Engine Clean-up Tool

Sometimes, during the engines downloading/deployment process, some of them may remain in "failed" or "permanently failed" status. In that case, you could perform an engine clean-up by using MetaDefender Core built-in engine sweeper tool:

• Locate the tool in MetaDefender Core installation folder named ometascan-engine-sweeper

Usage: ometascan-engine-sweeper [options]

MetaDefender Core 4.19.x database information to connect

• Host and port: Specified while installing Core 4.19.0. In default installation option, MetaDefender Core setups local and connect to PostgreSQL server at localhost via port 5432
• Username: Specified while installing Core 4.19.0. In default installation option, MetaDefender Core uses username postgres
• Database name: MetaDefender Core metadefender_core_xxxxxx - whereas xxxxxx is the 6 characters in lower case following product code name (Windows: MSCW, Linux: MSCL) in your current Deployment ID.

Example usages

Assuming we will connect to a local PostgreSQL server with following info:

• localhost via port 5432
• username = postgres
• database name = metadefender_core_lrmgvs

Example 1: List all installed engines

note

Making sure to use “-B” parameter option if that is a local PostgreSQL server

Then the tool requires you to input PostgreSQL server password for MetaDefender Core (specified while installing MetaDefender Core)

Example output:

Example 2: Remove engine package and database package of Archive engine (e.g. 7z_13_windows)

Note: Making sure to use “-B” parameter option if that is a local PostgreSQL server

Example output:

Example 3: Remove engine only (retain its database)

Note: Making sure to use “-B” parameter option if that is a local PostgreSQL server

Example output:

Example 4: Remove all engines

Note: Making sure to use “-B” parameter option if that is a local PostgreSQL server

Example output:
