Let's do some shell programming!

1. Check what shell version you have:

export not working in Unix

Problem:

Create a script,  aaa.script

export bbb=/opt/ccc

Then, run it by typing ./aaa.script.

After that, # echo bbb and get nothing.

Solution:

run it by typing . aaa.script

make: 1254-057 Shell command needs a leading tab.

Notice that you need to use tab instead of spaces in line 4,7 and 10. Then, everything goes fine.

Don't use make in AIX, use gmake

gcc and g++ in AIX 6.1

I have these files download from http://www-03.ibm.com/systems/power/software/aix/linux/toolbox/ezinstall.html

They have a certain dependency on each other, so the order to execute them needs to be right.

My order 1->3->4->5->2->6

Then I wrote a simple Hello World app and run it. Get warnings like this, but they don't matter.

rpm -Uvh xxxx.rpm

rpm -Uvh xxxx.rpm

When I tried to recompile a package in sqlplus, the sqlplus window freezes and has not responding.

The reason is that some objects you are trying to use is locked. Go and check what locks the object.

Summary:

TZ=EST5EDT,M3.2.0/2:00:00,M11.1.0/2:00:00

If you change the System TZ, you need to reboot the machine for activating the change.
If you change the date, you don't need to do rebooting.

SP2-1503: Unable to initialize Oracle call interface

Problem:

Install everything correctly, but can't use sqlplus from both double-click and command line.

Solution:

Run as adminstrator

Set AIX date and time

# date 0819092612
           mmddHHMMyy

all see the man page

mm-month
MM-minutes
yy-last two digits of year

Vim setting

set tabstop=4
set shiftwidth=4
set number
set backupdir=c:\vim_backup

vi/vim tips

1.Copy and paste

In normal model:

10yy     --Copy next 10 lines
p           --Paste the content


2. Tab multiple lines

v           -- Go into Visual Mode
shift + direction(h,j,k,l or arrows)    -- select lines
> or <      -- indent or unindent

Display the output of oracle procedure

I wrote a simple sample like:

DECLARE
    hello varchar(10);
BEGIN
    dbms_output.put_line('Hello World');

END;
/

When I run it on sqlplus, it showed: PL/SQL procedure successfully completed. Nothing else.

The solution is:

sqlplus> set serveroutput on

Then you can see the output.

Thread: ORA-01552: cannot use system rollback segment for non-system tablespace

The undo_ xxx is set to manual in my pfile and init-ora. So I changed it to AUTO.

ORA-30012: undo tablespace ‘UNDOTBS01′ does not exist or of wrong type

I modified the undo_tablespace in init-ora file and spfile by changing undotbs01 to undotbs02 and it worked.

OUI-18001: The operating system 'AIX Version 6100.05' is not supported.

I am installing ORACLE 10.2.0.2 today on an AIX 6.1 machine. This error poped up when the software is checking the prerequisites of the system. Since AIX 6.1 comes after ORACLE 10.2.0.2, so just ignore the error and keep installing.

Refer to

http://www.dba-oracle.com/oracle_tips_db_copy.htm 

and

http://dbaforums.org/oracle/index.php?showtopic=2917

if you want to clone a database TEST -> DENEME 
1 take a backup of your controlfile 
2 take online / offline backup of all your datafiles 
3 make a relevant copy of your init.ora file or make changes to you are deneme initora
4 delete your control file, redo logs and datafiles on DENEME
5 move these files from TEST -> DENEME
6 using the back up of control file create the new control file for deneme 
NOTE the database name needs to be changed from TEST -> DENEME with the 
SET Clause and option resetlogs (depending on hot /cold backup)
7 create the redo log files
