Install PowerCenter 10.5 on Kubernetes with Informatica Deployment Manager

Update a Service

Update a Service

You can update the node image, worker node count, and pod resources of an application service in a domain. You can also set additional environment variables and expose additional ports for the service.
  1. On the Informatica Deployment Manager home page, select
    Manage Domain
    .
    The
    Manage domain
    window appears.
  2. On the
    Service
    panel, click
    Update service
    .
    The
    Update service
    page appears.
  3. Optionally, you can choose to configure Secure Shell (SSH) protocol for secure authentication to update the service on a remote host. If you do not want to set the secure authentication, go to step 5.
  4. If you enable secure authentication, set the authentication type to
    Password
    or
    Key
    .
    • For password type authentication, enter the machine IP address or host name, user name, password, and port to connect to the host machine.
      By default, the SSH connection uses port 22.
    • For key type authentication, enter the machine IP address or host name, user name, path of the host authentication key, and port number.
  5. In the
    Update Service
    section, enter the names of the domain and the service to update.
  6. Enter the working directory of the service.
  7. On the drop-down, select the application service to update.
  8. Specify the number of worker nodes and the name of Docker image deployed on the nodes.
    You can update the worker node count only for the Data Integration Service and PowerCenter Integration Service.
  9. Optionally, set additional environment variables and expose additional ports for the service. If you choose to update the PowerCenter Repository Service and if the service is running on a Microsoft SQL Server database, you must set the variable ODBCINI to
    /home/Informatica/K8sVolume/pcrs/odbc.ini
    even if you do not set any other additional environment variable for the service.
    If you choose to set additional environment variables, expose additional ports, or add additional host alias names for the service, ensure that you also include the existing values in the list. This prevents the existing domain configurations from getting affected.
  10. Optonally, if you choose to update the Data Integration Service or PowerCenter Integration Service, you can enable Kubernetes autoscaling.
    The Horizontal Pod Autoscaler scales the number of pods in a deployment or replica set based on the CPU utilization mentioned for the CPU load factor. Kubernetes creates horizontally scalable worker nodes that are added to the grid with the Data Integration Service process enabled.
  11. If you choose to enable Kubernetes autoscaling, enter the worker node, CPU utilization, and memory utilization information to autoscale:
    • Minimum number of nodes
      . The minimum number of worker nodes to create in the domain. Default is 2.
    • Maximum number of nodes
      . The maximum number of worker nodes to create in the domain. Default is 4.
    • CPU load factor
      . Kubernetes autoscales the Informatica worker nodes after monitoring the Kubernetes worker node and when the Kubernetes worker node reaches the value set for the CPU percentage metrics. Default is 75 percent.
    • Memory load factor
      . Kubernetes autoscales the Informatica worker nodes after monitoring the Kubernetes worker node and when the Kubernetes worker node reaches the value set for the memory percentage metrics. Default is 80 percent.
  12. Optionally, choose to configure the pod resources, and then update the request and maximum limit values of CPU and memory resources allocated for the service.
  13. Click
    Update service
    .
The service is updated. You can view the status of the service along with the tasks performed by the installer in the log summary.
