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. All rights reserved.RMAN> list backup;2> show all;3>The cmdfile has no syntax errors Access database with SQL command from RMAN:-----------------------------------------------------You can write sql commands with RMAN to access database. 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)

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...

ORA-00939: too many arguments -when case arguments exceed 255

Problem Description In all Oracle 10.1g and oracle 10.2.0.1, 10.2.0.2, 10.2.0.3 whenever there is more than 255 arguments inside CASE statements then following error is returned. ORA-00939: too many arguments for function But surprisingly on Oracle 9.2 database the same code does not return any error. Cause of the Problem As we see the same code return error in 10g but it is well on 9.2. In fact this is problem of oracle 9.2 that it does not return any error. It should return error if there is more than 255 arguments inside CASE statements. In oracle 9.2 this is bug number 2909927 and this bug is fixed in oracle 10.1 and 10.2. That's why in 10.2 and 10.1 error returns if arguments exceed 255. Up to Oracle 10.2.0.3 and earlier version, the arguments of CASE statement is limit to 255 and it does not support exceed over 255 and hence error return if it exceed. However in Oracle 10.2.0.4 and later the arguments limit of CASE statement has increased to 32767. Solution of the Problem Opt...

ORA-31655: no data or metadata objects selected for job

Problem Description You are going to do data pump export operation in order to export objects based on filtering via EXCLUDE or INCLUDE parameter of expdp. In this example you wanted tables 'ACCOUNT_GROUP','ADDRESS','AREA_GROUP' and all the tables starting with word CV(like 'CV', 'CV_EXPERIENCE', 'CV_EDUCATION' etc) Your parameter file is like below. userid=smilebd/a directory=d dumpfile=b.dmp include =TABLE:"IN('ACCOUNT_GROUP','ADDRESS','AREA_GROUP')" include =TABLE:"LIKE 'CV%' " And you invoke expdp as expdp parfile=d:\parfile.txt from command line. But it fails with below message on my windows PC. C:\>expdp parfile=d:\parfile.txt Export: Release 10.1.0.4.2 - Production on Thursday, 29 January, 2009 14:53 Copyright (c) 2003, Oracle.
