OracleException ORA-02056 when using Oracle RAC

Post by crmall » Tue 16 Jun 2015 14:56

Error running with Oracle RAC

When running the application on an Oracle RAC I'm getting a lot of Exceptions:

Devart.Data.Oracle.OracleException ("ORA-02056: 2PC: k2srol: bad two-phase command number 2 from coord"). The default TransactionSetting is with TransactionScope TRUE.

How can I solve this?

dotConnect for Oracle supports RAC in the OCI mode only. In the OCI mode, all the actions are performed by Oracle Client, and dotConnect for Oracle only passes data to Oracle Client and gets the results.

The official ORA-02056 error description recommends contacting Oracle support. For more information, please refer to http://docs.oracle.com/cd/B28359_01/ser ... #ORA-01500
