STEPS: STEP 1: Check the size of the mount points using df -h STEP 2: Moving the datafiles without bringing down the database, Issue the following command, ALTER DATABASE MOVE DATAFILE ‘/prdadata01/oracle/PRODA/db/apps_st/sample/sample.dbf’ TO ‘/prdadata01/oracle/PRODA/db/apps_st/data/sample.dbf’; STEP 3: Moving the redo logs from one mount point to another mount point, Bring down the application node, sh $ADMIN_SCRIPTS_HOME/adstpall.sh apps/<appspassword> Bring down the listener and database lsnrctl stop shut immediate STEP 4: Issue the following OS command mv /prdadata02/oracle/PRODA/db/apps_st/data/log01a.dbf to /prdadata01/oracle/PRODA/db/apps_st/data/log01a.dbf mv /prdadata02/oracle/PRODA/db/apps_st/data/log01b.dbf to /prdadata01/oracle/PRODA/db/apps_st/data/log01b.dbf mv /prdadata03/oracle/PRODA/db/apps_st/data/log02b.dbf to /prdadata01/oracle/PRODA/db/apps_st/data/log02b.dbf mv /prdadata03/oracle/PRODA/db/apps_st/data/log02a.dbf to /prdadata01/oracle/PRODA/db/apps_st/data/log02a.dbf…

Read MoreEXPORT DP AND IMPORT DP IN SCHEMAS PARAMETER USING PARFILE In this tutorial we are going to learn about how to do export and import datapump using schemas parameter DESCRIPTION: A schema export is specified using the schemas parameter. This is the default export mode. If you have the DATAPUMP_EXP_FULL_DATABASE role, then you can specify a list of schemas, optionally including the schema definitions themselves and also system privilege grants to those schemas. If you do not have the DATAPUMP_EXP_FULL_DATABASE role, then you can export only your own schema. The sys schema cannot be used as a source schema for export jobs.

Read MoreORACLE DATABSE CLONING USING COLD BACKUP DESCRIPTION: The Cold database backup is, while taking backup or doing cloning, we need to shutdown the source database. This method is usually used for test server when database is in no archive log mode. First we want to take a backup of control file, note down the data file location, and finally shut down the database in source database side. Second. Transfer the data file, temp file to target database, create a pfile(init.ora) for target database. Then start the target database in no mount stage, then in there recreate a control file, then open the database in reset logs. Send the datafile,log files and control files to target destination: [oracle@oracle trainee]$ scp -r *.log oracle@192.168.1.122:/u01/shan The authenticity of host ‘192.168.1.122 (192.168.1.122)’ can’t be established.
