Issue

  • When trying to upgrade a Liferay environment using a JNDI connection to the database the upgrade fails and produces errors. 
  • Auto upgrade portal properties ("upgrade.database.auto.run=true" and "schema.module.build.auto.upgrade=true") do not work with JNDI. 

Environment

  • DXP 7.4 

Resolution

If you are unable to immediately upgrade to a version containing the fix for LPS-197082, apply the following workaround:

 

  1. Open your portal-ext.properties file.

  2. Add the following property and leave the value blank: jdbc.default.driverClassName=

  3. Save the file and restart the Liferay server.

 

Setting this property to a blank value prevents the incorrect detection of Hypersonic, ensuring Liferay applies the upgrade.database.auto.run=true configuration during the next startup.
