Environment

Release : 10.x

Component : APM 

Cause

Data files are flagged as bad when a corruption is detected in the file by the Enterprise Manager. The file is then renamed and ignored. This problem is usually caused when file system problems are encountered such as disk errors or file system full situations.

Resolution

First identify any underlying cause by reviewing the IntroscopeEnterpriseManager.log files - if the reason is not obvious then raise a case with support for assistance.

Once the cause has been identified and resolved then as it is not possible to repair these files the only action is remove them.
