Index Build - IMS Index Builder
Support for HDAM, HIDAM, PHDAM, PHIDAM, and HISAM– Secondary indexes with non-unique keys– Shared Secondary Indexes
Integrated with Database Recovery Facility Recovery Functions:
•Rebuild Primary and Secondary Indexes using scan HALDB Support
—Support for creating the HALDB ILDS where input is based on a scan of the physical HALDB partitions without using the existing ILDS.
—Ability to rebuild selected PSINDEX partitions. —Support for using PSE (Partition Selection Exits) when rebuilding PSINDEXes.
• Integrated IDCAMS for Index Delete/Define

IMS Performance Analyzer
IMS Performance Analyzer remains the premier tool for:– Service Levels and capacity planning– Response time analysis– Monitoring enterprise-wide indicators that can adversely affect IMS
performance
Extracts data from the logs, monitor, IMS Connect
100’s of fields can be summarized and analyzed.
IMS PA can use its forms-based reporting to identify specific processing deficiencies.

Some unique reporting improvements
Cold start analysis takes the IMS log and tell you what would be lost in the event of a cold start
– Input messages (transactions) that would be discarded– Incomplete units-of-work with database changes and ESAF connections
Gap analysis identifies periods of time where log records are not being cut, potentially highlighting an external system event that may have caused IMS to slow down.
Form improvements:– Analyse service levels with distributions. For example, request the percentage of
transactions with response time that exceeded the allowable threshold– Profile database updates and ESAF activity by transaction

IMS Problem Investigator
Analysis of IMS event data can help identify problematic applications and identify system performance issues.
IMS Problem Investigator provides an ISPF interface and batch reporting capabilities that enable the investigator to interactively navigate, investigate, and analyze:
– IMS log– IMS / DB monitor records, – IMS Common Queue Server (CQS) log records, – IMS Connect event data, – SMF records– Omegamon TRF log and extract, – DB2 log, – Websphere MQ log extract.
Key Features include:– Browse, analyze, and interpret logs– Gain an end-to-end picture of transactions in the Sysplex.– Understand IMS log record with detailed field description and global fields.
The TX line action will connect records associated with the same transaction across all logs.
IMS Problem Investigator complements IMS Performance Analyzer for enhanced log analysis and reporting.

Modern IMS transactions affect multiple subsystems
Information about these transactions is recorded in even more sources
IMS PI provides a unified logical view of transactions spanning all these systems
