note 1249472 - RCCF: High number of trace files or GetHostByName errors should resolve the issue.

[Former Member · Accepted solution]

Can you attach full log file? According to snippet you have provided the system can't resolve o10n host. Make sure that you can resolve it through DNS or hosts file.

Hi Roman,

Thank you for thought about dev_ file. I fixed my problem! The problem was in SAP APO where was wrong rfc destinations. I disabled an optimizations in  /n/SAPAPO/COPT01 because we don't use it.

[former_member707681]

you can check the note : 2465666.

[former_member182657]

Hi Igor,

Please share the output of command niping -v -S sapms<SID> on IP 192.0.0.86,logs which you posted earlier.

Other which i want to confirm from you about the kernel release on all your landscape servers.Have you tried with kernel upgrade(Please do kernel upgrade on one of your test server).

I suggest you to kindly share this issue with your network team as well as raise a support ticket with Redhat OS.(it seems missing of some packages or need update of glibc package)

Thanks,

Gaurav

[former_member187565]

Hi Igor,

It seems your OS was unable to perform DNS related action in your environment. Please raise a issue with your DNS, Network team to resolve this issue.

[former_member182657]

Hi Igor,

Thanks for the info.As per output of command niping -v -S sapms<SID> provided by you i analyzed host IP is not matching with the IP which we've under /etc/hosts file.

In /etc/hosts your system IP is 192.0.0.86 ewm-qas   but with output of

niping -v -S sapms<SID>  IP is showing 192.0.0.85 ewm-qas.

So here we get one finding regarding the issue.I suggest you to please get info or set only one IP for your hostname to resolve it proper also with niping -v -S sapms<SID> command.

Hope you can understand my point.

Please correct if 'm wrong here.

Thanks

[Former Member]

Hi Gaurav,

No, it's my fault. This problem is on whole landscape, so I paste an information from other server where this error exists too.

[Former Member]

can you please attach the logs from the respective work process (for ex dev_w0)...

[former_member182657]

Hi Igor,

From when you're facing this issue,any recent changes at OS level or any kernel version upgrade etc.

Please share your SAP kernel release & I also recommend you to first update kernel with the latest available as per your SAP release & share further details with us.

Thanks,

Gaurav

[Former Member]

There was no kernel upgrade

[former_member182657]

Hi Igor,

Provide the output for command

Hi Igor,

Kindly refer SAP Note  1249472 - RCCF: High number of trace files or GetHostByName errors

896973 - Service 'xyz' unknown; error in getservbyname/getaddrinfo

Please share entries from /etc/services also.

From note 896973 i found

1) Unix

You can configure the operating system to check whether the lookup for a service name is performed locally and/or using a global service. Some platforms use the configuration file '/etc/nsswitch.conf' for this. Information is also available on 'man services'.

You can locally save service names in the file '/etc/services' with the following format:

<service name>   <service number>/<protocol>   [<service aliases> ...]

For the SAP service names, one entry for the TCP protocol is sufficient. Example if the 'sapmsOss' service name corresponds to port number 3616:

sapmsOSS       3616/tcp

You can use the following command to check whether a service name is stored in the NIS:

:/> ypcat services | grep <service name>

Thanks

[former_member182657]

Hi Igor,

If possible share entry details under files

/etc/hosts,

/etc/nsswitch.conf

/etc/resolv.conf

Please confirm entry 127.0.0.1   localhost.localdomain  localhost  in your host file.It should be like as below:

127.0.0.1   localhost localhost.localdomain localhost

192.168.x.x <hostname>

Hi,

Thanks for the info.Please do the following.

1.Stop your sap instance .

2.Copy or backup of file hosts,resolv.conf from /etc to somewhere.

3.Change entries under /etc/hosts like

127.0.0.1 localhost.localdomain  localhost

192.0.0.86  <hostname> <fdqnname>

:wq!

4.Comment both DNS entries under /etc/resolv.conf & save.

5..Share rpm info of glibc by command rpm -qa glibc,if possible do command yum update glibc for updating glibc pacakage.

Gaurav

Hi,

Please re ensure correct IP address with hostname mentioned under /etc/hosts file for resolving ip with hostname.

Are you able to resolve ip with hostname.

Second kindly confirm about " saposcol " is running at OS or not.

Thanks

[Former Member]

Hi, Gaurav!

Yes I had two records when I run nslookup (by IP address). I deleted wrong record, but this error doesn't disappear. Maybe I should restart the system ?

[former_member182657]

Hi Igor,

Yes .Please do a system restart and revert if you face this issue again.One thing more which i want to point from your screenshot that documentation showing No space left on file system.Please share free space details.

Thanks
