REPL_INFO_0

The REPL_INFO_0 structure contains configuration information for the file replicator service, including import and export paths and other replication parameters.

typedef struct _REPL_INFO_0 {

Members

rp0_role

Specifies either one or both of the following values.Value	Meaning
REPL_ROLE_EXPORT	Exports directory control information.
REPL_ROLE_IMPORT	Imports directory control information on a Windows NT/Windows 2000 workstation.

rp0_exportpath

Specifies the root directory that holds the exportpath parameter.

rp0_exportlist

Specifies the list of computers or domains to export, using semicolon delimiters. If the list is empty, the function uses the local domain.

rp0_importpath

Specifies the root directory that holds the importpath parameter. If both the export tree and import tree are on an NTFS partition, the file replicator service copies the file permissions as well as the files themselves.

rp0_importlist

Specifies the list of computers or domains to import, using semicolon delimiters. If the list is empty, the function uses the local domain.

rp0_logonusername

Specifies the account the file replicator service attempts to use if the user is not logged on.

rp0_interval

Specifies the interval, in minutes, that elapses between the times the exporter contacts each import server for changes in each top-level directory.

The exporter sends a sync message if it detects a change to the directory since the last contact, or a pulse message if it detects no change. The default setting is 5 minutes.

rp0_pulse

Specifies a multiplier for synchronization of the importer and exporter. The default setting is 2.

If the exporter fails to respond to an importer after the number of minutes obtained by multiplying rp0_pulse times rp0_interval, the importer sends a message to the exporter asking for an update. If the exporter fails to respond again (after the same amount of time) the importer reports that the top-level directory is not synchronized. If the exporter fails to respond a third time, the importer no longer notifies the exporter.

The importer resumes notifying the exporter when the exporter responds and replication is successful.

rp0_guardtime

Specifies the period of time, in minutes (by default), that each file and directory within the replicated directory must be stable before the file replicator service sends a synchronizing message with an updated checksum.

This setting is valid only for top-level directories when the wait-until-stabilized feature is enabled. The value of rp0_guardtime cannot be more than rp0_interval divided by 2.

rp0_random

Specifies the maximum time, in seconds, that import servers wait before requesting an update from the exporter. The default value is 60. You may want to increase this value substantially if you increase rp0_interval to 60 or more minutes. The maximum value is 120.

Import servers generate a random number of seconds, from 0 to the value of rp0_random. After receiving an update notice from the exporter, the import server waits the generated amount of seconds before requesting the replica from the export server. This can prevent the export server from being overloaded with simultaneous update requests.

Requirements

  Windows NT/2000: Requires Windows NT 4.0 or earlier.
  Windows 95/98: Unsupported.
  Header: Declared in Lmrepl.h.
