What would cause TSS7150A SPECIFY PASSWORD FOR STC=  message?
 

Release:
Component: TSSMVS

There are 2 common instances of the TSS7150A prompt with a started task. 
First, if the TSS7150A message is issued at startup, if the started 
task acid has a password, make sure OPTIONS(4) is set in the TSS parmfile. 
We recommend that all started task (STC) acids be given a password and 
OPTIONS(4) be set in the TSS parameter file. OPTIONS(4) will eliminate the 
prompt for a password when the STC starts, but if someone tries to signon 
with the STC acid, he will need to know the password. 

The other instance is the TSS7150A is issued when a user trying to 
signon to the application enters the wrong password. In this case 
the started task acid needs a MASTFAC added to it pointing to the 
facility you want used for the application: 
TSS ADD(stcacid) MASTFAC(facname) 
The 'facname' should be the name of the facility they want associated 
with the started task. This facility will then need to be added to 
the users that signon, an attached profile, or the ALL record if everyone 
should be allowed access (TSS ADD(acid) FAC(facname).) You can either 
setup your own facility (rename a USERnn facility currently not being used) 
or use an existing facility. You will need to recycle the started 
task to pick up the MASTFAC.
