Running NBX

To start NBX, use the standard TACL RUN command.

NBX can be run from any user ID. The NBX object file must be licensed. Licensing is

required due to a privileged procedure used for user ID verification and dynamic session

process management.

Since NBX performs network protocol functions, it must operate at a relatively high

priority to avoid timeouts and other network problems.

Once the NBX process is started, NBXCOM is used to configure domains and 6530

windows and to adjust parameters.

You can use the following PARAM statements with NBX. (Undefined PARAMs

generate EMS events and are bypassed.)

PARAM BACKUPCPU cpu

specifies the backup processor number. The default is NONE. Refer to BACKUP /

BACKUPCPU on page 3-12 for a description of available options.

PARAM POOL^SIZE number

specifies the size in words of the extended segment memory pool used for control

tables and I/O buffers. The default is 1,000,000 words. number can specify a

decimal number optionally followed by the letter K (kilowords), which multiplies by

1,024, or by the letter M (megawords), which multiplies by 1,048,576.

The NBX pool requirements in words are as follows:

Process startup—90,000 words

ADD DOMAIN—26,000 words

ADD WIN (static or dynamic)—9,000 words

Active session (WIN or WSPTP)—4,300 words

Allowing a 10 percent margin, the default NBX pool size of 1,000,000 will support

61 active 6530 windows or 199 active WSPTP sessions.
