Cannot connect to Local database on windows7 laptop.
tnsping comes as OK but sqlplus hangs.
Oracle SID is ORCL and these services are up -

OracleServicesORCL
OracleOraDb11g_home1TNSListener

but "Oracle ORCL VSS Writer Service" is not coming up.
I am able to connect to other databases in the network but not to my local DB instance.

Need help to resolve this !

thanx
