Abstract

OSP-OTHER-INCORROUT TRCTCPAPP APP(*HTTP) WITH SYSTEM VALUE
QALWUSRDMN SET TO FILEACCESS CAUSES HTTP SERVER CRASH.

Error Description

TRCTCPAPP APP(*HTTP) with system value QALWUSRDMN set to        
FILEACCESS causes HTTP server crash. The HTTP server job        
receives a SIGKILL or SIGABRT                                  
                                                               
When the TRCTCPAPP command is entered, HTTP server code creates
user queue (*USRQ) QUSRSYS/QZSRHTTPTR. If this sysval          
QALWUSRDMN is set to only have library FILEACCESS , the user    
queue QZSRHTTPTR will fail to be created in library QUSRSYS or  
the ENQ MI instruction fail to run. This the reason why we see  
the ENQ fails.                                                  

Problem Summary

TRCTCPAPP APP(*HTTP) with system value QALWUSRDMN set to        
FILEACCESS causes HTTP server crash. The HTTP server job        
receives a SIGKILL or SIGABRT

MI instruction fail to run. This the reason why we see the ENQ  
fails.                                                          

Problem Conclusion

The ptf is to avoid HTTP program crash by failing the trace    
enablement if the sysval QALWUSRDMN does not allow creating    
temporary objects in library QUSRSYS.
