Supported Control Blocks

Control blocks that are natively supported by CBXP.

 

CBXP only supports extracting fields from System-Level Control Blocks that are Documented Programming Interfaces in the z/OS MVS Data Areas documentation.

 

Since CBXP runs in Problem State, only Non-Fetch Protected control block data can be extracted from Live Memory (storage). Also, access to control block data is NOT Serialezd, meaning that CBXP may occasionally extract control block data that is Malformed or otherwise NOT Valid.

 

CBXP currently supports extracting the following System-Level Control Blocks from Live Memory (storage).

 

• PSA
• CVT
• ECVT
• ASVT
• ASCB
