Delete files following removal of a messaging engine

Remove a messaging engine from the configuration does not automatically delete the file store files. We must also find and delete the log file, the permanent store file, and the temporary store file from the disk to reclaim disk space.

Files comprising a file store still remain when the messaging engine is deleted. If you are using the default values for the file store directory names, you can delete and then re-create a messaging engine with the same name without manually removing the files. This is due to the presence of the universal unique identifier (UUID) of the messaging engine in the default log and store directory names of a file store.

For example, if the deleted messaging engine is called messagingengine0, and the new one is called messagingengine1, then the log file in the old file store is:

C:\{USER_INSTALL_ROOT}\filestores\..\messagingengine0\..\logfile

The log file in the new files store is:
C:\{USER_INSTALL_ROOT}\filestores\..\messagingengine1\..\logfile

The two log files coexist in the same file stores directory. You do not have to delete the old files.


Procedure

  1. Locate the directory in which your old file store log files and store files are stored.
  2. Delete the redundant files by using the facilities of the operating systems.


Results

After deleting the files left by the redundant file store, free disk space becomes available to your file system.
