Neo4j

mahesh_jayachan · ‎01-06-2023

In the docker environment. I am trying to upgrade the neo4j version from 4.4.3 to 5.2.0

I am facing the below error

Failed to read config /var/lib/neo4j/conf/neo4j.conf: Unrecognized setting. No declared setting with name: apoc.export.file.enabled. Cleanup the config or disable 'server.config.strict_validation.enabled' to continue.

In neo4j.conf file I have commented on the below line

apoc.export.file.enabled even though am getting the same error.

@mahesh_jayachan

Thanks for reporting and I have reproduced the failure such that including apoc.export.file.enabled=true, and to which this is a valid parameter, in your conf/neo4j.conf, and with server.config.strict_validation.enabled defined as true ( note in 5.x the default was changed from its previous FALSE to TRUE ), that neo4j will fail to start.

Can you add to your conf/neo4j.conf

server.config.strict_validation.enabled=false

restart and let me know if Neo starts and if you are able to export via APOC.

I will report this to engineering for further analysis

@mahesh_jayachan

if you move apoc.export.file.enabled=true from conf/neo4j.conf to conf/apoc.conf ( you may need to create said file ) does this allow for successful Neo4j start. From a doc perspective APOC 5x doc https://neo4j.com/docs/apoc/5/config/#config-reference indicates to put the apoc* config settings in conf/apoc.conf

# Memory Settings
#********************************************************************
#
# Memory settings are specified kilobytes with the 'k' suffix, megabytes with
# 'm' and gigabytes with 'g'.
# If Neo4j is running on a dedicated server, then it is generally recommended
# to leave about 2-4 gigabytes for the operating system, give the JVM enough
# heap to hold all your transaction state and query context, and then leave the
# rest for the page cache.

# Java Heap Size: by default the Java heap size is dynamically calculated based
# on available system resources. Uncomment these lines to set specific initial
# and maximum heap size.
#server.memory.heap.initial_size=512m
#server.memory.heap.max_size=512m

# The amount of memory to use for mapping the store files.
# The default page cache memory assumes the machine is dedicated to running
# Neo4j, and is heuristically set to 50% of RAM minus the Java heap size.
#server.memory.pagecache.size=10g

# Limit the amount of memory that all of the running transaction can consume.
# The default value is 70% of the heap size limit.
#dbms.memory.transaction.total.max=256m

# Limit the amount of memory that a single transaction can consume.
# By default there is no limit.
#db.memory.transaction.max=16m

# Transaction state location. It is recommended to use ON_HEAP.
# db.tx_state.memory_allocation=ON_HEAP

#*****************************************************************
# Network connector configuration
#*****************************************************************

# With default configuration Neo4j only accepts local connections.
# To accept non-local connections, uncomment this line:
#server.default_listen_address=0.0.0.0

# You can also choose a specific network interface, and configure a non-default
# port for each connector, by setting their individual listen_address.

# The address at which this server can be reached by its clients. This may be the server's IP address or DNS name, or
# it may be the address of a reverse proxy which sits in front of the server. This setting may be overridden for
# individual connectors below.
#server.default_advertised_address=localhost

# You can also choose a specific advertised hostname or IP address, and
# configure an advertised port for each connector, by setting their

# SSL policy configuration
#*****************************************************************

# Each policy is configured under a separate namespace, e.g.
# dbms.ssl.policy.<scope>.*
# <scope> can be any of 'bolt', 'https', 'cluster' or 'backup'
#
# The scope is the name of the component where the policy will be used
# Each component where the use of an ssl policy is desired needs to declare at least one setting of the policy.
# Allowable values are 'bolt', 'https', 'cluster' or 'backup'.

# E.g if bolt and https connectors should use the same policy, the following could be declared
# dbms.ssl.policy.bolt.base_directory=certificates/default
# dbms.ssl.policy.https.base_directory=certificates/default
# However, it's strongly encouraged to not use the same key pair for multiple scopes.
#
# N.B: Note that a connector must be configured to support/require
# SSL/TLS for the policy to actually be utilized.
#
# see: dbms.connector.*.tls_level

# SSL settings (dbms.ssl.policy.<scope>.*)
# .base_directory Base directory for SSL policies paths. All relative paths within the
# SSL configuration will be resolved from the base dir.

# .private_key A path to the key file relative to the '.base_directory'.
#
# .private_key_password The password for the private key.

#
# .trusted_dir A path to a directory containing trusted certificates.
#
# .revoked_dir Path to the directory with Certificate Revocation Lists (CRLs).
#
# .verify_hostname If true, the server will verify the hostname that the client uses to connect with. In order
# for this to work, the server public certificate must have a valid CN and/or matching
# Subject Alternative Names.
#
# .client_auth How the client should be authorized. Possible values are: 'none', 'optional', 'require'.
#
# .tls_versions A comma-separated list of allowed TLS versions. By default only TLSv1.2 is allowed.
#
# .trust_all Setting this to 'true' will ignore the trust truststore, trusting all clients and servers.
# Use of this mode is discouraged. It would offer encryption but no security.
