Editing the classification rules for a service class
The classification rules for a service class identify the CICS
transactions associated with a particular service class. To add classification
rules to a new service class, complete these steps:
- Within the Service Classes window, select the service class whose
classification rules you want to define, and click Edit
Rule.
The Rule Editor window is displayed.
Figure 8. The Rule Editor window for assigning a new service class's classification rules
- Right-click the Rule entry in the left pane,
and select one of the following transaction-selection criteria from
the menu:
- TranID
- Transactions in this service class are based on their transaction
names.
- LUname
- Transactions in this service class are based on the VTAM® terminal that invoked them.
- UserID
- Transactions in this service class are based on the user ID
associated with them.
- CICSname
- Transactions in this service class are based on the CICS® region that is running them.
The CICSname refers to the APPLID of the region, not the JOBNAME.
Figure 9. The Rule action menu
- Within the input window, enter an initial CICS transaction, VTAM
terminal ID (LU name value), user ID, or CICS region name you want
to assign to this service class rule. You enter only one value in
this field; additional criteria can be added later:
Figure 10. The input window where you define the test strings for a criterion
These are the valid characters for the test string, A-Z,
a-z, 0-9, and any of the following characters, $ @ # . / - _ % & ¢
? ! : | = ¬ ; < >. Note, the comma (,) and double-quote (")
characters are not valid.
When you are finished specifying the
value to assign to this criterion, click OK.
- To add an additional criterion to your rule, right-click the Rule entry or the existing selection criterion you
want to apply it to, and select the new criterion type.
- If you right-click Rule, the new criterion
is added to the existing criterion as an OR condition.
It is appended to the Rule Editor's tree view at the same level as
the existing criteria.
- If you right-click an existing criterion, the new criterion is
appended to the existing criterion as an AND condition.
It is added to the Rule Editor's tree view subsidiary to the criterion
you selected.
- When you have finished defining the rules for this service class,
click Save.
Note:
A service class is not completely defined until you
assign its classification rules. The Save button
remains grayed out until you complete this step.
To edit a service class's existing classification rules, complete
these steps:
- Within the Service Classes window, select the service class whose
classification rules you want to update, and click Edit
Rule.
The Rule Editor window is displayed and shows the service
class's existing classification rules.
Figure 12. The Rule Editor window for editing a service class's existing classification rules
- In this window, you can add a new criterion, update the test strings
assigned to an existing criterion, or delete a criterion.
- To add a new criterion to the existing rule, right-click the Rule entry or the existing selection criterion you
want to apply it to, and select the new criterion type. Within the
new value window, list the CICS transactions, VTAM terminal IDs (LU name value),
user IDs, or CICS region APPLIDs
you want this criterion tested against. Specify the test strings as
previously noted.
Figure 13. The new value window
As before, if you add the new criterion at the same level
as other criteria, it is an OR condition, whereas if you add it at
the subsidiary level, it is an AND condition.
- To edit an existing criterion, select it in the left pane of the
Edit Rule window. Using the right pane, you can either append a new
test string to those already present, edit an existing test string,
or delete an existing test string:
- To add a new test string, click Add in the
right pane.
The new value window is displayed. Enter one or more
additional test strings, including the wildcard character "*" if needed
and separated by commas and click OK.
- To edit one of the criterion's existing test strings, select it
in the right pane, and click Edit.
The edit
window is displayed. Edit the test string as appropriate. You can
also append additional test strings by inserting a comma at the end
of the current string and then keying it in.

Click OK.
- To delete one of the criterion's test strings, select it in the
right pane, and click Delete.
- To delete a criterion, right-click it, and select Delete (see Figure 11). Deleting a criterion also deletes all criteria
subsidiary to it (in other words, those appended to it as AND conditions).
- When you have finished updating the rule for this service class,
click Save in the Rule Editor window.
After you have defined the appropriate classification rules for
your service classes, your next step is usually to define one or more
service policies for your CICS environment
and to activate one of them; see Adding or editing a service policy and activating a service
policy.
