can anyone help me please i'm afraid to shutdown the primary database caus it may not start again.

i need your help please .. does anyone have any suggestions

hope you have open SR to oracle while waiting for some help in the forum.

Thanks,

the primary is working fine but i need at least steps to recreate it again

please consult your DBA who built the existing primary and standby sites. If you want to try your self there are bunches of documents available on the net. Google it and update the forum if you didn't find any thing.

Thanks,
