Section

Configure CRC data source

Earlier in during the data installation you created new crcdata tables and in order for the CRC to communicate with the database it needs to know where these tables reside. This information is configured in the crc-ds.xml file.

Things to keep in mind when configuring your datasources:

  • The crcdata tables were created during the Data Installation stage of this document.
  • The other database tables (hivedata, pmdata, etc.) were created when setting up your i2b2 database (demo environment - i2b2 Installation Guide).
  • The CRCBootStrapDS points to the data source for your CRC_DB_LOOKUP table which is a hivedata table.
    • The <user-name> and <password> need to match the database user you set up for your hivedata. In the i2b2 demo database this is i2b2hive and demouser.
  • The QueryToolDemoDS points to the data source for your demodata tables.
    • The <user-name> and <password> need to match the database user you set up for your demodata. In the i2b2 demo database this is i2b2demodata and demouser.
  • The <connection_url> needs to have the following:
    • The correct JDBC information for your type of database.
    • The correct location of the database containing your crcdata tables. (These may or may not reside in the same location as your hivedata)
  • Both the <driver-class> and <driver> need to accurately reflect the type of database you are connecting to.

 

Steps to configure data sources

The following steps define how to configure your data sources for the CRC Cell. These steps include example configurations for Oracle, PostreSQL and SQL Server.
Info
titleReminder

As part of the i2b2 on OMOP project there are specific crcdata tables that were created earlier in this installation process. Other than the metadata table, all other tables were created when you initially setup your i2b2 database using the standard i2b2 Installation Guide.

Steps to configure data sources

The following steps define how to add the data source for the new crcdata tables. The steps include example configurations for Oracle, PostgreSQL, and SQL Server.

Warning
titleWarning

Only 1 CRCBootStrapDS can reside in the crc-ds.xml file.

  • If your file does contain the CRCBootStrapDS you can proceed with this section of the installation guide.
  • If your file does not contain the CRCBootStrapDS, you can go to the Data Source Configuration chapter of the i2b2 Installation guide.

2. Open the crc-ds.xml file to configure your data sources.

 

Step 2: Add a new datasource and update the following information: (see examples shown below)

    •  Set the jndi-name and pool-name to OMOP_CDM_{ORACLE | POSTGRESQL | SQLSERVER}.
    •  Update the connection-url to point to the location of the database containing the crcdata tables.
    •  Update the user-name and password to accurately reflect the database user you setup during the Data Installation.
    •  Verify the jdbc driver in the connection-url, driver-class, and driver accurately reflect the type of database you are connecting to.

Step 3: Save the changes and close the file.

The above example is for an Oracle database. If your database is SQL Server or PostgreSQL then you will need to copy the <datasource> section for your type database connection. Do not use this one as it will not work.
