Atomikos Forum

Hi am facing the following error, when trying to run a standalone application using Atomikos for XA transaction.

Please assist.I have read other posts and tried checking for any loc files created, but i could not find any loc files to be deleted.

Error: the specified log seems to be in use already. Make sure that no other instance is running, or kill any pending process if needed.
java.lang.RuntimeException: Log already in use
    at com.atomikos.icatch.standalone.UserTransactionServiceImp.createDefault(UserTransactionServiceImp.java:205)


I have used below configuration to pick the jta.properties

Logs also says:

Error starting bean with name userTransactionService defined in DaoConfig.xml: Invocation of init method failed; nested exception is java.lang.IllegalStateException: Can'y overwrite cause.

Hi Does anyone has any info regarding this error ? It has led us to complete XA transaction configuration to revert.

Hi,

Check to make sure that no two JVMs are started with the same transaction log folder / file name.
