frontendServer memory configuration (increase size more than XLarge Sizing)
We are having some issues related with the frontend memory. We have the XLarge sizing configured but it is not enough. Could anyone tell us how we can increase the memory for this process? We think that it should be defined in some configuration file, but we don not know where and what we have to modify.
Hello Juan,
The file you are referring to is called "dtfrontendserver.ini". Yet I would STRONGLY recommend to open a ticket and discuss this with support before you modify the settings, just to make sure you are taking the right course of action.
Regards
Hello Santiago,
In the file you told us, we found the following content. We had already tried to modify it by adding the "-memory" parameter as it said, but it did not work.
Could you tell us the parameter format that we should use? It would be great if you could provide us an example.
[uwassrv@lep1dna1 dynatrace-6.0.0]$ cat dtfrontendserver.ini

Thank you so much
By any chance, are you running on haswell G9 servers? If yes, there is a kernel patch which makes DT server really fast.
