Zero Availability Index and Slow sever response for User

HCL Domino Domino Forum
1

Hello,

I am using domino server v9.0.1 FP5 on windows 2012 Hyper-V.

I am experiencing zero availability index very often during the day and during that instant the user experience very slow response from the server and their clients hangs.

I have monitored following things during the instant of zero availability

1- Disk I/O-----> Disk I/O is not showing any abnormal hikes

2- Network Response-------> During the event I pinged the server continuously during the event and network response is 1ms to 10ms

3- Domino Server Tasks-------> During the event the Indexer task was consuming around 9% processing and all other tasks were mostly IDLE or using low resources

4- Memory Consumption for both domino server tasks and over all OS----> It was also not at all alarming

I had a problem with the availability index being too low on a fast server. take a look at this article:

Daniel Nashed's Blog http://blog.nashcom.de/nashcomblog.nsf/dx/configuring-sai-loadmon-for-fast-servers.htm?opendocument&comments

and these notes.ini settings:

Server_MinPossibleTransTime=1500
Server_MaxPossibleTransTime=20000000

after you add the settings, shutdown the server, delete loadmon.ncf file, then restart the server

then use the ‘show ai’ command when the server is under load to get a recommendation for the Server_Transinfo_Range.

then see if the index behaves itself better…

Hello Abu Ammar!

I strongly recommend you to create a PMR for further investigation.
A manual NSD collected on slow performance time will be requested trying to identify the cause of the issue.

Best Regards!
