If the plan includes buying new hardware, consider migrating to 64 bit Linux. Linux is the primary development platform for EBS.

  • Release 11.5.10.2 doesn’t support running the Application Tier on a 64-bit hardware platform; however, Release 12 does support 64-bit architectures for the Application Tier.
  • Release 12.1 and Release 12.2 all support running the database on a 64-bit operating system, in a split or mixed architecture.
  • There are five hardware platforms supported for Release 12.1 and all of the platforms support a 64 bit version.
  • There are less memory restrictions on a 64-bit machine because of additional addressable memory.
  • Because of more addressable memory, more users can be supported on each Application Tier.
  • MRP and other programs run much more quickly in a 64-bit database.
