INFO: Configuration assistant "Oracle Database Configuration Assistant" failed

*** Starting OUICA ***
Oracle Home set to /home/oracle/product/10
Configuration directory is set to /home/oracle/product/10/cfgtoollogs. All xml files under the directory will be processed

INFO: The "/home/oracle/product/10/cfgtoollogs/configToolFailedCommands" script contains all commands that failed, were skipped or were cancelled. This file may be used to run these configuration assistants outside of OUI. Note that you may have to update this script with passwords (if any) before executing the same.

SEVERE: OUI-25031:Some of the configuration assistants failed. It is strongly recommended that you retry the configuration assistants at this time. Not successfully running any "Recommended" assistants means your system will not be correctly configured.
1. Check the Details panel on the Configuration Assistant Screen to see the errors resulting in the failures.
2. Fix the errors causing these failures.
3. Select the failed assistants and click the 'Retry' button to retry them.

应该是文件权限问题
chown -R oracle:oinstall /u01
chmod -R 775 /u01
我的database文件夹拷贝到了u01中，这样在database目录下./runInstaller即可成功
