Configure the TCP/IP Stack Cloud Data Sets

page 5 of 14

A panel to configure the stack's cloud data sets is displayed. These data sets are required. The Include data set is used to persist provisioned network resources in the TCP/IP stack over stack restarts and system IPLs. The Dynamic update data set is used to dynamically define provisioned network resources to the TCP/IP stack.

Choose a data set allocation method for the include data set.
- Click Specify a pre-allocated data set if you have allocated a data set for this purpose.
  Enter the name of an allocated PDSE data set and member that exists on shared Direct Access Storage Device (DASD) to be used as the stack cloud include data set. Use of Partitioned Data Set Extended (PDSE) members is required. PDSE members will be created dynamically from the previously allocated PDSE library. The data set must exist on shared DASD when the TCP/IP stack exists on a system that is remote from the system running z/OSMF.
- Click Use a workflow to allocate a data set of a customizable size… to use a workflow to allocate a PDSE of a customizable size.
  1. Click Allocate data set using workflow. A workflow named “ezb_cloud_allocate_stack_pdse” is created.
  2. Open the z/OSMF Workflows tab.
  3. Select the workflow and choose Actions > Open.
  4. Select the first step and choose Actions > Perform.
  5. Customize the workflow with a unique data set name and a customized size. The data set must be a PDSE that exists on a shared DASD volume.
  6. After the workflow completes, enter the name of the data set with a PDSE member name, for example, ‘SYS1.CLOUD(V007INCL)’. The member that you specify will be created dynamically within the PDSE.
  Authorization requirements for creating a workflow
  The user’s z/OS user ID must have the following access:
  - READ access to the <SAF-PREFIX>.ZOSMF.WORKFLOW.WORKFLOWS profile in the ZMFAPLA class.
  - READ access to the <SAF_PREFIX>.*.izuUsers profile in the EJBROLE class, or at a minimum, READ access to the <SAF_PREFIX>.IzuManagementFacilityWorkflow.izuUsers resource name in the EJBROLE class.
  - READ access to the <SAF-prefix>.ZOSMF.SETTINGS.SYSTEMS.VIEW profile in the ZMFAPLA class.
- Click Dynamically allocate data set to have the specified data set dynamically allocated by using your installation’s default size.
  Enter the name of a data set to be dynamically allocated and specify a member name. If you have had a data set dynamically allocated by using this method for this or another TCP/IP stack, you can specify that data set name and a unique member.
  
  Dynamically allocated data sets are dynamically deallocated when no longer referenced by any Cloud TCP/IP stacks.
Choose a data set allocation method for the dynamic update data set. Follow the instructions above for the include data. You might choose the same or different data sets for the include data set and the dynamic update data set. If you choose to use the same data set as the include data set, you must also choose the same data set allocation method radio button as you did for the include data set and specify a unique member name. Similarly, you might specify the same data set that was specified for other TCP/IP stacks when the same data set allocation method is specified.
Click OK. A message is displayed, which discusses the expected behavior if the TCP/IP Profile technology of Network Configuration Assistant is used for this TCP/IP stack.
Click OK to close the message window and return to the Cloud perspective.

If you are not using the TCP/IP Profile technology to manage your TCP/IP Profile, edit the TCP/IP Profile data set on your system for the TCP/IP stack name that you entered. Add an Include statement that references the Include data set name that you entered. For example, if you entered an Include data set name of 'USER1.TCPIP.INCLUDE(TCPIP)', add the following Include statement to the+TCP/IP Profile data set: INCLUDE USER1.TCPIP.INCLUDE(TCPIP)
