大家好，我是 JiekeXu,分开这么久，很高兴又和大家见面了，祝大家新年快乐，牛气冲天发大财，欢迎点击上方蓝字关注我，标星或置顶，更多干货第一时间到达！
本文 SQL 及相关命令均是在运维工作中总结整理而成的，对于运维 DBA 来说可提高很大的工作效率，值得收藏。当然如果你全部能够背下来那就很牛逼了，如果不能，还是建议收藏下来慢慢看，每条 SQL 的使用频率都很高，肯定能够帮助到你。
当然，由于本编辑器原因以下 SQL 可能出现格式错误不能执行，导致出错，这里将其保存至文本文件中方便复制粘贴执行，如有需要的小伙伴们在本公众号后台回复【SQL大全二】 即可获取，这里也有 2020 年的精华文章汇总，如有需要可点击此处查看【精华文章】。
1、查看数据文件信息：
col file_name for a55
select tablespace_name,file_name,bytes/1024/1024/1024 gb,AUTOEXTENSIBLE
from dba_data_files where tablespace_name='AM_DATA';
alter tablespace AM_DATA add datafile '+DATA' size 30G;
2、查看 ASM 磁盘组信息：

round(free/1024/1024/1024) "Free g",ROUND((total-free)/total,4)*100 "USED%"
FROM (SELECT tablespace_name,SUM(bytes) free FROM
DBA_FREE_SPACE
GROUP BY tablespace_name ) a,
(SELECT tablespace_name,SUM(bytes) total FROM DBA_DATA_FILES
GROUP BY tablespace_name) b
WHERE a.tablespace_name=b.tablespace_name
ORDER BY 4;
5、查某个表空间内的前五个大表

--- 检查PVID
lspv | grep hdiskn
--- 检查保留策略
lsattr -E -l hdisk5 | grep reserve_policy
--- 查看磁盘是否为共享磁盘
lsattr -El hdisk0
比对两个主机对应的磁盘号是否一致：unique_id
--- 查看磁盘是否可用
lspv
看PVID是否为none，若为none则数据库可用，再查看数据库当前有没有使用，若没有则可用来扩容ASM磁盘组
23、AIX 下按用户查看占用多少内存
svmon -U grid -w |more
svmon -U oracle -w | more
24、AIX 下查看用户下有多少进程
svmon -PO unit=GB |grep aioserver |wc
svmon -PO unit=GB |grep oracle |wclsvg |lsvg -i -p
lsdev -c disk
25、查看服务器底层用的存储类型：
lscfg -vpl hdisk40
26、生成AWR报告
-----某个节点的 AWR
@?/rdbms/admin/awrrpti.sql
-----AWR报告
@?/rdbms/admin/awrrpt.sql
-- AWR 两个时间段的比较报告
@?/rdbms/admin/awrddrpt.sql
-----ASH报告
@$ORACLE_HOME/rdbms/admin/ashrpt.sql
-----细粒度的 ASH （Enter value for slot_width:1）slot 槽为 1 的 ASH
@$ORACLE_HOME/rdbms/admin/ashrpti.sql关于physical reads ，db block gets 和 consistent gets 这三个参数之间有一个换算公式：
数据缓冲区的使用命中率=1 - ( physical reads / (db block gets + consistent gets) )。
用以下语句可以查看数据缓冲区的命中率：
SELECT name, value FROM v$sysstat WHERE name IN ('db block gets', 'consistent gets','physical reads');查询出来的结果 Buffer Cache 的命中率应该在 90％ 以上，否则需要增加数据缓冲区的大小。
27、查看ASM磁盘挂载时间：
set lines 500 pages 2000
col g_name format a10
col g_n format 99
col d_n format 999

col h_status format a11
col name format a20
col path format a20
col failgroup format a15
up_number g_n,
g.disk_number d_n,
g.name name,
g.failgroup,
g.mount_status m_status,
g.header_status h_status,
g.mode_status mo_status,
g.path ,
to_unt_date, 'YYYY/MM/DD HH24:MI:SS') m_date
from v$asm_disk g
order by g_n, d_n
28、查看某个用户所拥有的角色
select * from dba_role_privs where grantee='JKX_NEW_QRY ';
29、查看某个角色所拥有的权限
select * from dba_sys_privs where grantee='SKDATA';
select * from DBA_TAB_PRIVS where grantee='SKDATA';
30、修改 LINUX 操作系统 /dev/shm 文件系统大小
开机自启动：
tmpfs /dev/shm tmpfs defaults,size=20G 0 0
立即生效：
mount -t tmpfs shmfs -o size=20g /dev/shm
31、trace 追踪监听文件
$ ps aux |sort -rnk3 |more
侦听器进程的Pstack / Truss / Strace / Tusc 注意110888.1如何跟踪Unix系统调用
Pstack <PID_of_listener> Sun：truss -aefdDo /tmp/truss-lsnr.log -p <PID_of_listener>
Linux：strace -frT -o /tmp/strace-lsnr.log -p <PID_of_listener>
HP：tusc -aef -o /tmp/tusc-lsnr.log -T“％H：％M：％S” -p <PID_of_listener>
32、删除当前目录下十天前 *.dmp 文件
find ./ -name '*.dmp' -mtime +10 -exec rm -f {}
33、dds 同步软件

from v$log_history
where trunc(FIRST_TIME,'dd')>sysdate-10
group by trunc(FIRST_TIME,'dd')
order by 1;
53、查看每天归档产生数据量 归档量
--按天计算
select trunc(FIRST_TIME,'dd') Time,sum(BLOCKS*BLOCK_SIZE)/1024/1024/1024 Total_GB from v$archived_log
group by trunc(FIRST_TIME,'dd') order by 1;
--按小时计算
select trunc(FIRST_TIME,'hh') Time,sum(BLOCKS*BLOCK_SIZE)/1024/1024/1024 Total_GB from v$archived_log
group by trunc(FIRST_TIME,'hh') order by 1;
54、redo 日志产生频率
id,to_char(a.first_time,'yyyy-mm-dd hh24:mi:ss') begin_time,
b.recid,to_char(b.first_time,'yyyy-mm-dd hh24:mi:ss') end_time,
round((b.first_time-a.first_time)*24*60,2) minutes
from v$log_history a,v$log_history b
id = a.recid+1 and to_char(a.first_time,'yyyy-mm-dd hh24:mi:ss') >=to_char(sysdate-10,'yyyy-mm-dd hh24:mi:ss') ;
desc dba_hist_active_sess_history; ----可以查询执行过的sql的主机
55、AIX 查看僵尸进程
ps -ef | grep defunct
56、清理 LOCAL=NO 连接
ps -ef | grep LOCAL=NO | grep -v grep | awk '{print $2}' |xargs kill -9
57、AIX 系统查看错误
errpt | head -20
58、rman 查看归档备份
rman target /
list backup of archivelog all;
59、查看 rman 备份进度
set line 200 pages 1000
col MESSAGE for a60
col TARGET for a20
select sid,SERIAL#,TARGET,START_TIME,ELAPSED_SECONDS,TIME_REMAINING,MESSAGE,ROUND(SOFAR/TOTALWORK*100,2) "%_COMPLETE"
from v$session_longops
where 1=1 --and sid=2983 and SERIAL#=5
and TIME_REMAINING>0 ;
60、查询创建用户的日期
select t.username, t.account_status, t.created, t.default_tablespace from DBA_USERS t
where username= 'ABASE' order ated desc;
61、rman全库备份
run {allocate channel c1 type disk ;allocate channel c2 type disk ;allocate channel c3 type disk ;allocate channel c4 type disk ;backup as compressed backupset database format '/backup/%d_%I_%s_%p.bak';backup as compressed backupset archivelog all format '/backup/%d_%I_%s_%p.arc';backup current controlfile for standby format '/backup/%d_%I_%s_%p.ctl';release channel c1;release channel c2;release channel c3;release channel c4;
}
--压缩全库备份
backup database format='/u01/app/backup/rman/eweaverstb_%s.bak' filesperset 4;
run{
backup as compressed backupset database format='/u01/app/backup/ewverstb_%s.bak' plus archivelog delete input skip inaccessible;
}
62、数据泵导入导出相关命令
--expdp导入导出
select * from dba_directories where directory_name ='DATA_PUMP_DIR';
如果目录过小或者不存在,则
create directory expdp_dir as '/u01/app/backup/expdp_dir';
grant read,write on directory expdp_dir to public;
expdp '/ as sysdba' directory=expdp_dir dumpfile=full_bak.dmp full=y;impdp '/ as sysdba' directory=expdp_dir dumpfile=full_bak.dmp full=y;impdb '/ as sysdba' DIRECTORY=dump_dir DUMPFILE=full.dmp FULL=y;--使用 par 文件全库导出

该参数可以用于impdp,主要作用是未真实在目标端执行导入的情况下,生成sql文件包含该dmp文件的所有ddl语句,使用语法为
SQLFILE=[directory_object:]file_name
注意事项:
1.directory_object可以不和impdp的DIRECTORY参数不一致,如果是一样,directory_object可以省略
2.SQLFILE文件必须写入到磁盘之上,不能写入到ASM中
3.SQLFILE和QUERY参数冲突,不能同时使用--获取创建索引的 SQL

63、查看历史备份
set line 200
col START_TIME for a30
col END_TIME for a30
col status for a10
select SESSION_KEY,
INPUT_TYPE,
STATUS,
to_char(START_TIME, 'yyyy-mm-dd hh24:mi') START_TIME,
to_char(END_TIME, 'yyyy-mm-dd hh24:mi') END_TIME,
ELAPSED_SECONDS / 3600
from v$rman_backup_job_details
where to_char(START_TIME, 'yyyy-mm-dd hh24:mi') > to_char(sysdate-12,'yyyy-mm-dd hh24:mi')
order by SESSION_KEY;
64、查询数据库增量增长
select sum(TABLESPACE_USEDSIZE)*8/1024/1024,substr(rtime,0,10)
from DBA_HIST_TBSPC_SPACE_USAGE
where snap_id in (select max(snap_id) from DBA_HIST_TBSPC_SPACE_USAGE group by substr(rtime,0,10) ) --and TABLESPACE_ID=7
group by substr(rtime,0,10) order by 1 ;
--清空SHARED_POOL缓冲
ALTER SYSTEM FLUSH SHARED_POOL ;
--删除已备份归档
rman target /
delete archivelog all backed up 1 times to device type 'sbt_tape';
关于密码错误验证延迟特性：
密码错误验证延迟，可以通过设置EVENT="28401 TRACE NAME CONTEXT FOREVER, LEVEL 1"
alter system set events='28401 trace name context forever, level 1'; ---不需要重启
65、数据库开启归档
su - oracle
sqlplus / as sysdba
archive log list;1、归档路径
①如果没有归档存放存储，需要操作系统挂载存储再继续操作
②如果归档存储存在，但并非所想存放的实际路径，可在相关存储下创建目录
mkdir -p /app/oracle/arch
修改归档目录权限
chown -R oracle:oinstall /app/oracle/arch③如果归档存储存在，且路径正确，权限正确则可以直接使用2、备份spfile文件
create pfile from spfile;
3、修改归档路径到想存放的位置，如查询出的归档路径已经是正确的位置，则不需要修改。
su - oracle
sqlplus / as sysdba
alter system set log_archive_dest_1='location=/app/oracle/arch' scope=spfile sid='*';
4、重启数据库，开启/关闭归档模式（rac两个节点均关闭，使用一个节点修改，修改完成后启动另一个节点）
shutdown immediate;
startup mount;
5、归档模式修改：
开启归档模式：
alter database archivelog;
关闭归档模式：
alter database noarchivelog;
alter database open;
如果为集群：需要停止两个节点，在一个节点操作完成后，拉起另一个节点，操作步骤如上，
rac集群启动另一个节点：startup6、查看数据库归档路径
su - oracle
sqlplus / as sysdba
archive log list;
切换日志，查看归档目录下产生归档文件
alter system switch logfile；
7、关闭归档
shutdown immediate;
startup mount;
--开启归档模式：
--alter database archivelog;
关闭归档模式：
alter database noarchivelog;
66、 RMAN 全备脚本部署
①RMAN全备脚本部署
vi /home/oracle/full_backup.sh
ORACLE_BASE=/app/oracle
ORACLE_HOME=/app/product/11.2.0/db
ORACLE_SID=JiekeXu1
db_name=JiekeXu
PATH=$PATH:$ORACLE_HOME/bin/v_date=`date +%Y%m%d`
[ -d /backup/$db_name/$v_date ] || mkdir -p /app/backup/$db_name/$v_daterman target /<<EOF > /app/backup/$db_name/$v_date/full_$v_date.log
run{
allocate channel c1 device type disk;
backup database format '/app/backup/%d/%T/full_%d_%T_%s_%p.bak';
sql 'alter system archive log current';
sql 'alter system archive log current';
sql 'alter system archive log current';
backup archivelog all delete input format '/app/backup/%d/%T/full_arch_%d_%T_%s_%p.bak';
backup current controlfile format '/app/backup/%d/%T/full_controlfile_%U';
backup spfile format '/app/backup/%d/%T/full_spfile_%d_%T_%s_%p.bak';
release channel c1;
}
EOF②赋权
chmod +x full_backup.sh
关于 SQL 命令还有很多，由于篇幅就先写这么多，66 条六六大顺，剩余的有机会在分享。上述 SQL 命令由于微信编辑器原因可能出现格式错误不能执行，这里将其保存至文本文件中方便复制粘贴执行，如有需要的小伙伴们在本公众号后台回复 【SQL大全二】 即可获取。
