DBCA fails with errors: [FATAL] [DBT-50000] Unable to check for available memory

DBCA fails with errors: [FATAL] [DBT-50000] Unable to check for available memory

Recently I have installed Oracle 19c Database binary to windows machine. And after that I started DBCA to create database.

In "Configuration options" steps I got memory error. i.e. [DBT-50000] Unable to check for available memory
Earlier I selected 6GB for my SGA but after this error I had selected 1GB only. But still was facing this issue.

Here is the screenshot for the same.

After searching oracle docs for known issue, I found, it's a bug. One can find details about this bug on following oracle notes.

DBCA fails with errors: [FATAL] [DBT-50000] Unable to check for available memory in "Specify configuration option" (Doc ID 2631718.1)

Workaround for this issue is,

Run dbca with "-J-Doracle.assistants.dbca.validate.ConfigurationParams=false" like a bellow command,

$> dbca -J-Doracle.assistants.dbca.validate.ConfigurationParams=false

This will solve your issue and DBCA will run smooth, no issues thn.
