Get list of sessions

Note: Many $functions have been deprecated in favor of Object Oriented methods. But there is no OO equivalent for the $Session_List function.

$Session_List returns information about sessions to a $list, accepts three arguments and returns a the number of items added to the output $list. All errors result in request cancellation.


%rc = $Session_List(listid, [sesid], [owner])

%rc A numeric variable that is set to the number of added items.
listid The identifier of the $list to receive the output from $Session_List. This is a required argument.
sesid The identifier of the session for which information is to be returned. This argument can contain wildcards — for example PEQ* indicates that information is to be returned for all sessions beginning with the letters "PEQ".

This is an optional argument and defaults to asterisk (*), which means all session IDs are to be listed.

owner The userid that owns the session for which information is to be returned. This argument can contain wildcards, though for a non-system manager user, only sessions owned by the requesting user and public sessions will be listed. Note that an asterisk (*) value will list all private and public sessions, but a double-quote asterisk ("*) will list public sessions only.

This is an optional argument and defaults to the userid of the invoking user.

Output format

The format of the data in the output $list is:

Col 1-10 Owner of the session; * for public sessions.
Col 11-16 Session timeout value.
Col 17-30 Session creation time in YYYYMMDDHHMISS format.
Col 31-44 Last session access time in YYYYMMDDHHMISS format. If the session is currently open this value is the time of the $Session_List invocation and will have the same value for all sessions open at the time of the $Session_List call.
Col 45-50 User number with session open. If the session is not currently open by any users these columns contain all blanks.
Col 51- The session ID.

Usage notes

  • The session ID and owner specified in the second and third arguments can be explicit names or can contain the following wildcard characters:
    * Matches any number of characters including none
    ? Matches any single character
    " Indicates that the next character must be treated literally even if it is a wildcard character.

    For example:

    • C*D matches "CUSTID", "COD", or "CLOD".
    • S??T matches "SALT", "SLOT", or "SORT".
    • "* matches "*" (that is, public sessions, in the case of the owner).


The following example displays information about all sessions owned by the current user:

%list = $ListNew %rc = $Session_List(%list) %rc = $List_Print(%list)
