Tuxedo tpcall() Via Tuxedo's Domain Protocol Gets Slow Response If Remote Domain Is Not Available

(Doc ID 1615074.1)

Last updated on AUGUST 29, 2017

Applies to:

Oracle Tuxedo - Version 6.4 and later
Oracle Solaris on SPARC (64-bit)
Oracle Solaris on SPARC (32-bit)

Symptoms

Tuxedo domains on Solaris having many(over 40) remote Tuxedo access points  defined with Tuxedo ON_DEMAND connection policy configured (in Tuxedo domain configuration file).
The client domains sending a tpcall(), including WebLogic Tuxedo Connector ones,  seem to depend on the platform's operating system(also known as OS) configuration.

Usually, if a remote Tuxedo GWTDOMAIN process is not up(but OS is booted) , a Tuxedo tpcall() will get TPESVCERR immediately. If over 40 tpcall() occur, per each domain accesspoint call at the same time, some calls have a resulting delay of 3 seconds.
