device, says Dr. Mich Talebzadeh, SearchOpenSource.com's Sybase expert. In this tip, Dr. Talebzadeh gives helpful examples of removing unwanted transactions and offers code for boosting your master database capacity.
Removing unwanted transactions
When it is created, the master database has a mixed data and log on the master device. The transaction log is the syslogs table you are referring to, as shown in the example below:
- sp_helpdb master
|master||100.0 MB||sa||1||Jan 15, 2006||mixed log and data|
(1 row affected)
|master||52.0 MB||data and log||Jan 15 2006 1:53AM||36912|
|master||48.0 MB||data and log||Jan 15 2006 1:53AM||48960|
Syslogs is not a normal table. To get rid of an unwanted transaction in the master database, you can do the following:
dump transaction master with truncate_only
Increasing master device space
Alternately, you can increase the size of the master database on master device if you have free space in master device:
- sp_helpdevice master
go device_name physical_name description
master /data2/lon_gen_sql_tst4/master.dat special dsync on directio off default disk physical disk 256.00 MB Free: 120.00 MB
So, in the above example, I have 120MB free on the master device. If I want to expand the master database on the master device by 10MB, I can simply do the following:
- alter database master on master = 10
Extending database by 1280 pages (10.0 megabytes) on disk master
