hi all, This is the first time, I am going to put one production server, which is running in Active-Passive cluster, in archivelog mode from noarchive log mode. As I said since this is the first time , I am going to do this , so I don know what are the changes required. My plan is as : 1) setting log_archive_dest,log_archive_format & log_archive_start parameters in init<sid>.ora/spfile<sid>.ora on both the nodes 2) connecting to oracle server with sys/pass@string as sysdba 3) shutting down the database using SHUTDOWN IMMEDIATE 4) starting the database normally using STARTUP Do I need to do something else??? Plz. sugges. -- Thanks & Regards, T. Onkar Nath OneAPPS Enterprise Technology Pvt. Ltd. to_onkar@xxxxxxxxx onkarnath.tiwary@xxxxxxxxx
