Hi Atul
While Patching, As Per documents
1. We have to set the environment variables
2. We should enable Maintenance Mode
3. Stop Services (current Mgr, Forms Server, web server)
4. Apply Patches thru ad Patch (As per Read me file) & review the log files
5. Disable Maintenance Mode (adadmin)
My seniors skipped 1 & 3.
Please explain why he had skip the above 1 & 3 steps
Thanks & Regards
KK

 

Hi KK,

Hi Atul,

Apart from this reply. I have question for you.

As you discussed about d driver. The way we apply u driver on RAC node with nodatabaseportion. Can we use same option while applying d driver on RAC node.

Waiting for your response on this.

Bob

 

KK,
Apologies as I missed replying to your previous comment.


Bob,
I hope you on RAC node , from one database node you are running patch as normal & from second RAC Node you are using nodatabaseportion. Yes for d driver you can use same .

KK, Maintenance mode was introduced in AD.I, so if your AD Version is less than I then there was no option to put Apps in Maintenance mode & you could apply patch while Instance was Up
or
as Bob mentioned ur senior might be using options=hotpatch

Atul

 

Thanks Atul.
I have the following questions regarding patch application:
1- How can we know what our patch level is?
2- When can we know we need to apply one patch (only when users complaints about a bug?
When there are performance problems? To be on the latest patch level? Why should we apply a patch?)
3- It is not very clear for me:
You said: d driver you just need to apply once on concurrent manager tier why not database tier?
Can I understand: d on database tier, c &g on all application tiers and on database tier (one time)?

How to deinstall the patch 4028184

 

Shivu,
Since this is Apps patch applied using adpatch (This is minipack) so you can not uninstall this patch . Only option is to revert back to backup before applying this patch

thanks but i know what are ldt and lct files. my question is what the ldt files inside a patch_top used for. i m not asking abt the ldt or lct files supplied with a patch to be applied to the instance. i m talking abt the 2 ldt files which are present in a patch_top for all the patches irrespective of the patch type. i wanted to know what are these ldt files and why are they used or how are they used by adpatch?u can try unzipping a patch and find out by urselves.

 

how to apply a patch on a shared APPL_TOP. How to know which is the primary noe.

 

Apply from any node which plays roles of admin server

 

Hi Atul,

Than q for the information.
But still I've a doubt. You mentioned that d.drv updates the database.
Does this mean that it updates the RDBMS_ORACLE_HOME or anything else?

Than q.
