1 安装前的确认作业

1.1 CDC组件说明

CDC整体由以下几个组件构建:

(1)CDC实例引擎,简称IIDR,用于连接目标数据库进行数据捕获或数据落实的组件,可以安装在DB的本地或通过REMOTE(JDBC)的方式连接DB;

(2)Access Server,简称AS,用于连接及管理CDC引擎,配置完成后CDC引擎间会自行进行通讯,即使AS宕机也不影响CDC的正常复制;

(3)Management Console,简称MC,用于操作AS的UI工具,可以代替AS中的命令行操作。

1.2 安装包说明

CDC三个组件的安装包如下,一般建议CDC引擎及AS安装在单独的linux服务器上,MC自行安装在windows上,需要特别注意的是,AS与MC的版本必须保持一致,否则会导致组件间通讯异常的情况。

2 安装Access Server

2.1 用户及安装目录

不能使用root用户进行安装,故需要新建一个操作账号。

useradd cdcadmin

创建安装目录。

[root@localhost ~]# mkdir -p /opt/IBM/InfoSphereDataReplication/AccessServer
[root@localhost ~]# chown -R cdcadmin:cdcadmin /opt/IBM/InfoSphereDataReplication/AccessServer

2.2 准备安装包

拷贝安装包至本机,使用chmod +x 命令对安装赋予执行权限。

[root@localhost ~]# cd /home/softwares/
[root@localhost softwares]# ll
total 291924
-rwxr-xr-x. 1 root root 298927287 May 23 20:50 iidraccess-11.4.0.4-11086-linux-x86-setup.bin
[root@localhost softwares]# ls

[cdcadmin@localhost bin]$ ./dmlistusers
User Role Manager Disabled Locked PwdChange Expires
----------------- --------- ---------- --------- --------- --------- ---------
cdcadmin SYSADMIN true false false false false

3 安装IIDR(DB2)

3.1 安装DB2 Client

由于CDC引擎需要与DB2进行连接,故使用db2 client的方式添加远程DB2连接,在此,先要安装DB2 Client,至于DB2 Client的安装过程不在此规范中说明。

DB2 client的实例目录为:/db2data/inst01/userhome,实例及实例用户均为inst01。

3.2 规划CDC引擎的安装目录

与DB2实例主目录一致(建议),CDC引擎建立在db2 client实例目录内,故新建以下两个CDC目录:

  • 安装目录:/db2data/inst01/cdchome
  • 刷新目录:/db2data/inst10/cdcfresh 

上述两目录使用chown命令赋予db2 client实例用户权限:

[root@localhost inst01]# chown inst01:db2iadm cdchome/
[root@localhost inst01]# chown inst01:db2iadm cdcfresh/
[root@localhost inst01]# ls -l
total 0
drwxr-xr-x. 2 inst01 db2iadm 6 May 24 19:31 cdcfresh
drwxr-xr-x. 2 inst01 db2iadm 6 May 24 19:31 cdchome
drwx------. 2 fenc01 db2fadm 62 May 24 19:25 fenchome
drwxr-xr-x. 7 inst01 db2iadm 168 May 24 19:31 userhome

3.3 执行安装

使用root用户对cdc引擎的安装文件赋予可执行权限。

[root@localhost softwares]# chmod +x setup-iidr-11.4.0.4-5629-linux-x86.bin 
[root@localhost softwares]# ll
total 983080
drwxr-xr-x. 3 root root 166 May 24 19:22 client
-rwxr-xr-x. 1 root root 369709193 May 24 19:34 setup-iidr-11.4.0.4-5629-linux-x86.bin
-rw-r--r--. 1 root root 636958085 May 24 18:57 v11.5.5fp1_linuxx64_client.tar.gz

切换db2实例用户(也即是cdc引擎的用户),执行安装命令:

[root@localhost softwares]# su inst01
[inst01@localhost softwares]$ ./setup-iidr-11.4.0.4-5629-linux-x86.bin

至此,CDC引擎的安装已经完成。

4 安装Management Console

MC的安装是在windows下使用图形安装的,没有技术含量,只需要确认MC的版本与AS的版本保持一致。

安装完成后可以尝试登录 AS,前提是要确认以下几点:

  • AS已经正常启动;
  • AS已经建立了管理员账号、密码;
  • AS服务器防火墙已经放开了相关的端口;

【IBM CDC系列】CDC的安装_ibm_03

5 建立CDC复制

以下内容将说明如何正确使用CDC的工具配置两个数据库的同步,在此以两个测试DB进行举例说明,两个测试数据库的连接信息如下:

DB1(源)

DB2(目标)

数据库名:sample

IP:192.168.194.129

端口:50100

账号/密码:inst01/***

其他:开启归档日志,只有开启归档日志才可以当作数据源

数据库名:sample

IP:192.168.194.129

端口:50200

账号/密码:inst02/***

其他:开启归档日志,只有开启归档日志才可以当作数据源

上述DB事实上同名的,注意在catalog时使用正确的别名。

5.1 编目数据库连接

编目数据库是在CDC引擎的服务器进行,使用db2 client对两个数据库进行编目,使用以下命令:

[root@localhost softwares]# su - inst01
Last login: Tue May 24 19:34:38 PDT 2022 on pts/1
[inst01@localhost ~]$ db2 catalog tcpip node db2node1 remote 192.168.194.129 server 50100
DB20000I The CATALOG TCPIP NODE command completed successfully.
DB21056W Directory changes may not be effective until the directory cache is
refreshed.
[inst01@localhost ~]$ db2 catalog tcpip node db2node2 remote 192.168.194.129 server 50200
DB20000I The CATALOG TCPIP NODE command completed successfully.
DB21056W Directory changes may not be effective until the directory cache is
refreshed.
[inst01@localhost ~]$ db2 catalog db sample as sampl1 at node db2node1
DB20000I The CATALOG DATABASE command completed successfully.
DB21056W Directory changes may not be effective until the directory cache is
refreshed.
[inst01@localhost ~]$ db2 catalog db sample as sampl2 at node db2node2
DB20000I The CATALOG DATABASE command completed successfully.
DB21056W Directory changes may not be effective until the directory cache is
refreshed.
[inst01@localhost ~]$ db2 list db directory

System Database Directory

Number of entries in the directory = 2

Database 1 entry:

Database alias = SAMPL1
Database name = SAMPLE
Node name = DB2NODE1
Database release level = 15.00
Comment =
Directory entry type = Remote
Catalog database partition number = -1
Alternate server hostname =
Alternate server port number =

Database 2 entry:

Database alias = SAMPL2
Database name = SAMPLE
Node name = DB2NODE2
Database release level = 15.00
Comment =
Directory entry type = Remote
Catalog database partition number = -1
Alternate server hostname =
Alternate server port number =

编目完成,需要使用db2 client对remote的数据库进行连接测试,如果连接成功后可以继续进行下一步。

5.2 创建CDC实例

给每一个CDC实例建立自己独立的刷新目录是一个良好的习惯,故提前建立以下实例的刷新目录:

  • /db2data/cdcfresh/T_SAMPL1
  • /db2data/cdcfresh/T_SAMPL2

并确认目录的owner的cdc引擎的安装用户(也是db2 client的安装用户)

进行<cdchome>/bin目录下,执行./ dmconfiguretsCDC命令,开始创建一个新的CDC实例,输入CDC实例的名~称,再回车下一步:

CONFIGURATION TOOL - CREATING A NEW INSTANCE

--------------------------------------------


Enter the name of the new instance: T_SAMPL1

CONFIGURATION TOOL - CREATING A NEW INSTANCE

--------------------------------------------


Enter the name of the new instance: T_SAMPL1

CONFIGURATION  TOOL - CREATING A NEW INSTANCE
--------------------------------------------

Enter the name of the new instance: T_SAMPL1

每CDC实例需要端口号,可按规划的端口名称进行修改:

Enter the server port number [10901]:

对CDC实例的磁盘空间进行限制,依据磁盘需要进行设置:

Staging Store Disk Quota is used to limit the disk space used by IBM InfoSphere Data Replication staging Store. If this space is exhausted, this instance may run at a lower speed. The minimum value allowed is 1 GB. 

Enter the Staging Store Disk Quota for this instance (GB) [100]: 2

对CDC实例占用的内存进行限制,依据系统情况进行设置,但如果在多个CDC实例导致系统总体的内存不足时,CDC的实例会容易崩溃:

Enter the Maximum Memory Allowed for this instance (MB) [1024]: 512

此时会提示加密配置文件,这项内容在CDC v11版本时是不存在的,暂时也不知道详细用途,但又必须存在,建议配置一个名为DEFAULT的不启用的文件,以下内容均为对此文件配置的内容,配置完成后再回到cdc实例创建的过程。

​以下选择1,创建一个新的加密配置文件:

Encryption profile:

1. Manage encryption profiles

Select an encryption profile: 1

选择新建:

MANAGE ENCRYPTION PROFILES
--------------------------

1. Add encryption profile
2. Edit encryption profile
3. Delete encryption profile

4. Completed management of encryption profiles

Enter your selection:1

设置名称为DEFAULT:

Enter an encryption profile name: DEFAULT

关闭加密,选择2:

Engine-to-engine encryption enablement:

1. Enabled
2. Disabled
3. Required
4. Always

Select the engine-to-engine encryption enablement [Enabled]: 2

默认回车:

Enter the path to the private key store or press ENTER for no private key store :

默认回车:

Enter the path to the trust store [/db2data/inst01/cdchome/jre64/jre/lib/security/cacerts]:

默认回车:

Enter the password that was used to encrypt the trust store or press ENTER to keep the same password:

默认回车:

Trust store type:

1. JKS (Java)
2. JCEKS (Java Cryptography Extension)
3. PKCS12 (Public-Key Cryptography Standards)

Select the trust store type [JKS (Java)]:

完成配置,选择4退出对加密文件的配置:

MANAGE ENCRYPTION PROFILES
--------------------------

1. Add encryption profile
2. Edit encryption profile
3. Delete encryption profile

4. Completed management of encryption profiles

Enter your selection:4

此时可以选择刚刚配置的加密文件,进行下一步:

Encryption profile:

1. DEFAULT
2. Manage encryption profiles

Select an encryption profile: 1

默认回车:

Select y to use JMS or TCP/IP engine communication connection, select n to use TCP only engine communication connection (y/n) [n]:

默认回车:

Do you wish to establish a JDBC type 4 connection to the database? [n]:

选择sampl1所在的实例,这里只能选择inst01:

Select a DB2 Instance

1. inst01
2. Other...

Select a DB2 Instance [inst01]:

如果没有列出实例里的DB名称,则选择Other,如下:

Select a database name

1. Other...

Select a database name: 1

提示输入数据库的名称,如下:

Enter the database name: SAMPL1

此处如果不了解所谓的高级参数,则选择n:

Would you like to configure advanced parameters (y/n) [y]: n

默认回车:

Would you like to retrieve database login credentials from an external secret store through a Java user exit? (y/n) [n]:

输出目标数据库的账号,此处为inst01。

Enter the username: inst01

输出对应的密码:

Enter the password:

建立CDC专用的metadata的schema,此处选择3:

Retrieving schema list...
Metadata schema:

1. INST01
2. TPCC
3. Other...

Select a database schema for metadata tables: 3

CDC专用的schema的名称使用“CDC“:

Enter a database schema for metadata tables: CDC

询问是否建立loader path,选择y:

Would you like to specify a refresh loader path (y/n) [y]:

输入之前建好refresh的目录,注意目录的权限:

Enter the refresh loader path: /db2data/inst01/cdcfresh/T_SAMPL1

创建完成,此时可以尝试启动CDC实例:

Creating a new instance. Please wait...


Instance T_SAMPL1 was successfully created.

Would you like to START instance T_SAMPL1 now (y/n)?y

启动完成可,cdc会回退至主菜单:

MAIN MENU
---------

1. List Current Instances
2. Add an Instance
3. Edit an Instance
4. Delete an Instance
5. Consolidate Instances
6. Manage encryption profiles

7. Exit

Enter your selection:1

选择1可以查看当前的已经运行的CDC引擎:

LIST OF CURRENT INSTANCES
-------------------------

Name Server Port Database Schema Status
--------- ----------- ------------- ----------- ------------
T_SAMPL1 10901 SAMPL1 CDC running


Press ENTER to return to the Main menu...

按照上述的步骤使用./dmconfigurets配置第二个CDC实例:T_SAMPL2,最后完成的CDC实例如下:

LIST OF CURRENT INSTANCES
-------------------------

Name Server Port Database Schema Status
--------- ----------- ------------- ----------- ------------
T_SAMPL1 10901 SAMPL1 CDC running
T_SAMPL2 10902 SAMPL2 CDC running


Press ENTER to return to the Main menu...

5.3 添加数据存储器

数据存储器,可以理解为CDC实例,以下操作均使用MC进行图形化作业,在上述章节已经创建了两个CDC实例,信息如下:

T_SAMPL1(源)

T_SAMPL2(目标)

名称:T_SAMPL1

IP:192.168.194.131

端口:10901

名称:T_SAMPL2

IP:192.168.194.131

端口:10902

登录MC,在Access Manager面板,右键选择“新建数据存储器“,填入相对应的CDC实例信息(如下图),选择”ping“按钮可以检测到CDC实例的相关信息,在下图的”连接参数“输入数据库的账号密码(此文档inst01是为多个项目的用户,请注意不要混淆)。

【IBM CDC系列】CDC的安装_数据库_04

添加完成如下图,再给每个数据库存储器分配指定的用户,如下图,只有分配用户才能进行预定的管理。

【IBM CDC系列】CDC的安装_数据库_05

5.4 新建CDC预订

完成数据存储器的配置,在MC中的“配置面板“,选择新建预订,赶往预订的名称,选择好指定的源与目标,再确定。

【IBM CDC系列】CDC的安装_IIDR_06

建好预订后,在“表映射“面板选择”映射表“,按提示选择要复制的表:

【IBM CDC系列】CDC的安装_数据库_07

映射完表后,可以直接开启刷新或镜像复制。

5.5 CDC系统参数配置

上述表映射后,如果直接开始镜像复制的话,目标将会报Fastload的错误,因为CDC默认CDC引擎是安装在DB的本地的,而通过JDBC远程连接,CDC的load命令会有问题,需要针对每个CDC的数据存储器添加以下系统参数:use_jdbc_for_refresh = true,如下图:

【IBM CDC系列】CDC的安装_ibm_08

**注意:参数配置完成后,需要重启CDC实例才能生效。

【完】写得好累~~
