用SEHLL删除ORACLE用户！
su oracle -c "${ORACLE_HOME}/bin/sqlplus /nolog" <<EOF
connect / as sysdba
drop user tccs CASCADE
exit
EOF
  ret=$?
  if [[ $ret != 0 ]]
  then
  print "user has delete failed!"
  return $ret
  else
  print "user deleted done."
  fi;


好像这个SHELL搞不定啊！！

------解决方案--------------------
shell脚本如下：

Perl code

#!bin/bash
su - oracle <<EOF
/u01/app/oracle/product/10.2.0/db_1/bin/sqlplus -S / as sysdba
drop user tccs CASCADE; 
exit 
EOF
