommendations and report generation, to a log file. However, specific details on the audit logging capabilities are unavailable.

Since CA Index Expert primarily read DB2 catalog data, it did not require extensive data encryption capabilities. The security of the DB2 data itself was managed by DB2's native security features.

CA Index Expert likely required access to DB2 catalog tables and the ability to execute EXPLAIN statements. This required appropriate DB2 privileges for the user running the tool.

The tool likely generated reports in a standard format such as PDF or HTML. These reports could be distributed to DBAs and application developers for review and implementation.

Monitoring the tool's performance involved checking the log files for errors and ensuring that it had sufficient resources to access the DB2 catalog and execute EXPLAIN statements.
