How to restart LSH/DMW services successfully?

Note: This document is applicable only for LSH/DMW 3.0 Version.

Please refer to Doc ID 2250628.1 for LSH/DMW 2.5.1 and prior versions and Doc ID 2689508.1 for LSH/DMW 2.5.2 Version

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 3.0 Installation Guide, Chapter 3.3.9 Restart the WebLogic Server.

In summary, you need to execute below steps in order to accomplish a successful restart:

Below steps from this KM Document only apply when you are shutting down explicitly.

To Shutdown LSH/DMW:

Enable DMW Maintenance Mode
Stop Middle Tiers (DMW first then LSH)
Stop DP Servers
Shutdown the TNS listener and the DB

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

Start the DB and then, the TNS listener (CRITICAL: Make sure you wait 10 minutes before doing next step -> Start DP Servers)
Start DP Servers
Start Middle Tiers (LSH first then DMW)
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.
