ERROR IN RECOVERY com.atomikos.datasource.ResourceException: Error in recovery at com.atomikos.datasource.xa.XATransactionalResource.recover(


Oracle Error in Recovery

When Oracle is not properly configured for XA then the following error may show up in the Atomikos console file:

Error in recovery

Solution: make sure that Oracle is configured for XA - as in ConfiguringOracle, and that the userid for which XA is required has access rights on the XA catalog tables (explained in ConfiguringOracle as well).

AtomikosDataSourceBean example

AtomikosDataSourceBean ds = new AtomikosDataSourceBean();
Properties p = new Properties();
p.setProperty ( "user" , "java" );
p.setProperty ( "password" , "java" );
p.setProperty ( "URL" , "jdbc:oracle:thin:@localhost-xe:1521:XE" );
ds.setXaDataSourceProperties ( p );


Oracle 9.2 and Oracle 10 are both working fine. It is highly recommended to use the latest Oracle 10 JDBC driver even when connecting to Oracle 9 databases.

Oracle's DBMS must be configured with extra packages before you can use it with XA:

grant select on sys.dba_pending_transactions to <user name>;
grant select on sys.pending_trans$ to <user name>;
grant select on sys.dba_2pc_pending to <user name>;
grant execute on sys.dbms_system to <user name>;

Oracle 10.2 and lower

NOTE: this tip was written with Oracle DBMS version

How can you know if your Oracle server is correctly configured for XA?

The simplest and usually the most effective way is the following:

  • logon to SQLPlus (or use another tool if you like); make sure to use the user/password that you are using for your application

  • execute the query: select * from SYS.DBA_PENDING_TRANSACTIONS;

If this works then XA is configured.

If not then you should do one or all of the following:

  1. run the oracle scripts 'initxa.sql' and 'xaview.sql' (or ask your DBA to do this for you).

  2. ask your DBA to grant select rights (to your user) on SYS.DBA_PENDING_TRANSACTIONS

  3. for the driver ojdbc14.jar, you also need execute rights on SYS.DBMS_SYSTEM

The last step is NOT needed for the older (JDK 1.2) drivers in classes12.jar

Oracle 11 and higher

For Oracle 11, you no longer need execute rights on SYS.DBMS_SYSTEM
