175485.1 How to apply an 11i patch when adpatch is already running
If you are applying a big patch which need hours and get into a problem which needs to apply another patch to fix the problem, you need above metalink internal note to apply this patch. As it is an internal note, you cannot download it from mysupport. Following is from beginapps.blogspot.com. check oracle-magic.blogspot.com for similar note.
However, if the patch is small, you can apply another patch by not continuing the previous adpatch run. After the patch fix, apply the previous patch again.
