Behind the scenes 2. - the 12.2 online patching

Not advertised "features" of the online patching function

One of the most advertised new feature of the 12.2 system is the new online patching function. The Oracle's marketing was that this new feature will help to cut down the scheduled maintenance outages of an EBS system.

But what are the not publicated, not advertised "(dis)advantages" of this feature?

1. new patch tool
2. doubled/tripled file system
3. new "patch top" directory
4. new patching lifecycle
5. new restrictions
6. new multi node patch procedure
7. online patching db tools
8. FNDLOAD and Online Patching
9. Cloning and Online patching
10. Directory Structure and Online Patching

Cloning a 12.2 EBS with rapid clone

Cloning 12.2 EBS 

The 12.2 EBS cloning has been dramatically changed in the 12.2 version. The main concept still the same, (preclone, copy files, post clone), but the underlying logic was changed.

First you will not find Rapid Clone note for 12.2 on Oracle's Support site (The following document mention the 1383621.1 note, but is just a "rapid clone bug list" now, not a complete step by step note as the earlier notes were). You should open the "Oracle® E-Business Suite Setup Guide Release 12.2" document and read chapter 17 "Cloning Oracle E-Business Suite with Rapid Clone".
