The following situation happens in Windows Operating System, it does not happen in Linux or Unix systems. In Windows Operating systems DLLs are used. Oracle uses the NetVault Backup orasbt.dll, which represents the Media Management Library. On occasions, if an error occurs, or a job is aborted, this could cause the NetVault Backup orasbt.dll to exit. In some situations, even the NetVault Backup orasbt.dll has exited, the handle that Oracle maintains with the DLL is not released. In these situations when you try to allocate another channel, Oracle instead of opening a new handle to orasbt.dll, Oracle will try to access the orasbt.dll using the previous handle that was already pointing to a DLL which had already exited. And that is the error that you see.
In order to release the handle that Oracle has Oracle Service needs to be restarted.
Start -> Administrative Tools -> Services; then look for a Service named OracleService<oracleSID> (for example, OracleServiceGLONTANA), then Restart.
This problem is being addressed in BUG 21345 see future NetVault and Oracle plugin release notes to track this bug
