OpenEdge Data Management: DataServer for Microsoft SQL Server

ODBC options
Table 56: DataServer options (2 of 3)
Option Description
LOGGINGLEVEL Specifies the level at which log entries
are written. For more information, see
the “Analyzing application execution
with Enhanced Logger” section on
page 230.
LOGENTRYTYPES Specifies one or more types of log
entries. For more information, see the
“Analyzing application execution with
Enhanced Logger” section on page 230.
PRGRS_MAX_BLOCKSIZE Specifies the size in bytes of the total
allowable memory for all block cursors.
By default, this value is set to
ODBC_DEF_MAXBLOCKSZ, or 1MB.
PRGRS_MINBUF Specifies the minimum size of the buffer
used to get data from the DataServer.
Use this keyword only with drivers that
fail to fetch large records. The default
value is 500 bytes. If you specify a value
smaller than the default, OpenEdge
uses the default value.
The optimal setting for PRGRS_MINBUF is
the size of the largest record data size
plus 500 bytes. This can prevent
run-time record expansion during the
retrieval of query results.
Note: Do not use this option when the
-Dsrv BINDING switch is set to 3. With
the binding set to 3, the size of the data
is known, and this switch will cause the
allocation of unneeded additional
memory.
PRGRS_NATIVE_LOCKWAIT Specifies the server-based wait period in
which the server will block wait for
access to a locked resource before
returning to a MSS DataServer client
application. The default value is zero,
meaning that control is returned to the
client immediately upon receiving a lock
condition from the server.
Note: A number of milliseconds is
recommended at startup for
transactional applications that anticipate
a higher contention for server resources.
The optimal value is application-specific.
PRGRS_NO_INDEX Suppresses index creation at schema
import time. If you specify a value of 1 for
-Dsrv PRGRS_NO_INDEX, you must
create the indexes manually in the
schema holder.
