Installation Prerequisites on Microsoft Windows Here are the installation prerequisites on Microsoft Windows. Supported Platforms See the TIBCO Administrator readme file for details about the supported windows platforms. Prerequisite Software See the TIBCO Administrator readme file for details about software requirements. Installer Account You must have administrator privileges on the machine on which TIBCO Administrator software is installed. Installing from Networked Drive If you intend to install the product on a networked drive, you must change the user in the Services Configuration from Local System to a user that has permission to access the networked drive. Memory Requirements for the Administration Server The machine on which the Administration Server is installed should have a minimum of 2 GB of system memory. The heap size set in tibcoadmin_domain.tra (java.heap.size.max=512m) is set for a machine with 1GB of memory. If you have less memory, we recommend lowering the heap size. The idea is to have the (heap size) + (memory required by the operating system) < the memory of the machine. For example on Microsoft Windows, if you have 512MB of system memory, set the heap size to no more than 300MB because Windows itself requires about 200MB. Required Disk Space The TIBCO_HOME directory must at least have 250 MB of free disk space.
