• You are running the command below to create the database (note not all parameters are shown in the command below for brevity):

When you receive the error:

   [FATAL] [DBT-50000] Unable to check for available memory 

Environment

Windows Server, Oracle 19c

Cause

The error "[FATAL] [DBT-50000] Unable to check for available memory" occurs during the Oracle Database 19c configuration process, specifically when the Database Configuration Assistant (DBCA) tries to check the available system memory

One of the causes of this issue is a lack of correct permissions on the Oracle folder and its contents

Resolution

1. Verify that the required accounts are present by checking the Security tab of the Oracle folder properties. If any are missing, add them
2. Even if all the accounts are present as expected, select the 'Replace all child objects...' check box and click Apply and 'Yes' at the prompt (see example screenshot below)
3. Once the action completes, reattempt the dbca command
