DSRP - Relational Database Storage Resource Provider

When AEM Communities is configured to use a relational database as its common store, user generated content (UGC) is accessible from all author and publish instances without the need for synchronization nor replication.

See also Characteristics of SRP Options and Recommended Topologies.

• MySQL, a relational database
• Apache Solr, a search platform

A MySQL installation may be shared between enablement features and common store (DSRP) within the same connections pool by using different database (schema) names and also different connections (server:port).

For installation and configuration details, see MySQL Configuration for DSRP.

A Solr installation may be shared between the node store (Oak) and common store (SRP) by using different collections.

If both the Oak and SRP collections are used intensively, a second Solr may be installed for performance reasons.

For production environments, SolrCloud mode provides improved performance over standalone mode (a single, local Solr setup).

For installation and configuration details, see Solr Configuration for SRP.

The Storage Configuration console allows for the selection of the default storage configuration, which identifies which implementation of SRP to use.

On author, to access the Storage Configuration console

• sign in with administrator privileges
• from the main menu
  • select Tools (from the left hand pane)
  • select Communities
  • select Storage Configuration
    • as an example, the resulting location is:http://localhost:4502/communities/admin/defaultsrp

• select Database Storage Resource Provider (DSRP)
• Database Configuration
  • JDBC datasource name
    name given to MySQL connection
    must be the same as entered in JDBC OSGi configuration
    default : communities
  • Database name
    name given to schema in init_schema.sql script
    default : communities
• SolrConfiguration
  • Zookeeper Host
    Leave this value blank if running Solr using the internal ZooKeeper. Else, when running in SolrCloud mode with an external ZooKeeper, set this value to the URI for the ZooKeeper, such as my.server.com:80
    default :  <blank>
  • Solr URL
    default : http://127.0.0.1:8983/solr/
  • Solr Collection
    default : collection1
• select Submit

DSRP must be identified as the common store on all author and publish instances.

To make the identical configuration available in the publish environment :

• on author :
  
  • navigate from main menu to Tools > Operations > Replication
  • double-click Activate Tree
  • Start Path :
    • browse to /etc/socialconfig/srpc/
  • ensure Only Modified is not selected.
  • select Activate

For information regarding users, user profiles and user groups, often entered in the publish environment, visit

• User Synchronization
• Managing Users and User Groups

To reindex DSRP Solr, follow the documentation for reindexing MSRP, however when reindexing for DSRP, use this URL instead: /services/social/datastore/rdb/reindex

For example, a curl command to re-index DSRP would look like this:
