This presentation will describe the capabilities provided by the enhancements for enterprise management in CICS Transaction Server 3.1.
- Real Time Analysis
- Workload Management
- Business Application Services
These are the CPSM interfaces provided.
The TSO end user interface is accessed through ISPF. Users can manage all of the CICS regions and resources in the CICSplex from this single view. Because the size of the screen is limited, many scrolling activities may be necessary if there number of items to be displayed is large.
The Web User Interface is a browser based interface, more data is displayed in the window and provides an easier and intuitive navigation. With the definitional capabilities added in CICS TS V2.3, most of the CPSM activities can be accessed through the WUI.
The TSO interface is planned to be removed in the next release.
This shows the enhancements to CPSM in V3.1. Most of the enhancements are in the Web user interface, it will have more functionality and better usability. It will enable users to replace the current TSO end user interface.
The batch job is submitted through the BATCHREP view in the TSO user interface, and a batch like transaction will run in the CMAS to access the CPSM data repository. Information about the job status was held in an internal table that was not accessible to CPSM APIs, so the Web user interface did not have an interface for BATCHREP.
CPSM in CICS TS V3.1 will externalize the BATCHREP resource table. This will enable access from CPSM APIs. Actions CHECK and EXECUTE are added. CHECK will perform a syntax check to the supplied input commands. EXECUTE submits the BATCHREP processing. There will also be a new field PROCESS added in the resource table to indicate the status of the job.
This table will enable WUI to access the batched repository update facility. A new view is supplied in WUI to run the BATCHREP job.
In addition to the access from WUI, there will also be a new a batch utility program supplied that can be submitted through JCL. This will enable CPSM definitions to be maintained from a job step, without using the user interfaces. The program name is EYU9XDBC. It will issue a series of CPSM APIs to run the BATCHREP processing.
This is a screen shot of the WUI view for BATCHREP.
The view will show BATCHREP tasks that are currently running. The EXECUTE and CHECK buttons on the bottom will allow users to input the necessary parameters.
//BATCHREP EXEC PGM=EYU9XDBC,REGION=0M
//STEPLIB DD DISP=SHR,DSN=CICSTS31.CPSM.SEYULOAD
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
CICSPlex/SM Batched Repository Update Utility Version 310
EYUXD0908I A batched repository update has been submitted to run in CMAS IYK4Z0E1.
EYUXD0909I CICSPlex SM Batched Repository Update Utility is terminating.
This is an example of the batch utility program.
The input parameters will be supplied in the SYSIN DD statement. The output of the utility program will be written to SYSOUT and the messages will indicate whether the job was successfully submitted.
These are the functional enhancements in the Web user interface that will be provided in CPSM in CICS TS 3.1. They are targeted to make the WUI more functionally equivalent to the TSO end user interface.
Dynamic selection list enable easier definitional capabilities. When creating a definition for CPSM, if a certain field is left blank, a screen will be displayed showing the list of valid values for that field. This function will now be provided in the WUI.
There will be an icon to the right of the text input box indicating that the field is enabled for dynamic selection list. When the icon is clicked a view will be shown with the valid values for that field. There is also a filtering capability for the list.
The TSO interface provides the ability to specify filters prior to showing the view. From the command line, users can specify which view they want to display and additionally specify a filter. If the filter is specified, only the matching resources will be shown on first display. Users will have the opportunity to enter filter values regardless of the size of result set that will be returned .
In previous releases of the WUI, filtering could be done only after opening the first view.
In CICS TS 3.1 users have the ability to specify filters before displaying the first view. If the view is enabled for filter confirmation, a filter confirmation screen will be shown before displaying the tabular view. The filter confirmation can be enabled through the WUI view editor. The IBM supplied view will not have filter confirmation as default.
This is a sample flow of setting the filter confirmation.
It is enabled through the View editor.
The WUI can now be tailored to issue warnings before it opens a view that will generate large numbers of records. Following a warning users will have the opportunity to alter the filter values on the view in order to reduce the number of results returned. This improves WUI performance by reducing unnecessary waits.
The threshold for the warning can be set in a user group profile. If the user does not have an associated user group, or if security is inactive in the WUI server, the DEFAULTWARNCNT parameter in the WUI startup parameter will be used. The default is 0, meaning that the warning count is not enabled.
- create a user group with the same name in the security manager
- associate the user to a user group in the security manager
- activate security in the WUI server.
The administrators will use the User Editor to create/edit/delete user groups. This is a sample view of the User Editor to create a user group profile.
Add to favorites
In CICS TS 3.1, all WUI users now have the ability to save tabular and detail views on an ad-hoc basis to an easily-accessible and editable menu of favorites. This allows users to reach frequently used views with just one click. Administrators have the additional authority to update the favorites .
There will be an icon on tabular and detail views that will enable users to add the view to their favorites list. The link to the view will be added on the navigation frame under “favorites”.
There is a new Favorites Editor, which will enable users to maintain their favorites list.
To add a favorite, simply click on the icon on top of the view and enter the name of the link.
The link will be shown on the navigation frame.
The Favorites editor can be used to maintain the favorites list.
This is an example of using the favorites editor, changing the context and scope settings.
Administrators can also manage the user’s favorites list through the User editor. This example shows an example of editing a users favorite.
The Web user interface has some improvements in its usability and presentation. The improvements are focused on reducing white space area, maximize the use of screen space in WUI views and menus.
CICS TS V2.3
CICS TS V3.1
The “Select all” and “Deselect all” button has been changed to an icon, thus reducing the some white space on tabular views.
For Internet Explorer, an alt text will appear when the pointer is above the icon.
In previous releases, a detail view of a resource was displayed in one column. Because all the attributes were positioned on the left side of the view, it left a large amount of white space in the right side of the view.
The use of screen space on detail views has been improved by providing the ability to display the information in two columns rather than one. Users can design their own two-column detail views using the View editor.
IBM supplied views will remain single columned.
This shows an example of creating a two-column detail view using the View editor. Selecting the view type as “Two column detail form” will enable attributes to be positioned in two column.
The filters on the views are now collapse-able. If the filters are not needed users can collapse the filters to provide more screen space for data. Collapsed filters can be expanded whenever necessary. The ‘+’ or ‘-’ icon on the left can be used to expand or collapse the filters.
The new WUI startup parameter FILTERSTYLE specifies the state of the filters to be shown when the view is accessed.
color intensity changes to
- column headers
- piano lining
CICS TS V2.3
CICS TS V3.1
Other improvements are for the usage of colors and intensity. The lighter color and intensity for the filter area, column headers and piano lining makes it easier to see the data being displayed.
There has been some simplification of BAS (Business Application Service) views in the WUI .
BAS provides two models to maintain CICS resource definitions. One is the standard model, which is much like the CEDA model in CICS, and the other is the advanced model, which a single resource can be deployed with different attributes, to different CICS systems.
The navigation for BAS in WUI has been changed to supply submenus for each of the models.
This shows the BAS administration view and its submenus for the two models.
There is a new view in WUI to manage BAS resources.
Previously, the WUI displayed list of resources in a resource group by types, using xxxINGRP views (ex. TRNINGRP, FILINGRP, TRMINGRP, etc.)
There is a new table added in CPSM called RESINGRP which can be accessed via CPSM API. By accessing this table the WUI will provide a new RESINGRP view that will show all the resources associated in a resource group.
CPSM will have support for all the new functions provided in CICS TS V3.1.
This shows the changes made to the CPSM resource tables.
CPSM WUI has been improved in several ways in order to provide a user experience that is equivalent to that of the TSO end user interface. These enhancements are aimed at making the Web User Interface more powerful and more usable, and eventually functionally equivalent to the TSO EUI.
There are improvements with the visual presentation of the WUI, along with some usability enhancements for working with BAS through the WUI.
CPSM will have support for all the new functions provided in CICS TS V3.1.
