Hello All,
I want to enable APOC trigger in my neo4j community edition instance in azure,
How do i install APOC plugin and enable triggers for remote connections
please help
@fcidkampl
there is no detail in the initial post to describe what version of Neo4j is in play here but
Installation - APOC Documentation is the v5.x install instructions for APOC.
Further
apoc.trigger - APOC Documentation describes all things apoc.trigger*
has any of this been tried?
Thank you for response @dana_canzano
I opened my neo4j community azure instance on neo4j desktop application
My neo4j community (remote connection) version on azure is 5.19.0
I have downloaded APOC jar 4.4.0.27 all into neo4jDesktop/Plugins folder
when i am trying to call below query
call apoc.triggger.list()
it produce below error
Failed to invoke procedure apoc.trigger.list: Caused by: java.lang.RuntimeException: Triggers have not been enabled. Set 'apoc.trigger.enabled=true' in your apoc.conf file located in the $NEO4J_HOME/conf/ directory.
the document says default value of trigger is false.
for enabling trigger in local DB the approach is different
but how to enable trigger for remote connection ????
a bit confused. the apoc-.jar that is in plugins/ should be of the same version as Neo4j.
If you are running Neo4j 4.4.x then apoc-4.4..jar would be appropriate. However if running Neo4j v5, then use a apoc-5.jar.
Also, as the error message states, the apoc.conf needs to have apoc.trigger.enabled=true. This apoc.conf is on the instance where Neo4j is running and in conf/
I explain what i have done & what i want to achieve
Step 1:
I created neo4j community edition resource on my azure portal (Version 5.19.0)
Step 2:
Then I opened neo4j desktop app and initiated remote connection
so i entered username as IP address with port and password which was asked at the time of creating resource.
Step 3:
Connection established now i can run query on my remote connection,
so i created nodes and relationships. its working perfectly
Step 4:
Now i want to enable APOC,
So i have installed APOC jar file (Version 5.19.0 - core) and placed into
.Neo4jDesktop/plugins folder
Now my concern is where i can see neo4j.conf file or apoc.conf file
so i can enable apoc.trigger.enable=true
on which folder do i create apoc.conf file.
for local dbms the file is located in .Neo4jDesktop/relate-data/dbmss/neo4jinstance-name/conf/file_name
for remote connection i cant see neo4j-instance-name at anywhere...
or neo4j.conf file.
is there any different approach to enable apoc trigger in this scenario
please guide us properly
& sorry for my poor english
Thank You
if you are connecting to a remote instance and you need APOC and triggers on the remote instance than you need APOC and triggers enabled on the remote instance.
Somehow Neo was installed on this remote instance?
if you run at the linux prompt
ps -eaf | grep java
this may return output similar to
ps -eaf | grep java

note the paths above are unique to my environment. Presumably you will have different paths.
For the entry above named
--config-dir=/home/neo4j/single/instance1/neo4j-enterprise-5.18.0/conf
you need to define a apoc.conf in this path with
apoc.trigger.enabled=true
and you also need to move the apoc* .jar into the plugins/ directory

Neo4j runs under Azure and running Windows?
Did you ? a coworker ? do they not know the path where it was installed?
Thank You Very Much @dana_canzano ..
It's worked
