Previous blog The Full Monty – Part 9 – The CE2 Install

it’s all well and good, getting a system on you machine when it goes in well, but what about when it goes belly up, or you just want to remove the installation from your machine.

This blog steps through the simple process of removing a CE2 installation which takes around 40 minutes.

Currently I have the CE2 and NSP on my VM.

Upon boot up of the machine, the MMC shows no systems started

image

and my SAP specific Windows Services stand as

image

and

image 

Poking around, I found the uninstall.exe program in “C:usrsapCE2SYSexeucNTI386”

image

I double clicked to execute

At the first screen, there was nothing I could do. The SAPSID is disabled.

image

 

I selected “Next”, and off it went to perform certain checks

At the next screen, I entered the appropriate password

image

Then pressed “Next”

At the next screen, I decided I was going to drop the whole of the database, crossing my fingers, that my NSP will still stay in tact. So I checked the “Drop Whole Database” checkbox.

image

At the next screen, I chose to remove the CE2 database software, again hoping it would retain my original MAXDB 7.6 version, installed during the NSP. So I checked the “Remove Database Client Software” option.

image

Then “Next”

Nothing to change in the Summary. If you did want to change anything, then simply check the relevant section, and the uninstall process will return to it.

image

So, “Next”, and off it went. Time 17:51

image

At 17:53 i get this error message

image

I simply chose “Retry”, as I always do, and off it went again, all the way to completion.

it hangs around on phase 9, with a lot of disk activity

At 18:29, i eventually get the uninstall success message

image

i click “OK”, and the main screen disappears too.

 

Here is my MMC after the uninstall, but before a reboot

image

I re-booted my system, and here is the MMC after the reboot

A closer look at the Windows Services

and

image

A quick lookie at the Windows Users, for curiosity sake

image

Below, you can see the “CE2” directory structure remained. There are no files in any of the sub directories below “CE2”. You can simply delete the “CE2” directory.

image

 

A search through the whole Windows Registry of the Computer returns no findings for “CE2”

image

To be sure, I checked the registry search again, this time with a system I know is present, my NSP, so I searched using the string “NSP”

image

As you can see above, it found it. This leaves me confident that there is no information remaining on the system regarding my previous “CE2” registration search. 

The last remaining reminiscents can be found in the “C:Program Filessapinst_instdir”, where install and uninstall information such as logs, can be found.

image

 

The whole of the “sapinst_instdir” directory can be deleted, if you are happy with your installs and uninstalls. Above is a give-away where you can see my various system installs.

That’s it. After clearing out the recycle bin, there should be no evidence of a CE2 install.

    Hello Gingle,

    it’s very helpful your “Full Monty”. Now one question: why do you uninstall the CE2 ? I want to do BI-IP but it’s only possible with ABAP and Java Stack ? Do you have experience to install both stacks on Trial Basis ?

    have fun

      hi julian
      there are a couple of reasons.
      1. i tried using and configuring the CE1 as a java stack for BEx, but never got the Java Stack config right. I spent days on it, and was failing towards one of the final steps.

      2. i then did not persist because of newer technology. i.e BObj stuff. I thought I would try these offerings first

      3. the Java stack consumes so much RAM, around, 1.5GB, it is impossible for me to have both ABAP and JAVA stacks running on a virtual machine, with only 1.5GB RAM allocated to it, which is the most under a 32bit Windows OS with VirtualBox.

      so, all in all, it was just too difficult

      sorry, about the answer, as it is not what i hoped either. i would be very interested to hear from you, if you decide to give it a go and succeed

      cheers

    Hi Gingle,

    thanks fo r you answer. At the moment I have no time for trying to install the Java stack for BI-IP but in October I’m on the TechEd in Las Vegas and I’ll ask some guys regarding a solution. When I’m back home I’ll inform you.

    Problem: BI-IP needs a lot of RAM and with Win 7 you have the possiblity to address only 3 GB. With win 7 x64 you can address the full amount of RAM in your system. I’ll ask the guys reagrding a x64 Trial.
    Have fun
