My question is I want to migrate on a LAN environment to 9i or 10g; how do I do it without going into the complications of configuring infrastructure?
The main issue faced by us is iAS configuration. The services will shut down without any specific reason. We applied the right patches but instead of improvement in the configuration we faced more problems. We really don't need the Web-based architecture at the moment but want to move to 9i or 10g. How do we do it?
The other issue moving to iAS is the resources required. We really cannot figure out the hardware requirements, because we noticed that the performance of the applications with just a few forms is dead slow with a configuration of around 2 GB of RAM. Another issue we came across is the report security with HTML reports. Users can move back and make their own changes on the browser and reprint a report, whereas in 6i users had no control on their reports. How do I handle a situation like this?
If we are moving to a Web-based environment how do we go about training our staff, who are new to Java or Web-based tools?
If possible please provide me with details as to what exactly is the hardware configuration required for iAS, if I have, say, an in-house developed financial application alongside other applications, with around 80 to 100 forms and a similar number of reports with 45 to 50 users.
Bottom line, the application server is designed to be spread across multiple small servers and your application determines how well a set of servers handles the load you place on it. The real advantage of the application server is that you can easily add additional middle tiers and the AS will handle the load balancing and fail over.
As far as the minimum hardware configuration, that is explained in the docs, but the minimum hardly ever will handle the load.
