    New feature: Connect MAT CLI output to the listing of source code in VSCODE editor

    This feature emphasizes the user experience of CA MAT Performance Benchmarking and the modern developer approach, bringing an ability to the developer to see the top consumers from the analysis report and correlate them on respective code statements within IDE (VSCODE) with a single click.  


    Utilizing a new CLI parameter --listing true or listing=true for REST API call (see Fig. 1 & 2), during invocation, related Endevor SCM footprint is stored in CA MAT DB.

    Fig. 1 & 2 – REST API invoke call with listing parameter & CLI invoke command with listing parameter

    This information can be later fetched during analysis time. Referred by the same parameter used within CODEVIEW CLI or REST call.

    e.g.  zowe mat monitor  codeview histogram --mon_num 63 --module SC630LE --csect SC630LE --top 2 --listing true

    With such users can click the displayed listing path information e.g "C:\Users…\listing\SC630LE.cbl:342:30" to be directly pointed to the appropriate line/statement within the VSCODE IDE (see Fig. 3).

    Fig. 3 – Easily clickable correlation to the editor directly from the CLI output.


    This VSCODE related functionality is available to MAT users for ASM, COBOL, C, and C++ languages.


    To find more information please refer to CA MAT documentation here:


    This enhancement is available via PTF #LU01297

    New Feature: Support of DB2 Shared Subsystems

     This addition to CA MAT v12 allows MAT users to gather specific DB2 Shared Subsystem metrics and use them to identify tuning opportunities. While measuring MAT can now collect both global and local buffer pool information and DB2 locking information and aggregate related information per SQL where applicable.


    Hands-on users will experience new fields under DB2View that can be enabled or disabled using advanced panel command CUST and two new primary commands on DB2View – LOCK and POOL (see Fig. 4)

    Where POOL command takes a user to the summarized PoolView panel where it is easy to drill down to detailed information about a specific buffer. (see Fig. 5)

    Fig. 4 – NEW DB2 Shared Subsystem information present on DB2View

    Fig. 5 – NEW Buffer pool information details from PoolView

    And LOCK primary command displays directly LOCK information for both local and global locking data (see Fig. 6).

    To find more about this feature please refer to the following MAT documentation topics:

    This functionality is available via enhancement PTFs #LU01600 and #LU01599.
