Issues between RMAN Client and Database

Some Issues between RMAN Client and Database:---------------------------------------------------•Most RMAN commands take a number of parameters and must end with a semicolon.The exception is some database related command , like STARTUP, SHUTDOWN and CONNECT.•You can write rman commands in a file and then you can run the file. In both ways from command line and within RMAN command prompt you can check.$rman TARGET / @filenameRMAN>@filenameAfter the command file contents have been executed, RMAN displays the following message:RMAN> **end-of-file**•With CHECKSYNTAX you can test some RMAN commands for syntactic correctness without executing them.In both ways from command line and within RMAN command prompt you can check.$rman CHECKSYNTAXRMAN>run your command.From Command Line,rman CHECKSYNTAX @filenameExample:-------------1)Make rmancmdtest file with following entry-bash-3.00$ cat rmancmdtestlist backup;show all;2)From RMAN command prompt checking the syntaxRMAN> @/export/home/oracle/rmancmdtestRMAN> list backup;The cmdfile has no syntax errorsRMAN> show all;The cmdfile has no syntax errorsRMAN> **end-of-file**3)Now from OS Command line-bash-3.00$ rman checksyntax @/export/home/oracle/rmancmdtestRecovery Manager: Release 10.2.0.1.0 - Production on Thu Apr 24 10:16:07 2008Copyright (c) 1982, 2005, Oracle.

In the following section I have given an example.1)Here I used System/a but it actually connected to database with SYSDBA privilege automatically, OS Authentication is used.bash-3.00$ rman target system/aRecovery Manager: Release 10.2.0.1.0 - Production on Thu Apr 24 09:23:35 2008Copyright (c) 1982, 2005, Oracle. All rights reserved.connected to target database: DATA1 (DBID=2547250380)2)After connecting I created a Table and Insert one row.RMAN> sql'create table test (a number)';using target database control file instead of recovery catalogsql statement: create table test (a number)RMAN> sql'insert into test values(100)';using target database control file instead of recovery catalogsql statement: insert into test values(100)3)Now connect with system and see the object. Because SYSDBA privilege conenction use SYS schema so in SYSTEM there is no object. Here system/a is nothing but a show. Any user or any password would work if current user is a member of OSDBA group.-bash-3.00$ sqlplus system/aSQL*Plus: Release 10.2.0.1.0 - Production on Thu Apr 24 09:23:10 2008Copyright (c) 1982, 2005, Oracle. All rights reserved.SQL> desc test;ERROR:ORA-04043: object test does not exist4)Now Check object in SYS schemaSQL> conn / as sysdbaConnected.SQL> desc test;Name Null? Type----------------------------------------- -------- ----------------------------A NUMBERSQL> select * from test;A----------100Caution: As to run any SQL command it is needed to connect to target database and to connect target database you must have SYSDBA privilege and SYSDBA privilege use SYS schema so it is not good practice to create object from RMAN client.Though you can create obejct in other schema from RMAN using,RMAN> sql'create table system.test(a number)';using target database control file instead of recovery catalogsql statement: create table system.test(a number)

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
