Unable to connect Oracle server from google cloud DataFlow

I am trying to read data from Oracle server which is running in 'CST' timezone. My google DataFlow is running in 'us-central1' region. I am using Apache Beam-2.3.0 JDBCIO.read() method to read data from Oracle server. I am able to connect and read data from server using 'DirectRunner' but getting the following error in 'DataflowRunner' using ojdbc8 driver jar

Note: Connected and read data from server successfully using ojdbc6 driver in both DirectRunner and DataflowRunner. But I want to get it work using ojdbc8 driver jar.

The following is my datasourceConfiguration for JDBCIO

DataSourceConfiguration dataSourceConfiguration = JdbcIO.DataSourceConfiguration
    .create(options.getDriverName(), options.getJdbcUrl())
    .withUsername(options.getUsername())
    .withPassword(options.getPassword())
    .withConnectionProperties("timezone=CST");

Any inputs to make this connection successfull using ojdbc8 driver jar in 'DataflowRunner'?

It looks like the error (ORA-00604: error occurred at recursive SQL level 1 ORA-01882: timezone region not found is known and quite common with the Oracle JDBC drivers.

It happens when the the JDBC driver is not able, for some reason, to send the right Timezone ID to the server. After some investigation and searches across different sources (including other Stack Overflow cases such as this one or this other one), I have found different possible solutions, so let me summarize them here:

  • Make sure that you are using the latest available version of the ojdbc8 driver, because maybe there was something broken in the specific version you were using. Try to change to a different version and see if that works.
  • Try setting the default Timezone to your timezone before establishing the connection, as in Solution 2 below.
  • Add the configuration line in Solution 3 to the file oracle/jdbc/defaultConnectionProperties.properties.

Summarized solutions:

// Solution 2
TimeZone timeZone = TimeZone.getTimeZone("yourTimeZone");
TimeZone.setDefault(timeZone);

// Solution 3
oracle.jdbc.timezoneAsRegion=false
