CEMT INQUIRE DB2ENTRY

Description

The entry is identified by the name with which it was defined in CEDA.

The resource signature

You can use this command to display the resource signature fields. You can use these fields to manage resources by capturing details of when the resource was defined, installed, and last changed. For more information, see Auditing resources. The resource signature fields are CHANGEAGENT, CHANGEAGREL, CHANGETIME, CHANGEUSRID, DEFINESOURCE, DEFINETIME, INSTALLAGENT, INSTALLTIME, and INSTALLUSRID. See Summary of the resource signature field values for detailed information about the content of the resource signature fields.

Displayed fields

ACCOUNTREC

Returns the minimum amount of DB2 accounting record required for transactions using this DB2ENTRY. The specified minimum might be exceeded, as described in the following options. The values are as follows:

UOW

The CICS DB2 attachment facility causes an accounting record to be produced for each UOW, assuming that the thread is released at the end of the UOW.

TASK

The CICS DB2 attachment facility causes a minimum of one accounting record for each CICS task to be produced.

A transaction containing multiple UOWs may use a different thread for each of its UOWs (assuming the thread is released at sync point). The result may be an accounting record produced for each UOW.

TXID

The CICS DB2 attachment facility causes an accounting record to be produced when the transid using the thread changes.

This option applies to DB2ENTRY inquiries that are used by more than one transaction ID. Because threads are typically released at sync point, a transaction containing multiple UOWs can use a different thread for each UOW. The result may be that an accounting record is produced for each UOW.

NONE

No accounting records are required for transactions using threads from this DB2ENTRY.

DB2 does, however, produce at least one accounting record for each thread when the thread is ended. Additionally, authorization changes cause accounting records to be produced.

AUTHID

Returns an ID to be used for security checking when using pool threads. If an AUTHID is returned, AUTHTYPE is not applicable.

AUTHTYPE

Returns the type of ID to be used for security checking for threads on this DB2ENTRY. If an AUTHTYPE is returned, AUTHID is blank. The values are as follows:

GROUP

The 8-character user ID and the connected group name are used as the authorization ID. The following table shows how these two values are interpreted by DB2.

IDs passed to DB2	How DB2 interprets values
CICS sign-on user ID (USERID)	Represents the primary DB2 authorization ID.
RACF connected group name	If the RACF list of group options is not active, then DB2 uses the connected group name supplied by the CICS attachment facility as the secondary DB2 authorization ID. If the RACF list of group options is active, DB2 ignores the connected group name supplied by the CICS attachment facility, but the value appears in the DB2 list of secondary DB2 authorization IDs.

If no RACF group ID is available for this user ID, an 8-character field of blanks is passed to DB2 as the group ID.

SIGN

The SIGNID parameter of the DB2CONN is used as the resource authorization ID.

TERM

The terminal identification (four characters padded to eight) is used as an authorization ID. An authorization ID cannot be obtained in this manner if a terminal is not connected with the transaction.

If a transaction is started using a CICS command and has no terminal associated with it, do not use AUTHTYPE(TERM).

TX

The transaction identification (four characters padded to eight) is used as the authorization ID.

OPID

The operator identification associated with the user ID that is associated with the CICS transaction is used as the authorization ID (three characters padded to eight).

USERID

The 8-character user ID associated with the CICS transaction is used as the authorization ID.

When the DB2 sample sign-on exit DSN3@SGN is used with AUTHTYPE(USERID), the exit sends the user ID to DB2 as the primary authorization ID and the RACF group ID to DB2 as the secondary ID. When the sample sign-on exit is used, there is no difference between AUTHTYPE(USERID) and AUTHTYPE(GROUP).

CHANGEAGENT(value)

Displays a value that identifies the agent that made the last change to the resource definition. You cannot use CEMT to filter on some of these values because they are duplicated. The possible values are as follows:

CREATESPI

The resource definition was last changed by an EXEC CICS CREATE command.

CSDAPI

The resource definition was last changed by a CEDA transaction or the programmable interface to DFHEDAP.

CSDBATCH

The resource definition was last changed by a DFHCSDUP job.

DREPAPI

The resource definition was last changed by a CICSPlex SM BAS API command.

CHANGEAGREL(value)

Displays the 4-digit number of the CICS release that was running when the resource definition was last changed.

CHANGETIME(date time)

Displays the date and time when the resource definition was last changed. The format of the date depends on the value that you selected for the DATFORM system initialization parameter for your CICS region. The format of the time is hh:mm:ss.

CHANGEUSRID(value)

Displays the 8-character user ID that ran the change agent.

DEFINESOURCE(value)

Displays the source of the resource definition. The DEFINESOURCE value depends on the CHANGEAGENT option. For details, see Summary of the resource signature field values.

DEFINETIME(date time)

Displays the date and time when the resource was created. The format of the date depends on the value that you selected for the DATFORM system initialization parameter for your CICS region. The format of the time is hh:mm:ss.

DISABLEDACT

Returns a value showing what CICS is to do with new transactions accessing DB2ENTRY when it has been disabled or is disabling. If DISABLEDACT is not specified, and DB2ENTRY is disabled, new requests are routed to the pool by default. The values are as follows:

POOL

The CICS DB2 attachment facility routes the request to the pool. Message DFHDB2072 is sent to the transient data destination specified by MSGQUEUEn on the DB2CONN for each transaction routed to the pool.

ABEND

The CICS DB2 attachment facility stops the transaction.The abend code is AD26.

SQLCODE

An SQLCODE is returned to the application indicating that the DB2ENTRY is disabled.

DROLLBACK

Returns a value showing whether the CICS DB2 attachment should initiate a sync point rollback if a transaction is adversely affected by a deadlock resolution. The values are as follows:

ROLLBACK

The attachment facility issues a sync point rollback before returning control to the application. An SQL return code of -911 is returned to the program.

NOROLLBACK

The attachment facility does not initiate a rollback for this transaction. An SQL return code of -913 is returned to the application.

ENABLESTATUS

Indicates whether the DB2ENTRY can be accessed by applications. The values are as follows:

ENABLED

The DB2ENTRY can be accessed by applications. DB2ENTRY is installed in an ENABLED state.

DISABLED

The DB2ENTRY cannot be accessed by applications.

DISABLING

The DB2ENTRY is in the process of being disabled. New transactions cannot access the DB2ENTRY. Existing transactions using the DB2ENTRY are allowed to complete unless the DB2ENTRY is being disabled with the FORCE option.

INSTALLAGENT(value)

Displays a value that identifies the agent that installed the resource. You cannot use CEMT to filter on some of these values because they are duplicated. The possible values are as follows:

CREATESPI

The resource was installed by an EXEC CICS CREATE command.

CSDAPI

The resource was installed by a CEDA transaction or the programmable interface to DFHEDAP.

GRPLIST

The resource was installed by GRPLIST INSTALL.

INSTALLTIME(date time)

Displays the date and time when the resource was installed. The format of the date depends on the value that you selected for the DATFORM system initialization parameter for your CICS region. The format of the time is hh:mm:ss.

INSTALLUSRID(value)

Displays the 8-character user ID that installed the resource.

PLAN

Returns the name of the plan to be used for this DB2ENTRY. If PLAN is returned, PLANEXITNAME is blank.

PLANEXITNAME

Returns the name of the dynamic plan exit (if any) to be used for this DB2ENTRY. If PLANEXITname is returned, PLAN is blank.

PRIORITY

Returns the priority of the pool thread TCBs relative to the CICS main TCB (QR TCB). The thread TCBs are CICS open L8 TCBs.

HIGH

Thread TCBs have a higher priority than the CICS QR TCB.

EQUAL

Thread TCBs have equal priority with the CICS QR TCB.

LOW

Thread TCBs have a lower priority than the CICS QR TCB.

PROTECTNUM

Returns the maximum number of protected threads allowed for this DB2ENTRY.

PTHREADS

Returns the current number of protected threads for this DB2ENTRY. A protected thread is an inactive thread available for reuse by a new transaction. If no transaction has reused the thread by the time it has been processed by two purge cycles, the thread is ended.

THREADLIMIT

Returns the current maximum number of threads for this DB2ENTRY that the CICS DB2 attachment allows active before requests are made to wait, overflow to the pool, or are rejected. See the Threadwait field.

THREADS

Returns the current number of threads active for this DB2ENTRY.

THREADWAIT

Indicates whether transactions wait for a DB2ENTRY thread to be abended, or overflow to the pool if the number of active DB2ENTRY threads reach the Threadlimit number. The values are as follows:

TWAIT

If all threads are busy, a transaction waits until one becomes available.

NOTWAIT

If any threads are busy, a transaction is stopped with an abend code AD2P.

TPOOL

If all threads are busy, a transaction is diverted to use a pool thread. If the pool is also busy, and NOTWAIT has been specified for the THREADWAIT parameter on the DB2CONN, the transaction is ended with abend code AD3T.
