When trying to start the data server, users may see the following error:
'sse 4.2 or later'
This is a known issue with the version of the data server shipped in Appian installations. This version of the data server requires the SSE 4.2 instruction set, which is a flag supported by modern CPUs. Older CPUs or ones that don't support SSE 4.2 will not be able to run the data server by default.
This issue has been reported to the Appian Product Team. The reference number for this issue is AN-105201.
Open a support case with Appian Support to request the non-SSE version of the data server. The zip file provided by Support will contain the q binary and an updated q.k file. Simply replace the existing q binary and q.k file in the appropriate <APPIAN_HOME>/data-server/engine/bin/q/<OS>/ directory.
This article applies to Appian 18.1 and later using a non-SSE enabled CPU.
