SNA Session Data Window
The Session Data Window displays the SNA session data that was retrieved from the NetView for z/OS session monitor. This
window displays the same data as if you had issued the NLDM SESS
command. It lists all SNA sessions involving the resource pair.
By default, SNA sessions are displayed in order from active
to inactive. Information is displayed on both the primary
and secondary session partners.
The title of this window consists of the following:
- The name entered in the Resource name field from the
Session Data dialog
- The NetView domain from which SNA session data was
retrieved
Sorting the Data
You can sort the information in this window in several ways with one of the following methods:
- temporarily, for your viewing purposes, by manipulating the fields
directly on the SNA Session Data Window (but note that when you close the window, these changes are not saved).
- by using the options in the
SNA Session Data Properties Notebook.
You can also use the Locate Resource function in the Session menu to open a view containing a particular resource.
Each of the columns, as described in
Available Data, has a header section which contains an up arrow and a down arrow. Clicking on the up arrow on a column sorts the fields in the table, in ascending order, by the current column. Likewise, clicking on the down arrow on a column sorts the fields in the table, in descending order, by the current column.
Temporary Sorting on the Session Data Window
You can sort and view the fields on the Session Data Window by the columns. This feature enables you to quickly view the data dynamically.
To sort the data in the columns, click on the column header:
- To display the data in ascending order, click on the header with the left mouse button.
- To display the data in descending order, click on the header with the right mouse button.
To reposition a column:
- Left click on the header of the column you want to move.
- Hold the left mouse button down while repositioning the column.
- Release the mouse button.
The column moves to the position where you released the mouse button.
Note: When you manually sort the columns on this window, the changes you make remain until you close the Session Data Window. If you close the Session Data Window and then reopen it, these changes are not saved. To save the changes you make, sort the fields using the
SNA Session Data Properties Notebook.
Filtering the Data
Clicking the plus sign on the right of the header section opens a drop down menu which contains the following options:
- Show Filter Row
- Adds the filter option to the header section above each column.
- Clear All Filters
- Removes any filters that have been set from all of the columns.
- Select All
- Selects the entire table of data.
- Deselect All
- Clears the selection of any rows or columns that were selected.
To filter the data in the Session Data Window:
- Select Show Filter Row from the drop down menu on the plus sign in the upper right corner of the header section. A <no filter> area appears beneath the heading of each column.
- Click on the <no filter> area. A field appears into which you can enter the data to appear in the table of data.
- Type the string you want to appear in the table of data and press Enter. Only the data containing the string you entered for the column appears.
Notes:
- The filter fields are case insensitive.
- No wildcards can be used in the string you enter. Wildcards are not necessary since all data entries containing the string you enter are filtered in. This means that if you enter "XYZ" the string "ABXYZC" appears in the list of data that results.
To see all the data again, select Clear All Filters from the drop down menu of the plus sign.
Available Data
The following information is displayed, in columns, on the Session Data Window:
- Primary Name
- The Primary Name field displays the name of the primary
session partner. The primary
and the secondary resource are the session endpoints
of the SNA session.
- Type (Primary)
- The Type (Primary) field displays the primary resource type.
The resource type may be any of the following:
- ILU (independent logical unit)
- LU (logical unit)
- CP (control point)
- SSCP (system services control point)
- PU (physical unit)
- Domain (Primary)
- The Domain (Primary) field displays the primary resource domain.
C-C is displayed if the resource is
casually connected. NNNA is displayed if the
resource is non-native network connected. X-NET is
displayed if the secondary resource resides in a network
different from that of the reporting session monitor.
- Secondary Name
- The Secondary Name field displays the name of the secondary
session partner. The primary
and the secondary resource are the session endpoints
of the SNA session.
- Type (Secondary)
- The Type (Secondary) field displays the secondary resource type.
The resource type may be any of the following:
- ILU (independent logical unit)
- LU (logical unit)
- CP (control point)
- SSCP (system services control point)
- PU (physical unit)
- Domain (Secondary)
- The Domain (Secondary) field displays the secondary domain.
C-C is displayed if the resource is
casually connected. NNNA is displayed if the
resource is non-native network connected. X-NET is
displayed if the primary resource resides in a network
different from that of the reporting session monitor.
- Start Date
- The Start Date field displays the date the session
was started.
- Start Time
- The Start Time field displays the time the session
was started.
- End Date
- The End Date field displays the date the session
went inactive. The following values may also
appear in this column:
- ACTIVE
- The session is still active
- BINDF
- A BIND failure occurred
- INITF
- The session failed before BIND flow.
- FORCED
- A user entered the NLDM FORCE command to copy session
data to the session monitor database.
- CONTACTED
- A PU was contacted by the SSCP, but no
Activate PU RU (ACTPU) was sent.
Therefore, no SSCP to PU session is
established.
- End Time
- The End Time field displays the time the session
became inactive. This field may be blank if the End
Date field contains a literal value.
- Sense Code
- The Sense Code field displays the sense code (in
hexadecimal) associated with session termination, if
any.
- Reason Code
- The Reason Code field displays the reason code (in
hexadecimal) associated with session termination, if
any. Reason codes are not displayed for sessions
that end for the following reasons:

- UNBIND (reason codes '00'x, '01'x, or '02'x)
- Failure before BIND flow (INIT failure) (reason code '00'x)
- Take Give (Primary)

- Indicates that the resource has been taken
over.
- GTK
- Indicates that the resource was previously given
back and has now been taken over by the

over.

traverses the CP server manager pipe used in the
Dependent LU Server/Dependent LU Requestor
(DLUS/DLUR) sessions.

- The EP Chg field indicates whether the CP (control point) has changed
since the session started. This column may be blank or may contain
one of the following values:
- PRI
- Indicates that the CP at the primary endpoint has changed
since the session started.
- SEC
- Indicates that the CP at the secondary endpoint has changed since the
session started.
- P/S
- Indicates that the CPs at both the primary and secondary endpoints have
changed since the session started.

correlation identifier (PCID) of the session. The
format of the fully-qualified PCID is (1) the network

(4) a period (.), and (5) the PCID. An example of a
