Hot Topic Analytics problem

Jump to solution

Hello,

When we select Hot Topic Analytics, we are greeted with the error message "Cannot create Hot Topic chart (No engines available)".
We have noticed that Content1 server service isn't running on the Smart Analytics server and when we manually start it, it instantly stops. The application log of content1 displays "Persistent engine is inconsistent (IndexCompression) - Exiting".
Are these errors related?

Please bear in mind that Hot topics has been working properly for a while now with the OOB data and, to our knowledge, we haven't touched the Smart Analytics server in any way, apart from some necessary reboots.

What is your suggested course of action in order to fix this problem?

Thank you in advance!

sorry!

inside the content1 folder...you have to delete all folders (exept "license" and "uid")

don't delete the files in the config files inside the content1 folder

the folder will be recreated when you restart the service

is it on the production system?

Sounds like an index problem.

did you stopped the services correctly before rebooting the idol server?

is the idol server running on linux or windows?

we had the same issue on windows (you have to disable the AV for the indexes, check the idol white paper)

you have to recreate all the indexes...or just try it for the content1 (Hot Topics and Smart Ticket)

stop all services, delete the content1 folder (or back it up) restart the services and then you have to perform a new Hot Topic reindex

Thank you for your feedback.

We are on a test system with windows and we are trying to figure out what is the root cause of this problem, before we move on to production. Indeed, we have rebooted our system without first stopping the services. Do you know if there is a recommended order to stop the services before a hardware reboot?

We'll follow your suggestions and get back to you.

my personal advice...don't use it on windows...it's more stable on linux!

Exclude the Smart Analytics from the AV on access scan!

Just stop the services from top down

Hello again. Just one clarification regarding the content1 folder: this folder also has configuration files and executables. When you say to delete content1, do you mean a particular subfolder that contains specific files?

Thank you very much for your help!

Hello,

we've had the same problem with Hot Topic Analytics (Windows server) and we are investigating it. Does it mean that each time the smart analytics server shuts down, there might be necessary to recreate all the indexes? It will be difficult to convince the client to accept this solution for the production.

Thank you in advance for your help

BR,

If the server has an unexepted shutdown, it's possible that the index is corrupted and you have to reindex....

we had that problem too in production, after six month we switched to linux

wich version are you using?

It worked! Thank you very much, my friend!

However, we'll also consider the linux environment before moving to production, if it's more stable.

Bye!
