Change Information Source

This option can be used to route monitoring requests to any active coordinator daemon (see screen below).

To access the Change Information Source screen from the Session Monitoring menu

Select service 0 or enter the command 0.1 on a command line.

This screen shows the users that are active in a job managed by the Adabas System Coordinator. The following information is provided:

Field	Description
User ID	The User ID (last 8 characters only). IDs comprised of special characters are normally generated by the system.
Txn	The current or last Transaction ID executed (TP systems only). The value ‘*timeout’ indicates that the inactivity threshold has been reached for this client session.
Dormant	The amount of time since the last user activity.
Memory	The amount of memory allocated by the user.
Adabas Cmds	The number of Adabas commands executed for this user.
Quick Locate	The number of times the coordinator optimized command processing because two or more commands for the same user were executed consecutively.
Type	Indicates whether or not the user is managed by an Adabas System Coordinator daemon. A value of ‘S’ indicates that the user is managed by a Adabas System Coordinator daemon.

PF keys can be used to sort the user list in various sequences:

Key	Description
PF5 (SortN)	The list is sorted by User ID.
PF9 (SortT)	The list is sorted in descending time since the user was last active.
PF10 (SortU)	The list is sorted in descending order of the number of Adabas calls issued.
PF11 (SortO)	The list is sorted in descending order of user search optimization. This shows the number of times for each user that an index search was avoided.
