SVC dump screening

A feature is provided with the CFA transaction that can be used to improve performance when capturing SVC dumps of CICS® regions. The feature, which can be installed or uninstalled using the CFA transaction, provides screening of the SDUMP SVC (SVC 51) to ensure that the SDATA dump options XESDATA and GRSQ are turned off while the dump is being taken.

Note: If you have other tools or products that screen the SDUMP SVC (SVC 51), do not install Z Abend Investigator dump screening - either via the CFA transaction or by theHFZPLTS CICS PLT program. If another screening program is installed when you attempt to install Z Abend Investigator dump screening, the Z Abend Investigator code is not installed and a message is issued.
