SYBASE扩充日志段空间

有时候日志段空间满了使用下列语句也无济于事，又不能直接重启库，就加空间应急，
dump tran QAS with truncate_only

dump tran QAS with no_log

sp_helpdevice
go
sp_helpdb QAS
go


sp_helpsegment logsegment
 
go

声明设备

use master

DISK INIT
name = 'QAS_data_004',
physname = 'E:sybaseQASsapdata_1QAS_data_004.dat',
size = '100G',
directio = true
go

DISK INIT
name = 'QAS_log_004',
physname = 'E:sybaseQASsaplog_1QAS_log_004.dat',
size = '20G',
directio = true
go

更改数据库

ALTER DATABASE QAS
ON QAS_data_004 = '50G'
LOG ON QAS_log_004 = '20G'
go
