Error Opening feature Class - Unable to create object class extension COM component

Hi

I am having 64 bit Oracle 11g R2 database server in Windows Server 2008 R2 operating System. As well as a another Application Server where Oracle Client 11g R2 64 bit, ArcSDE 10.1, ArcGIS 10.1 SP1 & ArcFM 10.1.1 has been installed.

I have imported dump data in oracle using impdp successfully then enable Enterprise Geodatabase using Database Management toolbox.

I am getting error while opening feature class from ArcCatalog / ArcMap,

Error opening feature class
Unable to create object class extension COM component
[UserName.FeatureClassName]

As per my observation this error is coming in only linear feature class. Rest other feature classes are working fine.
Please suggest.

Thanks in advance.

Regards
Ashish
