How to remove netweaver instance completely?

[Former Member]

Hi

During Netweaver 2004 installation on AIX I got error as Wrong or unsupported SAP DB software installation

DB startup failed

To start installation again newly , I deleted /sapdb and /usr/sap./etc/opt/sapdb /usr/spool/sql also all the files in installation folder /local/installsap

and started installation again in different folder.

In new installation it is detecting previous instance as well.

Which files should I remove so as to remove the instance completely?

Hi

If you have a databse maxDB then,

Step1: Go to \sapdb\programs\bin folder and run SDBSETUP.EXE

Step2 Choose remove database option and remove the database.

Step3: Run the installation master and choose uninstall option to remove the instance.

Step1 : is required coz sometimes if you uninstall sap instance from sapinst maxdb database traces are still left which can create problem in your future installation.

Any issues feel free to ask.

Actually I deleted following files allready using command <b>rm -r</b>.

/ssapdb

/usr/sapdb

/etc/opt/sapdb

/usr/spool/sql

/sapmnt/SUN

"SUN" is system id given in previous installation.

Hi

You should not do that.Anyways clean your system check all the folder location so that no trace of your previous maxdb is there.Otherwise you will run into problems during ur next installation.

Try if you face problems i will tell you the exact folder locations where all you have to delete files.

Hi ,

I removed all the folders of previous Netweaver 2004 installation from aix machine, as there was problem in starting server .

In new installation I am getting following error:

ERROR 2007-05-28 10:11:59 [iaxxinscbk.cpp:289]

abortInstallation MDB-07021 Registry information for database software found in system but the software check failed. The software was not properly removed or installed incorrectly.

I have already deleted following folders:

/sapdb

/usr/sapdb

/usr/spool/sql

/sapmnt/

/home/sqdjet

/home/jetadm

Is there any folder remaining to delete?

Please help.
