Hi everyone,

My Personal Machine (LAPTOP)

The Problem is, OUI gives warning to change kernal values.
Current kernal values are for 11g database.

In this case, to install 10g database,
Can i change kernal values ?
I am in confusion.

What are you confused about? Either the values are greater than or equal to what you need. If they're less, then increase them. Simple. Oracle has all of the kernel values and other installation pre-requisites clearly spelled out in their installation documentation.

And since you're using Oracle, you're paying for it right???? Have you contacted Oracle support with your questions?

::edit::
You said here: http://www.linuxquestions.org/questi...0/#post5719061
...and as an Oracle DBA, you don't know how to install/configure Oracle?

Hi TBone,

I presume you are NOT getting my questions.
I installed 11g very long back that time i set kernel values.
So those values are specific to 11g Sw.

>> To install 10g sw ,

IF i change kernel values, will it affect 11g databases ?

Understand them just fine...but it seems like...
...you are not understanding the answers. Again, you're an Oracle DBA, so it's odd that you don't know these things. Again, if the values are LESS than what its calling for, then INCREASE them. That's a yes/no question...are the values you have set *NOW* LESS THAN what the 10 instructions are calling for??? If they're not...then you VERY OBVIOUSLY have the parameters for the kernel set high enough to work.

Again, since you're an 'Oracle DBA', setting the values LOWER than they need to be will affect performance/operation.

I am just using SW only for learning purpose.

Thanks.

It DOES NOT MATTER what you're using them for...OEL, Oracle and RHEL are commercial, PAY FOR things. Using them past the trial date isn't a good thing. Either pay for what you're using, or use CentOS and MySQL instead.

Hi TBOne,

You are misleading - Please do NOT mind.
Oracle allows everyone to download sw.
You can see globally Oracle professionals are downloading OEL and 12c.

They are free (NON commercial purpose).

I am an Oracle professional, why i need MY-SQL and Cent OS.

Not misleading at all...very plain and simple. And you are incorrect. Yes, anyone can download Red Hat enterprise, OEL, and the Oracle database engine. Mind telling me on the Oracle website where you see the "Free for non commercial use"??
http://www.oracle.com/us/corporate/p...sts/index.html

There are development copies, but they are bundled under the PURCHASED license. The ONLY Oracle database which is remotely free is the Express edition, which lacks many features (Oracle XE). But you're not using that, based on what you posted. As an 'Oracle Professional', you are aware of the differences between 10, 11, 12, and XE, right?
Because you're not paying for RHEL or Oracle. Neither free, which you seem to be missing. And if you're an 'Oracle Professional'...why don't you know how to install Oracle, or what modifying the kernel parameters may do to a database? These seem like things an 'Oracle Professional' would know.

I can install Oracle 10g/11g/12c - no confusions.


usually we do --> first 10g, 11g then 12c - Here no problem.
Suppose we do reverse process, (first 11g then 10g) - small confusions are common.

Thanks for your kind response

..except you're not paying for any of them.
You said you're a DBA/'Oracle Professional'; what is there to be confused about??? Again, you are not understanding the answer, and I don't know how to make it more simple.

To give you an example: If Oracle 10g says "Set <kernel parameter> to 12000", and it's already set to be 13000 in 11g....13000 is MORE THAN 12000 isn't it???? So if the minimum/pre-requisite is 12000, you're set. If it's NOT then set it higher. Do you not understand that??? If it needs to be lower, then obviously 11g is going to have a problem. But an an 'Oracle Professional' you should be able to deal with it.
