Portal Properties
Export Operation Performance Portal Property
When you execute an export operation, the extraction of data from the entities that you designate is
performed by a message processor thread that runs on each Worker node in your Cisco WebEx Social
cluster. If the cluster includes multiple Worker nodes, the message processor thread runs in parallel on
each of these nodes, which reduces the time that data extraction requires.
performed by a message processor thread that runs on each Worker node in your Cisco WebEx Social
cluster. If the cluster includes multiple Worker nodes, the message processor thread runs in parallel on
each of these nodes, which reduces the time that data extraction requires.
By default, one message processor thread runs on each Worker node, but running multiple threads further
reduces the time that data extraction requires. The extra.migration.reciever.count portal property lets you
designate that additional message processor threads (up to a total of four threads) run on each Worker
node when you execute an export operation.
reduces the time that data extraction requires. The extra.migration.reciever.count portal property lets you
designate that additional message processor threads (up to a total of four threads) run on each Worker
node when you execute an export operation.
Valid values for the extra.migration.reciever.count portal property are the integers 0 through 3. A value
of 0 means no additional message processor threads, so with this value, 1 thread runs on each Worker
node. A value of 1 means that 1 additional thread, or a total of 2 threads, run on each Worker node.
Similarly, values of 2 or 3 indicate a total of 3 threads or 4 threads, respectively.
of 0 means no additional message processor threads, so with this value, 1 thread runs on each Worker

Similarly, values of 2 or 3 indicate a total of 3 threads or 4 threads, respectively.
The default value is 0 (no additional threads). To change the value, see the

shows recommended
values for the extra.migration.reciever.count portal property, based on the following factors:
•
Cisco WebEx Social environment—Whether end users are performing Cisco WebEx Social
activities when you execute an export operation and the relative amount of data that you are
exporting
