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
