When To Apply Bundles and MPs.

When To Apply Bundles and MPs.


Normally bundles are collection of fixes and one or more bundles constitutes a MP
MPs normally are two types. Cumulative and Delta

When to apply cumulative MP:

If you have not applied any patches, bundles or MPs (delta or cumulative). Cumulative MP is the quickest way to make a vanilla database current.
After applying a cumulative MP, subsequent Delta MP or bundle can be applied.

When to apply delta MP:

After you have applied a cumulative or delta MP and have not applied any patch or bundle after that. After that you can apply next delta MP or next bundle. Once you apply a bundle you can no longer apply MPs. You need to keep applying subsequent bundles.

When to Apply a bundle:

You have applied a bundle or MP previously.
You are on MP and cannot wait for the next delta MP
After a bundle is applied you need to keep applying next bundles, you cannot apply a MP on top of a bundle.This means if at any time you apply a bundle in your DB you cannot apply MPs further. You need to proceed with bundles when they get released.
