Look, I don't know you, but I'm sure nobody here is casting any aspersions on your skill set. It's just that installing and implementing an ERP package is generally a highly complex technical operation, and going in without either training or guidance is a recipe for a half-assed implementation.
I've just reviewed all your posts, and nowhere have you ever explicitly mentioned what you are running on. I have to infer from several different posts that you are attempting to run E1 9.0 with a local Oracle database on the Deployment Server, RHEL on your Enterprise Server, and OAS as your JAS server. There is no mention of what your database is. It helps to have that specific information to be able to help you.
Open, general questions are not in the spirit of what JDEList people will usually help out with. There is simply too much information to convey, in a limited space, that a person who has either had some training or read the appropriate manuals should not be asking. To me, this feels like I would be trying to train you (and by extension everybody who reads JDEList) for free.
As you might expect, many of us here, including me, are trying to make a living with the knowledge of how to do these things you ask. This knowledge was only gained through years of training and experience ... at least it took me a year of classes, trying things in the lab, and shadowing my boss at live installations before I felt I truly understood the nuances of what the heck was going on with the technical side of things.
This is why your questions on installation tend to be met with a "hire someone" or "take classes" response, because such open-ended requests for help are best answered that way. Either that or reading the manuals and spending many weeks at the task. As you say, you have spent much hard work to get to this point. This is the tradeoff your employer has had to make. Your boss has decided he would rather spend your time and effort, rather than spend some money to either send you to a class or have someone come in to teach you properly. (Which I generally do. Whenever I am at a client, there is usually someone who is watching what I do so I can pass along the knowledge to someone at the client. They have paid for my time, after all.)
The results of this will generally show in that you are likely not even aware of what you may be missing. For instance, you had a couple of questions of how to "translate" JDE. The simple answer to this was to download or order the CD image of the language you wish to use, and follow the appropriate steps in the installation manual. You had also asked how you add a 2nd Enterprise Server. This too is in the installation manual, which you must have read to get this far.
Don't get me wrong. If you have a specific question, it would generally be answered to the best of someone's knowledge. JDE is a complex product which is extremely flexible in its configuration, but also extremely difficult to completely understand because of that flexibility. Open-ended questions like how to install a database instance just don't elicit much response. Because you haven't specified what database you use, how can we tell you to install an instance of one of 5 possible databases on one of 8 possible platforms (well, in your case, 2 possible databases)? Pinned at the top of every forum listing is "How to Ask Questions the Smart Way." Please start with that. If you can make your future requests for help more specific, then I'm sure you'd get better answers to your questions. After all, I've been at this for a dozen years now, and people like altquark, Brother of Karamazov, and cdawes have been doing this for longer, and we all ask questions here sometimes.
