Hi All,

We have uninstalled and installed again successfully.

Hi Sreekanth,

Please check password for user superdba. Looks like password is incorrect.

You may try to reset the password for superdba using SAP note 25591.

Hi Deepak,

We are able to login to database studio with superdba user and password, but when click on anything like data area, log area then its showing same 4008 Unknown user name/password combination error.

Hi Deepak,

I have changed the SUPERDBA password through DBMGUI and restarted the MaxDB, still installation stops at Create database schema for ABAP and throwing same error. If the password changes in DBMGUI how it will recognize by installation.

Hi Sree,

Please setup X-user as per SAP Note 39439 - XUSER entries for SAP DB and MaxDB

Hope this helps.

Hi Deepak,

I have executed the below commands,

xuser -U c -u CONTROL,<password> -d SID -n HOSTNAME -S INTERNAL set

xuser -U w -u CONTROL,<password> -d SID -n HOSTNAME -S INTERNAL set

After execution of the commands i have retry the same installation still i am getting same error.

Kindly suggest,

Regards,

Hi,

we are facing the same issue as you. Could you fix it in the end? If yes, what was the solution?

Thanks!

Hi, just in case someone else is experiencing the same issue. Originally we used a master password with 10 characters. This led to the error during the installation. Inspired by a note (1761717), we tried the installation again with a password having 8 characters and then it worked for us (for whatever reason).

Best regards,

Stefan
