[FangZhen_TAO]

This article briefly introduces how to perform a clean-up to restore mistakenly deleted features for a damaged Remote Engine, without reinstalling and pairing the entire engine.

Before you begin

Your Remote Engine version must be v2.12.14 onwards.

How To

Solution 1: Graceful clean-up to repair a damaged Remote Engine

1. Stop the engine and please follow documentation about  running the graceful shutdown process of Remote Engine.
2. Remove the <RE_installation>/data/cache folder and restart the engine.
3. 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, please execute that script with the clean option to restart your engine. For example,

   ./trun clean

   The graceful cleanup process automatically identified the missing features required by a paired engine and re-install them.

Solution 2: Clean Remote Engine Cache

1. Stop remote engine

2. Delete the content in tmp folder <RE_installation>/data/tmp

3. Delete the content in cache <RE_installation>/data/cache
