Primary 1seoul110GB리눅스 설치RAC 1번RAC 구축 후 DB 생성까지 완료
Primary 2seoul210GBPrimary 1번 복제RAC 2번
Standbybusan10GBPrimary 1번 복제RestartRestart 구축 및 DB 엔진까지 설

※ 리눅스 기반의 Primary-Standby 환경으로 구성합니다.

B) 스토리지

Primary100GBDynamic / NormalRAC1 노드 로컬 스토리지디스크 사용량을 최소화하기 위해 Dynamic으로 생성합니다.
100GBDynamic / NormalRAC2 노드 로컬 스토리지OS까지 설치된 1번 노드를 복제하여 사용하면 편리합니다.
1GBFixed / Shareable공유 OCR / Vote 저장 영역  공유(shareable) 디스크로 사용하기 위해서는 Fixed Size로 생성해야 합니다.

srvctl config network -netnum [네트워크 번호]
[root@seoul1 ~]# srvctl add network -k 2 -S 10.0.7.0/255.255.255.0/ens38

[root@seoul1 ~]# srvctl config network -netnum 2
2 네트워크가 존재합니다.
서브넷 IPv4: 10.0.7.0/255.255.255.0/ens38, static
서브넷 IPv6:
핑 대상:

III. 사전 환경 구성

1. 아카이브 로그 환경 설정

A) Data Guard를 위한 아카이브 로그 파라미터 설정

sys 유저로 primary에서 수행
ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=([primary 글로벌 DB명],[standby 글로벌 DB명])';
-- ALTER SYSTEM SET LOG_ARCHIVE_FORMAT='%t_%s_%r.arc' SCOPE=SPFILE;
SQL> ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=(ORCLDB,ORCLDB_STBY)';

System altered.


B) 아카이브 로그 모드 활성화

sys 유저로 primary에서 수행
ARCHIVE LOG LIST
SHUTDOWN IMMEDIATE
STARTUP MOUNT
ALTER DATABASE ARCHIVELOG;
ALTER DATABASE OPEN;
SELECT log_mode FROM v$database;
SQL> ARCHIVE LOG LIST
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     14
Next log sequence to archive   16
Current log sequence           16


C) 강제 로그 적용 모드 활성

sys 유저로 primary에서 수행
ALTER DATABASE FORCE LOGGING;
ALTER SYSTEM SWITCH LOGFILE;
SELECT FORCE_LOGGING FROM V$DATABASE;
SQL> ALTER DATABASE FORCE LOGGING;

Database altered.

SQL> SELECT FORCE_LOGGING FROM V$DATABASE;

FORCE_LOGGING
--------------------------------------------------------------------------------
YES


2. 파라미터 설정

A) DB명 관련 파라미터 조회

DB name 파라미터 값 조회
SELECT name, db_unique_name FROM v$database;
SQL> SELECT name, db_unique_name FROM v$database;

NAME                        DB_UNIQUE_NAME
--------------------------- --------------------
ORCLDB                      ORCLDB


B) Data Guard 관련 파라미터 (Fetch Archive Log, Standby File Management) 설정

sys 유저로 primary에서 수행
ALTER SYSTEM SET FAL_CLIENT=[primary 글로벌 DB명];
ALTER SYSTEM SET FAL_SERVER=[standby 글로벌 DB명];
ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO;
SQL> ALTER SYSTEM SET FAL_CLIENT=ORCLDB;

System altered.

SQL> ALTER SYSTEM SET FAL_SERVER=ORCLDB_STBY;

System altered.

SQL> ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO;

System altered.


C) Standby Redo 로그 추가

Standby Redo 그룹 생성 (primary와 동일한 갯수와 사이즈로 생성)
ALTER DATABASE ADD STANDBY LOGFILE THREAD [THREAD 번호] GROUP [그룹 번호] ('[로그 파일 경로 및 파일 이름]') SIZE [로그 파일 크기];
SQL> select THREAD#, f.GROUP#, TYPE, BYTES/1024/1024 mb, MEMBER from v$logfile f, v$log l where l.GROUP#(+) = f.GROUP# order by 1, 2;

3. Standby 환경 설정

A) 디렉토리 생성

oracle 유저로 standby 서버에서 수행
mkdir -p [데이터 파일 저장 경로]
mkdir -p [FRA 할당 경로]
mkdir -p [adump 파라미터 경로]
[ORCLDB@busan:~]$ mkdir -p $ORACLE_BASE/admin/ORCLDB/adump


B) 패스워드 파일 복제

oracle 유저로 primary에서 standby로 전송 (또는 standby에서 생성)
scp $ORACLE_HOME/dbs/[패스워드 파일] [oracle 유저]@[standby 호스트명]:[$ORACLE_HOME/dbs 경로]
--orapwd file=$ORACLE_HOME/dbs/orapw[DB명] password=[sys 계정 암호] entries=10 format=12

V. Data Guard Broker 설정

1. Data Guard Broker 활성화

A) Data Guard Broker 설정 위치 변경

DG Broker 설정 파일 경로 변경 (클러스터 환경)
ALTER SYSTEM SET dg_broker_config_file1='[설정 파일 저장 경로 및 파일명1].dat' SCOPE=both SID='*';
ALTER SYSTEM SET dg_broker_config_file2='[설정 파일 저장 경로 및 파일명2].dat' SCOPE=both SID='*';
SELECT NAME, VALUE FROM V$PARAMETER WHERE NAME LIKE 'dg_broker_config_file%';
SQL> ALTER SYSTEM SET dg_broker_config_file1='+DATA/ORCLDB/dr1orcldb.dat' SCOPE=both SID='*';

System altered.

SQL> ALTER SYSTEM SET dg_broker_config_file2='+FRA/ORCLDB/dr2orcldb.dat' SCOPE=both SID='*';

System altered.
SQL> ALTER SYSTEM SET dg_broker_config_file1='+DATA/ORCLDB_STBY/dr1orcldb.dat' SCOPE=both;

System altered.

SQL> ALTER SYSTEM SET dg_broker_config_file2='+FRA/ORCLDB_STBY/dr2orcldb.dat' SCOPE=both;

System altered.

클러스터에 설정할 경우 모든 노드에서 액세스할 수 있는 공유 스토리지에 설정 파일을 저장합니다.

B) db_broker_start 파라미터 설정

sys 유저로 primary와 standby에서 모두 수행
ALTER SYSTEM SET dg_broker_start=true;
SQL> ALTER SYSTEM SET dg_broker_start=true;

System altered.
SQL> ALTER SYSTEM SET dg_broker_start=true;

System altered.


2. Data Guard Broker 환경 구성

A) Oracle Data Guard command-line interface(이하 DGMGRL) 접속

E) 정적 연결 식별자 설정

DB별 접속 정보 확인 및 변경
SHOW DATABASE [standby 글로벌 DB명] StaticConnectIdentifier
EDIT DATABASE [standby 글로벌 DB명] SET PROPERTY StaticConnectIdentifier = '[standby 접속 정보]';
DGMGRL> SHOW DATABASE orcldb_stby StaticConnectIdentifier
  StaticConnectIdentifier = '(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.0.1.105)(PORT=1523))(CONNECT_DATA=(SERVICE_NAME=ORCLDB_STBY_DGMGRL)(INSTANCE_NAME=ORCLDB)(SERVER=DEDICATED)))'

DGMGRL> EDIT DATABASE orcldb_stby SET PROPERTY StaticConnectIdentifier = '(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=busan-dg)(PORT=1625))(CONNECT_DATA=(SERVICE_NAME=ORCLDB_STBY_DGMGRL)(INSTANCE_NAME=ORCLDB)(SERVER=DEDICATED)))';
Property "staticconnectidentifier" updated

DGMGRL> SHOW DATABASE orcldb_stby StaticConnectIdentifier
  StaticConnectIdentifier = '(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=busan-dg)(PORT=1625))(CONNECT_DATA=(SERVICE_NAME=ORCLDB_STBY_DGMGRL)(INSTANCE_NAME=ORCLDB)(SERVER=DEDICATED)))'


F) Data Guard Broker 설정 백업

DGMGRL 에서 수행
EXPORT CONFIGURATION TO dg_config.xml
DGMGRL> EXPORT CONFIGURATION TO dg_config.xml
Succeeded.

백업 파일은 XML 형태로 덤프 파일 경로에 저장됩니다.

복구 명령어는 아래와 같습니다.

IMPORT CONFIGURATION FROM dg_config.xml

3. Data Guard 구성 결과 확인 및 추가 작업

A) 데이터베이스 상태 확인

Primary DB와 Standby DB에서 수행
SELECT name, db_unique_name FROM v$database;
SELECT db_unique_name, open_mode, database_role, switchover_status, dataguard_broker FROM v$database;
SQL> SELECT name, db_unique_name FROM v$database;

NAME                        DB_UNIQUE_NAME
--------------------------- --------------------
ORCLDB                      ORCLDB

SQL> SELECT db_unique_name, open_mode, database_role, switchover_status, dataguard_broker FROM v$database;

DB_UNIQUE_NAME       OPEN_MODE            DATABASE_ROLE        SWITCHOVER_STATUS    DATAGUARD_BROKER
-------------------- -------------------- -------------------- -------------------- ------------------------
ORCLDB               READ WRITE           PRIMARY              TO STANDBY           ENABLED
SQL> SELECT name, db_unique_name FROM v$database;

NAME                        DB_UNIQUE_NAME
--------------------------- --------------------
ORCLDB                      ORCLDB_STBY

SQL> SELECT db_unique_name, open_mode, database_role, switchover_status, dataguard_broker FROM v$database;

DB_UNIQUE_NAME       OPEN_MODE            DATABASE_ROLE        SWITCHOVER_STATUS    DATAGUARD_BROKER
-------------------- -------------------- -------------------- -------------------- ------------------------
ORCLDB_STBY          READ ONLY WITH APPLY PHYSICAL STANDBY     NOT ALLOWED          ENABLED


B) Local listener 설정

서버별 TNS 설정에 맞게 적용
alter system set local_listener='<서비스 네트워크 접속 정보>,<DG 전용 네트워크 접속 정보>' scope=both;
SQL> ALTER SYSTEM SET local_listener="(ADDRESS_LIST= (ADDRESS=(PROTOCOL=TCP)(HOST=busan)(PORT=1523)) (ADDRESS=(PROTOCOL=TCP)(HOST=busan-dg)(PORT=1625)))";

System altered.

SQL> alter system register;

System altered.

기존 설정된 local listener 파라미터에 DG 전용 리스너를 추가합니다.

C) 아카이브 로그 삭제 방지 정책 추가

Primary와 Standby의 RMAN 설정 변경
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;

using target database control file instead of recovery catalog
new RMAN configuration parameters:
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
new RMAN configuration parameters are successfully stored
RMAN> CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;

using target database control file instead of recovery catalog
new RMAN configuration parameters:
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
new RMAN configuration parameters are successfully stored

Standby에 적용되지 않은 아카이브 로그가 삭제되어 데이터 손실이 발생하지 않도록 아카이브 삭제 정책을 수정합니다.

Primary와 Standby에서 각각 수행합니다.
