Hello:

 Last Saturday we've upgrade our production lpar to z/OS 1.10. Since last 
saturday when we enter the netstat home command we received this output:

EZZ2350I MVS TCP/IP NETSTAT CS V1R10       TCPIP Name: TCPIP
EZZ2698I -- reserved for future use --

EZZ2700I Home address list:

EZZ2701I Address          Link             Flg 


All fields are empty. In our development LPAR works fine in z/OS 1.10.

We've revised:

1 .- The RESOLVER config: This is our RESOLVER proc:

//RESOLVER PROC PARMS='CTRACE(CTIRES00)'                       
//EZBREINI EXEC PGM=EZBREINI,REGION=0M,TIME=1440,PARM=&PARMS   
//SETUP   DD DSN=SYS2.TCPIP.TCPPARMS(RESOLC&SYSCLONE),DISP=SHR 

2 .- Content of RESOLCVR

DOMAINORIGIN  ES.MAPFRE.NET
SEARCH ES.MAPFRE.NET       
SEARCH DES000.MAPFRE.NET   
SEARCH DES007.MAPFRE.NET   

These are our business DNS. We can entered a ping to the first IP in HOME  
PROFILE.  

3 .- Our etc/hosts has the correct IP (the same than HOME in PROFILE)

4 .- We are searching too the netmsg.cat in /usr/lpp/tcpip.... because 
appears in some links. This file is identical between our production lpar and 
development lpar

5.- In production lpar we enter the comand D TCPIP,TCPIP,NETSTAT,CON the 
system respond:

D TCPIP,TCPIP,NETSTAT,CON           
EZZ2500I NETSTAT CS V1R10 TCPIP 211

6 .- In development lpar we enter the same command:

ro vdes,D TCPIP,TCPIP,NETSTAT,CON                                       
EZZ2500I NETSTAT CS V1R10 TCPIP 711                                     
USER ID  CONN     LOCAL SOCKET           FOREIGN SOCKET         STATE

CICSTD02 0000E549 10.255.224.212..4112   0.0.0.0..0             LISTEN  
CICSTI01 0000E4CA 10.255.224.212..4121   0.0.0.0..0             LISTEN  
CICSTI02 0000E4CC 10.255.224.212..4122   0.0.0.0..0             LISTEN  
CICSTN01 0000E4C8 10.255.224.212..4151   0.0.0.0..0             LISTEN  

7 .- We haven't change the profile in the upgrade to z/OS 1.10 in both lpar. 

8 .- When the DB2 master starts, it appears the message:
23.29.37 STC06383  DSNL512I  %DSNR DSNLILNR TCP/IP  985                 
   985             GETHOSTBYADDR(10.255.224.222) FAILED WITH            
   985                        RETURN CODE=1 AND REASON CODE=00000000    
 
 10.255.224.222 is he first IP in HOME profile. Could be connect both 
messages (netstat and gethostbyaddr)?

The z/OS communication server works fine in both lpar, except the problems 
above.
