Preparing the Workstation

Before installing McIDAS-X, verify that the workstation is configured to the specifications listed in the table . Then, complete the tasks below.

Enabling Inter-Process Communication

On AIX, HP-UX, Linux and Solaris systems (i.e., all except Mac OS X), the system administrator should use the command ipcs to verify that your workstation configuration has Inter-Process Communication (IPC) enabled in the system kernel. If IPC is not running, rebuild your system kernel with all IPC functions enabled.

Allocating Sufficient Shared Memory

McIDAS-X uses shared memory for frame allocation. On AIX and HP-UX and systems, the shared memory facility is activated by default and has a sufficient maximum segment size for most McIDAS-X sessions. However, this is not true for Solaris, Linux and Mac OS X systems. The system administrator must force the kernel to activate the shared memory system at boot time and set the maximum segment size to 512 MB or greater the first time McIDAS-X is installed on a Solaris, Linux, or Mac OS X workstation.

Creating the /home link on Mac OS X

Mac OS X systems use /Users instead of /home as on other Unix-based systems. You can create a link from /home to /Users by running the command below.

Type:  sudo ln -s /Users /home
