HANA Index Server Not Starting

[Former Member]

   Hi,

We are using SAP HANA Rev 48 on AWS. HANA Server got crashes and Index server is not starting.  Looking at Crash Logs (Attached), seems HANA Memory Usage is close to Allocated Memory.

How can we resolve this. We may be fine to unload tables or delete some of the data to make the system up and running but unable to perform actions as for these DB need to start once.

Any suggestions.

Thanks,

S

Hi Shobhit,

If I follow your original message correctly, you are using HANA One Rev 48. Then, if you follow https://scn.sap.com/docs/DOC-59814, you will see HANA One Rev 48 was released on Feb-7-2013 which came with 1 year license. So, your HANA license key delivered via HANA One Rev 48 must have expired now.

There were multiple messages, blogs posted requesting existing HANA One customers to migrate to HANA One Rev 52.1. Here is one such blog:http://www.saphana.com/community/blogs/blog/2013/09/26/sap-hana-one-migration-via-data-backup-and-re.... The blog says -

"SAP released HANA One Rev 38, HANA One Rev 48 and HANA Rev 52 prior to the releasing HANA One Rev 52.1. HANA One Rev 52.1 has self-service upgrade capability via Addon Manager [blog]. Customers using HANA One Rev 52.1 can continuously upgrade to the latest HANA version as a self-service option and can also extend 1 year license key at its expiry or install a valid license key, if needed. However, customers using HANA One prior to HANA One Re 52.1, cannot upgrade HANA nor can extend license key. This blog provides a step by step procedure to migrate older releases of HANA One to the latest HANA One to take advantage of new Addon feature in HANA One Rev 52.1."

It appears you haven't upgraded your HANA version from Rev 48. I believe HANA One Rev 52.1 supports HANA Rev 72 as I write now.

As a good practice for any database, you should take periodic backup to meet your business requirements. I see you don't have backup.

If this is extremely urgent to recover your system, you may contact HANA One team at hanaone@sap.com with valid business justification why you may need a temporary license to recover your system and then you can migrate to the latest HANA version delivered via HANA One.

Thanks,

Swapan Saha

P.S. I have new responsibility at SAP and hence not following HANA One messages regularly. Just responding here due to the uniqueness of the issue. However, community members and my HANA One colleagues are regularly following up here. So, once you resolve HANA License key issue, you can resolve related issues with community support here. Please keep using HANA One and sharing your knowledge wih fellow community members.

Hi Agarwal,

Try doing the following steps and then try giving a HDB start.

hdbcons

>mm gc -f

Once you do a forced garbage collection

clean up memory on the node

"sapcontrol -nr <InstanceNumber> -function Bootstrap"

Then try starting HANA. Let me know if it works.

Thanks

Hi Shobhit,

  Try following.

Login to HANA Server UNIX machine as root. From UNIX command prompt, change userid to hdbadm by typing command

>su - hdbadm

Then at command prompt, 

>HDB stop

This should stop HANA database Server. Then to restart database again

>HDB start

Thanks.
