How to resolve "Self extraction to C:\Users\temp\AppData\Local\Temp\orcl942564381009262456.tmp failed error while installing ODI 12c

While trying to install ODI 12c, When tried invoking the jar file in CMD then got an error
"Self extraction to C:\Users\temp\AppData\Local\Temp\orcl942564381009262456.tmp failed.

For some reason the 2nd file was not detected. So Solution is to keep both disk file installable in same one folder.

Which will resolve the issue.

Difference between OSB 11g And OSB 12c

Following below are the difference between OSB 11g and 12c:-

(I) In the new version Oracle Service Bus (OSB) is renamed as Service Bus.
(ii) Eclipse tool is needed to develop an interface in OSB 11g where as JDeveloper tool is needed to develop an interface in OSB 12c. 
(iii) Re-sequencing in OSB, In 11g this feature was available in Mediator, in Oracle SOA 12c this features added to service bus also, with the help of this feature we able to process the request message in proper sequence.
(iv) Pipeline is separated from proxy service and it is separate component in 12c.
(v) MDS support is provided for OSB.
(vi) Because a SB project is more like a SCA Composite (same overview) the Proxy is split from the Pipeline. This means that the Proxy and the Pipeline are two individual things. With this concept multiple Proxies can be wired to one Pipeline. Say you have a "Any XML" Pipeline, you can process the data from both Proxies (i.g. File adapter and JMS Queue).
(vii) One of SOA Suite 12c pillar is Mobile Enablement. You can expose a Pipeline as a REST service. When doing it creates a REST binding just like in a SCA Composite. In the wizard you can assign specific Resource Paths and Operation for the operations of the Pipeline. Downside is that you can only expose Pipelines that have a WSDL interface.
(viii) SB also supports the use of templates. But it works a little different. Templates are Pipeline-based, this means that you can select a template when creating a new Pipeline. There are two types of templates; Unlinked, which is a copy of the template, and Linked, Pipeline stays connected to template. In the template you can use Placeholders so permit changes to that part of the Pipeline. If the Pipeline is linked to a template and the template is changed the linked Pipeline will inherent these changes.

Oracle WebLogic Server on Docker

What is Docker:-

Docker is a virtualization technology that uses containers.  A container is a feature that was added to the Linux kernel recently.  Solaris has had containers (or ‘zones’) for a long time.
Unlike a VM, it does not emulate a processor and run its own copy of the operating system, with its own memory, and virtual devices.  Instead, it shares the host operating system, but has its own file system, and uses a layering technology to overlay sparse file systems on top of each other to create its file system.
When you are ‘in’ the container, it looks like you are on a real machine, just like when you are ‘in’ a VM.  The difference is that the container approach uses a lot less system resources than the VM approach, since it is not running another copy of the operating system.This means that more of your physical memory is available to run the actual application you care about, and less of it is consumed by the virtualization software and the virtualized operating system.

You can use Linux containers without using Docker.  Docker just makes the whole experience a lot more pleasant.  Docker allows you to create a container from an ‘image’, and to save the changes that you make, or to throw them away when you are done with the container.

These images are versioned, and they are layered on top of other images.  So they are reusable.  For example, if you had five demo/training environments you wanted to use, but they all have SOA Suite, WebLogic, JDK, etc., in them – you can put SOA Suite into one image, and then create five more images for each of the five demo/training environments – each of these as a layer on top of the SOA image.  Now if you had one of those five ‘installed’ on your machine and you wanted to fire up one of the others, Docker allows you to just pull down that relatively small demo image and run it right on top of the relatively large SOA image you already have.

If you customize the demo and want to share the customizations with others, you can ‘push’ your image back to a shared registry (repository) of images.  Docker is just going to push the (relatively very small) changes you made, and other people can then use them by running that image on top of the ones they already have.

Running your customized image on top of the others they have will not change the others, so they can still use them any time they need them.  And this is done without the need for the relatively large ‘snapshots’ that you would create in a VM to achieve the same kind of flexibility.
