常用命令总结
1、增加表空间：
（1）、查看表空间对应数据文件（包括哪些文件，具体大小，是否允许自动扩展）
SQL> select file_name,bytes/1024/1024 as mb, AUEXTENSIBLE from dba_data_files where tablespace_name='APPS_TS_TX_DATA';
（2）、根据具体情况添加数据文件
SQL> ALTER TABLESPACE APPS_TS_TX_IDX ADD DATAFILE '+DATA' SIZE 10240M AUEXTEND OFF;
ALTER TABLESPACE PCBAMES_X ADD DATAFILE '/u01/app/oracle/oradata/PCBATEST/mes_idx04.dbf' SIZE 8192M AUEXTEND OFF;
alter database datafile '+DATA/prod/datafile/apps_ts_tx_idx.621.995105027' auextend on;
ALTER TABLESPACE TS_SCC_EKPTEST ADD DATAFILE '/ekp_databak/ekp_db_backup/20161107data/data/ekp_data113.dbf' size 32767m AUEXTEND OFF;
ALTER TABLESPACE APPS_TS_TX_DATA ADD DATAFILE '/u02/ASCP/oraascp/db/apps_st/data/a_txn_data15.dbf' SIZE 16720M AUEXTEND OFF;

2、创建direcry目录
SQL> create or replace direcry DIRECRY_NAME as 'PATH';
SQL> grant write,read on direcry DIRECRY_NAME USERNAME;
SQL> select * from dba_direcries where direcry_name='EXPDPOGG';
3、控制文件科学计数处理
SQL> set num 50
SQL> select CURRENT_SCN from v$database;
3、恢复目录script
https://www.cnblogs.com/eastsea/p/4181114.html
4、view report group_name查看进程运行状态（日志所在位置为./dirrpt/...）
5、备份归档日志，删除两个小时前的归档
backup archivelog all format '/u03/prod/backupset/ARC_%s_%T' ;
delete noprompt archivelog all completed before 'SYSDATE-2/24' ;
6、查看用户下的所有表和视图
SELECT OBJECT_NAME,OBJECT_TYPE FROM DBA_OBJECTS WHERE OBJECT_NAME LIKE 'SCC_%' AND OBJECT_TYPE='TABLE' AND OWNER='SCCMES' ;
SELECT OBJECT_NAME,OBJECT_TYPE FROM DBA_OBJECTS WHERE OBJECT_NAME LIKE 'SCC_%' AND OBJECT_TYPE='TABLE' AND OWNER='VIEW' ;
6、恢复归档日志
RAC环境下需要加上Thread Number，不加默认是Thread 1
RMAN> restore archivelog from sequence 112 thread 2;
恢复全部归档日志文件
RMAN> restore archivelog all;
恢复Sequence范围
RMAN> restore archivelog from sequence 90 until sequence 98;
RMAN> restore archivelog sequence between 20 and 35;
恢复从第5个归档日志起
RMAN> restore archivelog from sequence 5;
RMAN> restore archivelog low sequence 5;
恢复7天内的归档日志
RMAN> restore archivelog from time 'sysdate-7';
RMAN> restore archivelog until sequence 110;
RMAN> restore archivelog high sequence 108;
改变恢复到另外路径下 则可用下面语句
set archivelog destination '/u01/backup';
RMAN> run
2> {allocate channel c1 type disk;
3> set archivelog destination '/u01/backup';
4> restore archivelog all;
5> release channel c1;
6> }
根据时间查看需要的备份集：
RMAN> list backup of archivelog time between "to_date('2014-04-24 11:00:00','yyyy-mm-dd hh24:mi:ss')" and "to_date('2014-04-24 14:30','yyyy-mm-dd hh24:mi:ss')";
恢复指定时间段
RMAN> run {
set archivelog destination '/u01/backup';
SQL 'ALTER SESSION SET NLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"';
restore archivelog time between '2014-04-24 11:00:00' and '2014-04-24 15:00:00';
}
7、查看用户权限及角色
https://www.cnblogs.com/zhangkaimin/p/7919327.html
查看一个用户的所有权限及角色
select privilege from dba_sys_privs where grantee='TQCS'
union
select privilege from dba_sys_privs where grantee in
(select granted_role from dba_role_privs where grantee='TQCS' );
查看用户拥有的角色
select * from dba_role_privs where GRANTEE='ERP';
8、删除无效备份
crosscheck backup;
delete noprompt expired backup ;
crosscheck archivelog all;
delete noprompt expired archivelog all;
9、查看表结构
https://blog.csdn.net/newhappy2008/article/details/34823339(DBMS_METADATA.GET_DDL用法大全)
https://www.iteye.com/blog/czmmiao-1267194 (dbms_metadata.get_ddl的用法)
SQL> SET LONG 3000
SQL> SET PAGESIZE 0
SQL> SELECT DBMS_METADATA.GET_DDL('TABLE','TABLE_NAME','USER_NAME') FROM DUAL;
SELECT DBMS_METADATA.GET_DDL('TABLE','PANEL_BLOCK_TRACE','PCBAMES') FROM DUAL;
PCBAMES.PANEL_BLOCK_TRACE
select dbms_metadata.get_ddl('INDEX','INDEX_NAME','USER_NAME') from dual;
导出某个用户下的指定表的索引
set pagesize 0
set long 90000
set feedback off
set echo off
spool get_index_ddl.sql
SELECT _char(DBMS_METADATA.GET_DDL('INDEX',u.index_name)) FROM USER_INDEXES u where u.table_name in ('');
spool off
导出某个用户下的指定表
set pagesize 0
set long 90000
set feedback off
set echo off
spool get_index_ddl.sql
SELECT _char(DBMS_METADATA.GET_DDL('TABLE',u.table_name))FROM USER_TABLES u where table_name in ('');
spool off
查看oracle单个数据表包含的索引
select * from dba_indexes where table_name='' and owner='' ;
select INDEX_TYPE,INDEX_NAME,uniqueness from dba_indexes where owner='SCOTT' and table_name='EMP';
根据索引名查看索引包含的字段
select * from dba_ind_columns where index_name = 'INDEXS_NAME' and index_owner='';
select INDEX_NAME from dba_indexes where table_name='INDEXS_NAME' and owner='' ;
col uniquenes for a50;
col column_name for a60;
SELECT i.index_name,
i.index_type,
i.table_name,
i.uniqueness,
i.status,
c.column_name
FROM dba_indexes i, dba_ind_columns c
WHERE i.index_name = c.index_name and i.table_name='EMP' and i.owner='SCOTT';
select table_name,column_name from dba_ind_columns where index_name='PK_APPLOG' and index_owner='ZTEAS04';
select TABLE_NAME,INDEX_NAME,COLUMN_NAME from user_ind_columns where TABLE_NAME='T_BD_CUSTOMER';
10、nohup ,jogs,fg,bg
https://blog.csdn.net/q_l_s/article/details/44117969
nohup sh 1.sh > 1.log 2>&1 &
jogs 查看后台执行的job
jogs -l 查看后台执行的job(命令的序号)
fg %n 让后台运行的进程n到前台来（"n"通过jobs命令查到的后台正在执行的命令的序号(不是pid)）
bg %n 让进程n到后台去 （"n"通过jobs命令查到的后台正在执行的命令的序号(不是pid)）
solaris:sp %num
redhat:kill %num (通过ps命令查看job的进程号（PID，假设为pid），然后执行kill pid )
11、oracle 查看表空间有哪些用户 :
select distinct s.owner from dba_segments s where s.tablespace_name ='PCBAMES_D';
select distinct s.owner from dba_segments s where s.tablespace_name ='PCBAMES_X'
查询表空间包含的对象
SELECT t.owner, t.segment_name,SUM(bytes)/1024/1024 From dba_segments t
WHERE t.tablespace_name = 'PCBAMES_D'
GROUP BY t.owner,t.segment_name
ORDER BY SUM(bytes) desc;
13、空间查询
https://blog.csdn.net/jzw230726/article/details/78542673
查询某个具体的表所占空间的大小
select t.segment_name, t.segment_type, sum(t.bytes / 1024 / 1024) "占用空间(M)"
from dba_segments t
where t.segment_type='TABLE'
and t.segment_name='AD_DATA_FILES'
group by OWNER, t.segment_name, t.segment_type;

14、oracle字符集
15关于数据库的无效对象
https://www.cnblogs.com/kerrycode/p/3723715.html
15、nomount报错怎么解决
从RAC集群复制过来的Oracle程序目录，在变成单节点的时候，需要数据库用户执行这些步骤
使用一个已经安装了AIX 6.1+HACMP+ORACLE RAC 10.2.0.5 环境创建备份,然后在一个新的POWER 5上使用这个备份进行操作系统全恢复.系统恢复后,ORACLE的环境已经有了,现在需要在这个环境下建立一个single db(单实例DB).
笔者尝试通过手工建立单实例DB的方法,启动数据库实例到nomount状态时,报错:
SQL> startup nomount;
ORA-29702: error occurred in Cluster Group Service operation
无法进行下面的数据库创建工作.
fix:
Relink Oracle disable Parallel Server Option:
$ cd $ORACLE_HOME/rdbms/lib
$ make -f ins_rdbms.mk no_parropt
$ make -f ins_rdbms.mk install
16、Solaris中获取硬件以及系统配置信息
http://haibing.org/?p=89 （最全面）

#showrev
CPU
# prtdiag -v 查看CPU及内存总数， 在 /usr/platform/sun4v/sbin 路径下使用root用户查看
双核的会显示
CPU socket #0
CPU socket #1
而单核的只会显示一个
#mpstat 显示CPU逻辑核心数（线程）
#psrinfo 显示CPU逻辑核心数（线程）
#psrinfo -v 具体CPU逻辑核心详细信息
#psrinfo -p 物理CPU数
#psrinfo -vp 物理CPU详细信息
内存
# prtconf|head -n 5
# prtconf|grep 'Memory'
#prtconf | grep -i mem
硬盘
# iostat -E
# 总核数 = 物理CPU个数 X 每颗物理CPU的核数
# 总逻辑CPU数 = 物理CPU个数 X 每颗物理CPU的核数 X 超线程数

allocate channel c3 type disk;
allocate channel c4 type disk;
allocate channel c5 type disk;
allocate channel c6 type disk;
backup full tag 'dbfull' format '/90.50/20181211/ascp_data%U' database
include current controlfile;
sql ‘alter system archive log current’; #在数据库进行全备份完成之后，需要执行该条命令将当前日志归档，备份归档日志时应该包括最后生成的归档
backup filesperset 3 format ‘/backup/arch%u_%s_%p’#filesperset 3设定每个备份集里文件不超过3个
archivelog all delete input; #备份归档可选，可以单独定期备份

}
31、mount -F nfs -o rw,hard,nointr,noac,vers=3,rsize=32768,wsize=32768 10.10.90.50:/u05/bak1 /90.50
32、
将Oracle数据库设置为归档模式及非归档模式
一、将Oracle数据库设置为归档模式
1)sql>shutdown normal/immediate;
2)sql>startup mount;
3)sql>alter database archivelog;
4)sql>alter database open;
5)archive log list;
注意：show parameter log_archive_dest查看归档日志的存放位置。
二、将Oracle数据库设置为非归档模式
1)、关闭数据库
shutdown immediate
2)、再后面把数据库启动到mount的模式
startup mount
3)、关闭flash闪回数据库模式，如果不关闭的话，在后面关闭归档日志的时候就会出现讨厌的ora-38774错误。
alter database flashback off
4)、接着把数据库改为非归档模式
alter database noarchivelog;
5)、都修改好了以后，然后打开数据库
alter database open;
6)、察看一下归档日志的空间大小
select * from v$recovery_file_dest;
接着看一下log日志的状态
select * from v$log;
再看一下闪回日志使用状况
select * from v$flash_recovery_area_usage;
zip -r abc.zip abc
7za x tech_st.zip -r -o/u04/ASCP/oraascp/db/ (-o表示后面接路径后面不能有空格)
set timing on
改数据库名字（要在mount模式下改，改完记得改参数文件中名字）
nid target=sys/oracle dbname=test2
sys@ora10g> alter session set nls_date_format='yyyy-mm-dd hh24:mi:ss';
sys@ora10g> select name,completion_time,status,sequence# from gv$archived_log;
ALTER table SCC.scc_wip_issue_pr_line rename scc_wip_issue_pr_line_1216; (后面不用接用户名)

联机分析处理（OLAP,On-line Analytical Processing），数据量大，DML少。使用数据仓库模板
联机事务处理（OLTP,On-line Transaction Processing），数据量少，DML频繁，并行事务处理多，但是一般都很短。使用一般用途或事务处理模板。
决策支持系统（DDS，Decision support system)，典型的操作是全表扫描，长查询，长事务，但是一般事务的个数很少，往往是一个事务独占系统。

LOB字段是Oracle数据库用于存储大数据对象的字段类型，包括BLOB、CLOB、NLOB、BFILE；
当LOB字段大小超过4k时，数据库会单独为该LOB字段分配额外的BLOB Segments存储BLOB对象，存储在lobsegment中的lob缺省不在缓冲区缓存，对于lob的读写都是物理IO，代价非常高，所以对于大于4kb的lob字段更新效率非常低；
被删除或更新的BLOB字段所占用空间不会自动批量回收，当所在表有大量的删除、更新操作时，BLOB所在Segments会迅速耗尽空间，新的INSERT需要空间时，会在高水位线上加锁后，回收曾使用但已经过期的BLOB空间，由于该操作效率很低，此时数据库就会有大量的‘enq:HW – contention’等待，相关SQL会由于该等待而串行执行，业务受影响十分严重。因此LOB字段不适合在有大批量删除、更新操作的并发场合使用；

二、勒索病毒防范及处理措施
勒索病毒种类较多，以今天电子邮件中的勒索病毒为例，相关防范措施如下：
1、发件箱后缀末尾为“ .casa ”，一律拒收（由IT邮件管理员进行系统设置）或删除，并清空邮箱的“废纸篓”；
2、不明邮件带有附件或链接，切勿点击，除非核实清楚邮件来源；
3、邮件内容可能会仿冒可信的公司或机构，伪造一些用户感兴趣的内容吸引收件人的关注和操作，收件人应保持警惕，可疑邮件应联系相关方核实；
4、一旦中招，立即断网或关机（云桌面），避免病毒通过网络传染至其他用户，然后联系IT处理。

select a.tablespace_name,sqrt(max(a.blocks)/sum(a.blocks))*(100/sqrt(sqrt(count(a.blocks)))) FSFI
from dba_free_space a,dba_tablespaces b
where a.tablespace_name=b.tablespace_name
and b.contents not in ('TEMPORARY','UNDO')
group by a.tablespace_name
order by 2;
数字越小，表空间碎片较多，当小于30%的时候说明碎片程度很可观了。
方法二.查看dba_free_space
dba_free_space 显示的是有free 空间的tablespace，如果一个tablespace的free 空间不连续，
那每段free空间都会在dba_free_space中存在一条记录。如果一个tablespace 有好几条记录，
说明表空间存在碎片，当采用字典管理的表空间碎片超过500就需要对表空间进行碎片整理。
SELECT a.tablespace_name, COUNT (1) 碎片量
FROM dba_free_space a, dba_tablespaces b
WHERE a.tablespace_name = b.tablespace_name
AND b.contents NOT IN ('TEMPORARY', 'UNDO', 'SYSAUX')
GROUP BY a.tablespace_name
HAVING COUNT (1) > 20
ORDER BY 2;
当插入一定量的数据后表空间总量还有剩余但是数据插入报错ora01653，通过下面的语句可看到连续free的空间变得很小
select * from dba_free_space where tablespace_name = 'BIDWD' order by bytes desc;
-- 查看碎片程度高的表
SELECT segment_name table_name , COUNT(*) extents
FROM dba_segments WHERE owner NOT IN ('SYS', 'SYSTEM') GROUP BY segment_name
HAVING COUNT(*) = (SELECT MAX( COUNT(*) ) FROM dba_segments GROUP BY segment_name);

-- 整理表，不影响DML操作
SQL> alter table TABLE_NAME enable ROW MOVEMENT;--启动行移动功能
SQL> alter table TABLE_NAME shrink space compact; --只整理碎片 不回收空间
-- 重置高水位，此时不能有DML操作
SQL> alter table TABLE_NAME shrink space; --整理碎片并回收空间，并调整水位线。业务少时执行
SQL> alter table TABLE_NAME disable ROW MOVEMENT;--关闭行移动
也可以一步到位：
alter table TABLE_NAME shrink space;
shrink 的优势：
不需要重建索引。
可以在线操作。
不需要空闲空间，alter move需要跟当前表一样大小的空闲空间。
注意：
segment shrink执行的两个阶段：
1、数据重组(compact):
通过一系列insert、delete操作，将数据尽量排列在段的前面。在这个过程中需要在表上加RX锁，即只在需要移动的行上加锁。
由于涉及到rowid的改变，需要enable row movement.同时要disable基于rowid的trigger.这一过程对业务影响比较小。
2、HWM调整：第二阶段是调整HWM位置，释放空闲数据块。
此过程需要在表上加X锁，会造成表上的所有DML语句阻塞。在业务特别繁忙的系统上可能造成比较大的影响。
注意：shrink space语句两个阶段都执行。
shrink space compact只执行第一个阶段。
如果系统业务比较繁忙，
可以先执行shrink space compact重组数据,然后在业务不忙的时候再执行shrink space降低HWM释放空闲数据块
报警：
Service check timed out after 60.00 seconds
警告原因：nrpe进程执行某些脚本大于60秒钟，默认10秒钟。
分析：可能是脚本自身执行时间较长，也可能链路造成返回时间较长。如果检查服务器正常，可以将阀值调高点。
修改监控端/usr/local/nagios/etc/objects/commands.cfg文件
#check nrpe
define command{
command_name check_nrpe
# command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -t 60
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -t 70
}
将60调高为70（修改后，对所有的被监控服务器生效；有待寻找对单个被监控服务器生效的办法）

深南电路
在输出时,控制输出结果的缓冲大小由DBMS_OUTPUT.ENABLE控制,buffer size默认为20000,每行最大的限制是32k,后面的一个例子是用来说明存储过程是在缓存了所有数据后才将结果返回。所以当我们使用游标进行输出时，如果结果很多，将会超过这个值报ORA-20000, ORU-10027: Buffer overflow, limit of <buf_limit> bytes这个错误
解决方法：
在存储过程begin后面加 : DBMS_OUTPUT.ENABLE (buffer_size=>null) 表示没有限制

ORA-02449 表中的唯一/主键被外键引用
https://www.cnblogs.com/cici-new/archive/2013/03/04/2942264.html
https://www.cnblogs.com/cici-new/archive/2013/03/04/2942264.html
1.检查哪些表的外键引用了要删除的表的唯一/主键. SELECT a.constraint_name FROM user_constraints a,user_cons_columns b WHERE a.constraint_type = 'R' AND a.constraint_name = b.constraint_name AND a.table_name = '大写表名字';
select A.owner,A.constraint_name,a.r_constraint_name
from dba_constraints A, dba_constraints B
WHERE b.table_name = 'REV_CONTROLLED_LOB' and b.owner='PCB'
and a.constraint_type = 'R'
and a.r_constraint_name = b.constraint_name;
2.生成所有引用要删除表的外键的创建语句.
select 'select dbms_metadata.get_ddl(''REF_CONSTRAINT'',''' ||
A.CONSTRAINT_NAME || ''',''' ||A.owner || ''') FROM DUAL;'
from dba_constraints A, dba_constraints B
WHERE b.table_name = 'REV_CONTROLLED_LOB' and b.owner='PCB'
and a.constraint_type = 'R'
and a.r_constraint_name = b.constraint_name;
3.执行步骤2中产生的SQL语句,获取外键定义.
set long 3000
set linesize 3000
set pagesize 300
执行步骤2产生的语句.
4.删除表.
drop table mytest cascade constraints;
5.删除并重建表.
6.建立因创建该表所删除的外键约束.
执行步骤3中获取到的sql语句.
7.检查各外键是否得到恢复,系统是否正常.
select * from v$dataguard_stats //查看dataguard延时
删除外键
alter table 表名 drop constraint 外键名;
create table class_inf
(CLASSID number not null primary key );
create table student_inf
(
STUDENTID number not null primary key ,
STUDENTNAME nvarchar2(20) ,
GENDER nvarchar2(20) ,

删除共享内存：
export =对应相关实例
sysresv --确定对应的id ipcrm删除即可
ipcrm删除即可（Shared Memory Segments 用ipcrm -m来删除，Semaphore Arrays用ipcrm -s来删除）
shmall 是全部允许使用的共享内存大小，shmmax 是单个段允许使用的大小。这两个可以设置为内存的 90%。例如 16G 内存，16*1024*1024*1024*90% = 15461882265，shmall 的大小为 15461882265/4096(getconf PAGESIZE可得到) = 3774873。
修改 /etc/sysctl.conf
kernel.shmmax=15461882265 92771293590 123,695,058,120
kernel.shmall=3774873 22649238 3774873
kernel.msgmax=65535
kernel.msgmnb=65535
33691590656
61847529062
15099492
5798205849.6
5798205849/4096
1415577
shmmax设置应足够大，能在一个共享内存段下容纳下整个的SGA，设置的过低可能会导致需要创建多个共享内存段，可能导致系统性能的下降 。
执行 sudo sysctl -p
可以使用 ipcs -l 看结果。ipcs -u 可以看到实际使用的情况
这个问题在linux 64位平台 oracle 9.2到11.2平台都存在。
重新运行建库即可。
SGA、PGA与系统内存三者间的关联，目前有一个相对通用的计算规则：
对于OLTP数据库，SGA=系统内存*70%*80%，PGA=SGA*(10%~20%)
对于OLAP数据库，SGA=系统内存*80%*60%，PGA=SGA*(45%~65%)
大页(/etc/sysctl.conf中设置 ，sysctl -p生效)
vm.nr_hugepages 推荐值查询脚本Doc ID 401749.1如何设置该值大小Doc ID 361323.1
vm.min_free_kbytes推荐值设置ID 2501269.1
那么能否可以通过/proc/meminfo中的信息来确认数据库使用了hugepages，我这里举例说明：以下是一个Exadata用户的hugepages信息：
#cat /proc/meminfo | grep -i hugepage
HugePages_tal:?? 13007
HugePages_Free:??? 11813
HugePages_Rsvd:???? 3372
HugePages_Surp:??????? 0
Hugepagesize:?????? 2048 kB
从上面的信息可以得出以下结论：当前hugepages一共实际使用了13007-11813=1194个pages （不包括预留的），预留了3372个pages。永远不会使用达到了11813-3372=8841个pages。每个page大小为2M，也就是说有接近16.5G的hugepages内存被浪费了（因为hugepages无法swap，所以不能被其它程序所使用）。换句话说：当前系统使用中或者即将被使用的hugepages的总和为HugePages_tal – HugePages_Free + HugePages_Rsvd=13007-11813+3372=4566个。产生这样令人困惑的结果是因为用户为了省资源，在这台主机上配置了多个数据库实例，但是只有一个实例使用了hugepages。 之所以要提这个事情，是因为在Oracle 11.2.0.3版本以前，如果当前操作系统配置了hugepages，但是数据库实例设置的SGA大小如果比hugepages总的大小还要大，则SGA无法使用hugepages的内存，然后会去使用其它非hugepages的内存，并且在alert中也没有任何信息，进而导致系统内存占用率高，数据库性能非常糟糕。

第一步：建议配置静态监听
LISTENER=
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROCOL=tcp)(HOST=192.168.1.218)(PORT=1521))
(ADDRESS=(PROCOL=ipc)(KEY=extproc))

(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=easdb)
(ORACLE_HOME=/u01/app/oracle/product/11.2)
(SID_NAME=easdb)
)
)
第二步：监听重新加载，检查监听状态
lsnrctl reload
lsnrctl status
第三步：修改local_listener参数
alter system set local_listener='(ADDRESS=(PROCOL=tcp)(HOST=192.168.1.218)(PORT=1521))'
第四步：注册监听
alter system register ;
cd $ORACLE_HOME/network/admin/下添加 如下三行：
NAMES.DIRECRY_PATH= (TNSNAMES, EZCONNECT)
SQLNET.ALLOWED_LOGON_VERSION_CLIENT=8
SQLNET.ALLOWED_LOGON_VERSION_SERVER=8
并对数据中心的账套在sqlplus / as sysdba下，再执行一次密码修改就好了： alter user xxxx identified by xxxx;
解决方法：
在数据库服务器上的$ORACLE_HOME/network/admin/sqlnet.ora文件添加相应参数
注：单实例或RAC都是此目录的sqlnet.ora文件

select * from v$block_change_tracking; --检查是否开启块跟踪
Block Change Tracking（块跟踪）主要用于RMAN备份的增量备份，将自从上一次备份以来数据块的变化记录到block change tracking文件中，相关后台进程CTWR（Change Tracking Writer）, 主要目的是改善增量备份性能，RMAN可以不再扫描整个文件以查找变更数据。第一个0级的增量备份扫描整个datafile。 随后的增量备份使用block changetracking file的信息，只扫描自上次备份以来被标记为change 的block，RMAN 不会对该文件进行备份。。从10g开始提供此功能。
Block change tracking 默认是禁用的，如果备份策略中使用incrementalbackup，那么建议开启block change tracking。 启用后，不需要其他的维护操作。
在备份期间，change tracking会维护已经标记为change 的block 的bitmap 信息
