RE: how to rename a database SID
Title: how to rename a database SID Uday: You forgot one important step. In the 'create controlfile' command line, where you change the database SID you must add the word 'SET'. For example, if the trace file was created as... CREATE CONTROLFILE REUSE DATABASE "OLDSID" NORESETLOGS ARCHIVELOG ...then the new line must be changed to... CREATE CONTROLFILE REUSE SET DATABASE "NEWSID" RESETLOGS ARCHIVELOG HTH, Mike --- === Michael P.

Rename init.ora and config.ora also change the db_name parameters. 7. Connect to svrmgrl and run script which you have save as .sql in step 4. Hope this info is helpful for you. Note.

RE: how to rename a database SID
Title: how to rename a database SID See Note Note:15390.1 Subject: How to Determine and Change DB_NAME or ORACLE_SID on MetaLink Here it is below Rick Purpose This entry describes how to find and change the "db_name" for a database, or the ORACLE_SID for an instance, without recreating the database. SCOPE & APPLICATION For DBAs requiring to either find or change the db_name or ORACLE_SID. RELATED DOCUMENTS [NOTE:1018634.102] AFTER RENAMING THE DATABASE SELECT FROM DUAL RETURNS OLD DATABASE NAME [NOTE:9560.1] ALTER TABLESPACE/DATABASE TO RENAME FILES To find the current DB_NAME and ORACLE_SID: === Query the views v$database and v$thread. V$DATABASE gives DB_NAME V$THREAD gives ORACLE_SID If ORACLE_SID = DB_SID and db_name = DBNAME: To find the current value of ORACLE_SID: SVRMGR> select instance from v$thread; INSTANCE DB_SID To find the current value of DB_NAME: SVRMGR> select name from v$database; NAME - DBNAME Modifying a database to run under a new ORACLE_SID: === 1. Shutdown the instance The database must be shutdown with SHUTDOWN NORMAL or SHUTDOWN IMMEDIATE. It must not be shutdown abnormally using SHUTDOWN ABORT. 2. Backup all control, redo, and data files. 3. Go through the .profile, .cshrc, .login, oratab, tnsnames.ora, (for SQL*Net version 2), and redefine the ORACLE_SID environment variable to a new value. For example, search through disks and do a grep ORACLE_SID * 4. Change locations to the "dbs" directory % cd $ORACLE_HOME/dbs and rename the following files: o init.ora (or use pfile to point to the init file.) o control file(s). This is optional if you do not rename any of the controlfiles, and the control_files parameter is used. The "control_files" parameter is set in the "init.ora" file or in a file it references with the ifile parameter. Make sure that the control_file parameter does not point to old file names, if they have been renamed. o "crdb.sql" & "crdb2.sql", This is optional. These are only used at database creation. 5. To rename the database files and redo log files, follow the instructions in [NOTE:9560.1]. 6. Change the ORACLE_SID environment variable to the new value. 7. Check in the "$ORACLE_HOME/dbs" directory to see if the password file has been enabled. If enabled, the file "orapw" will exist and a new password file for the new SID must be created (renaming the old file will not work). If "orapw" does not exist, skip to step 8. To create a new password file, issue the following command as oracle owner: orapwd file=orapw password=?? entries= granted permission to start the database instance> 8. Start up the database and verify that it works. Once this is done, shutdown the database and take a final backup of all control, redo, and data files. The database must be shutdown with SHUTDOWN NORMAL or SHUTDOWN IMMEDIATE. It must not be shutdown abnormally using SHUTDOWN ABORT. 9. When the instance is started, the control file is updated with the current ORACLE_SID. Changing the "db_name" for a Database: == 1. Login to Server Manager % svrmgrl SVRMGR> connect internal 2. Type SVRMGR> alter system switch logfile; to force a checkpoint. 3. Type SVRMGR> alter database backup controlfile to trace resetlogs; This will create a trace file containing the "CREATE CONTROLFILE" command to recreate the controlfile in its current form. 4. Shutdown the database and exit SVRMGR SVRMGR> shutdown SVRMGR> exit The database must be shutdown with SHUTDOWN NORMAL or SHUTDOWN IMMEDIATE. It must not be shutdown abnormally using SHUTDOWN ABORT. 5. Change locations to the directory where the trace files are located. They are usually in the "$ORACLE_HOME/rdbms/log" directory. If "user_dump_dest" is set in the "init.ora" file, then go to the directory listed in the "user_dump_dest" variable. The trace file will have the form "ora_.trc with being a number. 6. Copy the contents of the trace file starting from the line with STARTUP NOMOUNT down to the end of the trace file and put it in a new file called something like "ccf.sql". 7. Edit the "ccf.sql" file FROM: CREATE CONTROLFILE REUSE DATABASE "olddbname" RESETLOGS ... TO: CREATE CONTROLFILE set DATABASE "newd
