Hi Atul,

Nice post.
Just a minor correction.Instead of
Apply 12.0.2 patch 5484000 using adadmin

it should be

Apply 12.0.2 patch 5484000 using adpatch.

Hi Atul,

would you consider publish any DST patch tips on OAS. I installed OAS and then upgrade to 10.1.4 on Window XP as my development OAS/portal. It was working fine until 3/11/08 DST kicks in. The metalink doc regarding DST patch requires a seasoned DBA and I am just a Portlet developer who knows some OAS installation/configuration.
