The upgrade documentation references the need to run the jive setup command after installing the Jive RPM on a server. You are wondering whether this command has to be executed on each server, or whether it can be safely skipped.
Jive recommends running the jive setup command on all the servers to ensure that any warnings or issues it detects are addressed. This command will identify any issues that may prevent Jive from successfully starting up, for example, the address of the cache server not being specified. By running this command, you will ensure that all the necessary configuration settings for the server are in place.
