1 Oracle RAC Database 11g Documentation User Name = root Password = dks2010 Username = oracle Password = oracle Enterprise Manager user name = system Password = manager, profile = Normal Final Migration steps for ORCL RAC database and staging Sandb database: 1: Drop existing database ORCL & SANDB. 2: create new databases ORCL & SANDB. 3: update tnsnames.ora entry. 4:create tablespace and temp tablespaces: 5: Down production database. 6: open database and stop listener. 7:take export of full database through datapump: 8:create directory in new database for import. 9:import data using below command: impdp system/oracle full=y directory=test dumpfile= expproddata.dmp logfile=5_ap_impdp_log.log 10. check object_count_ list and db_link connections: 11.Change parameters values: alter system set memory_target=16g scope=spfile sid='*'; alter system set session_cached_cursors=70 scope=spfile sid='*'; alter system set open_cursors=10000 scope=both sid='*'; alter system set job_queue_processes=500 scope=both sid='*'; 12.Check no of processes: alter system set processes=500 scope=spfile sid='*'; 13.Check core dump creation: 14. Start archiving in both databases and increase recovery file size: 15. Configure backup through rman: crs_status Should like this: $ crs_stat -t Name Type Target State Host ora.flash.dg ora...up.type ONLINE ONLINE oracledb11 ora...esk2.dg ora...up.type ONLINE ONLINE oracledb11 ora...isk1.dg ora...up.type ONLINE ONLINE oracledb11
