About the Custom SQL Connector

The Custom SQL Connector enables Incorta to access data stored in any SQL database. It is recommended that this connector be used when a dedicated Incorta database connector does not already exist. You can access the data you want with a standard SQL query. The Custom SQL connector supports the following Incorta-specific functionality:

Custom SQL Connector Updates

This section is to explore the updates in the newer versions of the Custom SQL connector available on the Incorta connectors marketplace.

In order to get the newer version of the connector, please update the connector using the marketplace.

Deploy the JAR file

The Custom SQL connector requires that you have a custom JDBC JAR file for the database vendor. The following is a generic example

• company.jdbc.jar

Please contact Incorta Support to assist you with deploying the JAR on an Incorta Cloud cluster.

For an On-Premises cluster, a System Administrator with root access will need to copy the JDBC driver JAR file of the database to each Incorta Node in an Incorta cluster. A CMC Administrator will need to restart the Analytics and Loader Services in the cluster.

Here are the steps to copy the JAR file to standalone Incorta cluster:

• Download the JDBC driver JAR file from the database vendor.
• Secure copy the company.jdbc.jar file to the host. Here is an example using scp:

Copy
INCORTA_NODE_HOST=100.101.102.103
INCORTA_NODE_HOST_PEM_FILE="host_key.pem"
INCORTA_NODE_HOST_USER="incorta"
CUSTOM_JDBC_JAR_FILE="company.jdbc.jar"

cd ~/Downloads
scp -i ~/.ssh/${INCORTA_NODE_HOST_PEM_FILE}  ${CUSTOM_JDBC_JAR_FILE} ${INCORTA_NODE_HOST_USER}@${INCORTA_NODE_HOST}:/tmp/

• Secure shell into the host

Copy
ssh -i ~/.ssh/${INCORTA_NODE_HOST_PEM_FILE} ${INCORTA_NODE_HOST_USER}@${INCORTA_NODE_HOST}

• Copy the company.jdbc.jar to the IncortaNode/extensions/connectors/shared-libs directory in bash shell

Copy
INCORTA_INSTALLATION_PATH=/home/incorta/IncortaAnalytics
CUSTOM_JDBC_JAR_FILE="company.jdbc.jar"
cp /tmp/${CUSTOM_JDBC_JAR_FILE} $INCORTA_INSTALLATION_PATH/IncortaNode/extensions/connectors/shared-libs/${CUSTOM_JDBC_JAR_FILE}

Restart the Analytics and Loader Services

Here are the steps to restart the Analytics and Loader Services in an Incorta Cluster from the Cluster Management Console (CMC).

• As the CMC Administrator, sign in to the CMC.
• In the Navigation bar, select Clusters.
• In the cluster list, select a Cluster name.
• Select the Details tab, if not already selected.
• In the footer, select Restart.

Here are the steps to view the physical schema diagram using the Schema Diagram Viewer:

• Sign in to the Incorta Direct Data Platform™.
• In the Navigation bar, select Schema.
• In the list of schemas, select the Custom SQL schema.
• In the Schema Designer, in the Action bar, select Diagram.

Load the physical schema

Here are the steps to perform a Full Load of the Custom SQL physical schema using the Schema Designer:

• Sign in to the Incorta Direct Data Platform™.
• In the Navigation bar, select Schema.
• In the list of schemas, select the Custom SQL schema.
