19c单实例配置GoldenGate 并进行用户数据同步测试

当前数据使用的是经典模式配置GoldenGate 进行数据同步,关于容器数据库配置GoldenGate 请参阅:

Configuring Oracle GoldenGate in a Multitenant Container Database (Doc ID 2031069.1)

一、数据库操作

1、开启数据库附加日志

开启的最小附加日志和强制日志

SQL> alter database add supplemental log data;
SQL> select supplemental_log_data_min from v$database;
SQL> alter database force logging;
SQL> select force_logging from v$database;

2、开启数据库归档模式

RAC所有节点
SQL> shutdown immediate

实例1:
SQL> startup mount
SQL> alter database archivelog;
SQL> archive log list;
SQL> alter database open;

实例2 :
直接执行
SQL> startup

如果需要修改归档日志路径:

SQL> alter system set log_archive_dest_1= 'location=<归档路径>' sid='*';

3、开启goldengate同步

SQL> show parameter gol

NAME				     				TYPE	 VALUE
------------------------------------ ----------- ------------------------------
enable_goldengate_replication	     boolean	 FALSE


SQL> alter system set ENABLE_GOLDENGATE_REPLICATION=true;

System altered.


SQL> show parameter gol

NAME				     				TYPE	 VALUE
------------------------------------ ----------- ------------------------------
enable_goldengate_replication	     boolean	 TRUE

4、创建goldengate管理用户

--1、create tablespace
create tablespace gguser_dat datafile '/u01/app/oracle/oradata/ORCL/gguser_dat_01.dbf' size 100m autoextend on next 100m maxsize unlimited;

--2、create the user 
create user gguser IDENTIFIED BY gguser123
  default tablespace gguser_dat
  temporary tablespace TEMP
  profile DEFAULT;

--3、Grant role privileges 
grant connect to GGUSER;
grant resource to GGUSER;

--4、Grant system privileges 
grant alter any index to GGUSER;
grant alter any table to GGUSER;
grant alter session to GGUSER;
grant alter system to GGUSER;
grant create any directory to GGUSER;
grant create any index to GGUSER;
grant create any table to GGUSER;
grant create session to GGUSER;
grant delete any table to GGUSER;
grant drop any directory to GGUSER;
grant drop any index to GGUSER;
grant drop any table to GGUSER;
grant flashback any table to GGUSER;
grant insert any table to GGUSER;
grant select any dictionary to GGUSER;
grant select any table to GGUSER;
grant select any transaction to GGUSER;
grant unlimited tablespace to GGUSER;
grant update any table to GGUSER;

5、集成捕获所需权限授权

授予gguser用户集成捕获所需的权限

SQL> exec dbms_goldengate_auth.grant_admin_privilege('GGUSER',container=>'ALL');

请参阅:Integrated Capture Process Cannot Start with OGG-02061 at Multitenant Configuration (Doc ID 2748951.1)

6、创建测试用户及测试表

--1、创建测试用户表空间(SHUAIGE_DAT)
create tablespace shuaige_dat datafile '/u01/app/oracle/oradata/ORCL/shuaige_dat_01.dbf' size 100M autoextend on next 100m maxsize unlimited;

--2、创建测试用户(SHUAIGE),密码(shuaige123)
create user SHUAIGE IDENTIFIED BY shuaige123
  default tablespace shuaige_dat
  temporary tablespace TEMP
  quota unlimited ON shuaige_dat
  profile DEFAULT;

--3、授予用户(SHUAIGE)用户数据库角色
grant connect to SHUAIGE;
grant resource to SHUAIGE;

--4、创建测试表

--测试表(T1)
CREATE TABLE SHUAIGE.T1 (
    ID number(10),
    NAME varchar2(30))
    tablespace shuaige_dat;

--测试表(T2)
CREATE TABLE SHUAIGE.T2 (
    ID number(10),
    NAME varchar2(30))
    tablespace shuaige_dat;

--5、给测试表创建主键约束

--创建表主键(T1),主键名(T1_PK),主键列(ID)
alter table SHUAIGE.T1 add constraint T1_PK primary key(id)
using index
tablespace shuaige_dat;

--创建表主键(T2),主键名(T2_PK),主键列(ID)
alter table SHUAIGE.T2 add constraint T2_PK primary key(id)
using index
tablespace shuaige_dat;

测试目标即(SHUAIGE.T1)表数据使用Goldengate同步到(SHUAIGE.T2)表

二、配置GOLDENGATE

1、配置MGR

GGSCI > edit params mgr

添加以下内容:

PORT 7809

DYNAMICPORTLIST 7810-7899

USERID gguser, PASSWORD AACAAAAAAAAAAAJAACQGHDZHDDGFMEACUCUEPFYGGJBFJGIH BLOWFISH, ENCRYPTKEY DEFAULT

AUTORESTART ER *, RETRIES 5, WAITMINUTES 1, RESETMINUTES 10

PURGEOLDEXTRACTS ./dirdat/*, USECHECKPOINTS, MINKEEPDAYS 1

LAGINFOMINUTES 10
LAGCRITICALMINUTES 60

使用goldengate默认生成的key的加密方法:encrypt password <要进行加密的密码>,ENCRYPTKEY default Using default key

示例:(用户:gguser,密码:gguser123),对该密码进行加密

GGSCI  27> encrypt password gguser123,ENCRYPTKEY default Using default key
Using Blowfish encryption with DEFAULT key.
Encrypted password:  AACAAAAAAAAAAAJAACQGHDZHDDGFMEACUCUEPFYGGJBFJGIH
Algorithm used:  BLOWFISH

为了安全起见最好在goldengate配置文件中使用加密密码进行配置,当然明文密码也是可用的

2、重启MGR

GGSCI > stop mgr
Manager process is required by other GGS processes.
Are you sure you want to stop it (y/n)?y

Sending STOP request to MANAGER ...
Request processed.
Manager stopped.


GGSCI > start mgr
Manager started.

3、配置GLOBALS

GGSCI > edit params ./GLOBALS

添加以下内容:

CHECKPOINTTABLE gguser.checkpoint
OUTPUTFILEUMASK 027

4、创建checkpoint表

GGSCI > DBLOGIN USERID gguser, PASSWORD AACAAAAAAAAAAAJAACQGHDZHDDGFMEACUCUEPFYGGJBFJGIH BLOWFISH, ENCRYPTKEY DEFAULT

Successfully logged into database.

GGSCI > ADD CHECKPOINTTABLE gguser.checkpoint

Successfully created checkpoint table gguser.checkpoint.

或使用明文密码登录数据库:dblogin userid , password ,示例如下:

GGSCI > dblogin userid gguser, password gguser123
Successfully logged into database.

5、添加表级别的附加日志

ggsci命令行中登录数据库

GGSCI > DBLOGIN USERID gguser, PASSWORD AACAAAAAAAAAAAJAACQGHDZHDDGFMEACUCUEPFYGGJBFJGIH BLOWFISH, ENCRYPTKEY DEFAULT

Successfully logged into database.
  1. 若数据全部同步没有条件、没有主键表、添加表级别附加日志
    GGSCI > add trandata 用户名.表名
    
  2. 若数据同步有条件过滤并且表有主键,添加表级别附加日志
    GGSCI > add trandata 用户名.表名,clos(列名)
    

info trandata 用户.表名查询trandata是否添加成功(enable),未添加trandata为(disable)状态

按用户生成添加、查询、删除表级别附加日志sql,示例:

#在数据库中执行:
select 'add trandata '||owner||'.'||table_name from dba_tables where owner = 'SHUAIGE';
select 'info trandata '||owner||'.'||table_name from dba_tables where owner = 'SHUAIGE';
select 'delete trandata '||owner||'.'||table_name from dba_tables where owner = 'SHUAIGE';
#在GGSCI中执行:
add trandata SHUAIGE.T1
add trandata SHUAIGE.T2

info trandata SHUAIGE.T1
info trandata SHUAIGE.T2

添加成功输出如下:

GGSCI > add trandata SHUAIGE.T1

2022-05-10 10:41:10  INFO    OGG-15132  Logging of supplemental redo data enabled for table SHUAIGE.T1.

2022-05-10 10:41:10  INFO    OGG-15133  TRANDATA for scheduling columns has been added on table SHUAIGE.T1.

Oracle Goldengate marked following column as key columns on table SHUAIGE.T2: ID.

校验trandata输出如下:

GGSCI > info trandata SHUAIGE.T1

2022-05-10 10:43:26  INFO    OGG-10471  ***** Oracle Goldengate support information on table SHUAIGE.T1 *****

Prepared CSN for table SHUAIGE.T1: 2175964

GGSCI > info trandata SHUAIGE.T2

2022-05-10 10:43:33  INFO    OGG-10471  ***** Oracle Goldengate support information on table SHUAIGE.T2 *****

Prepared CSN for table SHUAIGE.T2: 2176044
GGSCI (ocp19c as gguser@orcl) 14>

6、查询数据库字符集

当前数据库session的环境字符集:

SQL> select userenv('language') from dual;

AMERICAN_AMERICA.AL32UTF8

7、添加抽取进程

GGSCI > add extract ef_test1,TRANLOG,BEGIN NOW

GGSCI > add exttrail ./dirdat/cs,extract ef_test1

GGSCI > edit params ef_test1

(./dirdat/cs)表示extract进程生成exttrail文件的位置和文件名开头为cs,示例文件:

-rw-r----- 1 ggate ggate 1823 May 10 11:24 cs000000000

goldengate所有的进程(extract、replicat)的名字都不能超过八个字符,在添加进程和设置配置文件的时候最好起一些有含义的名字

这个示例(ef_test1)ef代表捕获进程也叫抽取进程,test1就代表第一个测试

添加以下内容:

EXTRACT ef_test1

SETENV (ORACLE_SID="orcl")
SETENV(NLS_LANG="AMERICAN_AMERICA.AL32UTF8")

USERID gguser, PASSWORD AACAAAAAAAAAAAJAACQGHDZHDDGFMEACUCUEPFYGGJBFJGIH BLOWFISH, ENCRYPTKEY DEFAULT

NUMFILES 3000
EOFDELAYCSECS 10

EXTTRAIL ./dirdat/cs

TRANLOGOPTIONS LOGRETENTION DISABLED
TRANLOGOPTIONS DBLOGREADER
TRANLOGOPTIONS DBLOGREADERBUFSIZE 1048576
TRANLOGOPTIONS _NOREADAHEAD ANY

WARNLONGTRANS 4H, CHECKINTERVAL 300

GETTRUNCATES
GETUPDATEBEFORES

NOCOMPRESSDELETES

CACHEMGR, CACHESIZE 128MB

-- TABLES
TABLE shuaige.t1;

注意:进程中所有的参数都可以按照实际的生产或测试需求添加,以上参数是我比较常用的

我发现在19c 配置goldengate与11g配置goldengate不同的地方和个别参数限制,如下:

  1. 不能在添加抽取进程时指定线程(thread)参数(单实例)
  2. value "3 M" is out of legal range (300 s - 20000000 s) for [checkinterval].
  3. CACHESIZE. Range values between: min 128 - max 2097152 MB.

在GGSCI命令行输入help查询更多帮助信息

8、添加复制进程

GGSCI > add replicat rf_test1,exttrail ./dirdat/cs, checkpointtable gguser.checkpoint

GGSCI > edit params rf_test1

这里的(./dirdat/cs)表示要指定replicat进程读取的exttrail文件

在(3、配置GLOBALS)中已经配置了全局GLOBALS,添加复制进程时会自动添加到gguser.checkpoint,若添加时手动指定checkpoint表,则以手动指定的为准

添加以下内容:

REPLICAT rf_test1

SETENV(NLS_LANG="AMERICAN_AMERICA.AL32UTF8")

USERID gguser, PASSWORD AACAAAAAAAAAAAJAACQGHDZHDDGFMEACUCUEPFYGGJBFJGIH BLOWFISH, ENCRYPTKEY DEFAULT

SQLEXEC "ALTER SESSION SET COMMIT_LOGGING=IMMEDIATE"
SQLEXEC "ALTER SESSION SET COMMIT_WAIT=NOWAIT"

NUMFILES 3000
EOFDELAYCSECS 10

DISCARDFILE ./dirdsc/rf_test1.dsc, APPEND, MEGABYTES 512
DISCARDROLLOVER AT 00:00

ASSUMETARGETDEFS

ALLOWNOOPUPDATES

GETTRUNCATES
GETUPDATEBEFORES

--TABLES
MAP shuaige.t1, TARGET shuaige.t2;

注意:进程中所有的参数都可以按照实际的生产或测试需求添加,以上参数是我比较常用的

这个示例(rf_test1)rf代表复制进程也叫应用进程,所有rf_test1就代表第一个测试的复制进程

使用ggate用户手动创建dirdsc目录,因为我在这个复制进程中配置了DISCARDFILE参数,会在指定目录下生成.dsc文件

mkdir -p /ggate/dirdsc

9、启动抽取进程与复制进程

GGSCI > start ef_test1
GGSCI > start rf_test1

查看进程状态

GGSCI > info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

MANAGER     RUNNING                                           
EXTRACT     RUNNING     EF_TEST1    00:00:00      00:00:06    
REPLICAT    RUNNING     RF_TEST1    00:00:00      00:00:07

三、进行数据同步测试:

1、数据插入测试

(1)向SHUAIGE.T1表中插入一条数据
SYS@orcl> insert into shuaige.T1 values(1,'李清照');

1 row created.

SYS@orcl> commit;

Commit complete.
(2)检查进程同步状态
GGSCI >  stats ef_test1,total

Sending STATS request to EXTRACT EF_TEST1 ...

Start of Statistics at 2022-05-10 11:25:49.

Output to ./dirdat/cs:

Extracting from SHUAIGE.T1 to SHUAIGE.T1:

*** Total statistics since 2022-05-10 11:24:10 ***

	Total operations                	           1.00

End of Statistics.

可以看到插入的数据已经成功的捕获和应用了

常用检查进程状态命令stats,EXTRACT与REPLICAT进程都适用

GGSCI > stats EXTRACT,total --查看当前进程所有的操作状态

GGSCI > stats EXTRACT,hourly --查看当前小时整点到当前时间所有的操作状态

GGSCI > stats EXTRACT,daily --查看今日凌晨0点到当前时间所有的操作状态

详情查看(help stats EXTRACT)(help stats REPLICAT):

(3)验证数据是否同步
SYS@orcl> select * from shuaige.t1;

		ID NAME
---------- ------------------------------
         1 李清照

SYS@orcl> select * from shuaige.t2;

		ID NAME
---------- ------------------------------
         1 李清照

2、数据更新测试
