CentOS6u9 Oracle11g RAC 搭建部署（八）OGG测试

数据库 2018-06-13 05:07:17 阅读次数: 3

简单说明：

依据《CentOS6u9 Oracle 11g 静默安装手工建库统一配置方案》
和《CentOS6u9 Oracle11g 内存策略选择和大页内存优化》
以及《CentOS6u9 Oracle11g 单机OGG灾备部署测试》
搭建11g单机OGG灾备环境，只做OGG的预部署部分

相应统计信息如下：
    A端：11g单机，IP 192.168.77.100，SID orcl，字符集 utf8，测试账号 test1
    B端：11g RAC，IP 192.168.77.11 ，SID orcl，字符集 utf8，测试账号 test2

实验设计：
    实验1：配置11g单机到11g RAC的测试账号test1的灾备同步
    实验2：配置11g RAC到11g单机的测试账号test2的灾备同步

实验1：

1° A端创建测试账号test1，模拟生产

su - oracle
# 创建测试用业务账号，赋权，创建测试sequence和测试table
sqlplus / as sysdba
create user test1 identified by test1 default tablespace users;
grant connect,resource to test1;
grant select on v_$session to test1;
grant select on v_$sesstat to test1;
grant select on v_$statname to test1;
grant execute on sys.dbms_lock TO test1;
conn test1/test1
create table test1(id number);
create sequence seq_test1
minvalue 1
maxvalue 999999999999999999999999999
start with 1
increment by 1
cache 20;
exit
# 创建脚本，并行执行，模拟生产
cat >/tmp/test1.sh<<EOFALL
sqlplus -s test1/test1<<EOF
begin
  for i in 1..100000 loop
    insert into test1 values(seq_test1.nextval);
    commit;
    dbms_lock.sleep(1);
  end loop;
end;
/
EOF
EOFALL
for i in $(seq 10);do bash /tmp/test1.sh & done

2° A端配置，创建配置抽取进程：

su - oracle
# 创建目录，将抽取同步数据放在自己专有的目录内
mkdir /ggs/dirdat_test1
# 创建抽取进程配置文件
cd /ggs/dirprm
cat >exttest1.prm<<EOF
EXTRACT exttest1
setenv (ORACLE_SID=orcl)
setenv (NLS_LANG=AMERICAN_AMERICA.UTF8)
SETENV (ORACLE_HOME = "/u01/app/oracle/product/11.2.0/db_1")

ddloptions addtrandata,report
-- 只抽取业务账号的DDL，动态添加trandata
reportrollover at 02:00
discardfile ./dirrpt/exttest1.dsc,append,megabytes 10
gettruncates
numfiles 3000
EXTTRAIL ./dirdat_test1/et

EOF
# 配置启动抽取进程
cd /ggs

info trandata test1.*
add extract exttest1,tranlog,begin now
add exttrail ./dirdat_test1/et, extract exttest1
start exttest1
info exttest1
exit

3° A端配置，创建配置发送进程：

su - oracle
# 在B端创建对应的目录，配置发送进程时会将文件放入该目录中
ssh oracle@192.168.77.11 'mkdir /ggs/dirdat_test1'
cd /ggs/dirprm
cat >puptest1.prm<<EOF

---sequence
sequence test1.*;
EOF
# 配置启动发送进程
# 确认目标端mgr进程已启动
ssh oracle@192.168.77.11 'netstat -tupln|grep 8000'
cd /ggs
./ggsci
add extract puptest1,exttrailsource ./dirdat_test1/et
add rmttrail ./dirdat_test1/rt,extract puptest1
start puptest1
info puptest1
exit
# 确认目标端接收到了文件
ssh oracle@192.168.77.11 'ls -l /ggs/dirdat_test1/rt*'

4° A端配置，配置directory，数据泵导出测试账号test1，发送到B端：

su - oracle
mkdir /home/oracle/dmp
sqlplus / as sysdba
create directory dmp as '/home/oracle/dmp';
exit
# 查询出当前的SCN，建议在业务低峰时期进行数据同步操作
CUR_SCN=$(echo 'select to_char(current_scn) from v$database;'|sqlplus -s / as sysdba|grep '[0-9]')
# 数据泵导出，根据SCN导出
expdp \'/ as sysdba\' directory=dmp dumpfile=test1.dmp schemas=test1 FLASHBACK_SCN=${CUR_SCN}
scp /home/oracle/dmp/test1.dmp oracle@192.168.77.11:/tmp/

5° B端配置，配置directory，数据泵导入测试业务账号，禁用外键等：

su - oracle
mkdir /home/oracle/dmp 
sqlplus / as sysdba
create directory dmp as '/home/oracle/dmp';
exit
cp /tmp/test1.dmp /home/oracle/dmp
impdp \'/ as sysdba\' directory=dmp dumpfile=test1.dmp

# 跑脚本，禁用外键、触发器等对象
# 参见《CentOS6u9 Oracle11g 单机OGG灾备部署测试》

6° B端配置，创建配置应用进程：

su - oracle
# 创建应用进程配置文件
cd /ggs/dirprm
