The LIST, REPORT, and DELETE Commands in RMAN

List Command:------------------The LIST command uses RMAN repository information and provide lists of backups, archived logs, and database incarnations.Output of LIST command can be filtered BY BACKUP and BY FILE option.1)RMAN> list backup; #List all your backup sets.2)RMAN>LIST BACKUPSET; #Lists only backup sets and proxy copies.3)RMAN>LIST COPY; #Lists of Image copies and Archive Logs.4)RMAN>LIST EXPIRED BACKUP; #Backups did not found after crosscheck. That is backup is manually moved or deleted from OS.5)RMAN>LIST BACKUP BY FILE; #List backup by Datafile, controlfile, spfile.6)RMAN>LIST BACKUP SUMMARY; #Lists backup sets, proxy copies, and disk copies.7)LIST BACKUP OF DATABASE; LIST BACKUP LIKE '/tmp/%'; list backup of datafile 1; LIST ARCHIVELOG ALL BACKED UP 2 TIMES TO DEVICE TYPE sbt;LIST COPY OF DATAFILE 2 COMPLETED BETWEEN '17-MAR-2008' AND '22-MAR-2008'; are also available.8) LIST INCARNATION; LIST INCARNATION OF DATABASE; to see the incarnations of your database.Report Command:-------------------RMAN REPORT command analyzes the available backups and return results about while files need backup which files are obsolete etc. Remember the result of REPORT command is based on repository data. So, if backups have been deleted from disk or tape outside of RMAN, reports generated by RMAN do not automatically reflect these changes.So before report it is good to run CROSSCHECK of all backup in order to update repository.1)REPORT NEED BACKUP; # Determine which database files need backup under a specific retention policy.2)REPORT UNRECOVERABLE; #Report which database files require backup because they have been affected by some NOLOGGING operation.3)REPORT SCHEMA; #Lists and displays information about the database files.4)REPORT OBSOLETE; #REPORT OBSOLETE displays the backups that are obsolete according to the current retention policy.5)REPORT NEED BACKUP RECOVERY WINDOW OF 2 DAYS DATABASE SKIP TABLESPACE data01;If you use Recovery Catalog then past data can be shown.Like, REPORT SCHEMA AT TIME 'SYSDATE-10';Delete Command:--------------------Delete commands is used to delete any backup or backupsets.1)Delete all your backup sets RMAN> delete backupset all;2)Delete all image copies. RMAN> delete copy all;3)Delete obsolete Backups. RMAN>DELETE OBSOLETE;

How to make partitioning in Oracle more Quickly

As the table size grows and full table scans happens more frequently then there is no alternative than partitioning in oracle. Partition greatly enhance performance of a query. I will start my partitioning system simply with an example. In my database the following query took 30~35 seconds to complete. After partitioning the performance increased amazingly and it then took only 1 second. My query was, SELECT DISTINCT fs.type, fs.id , fs.pid, fs.cid , fs.cr_id, fs.created_date FROM summary fs where fs.id in (select fa.id from forms fa where fa.sar in (select la.sar from login la where la.login_id=1 and fa.created_date BETWEEN to_date('1-MAY-2008') AND to_date('21-SEP-2008') and fs.created_date BETWEEN to_date('1-MAY-2008') AND to_date('21-SEP-2008') ) )and mode=0; After seeing above query I decide to make range partition on column created_date both in summary table and forms table. Below is the list of procedur

Copy files between Unix and Windows with rcp

There are many third party tools by which you can copy files between windows and unix machine. Some common tools are winscp, SSHSecureShellClient etc. Instead of using any third party tool, you can use original unix and windows built-in tool to do the task. The RCP (Remote CoPy) is a standard UNIX tool and a Microsoft Windows 2000 tool that copies files/folder to and from computer running the RCP service. Before you can use the RCP tool from a Windows-based computer you must do something in your UNIX computer. you must turn on the RCP service and update the security files to allow the Windows-based computer to connect to your unix machine over this service. The following steps will help you. Step 01: Turn on RCP service on UNIX Host Turn on the RCP service on unix machine by using inetd: 1. Log on as root. 2. Edit the file /etc/Inetd.conf. 3. Uncomment the lines that start with shell and that start with exec. 4. Save the file. 5. Use ps -ef |grep inetd and determine inetd service p

ORA-04062: timestamp of procedure has been changed

Problem Description In the database I have created one procedure named a as below. create or replace procedure a(a number) as begin insert into t1 values(1); commit; end; / Now after creating database link using remote database machine whenever I access this procedure "A" it executes successfully and I get value "1" in table t1. Like below in example where orastdby_m is the database link, shaik is the schema name and value 1 is the argument value though argument value is not used in the procedure. SQL> exec shaik.a@orastdby_m(1); PL/SQL procedure successfully completed. Now in the source database machine I changed the procedure as below. Though you can change anything like any literal; adding space or remove space. I changed value to be inserted from 1 to 2. create or replace procedure a(a number) as begin insert into t1 values(2); commit; end; / Now in the other database whenever I execute the procedure using database link it throws error ORA-04062. But subseq
