Scaling guidelines for 5620 SAM OSS Clients
OSS client limits
OSS client limits
There can be a maximum of 20 5620 SAM OSS-JMS Clients. Greater than 10 5620 SAM
OSS-JMS Clients requires a SAM Server with a minimum of 16 CPU Cores.
The number of 5620 SAM OSS-HTTP Clients supported by a 5620 SAM Server
workstation is 2 times the number of CPU cores with at least 10 and at most 30 clients
supported.
The 3GPP interface can support up to 3 notification clients and 3 action/request clients.
The maximum number of concurrent findToFile operations supported is 5.
5620 SAM OSS Clients using JMS
5620 SAM OSS Clients using JMS
As of 5620 SAM 9.0R5, OSS Clients using JMS durable connections have a maximum
message rate comparable to non-durable clients.
Network latency between the 5620 SAM Server and a 5620 SAM OSS Client will reduce
the JMS message rate. For durable JMS clients, the Duplicate OK method will allow for a
higher message rate than the Auto Acknowledge method. Refer to the 5620 SAM-O OSS
Interface Developer Guide for more information.
5620 SAM is also able to deliver hundreds of messages per second to a non-durable 5620
SAM OSS client.
