Transaction Manager Information

This function can be used to obtain information from an executing Adabas Transaction Manager.


Transaction Manager Information Menu

Start of instruction setTo display the Transaction Manager Information menu

The ID of the transaction manager you are currently working with is displayed on this screen and on most screens in this part of the application. For example,

Manager: 20531.

You can use PF2 to issue ATM operator commands to the transaction manager with which you are working. If you omit the command prefix ATM, SYSATM supplies it for you. For example, if you enter the command NOLOG, it will be changed to ATM NOLOG. The text you enter on the command line is not validated before the command is issued, except to check whether the command will terminate the transaction manager. If you enter the command ATM HALT or ATM END (or simply HALT or END), a window appears asking you to confirm your intention to close down the transaction manager. See section Operator Commands for a complete description of all operator commands.

Select Different Transaction Manager

If your system contains more than one operating system image and Entire Net-Work is being used to connect them, you may wish to work with a transaction manager that is executing in a different operating system image. In this case, select option 0 and enter the ID of the transaction manager in the field New Manager Node.

Note:
Running more than one ID table in the same system with Entire Net-Work providing the connection between users of each ID table is equivalent to executing across different operating system images.

The following information is provided:

Field Description
Transactions

The number of transactions, or branches, processed by this manager appears on the line that begins “Total”. This figure is broken down on the preceding lines into transactions that were controlled only by ATM (“ATM-only”), and transactions that were controlled by an external transaction coordinator, such as the CICS syncpoint manager or RRMS (“Extrn.”).

“Open” indicates the number of transactions, or branches, that are currently open and that involve this transaction manager.

“HWM” indicates the high-water mark for transactions; that is, the highest number of transactions, or branches, that have been in progress at the same time, involving this transaction manager.

Commits This column indicates how many of the transactions, or branches, that this manager has processed were committed. The total is broken down into those that were controlled solely by ATM, and those that were controlled by an external transaction coordinator.
Tran timeout This column indicates how many of the transactions, or branches, that this manager has processed were backed out because the global transaction time limit was exceeded. The total is broken down into those that were controlled solely by ATM, and those that were controlled by an external transaction coordinator.
Heuristic This column indicates how many of the transactions, or branches, that this ATM has processed, have experienced some degree of heuristic termination, either by ATM or by a database. The total is broken down into those that were controlled solely by ATM, and those that were controlled by an external transaction coordinator.

Mark one of the following functions:

Function Description
Stop a transaction

Terminate the transaction for which detail information is being displayed.

Stop all trans in the same service

Terminate the transaction for which detail information is being displayed and all other incomplete transactions belonging to clients in the same address space.

This option can be used, for example, to terminate all transactions belonging to clients in a given CICS region.

When this option is invoked, a console message is issued so that the event can be audited.

Stop all transactions

Terminate all incomplete transactions.

When this option is invoked, a console message is issued so that the event can be audited.

Caution:
If you terminate a transaction branch or a part of a transaction that is controlled by an external transaction coordinator, only the local branch or local part of the transaction is affected. This could compromise the integrity of the global transaction as a whole.

By default, ATM attempts to complete (back out or commit) any incomplete transaction within the specified scope of the “Stop” request, according to its current status. By default, if a transaction is backed out, a pending response code 9 will be retained, either in the manager’s transaction queue or in the pending response code list. ATM will not, by default, attempt to complete a transaction or branch that is controlled by another ATM manager or by an external transaction coordinator if this transaction or branch has reached the prepared state, unless ATM is certain of the intended outcome.

You can optionally increase the severity of the action to be applied to the selected incomplete transactions by marking one of the following options:

Function Description
No rsp 9 for client

If this option is selected, no pending response code will be set for the owner of a transaction which is resolved, even if it was backed out. The transaction will disappear from the manager’s list.

Transfer to STJ

This option causes the same processing as the “No rsp 9” option.

Further, termination is attempted for any selected transaction or branch that is controlled by another ATM manager or an external transaction coordinator.

Additionally, any of the selected transactions or branches that then remain (because they could not be resolved) are copied to the suspect transaction journal (STJ) and removed from the transaction list, without regard to the status of the transaction. Messages are written to the console giving details of the operation.

Caution:
When this option is used, global transaction integrity is likely to be lost. This option is provided for emergency use only.

Display Pending ET Data

Pressing PF6 from the Transaction Details screen will display any pending ET data if the transaction is partially through the commit process.

The ET data is displayed in hexadecimal and character format:

If the list is too long to fit on the display, “More” appears at the foot of the screen. Use PF8 to scroll down the list and PF7 to return to the top of the list.

Delete Pending Response Code

Normally, a pending response code is kept in the manager’s memory, and possibly also in its recovery file, until the manager has an opportunity to return it to the transaction’s owner, or until the owner is known to have disappeared.

For more information, see the section Introduction, Pending Response Codes.

The Display Pending Response Code Details screen provides a facility for deleting the pending response code. To use this facility, display the details of the pending response code that you want to delete, then press PF5 (“Del”). You will be prompted to confirm your intention to delete the pending response code.

Note:
If you use this facility, the pending response code will be removed from the manager’s memory and from the recovery file, so the owner of the transaction will never receive the pending response code. This might mean, for example, that the owning client will never become aware that the previous transaction was backed out.

    The format of the list is identical to that displayed using option 2 (active transactions).

  • Q: quiesce all transactions that involve the selected database

    ATM attempts to complete (commit or back out) any transactions that involve the selected database, depending on the status of the transaction.

    If the transaction manager is managing transaction branches that involve the selected database, it asks the ATMs that own those transactions to complete them (that is, commit them or back them out), as appropriate

    This option does not prevent new transactions from changing the selected database.

DB No.

The normal Database ID.

Manager

The ID of the database’s local ATM.

DTP Indicates whether the database is running DTP=RM (Y) or DTP=NO (N).
Usage The number of open transactions that involve the database.

Displaying Recovery Records and Suspect Transactions

Select code 1 or 2 to list recovery records or browse the suspect transaction journal (STJ). The order in which records are displayed is not significant.

For both options, the resulting list has the following layout; only the subheading differs:

The following information is provided

Item Description
L/R Indicates whether the transaction’s owner is (or was) local to (L) or remote from (R) the transaction manager; that is, whether or not the client is (or was) executing in the same operating system instance.
Communication ID The transaction owner’s Communication ID in hexadecimal format.
Client ID The transaction owner’s Client ID in character format.

For a more detailed display of an item, type D in the C column next to the item and press Enter. The resulting display has the same layout as the Transaction Details screen.

To delete a record from the STJ or the recovery record file, type P (for “purge”) in the C column next to the selected item and press Enter. You are prompted to confirm that the record should be deleted.

Caution:
The purge function is provided for housekeeping of the STJ file. If you use it to delete a record from the recovery record file, you could compromise the integrity of the related global transaction, and results are unpredictable. Therefore, for audit purposes, a console message is issued when a recovery record is deleted.

List Migrated Transaction Records

To list migrated transaction records, enter code 3. If a client executes in an environment in which dynamic transaction routing can take place, and the client’s session is migrated from one system image to another while the client has a global transaction in progress, a migrated transaction record (MTR) is created. An MTR is deleted when the transaction finally terminates. MTRs are stored in a central file store that is provided for the Adabas System Coordinator daemons in the associated COR group.

The following information is provided.

Field Description
C

Command input field. The following options are provided:

  • D: display the selected record

    The resulting display is described below.

  • P: purge the record

    This function is provided for housekeeping by the administrator in exceptional cases. Normally, records are deleted automatically when the associated transaction completes.

    Caution:
    If you purge a record, it is possible that ATM will be unable to resolve the associated transaction with integrity.

Communication ID

The client’s 28-byte Adabas Communication ID.

TM Node The Node ID of the transaction manager that is currently local to the client who owns the transaction.

The Display function produces a display with the following format:

List Pending Error Records

To list pending error records, enter code 4. If a transaction fails in such a way that the ATM manager sets a pending response code, a pending error record might also be stored, so that the pending response code will survive a component failure, or restart of the transaction manager. Pending error records are listed like this:

The fields in this screen are as described in the section Display Pending Response Codes.

For a more detailed display of an item, type D in the C column next to the item and press Enter. The resulting display has the same layout as the Pending Response Code Details screen

To delete a pending error record, type P (for “purge”) in the C column next to the selected item and press Enter. You are prompted to confirm that the record should be deleted

Note:
If you delete a pending error record using this function, the transaction manager retains details of the pending response code in memory. If the owner of the transaction tries to do further transactional work during the current execution session of the transaction manager, the pending response code will be given. If you want to remove the pending response code from the transaction manager’s memory as well as from the recovery file, use the “delete” function of the Pending Response Details display.
