This parameter indicates the name of a dummy file or table to be used for

mapping schema/DDL Records from all of the sourcefile partitions, even

when the partitions do not exist at the start of replication. The

Dummy_fname must exist at start, and must be of identical schema/DDL

Record representation as SOURCEFILE.

MAPTOTEMPLATE { ON }

4.070 5.001 OFF OFF ON No

By setting this parameter ON, it indicates the use of a common

MAPTOFILE for multiple DBS objects. The default is OFF, requiring a

distinct MAPTOFILE file for each DBS object. This parameter is typically

used when the file attributes are the same for many files within multiple

subvolumes and eliminates the need for many MAPTOFILE’s of similar

characteristics. Note that a DBS object logical association is used within

the Consumer for mapping the source to the proper target file. As a result

of this association, for NSK-to-NSK environments using STP TCP/IP

(client/server CONS’s), the DBS object names must be the same for both

the client CONS and the server CONS.

This parameter was rendered OBSOLETE in release 5.001 of NonStop

HP Shadowbase in DBS that are configured to replicate dynamic Enscribe

file sets (ie a ‘daily’ file).

MAXRETRIES number

Initial Changed

Version Version Values Default Minimum Maximum Alter

4.070 -1 -2 32767 No

This parameter defines the number of retries following an error condition

for SQL and Enscribe I/O operations. The valid range is -2 to 32767 and

takes the following values:

MAXRETRIES = -2: Retry indefinitely.

MAXRETRIES = -1: Use the value set for the CONS.

MAXRETRIES = 0: No retries.

MAXRETRIES > 0: The number of times to retry the operation after

the initial failure.

The default value is -1: use the value set for the CONS. Note that this

parameter can’t be altered at this time.
