|Oracle® Enterprise Manager System Monitoring Plug-in for Oracle TimesTen In-Memory Database User's Guide
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.
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.
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:
This region identifies your database and the configuration of your database, including:
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
The name of the host where TimesTen is running.
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.
This region shows the total number of replicated transactions from the database since the time the database was loaded into memory.
Choose the Replication peers tab.
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.
Choose the Replication log holds tab.
The replication log holds table shows information for databases that replicate transactions to other databases. The table shows replication log holds.
Choose the Transmitter threads status tab in the middle of the page.
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.
Choose the Receiver threads status tab.
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.
Choose the Performance tab.
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.
