Hello Gurus

I have a two server say A and B. In A i m having the database name ta290 and B dta290 respectively. In the server A i have created the Standby Controlfile and copy the control file to server B as defined in initB.ora. I try to start the commend with

Alter database mount standby database.

It show the following error

SQL> startup nomount
ORACLE instance started.
