7 Working with the Replication Monitor

This chapter describes the replication monitor page. The replication monitor page allows you to monitor and analyze TimesTen targets that use replication to replicate objects to other databases.

Topics include:

Viewing the replication monitor

In order to view the replication monitor metrics, make sure you have configured replication for your TimesTen target and make sure the replication agent is up.

Navigate to the TimesTen target page. For information on navigating to the TimesTen target page, see "Navigating to the TimesTen target page".

From the TimesTen IMDB menu, select Additional Links, then select Replication Monitor.

Analyzing information on the TimesTen replication monitor

The TimesTen replication monitor page consists of two areas each of which have been customized specifically for TimesTen replication.

The top area consists of:

The bottom area consists of:

Summary

Figure 7-1 Replication summary

Description of Figure 7-1 follows
Description of "Figure 7-1 Replication summary"

This region identifies your database and the configuration of your database, including:

  • Datastore name

    This value is taken from the last part of the path to the datastore. For example, if the path to the datastore is /var/tt/rep_masterdb1, the datastore name is rep_masterdb1.

  • Hostname

    The name of the host where TimesTen is running.

  • Port

  • Replication policy

Status

Figure 7-2 Replication status

Description of Figure 7-2 follows
Description of "Figure 7-2 Replication status"

The replication status area shows overall information relative to the current state of the replicated operations. If the most recent log file number is much greater than the last log file held by replication, then the replication agent has fallen behind in transmitting the recently created transactions.

Values for Replication Agent are Up, Down, or N/A. If you have not configured a replication scheme, then the value is N/A.

Aggregates

Figure 7-3 Replication aggregates

Description of Figure 7-3 follows
Description of "Figure 7-3 Replication aggregates"

This region shows the total number of replicated transactions from the database since the time the database was loaded into memory.

Replication peers

Choose the Replication peers tab.

Figure 7-4 Replication peers

Description of Figure 7-4 follows
Description of "Figure 7-4 Replication peers"

The replication peers table is common to any database regardless of whether the database is in the role of transmitter or receiver. The table shows the list of peers to the database.

Replication log holds

Choose the Replication log holds tab.

Figure 7-5 Replication log holds

Description of Figure 7-5 follows
Description of "Figure 7-5 Replication log holds"

The replication log holds table shows information for databases that replicate transactions to other databases. The table shows replication log holds.

Transmitter threads status

Choose the Transmitter threads status tab in the middle of the page.

Figure 7-6 Transmitter threads status

Description of Figure 7-6 follows
Description of "Figure 7-6 Transmitter threads status"

The transmitter threads status table shows information for databases that replicate transactions to other databases. The table shows the status of transmitter threads for the database.

Receiver threads status

Choose the Receiver threads status tab.

Figure 7-7 Receiver threads status

Description of Figure 7-7 follows
Description of "Figure 7-7 Receiver threads status"

The receiver threads status table shows information for databases that receive transactions from other databases. The table shows the status of receiver threads for the database.

Performance

Choose the Performance tab.

Figure 7-8 Replication performance

Description of Figure 7-8 follows
Description of "Figure 7-8 Replication performance"

This region uses a line graph to show the outbound replication rate of transactions replicated per minute.

The X-Axis represents Time. The Y-Axis represents the number of transactions replicated per minute.
