How do I assure that all XFER updates of Domain Name Server ( DNS ) get through?
A. CNR imposes a maximum limit of ongoing transfers (XFERs) on both the (XFER) server and client sides. The defaults are five parallel outgoing XFERs and three parallel incoming XFERs. If the outgoing limit is reached, the XFER server returns a serv-fail to the XFER request, which explains the secondary log messages. To configure this limit, issue these commands: nrcmd> session set visibility=3 nrcmd> dns set xfer-server-concurrent-limit=some desired number Note: CNR imposes this limit to protect the DNS server from XFER saturation, which could cause it to steal CPU cycles from other activities, such as DNS queries and dynamic DNS ( DDNS ) . Use caution if you choose to increase these limits.
