Upgrade Procedure

The following procedures explain how to upgrade the monitoring solution.

Stop the ABAP Agent Services

Before the upgrade, stop all the services:

  1. Deactivate the instrumentation in transaction /DVD/APPD_CUST.

  2. Stop all performance metric collectors in transaction /DVD/APPD_DI_CON.

  3. Stop the HTTP SDK instances in transaction /DVD/APPD_STATUS.

  4. When a separate Linux machine is used for HTTP SDK instances, stop the SDK manager.

 

Shared SDK manager

 A single Linux machine and SDK manager instance can be shared by multiple SAP systems. Make sure to apply steps 1 - 3  and all following update steps for all SAP systems that use the same SDK manager instance.

 

Update the ABAP Agent

Import all transport requests in the following order:

  1. Datavard Reuse Library
  2. Datavard Insights
  3. AppDynamics ABAP agent

Update the HTTP SDK

  1. If HTTP SDK instances are running directly on SAP application servers:
    1. Update ABAP agent.
    2. Use the AppDynamics HTTP SDK Installation Manager to update HTTP SDK, see Installing HTTP SDK Automatically.
  2. If HTTP SDK instances and SDK manager are running on a separate Linux machine:
    1. Unzip the contents of the downloaded file.
    2. Update the HTTP SDK manually, see Installing HTTP SDK Manually.

Start all ABAP Agent Services

  1. When a separate Linux machine is used for HTTP SDK instances, start the SDK manager.
  2. Start the HTTP SDK instances in transaction /DVD/APPD_STATUS.
  3. Activate the instrumentation in transaction /DVD/APPD_CUST.
  4. Start all performance metric collectors in transaction /DVD/APPD_DI_CON.

Uninstall Procedure

The following procedures explain how to uninstall the monitoring solution.

Stop the ABAP Agent Services

Before the uninstallation, stop all the services:

  1. Deactivate the instrumentation in transaction /DVD/APPD_CUST.
  2. Stop all performance metric collectors in transaction /DVD/APPD_DI_CON.
  3. Stop the HTTP SDK proxies in transaction /DVD/APPD_STATUS.

Uninstall the ABAP Agent and Datavard Insights

To uninstall, import these deletion transport requests in to the SAP system, in the following order:

  1. Uninstall transport for ABAP Agent
  2. Uninstall transport for Insights with Reuse library

A deletion transport request is a regular SAP transport request (workbench request) that contains a list of repository objects flagged for deletion. When importing these transport requests, the objects from the list are removed from the system, including data in the database tables. These transport requests are created based on original installation requests (same list of objects) and when you uninstall they have to be imported in reverse order as installation transports.

Uninstall the HTTP SDK

When a separate Linux machine was used for HTTP SDK instances, make sure no more SAP systems are using this system and stop the SDK manager.

To uninstall the HTTP SDK, delete the following folder:

  • <appdynamics>/appdhttpsdk

Default path is usually /opt/appdynamics/appdhttpsdk (Linux) and  C:\AppDynamics\appdhttpsdk (Microsoft Windows).

Uninstall the Machine Agent

To stop the machine agent, see Start and Stop the Standalone Machine Agent.

To uninstall the agent, delete the installation directory.
