Release 10.1A: OpenEdge Deployment:
Startup Command and Parameter Reference

Client database connection parameters

Use the parameters listed in Table 3–8 to control how you connect to a specified database.

If you use the Physical Database Name (-db) parameter to specify more than one database when you start a session, specify the connection parameters for each database after the database name to which they apply and before the next -db parameter. OpenEdge applies database connection parameters only to the previously specified database. For example:

mpro [ -db] db1-name [ db1-parameters ] -db db2-name [ db2-parameters ]

Note: OpenEdge implicitly specifies the -db parameter for the first database.

You can specify all other parameters anywhere on the command line. If you specify the same parameter more than once, OpenEdge uses the value you provide for the last instance of the parameter.

-B n	Blocks in database buffers1	Specify the number of database buffer blocks.
-Bp n	Private read-only buffers	Request a number of private read-only buffers.
-brl	Bleeding record lock	Hold a share lock on a released record used by more than one buffer.

-MF n	Delayed BI file write1, 2	Delay writing the last before-image (BI) file records.
-Mm n	Message buffer size.	Specify the message buffer size for network client/server protocols.
-nohostverify	No Host Verify	Turns off host verification for a Secure Sockets Layer (SSL) connection.

-S { servicename | port-number }	Service name	Identify the service and port number to use on the host machine when connecting to a broker process.
-Sn	AS/400 server program name	Specify that the Server program on an AS/400 start with an OpenEdge connection request (SNA only).
-ssl	SSL-based connection	Specifies a Secure Socket Layer connection.
-tstamp	Time Stamp	Uses time stamp information rather than cyclic redundancy (CRC) to enforce consistency between r-code and a schema.
-trig { dir-name | lib-name }	Trigger location	Identify the directory or library containing the 4GL triggers for a database.
-U userid	User ID3	Specify the user ID.
