Activating automatic restart management (ARM)

Follow this procedure to activate automatic restart management (ARM).

Before you begin

You must have access to the couple dataset 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:
  1. Allocate an ARM couple dataset.
  2. 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

  1. If you have not already formatted a couple dataset for policies, do so now. For details, see z/OS MVS Setting Up a Sysplex
  2. Submit the job to format the ARM couple dataset.
  3. 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.
  4. 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 dataset name for the couple dataset.
    vvvvvv
    Is the volume serial of the volume on which the couple dataset resides.

Results

You are done when the SETXCF commands complete successfully.
