dmhs oracle to dm8

环境准备

源端配置

数据库配置

安装oracle odbc包（需要安装gcc-c++）

oracle用户下安装dmhs：

目标端DM8配置

配置DMHS

源端oracle dmhs.hs

目标端dmhs.hs

启动dmhs服务

环境准备

源端：rhel8.5 + oracle 19C

目的端：rhel8.5 + dm8

源端配置
数据库配置

1、开启归档：SQL> shutdown immediateSQL> alter database archivelog;SQL> alter system set LOG_ARCHIVE_DEST_1='LOCATION=/Oradata/arch' scope=both;SQL> alter database open;2、创建用于同步的表空间 user 赋权等SQL> create tablespace data_test datafile 'data_test.dbf' size 1G autoextend off;SQL> create user ora_test identified by "Dameng88" default tablespace data_test;SQL> grant dba to ora_test;3、创建表、索引，并插入数据：create table ora_test.test1(C1 int not null,C2 varchar2(40))tablespace data_testpctused 0pctfree 10;create unique index ora_test.idx_test1_c1 on ora_test.test1(C1);-- tablespace DATA_TEST;ALTER TABLE ORA_TEST.TEST1ADD CONSTRAINT TEST1_PKPRIMARY KEY(C1) using index ora_test.idx_test1_c1;insert into ora_test.test1 values(1,'test0311');commit;4、
--检查数据库最小附加日志及全列日志：SQL> select SUPPLEMENTAL_LOG_DATA_MIN, SUPPLEMENTAL_LOG_DATA_ALL from v$database;--开启最小附加日志和全列日志SQL> alter database add supplemental log data;SQL> alter database add supplemental log data(all) columns;修改回收站参数：重新连接生效
SQL> show parameter recyclebin
SQL> alter system set recyclebin=off deferred;设置参数 允许DDL触发器的触发动作：
SQL> show parameter "_system_trig_enabled";
SQL> alter system set "_system_trig_enabled"=true scope=both;现实环境如果没有DBA权限，需要做如下赋权操作（例如用户是ora_test）：
grant all on dmhs_ddl_sql to ora_test;
grant select any table to ora_test;
grant select any dictionary to ora_test;--dba权限的用户也需要执行加粗部分
grant create session to ora_test;
grant lock any table to ora_test;
grant execute on dbms_flashback to ora_test;
grant flashback any table to ora_test;

配置tnsnames.ora

vim /oracle/19300/db_1/home/network/admin/tnsnames.ora

TESTORA =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.183.140)(PORT = 1526))

(CONNECT_DATA =

(SERVER = DEDICATED)

(SERVICE_NAME = testOra)

(INSTANCE_NAME = testOra)

)

安装oracle odbc包（需要安装gcc-c++）

上传unixODBC-2.3.9.tar.gz安装包（建议2.3版本以上）

[root@test1 ~]# cd /soft/
[root@test1 soft]# tar -xvf unixODBC-2.3.9.tar.gz
[root@test1 soft]# cd unixODBC-2.3.9/
[root@test1 unixODBC-2.3.9]# ./configure --prefix=/usr/local/unixODBC-2.3.9 --includedir=/usr/include --libdir=/usr/lib --bindir=/usr/bin --sysconfdir=/etc
[root@test1 unixODBC-2.3.9]# make &make install

isql oracle system Dameng88 oracle -v

报错：

[root@test1 soft]# odbcinst -j

odbcinst: error while loading shared libraries: libodbcinst.so.2: cannot open shared object file: No such file or directory

解决办法：执行ldconfig在默认目录/lib和/usr/lib搜寻可共享的动态链接库

oracle odbc连接报错

报错：[01000][unixODBC][Driver Manager]Can't open lib '/oracle/19300/db_1/home/lib/libsqora.so.19.1' : file not found

[ISQL]ERROR: Could not SQLConnect

[root@test1 ~]# isql oracle system Dameng88 oracle -v

[IM004][unixODBC][Driver Manager]Driver's SQLAllocHandle on SQL_HANDLE_HENV failed

[ISQL]ERROR: Could not SQLConnect

Segmentation fault (core dumped)

解决办法：

root用户下添加环境变量

[root@test1 ~]# vim ~/.bash_profile

export ORACLE_HOME=/oracle/19300/db_1/home

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME/srvm/lib:/lib:/usr/lib:/usr/openwin/lib:/usr/local/lib

[root@test1 ~]# source .bash_profile

报错：ORA-12154: TNS:could not resolve the connect identifier specified

解决办法：检查tns

oracle用户下安装dmhs：

先切换到root用户下授予权限

[root@test1 soft]# chmod +x dmhs_V4.1.48_oracle12_rev102088_rh6_64_veri_20210924.bin

切换到oracle用户下：

[root@test1 opt]# su - oracle

test1</home/oracle>$cd /soft/

test1</soft>$./dmhs_V4.1.48_oracle12_rev102088_rh6_64_veri_20210924.bin -i

源端创建表&触发器 sql脚本安装目录下scripts/ddl_sql_ora.sql

根据脚本创建表触发器等

目标端DM8配置

安装dm8数据库并配置服务开机自启

开启归档：
SQL> alter database mount;
SQL> alter database archivelog;
SQL> alter database add archivelog 'TYPE=LOCAL,DEST=/dmdata/DAMENG/arch,FILE_SIZE=1024,SPACE_LIMIT=10240';
SQL> alter database open;
--开启附加日志参数
SQL> alter system set 'RLOG_APPEND_LOGIC'=1 both;
.
安装dmhs创建表空间和用户：
create TABLESPACE data_test DATAFILE 'data_test_01.dbf' SIZE 1024 autoextend off;
create user u_test identified by "Dameng88." DEFAULT TABLESPACE DATA_TEST;

配置DMHS

源端oracle dmhs.hs

$vim /home/oracle/dmhs/bin/dmhs.hs

<?xml version="1.0" encoding="GB2312" standalone="no"?>

</dmhs>

目标端dmhs.hs

</dmhs>

启动dmhs服务

./dmhs_server dmhs.hs

源端：

目标端：

目标端新开一个连接

test</home/oracle/dmhs/bin>$./dmhs_console

DMHS> connect

DMHS> start exec

start exec 执行报错：

报错解决：

[root@test2 ~]# su - dmdba

[dmdba@test2 ~]$ cd dmhs/bin

[dmdba@test2 bin]$ ldd libdmhs_exec.so

[root@test2 ~]# find / -name libdmoci.so

[dmdba@test2 ~]$ vim ~/.bash_profile

添加：

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/dmdba/dmhs/bin:/home/dmdba/dmhs/db/bin

[dmdba@test2 ~]$ source ~/.bash_profile

重试：start exec 卡住

重新拷贝一个libdmoci.so到/home/dmdba/dmhs/bin下

重新start exec 报错

yum install -y unixODBC

依然执行start exec时卡住或报错

更换libdmoci.so文件（与目标数据库版本一致的so文件）：执行成功

源端开启一个连接

DMHS> connect

DMHS> clear exec lsn

报错：CSL[ERROR]: 初始装载失败

详细错误信息：

CPT[ERROR]: DB:ORA-12541: TNS:no listener

(code=12541)

CPT[ERROR]: OCI模块数据库登录失败，server=testOra; user=ora_test; password=******

解决：检查oracle数据库&监听是否开启，发现未开启数据库&监听，开启后重试

源端执行数据装载：

报错：初始装载失败

没有查询系统表和视图的权限：DB:ORA-01031: insufficient privileges

将权限赋予同步的账号查询系统基表的权限：

grant select on SYS.OBJ$ to ora_test;

grant select on sys.tab$ to ora_test;

grant select on SYS.USER$ to ora_test;

grant select on SYS.NTAB$ to ora_test;

grant select on sys.seg$ to ora_test;

源端开启同步：

DMHS> start

创建dmhs服务：

目标端dm

[root@test ~]# cd /home/dmdba/dmhs/scripts/root/

[root@test root]# ./dmhs_service_installer.sh -t dmhs_server -d /home/dmdba/dmhs/bin -p hs -x /home/dmdba/dmhs/bin/dmhs.hs

源端oracle：

[root@test1 ~]# cd /home/oracle/dmhs/scripts/root/

[root@test1 root]# ./dmhs_service_installer.sh -t dmhs_server -d /home/oracle/dmhs/bin -p hs -x /home/oracle/dmhs/bin/dmhs.hs
