Dispatcher hangs in windows 2008 server

[former_member210781]

Hello there,

We have distributed environment for SAP NW 7.3 installed Application Server as ABAP .SAP CI is on windows and Database is oracle11g and it is on AIX.

Our database and CI installed successfully w/o any error.

When we have tried to start SAP CI , Message server,dispatcher and Enque turns green and after 10mis dispatcher hangs and turns to yellow.We have checked in WP process table it shows status of work process as" New " and semaphore column it shows as -10.

Our R3trans o/p is 000 , as well as R3trans -x o/p 000

Also from Database host( which is on AIX) we are able to telnet SAP APPS host( which is on windows) on port 3201,3301,3601 ( 01 is system number). We are able to ping database host from SAP APPS and APPS from database.

Our kernel version is 721_EXT_REL , patch no 30 , on AIX  version is 1 6.

One thing is our SAP Application server and Database is in different subnet .Not sure if this is causing the issue...

Does any one has encountered similar issue earlier ....any suggestion are warmly welcome...

Hello Guys,

The Problem is resolved.. What we have done is we have bring Database in the same subnet where APPs and CI are placed.

Hmm,

some things that do not get together...

You say you have instance 01, but dev_disp is connecting to the message server at

msserv:   >3900<

This indicates a seperate central services instance, which would explain why you see

a seperate ENQ service in the instance manager and dev_disp is indicating

wp_no_enq:  0

So I do not understand how you message server can reply on the public port 3601

when ASCS should be running on instance 00.

It should be 3600 unless you changed somthing manually.

So please clearify what your setup is like.

Check and/or attach dev_ms (may be from teh other instance directory) in addition

and may be all of the SAP instance profile.

Hi,

    Please attach the dev_disp , dev_wo log files for more analysis. these files will be available in /usr/sap/SID/DV*/work

Please make sure that the kernel level is same in all the two locations.

/sapmnt/SID/exe

/usr/sap/DV*/exe

Thanks and Regards,

Hi,

It seems that due to below output from your dev_disp.

NiHLGetNodeAddr: hostname 'www.doesnotexist0066.qqq.nxst' not found by operating system

***LOG GZZ=> 1 possible network problems detected - check tracefile and adjust the DNS settings [dpxxtool2.c  6437]

Please request your Network team to check .

Make sure that CI & DB & APPS are able to communicate between each other.

Maintain the host entries for all the three systems on all these three systems.

Please check and provide your feedback.

Thanks and Regards,

Hi Rasesh,

Have you configured SAMBA to share the /sapmnt/<SID>profile to Windows server ??

If not, you need to do this so that application server reads all the relevant information required and connects to correct system.

Hello Deepak,

Yes we have SAMBA and DB can read profiles from APPS windows host.

Files you uploaded have different timestamps:

Please upload synchronous versions.
