Commands

Syntax

option value[{byte|kbyte|mbyte}]

Supported options:

• ramdisksize
• libstacksize
• taskstacksize
• ifaddr
• sysdatarecfilename
• sysdatareclen

system data recorder length (number of records)

• sysdatarecposttriglen
• haplsstartoutput
• haplsrange
• translatormempartsize

initial size for translator memory partition

• passbuffersize
• ipaddressmask

                Examples: 
	        ipaddressmask 192.168.20.20:255.255.0.0 
                ipaddressmask dhcp 

 

• defaultgw

sets default gateway, available since version 0.4.17.2
Examples:
defaultgw 10.4.20.1 

• netif
• sleep

delay in millesconds

• stringblockpreload

initial size of string descriptors. Default is 300,000. Reduce this value if application has less than 300,000 string variables.
               Set a number of pre-allocated fixed blocks for string management 
               Example: stringblockpreload 200000 
               Rules:
               1. For best performance This number shell be tuned to the maximum number (BlockMallocCounter) of "common shared" strings/structures used by application
               Hints: 
               BlockMallocCounter: maximum ("saturated") number of fixed blocks  
               BlockInuseCounter: number of blocks allocated at this moment

• hpetfreq
• defaultbus
• singlebus
• cantimings
• socandevice
• tcp_keepalive_time

• tcp_keepalive_probes

See Socket_keep-alive_timeouts

Examples:
ipaddressmask 192.168.20.20:255.255.0.0
