Fields
Thread identifier: This information
identifies the thread to which the information in this panel applies.
- Plan
- The DB2 plan name of the active thread.
- Connid
- The DB2 connection identifier of the active thread.
- Corrid
- The DB2 correlation identifier of the active thread. If the correlation is not set, N/A is displayed.
- Authid
- The DB2 authorization identifier of the active thread.
- Attach
- Depending on the type of connection, the appropriate information is displayed.
- Attach information is displayed only if the thread is a distributed allied thread (not for distributed database access threads).
- Connection Type
- Batch
- The MVS™ jobname and ASID.Note: For threads from remote DB2, the MVS job name is N/A.
- CICS®
- The CICS jobname, task
name, task number, terminal ID, and thread type. The thread type is:
- Pool
- The thread in use is a pool thread.
- Enty
- The thread in use is a nonprotected entry thread.
- Prot
- The thread in use is a protected thread. Protected threads are defined in an RCT entry definition using the THRDS operand.
- IMS™
- The IMS region number, transaction name, region name, and terminal ID (LTERM).
- RRSAF
- The MVS job name and ASID.Note: For threads from remote DB2, the MVS job name is N/A.
- System
- The originating DB2 job name and the resource manager that is the source of the thread. An additional line below the Attach line identifies the user thread, if any, being served by the system thread.
- TSO
- The TSO user ID and region ASID.
- Utility
- No additional information.
- DB2
- The DB2 subsystem identifier.
- MVS
- The MVS system identifier.
- ORIGAUTH
- The original (primary) DB2 authorization identifier of the thread. This field displays only when the original identifier is different from the Authid.
Package
identifier: This information identifies the package to which the
information in this panel applies.
Distributed
thread identifier: The following fields are displayed if the thread
has a distributed relationship with a remote DB2 subsystem.
- Type
- The distributed thread type.
- Distributed Allied
- A requesting thread; one that has issued an SQL call to a remote DB2 location.
- Database Access
- A responding thread; one that is serving a remote DB2 location by responding to an SQL call.
- DB2=
- The DB2 subsystem ID, indicating the member of the data sharing group of this thread.
- Luwid
- This value consists of two parts: the logical unit
of work ID (luw-id) and a token. The token can be used in place of
the luw-id in any DB2 command
that accepts luw-id as input. Format:
luw-id=tokenThe luw-id consists of the network name, the originating VTAM® LUNAME, and a unique identifier (separated by periods). Thus, the Luwid field displays data like in the following example:
USCACO01.O2D22A.A1FE8E04B9D4=8 - System
- The originating DB2 job name and the resource manager that is the source of the thread. An additional line below the Attach line identifies the user thread, if any, being served by the system thread.
Package information:
- Program
- The program name for which data is reported. Up to 18 characters of the package name are returned.
- Type
- The program type can be:
- PACKAGE
- DBRM
- PACKAGE-STORPROC, which means that the program is a package that was loaded by a stored procedure.
- Location
- The name of the location where the package is executed. For remote packages, times displayed represent the time spent locally to execute the remote package.
- Token
- The consistency token.
- Collection
- The package collection ID. This field is displayed only if the program type is PACKAGE.
- SQL Request Count
- The number of SQL statements issued. All DCL, DDL, and DML SQL statements as well as some Statistic Counters from DSNDQXST are included. COMMIT and ROLLBACK/ABORT are not included.
In-DB2 Times: In-DB2
times require an Accounting trace class 7. If this trace is not active, N/A is
displayed.
- In-DB2 elapsed time
- The elapsed time while processing this package or DBRM:
- Total
- The total time the thread spends processing this package or DBRM.
- Current
- The total time spent processing the currently active SQL statement.
- In-DB2 CPU time
- The CPU time spent processing this package or DBRM.
- Total
- The total time the thread spends processing this package or DBRM.
- Current
- The total time spent processing the currently active SQL statement.
