如何给sqlplus 安装help

<b><FONT face="Comic Sans MS">

</FONT></b>Installing the Help Facility Manually
The Help Facility may be installed manually using the shell script  
$ORACLE_HOME/bin/helpins. Before you run the script, the SYSTEM_PASS environment variable should be set to the SYSTEM schema name and password. For example:  
  
$ setenv SYSTEM_PASS SYSTEM/MANAGER
$ helpins
  
If the SYSTEM_PASS variable is not set, helpins prompts you for the SYSTEM password and loads the help data into the SYSTEM schema. You can also run $ORACLE_HOME/sqlplus/help/helpbld.sql helpus.sql to install the Help Facility. The system user can run the file helpbld.sql and its argument, helpus.sql, in SQL*Plus to create Help Facility Tables. For example:  
  
$ sqlplus system/manager
SQL> @?/sqlplus/admin/help/helpbld.sql helpus.sql

使用时键入help index显示帮助项，然后寻找相应的帮助
