India Localization Patching 11i

Question

Hi,
Recently we got a request for applying India Localization Patch 8266575 and have a few questions:
Question 1:*
When we go into the Readme of the Patch it talks about having patch 6491231 (India Localization Patch Application Tool) and apply the requested patch 8266575 with only with this tool.
Extract From Readme:
If you have applied the patch 6491231 from metalink (India Localization Patch Application Tool), you should be able to apply this patch using that tool.
My question is how do we check the current India Localization Patch Application Tool version (i.e. patch version).
Question 2:*
Also the section "File Application Version" portion same readme talks of a script. Do we need to run the script once the patch is applied.
Extract From Readme:
File Application instructions
*=============================*
*## For the sql files listed below (if any), apply in respective schemas as given.*
- sqlplus APPS/<apps_pwd> @patch/115/sql/ja_in_po_hdr_vendor_upd_trg.sql
Question 3:*
Also please let me know if need to down the application tier services when applying "India Localization Patch"
Please help us me out.

Hi Hussein,
Thanks for the update.
With regards to the version that I was talking about what I want to know if I need to apply the patch 6491231 (PATCH TOOL) or not.
Fotr this I would like to know if the patch 6491231 is applied or if a higher version of the patch tool exists or if the patch tool is lower than the version provided in the patch 6491231.
The version checking portion of the patch 8266575 gives version of the file that the patch is going to update.
-bash-3.00$ sqlplus apps/<PASSWORD> @jai_8266575.sql

I believe that the script *"@patch/115/sql/ja_in_po_hdr_vendor_upd_trg.sql"* takes a backup of the files being changed by the patch.
As such I am presuming that the script needs to run prior to the patch. Could you please confirm if I am correct.
Also the user manual does not talk about bringing down the any services or not bringing down the services. As such please advice.
This is the first time I am applying this type of patch as such the questions & confusion.
Would appreciate any further inputs into the matter.
