The information in this article applies to: 

  - Microsoft SQL Server version 4.2 for OS/2

SUMMARY

When SQL Server is installed, the user is asked to specify the amount of disk space to be allocated for master device. This value is different from what shows up when an "sp_spaceused master" is executed after installation.

MORE INFORMATION

When you instruct the SQL Server installation program to create a 16-megabyte (MB) master database, this value (in this case, 16 MB) is actually used in the DISK INIT command to indicate the amount of disk space that should be allocated to the master database logical device (MASTER.DAT), where the master database resides. The size of any device can be found by executing the stored procedure sp_helpdevice.

The default value for the size of the master database as created by the installation program is 3 MB. The installation program then increases the size of the master database to 8 MB (5 MB for OS/2 versions prior to 4.2b). Thus, 8 MB (5 MB for OS/2 versions prior to version 4.2b) is the amount of space used on the master database device and is the size of the master database.
