I don't think anyone has really used the redis plugin in a production setting.

Subject: EPICS Archiver Appliance with Redis Database

 

Hi

 

Has anybody tried running the archiver configured to work with Redis? I have set ARCHAPPL_SHORT_TERM_FOLDER to “redis://localhost:6379/0” in which 0 is the default DB. At first I was using Redis version 3.2.12 which comes with CentOS, the archiver was complaining of SocketExceptions so I tried raising the file descriptors limit using many ways (ulimit, sysctl, somaxconn, etc.) but still same error so I downloaded the latest Redis source and compiled it, in the Redis log I get accepting connections but on archiver logs I get too many “server closed the connection” error. Am I missing something on either Redis or the archiver sides?

 

Best Regards,

Abdalla.
