SCM WP trace file error message

[Former Member]

Hi,

We are getting the below error in our work process trace files for our SCM 5.1 system

Tue Dec 30 17:35:51 2008

***LOG Q0I=> NiPGetHostByName: hostname 'OPTSERVER' not found: gethostbyname [niuxi.c 1470]

At same time, we have system log entries as below:

19:07:34 BTC 031 009 APOADMIN Q0 I Operating system call gethostbyname failed (error no. 0 )

Documentation for system log message Q0 I :

The specified operating system call was returned with an error.

For communication calls (receive, send, etc) often the cause of errors

are network problems.

It could also be a configuration problem at operating system level.

(file cannot be opened, no space in the file system etc.).

Does anyone know about this?? The RFC connections between APO server and Optimizer server are working fine and there is no issue. However, for any dialog/background process we are getting the error above. Please suggest.

Regards,

Sandeep.

Dear Sandeep,

The "Operating system call gethostbyname failed" only occurs if the target host is located in a different DNS domain than the sending machine and load distribution is activated in transaction SM59 for the relevant destination.

To fix this error you may need to apply the latest kernel patch to Your system, Please take a look at note 821661 for details.

Hi Tibor,

Thanks for your reply. However note 812661 is not relevant for our system as it is SAP_BASIS 700 level 14 while the note is for SAP_BASIS46D 620 and 640 kernels.

Please advice.

Hi Senthil,

Thanks for your reply. As in the note 388193 that you have mentioned job /SAPAPO/OM_REORG_DAILY is executed daily in our system and there does not seem to be any issue with optimizer installation as optimizer is working fine and there is no connection problem with scm system.

However the SM21 errors keeps coming.
