A LITTLE EFFORT EVERY DAY.YOU WILL MAKE A BIG DIFFERENCE.
一、修改数据库属性
EDIT DATABASE 'South_Sales' SET PROPERTY 'LogArchiveFormat'='log_%t_%s_%r_%d.arc';
二、操作步骤
2.1查看DG状态
dgmgrl /
DGMGRL> show configuration;
Configuration – dg_config
Protection Mode: MaxAvailability
Members:
orcl – Primary database
orcldg – Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS (status updated 55 seconds ago)
2.2查看DG属性
DGMGRL> show database verbose orcldg;
Database – orcldg
Role: PHYSICAL STANDBY
Intended State: APPLY-ON
Transport Lag: 0 seconds (computed 1 second ago)
Apply Lag: 0 seconds (computed 1 second ago)
Average Apply Rate: 24.00 KByte/s
Active Apply Rate: 0 Byte/s
Maximum Apply Rate: 0 Byte/s
Real Time Query: ON
Instance(s):
orcldg
Properties:
DGConnectIdentifier = 'orcldg'
ObserverConnectIdentifier = ''
LogXptMode = 'sync'
RedoRoutes = ''
DelayMins = '0'
Binding = 'optional'
MaxFailure = '0'
MaxConnections = '1'
ReopenSecs = '300'
NetTimeout = '30'
RedoCompression = 'DISABLE'
LogShipping = 'ON'
PreferredApplyInstance = ''
ApplyInstanceTimeout = '0'
ApplyLagThreshold = '0'
TransportLagThreshold = '0'
TransportDisconnectedThreshold = '30'
ApplyParallel = 'AUTO'
StandbyFileManagement = 'AUTO'
ArchiveLagTarget = '0'
LogArchiveMaxProcesses = '4'
LogArchiveMinSucceedDest = '1'
DbFileNameConvert = ''
LogFileNameConvert = ''
FastStartFailoverTarget = ''
InconsistentProperties = '(monitor)'
InconsistentLogXptProps = '(monitor)'
SendQEntries = '(monitor)'
LogXptStatus = '(monitor)'
RecvQEntries = '(monitor)'
StaticConnectIdentifier = '(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=roidb02)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=orcldg_DGMGRL)(INSTANCE_NAME=orcldg)(SERVER=DEDICATED)))'
StandbyArchiveLocation = '+DATADG/arch'
AlternateLocation = ''
LogArchiveTrace = '0'
LogArchiveFormat = '%t_%s_%r.dbf'
TopWaitEvents = '(monitor)'
Database Status:
SUCCESS
2.3查看归档日志格式
SQL> show parameter log_archive_format;
NAME TYPE VALUE
———————————— ———– ——————————
log_archive_format string %t_%s_%r.dbf
SQL>
2.4使用DGMGRL修改数据库属性
DGMGRL> EDIT DATABASE 'orcldg' SET PROPERTY 'LogArchiveFormat'='log_%t_%s_%r_%d.arc';
Warning: ORA-16675: database instance restart required for property value modification to take effect
Property "LogArchiveFormat" updated
DGMGRL>
DGMGRL> EDIT DATABASE 'orcl' SET PROPERTY 'LogArchiveFormat'='log_%t_%s_%r_%d.arc';
Warning: ORA-16675: database instance restart required for property value modification to take effect
Property "LogArchiveFormat" updated
DGMGRL>
2.5查看是否生效
SQL> show parameter log_archive_format;
NAME TYPE VALUE
———————————— ———– ——————————
log_archive_format string %t_%s_%r.dbf
SQL>
2.6数据库重启
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL>
SQL>
SQL>
SQL> startup

2.7查看是否生效
ASMCMD [+datadg/arch] > ls
