[INS-20802] Oracle Database Configuration Assistant failed. Cant Install 19c Database..

4232913

Hello everyone,

So a while ago I installed the 19c database. But for some reason I deleted it. And when I try to download it again its showing me a configuration assistant failed error. When I deleted it, I deleted everything, the environment variables, the groups and the registries and I cleared temp and the recycling bin. I dont know why this is happening.. I need to download fast so I can work on my university project.

It shows a fatal error in the logs: [FATAL] ORA-12560: TNS:protocol adapter error.

Hope someone helps Been trying to solve this for a week and nothing on google helps..

What are you doing, which OS do you use, which step in DBCA does make a problem? To help you we need a lot more information.

I'm trying to install the oracle database 19c. I'm using windows 10 and I think the step is while doing the Database Configuration Assistant. I'm new to oracle so i don't know what DBCA is?

Hello. I have the similar question. While installing a database, I have the same question "[INS-20802] Oracle Database Configuration Assistant failed". When I had seen logs I saw that the problem is next "Error in Process: d:\Databases\Oracle\perl\bin\perl.exe"

I reviewed all the Internet but I couldn't find the solution.

Windows 7 64-bit, Oracle 12c.

thanks in advance

Pleae check "PATH" and "ORACLE_HOME" settings at the environment variables.

I've checked. The variable "PATH" exists and has the path to the place where the oracle (means not database location) was installed (i.e. d:\Databases\Oracle\bin ). But I couldn't find the variable "ORACLE_HOME". I created it myself and pointed the path d:\Databases\Oracle\. Actually, I don't know it's the correct path or not. But, anyway, I have the same mistake, i.e. "Error in Process: d:\Databases\Oracle\perl\bin\perl.exe".

If you need a running database quickly, use this Virtualbox Appliance:

Thanks. It's come in handy me. But, anyway I would like to learn the install process and find out what the problem is.

Did you select to create a database at the time of installing the Oracle Software, or did you select to install Software Only, then manually launch DBCA afterward to create the database?

Hi,

Please share us your error log wit more information for better understanding.

FYI - Check the bash profile config, Your ORACLE_SID, ORACLE_BASE, ORACLE_HOME & PATH has to be set properly environment variable.

If not try to re-config by using the DBCA.

Warm Regards,
