3、asm、grid、oracle安装

1、执行oracle-csh.txt  
 上面执行了
2、安装依赖包
yum -y install binutils compat-libcap1 compat-libstdc* gcc gcc-c++* glibc glibc-devel ksh libgcc libstdc libaio libaio-devel make elfutils-libelf-devel sysstat

3、配置主机名称和hosts 配置ssh 互通
hostnamectl set-hostname lsrkzyk1
hostnamectl set-hostname lsrkzyk2

cat <<EOF >> /etc/hosts

#pub
80.128.0.202     lsrkzyk1  
80.128.0.203     lsrkzyk2

ssh oracle@80.128.0.203 date

ssh oracle@lsrkzyk1 date
ssh oracle@lsrkzyk2 date

ssh oracle@lsrkzyk1p date
ssh oracle@lsrkzyk2p date


5、配置grid 环境变量 和 oracle 环境变量
su - grid
vi .bash_profile

ORACLE_SID=+ASM1; export ORACLE_SID
ORACLE_BASE=/u01/grid_base; export ORACLE_BASE
ORACLE_HOME=/u01/grid/11.2; export ORACLE_HOME
GRID_HOME=/u01/grid/11.2; export GRID_HOME
THREADS_FLAG=native; export THREADS_FLAG
PATH=$ORACLE_HOME/bin:$PATH; export PATH
export LANG=en_us.UTF-8


su - oracle
vi .bash_profile

ORACLE_BASE=/u01/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.4/db_1; export ORACLE_HOME
ORACLE_SID=lsrkzyk1; export ORACLE_SID
export ORACLE_UNQNAME=msrkzyk
TNS_ADMIN=$ORACLE_HOME/network/admin; export TNS_ADMIN
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
export NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"
export NLS_DATE_FORMAT="yyyy-mm-dd hh24:mi:ss"
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
export LANG=en_us.UTF-8


当rac2节点配置完毕以后，修改oracle 、grid用户下的环境变量:

[root@node2 network-scripts]# vi /home/oracle/.bash_profile

将ORACLE_SID=snrk1 改为ORACLE_SID=snrk2

[root@node2 network-scripts]# vi /home/grid/.bash_profile

将ORACLE_SID=+ASM1 改为ORACLE_SID=+ASM2

统统设置完成后，建议重启一下第2 个节点。



---------asmlib方法一

6、安置oracle ASMlib  配置 ASM 磁盘

wget http://10.64.39.210/asmlib/asmlib.repo -P /etc/yum.repos.d/
yum clean all
yum install -y oracleasm-support oracleasmlib oracleasm


7、对共享磁盘进行分区
parted /dev/sdc
mklabel gpt
mkpart primary 20G  520G 
mkpart primary 520G  1020G 
mkpart primary 1020G  1520G 
mkpart primary 1520G  2020G 
mkpart primary 2020G  2520G 
mkpart primary 2520G  3020G 
mkpart primary 3020G  3520G 
mkpart primary 3520G  4020G 
mkpart primary 4020G  4520G 
mkpart primary 4520G  5020G 
mkpart primary 5020G  5520G 
mkpart primary 5520G  6020G 
mkpart primary 6020G  6520G 
mkpart primary 6520G  7020G 
mkpart primary 7020G  7520G 
mkpart primary 7520G  8020G 
mkpart primary 8020G  8520G 
mkpart primary 8520G  9020G 
mkpart primary 9020G  9520G 
mkpart primary 9520G  10020G 
mkpart primary 10020G  10520G 
mkpart primary 10520G  11020G 
mkpart primary 11020G  11950G 
p
quit

8、root 用户配置 ASMLib
先重启一下
/etc/init.d/oracleasm configure
grid
asmdba
y
y

9、设置共享磁盘
节点1

/usr/sbin/oracleasm createdisk OCR_VOTE /dev/sdb1
/usr/sbin/oracleasm createdisk ASMDATA /dev/sdb2
/usr/sbin/oracleasm createdisk BACKUP /dev/sdb3

节点2（rac2）上以root用户登录，使用scandisks命令扫描已经创建的ASM磁盘
也就是说，我们只需要在节点 1 上创建 ASM 磁盘，其他节点不需要。


/etc/init.d/oracleasm scandisks

Scanning the system for Oracle ASMLib disks:               [  OK  ]

/etc/init.d/oracleasm listdisks

ASMDATA
BACKUP
OCR_VOTE

ASM磁盘组配置完成。

systemctl status oracleasm
systemctl restart oracleasm
systemctl daemon-reload

cd /usr/lib/modules


10、下载gird和oracle包
mkdir -p /home/grid/soft
mkdir -p /home/oracle/soft

wget -P /home/grid/soft http://10.64.39.210/download/p13390677_112040_Linux-x86-64_3of7.zip

wget -P /home/oracle/soft http://10.64.39.210/download/p13390677_112040_Linux-x86-64_1of7.zip

wget -P /home/oracle/soft http://10.64.39.210/download/p13390677_112040_Linux-x86-64_2of7.zip


chown -R grid:oinstall /home/grid/soft
chown -R oracle:oinstall /home/oracle/soft

11、安装cvu包

rac1和rac2节点上以 root 用户身份安装操作系统程序包cvuqdisk-1.0.9-1.rpm，此包位于grid安装包下rpm目录下。

rpm -ivh http://10.64.39.210/download/cvuqdisk-1.0.9-1.rpm
yum install -y http://10.64.39.210/download/compat-libstdc++-33-3.2.3-72.el7.x86_64.rpm
rpm -ivh --force --nodeps http://10.64.39.210/download/pdksh-5.2.14-30.x86_64.rpm

12、rac1和rac2使用CUV验证硬件和操作系统配置

进入解压完毕的grid安装包目录下，执行

su - grid

cd grid

/home/grid/soft/grid/runcluvfy.sh stage -post hwos -n lsrkzyk1,lsrkzyk2 -verbose


lsrkzyk1和lsrkzyk2执行集群预检查


/home/grid/soft/grid/runcluvfy.sh stage -pre crsinst -n lsrkzyk1,lsrkzyk2 -verbose

全部为pass即通过，个别的如 dns  没通过（failed）可以忽略。

1、安装acfs
find / -name acfsroot 
/u01/grid/bin/acfsroot install
2、启动acfs
find / -name acfsload
/u01/grid/bin/acfsload start -s

ora-12547:TNS:lost contact

--或者client连接报ora-12537:TNS:connection closed

1、检查两节点oracle、grid用户组 是否有asmdba dba oinstall
2、赋予oracle.grid 权限 
chmod 6755  $ORACLE_HOME/bin/oracle
--chmod 6755 /u01/grid/bin/oracle
 
--------------------------------
--最后配置

cat <<EOF>> /etc/rc.local

--orqcle用户过期处理 （方法一）
--查看数据库密码过期时间

sqlplus / as sysdba

select * from dba_profiles where profile='DEFAULT' and resource_name='PASSWORD_LIFE_TIME';
alter profile default limit password_life_time unlimited;
修改前已经过期了的需要再次修改密码。
alter user  user_name identified by user_passwd;

__________________________________
--解决密码过期（sys用户） （方法二）
1、创建一个profile（相当于创建一个角色）
create profile  passwd_unlimit limit  PASSWORD_LIFE_TIME unlimited;
ALTER profile  passwd_unlimit limit COMPOSITE_LIMIT          UNLIMITED; 
ALTER profile  passwd_unlimit limit SESSIONS_PER_USER        UNLIMITED; 
ALTER profile  passwd_unlimit limit CPU_PER_SESSION          UNLIMITED; 
ALTER profile  passwd_unlimit  limit CPU_PER_CALL             UNLIMITED; 
ALTER profile  passwd_unlimit  limit LOGICAL_READS_PER_SESSION UNLIMITED; 
ALTER profile  passwd_unlimit  limit LOGICAL_READS_PER_CALL   UNLIMITED; 
ALTER profile  passwd_unlimit limit IDLE_TIME                UNLIMITED; 
ALTER profile  passwd_unlimit limit CONNECT_TIME             UNLIMITED; 
ALTER profile  passwd_unlimit  limit PRIVATE_SGA              UNLIMITED; 
ALTER profile  passwd_unlimit limit FAILED_LOGIN_ATTEMPTS    10      ; 
ALTER profile  passwd_unlimit limit PASSWORD_REUSE_TIME      UNLIMITED; 
ALTER profile  passwd_unlimit limit PASSWORD_REUSE_MAX       UNLIMITED; 
ALTER profile  passwd_unlimit  limit PASSWORD_VERIFY_FUNCTION NULL    ; 
ALTER profile  passwd_unlimit  limit PASSWORD_LOCK_TIME       1       ; 
ALTER profile  passwd_unlimit  limit PASSWORD_GRACE_TIME      7       ; 

2、用户改成这个角色
alter user  SCRK5109_QRY  profile   passwd_unlimit; 
3、查看用户角色
SELECT  *  FROM  dba_profiles；
select  *  from  dba_users;
select  username, user_id, account_status, expiry_date, profile  from  dba_users;

---后期修改数据库时区-（先改系统时区）
select dbtimezone,systimestamp from dual;
+08:00
29-JUL-19 09.40.03.769147 AM +08:00

select sysdate from dual;

alter database set time_zone='+8:00';
--grid 用户
srvctl stop database -d msrkzyk  
srvctl start database -d msrkzyk


--aix ntp
startsrc -s xntpd
stopsrc -s xntpd

lssrc -ls xntpd
xntpdc -c peers

---------------------------------------------------------------------
acfs 更换挂载点
root 下
1、取消两个节点的挂载
umount /挂载目录
2、取消acfs文件的注册
acfsutil registry -d /u01
3、删除acfs系统
acfsutil rmfs /dev/asm/asm_pic
4、查看asm volume 信息
su - grid
asmcmd
 volinfo -G ACF -a
5、禁用asm volume

voldisable -G ACFS ACFS  -- 前一个是disgroup name 后一个acfs是volume name
volinfo  -G ACFS -a
6、删除asm volume
voldelete -G ACFS ACFS
volinfo  -G ACFS -a


-------------------------------------------------------------
定时调动执行不起
SQL> alter system set job_queue_processes=1000;

System altered.

SQL> show parameter queue_processes

rman 修改备份文件路径并备份
alter system set events '10298 trace name context forever,level 32';
configure channel 1 device type disk format '/data/%d_db_%u.dmp';
configure channel 2 device type disk format '/data/%d_db_%u.dmp';
backup database plus archivelog delete input;


create script full_backup {
allocate channel c1 device type disk format '/data/%d_db1_%u.dmp';

backup database;
release channel c1;
release channel c1;
}

run {
allocate channel c1 device type disk format '/data/%d_db1_%u.dmp';
allocate channel c2 device type disk format '/data/%d_db2_%u.dmp';
backup database;
release channel c1;
release channel c1;
