Theses servers are a specialized version of ARTSTRN servers presenting only transactions with MAXACTIVE = 1; While ARTSTRN servers present only transactions with MAXACTIVE > 1.

It is critical and verified by STR1 servers at boot time that MIN and MAX number of servers are set to 1. The goal of these servers being to guarantee the parallel processing of only one transaction in a group (with MAXACTIVE = 1), to start or let Tuxedo start a few servers offering the same transactions will be self-defeating for STR1 Servers.

Since MIN and MAX are set to 1 the Tuxedo argument RQADDR, become unnecessary, and must be avoided for simplicity.

The rest of the configuration and behavior of STR1 servers are exactly the same a STRN servers.
