Before you begin
You must have access to the couple data set format utility, IXCL1DSU,
in SYS1.MIGLIB. If you plan to modify the automatic restart management policy,
you must have access to the administrative data utility, IXCMIAPU, also in
SYS1.MIGLIB, and have UPDATE authorization to the RACF FACILITY class MVSADMIN.XCF.ARM.
To start a policy, you must have READ authorization to the RACF FACILITY class
MVSADMIN.XCF.ARM.
About this task
Though servers automatically register with automatic restart management,
you must activate the arm component itself, which means you must:
- Allocate an ARM couple data set.
- Start the automatic restart management policy.
If automatic restart management is not active, WebSphere Application
Server for z/OS issues an error message to the hardcopy log.
You are
not required to change the automatic restart management policy. However, you
will have to modify this policy if you want to create custom restart groups.
For instance, it is not required or recommended that you start the node agent
or deployment manager servers on another system. These servers will never
have any transactional recovery to perform. Therefore, they should only be
set up for restart-in-place. For complete information about how to modify
the policies, see z/OS MVS Setting Up a Sysplex (SA22-7625).
The
following procedure is intended to give you enough information to get automatic
restart management running. Defining automatic restart management policies
would require the z/OS manual mentioned above.
Procedure
- If you have not already formatted a couple data set for policies,
do so now. For details, see z/OS MVS Setting Up a Sysplex
- Submit the job to format the ARM couple data set.
- Optional: Modify the automatic restart management policy.
To get started, you do not need to modify the policy. If you do want
to modify the automatic restart management policy, go to z/OS MVS Setting
Up a Sysplex, and follow the instructions in that manual.
- Issue the following operator commands to start the automatic restart
management policy:
SETXCF COUPLE,TYPE=ARM,PCOUPLE=(dsname,vvvvvv)
SETXCF START,POLICY,TYPE=ARM
where
- dsname
- Is the data set name for the couple data set.
- vvvvvv
- Is the volume serial of the volume on which the couple data set resides.
Results
You are done when the SETXCF commands complete successfully.
