APOC is only partially installing its extension in neo4j (one procedure)

I downloaded apoc-3.1.0.3-all.jar and placed it in the plugins for my windows7 Neo4J 3.1.1 system.

C:\Users>java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

Killed the Neo4J process on the computer, and then restated the server.

I am only seeing one apoc procedure listed, others give an error about missing procedure. ThereNo sign of errors in the neo4j log. I tried unblocking the jar, and restarting the server. No luck.

I have no problem with doing

Call db.schema()

But something as simple as:

CALL apoc.help("help")

will result in a

There is no procedure with the name `apoc.help` registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.

What am I doing wrong, I assume it must be me!)

$call dbms.procedures

Solution 1:

There is a poorly documented difference between installing neo4j using an installer (which is most common) versus from a zip or tar file.

(A) When you install neo4j using an installer, the installer configures the neo4j server to look for the plugins folder in the database folder (i.e., under the default.graphdb folder).

(B) When you install neo4j from a zip or tar file, the neo4j server will look for the plugins folder in the neo4j installation folder (for example, the plugins folder should be a sibling of the neo4j bin folder).

It sounds like (A) applies to you.

Solution 2:

From what I remember, you have to create a plugins directory into your graph.db directory, put the apoc jar, and restart you server.

Otherwise you can specify the dbms.directories.plugins in neo4j.conf file.

Solution 3:

The answers by @cybersam and @logisima are absolutely correct. However, since I'm using a Red Hat Linux specifically Oracle-7, I had to add an additional step to it as well. This is how I got it working

1. Download the apoc-<version>.jar into the /var/lib/neo4j/plugins directory
2. chown neo4j:neo4j apoc-<version>.jar
3. chmod 755 apoc-<version>.jar
4. Open the neo4j.conf at /etc/neo4j/neo4j.conf and replace the line #dbms.security.procedures.whitelist=apoc.coll.*,apoc.load.* with dbms.security.procedures.whitelist=apoc.coll.*,apoc.load.*,apoc.* and save it.
5. Restart the Neo4j service by issuing the command systemctl restart neo4j

Note: Make sure that you have the right version of apoc jar downloaded. I'm using the neo4j version 3.5.5 and the apoc jar version I'm using is apoc-3.5.0.3-all.jar. Alos make sure that you have the dbms.directories.plugins=/var/lib/neo4j/plugins uncommented in the /etc/neo4j/neo4j.conf
