Oracle XE 18c create database error "[DBT-50000] Unable to check for available memory" through DBCA

I have just installed Oracle XE 18c on my Windows 8.1 machine.

I am trying to create a new database through Advanced Configuration but when I get to Configuration settings step, it throws an error:

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

I have tried bypassing the validation checks as suggested here but still no luck.

I have also tried creating it through command prompt with:

dbca -createDatabase -silent -gdbName ora18c -templateName General_Purpose.dbc 
-sysPassword sys123 -systemPassword sys123 -dbsnmpPassword sys123 -
datafileDestination /u01/oradata -storageType FS -memoryPercentage 20 -
emConfiguration NONE -sampleSchema false -J-Doracle.assistants.dbca.validate.ConfigurationParams=false

but it also throws in an error saying Oracle not available.

I highly appreciate your help please.

Solution

  • This is fixed in a future build of XE. In the mean time can you try the following.

    1) On your network adapter that you are using, check (enable) "Client for Microsoft Networks" and "File and Printer Sharing for Microsoft Networks".

    2) Check to see if Netbios is enabled on your network connection: See this link for more info:

    3) In some cases, antivirus has interfered with an installation. Try disabling anti-virus and reinstall..

    I'm afraid at this point this is all I can suggest.
