The following information is provided:
| Field | Description |
|---|---|
| Jobname | The name of the job under which this client session is running. |
| Coordinator | The transaction coordinator that has control of
the session’s transactions. Possible values are:
|
| Client Type | The internal type code for the client session,
followed by a summary interpretation. Possible values are:
|
| Terminal ID | Environment-specific identifier of the client session in character and hexadecimal format. |
| Net-Name | Environment-specific identifier of the client session. |
| Client ID | The Client ID in character and hexadecimal format. |
| Status | The session’s status code in hexadecimal followed
by a summary interpretation in character format. Possible values are:
|
| CommID | The session’s 28-byte Adabas Communication ID. |
| XID | The Transaction ID of the current transaction. This field contains binary zeros if the session has no transaction is progress. |
| Adabas Calls | The number of Adabas calls issued by the session. |
| ASA | This field contains internal information which might be useful to Software AG’s support staff in problem resolution. |
| GTQE | This field contains internal information which might be useful to Software AG’s support staff in problem resolution. |
| Last Function Call | The type of the most recent internal call sent by the TM proxy to the transaction manager for the session. Included for diagnostic purposes. |
| Transaction Model | The transaction model that is currently in use for the session. |
The remainder of the screen displays:
a list of databases with which the client is in session; and
a list of up to five pairs of pending Adabas response codes and subcodes in reverse chronological order.
If the list of databases is too long to fit on the display, "More" appears at the foot of the screen. Use PF7 to return to the top of the list and PF8 to scroll down the list.
| Field | Description |
|---|---|
| DBNo. | Database ID. |
| L/R | Indicates whether the database is local to or remote from the client; that is, whether or not the database is executing in the same operating system instance. |
| DTP | Indicates whether distributed transaction processing is enabled for the database; that is, whether it is running with the runtime parameter ADARUN DTP=RM. If this field is blank, the setting of the database's DTP parameter is not currently known. |
| ETID | If the database session has an ETID, it is shown here; otherwise the field is blank. |
| Status | A summary of the current status of the database
with respect to the current client session. Possible summary values are:
|
If the session has an open transaction under the control of the local environment’s client-side transaction coordinator (CLIENT SIDE TC), PF9 at the foot of the screen is labeled "TC". Pressing PF9 invokes the Client TC Display window showing the identifier used by the client-side transaction coordinator for the transaction.
Press PF10 to display the contents of the feedback block returned by the local ATM when the TM proxy last sent a command to it on behalf of the session.
The format of the resulting pop-up window is the same as described in section Display Error Information.
You can use the current activity function in System Coordinator administration to perform tasks against a selected session. First identify the session, and then use the PF10 "tasks" function off the session statistics display to see what tasks can be performed. One such task is the ability for administrators to automatically stop a selected session in all databases where that session is active. This is a large productivity gain because it avoids the administrator having to seek out manually those databases where this session is active.
To stop an Adabas session
Use PF10 "Tasks" off the session statistics display to see the list of tasks allowed.
Mark the "Stop Adabas UQEs" task, and press ENTER.
