Issue/Introduction
The Configure Datacom/AD for Use with CA 7 documentation has a good amount of detail, but I still have various questions about these sets of jobs (AL2DCA10-70) and other questions that are not explained all that well
(Q1) Can I use my current Datacom/AD MUF and share CA 7 with the other products (CA 11, ENF, JOBTRAC, etc.) or should I create a new MUF for CA 7. Follow up would be that CA 7 requires changes to some startup options. Will this affect my other products?
(Q2) Do I need to setup up External Security from the start?
(Q3) Does the Datacom/AD MUF need to be up in order to run these sets of jobs (AL2DCA10-70)?
(Q4) Does the CA 7 task need to be up or down when submitting these sets of jobs?
(Q5) Can these jobs be run before the conversion or upgrade?
(Q6) Any other special considerations?

Resolution
(A1):
This can be seen in the Datacom/AD Guidelines. It states that "[CA] WA CA 7 Edition can use a Datacom/AD MUF with similar Broadcom products like CA 11. We do not recommend running [CA] WA CA 7 Edition in the same MUF as CAIENF .
(A2):
Although it is recommended to set up External Security, this should be done after the MUF configuration and CA 7 conversion process as there is a chance a Security Administrator can set up wrong security rules in place, which can cause the MUF to not come up initially. The MUF log will issue a warning message that indicates that the tables are not protected by external security. CA 7 has its own internal security which provides most of the same functionality as external security. External security controls all resources from a SINGLE point of administration, whether you are using RACF, TOP SECRET or ACF2. All CA 7 resources are defined to and controlled by the security package. Internal security controls the same resources, but the resources are controlled by CA 7. It depends on which source you use to perform the control, either through security admin or product admin
CA 7 has jobs that you can run to set up rules for ACF2, RACF, and Top Secret. You can see the commands for each product in your CA 7 CAL2OPTN PDS for each specific security package. Please follow Article 92861 for more information
(A3):
For these jobs, the flower box instructions state that the Datacom/AD MUF needs to be up and running.
(A4):
Since these jobs have no effect on the current CA 7 task running, It does not matter if CA 7 is up or down.
(A5):
As mentioned before, these jobs are for the sole creation of database 770 used for CA 7. These jobs can be run prior to the conversion/upgrade.
(A6):
[SC1] - LOGGING: One consideration would be since CA 7 does a good amount of logging, set your log (LXX) size appropriate to your site standards. Also, follow Article 26465 setup automation to capture informational message DB00308I to start spilling blocks from the log the recovery file (RXX). Automation would submit CA 7 job AL2DBSPL to start the spill. This is explained in Article 21516.
[SC2] - XCF: Another consideration would be to follow the best practice and run CA 7 on the same LPAR as the MUF for performance reasons. This cannot always happen so be sure to set up follow Article 38170 on how to set up XCF if CA 7 will be on a different LPAR than where the MUF is executing.
[SC3] - SHADOW: If for some reason the Datacom/AD MUF were to abend/fail, CA 7 would stop, and scheduling operations would be impacted. To make sure this would not happen, we recommend setting up the MUF with shadow technology. This will create another MUF instance on "standby" mode and takeover when the primary MUF shuts down or abends. Follow Article 25223 on how to set up and implement shadow on a MUF
