adapters.os_xml file got corrupted, Probably the due to abrupt server restart.


  1. Go to $DOMAIN_HOME/config/fmwconfig/ovd/default/
  2. Rename corrupted adapters.os_xml
  3. Copy adapters.os_xml from $MW_HOME/oracle_common/modules/oracle.ovd/templates/ to $DOMAIN_HOME/config/fmwconfig/ovd/default/
  4. Restart the services



Problem2 : Oracle 12c report on Windows service not starting getting below error on windows
REP-52266: The in-process Reports Server rep_wls_reports_server failed to ———-BEGIN server-side stack trace———- org.omg.CORBA.OBJECT_NOT_EXIST: vmcid: SUN minor code: 1004 completed: No

CAUSE could happen after the recent system changes. temp folder used by default report temp path on registry not accessible

The issue was with windows registry parameter for Report tmp path.

The old path was not visible to Oracle service at report calling time, updated new path on registry for report_tmp


Edit registry “E:\Oracle\report_temp” instead of default windows tmp path, windows default tmp path changes

No folder permission specified on rwserver.conf.

Amened the configuration file rwserver.conf with below
