Pre-Installation RAC environement setup check with CVU

Checking the Network Setup with CVU
To verify node connectivity among all nodes in your cluster use following syntax as an oracle user,
/mount_point/crs/Disk1/cluvfy/runcluvfy.sh comp nodecon -n node_list [-verbose]

If you have two nodes node1 and node2 and your mountpoint is /dev/cdrom then enter following command.
/dev/cdrom/crs/Disk1/cluvfy/runcluvfy.sh comp nodecon -n node1,node2 -verbose

Checking the Hardware and Operating System Setup with CV
As an oracle user use the following command syntax to start Cluster Verification Utility (CVU) stage verification to check hardware and OS setup:

/mountpoint/crs/Disk1/cluvfy/runcluvfy.sh stage –post hwos –n node_list [-verbose]
If you have two nodes node1 and node2 and your mountpoint is /dev/cdrom then enter following command,
/dev/cdrom/crs/Disk1/cluvfy/runcluvfy.sh stage –post hwos –n node1,node2

Checking the Operating System Requirements Setup with CVU
To check if your system meets the operating system requirement pre-installation tasks use the following syntax,
/mountpoint/crs/Disk1/cluvfy/runcluvfy.sh comp sys -n node_list -p {crs|database}
-osdba osdba_group -orainv orainv_group -verbose

If you have two nodes node1 and node2 and your mountpoint is /dev/cdrom with the OSDBA dba and Oracle inventory group oinstall then enter following command,
/dev/cdrom/crs/Disk1/cluvfy/runcluvfy.sh comp sys -n node1,node2 -p crs -osdba crs -orainv oinstall

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.
