Hi,
I am investigating some issues with the invocation of the correct processes between the A&B leg of a DMA pair. However, I don't actually have a reference of exactly what should be running. I have 5 slprotocol and 5 slport running on a single DMA as well, which seems strange to me.
If anyone had such a reference guide, I would be very grateful
Hi Floris,
Thanks for the speedy response, and useful info. I have looked at the documentation, and as I then understand, I should see each of these running on the live DMA, (with some as mentioned running multiple times in a pool depending on DMA configuration).
For the offline DMA what subset of these processes should I see, or is it better to ask, which processes should I not see?
Hello Garry,
i will reply based on my experience, I hope that a person with more experience could validate what i am writing here.
in normal situations, you see 5 times SLProtocol, when you check with Microsoft platform you will see SLProtocol0, SLProtocol1, SLProtocol2, SLProtocol3 and SLProtocol4.
If you check via Windows task manager, you will see 5 times SLProtocol with different PIDs.
when you have a failover pair you have 2 agents, one is online the other offline.
IF you start up the offline agent and this agent was not online, the SLProtocol(s) processes wont be present in the Windows task manager. Note that if you switch the agents and it becomes online, you will see the processes present in the Windows task manager on both nodes.
Hi Garry,
DataMiner processes | DataMiner Docs seems like a comprehensive list of the DataMiner processes.
Regarding the SLProtocol and SLPort processes, we have created pools of certain processes to resolve the memory limitations of 32-bit processes, but also to help isolate problems occasionally. SLProtocol exists as an optionally 64-bit process since 10.1.8, and will be replace the 32-bit version by default as of 10.3.9.
The SLSNMPManager process always has 3 instances, one for each SNMP version, due to how the WinSNMP library handles SNMP versions.
Hi Garry, the 3 SLSNMPManager instances should always be running. SLProtocol and SLPort will be started as elements are started during a failover switch. However, after the main agent takes over again from the failover agent, these processes are not explicitly stopped.
Also, apologies for the slow response, dojo users in general are not notified of new posts on a question that they reply to, only comments trigger a notification. So if you post a new answer, you may want to post a comment too to get a specific user’s attention.
