MAT DB – SQLite support
It has been known for some time now that MAT provides additional ways of storage to the traditional MDS (Monitor Dataset Sets)) in the form of MAT Database (MAT DB). Until now, users could have used the MAT DB option realized via Datacom AD or DB. We are further simplifying and expanding the envelope with the support of SQLite DB.
Why use MAT DB in the first place?
MAT DB allows you to utilize MAT REST APIs and ZOWE CLIs to flexibly work with the measurement data based on your distinct needs.
What are the benefits of using SQLite for MAT DB?
Be sure to check out a short video introducing this functionality.

FRS - Feature Registration Service
Broadcom mainframe products that deliver enhancements using Continuous Delivery (CD) such as MAT can use the Common Components and Services (CCS) Feature Registration Service (FRS) to register themselves with the IBM Function Registry for z/OS enabling you to have more insights of:
- The running Broadcom mainframe products that have been registered through the FRS
- The features of those products, include:
- The feature state (enabled or disabled)
- How often the feature was used (if the product calculates feature usage)
- The maintenance levels of those products
You can use the following methods to view the registry information:
Performance Management Version 16.0 or higher
Displays detailed information about a single product. You must have a SYSVIEW license to use this method.
- IBM FXEPRINT batch utility
Displays detailed information about all registered Broadcom mainframe products.
Displays the feature enablement status for a single product.

CICS global user exits enabled for Threadsafe
Mainframe Application Tuner uses the following CTS Global User Exits:
XPCFTCH - Before an application program is given control.
XPCREQC - After a LINK request has been completed.
XMNOUT - Before a record is to be written to SMF.
XSTOUT - Before a statistics record is written to SMF.
With this enhancement, the user has the choice to install these exits in either Quasi-Reentrant mode or Threadsafe mode.
Using Quasi-Reentrant (QR) mode requires that programs run single-threaded on the CTS QR task control block (TCB). However, in the CTS Open Transaction Environment, when programs are defined to CTS as threadsafe, they can run concurrently on open TCBs. Using Threadsafe may, depending on the user's application workload, reduce TCB switching in CTS = improving CICS performance.
To enable either choice you execute the MAT customization step 10.
For more information, see the updated Define CICS Support article in MAT documentation.
This enhancement is available via PTFs LU08006 LU03057
