Retrieve the System Name

January 28, 2004 Hey, Ted

At the end of reports, I print a special line that indicates that the report is complete. In addition to the message “end of report,” I print the qualified job name, qualified program name, and in the case of SQL programs, the last value of the SQL status variable. These values help me to debug and troubleshoot problems. I’d like to add one more bit of information.

We recently got a new machine with logical partitioning, and we have set up a partition to use as a test environment. I would like to add the system name to the end-of-report line to help me distinguish between reports generated on the two systems.

There are several ways to retrieve the system name.

One method is to create a small CL program that runs the Retrieve Network Attributes (RTVNETA) command and passes the system back to the caller through a parameter.

pgm       parm(&SysName)         

dcl       &SysName    *char     8

rtvneta   sysname(&SysName)  

endpgm                       

Assuming the CL program has the name GETSYSNAME, an RPG caller would look something like this:

Fqsysprt   o    f  132        printer oflind(*inof)             
                                                                
D PrtLine         ds           132                              
D SysName         s              8                              
                                                                
D GetSysName      pr                  extpgm('GETSYSNAME')      
D  SysName                       8a                             
                                                                
D psds           sds                                            
D  psdsProcName           1     10                              
D  psdsLibName           81     90                              
D  psdsJobName          244    253                              
D  psdsUserName         254    263                              
D  psdsJobNbr           264    269                              
                                                                
C                   callp     GetSysName (SysName)              
C                   eval      PrtLine = '* End of report *  ' 
C                             + 'Job(' + psdsJobNbr + '/'       
C                             + %trim(psdsUserName) + '/'    
C                             + %trim(psdsJobName)           
C                             + ')  Program('                
C                             + %trim(psdsLibName) + '/'     
C                             + %trim(psdsProcName)          
C                             + ')  System(' + %trim(SysName)
C                             + ')'                          
C                   write     qsysprt       PrtLine          
C                   eval      *inlr = *on                    

The output of the program shows the system name, as you requested:

* End of report * Job(877501/THOLT/S9) Program(THOLT/E1) System(TS400)

A second method is to use a SQL special register. You may spell the special register CURRENT SERVER or CURRENT_SERVER.

C/exec sql                  
C+     values current server
C+       into :SysName      
C/end-exec
