Hi guys,

I have 2 database configured as primary and physical standby.
Both are configured using dataguard broker.In this configuration switchover works fine.

If i pull out network cable from primary.After that if i issue any command on DGMGRL prompt on standby it hangs for ever.
The commands I issue as 'show configuration verbose'.It hangs forever. and 'show site 'standby_site_name' status also hangs.
It does not comeup with success message.

is anybody have any idea whay is like that?

Regards,
Vipin Doshi

make sure your dr*.dat files in O_H/dbs directory on standby are intact and are in sync with primary with similar or later timestamp than primary
