ConnStat Remarks

If Perl is not installed on your system, if you are connected to the Internet, you can download a free version from the ActiveState Web site(http://go.microsoft.com/fwlink/?linkid=9247).

The Connstat report consists of three main sections, the Report Header section, the Inbound Connections section, and the Outbound Connections section. Familiarity with FRS concepts and terminology is required in order to interpret these reports.

The Report Header Section

The first line of the Report Header lists the file specified in the ConnStat datafile parameter as well as the date that the file was last modified. The remainder of the Report Header gives information about the FRS service on the host where the input file was generated. The following table describes this information:

Report Element	Description	Comment
Replica	Displays the replica set name and GUID.	SYSVOL replica sets are always called "DOMAIN SYSTEM VOLUME (SYSVOL SHARE)." Replica sets are uniquely identified by the GUID.
Member	Displays the member name. Individual computers in a replica set are referred to as replica members.	Note that for DFS replica sets this name is often a GUID.
ServiceState	Shows the state of the FRS service. Valid return values are between 0 and 7. 0 - Allocated: indicates an initializing state 1 - Initializing: indicates an initializing state 2 - Starting: indicates an initializing state 3 - Active: the replica set is functioning 4 - Stopped: the replica set is stopped with an error 5 - Error: the replica set is stopped with an error 6 - Jrnl_Wrap_Error: the replica set is stopped with an error 7 - Replica_Deleted: indicates the replica set is marked for deletion	The friendly name is displayed in parentheses next to the return value, for example 3 (ACTIVE).
OutLogSecNum	Displays the current outbound log sequence number.
OutLogCleanup	Displays the outbound log sequence number where the next clean-up will begin.
Delta	Represents the difference between OutLogSecNum and OutLogCleanup. This is a good estimation of the number of change orders currently present in the outbound log.
Config Flags	Displays state information about the replica set. Possible values are: Multimaster, Primary, or Seeding.	In multi-master replica sets, any domain controller accepts and replicates directory changes to any other domain controller. A primary flag means the host was a primary member when the replica set was created. The seeding flag, used for SYSVOL only, indicates the replica set is in the initial, seeding state.
Root Path	The root path used by the replica member.
Staging Path	The staging path used by the replica member.
File Filter	Lists file extensions that were excluded during replication, if any.
Directory Filter	Lists directories that were excluded during replication, if any.

The Inbound Connections Section

This section gives state information for all inbound connections for the given member machine. The following table lists columns and descriptions for this section:

Column Heading	Description	Comments
Partner	Displays the name of the immediate inbound partner for this replica member (member machine).	To participate in a valid FRS replica set, each member must have at least one inbound partner.
I/O	Specifies whether the connection is inbound (In) or outbound (Out).	This column appears in both the Inbound and Outbound report sections.
State	Specifies the current inbound connection state.	See the Connection State table in the Connection State Definitions remark for a list of valid Inbound connection states and their meanings.
Rev	Represents operating system version information for the communication protocol of the inbound partner. Valid values include the following: 0 - The connection is not currently joined. 3 - The partner is running either Windows 2000 v. 2195, Windows 2000 v. 2195 SP1, or Windows 2000 v. 2195 SP2 with compression disabled. 4 - The partner is running Windows 2000 v. 2195 SP2 with compression enabled. 7 - The partner is running Windows 2000 v. 2195 SP3. 8 - The partner is running a member of the Windows Server 2003.
LastJoinTime	Displays a timestamp showing when the replica member last successfully joined with this partner.	This data is available only for partners running Windows 2000 SP2 or later.

The Outbound Connections Section

This section gives state information for all outbound connections for the given member machine. The following table lists columns and descriptions for this section.

Note

The first several columns are identical to the Inbound connection report, with some additional information in the State column (see the Connection State table in the Connection State Definitions remark for more information). The columns starting with OLog State contains outbound log-related state information for the connection.

Column Heading	Description	Comments
Partner	Displays the name of the immediate outbound partner for this replica member.
I/O	Specifies whether the connection is inbound (In) or outbound (Out).
State	Specifies the current outbound connection state. See the Connection State table in the Connection State Definitions remark for a list of valid Outbound connection states and their meaning.	In the outbound connections report, the appearance of the tag "-vv" means that this connection is performing a Version Vector-based join operation. Typically this is done when the outbound partner is first added to the replica set or if it is in the process of doing a non-authoritative restore (a D2). Once this initial sync is complete, the connection leaves the VVJoin state.
Rev	Represents operating system version information for the outbound partner’s communication protocol. See the Inbound Connection table in the Inbound Connections Section remark for definitions of the operating system versions.
LastJoinTime	Displays a timestamp showing when the replica member last successfully joined with this partner.	This data is available only for partners running Windows 2000 SP2 or later.
OLog State	Specifies the state of outbound log processing for this connection. OLP_UNJOINED - The partner is not joined. OLP_ELIGIBLE - The partner can accept further change orders (Connection joined, and "change orders out" is less than the max limit). OLP_STANDBY - The partner is ready to join the eligible list. OLP_AT_QUOTA - The partner is at max quota for outstanding change orders. OLP_INACTIVE - The partner is not accepting change orders. Note OLP_AT_QUOTA is a normal condition when FRS is actively replicating because the service always tries to keep eight change orders outstanding on each joined outbound connection.
Leadx	Specifies the index into the outbound log for the next change order to be processed for this connection.
Send Delta	Specifies the difference between OutLogSeqNum (index of the most recent change order in the outlog) and the Leadx value for this connection. In other words, Send Delta specifies the number of change orders that remain to be processed by this connection. A Send Delta of zero means that this connection is fully synchronized at this time. Unless there is very little activity in the replica set or the connection schedule is always on, you are unlikely to find connections with a Send Delta of zero.
Trailx	Specifies the index into the outbound log of the oldest unacknowledged outbound change order. Each change order sent to the partner for this connection must eventually be acknowledged.
Cleanup Delta	Specifies the difference between the Trailx value for this connection and OutLogCleanup index, the latter being the minimum Trailx value for all outbound connections.	Partners having connections with small cleanup deltas should be examined carefully to verify their operational status, since they are often the ones who are furthest behind in replicating content from this member.
LMT	Specifies the difference between the values in the Leadx and Trailx columns. This maximum value is limited by the size of the AckVector, typically 128. A value of 127 in this column indicates that the connection may require investigation.	If the value of LMT isnbsp;127, wait for a while to see if the condition changes. If it does not, first try to delete and recreate the related connection object in the directory service. If the condition persists, then you may need to run a non-authoritative restore on the outbound partner.
COs Out	Specifies the number of active unacknowledged change orders pending at the partner. By default, FRS allows up to 8 change orders to be outstanding at a time on each outbound connection.	This limit is controlled by a registry parameter, which you may want to increase in an environment with high latency communication links. Note that FRS on the partner will try to initiate fetch requests for staging files for all eight change orders concurrently, so increasing this registry parameter will increase the load on the upstream member. See the Microsoft Windows Server 2003 Resource Kit (http://go.microsoft.com/fwlink/?linkid=4546) for more details.
Last VVJoin	Specifies the last date and time that a Version Vector-based join was done on the connection.

The following table lists Connection State values and their meaning:

Connection State	Description
Init	Specifies that the connection is newly allocated.
Unjoined	Specifies that the connection is not yet joined to a partner.
Start	Specifies that the inbound partner has requested a join (StartJoin).
Starting	Specifies that the join has started.
Scanning	Specifies that FRS is scanning the inbound log for the replica set.
SendJoin	Specifies that the scan was completed, and the join request has been forwarded to the partner.
WaitJoin	Specifies that FRS is waiting for a reply from the partner.
Joined	Specifies that the join request succeeded.
Unjoining	Specifies that the join request failed after a series of retries.
Deleted	Specifies that the connection has been deleted.
