Specifying the IMS Queue Control Facility trace table types

To trace processing within the IMS Queue Control Facility control address space, a set of trace table types are provided. These IMS Queue Control Facility trace table types are present only in an IMS Queue Control Facility control address space.

TRCLEV statements specifying a component of IMS Queue Control Facility are ignored for any other address space type.

*

Specifying a type of * enables you to set the default trace level and optionally, the default number of pages per trace table for all of the IMS Queue Control Facility-defined trace table types. If you use the * type, make sure that the * type is the first TRCLEV statement for IMS Queue Control Facility-defined trace table types in your PROCLIB member. You can then code additional TRCLEV statements for specific IMS Queue Control Facility types to selectively override the defaults.

Recommendation: Code a TRCLEV statement with a type of * for IMS Queue Control Facility traces and also specify a minimum level of LOW as your first TRCLEV statement for IMS Queue Control Facility-defined trace table types. Using this coding scheme ensures that tracing is done for all IMS Queue Control Facility trace tables. Using this coding scheme also ensures that any new trace table types that are added in the future will be turned on in your system, even if you have not modified your BPE configuration parameter PROCLIB member to explicitly add a TRCLEV statement.

ERR

The ERR trace table traces error events within an IMS Queue Control Facility address space. The default number of pages for this table is 4.

Restriction: You cannot set the level for the ERR trace table. BPE forces the level to HIGH to ensure that error diagnostics are captured. Any level that you specify for the ERR trace table is ignored. You can, however, specify the number of pages for the ERR trace table on the TRCLEV statement.

INI

The INI trace table traces events that are related to IMS Queue Control Facility initialization processing in the IMS Queue Control Facility server address space. The default number of pages for this table is 4.

MST

The MST trace table traces events that are related to IMS Queue Control Facility master control service processing in the IMS Queue Control Facility server address space. The default number of pages for this table is 4.

CSV

The CSV trace table traces events that are related to IMS Queue Control Facility common service processing in the IMS Queue Control Facility server address space. The default number of pages for this table is 4.

CVC

The CVC trace table traces events that are related to IMS Queue Control Facility client conversation processing in the IMS Queue Control Facility server address space. The default number of pages for this table is 4.

REQ

The REQ trace table traces events that are related to IMS Queue Control Facility client request processing in the IMS Queue Control Facility server address space. The default number of pages for this table is 4.

RSP

The RSP trace table traces events that are related to the response from IMS Queue Control Facility extensions. The default number of pages for this table is 4.

SAF

The SAF trace table traces events that are related to the SAF manager function during IMS Queue Control Facility server address space. The default number of pages for this table is 4.

CMD

The CMD trace table traces events that are related to the command processor during the IMS Queue Control Facility server address space. The default number of pages for this table is 4.

SCI

The SCI trace table traces message activity between the IMS Queue Control Facility server and any active IMS Queue Control Facility clients that request or respond to manipulate the IMS message queues. SCI messages are used to transmit control information from the IMS Queue Control Facility client and message queues output from IMS systems to the IMS Queue Control Facility server address space. The default number of pages for this table is 4.
