EQA9949S or EQA9949I TCB SVC Screening already active and NOOVERRIDE is specified by EQAOPTS.

Explanation
SVC Screening is in use by another product and SVC Screening CONFLICT=NOOVERRIDE is specified by
EQAOPTS. Handling of non-Language Environment® events is
not available. Debugging of non-Language
Environment
programs will be restricted in this z/OS® Debugger
session.

System action
The z/OS Debugger was invoked with an EQAOPTS
options module that specified CONFLICT=NOOVERRIDE. z/OS Debugger will not intercept non-Language
Environment events and, therefore debugging of
no-Language
Environment programs will be
limited.

Programmer response
If you do not need to debug non-Language
Environment programs or to intercept non-Language
Environment events, no action is required.
Otherwise, you must terminate the prior use of SVC SCREENING (TCBSVCS, TCBSVCSP, TCBSVCA2) before
starting z/OS Debugger or have your installer
provide an EQAOPTS that specified CONFLICT=OVERRIDE. CONFLICT=OVERRIDE allow z/OS Debugger to save and restore the previous use of SVC
SCREENING (TCBSVCS, TCBSVCSP, TCBSVCA2).
