z/OS IP Session Data Window
The z/OS IP Session Data Results window displays the IP session data
for a resource. This window displays the results from the session status
search that was submitted on the z/OS IP Session Data dialog.
The title of this window consists of the following:
- The name entered in the hostname or IP address from the
previous panel
- The NetView domain from which z/OS IP session data was
retrieved
Sorting the Data
You can sort the information in this window in several ways
using the options in the 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.
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 z/OS IP 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:
- Service Point
- The Service Point field displays the name of the TCP/IP stack.
- Active Sessions
- The Active Sessions field displays the number of active sessions found for the TCP/IP stack.
- SP System
- The SP System field displays the type of system for the TCP/IP stack.
- SP Host Name
- The SP Host Name field displays the fully qualified host name for the TCP/IP stack.
- SP IP Address
- The SP IP Address field displays the fully qualified TCP/IP address for the TCP/IP stack.
- SP IPSTAT
- The SP IPSTAT field displays the IPSTAT value used by the SP. This is
either the value specified for the IPSTAT keyword on the SP's TCP390 AON
control file entry or the default value specified in the FKXIPSTAT common
global variable. Note: Behaviour is unpredictable for SP IPSTAT values other
than "DETAIL" or "SUMMARY", for example if an operator were to accidentally
set the FKXIPSTAT common global variable to some other value.
The default SP IPSTAT value of "DETAIL" indicates the IP session data was
retrieved using SNMP. SNMP data retrieval is slower than NETSTAT data
retrieval, however it returns data for more fields than NETSTAT does. For
example, the Connection ID field displays the connection id value when
SNMP data retrieval is used. For large numbers of IP sessions, for
example 2,000 or more, IP session data retrieval using SNMP may be very
slow and may require several minutes.
An SP IPSTAT value of "SUMMARY" indicates the IP session data was
retrieved using NETSTAT. NETSTAT data retrieval is faster than SNMP data
retrieval, however it does not return data for as many fields as SNMP
does. For example, the Connection ID field is blank when NETSTAT data
retrieval is used.
An SP IPSTAT value of "MIGRATE" indicates that NetView for z/OS does not
have Apar OA06743 applied. IP session data retrieval will be done using an
older SNMP method that may be extremely slow for large numbers of sessions.
Installing Apar OA06743 is recommended.
- NetView Domain
- The NetView Domain field displays the domain of the NetView.
- MVS Procedure
- The MVS Procedure field displays the MVS procedure that was used to start TCP/IP.
- Client Port
- The Client Port field displays the client port number for an active IP
session.
- Client Address
- The Client Address field displays the TCP/IP address of the active session.
- Send
- The Send field displays the number of bytes sent per session.
This field is blank when SP IPSTAT has a value of "SUMMARY".
- Rec
- The Rec field displays the number of bytes received per session.
This field is blank when SP IPSTAT has a value of "SUMMARY".
- Connection ID
- The Connection ID field displays the TCP/IP connection ID for the session.
This field is blank when SP IPSTAT has a value of "SUMMARY".
- Logical Unit (SLU)
- The Logical Unit (SLU) field displays the LU associated with the
client workstation. This field is blank when SP IPSTAT has a value of "SUMMARY".
- Appl (PLU)
- The Appl (PLU) field displays the MVS application that the client is
in session with. This field is blank when SP IPSTAT has a value of "SUMMARY".
- Local Address
- The Local Address field displays the local TCP/IP address.
This field is blank when SP IPSTAT has a value of "DETAIL".
- MVS Socket
- The MVS Socket field displays the TCP/IP port assigned for the session type.
- Status
- The Status field displays the status of the connection.
This field is blank when SP IPSTAT has a value of "DETAIL".
