3.4.2 Initiating IIOP Client Failover

To initiate IIOP client failover support, ISL servers must be specified using the -C warn|none option in the *SERVERS section of the UBBCONFIG file

This option allows ISL to accept unofficial connection directly from the client orb. ISL servers that are not specified using the -C warn|none option will not be placed in candidate IIOP gateway pools. Consequently, the client will not failover to those ISL servers.

In the following UBBCONFIG file code snippet, the ISL servers specified in lines 1 and 2 must support client failover. The ISL server in line 3 will not.

*SERVERS
ISL SRVGRP=SYS_GRP1 SRVID=10 CLOPT="-A -- -C warn -n //myhost1:2468"
ISL SRVGRP=SYS_GRP2 SRVID=20 CLOPT="-A -- -C none -n //myhost2:2469"
ISL SRVGRP=SYS_GRP3 SRVID=30 CLOPT="-A -- -n //myhost3:2470"
