How to avoid audit records with: BEGIN sys.dbms_xa.dist_txn_sync END; using audit_sys_operations=tru

Hi,

In our SLES enviroment with Linux 3.0.101 and Oracle 12.1.0.2.0 EE 64bit we have the following audit

settings, no unified auditing is used:

audit_file_dest=/oracle/orae220/base/admin/orae220/adump

audit_sys_operations=true

audit_syslog_level=''

audit_trail=XML, EXTENDED

The application uses JBoss and distributed transactions. Hence this is why i see in the audit

xml files massive entries of the form:

BEGIN sys.dbms_xa.dist_txn_sync END

How can i avoid that those type of records are written? There is no value in them.

Thanks for any hints. Regards,

Uwe
