Enabling Restart Support for IDMS Applications with Smart/RESTART

By Aysen Svoboda
Smart/RESTART, with its z/OS Resource Recovery Services (RRS) integration, now offers basic support for IDMS applications that run on an RRS-enabled IDMS Central Version (CV). This blog post aims to explain how to make IDMS applications restart-enabled by leveraging Smart/RESTART. While DB2 is still required for synchronization control, the IDMS application itself doesn't need any DB2 references or coding. The DB2 repository access is implicit and driven through RRS API calls for commits or rollbacks. IDMS-Only Scenario: To restart-enable an IDMS application, it must be designed around the concept of a Unit of Work (UOW) where the database objects ...

ACM Builds Without Generates

By Joseph Walther
Introduction Some Endevor sites have existed for years without the full benefit of the Automated Configuration Manager (ACM). Perhaps time constraints or other pressing demands, years or decades ago, led to shortcuts that rendered an incomplete ACM. This blog will help such sites quickly and safely build their Automated Configuration data to gain back features that had been lost to them, including: Using the ACM Query Facility to quickly perform "where-used" or “impact analysis” queries against ACM component data. Identifying a complete list of application components for scoring, using tools such as SonarQube. Using the AutoGen functionality ...

Improving XCOM Data Transport transfers with TLSv1.3

By Austin Willoughby
Improving XCOM Data Transport transfers with TLSv1.3 You can use a network service proxy to incorporate improved TLS features into your XCOM Data Transport transfers. This blog will show an example of using XCOM Data Transport between z/OS and Linux (RHEL 8.6) to create transfers that are secured between the systems using TLSv1.3. While the example focuses on Linux transfers, the same concepts may be applied to other environments (e.g. Windows) where you have a TLSv1.3 capable network service proxy. Sending data to z/OS Your XCOM Data Transport z/OS started task will be the server in this first scenario, listening for suitable remote connections. ...

NEW: CA Log Analyzer Gains I/O Saving Option

By Jakub Hofman
We are pleased to announce that we released new Bypass Extract feature in CA Log Analyzer for Db2 for z/OS (PLA) that lets you avoid this unnecessary reading and writing. Thus, you save I/O operations, CPU, and Elapsed Time. PLA uses the extract file to store filtered data from the Db2 log. The extract file is a pair of datasets. You can use permanent datasets to generate different reports over the same log range or for future auditing purposes (the extract file is much smaller than Db2 log, since it contains required log data only). Often, you do not need the extract file and you are using temporal datasets. But PLA still writes all the filtered data into the ...
