Using trace in CICSPlex SM

All CICSPlex® SM address space (CMAS) and managed application system (MAS) components provide trace data.

Tracing in a CMAS
The CICS® internal trace facilities must always be active in a CMAS.
Tracing CMAS components
CMAS component tracing is provided for the use of IBM® service personnel. CMAS trace settings are normally not active. Activating tracing may have an adverse effect on performance.
Tracing in a MAS
The CICS trace facilities do not have to be active in a MAS.
Tracing MAS components
MAS component tracing is provided for the use of IBM service personnel. CMAS trace settings are normally not active. Activating tracing may have an adverse effect on performance.
Tracing in a WUI
Use of tracing in a CICSPlex SM Web User Interface (WUI) can help to diagnose any problems encountered while using the interface.
Types and levels of tracing
Each CMAS and MAS component can make use of three types and up to 32 levels of tracing.
Controlling the amount of tracing in a CMAS or MAS
During normal CMAS and MAS processing all the standard and special trace levels (levels 1–32) are usually disabled. Exception tracing is always active and cannot be disabled.
Formatting CMAS and MAS trace entries
The CICSPlex SM trace format utility, EYU9XZUT, formats the raw trace records produced for a CMAS or MAS.
Interpreting CMAS and MAS trace entries
A single CMAS or MAS trace can produce multiple records. Each record consists of a standard header followed by up to 3900 bytes of unique trace data.
Web User Interface trace services
The CICSPlex SM Web User Interface (WUI) provides a trace service to help diagnose any problems encountered while using the interface.
