Waiting for changelog lock....

During start-up, the following messages may appear in the cascade.log file and prevent Cascade Server from starting:

...
Waiting for changelog lock....
Waiting for changelog lock....
Waiting for changelog lock.... 
...

To see which machine has locked the Cascade Server database, execute the following SQL query:

select * from DATABASECHANGELOGLOCK;

Check the lockedby column to see who locked the table. Generally, the lock will be from the local machine.

If this is the case (and no other machine has a lock on the database), the record should be updated by executing the following query:

update DATABASECHANGELOGLOCK 
set locked=0, lockgranted=null, lockedby=null 
where id=1

After updating this record Cascade Server should start up again without any problems.
