This script is useful when multiple databases enter a quarantined state. You are first of all required to fix the underlying issue and afterwards it is necessary to lift the quarantine status of the databases so that read/write operations can be performed for the database on this instance.

During the unquarantine process, dbms.quarantineDatabase() allows only one database as a parameter which needs to be lifted from quarantine status at a time.

In the system database, it's not possible to pass the output of one cypher query to another directly.
This script saves time by streamlining the process of getting quarantined database details and lifting by using dbms.quarantineDatabase()

What does this script do - 

1. Connect to Neo4j and get the list quarantined databases.
2. Go to through each databases and run  "CALL dbms.quarantineDatabase($db,false);"
3. Script has a wait time of 10 seconds in subsequent calls of quarantineDatabase procedure.
4. Script is applicable for linux servers only.

What you need to do -

1. Download and extract attached zip file
2. Edit config.txt with username, password and provide bolt connection URL of the neo4j instance where databases are in quarantined state.
3. Run the script - ./lift.sh
