DM8: Single database and single instance to build a local data guard service

DM8: Single database single instance to build local data guardian service

1. Prepare the database configuration file:

1.1, dm.ini

MAL_INI=1ARCH_INI=1

1.2, dmarch.ini

[ARCHIVE_LOCAL1]ARCH_TYPE = LOCALARCH_DEST = /home/dmdba/dmdata5236/dmarchARCH_FILE_SIZE = 1024ARCH_SPACE_LIMIT = 10240ARCH_FLUSH_BUF_SIZE = 0ARCH_HANG_FLAG = 1

1.3, dmmal.ini

The dm.ini value of 2 parameters is consistent with the dmmal.ini value

dm.ini	dmmal.ini
INSTANCE_NAME	MAL_INST_NAME
PORT_NUM	MAL_INST_PORT

MAL_CHECK_INTERVAL=30MAL_CONN_FAIL_INTERVAL=30[MAL_INST1]MAL_INST_NAME=DMSERVERMAL_HOST=192.168.200.203MAL_PORT=61141MAL_INST_HOST=192.168.200.203MAL_INST_PORT=5236MAL_DW_PORT=52141MAL_INST_DW_PORT=33141

1.4, dmwatcher.ini

[GRP1]DW_TYPE=LOCALDW_MODE=MANUALDW_ERROR_TIME=30INST_RECOVER_TIME=30INST_ERROR_TIME=30INST_OGUID=453332INST_INI=/home/dmdba/dmdata5236/DAMENG/dm.iniINST_AUTO_RESTART=1INST_STARTUP_CMD=/home/dmdba/dmdbms/bin/DmServiceDM5236 startRLOG_SEND_THRESHOLD=0

1.5 Config Database oguid

Use disql or manager to connect to the database instance for execution, which is consistent with the INST_OGUID value in dmwatcher.ini:

ALTER DATABASE MOUNT;SP_SET_OGUID(453332);ALTER DATABASE OPEN;

1.6, dmwatcher (register service with root user)

[[email protected] root]$ cd /home/dmdba/dmdbms/script/root[[email protected] root]$ ./dm_service_installer.sh -t dmwatcher -p DMWATCHER -watcher_ini /home/dmdba/dmdata5236/DAMENG/dmwatcher.ini

1.7, build a video ++ close the database instance service for testing"" "database instance service is automatically pulled up by the data guardian service"""ok

1.7.1, DM8 single database single instance"" build data guardian service

1.7.2, DM8 single database single instance" "Register Data Guardian Service
