Configure Listener

I was bit confused when i first read about listeners but now its very simple for me and here i will explain you how to configure listener and start and stop etc.

Concept :
Listener will simple listen on port specified by you and will accept connections on that port , and finally will connect that connection to started instance of database

client --> LISTENER --> DATABASE INSTANCE (Your started database)

Important Things which you will require while configuring listener

• ORACLE_HOME
• ORACLE_SID
• PORT NUMBER ON WHICH LISTENER WILL LISTEN FOR CLIENT CONNECTIONS

To check your SID on Linux Box :   echo $ORACLE_SID

This SID you will configure in your listener which is currently running instance

Navigate to :

• cd $ORACLE_HOME
• cd  network/admin
• vim listener.ora

Configure listener.ora as follows :

HOST : your ip on which your going to listen

PORT : (Your choice)

ORACLE_HOME , ORACLE_SID check with previous command and enter same here in file.

Thats it!

You simply configured listener names LISTENER (by default name)

How to Start Listener :

$ lsnrctl start LISTENER

How to Check :

$ sqlplus girish/girish@//HOSTNAME:PORT/SID

If everything is proper you should get connected to oracle instance!

WAMP Server: Mysql login Error (Cant open phpmyAdmin)

#1045 - Access denied for user 'root'@'localhost' (using password: NO)

This is very common error encountered while using WAMP server , its because you have not set mySql password and you need to set it first!

Solution :

1) Go to C:\wamp\bin\mysql\mysql5.1.36\bin\
2) mysql.exe -u root -p
3) mysql>
4) Type this query :
     update mysql.user set password=password('1234') where user='root';
5) flush privileges;
6) That's it! now u set password 1234 to mysql.
7) Now whenever you will establish connection with mysql from php pages you will need to provide this password 1234


Thank You,
Have A Nice Day!

Command not found (RHEL 5) chkconfig,service,ifconfig

Hi,

I know its very simple issue but important for beginneers ,
Many times some configuration changes in .bash_profile file may lead to these types of errors . .

As all your commands are there in /sbin/ if $PATH variable is not set properly then you may get this error...

Solution :

1) If you are logged in as root
2) cd ~
3) vim .bash_profile
4) export $PATH=/sbin
5) Thats it.! now you specified your system where to check for system commands!

Fireup your fav system command and check the output!

Oracle Installation Problem : X11 problem

Most probably you will see this line in your error " X11 window server using '192.168.1.2:0.0' as the value of the DISPLAY variable "


This clearly says that problem is related to X11 . . .




Steps :
---------
1) Try executing xeyes as root and check wheather it shows or not . . 
2) now login as your oracle account as ,

    su - oracle


3) Try executing xeyes again if error pops up something like this :


    Xlib: connection to ":0.0" refused by server
    Xlib: No protocol specified

    Error: Can't open display: :0.0

4) Go ahed by firing :  xterm and you will see TERMINAL OPENED 

5) thats it now you can fire xeyes from that terminal 

6) run your oracle installer as  ./runInstaller

Thats It !

can't drop table

drop table xyz;

ORACLE SAYS : exact fetch returns more than requested number of rows ? ? ? how come . . .

yea, once i was playing with dual table and i inserted new row in a dual table which is why i can't drop this table xyz

to Add Rows in Dual table connect to sysdba

1) conn / as sysdba
2) insert into dual values('Z');


Now if you try to drop any table you will get above error to solve it just delete one row from dual table
as

delete from dual where dummy='Z'

Thats it! Now you can drop any table you want without any errors!
Thank You!

Windows XP Commands Not Working

Many Times due to some Environment variable setting in system values of path variable changes . . .which leads to this type of problems.

Ex.

1) If you open command prompt cmd and type any command as 'ipconfig' you get output as :

Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

C:\Documents and Settings\Girish> Ipconfig
'Ipconfig' is not recognized as an internal or external command,
operable program or batch file.

2) Now simple thing you have to do is : change path variable value.

Steps :


1) right click on my computer > properties > Advanced > Environment Variable > System Variable
2) Select PATH variable and click on Edit 
3) Add at the End :   ";C:\WINDOWS\SYSTEM32" without quotes.

That's it now you can fetch any commands in XP you want !

They'll call me freedom
Just like the a waving flag

Boot into Single usermode with Read Write Access to root

Why you want read write access to your system in Single User Mode ? ? Why ? ? Ofcourse its bad practice but we want rw access to bash in some situations like in Maintenance Mode ? ? ? still why ? ? ? ok . . . .lemme explain you . . .

Imagine you are doing LVM (I hope u know LVM) and you already activates USER QUOTA (Hope you know it) Now If this is the situation and you forgot to Disable USER QUOTA before reducing LVM size then probably after restart you will simply lang to maintenance mode!!!

Now what ? ? In this situation you must edit /etc/fstab which is must , to start back your Red Hat!!!! And for this you need to have write access to these files which is not by default!!

Method 1:

When you will boot you will see something like this :

module /vmlinuz-2.6.18-8.el5xen ro root=LABEL=/ rhgb quiet

Here a little modifications can land you to bash prompt with read write access

module /vmlinuz-2.6.18-8.el5xen rw root=LABEL=/ rhgb quiet

Method 2:

You can normally boot in single user mode as :

module /vmlinuz-2.6.18-8.el5xen ro root=LABEL=/ rhgb quiet single

or

module /vmlinuz-2.6.18-8.el5xen ro root=LABEL=/ rhgb quiet 1

you get bash prompt as :

bash# (type here)

bash# mount -o remount /,rw --> which provides read write access to root

Thats how we can get out of maintenance mode . . .

Thank You . . .

My RHCE Experiance

Hi Friends ,

It's not at all a different thing i have done , many of you might have already passed RHCE some of you might have passed RHCSS and blah blah . . .but everyone have their own experience about their certification. So here i will share few things about my experience of being an RHCE.

It was 29th June 2010 , Tuesday

This time Red Hat had a scheme , 11000 for First Shot + 2000 for next shot! Personally don't wann waste money , and no one will rt???So just woke up by 7 and my exam center was Focus Training Institute Pune , which was not close from my place soo was in hurry to reach there on time , Finally reached by 8:15 AM and exam was supposed to be conducted at 9:30 AM , as usual it was not on time because of System Problems.After and hour examiner came there and started formatting pc's , they have some procedure to format each and every machine atleast 5-6 times and then they think they can start exam.So it's very good procedure which i saw there and one thing is that examiner is really a geek and solves any problems that arises in a system quickly, a very talented student of their batch i guess! Don't mind if you are one of them!!!

I was outside the lab and was observing what's going on there on systems and finally figured out that there was Some SELinux service problem and coz of that our exam started late there at center.Ohhhhh! Again we all became restless coz we were just wanted to get rid of exam fast! Finally somehow he was able to solve all of problems in a system . . it was Good as well as bad news for all of us because exam was about to start in few minutes !

Finally he called up names of students one by one , gave one blank paper to everyone , and told me to sit on 3rd machine . Machine was looking scary to me at first site , but as time proceed it was very friendly with me.Finally we started filling a form and signed a NDA (Non Discloser Agreement) So we can't expose questions in exam. Exam started and first 1 and half hour was very gud for me as i could solve all questions except 2 questions related to NIS and SAMBA I thought i can solve it later soo i left those questions and completed my exam paper.But later words i came to know i was in a big trouble!!! Suddenly i saw one BIG SILLY MISTAKE! They were told to create COMMON directory and i created COMMAN directory which was wrong!! Total 3 questions were dependent on this DIRECTORY Ohhhh gOD! Finally had to stop all that 3 services and had to configure NFS,Mount partition and had to set permissions on that again! Now only 20 Minutes left , i thought now its better to reboot system once and did that and what i saw was astonishing once again . . . All my FIREWALL (iptables) rules got deleted coz of my silly mistake of RESTORECON . . . 15 minutes . . . then again was in hurry and applied that firewalls quickly but something was WRONG! 1 rule ! ! ! ohh god...10 minutes . . .started entering commands deleted rule ! ohh my godddddddd but which one? ? it was not one which i want . . correct rule got deleted and wrong remains there only ! 5 minutes . . . again Fast typing and finally each and every entry was correct and then saved it using RESTORECON and rebooted my Server and as soon as login screen came , examiner told me to stop ! ! ! Exam finished!!!

. . . . . .

. . . . . .

. . . . . .

1 and half day was waiting for result and finally i got my Dream Result on 30th June 2010

evening 8:30 Pm

Got a mail from Red Hat Certification Ce.

RHCT components score: 77.8
RHCE components score: 84.4

RHCE Certification: PASS

Thats GreaT!! I was soooooooooooooooooooooooooooooooo happy that day wow! Now i can go for next certification ! This was all about my personal experience of RHCE . . .
