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.
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.
This option provides access to current statistics maintained by the transaction manager, and allows the administrator to reset statistical counts to zero.
Selecting option 1, Statistics, from the Transaction Manager Information menu displays the following menu:

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: |
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:

The following information is provided on the left of the screen:
| Function | Description |
|---|---|
| CommID | The Adabas communication ID of the client session for which the pending response code is set. |
| ID | The last 8 bytes of the Adabas communication ID of the session for which the pending response code is set, in character format. |
| Jobname | The name of the job under which the client session is or was executing. |
| Response code | The pending response code. |
| Sub-code | The pending response code’s subcode. |
| Time | The time at which the pending response code was set. The date has the format MM/DD. |
| ISN | The ISN of the record which represents this pending response code in the manager’s PRR file. |
The right-hand side of the screen displays a list of the databases that were changed by the transaction which caused the pending response code to be set.
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.
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.
Selecting option 4, Display Known Databases, from the Transaction Manager Information menu will display a list of all databases in the network that are known to this ATM. The list includes all databases that are enabled for two-phase commit processing; that is,
all local databases that are running with ADARUN
DTP=RM, and
all remote databases that are running with ADARUN
LOCAL=NO and have been identified to the transaction manager by
remote ATMs.
Other databases may appear in the list, depending on the way they are used. The display has the following format:

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.
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.

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.
