Been the sme and completely architected and implemented the entire middleware server farm for my last company. First in ibm after taking it over from someone else that started it, just a here you go takeover. Then moving from an ibm shop to oracle, cause the vp wanted a gold star and wouldn’t listen to anyone. I left when they were moving to red hat when the next vp came in and wanted their gold star. Little over 400 servers. Been there done that.
