Linux与oracle常用命令

1、数据备份DMP文件语句

exp ucr_o2o_audit /o2o#puad@o2odb  file=E:\upload\order_detail_20171204.dmp tables=(t_dc_order_center_detail,t_dc_cb_bs_trade_detail,ts_r_ecs_order,ts_r_trade)

2、查看表空间语句

SELECT a.tablespace_name "表空间名", total "表空间大小", free "表空间剩余大小", (total - free) "表空间使用大小",

total / (1024 * 1024 * 1024) "表空间大小(G)", free / (1024 * 1024 * 1024) "表空间剩余大小(G)",

(total - free) / (1024 * 1024 * 1024) "表空间使用大小(G)", round((total - free) / total, 4) * 100 "使用率 %"

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 ;

3、查看进程数量

ps -ef | grep 'TI_DC_CBSS_TRADE_SUB_ITEM.ctl'

//杀掉进程

kill -9

4、oracle数据库死锁问题查看

//查看死锁语句

SELECT s.username,l.OBJECT_ID,l.SESSION_ID,s.SERIAL#,

l.ORACLE_USERNAME,l.OS_USER_NAME,l.PROCESS

FROM V$LOCKED_OBJECT l,V$SESSION S WHERE l.SESSION_ID=S.SID;

//查看造成死锁的sql语句

select sql_text from v$sql where hash_value in

(select sql_hash_value from v$session where sid in

(select session_id from v$locked_object))

//赋予删除死锁权限

grant alter system to UCR_O2O_AUDIT;

//删除死锁语句

alter system kill session '738,1429';

5、查看存储过程运行状态

//查看运行中的存储过程

select name,locks,pins

from v$db_object_cache

where locks > 0 and pins > 0 and type='PROCEDURE';

//查看正在执行的sql语句

select a.program, b.spid, c.sql_text,c.SQL_ID

from v$session a, v$process b, v$sqlarea c

where a.paddr = b.addr

and a.sql_hash_value = c.hash_value

and a.username is not null;

6、查看压缩文件和txt文件数据量

//查询压缩文件内数据

gzip -dc CANPRDE02018A1707281001001.017.gz | grep '1717072867765807' | more

//查询压缩文件内记录数量

gzip -dc CANPRDE02018A1707281001001.017.gz|wc -l

//查看txt文件数量

wc -l order_info_20171115.txt

###查询最后1000行

cat mylog.log | tail -n 1000

7、jar包自动运行语句

nohup java -jar /home/o2o_kafka/kafka_access/jarfile/consumerOrderDetail.jar >kafka_java.log 2>& 1 &
