Issue in installing oracle 18cxe on ubuntu 18.04

Question

I am trying to configure Oracle XE but am facing the below issue:

root@venky-Lenovo-G510:~# /etc/init.d/oracle-xe-18c configure

/bin/df: unrecognized option '--direct' 
Try '/bin/df --help' for more information.
Specify a password to be used for database accounts.
Oracle recommends that the password entered should be at least 8
characters in length, contain at least 1 uppercase character, 1 lower

case character and 1 digit [0-9]. Note that the same password will be

used for SYS, SYSTEM and PDBADMIN accounts:
Confirm the password:
Configuring Oracle Listener. Listener configuration succeeded.
Configuring Oracle Database XE.
****[FATAL] [DBT-50000] Unable to check for available memory.****


Database configuration failed. Check logs under '/opt/oracle/cfgtoollogs/dbca'.

root@venky-Lenovo-G510:~#

Is this anything related to /bin/df: unrecognized option '--direct'? Or something else?

Looks like you might have some dependencies missing ... binutils springs to mind. – Bron

I'm not sure Oracle 18c XE is supported on Ubuntu. It doesn't appear on the list of supported distributions here: docs.oracle.com/en/database/oracle/oracle-database/18/ladbi/… – Stantonstanway

i have converted the rpm to deb and installed it – Briggs

Thanks to alexsander-perusso's answer above, the correct answer for oracle-xe-18c on Ubuntu 16.04 is to edit /etc/init.d/oracle-xe-18c by adding

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

on the line directly below echo "Configuring Oracle Database $ORACLE_SID." after $PDB_NAME.

Here is what the line looks like after the edit:

$SU -s /bin/bash  $ORACLE_OWNER -c "(echo '$ORACLE_PASSWORD'; echo '$ORACLE_PASSWORD'; echo '$ORACLE_PASSWORD') | $DBCA -silent -createDatabase -gdbName $ORACLE_SID -templateName $TEMPLATE_NAME -characterSet $CHARSET -createAsContainerDatabase $CREATE_AS_CDB -numberOfPDBs $NUMBER_OF_PDBS -pdbName $PDB_NAME -J-Doracle.assistants.dbca.validate.ConfigurationParams=false -sid $ORACLE_SID -emConfiguration DBEXPRESS -emExpressPort $EM_EXPRESS_PORT -J-Doracle.assistants.dbca.validate.DBCredentials=false -sampleSchema true $SQLSCRIPT_CONSTRUCT $DBFILE_CONSTRUCT $MEMORY_CONSTRUCT"

I was following the instructions here: https://tec600.wordpress.com/2017/06/29/oracle-installation-on-ubuntu-16-04/ with changes for 18c XE

Results after the above changes:

$sudo /etc/init.d/oracle-xe-18c configure
/bin/df: unrecognized option '--direct'
Try '/bin/df --help' for more information.

Does anyone know the equivalent fix for installing on Windows 10 Pro ? – Miscount

the same modification works with Ubuntu 20.04 LTS as well. – Radiolarian

Answer 2

Basically you need to edit the script file with:

sudo nano /etc/init.d/oracle-xe-18c  

And add the Java class:

-JDoracle.assistants.dbca.validade.ConfigurationParams=false

See: https://www.youtube.com/watch?v=RcZLD2l6WTw

You got a typo there -J-Doracle.assistants.dbca.validate.ConfigurationParams=false – Insensibility
