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

Answer
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.
