Goal

How to restart LSH/DMW services successfully?

Note: This document is applicable only for LSH/DMW 2.5.2 and later versions. Please refer to Doc ID 2250628.1 for LSH/DMW 2.5.1 and prior versions.

There is no single command to startup LSH/DMW. It includes different processes/services with dependencies between them. If they are not stopped/started in the correct order, you may hit unexpected issues later, i.e., defunct processes alive in memory that may not permit the new/fresh ones are started up successfully, or services starting up with incorrect values/environment settings.

The technical details shared in this document are from DMW Installation Guide, i.e., DMW Release 2.4 information is in Chapter 3.12 Restart the WebLogic Server.

In summary, you need to apply below order to accomplish a successful restart:

These KM NOTE steps only apply when you are doing shutting down activity explicitly.

To Shutdown LSH/DMW:

  1. Enable DMW Maintenance Mode
  2. Stop Middle Tiers (DMW first then LSH)
  3. Stop OWB services (CRITICAL: Make sure you wait 10 minutes before starting up OWB services)
  4. Stop DP Servers
  5. Purge OWB Execution Audit Tables
  6. Shutdown the TNS listener and the DB

To start up LSH/DMW, you practically apply the reverse order:

  1. Start the DB and then, the TNS listener (CRITICAL: Make sure you wait 10 minutes before doing next step -> starting up OWB services)
  2. Start OWB Services
  3. Start DP Servers
  4. Start Middle Tiers (LSH first then DMW)
  5. Disable DMW Maintenance Mode

This document explains above with step by step generic instructions, but feel free to create your custom shell script(s) if it facilitates this task.
