Scaling Up or Scaling Out Middleware Deployment Procedure

The process of increasing a cluster's capacity by adding additional server instances to the cluster on an existing machine, or adding machines to the cluster to host the new server instance, is called Scaling up. Scaling Up and Scaling Out Managed Server can be achieved through the command line using EM CLI commands available in Enterprise Manager 13c.

In this use case, the Instance GUID of the SCALEUP procedure is retrieved, which in turn is used to retrieve the input properties file of this instance of the procedure. After making necessary updates to the properties file, like adding another user-friendly so on, the procedure is submitted with the updated properties file as the input:

Here is the step-by-step process:

  1. To retrieve the GUID of the Deployment Procedure, run the following command:
    ./emcli get_procedures | grep SCALEUP_       

The output appears in the following format:
<proc_guid>, <procedure_type>, <Procedure_name>, <Dsplay name>, <version>, <Parent procedure name>

For example:
./emcli get_procedure | grep SCALEUP
B35E10B1F154B4EEE040578CD78179DC, FMW Provisioning, SCALEUP DP, Scale up/Scale out Middleware, 2.0, ORACLE
  2. Use the Instance GUID retrieved in the previous step to get input properties of an instance of the procedure:
    ./emcli get_instance_data -instance=<instance_guid> -exec=<execution_guid>

For example:

emcli get_instance_data -instance=B35E10B1F140B4EEE040578CD78179DC > instanceData.properties
A properties file with the name instanceData.properties is created.

    Note:

    This step is valid only if the instances of the procedure is available, which means that the procedure should have been submitted at least once in the past. If you have never submitted the procedure, then you may see an error message as follows:

    Instance with GUID=<guid> is not found in repository. Please make sure the value is correct and try again.

  3. Use an editor to open the generated properties file instanceData.properties, and update the existing values in the properties file.

    For example, here is a sample properties file used with the values updated. For information about these parameters, see Table A-6.
