OpenEdge Data Management: DataServer for Microsoft SQL Server

Troubleshooting
Tuning your environment with the –Dsrv startup parameter
8–2
The DataServer (–Dsrv) startup parameter allows you to use special DataServer options to tune
your environment. You pass these options as arguments to –Dsrv when connecting to a MS SQL
Server database.
There are two versions of the syntax, as follows:
Syntax
CONNECT data-source-name -ld logical-name -dt MSS
-Dsrv arg1,val1 -Dsrv arg2,val2 -Dsrv arg3,val3...
Syntax
CONNECT data-source-name -ld logical-name -dt MSS
-Dsrv arg1,val1,arg2,val2,arg3,val3...
In this syntax:
• The schema holder is already connected.
• The data–source–name argument is the name of the data source and the logical–name
argument is its logical name, which is defined when you create your schema image.
• You pass the options as the argn,valn pairs.
Here is an example of how to use the CONNECT statement with the –Dsrv parameter:
CONNECT mssql_db -ld mydb -U x -P y
-Dsrv qt_debug,EXTENDED
-Dsrv PRGRS_IDBUF,100
-Dsrv PRGRS_MINBUF,10000
-Dsrv MAX_R,10000.
Note that MAX_R is an abbreviation of MAX_ROWS. You can abbreviate option names as long as
they identify parameters uniquely.
Both the syntax statements and the example show the use of the –Dsrv startup parameter in
CONNECT statements. You can also specify –Dsrv options in a parameter file, on a program item
command line, or in the Connection Parameters field in the Database Connect dialog box.
