disp+work state=YELLOW, reason=Request handling without progress

[former_member190996]

Hi,

The below is my setup:

OS: SUSE Linux 12 SP13

DB: HANA 2.0

Below are the details of the disp+work of which I have updated from patch 17 to 301:

The DB has been up and running successfully. But the S4HANA 1610 IDES which is a new single host installation, the dispatcher is always YELLOW and says Request handling without progress. Below are the errors from dev_disp:

I have gone through several posts on he SCN, and mostly recommend patching the kernel which I did with no luck. Let me know what else am I missing here.

Thank you.

Can you please also paste the dev_ms?

[former_member190996]

Thanks for the reply. dev_ms is attached.

I see the below errors:

*** ERROR => MsSCheckConnections: no response from client C2 (127.0.0.1) after 300 secs received [msxxserv.c 4725]
*** ERROR => MsSCheckConnections: disconnect now [127.0.0.1] [msxxserv.c 4729]

I see it's trying to connect to 127.0.0.1, where as the host is mapped with 192.168.xxxx in the hosts file? How can I fix this?

Hello,

I couldn't identify a single reason why your instance is not starting, however, I have some ideas.

1) Did you introduce any other changes besides the kernel upgrade? Any modified profile parameters?

2) Ping your hostname and check the IP

3) Did you change the hostname or IP address of this system?

4) What about memory? Is HANADB installed and running on the same host? How big is the swap space? Try running free -g and check the available memory

5) Did you read the folowing note?

1984787 - SUSE LINUX Enterprise Server 12: Installation notes

[former_member190996]

1. No changes were done besides the kernel upgrade.

2. When I ping the hostname, I get the response from the IP (192.168.xx.xx) which I have maintained in the hosts file.

3. No changes are done to the hostname and it's IP.

4. The memory of this virtual machine is 120 GB. Yes, DB installed and running successfully. Swap is 80GB.

5. I have checked the note and implemented few of them about UUIDD.

Can you try to add to the instance profile parameter (do the backup first):

PHYS_MEMSIZE = 16384

And then restart the instance.
