Tuxedo ISL Server Can Not Boot If Secure Port (-S option) Is The Same As Nonsecure Listener Port (-n option) (Doc ID 1330293.1)

Last updated on MAY 20, 2022

Applies to:

Oracle Tuxedo - Version 10.3.0 and later
Information in this document applies to any platform.


ISL process ALWAYS uses a Listener Port ("-n" option within CLOPT string). By default this Listener Port is not secured.

When configuring ISL parameters with a secure port ("-S" option within CLOPT string) equal to the non-secure port :

ISL SRVID=125 CLOPT="-A -o /home/appdir/log/stdout -e /home/appdir/log/stderr -- -a -z 40 -Z 56 -S port# -n //TuxMachineName:port# -m 1 -M 10 -x 5 -T 30 -C warn"

ISL CAN NOT be started up and reports in ULOG file the following error messages :

165018.TuxMachineName!ISL.xxxx.1.0: 06-14-2011: Tuxedo Version, 32-bit
