st put in "cd 18522512 opatch apply"？Should I "startup" and "@catbundle.sql psu apply"? We are applying patch only at binary level in 3rd step, i.e. opatch apply Database start up and catbundle execution is covered in step 7 We can do this step along with opatch apply, but for applying overlay patch (step 4) again we have to shutdown the database. To avoid that we apply all patches at binary first, then start the database to execute catbundle.sql
11.2.0.3.11的PSU是包含11.2.0.3.7的PSU的。Apply 11.2.0.3.11的PSU，是会先APPLY 11.2.0.3.7版本的。但是，已经存在的patch 13004894跟这个11.2.0.3.7 PSU有冲突，因此我们需要安装13004894的11.2.0.3.7版本，这个PSU，是会包含11.2.0.3.7的PSU与13004894这个patch的协调版本。

We would like inform you about new MOS feature.
A new Patch Conflict Checker feature is available in the latest release of MOS. This is accessible from the Patch Search results screen ("Analyze with OPatch" button) and allows you to analyze candidate patches for conflicts and request merge fixes a lot more easily and quickly at the time of patch download itself. This feature allows you to:
1. Analyze patches for conflicts right at the time of patch download - All you need is your Opatch inventory.
2. Locate already available replacement patches ? So, you can download resolution patches immediately.
3. Request a merge patch right there, if no replacement patches exist - You will not have to spend time logging a SR.
For more information and a demonstration video, please see Note 1091294.1 - How to use the My
Oracle Support Conflict Checker Tool. Should you need assistance get started, I am glad to set up a call/web conference to walk you through the steps.
