DBCA cannot be run as root - oracle

Question

I'm trying automate DBCA to create a new database. I'm using the box bseller/oracle-standard with Vagrant.
provision.sh
#!/bin/bash
echo 'Import environment variables'
env=$( grep -ic "ORACLE_SID" /etc/profile )
if [ ! $env -eq 1 ] ; then
echo export ORACLE_SID=mydatabase >> /etc/profile
echo export ORACLE_BASE=/u01/app/oracle >> /etc/profile
echo export ORACLE_HOME=/u01/app/oracle/product/11.2/dbhome_1 >> /etc/profile
source /etc/profile
echo export PATH=$PATH:$ORACLE_HOME/bin >> /etc/profile
fi
echo "Connect with user ORACLE"
sudo su -l oracle
echo "Loading environment variables"
source /etc/profile
echo 'Create database mydatabase'
if [ ! -d /u01/app/oracle/oradata/mydatabase ] ; then
dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbName mydatabase -sysPassword mypassword -systemPassword mypassword -scriptDest /u01/app/oracle/oradata/mydatabase -characterSet WE8ISO8859P1
fi
But this script doesn't worked:
$ sh provision.sh
Import environment variables
Connect with user ORACLE
Loading environment variables
Create database mydatabase
DBCA cannot be run as root.
Running all lines from provision.sh in command line. worked!

Answer 1

I am wondering that the line below does not work to run the oracle command inside of a shell script:
sudo su -l oracle
You should wrap your command to get it work:
su -c "dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbName qualidade -sysPassword password -systemPassword password -scriptDest /u01/app/oracle/oradata/qualidade -characterSet WE8ISO8859P1" -s /bin/sh oracle

Answer 2

"Unable to check for available memory"
I fixed in this form:
I go to my other server with OLD installation Oracle (running fine Oracle 11g), then I find 3 files:
oracle_env.csh
oracle_env.sh
nls_lang.sh
becouse this files no exist in new server, I create with the content (path correct) the files
oracle_env.csh
oracle_env.sh
and put this lines into they:
touch /opt/oracle/product/18c/dbhomeXE/bin/oracle_env.csh
echo 'setenv ORACLE_HOME /opt/oracle/product/18c/dbhomeXE
setenv ORACLE_SID XE
setenv NLS_LANG `$ORACLE_HOME/bin/nls_lang.sh`
setenv PATH $ORACLE_HOME/bin:$PATH' >> /opt/oracle/product/18c/dbhomeXE/bin/oracle_env.csh
after second file:
touch /opt/oracle/product/18c/dbhomeXE/bin/oracle_env.sh
echo 'export ORACLE_HOME=/opt/oracle/product/18c/dbhomeXE
export ORACLE_SID=XE
export NLS_LANG=`$ORACLE_HOME/bin/nls_lang.sh`
export PATH=$ORACLE_HOME/bin:$PATH' >> /opt/oracle/product/18c/dbhomeXE/bin/oracle_env.sh
becouse the file nls_lang.sh is very long and have many config about CHARSET, I copy from OLD server to NEW server.
after is necesary config owner/group of this files:
chown oracle:oinstall /opt/oracle/product/18c/dbhomeXE/bin/oracle_env.csh
chown oracle:oinstall /opt/oracle/product/18c/dbhomeXE/bin/oracle_env.sh
chown oracle:oinstall /opt/oracle/product/18c/dbhomeXE/bin/nls_lang.sh
also the file nls_lang.sh require 755:
chmod 0755 /opt/oracle/product/18c/dbhomeXE/bin/nls_lang.sh
is necesary login as user oracle:
su -l oracle
then I go to folder and load vars environment:
cd /opt/oracle/product/18c/dbhomeXE/bin
. ./oracle_env.sh
finally I can run the command dbca:
dbca -createDatabase -silent -gdbName ora18c -templateName XE_Database.dbc -sysPassword YourPWD1 -systemPassword YourPWD1 -dbsnmpPassword YourPWD1 -datafileDestination /opt/oracle/oradata -storageType FS -memoryPercentage 20 -emConfiguration NONE -sampleSchema false -J-Doracle.assistants.dbca.validate.ConfigurationParams=false
and I get the greath result:
[server#petro bin]$ dbca -createDatabase -silent -gdbName ora18c -templateName XE_Database.dbc -sysPassword YourPWD1 -systemPassword YourPWD1 -dbsnmpPassword YourPWD1 -datafileDestination /opt/oracle/oradata -storageType FS -memoryPercentage 20 -emConfiguration NONE -sampleSchema false -J-Doracle.assistants.dbca.validate.ConfigurationParams=false

becouse I need PHP in this servers, I require OCI8, then I run:
/usr/bin/ea-php72-pecl install oci8
/usr/bin/ea-php71-pecl install oci8
/usr/bin/ea-php70-pecl install oci8
when this request:
**Please provide the path to the ORACLE_HOME directory. Use 'instantclient,/path/to/instant/client/lib' if you're compiling with Oracle Instant Client [autodetect] :**
samplelly [ENTER] then this run fine for me...
