Perform a graceful cleanup to restore mistakenly deleted features for a damaged
Remote Engine, without reinstalling and pairing the entire engine.
When pairing an engine, required features are installed. Any circumstance that leads to the
loss of these features prevents your engine from working correctly. If the loss of features
has occurred, performing a graceful cleanup helps automatically re-install the lost
features upon the restart of the engine.
Before you begin
- Your Remote Engine version must be v2.12.14 onwards.
Procedure
-
Stop the engine. See Running the graceful shutdown process of Remote Engine for more
details.
-
Remove the <RE_installation>/data/cache folder and restart
the engine.
Alternatively, if your engine was installed using an archive delivery and used to
be started by one of start-up scripts from
<RE>/bin, such as
start,
karaf,
trun,
or
run, execute that script with the
clean option
to restart your engine, for example,
./trun clean
Results
The graceful cleanup process automatically identified the missing features required by
a paired engine and re-install them.
