Physical Standby тохируулах

batmunkh · December 28, 2016, 5:36pm

Data Guard-ийн талаар оруулсан танилцуулга мэдээллийг энд дарж үзнэ үү.

Уг тохиргоог хэд хэдэн янзаар хийж болох боловч би энэ удаад өөрийн мэдэх байж болох хамгийн товч хувилбарыг орууллаа.

Үндсэн бааз - Primary (node111.oracle.me) - ORCL
Хуулбар бааз Standby (node112.oracle.me) - SBY1

Primary тохиргоо (node111.oracle.me)

Archivelog идэвхжүүлээгүй бол идэвжүүлээрэй.

SQL> alter system set log_archive_config='dg_config=(ORCL,SBY1)';

Лог файлууд архивлагдсан эсэхийг дараах коммандаар шалгана.

Primary серверийг зааж өгнө. Oracle 11g дээр тохируулах шаардлагагүй бөгөөд Oracle 12c дээр харин заавал тохируулж өгнө.

SQL> alter system set fal_server=ORCL;

pfile-ийг standby-д зориулж засварлана.

rman connect хийж байгаа комманд

batmunkh · November 20, 2018, 12:20pm

Өдөр RAC to Single DG тохируулж байхад гарч байсан алдаа байнаа. ASM -с файлсистем рүү хөрвүүлж чадахгүй болохоор нь set newname ашиглаад явуулчихсан. Араас нь duplicate коммандаа залгуулаад явуулна .

run{
    set newname for datafile 1 to '/u01/app/oracle/oradata/ORCL/datafile/01.dbf';
    set newname for datafile 2 to '/u01/app/oracle/oradata/ORCL/datafile/02.dbf';
    duplicate target database for standby from active database nofilenamecheck;
}

19505 яг санаж байна db_file_name_convert болохгүй байна лээ. 11.2.0.4 байсан билүү дээ.

Хэрвээ standby logfile нэмсэн бол “using current logfile” option - г нэмээд real-time apply хийдэг. DR бааз нь Standby logfile - с recover хийнэ гэсэн үг.
alter database recover managed standby database using current logfile disconnect from session;

Одоогийн хоцроод байгаа нь доорх шиг холбосон байж магад, эсвэл standby logfile байхгүй,
alter database recover managed standby database disconnect from session;

Мөн дата өөрчлөлт их байдаг бол standby logfile чинь багадаж байж магадгүй

Hi,

Standby database serveree restart хийсний дараа баазаа Stanby-аар асаах гэсэн ийм алдаа зааж байна. ALTER database recover managed standby database disconnect from session;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE disconnect from session; хийгээд archive log-уудаа хуулахгүй байна. Үүнийг хэрхэн шийдвэрлэх вэ? Туслаач нөхдөө

recover managed standby database disconnect;

гээд хэсэг хүлээ. recovery хэрэгтэй гэсэн үг. mount горимоос хэсэг явуулах шаардлагатай.

Standby database server дээрээ
alter database open; хийхээр ийм алдаа өгч байгаа.
Дараах 2 командыг ажиллуулаад дахин alter database open; хийсэн ялгаагүй байгааг хэрхэн шийдвэрлэх вэ? guys

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT;

recovery процессоо нилээд явуулж байгаад өгөгдөл зэрэгцсэний дараа л open хийж болно доо. Шууд хоцрогдолтой үед болохгүй

RMAN-н дараах командаар файлуудаа зэрэгцүүлээд асуудлаа шийдвэрлэсэн.

duplicate target database for standby from active database nofilenamecheck;

duplicate хийсний дараагаар recovery процессийг ажиллуулж өгөгдөл тэнцтэл хүлээж таардаг.
