Re: HDR on Informix

Here are simple steps for implementing an HDR. 1. Create a secondary instance that is identicle to the primary instance(your main instance) A. Please please make sure that the SERVERNUM for the secondary is different from the primary. B. Informix recomends that the two servers have same hardware configuration and parameters setting. 2. Perform archive level zero on primary server, then use the archive to do physical restore (ontape -p) onto the secondary server. Reminded that the database will be in fast recovery mode until you turn initialize HDR and all logical logs in sync. 3. Turn on HDR on primary. A. onmode -d primary secondary_tcp. "Secondary_tcp" is your secondary server to which you primary is replicating the database. 4. Turn on HDR on the secondary. A. onmode -d secondary primary_tcp. "primary_tcp" is your main database server from which your secondary database is replicating the database. CAUTION: Primary sever will experience abnormally long check point when it syncs the last logical log.
