一、修改數據庫屬性

EDIT DATABASE 'South_Sales' SET PROPERTY 'LogArchiveFormat'='log_%t_%s_%r_%d.arc';

二、操作步驟

2.1查看DG狀態

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屬性

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查看歸檔日誌格式

SQL> show parameter log_archive_format;

NAME TYPE VALUE

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

log_archive_format string %t_%s_%r.dbf

SQL>

2.4使用DGMGRL修改數據庫屬性

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數據庫重啟

SQL> shutdown immediate;

Database closed.

Database dismounted.

ORACLE instance shut down.

SQL>

SQL>

SQL>

SQL> startup

ORACLE instance started.

2.7查看是否生效

ASMCMD [+datadg/arch] > ls

1_12_954623021.dbf

....省略.........

1_61_954623021.dbf

log_1_62_954623021_585bafa7.arc --格式發生變化

log_1_63_954623021_585bafa7.arc

log_1_64_954623021_585bafa7.arc

ASMCMD [+datadg/arch] >

SQL> show parameter log_archive_format;

NAME TYPE VALUE

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

log_archive_format string log_%t_%s_%r_%d.arc
