如何给sqlplus 安装help
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
执行附件的help语句
SQL>@$ORACLE_HOME/help.sql
使用：如
SQL> help grant
