SP2-0171: HELP system not available.
手工建库的情况下SQL*Plus的help手册并没有被安装,需要手动安装。
首先确认有下面几个脚本
[oracle@orale help]$ cd $ORACLE_HOME/sqlplus/admin/help/
[oracle@orale help]$ pwd
/u01/app/oracle/product/11.2.0/sqlplus/admin/help
[oracle@orale help]$ ls
helpbld.sql helpdrop.sql helpus.sql hlpbld.sql
使用system用户登录 不要使用as sysdba
[oracle@orale help]$sqlplus system/oracle
