Re: Problem with HANA System Replication Configuration
Hi Sergio Gonzalez Hitachi
Have you tried a netstat from the primary server "SITEA"?
nestat -na | grep <ip_SITEB>
it is not showing anything
but telnet and ping is working fine.

Re: How lot take log backup using script in HANA
Hi Rahaman,
Yes, it is because log_mode paramater. it should be NORMAL. And yes, Recovery of PIT(Point in time) will not be possible. But, however, you can make recovery of the HANA DB by using existing data backup only.

Re: Hana Backup Catalog
HI Joy,
in order to solve you issue you need to take the restart of the nameserver service. I have seen this issue in revesion 74 and the same has been corrected in revision 80.

Re: String to Hex , remove all special characters and back to String again
Hi Reddy,
Anyways, you can create a calculated column to convert string to hex using rawtohex('String') function and unhex it back with hextoraw('hex_string').
Hope it helps.

HANA High Availability in Scale-Out
I understand one of the HA solution for single-node / scale-up installations HANA is HANA System Replication. For Scale-Out installations, one or more standby node(s) do provides some level of HA (via the Host-Auto Failover method), however it does not provide protection from multiple failures. Some possible extreme designs might be to:
- Add a standby node after every 'n' nodes (where n<=2).This I believe can be accomplished using the host group concept in HANA.
- Create a complete isolated 'n' to 'n' HA system, i.e. if primary has 4 nodes, create another 4 nodes of secondary system and setup system replication. This feels like an expensive solution for HA (maybe okay for DR).
Please note: I am ignoring the disk based replication and recovery on purpose because the scope is truly HA where quick system availability after an incidence is most important. That certainly again feels like a good option for DR.
Now coming to the question:
Can someone share any insights on how you have setup HA for your scale-out systems? What do you like about it and what you think is difficult to operate with it?

Change SIDADM name
Hello Team,
we have SAP HANA SPS9 with multitenency configured. Now say the tenant DB SID is DHI(this is the default DB that got converted to tenant) so the SIDADM name is DHIADM but we want to rename that user to PHIADM.
Is it possible? if yes what is the step by step procedure?
Thank You,
Amol

Re: Repeat a failed transport
Thanks Tarun
You make it sound as though there is a way to "capture a change". I am not aware of that functionality. The only way to "collect or capture" the objects, that were in my previous transport of changes, seem to be to actually "touch" and reactivate each object again.
Would you agree with the above?

Re: HANA Date and Time Comparison
I think this is a good way of doing it:
IF(YEAR(:v_end_time)+DAYOFYEAR(:v_end_time) < YEAR(:v_start_time)+DAYOFYEAR(:v_start_time)) THEN
SIGNAL CUSTOM_EXCEPTION SET MESSAGE_TEXT = 'End datetime should be MORE RECENT than Start datetime.';
END IF;

memory_size in sys.m_expensive_statements
Was wondering what the memory_size is in sys.m_expensive_statements.
I'm see some memory values like: 337,340,294,412. Is that terabytes, but that seems too large.

Re: Problem with HANA System Replication Configuration
Hi Hitachi,
finally it is working,
Issue:
statisticsserver is embedded @ primary site.
hostname is having same name in the both hosts.
solution:
make the target side also embedded statsserver
change the hostname on target side
then issue is resolved.
thank you for your response

Re: memory_size in sys.m_expensive_statements
Hi Mike
The unit of measurement is bytes, so 337,340,294,412 bytes is around 3.37 GB.
