对于数据库中表空间查看,想必大家都有很多的脚本已经在用了,自己也啰嗦一下,分享一个通过shell脚本查看表空间使用情况的例子。 脚本如下: sqlplus -s $DB_CONN_STR@$SH_DB_SID <<EOF set echo off heading on underline on; column inst_num heading "Inst Num" new_value inst_num format 99999; column inst_name heading "Instance" new_value inst_name format a12; column db_name heading "DB Name" new_value db_name format a12; column dbid heading "DB Id" new_value dbid format 9999999999 just c; prompt prompt Current Instance prompt ~~~~~~~~~~~~~~~~ select d.dbid dbid , d.name db_name , i.instance_number inst_num , i.instance_name inst_name from v$database d, v$instance i;
