Gateway monitor is deactivated in SMGW

[ganimede_dignan]

Hi,

a NW04s system on Windows with MSCS (Microsoft Cluster). From few days SMGW tcode returns an error message:

"Gateway monitor is deactivated"

If we run gwmon outside the istance (from Windows command line from on node, as example), gateway should works because we can see any connection.

gw/monitor = 1

Have you got any idea ?

Regards.

Hi,

Please check the OSS note: 915026,

Did you try restarting the gateway process? this hould help in resolving the issue.

Hope this helps.

Hi,

Can you please check the errors you are getting in the dev_rd log in the work directory,

also check in the dev_rd.old.

Please also check the dev_disp i.e dispatcher log for further details.

Regards,

Vijay.

[ganimede_dignan]

Same error already posted.

regards.

A test:

node1 is the hostname of first cluster node (live with db + central istance), node2 is the name of second cluster node (dialog istance)

On console I try some test with gwmon...

node1:

gwmon -gwhost localhost -gwserv sapgw10

OK

gwmon -gwhost node1 -gwserv sapgw10

GwMonDisplayConnTbl2 failed, rc=GW_MONITOR_DISABLED

Gateway monitoring for node1 / sapgw10 disabled

node2:

gwmon -gwhost localhost -gwserv sapgw10

OK

gwmon -gwhost node2 -gwserv sapgw10

GwMonDisplayConnTbl2 failed, rc=GW_MONITOR_DISABLED

Gateway monitoring for node2 / sapgw10 disabled

We have got other MSCS with CRM (ABAP-only) where for each node gwmon on localhost/hostname are OK.

So I try to set gw/monitor = 2 (previus value was 1) on each istance, after istance restart SMGW works .... but I don't be able to explain the cause because in other MSCS system gw/monitor = 1 and SMGW works fine.

Regards.

Hi,

I solved to remove istance param "SAPLOCALHOSTFULL" that was virtual-host-name of cluster.

To anyone out there reading this, please be aware that setting gw/monitor to 2 means that you can run gwmon.exe even on your own PC given firewall access. Perhaps not the best option.

Notes like 129997 should be followed instead. gw/monitor=1 should work from the transaction level or you have a host name resolution issue of some type

[Former Member]

You need to make sure

SAPLOCALHOSTFULL = localhost (Do not enter name of local host your entry shd be localhost

SAPLOCALHOST = <Logical host name> (You need to eneter logical hostname)

Cheers !
