在ubuntu 18.04上安装oracle 18cxe的问题

Question

我正在尝试配置 Oracle XE，但面临以下问题：

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:~#

这和

/bin/df: unrecognized option '--direct'

有什么关系吗？ 还是别的什么？

Answer 1

感谢上面 alexsander-perusso 的回答，Ubuntu 16.04 上的 oracle-xe-18c 的正确答案是通过添加

 来编辑 

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

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

在

echo "Configuring Oracle Database $ORACLE_SID."

之后的

$PDB_NAME

正下方的线上。

这是该行在编辑后的样子：

$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" 

参考：http://www.eygle.com/archives/2018/11/oracle_18c_19c_dbt_50000.html

我按照此处的说明操作：https://tec600.wordpress.com/2017/06/29/oracle-installation-on-ubuntu-16-04/，并对 18c XE 进行了更改

上述更改后的结果：

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

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].

基本上你需要编辑脚本文件：

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

并添加 Java 类：

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