Cannot access database created from dump file

Neo4j Graph Platform Import / Export
1

Hi,

I'm using neo4j 5.6 for Linux and imported a database from a dump file but cannot access the database using cypher queries.

I import the database named "spoke" using:

./bin/neo4j-admin database load --from-path=/grand/tarak_files/KG/data/ spoke
Done: 275 files, 40.24GiB processed.

and the database shows up in the "data/databases" directory:

.../data/databases> ls
neo4j  spoke  store_lock  system

Still, when I do "SHOW DATABASES" within a cypher shell, the database "spoke" doesn't appear:

neo4j@neo4j> SHOW DATABASES yield name;
+----------+
| name     |
+----------+
| "neo4j"  |
| "system" |
+----------+

2 rows

Can you please suggest what needs to be done to work on the "spoke" database?

Note: The dump file was created using neo4j 5.6 so there shouldn't be any incompatibility issues (it has been successfully imported to a database on neo4j 5.6 desktop version).

Thanks,
Tarak

Restore a database dump - Operations Manual states

If you are replacing an existing database, you have to shut
 it down before running the command. If you are not replacing 
an existing database, you must create the database (using 
CREATE DATABASE against the system database) after the 
load operation finishes.

did you run create database spoke; ?

@dana_canzano Thank you very much for the response! When I try creating the database against the system database, I get the following error:

neo4j@neo4j> :use system
neo4j@system> CREATE DATABASE spoke;
Unsupported administration command: CREATE DATABASE spoke

Also, I'm not replacing an existing database as you can see below that SHOW DATABASES doesn't show the existence of the "spoke" database:

neo4j@system> SHOW DATABASES yield name;
+----------+
| name     |
+----------+
| "neo4j"  |
| "system" |
+----------+

2 rows

Thanks,

HI @dana_canzano , I could finally get the new database created by adding " dbms.default_database=spoke in the conf/neo4j.conf file as suggested by some other online posts.

Thanks,

Thanks for the update. And yes if you are using Neo4j Community edition, which only supports a single database + system database, whereas Neo4j Enterprise editions allows for multiple databases then the actions you have taken are correct
