CAISDI Requirements

CAISDI consists of the following components: soap, med, and els. In the past, these components were installed separately. Now, they are installed as one product.

CAISDI has the following installation requirements:

• An IBM supported z/OS version.
• Use a region size of 4 MB or larger.
• CAISDI/med uses approximately 24 KB of the extended common service area (ECSA) for loading common storage resident services and intercepts.

  Certain types of service calls use approximately 100 KB of ECSA while the service call is outstanding; however, CAISDI makes extensive use of cross-memory services to avoid the need for common storage areas.

• CAISDI/els uses varying amounts of CSA depending on which products use this component.

  The CAISDI/els Interface Controller reports the ECSA usage for each product separately.

• CAI.CAW0OPTN contains the CAISDI initialization statements for all CAISDI components. If the parameter data set is to be shared by multiple z/OS systems, it must reside on a shared DASD volume.
• CAI.CAIEVENT contains the event definitions for the CAISDI/els component. The event members are provided by the CA Technologies products that use this interface.
• CAISDI provides the interface to CA Service Desk over a network connection using TCP/IP. Be sure TCP/IP is up and running on at least one z/OS system. The CAISDI/soap client will be installed there.
• The userid associated with running the CAISDI/soap Client address space must have the UNIX System Services profile defined to UID 0 or be a SUPERUSER (BPX.SUPERUSER).
• Verify that CA Service Desk is installed and properly configured.
• Some products generate Service Desk Request Description content in HTML format.

By default, CA Service Desk renders embedded HTML directives in the request description field. This capability can be deactivated. To render the request text properly, your CA Service Desk server must support HTML rendering. Contact your CA Service Desk administrator and ask that this task be performed.

This task involves customizing the detail_cr.htmpl form to add keeptags and keeplinks support.

Note: For more information about the installation and configuration of CA Service Desk, see the CA Service Desk Installation Guide.

The following lists the minimum storage requirements for each CAISDI distribution library and does not necessarily represent the actual distribution library allocation that is provided during the installation. Data set allocation JCL and (MSM) XML contains a block size of 0 for FB data sets with a LRECL of 80. This change was made in order to follow both IBM’s SMP/E packaging standards, and CA’s packaging standards. Specifying BLKSIZE=0 will allow your system to choose the most efficient block size for these data sets.
