Yes, it is supported. Please see also this thread. For installation follow the documentation for Solaris. Since Solaris does have only the PaaS OneAgent version, you have to include the preloading of the OneAgent in the execution context as described here. Most likely you need to include it in the startup script, or in the Apache envvars file (not sure if OHS is using it) and also it seems OHS has also its own variable definition methods.
