You can create a parameter file for each database:
Connecting a schema holder
Table 6–1: DataServer connection parameters (2 of 2)
Local Cache
(-cache)
DataServer
(-Dsrv)
Parameter Status Description
Server Join
(-nojoinbysqldb)
Instructs the client to bypass the controlling NameServer
and connect directly to the MS SQL Server DataServer
Broker.
If not specified, the connection is made through the
NameServer.
Required Supplies the password that the DataServer uses to log into
the MS SQL Server database. Different login name and
password combinations allow for different levels of user
privileges.
Optional Specifies that a schema holder is used in single-user mode.
Single–User Mode is the default unless a server is started
for the schema holder.
If not specified, -RO or remote connection parameters are
required.
Optional Specifies that a schema holder is read-only. Connecting a
schema holder as read-only increases processing speed at
client startup time. It also allows multiple client processes
on the same machine to access the schema holder without
starting additional server processes.
If not specified, the database is opened for update as well
as read access.
Optional Specifies that you are using a local cache file for the
schema holder. Create the cache file with the SAVE CACHE
COMPLETE statement.
If not specified, no cache file is used.
See note Specifies options with which you control your ODBC
Driver and DataServer environment. See the “DataServer
options” section on page 8–4 and the “Using MS SQL
Server and DataServer options” section on page 8–6 for
more information.
Note: When you specify a list of -Dsrv parameters, be
sure not to include any spaces anywhere in this list.
Optional Specifies that the client evaluates and performs queries that
have joins. This might slow performance, but it provides
results that are consistent with the query of an OpenEdge
database.
Use -nojoinbysqldb at startup time.
If not specified, the server will perform joins, but results
may not be consistent with identical joins run against an
OpenEdge database.
• For a local DataServer, the parameter file must contain the -db parameter and can
optionally contain the -Dsrv, -U, and -P connection parameters, depending on the
requirements of the data service.
