Hi,

Actually i have attended to check the linux server

hardware dell(x86)

REDHAT linux 5.3 version 2.6-128.e5 64bit for big company that they had more than 6 server had installed linux redhad 5.3 and they had installed application server(oracle).and they said these application server is not working well,how can i know this issue from linux or from their application and how to check that?

thanks.

There could be so many problems that nobody will be able to tell you where to start, unless you tell what the problems or symptoms are.

But maybe it is wiser to ask someone with more expertise to do this. Forgive me if I am wrong, but you don't really sound as if you know what you are doing. Your company probably cannot accept lots of downtime when things go wrong.

give some more detail of error and if possible try to install again RED HAT and then your application....

Your post is difficult to understand exactly; in the interests of making good progress when you (eventually?) contact Red Hat, please try to be clear about at least the following:

Attended? Do you mean that you are currently waiting to test the server, or was 'attempted' what you meant to write? If it was 'attempted', what did you try, what did it show?

So, they certainly will be paying Red Hat for support. This is good as you are about to need the support for which you are paying,

Are all of those 6 servers the same, and only one has the problem? Or, do all six have the problem? Or something else?

You mention the Oracle Application server. This is a Red hat server, upon which you have installed an Oracle application (Oracle database itself, or something else from Oracle?) and not a separate Oracle Unbreakable (a trademark, not a literal description, necessarily) installation, isn't it?

When you say 'not working well', what does that mean? What is the evidence of that (provide the output from some monitoring utility that demonstrates what 'not working well' might involve, which may or may not be different from what you are currently describing as 'not working well'. What is it that convinces you that 'not working well' is some kind of fault rather than a natural result of using this level of resources, whatever that is, for this level of workload, whatever that is.

So, you have dismissed the possibility of any kind of interaction between Linux and the application. That simplifies things (but may be wrong).

You really need to be monitoring things, and the obvious place to start is the 'top' family of utilities. Unfortunately, you have probably left this a little late to start, in that the output will probably be a little difficult to disentangle if you have no experience of the software that you are using.

You also need to be more specific than:

as that doesn't say anything about the processor, the RAM or the storage arrangements, all of which could be critical in determining what workload the server should be capable of...and, of course, we don't know anything about the workload, so commenting on whether the server is behaving as would be expected for the workload would be impossible, with this level of information.

Hi all,
Thanks for take care of my processes,all they were correct i didn't give you more information so this some of

Dear mr.salasi

you asked about how many servers,they are 6 server ,3 for production and 3 for test and one of these server (only one) has problem that which application server installed on it,other server working well nothing is there and also the samba server and Dns server not installed.Further more
there is no fail over or cluster software was installed,the oracle dba told me about one server which installed the application server was installed not working like other server even that on test and he stopped that application till he know about the issue,is that from os or from application.now whate he told me that should i tell him about this issue.one more thing these servers are connected together.if you know about the hardware this dell (powerEdge M610)intell xeon x555 2,67mhz(2 physical processor)and this connect to san storage.i have checked all and it's look like fine ,but i have to be quite sure about that.i hope this be more than enough for you and i need more tell me and i will checke that.

You still have not given any information that would be useful in assisting to determine what the issue might be. What do you mean by "not working well"? What is the "application server"?

Presuming that all of this is licensed software (Red Hat, Oracle, etc.) you should have support available from the software vendor. Your best bet for getting an absolute resolution is calling them and working with them. After all you are paying for the support, and if you aren't you shouldn't be using the software. Also since they will be able to coordinate with you to review logs, and do various tests that we can not.

If you do insist on using this forum support you will need to provide much better detail in terms of explaining what the problem(s) are. If the problem is that you (or the developer) feel that the server in question is slow then provide hard evidence. How long does it take for an action to be done on a server that works well? How long does it take to perform the same action on the "bad" server? Is there anything in logs? Any indicator lights on the server itself?

Hi all,

I have two servers (powerEdge M610)intell xeon x555 2,67mhz(2 physical processor) and i have installed REDHAT LINUX VERSION 5.4 and i configured REDHAT cluster software.Both are connected to san storage and oracle database has been configured on this cluster.also
we have two ups once one crashdown the second will bo online(fail over).

The problem is, when the issues happen on the central ups,both nodes are going down.they
shouldn't be like that!if one going down the other node should be online because both on
cluster and failover there,but after both going down then i should reboot the san storage and then i have to reboot both node,now any thing is going on and i have checked the /var/log/message directory on the first node and i found service down is called multipath,is it effect or not?becouse only one switch that connect those nodes with san storage.may be we need two switches to handle this problem in the future,so please some one guide me on this
