The values for the OPTIONS parameter for the CTnGRSxx parmlib member
and reply for a TRACE command are listed below. The sub-options on
the CONTROL, REQUEST, MONITOR, SIGNAL and FLOW, allow you to refine
the set of events traced for the major option. When you select the
major option, all events pertaining to that option are traced. However,
you can select one or more of the sub-options instead of the major
option and thus limit the trace to only those events included in the
sub-options specified. A major option, such as MONITOR, and all of
its sub-options (in this case MONITOR0, MONITOR1, and MONITOR2 through
MONITORF) is referred to as an option group. In alphabetical order
the values for the OPTIONS parameter are:
- CONTROL
- Traces unusual events and events related to the establishment,
modification, or termination of the control structure needed for processing
such as:
- Dynamic RNL changes
- Error events
- XCF services used when setting up for processing
When you specify CONTROL, all of the following sub-options are
traced. - CONTROL0
- Traces dynamic RNL changes only.
- CONTROL1
- Traces events related to the establishment of or termination of
membership in the global resource serialization group connection to
the global resource serialization coupling facility structures.
- CONTROL2
- Traces global resource serialization recovery processing only.
- CONTROL3
- Traces global resource serialization resource manager events for
abnormal task and ASID termination only.
- CONTROL4-CONTROLE
- Reserved for IBM® use.
- CONTROLF
- Traces all other unusual events not included in sub-options CONTROL0
through CONTROL3.
- FLOW
- Traces the flow of control from one entry point to another.
- FLOW0
- Traces GRS Star system server processing only.
- FLOW1
- Traces GQSCAN processing only.
- FLOW2
- Traces cross-system communications processing only.
- FLOW3
- Traces command processing only.
- FLOW4
- Traces storage manager services only.
- FLOW5
- Traces coupling facility processing only.
- FLOW6
- Traces initialization processing only.
- FLOW7
- Traces contention monitor processing only.
- FLOW8
- Traces general ENQ/DEQ processing only.
- FLOW9
- Traces entry to GQSCAN/ISGQUERY only.
- FLOWA
- Traces GRS Latch Manager processing only.
- FLOWB-FLOWD
- Reserved for IBM use.
- FLOWE
- Activates extended tracing for the GRS Storage Manager. Do not
turn on this option without direction from IBM Service.
- FLOWF
- Reserved for IBM use.
- Monitor
- Traces events for selected global resource serialization invocations
of monitoring and communication services provided by other components.
- MONITOR0
- Traces use of XES services.
- MONITOR1
- Traces use of XCF services.
- MONITOR2-MONITORF
- Reserved for IBM use.
- REQUEST
- Traces events for global ENQ, DEQ, GQSCAN, and RESERVE macro requests,
and GRS command processing.
- REQUEST0
- Traces ENQ/RESERVE requests only.
- REQUEST1
- Traces DEQ requests only.
- REQUEST2
- Traces GQSCAN only.
- REQUEST3
- Traces IXLLOCK only.
- REQUEST4
- Traces command processing only.
- REQUEST5
- Traces lock structure (ISGLOCK) rebuild processing only.
- REQUEST6-REQUESTF
- Reserved for IBM use.
- RSA
- Traces events for RSA control information.
- SIGNAL
- Traces events for selected global resource serialization invocations
of cross-system coupling facility (XCF) signalling service processing.
- SIGNAL0
- Traces migration signals only.
- SIGNAL1
- Traces GQSCAN signals only.
- SIGNAL2
- Traces ENQ/DEQ signals, including RNL change signals only.
- SIGNAL3
- Traces contention monitor signals only.
- SIGNAL4-SIGNALF
- Reserved for IBM use.
