We changed the way to start the EntireX RPC Servers on the mainframe.

Instead of starting 5 RPC Server jobs, we now start only one job containing 5 tasks (NTASKS=5) and set trace to 1 (TRACE=1). And we also switched from SVC to TCP/IP.

Task 1 (CMPRT10) traces everything.

But tasks 2-5, (CMPRINT1-4) receive the error message:  
Error during RPC trace, trace switched off now  
Error 1520 line 2070 NATSRVT  
Error during RPC trace, trace switched off now

With NTASKS \> 1 the handling of CMPRTnn files is a bit different, see

Wolfgang,

This is now my updated JCL:

//RPCSRV EXEC NAT42,DEPT=ST,DB=DEVL,TIME=100,

//CMPRINT3 DD SYSOUT=\* OUTPUT OF SUBTASK 3

SRVUSER=’\*NSC’,SRVNAME=STDEVT2,MAXBUFF=4992,NTASKS=5,TRACE=1)  
//

I don’t know where the TRACE1 statement comes from?

It also seems to me that the ouput of CMPRINT cuts off the parm values after NT.  
…SRVUSER=‘\*NSC’,SRVNAME=STDEVT2,MAXBUFF=4992,NT

Thank you.  
Dieter

1. 

The TRACE1 file is required if a stublog of the EntireX Broker stub should be written (for the first subtask). Use TRACE2, TRACE3,… for additional subtasks.  
2)  
The contents of one RPC=(…) string is limited to one print line. To see all RPC subparameters use several RPC=…) strings, for example:  
RPC=(SERVER=ON,RPCSIZE=5000,ACIVERS=4,LOGONRQ=ON),  
RPC=(SRVNODE=‘xxx.187.32.2:18235:TCP’),  
RPC=(SRVUSER=‘\*NSC’,SRVNAME=STDEVT2),  
RPC=(MAXBUFF=4992,NTASKS=5,TRACE=1)
