KFS Oracle RAC 数据解析同步配置方法

、logminer方式解析

1、数据库配置 - Oracle

1. 数据库中需要先设置 NSL_DATE_FORMAT,命令如下,设置好以后需要重启数据库:

ALTER SYSTEM SET NLS_DATE_FORMAT='YYYY-MM-DD' SCOPE=SPFILE; --logmini模式必须

2. 创建 KFS用户并赋予相应的权限:

假设 KFS 用户为 FLYSYNC,如果能够提供 DBA 权限,那么该用户应该赋予的权限包括:

GRANT CONNECT, RESOURCE TO FLYSYNC;
GRANT EXECUTE_CATALOG_ROLE TO FLYSYNC;
GRANT CREATE SESSION TO FLYSYNC;
GRANT SELECT ANY TRANSACTION TO FLYSYNC;
GRANT SELECT ANY TABLE TO FLYSYNC;
GRANT UNLIMITED TABLESPACE TO FLYSYNC;
GRANT DBA TO FLYSYNC;

假设 Logminer 用户为 FLYSYNC,如果不能够提供 DBA 权限,可以赋予以下权限包括:

GRANT CONNECT TO FLYSYNC;
GRANT CREATE SESSION TO FLYSYNC;
GRANT UNLIMITED TABLESPACE TO FLYSYNC;
GRANT CREATE TABLE TO FLYSYNC;
GRANT CREATE MINING MODEL TO FLYSYNC;
GRANT LOGMINING TO FLYSYNC;
GRANT EXECUTE ON DBMS_FLASHBACK TO FLYSYNC;
GRANT EXECUTE ON DBMS_LOGMNR TO FLYSYNC;
GRANT EXECUTE ON DBMS_LOGMNR_D TO FLYSYNC;
GRANT EXECUTE ON SYS.DBMS_LOGMNR TO FLYSYNC;
GRANT EXECUTE ON SYS.DBMS_LOGMNR_D TO FLYSYNC;
GRANT EXECUTE ON SYS.DBMS_LOGMNR_INTERNAL TO FLYSYNC;
GRANT EXECUTE ON SYS.DBMS_LOGMNR_LOGREP_DICT TO FLYSYNC;
GRANT EXECUTE ON SYS.DBMS_LOGMNR_SESSION TO FLYSYNC;
GRANT EXECUTE_CATALOG_ROLE TO FLYSYNC;
GRANT SELECT ANY DICTIONARY TO FLYSYNC;
GRANT SELECT ANY TABLE TO FLYSYNC;
GRANT SELECT ANY TRANSACTION TO FLYSYNC;
GRANT SELECT ON SYS.V_$ARCHIVED_LOG TO FLYSYNC;
GRANT SELECT ON SYS.V_$DATABASE TO FLYSYNC;
GRANT SELECT ON SYS.V_$LOGMNR_CONTENTS TO FLYSYNC;
GRANT SELECT ON V_$ARCHIVED_LOG TO FLYSYNC;
GRANT SELECT ON V_$DATABASE TO FLYSYNC;
GRANT SELECT ON V_$LOG TO FLYSYNC;
GRANT SELECT ON V_$LOGFILE TO FLYSYNC;
GRANT SELECT ON V_$LOGMNR_CONTENTS TO FLYSYNC;
GRANT SELECT ON V_$LOGMNR_DICTIONARY TO FLYSYNC;
GRANT SELECT ON V_$LOGMNR_LOGS TO FLYSYNC;
GRANT SELECT ON V_$LOGMNR_PARAMETERS TO FLYSYNC;
GRANT SELECT ON V_$PARAMETER TO FLYSYNC;

备注说明:

• Oracle 12c 以上版本的数据库在创建用户时,有以下几种方式:

(1)、PDB数据库

CDB里创建用户,需要带c##前缀,如:C##FLYSYNC

PDB里创建用户,不用带C##前缀,如:FLYSYNC

(2)、非PDB数据库

不用带C##前缀,如:FLYSYNC

3. 安装 Logminer(如果没有安装 Logminer 需要在 sqlplus 中执行下面的语句(均需要用 sys 管理员执行))工具,命令如下(Oracle 10g、Oracle 11g 和 Oracle 12c):

@$ORACLE_HOME/RDBMS/ADMIN/dbmslm.sql
@$ORACLE_HOME/RDBMS/ADMIN/dbmslmd.sql
@$ORACLE_HOME/RDBMS/ADMIN/dbmslms.sql

注意:以上三个 SQL 脚本,如果在安装的 Oralce 数据库相应的目录中有则必须执行;如果没有则可忽略

4. 开启 Oracle 数据库的归档日志(必须开启)了,具体步骤如下:

• 检查是否归档已经开启

SQL> select log_mode from v$database;
LOG_MODE
------------
NOARCHIVELOG

• 开启归档(需要重启数据库)

(1)设置归档路径:

RAC的归档路径设置在共享磁盘内

SQL>alter system set log_archive_dest=’+DATA’ scope=spfile sid=’*’;

(2)然后关闭所有实例,启动1个实例,更改数据库为归档模式:

SQL>shutdown immediate;

SQL>startup mount;

SQL>alter database archivelog;

SQL>alter database open;

SQL>archive log list;

(3)启动其他节点,完成归档模式的变更过程。

SQL>startup;

在RAC环境下,归档路径的选择是值得斟酌的,如果使用共享的归档目录作为归档路径,则可以减少备份时的复杂性。如果使用独立的目录,则备份时需要进行特殊处理。

• 再次查看数据库归档情况

SQL> select log_mode from v$database;

LOG_MODE

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

ARCHIVELOG

5. 开启补全日志

• 检查补全日志的状态

SQL> SELECT supplemental_log_data_min, supplemental_log_data_pk, supplemental_log_data_all FROM v$database;

SUPPLEME SUP SUP
-------- --- ---
NO NO NO

• 开启补全日志 (建议在 MOUNT 模式下执行)

SQL> ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
Database altered.
SQL> ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (PRIMARY KEY) COLUMNS;
Database altered.
SQL> ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (ALL) COLUMNS;
Database altered.

• 再次检查补全日志的状态

SQL> SELECT supplemental_log_data_min, supplemental_log_data_pk,supplemental_log_data_all FROM v$database;

SUPPLEME SUP SUP
-------- --- ---
YES YES YES

6. 切换日志文件

SQL> ALTER SYSTEM SWITCH LOGFILE;

System altered

7. 若使用插接式数据库(pdb)

使用 sys 用户登录 sqlplus,查看所有 pdb 状态,并将使用的 pdb 开启, 例如 orclpdb

SQL> select con_id,dbid,name,open_mode from v$pdbs;

SQL> alter pluggable database orclpdb open;

2、flysync.ini配置

Flysync.ini这里需要添加集群的相关配置

[defaults]
install-directory=/home/flysync/kfsrep
profile-script=~/.bash_profile
rmi-port=11000

[oracle12rac]
role=master
master=rac1
members=rac1
kufl-port=3112
replication-host=192.168.100.103
replication-port=1521
replication-user=FLYSYNC
replication-password=123456
datasource-type=oracle
datasource-oracle-service=ORCL  #非PDB为SID名,PDB为PDB名称
oracle-extractor-method=logminer
svc-extractor-filters=dropstatementdata
property=replicator.extractor.dbms.tablePatterns=FLYSYNC.*,TEST.*
property=replicator.extractor.dbms.scnSegmentationThreshold=5000

#开启集群
property=replicator.datasource.global.connectionSpec.use_cluster=true

#集群其他节点IP,多个节点用逗号隔开
property=replicator.datasource.global.connectionSpec.slave_add=192.168.100.104

#集群其他节点端口,多个节点用逗号隔开
property=replicator.datasource.global.connectionSpec.slave_port=1521

 

二、redo方式解析

(一)数据库配置

1. 数据库中需要先设置 NSL_DATE_FORMAT,命令如下,设置好以后需要重启数据库:

ALTER SYSTEM SET NLS_DATE_FORMAT='YYYY-MM-DD' SCOPE=SPFILE; --logmini模式必须

2. 创建 KFS用户并赋予相应的权限:

假设 KFS用户为 FLYSYNC,如果能够提供 DBA 权限,那么该用户应该赋予的权限包括:

GRANT CONNECT, RESOURCE TO FLYSYNC;
GRANT EXECUTE_CATALOG_ROLE TO FLYSYNC;
GRANT CREATE SESSION TO FLYSYNC;
GRANT SELECT ANY TRANSACTION TO FLYSYNC;
GRANT SELECT ANY TABLE TO FLYSYNC;
GRANT UNLIMITED TABLESPACE TO FLYSYNC;
GRANT DBA TO FLYSYNC;

假设 kfs用户为 FLYSYNC,如果不能够提供 DBA 权限,可以赋予以下权限包括:
GRANT CONNECT TO FLYSYNC;
GRANT CREATE SESSION TO FLYSYNC;
GRANT UNLIMITED TABLESPACE TO FLYSYNC;
GRANT CREATE TABLE TO FLYSYNC;
GRANT EXECUTE_CATALOG_ROLE TO FLYSYNC;
GRANT SELECT ANY DICTIONARY TO FLYSYNC;
GRANT SELECT ON V_$PARAMETER TO FLYSYNC;

  

3. 开启 Oracle 数据库的归档日志(必须开启)了,具体步骤如下:

• 检查是否归档已经开启

SQL> select log_mode from v$database;

LOG_MODE

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

NOARCHIVELOG

• 开启归档(需要重启数据库)

(1)设置归档路径:

RAC的归档路径设置在共享磁盘内

SQL>alter system set log_archive_dest=’+DATA’ scope=spfile sid=’*';

(2)然后关闭所有实例,启动1个实例,更改数据库为归档模式:

SQL>shutdown immediate;
SQL>startup mount;
SQL>alter database archivelog;
SQL>alter database open;
SQL>archive log list;

(3)启动其他节点,完成归档模式的变更过程。

SQL>startup;

• 再次查看数据库归档情况

SQL> select log_mode from v$database;

------------
ARCHIVELOG

4. 开启补全日志

• 检查补全日志的状态

SQL> SELECT supplemental_log_data_min, supplemental_log_data_pk, supplemental_log_data_all FROM v$database;

SUPPLEME SUP SUP
-------- --- ---
NO NO NO

• 开启补全日志 (建议在 MOUNT 模式下执行)

SQL> ALTER DATABASE ADD SUPPLEMENTAL LOG DATA;
Database altered.
SQL> ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (PRIMARY KEY) COLUMNS;
Database altered.
SQL> ALTER DATABASE ADD SUPPLEMENTAL LOG DATA (ALL) COLUMNS;
Database altered.

• 再次检查补全日志的状态

SQL> SELECT supplemental_log_data_min, supplemental_log_data_pk, supplemental_log_data_all FROM v$database;

SUPPLEME SUP SUP
-------- --- ---
YES YES YES

5. 切换日志文件

SQL> ALTER SYSTEM SWITCH LOGFILE;

System altered

6. 若使用插接式数据库(pdb)

使用 sys 用户登录 sqlplus,查看所有 pdb 状态,并将使用的 pdb 开启, 例如 orclpdb

SQL> select con_id,dbid,name,open_mode from v$pdbs;

SQL> alter pluggable database orclpdb open;

 

(二)、flysync.ini配置

Redo模式的flysync.ini里不仅要配置集群相关参数,如果使用的是ASM存储,还需要配置ASM相关参数。

[defaults]
install-directory=/home/flysync/flysync_test
profile-script=~/.bash_profile
rmi-port=11000

[oracle11rac]
role=master
master=flysync-1
members=flysync-1
kufl-port=3112
replication-host=192.168.11.31
replication-port=1521
replication-user=TEST
replication-password=123456
datasource-type=oracle
datasource-oracle-service=RACDB2
oracle-extractor-method=redo
svc-extractor-filters=dropstatementdata
property=replicator.extractor.dbms.tablePatterns=TEST.*
property=replicator.extractor.dbms.scnSegmentationThreshold=5000

#开启集群
property=replicator.datasource.global.connectionSpec.use_cluster=true

#集群其他节点的IP,有多个节点使用逗号隔开
property=replicator.datasource.global.connectionSpec.slave_add=192.168.28.176,192.168.28.177

#集群其他节点端口,有多个节点使用逗号隔开
property=replicator.datasource.global.connectionSpec.slave_port=1521,1521

#ASM用户,此用户必须要有sysasm权限
property=replicator.datasource.oracle_redo.connectionSpec.asm_user=asmfly

#ASM用户密码
property=replicator.datasource.oracle_redo.connectionSpec.asm_password=Flyl234

#ASM侦听服务名
property=replicator.datasource.oracle_redo.connectionSpec.asm_serviceName=+ASM

  

附:创建ASM用户方法:

su - grid
sqlplus / as sysasm
SQL> create user asmfly identified by 123456;  
SQL> GRANT SYSASM TO asmfly;
