Greetings-

How do I use MongoDB in place of the default H2 database? Is it recommended that each Nuxeo node in a cluster use a SINGLE shared database(mongodb in this context) instance, as well as another sql database (postgres or something else) instead of h2? How do I actually confirm that Nuxeo is infact using MongoDB in this instance and not h2.

I'm in the process of propping up AWS in a clustered, cross-az single region model. The cluster has 2 nodes in 3 AZ's netting 6 nodes. I've also stood up MongoDB in a primary, secondary, seconday relationship, also cross az with a single mongos in a given AZ. I've also enabled GridFS in nuxeo.conf for the MongoDB BLOB store. I've also stood up an AWS ElasticCache (redis 2.8.23) also single node in a given AZ spanning the same 3 AZ's above.

I've confirmed that the nuxeo hosts are in clustered mode, also using the redis cache by looking at the redis cache for KEYS nuxeo, and I can see the different nodeID's as well as various session stores. I've also confirmed that in MongoDB I can use the nuxeo database, and see nuxeo and other tables.

Below is the contents of the existing mongo cluster. You can see that GridFS is being used below because of default.fs.chunks and default.fs.files tables are listed.

mongos> use nuxeo
switched to db nuxeo
mongos> show tables
default
default.fs.chunks
default.fs.files
quartz_calendars
quartz_jobs
quartz_locks
quartz_schedulers
mongos>

I've been following the documentation https://doc.nuxeo.com/nxdoc/mongodb/. about enabling the MongoDB database and it says “You must keep the template corresponding to your SQL database in nuxeo.templates, because the SQL database is still used for other things (directories, audit, etc.). “

If I look at default-repository-config I even see my db settings amongst other important items.

<component name="default-repository-config">
  <extension target="org.nuxeo.ecm.core.blob.BlobManager" point="configuration">
    <blobprovider name="default">
      <class>org.nuxeo.ecm.core.storage.sql.S3BinaryManager</class>
      <property name="path">/opt/nuxeo</property>
      <property name="key"></property>
    </blobprovider>
  </extension>
  <extension target="org.nuxeo.ecm.core.storage.mongodb.MongoDBRepositoryService"
      point="repository">
    <repository name="default" label="label.default.repository">      
<server>mongodb://primarydb01.companydomain.internal,secondarydb01.companydomain.internal,secondarydb02.companydomain.internal/?maxPoolSize=200</server>
      <dbname>nuxeo</dbname>
      <fulltext disabled="false" searchDisabled="false" />
      <cache enabled="true" maxSize="1000" concurrencyLevel="10" ttl="10" />
      <clustering id="167773350" enabled="true">
        <invalidatorClass>org.nuxeo.ecm.core.redis.contribs.RedisDBSClusterInvalidator</invalidatorClass>
      </clustering>
    </repository>
  </extension>
</component>

When I log into the Nuxeo console and view the Admin page I can clearly see that the h2 db is still enabled(see attached screenshot). Where did I go wrong?
