Abstract
This Knowledge Collection is a compilation of links to the most frequently accessed technotes and webcast replays dealing with Common Messaging Engine (ME) starting problems and their solutions.
Most of the Messaging Engine starting problems are caused by either configuration or runtime issues or both. Many of these problems can be resolved on your own very easily without calling IBM Support to open a Problem Management Record (PMR).
This document has good vital information about what are the most common reasons that could lead to a Messaging Engine not being able to start.

1. CWSIS1535E The messaging engine's unique id (ME_UUID) does not match that found in the data store. (1608913)
When trying to start a WebSphere Application Server Messaging Engine, it fails to start and in the SystemOut.log you see this error: CWSIS1535E: The messaging engine's unique id does not match that found in the data store.
2. Messaging Engine does not start. No errors or exceptions in the SystemOut.log related to the problem (1609567)
Your WebSphere Application Sever Messaging Engine does not start and you do not see any errors or exceptions in SystemOut.log; not even messages indicating an attempt to start the Messaging Engine.
3. Messaging Engine does not start. Exception: CWSIS1524E, specified data source not found. (1609726)

5. CWSIS1519E error occur when Messaging Engine failed to obtain lock on failover in clustering environment (1608885)
Your WebSphere Application Server Message Engine (ME1) did not release a data store lock when it failed. Now a new instance of the Message Engine (ME2) can not obtain the lock and issues message CWSIS1519E: Messaging engine MyCluster.000-MyBus cannot obtain the lock on its data store after fail over to other server in a clustering environment.
6. The messaging engine's instance unique id (INC_UUID) does not match that found in the data store in clustering fail over environment (1608951)
You are seeing the following error message generated in the SystemOut.log during a WebSphere Application Server clustering fail over scenario for your Messaging Engine.
CWSIS1535E: The messaging engine's unique id does not match that found in the data store. ME_UUID=ME1, INC_UUID=INC1, ME_UUID(DB)=ME1, INC_UUID(DB)=INC2 (ME_UUID is same, where as INC_UUID is different in this case)
7. The messaging engine's unique ID does not match that found in the data store (1328985)
In WebSphere, if a bus member is removed and re-added to the same bus, the message engine will not start and errors will be seen in the systemout logs.

CWSIS0002E: The messaging engine encountered an exception while starting. Exception: com.ibm.ws.sib.msgstore.PersistenceException: CWSIS1501E: The data source has produced an unexpected exception: java.sql.SQLException: SQL30082N Attempt to establish connection failed with security reason "24" ("USERNAME AND/OR PASSWORD INVALID"). SQLSTATE=08001 DSRA0010E: SQL State = 08001, Error Code = -30,082
11. CWSIT0019E and CWSIT0103E errors: No suitable messaging engine is available errors returned to application even though Messaging Engine is running (1608705)
CWSIA0241E, CWSIT0019E and CWSIT0103E errors are returned to client . These errors are seen in the SystemOut.log even though Messaging Engine (ME) is running in one of the messaging cluster servers.
12. WebSphere Application Server Service Integration Bus messaging engine startup fails with ORA-28000 error (1610676)
After restarting WebSphere Application Server (WAS), the messaging engine fails to start and throws the following error:
