Hi Nicholas,

 

Looks like Note 2092033 is not released.

 

All checks have same output except the view of STATISTICS_LAST_CHECKS > ALERT_LAST_CHECK_TIMESTAMP has a new entry with recent timestamp.statistics_view.PNG

Raj

Sytax is: CE_CALC(‘<expr>’,<result_type>) ;   ..like your defining an actual calculated column, so you need type...system haveto CAST expressions result into some type.

 

Example:

CE_CALC(‘”SALES” * :vat_rate’, decimal(10,2)) AS “SALES_VAT”


Hope it helps

Hi Vivek,

 

"_SYS_BIC - As explained above all Column Views are stored here". Not only column views, even other activated objects like procedures, table types etc will be stored in BIC.

 

_sys_rt - It also contains configurations related to table partitioning.

The version of UAFL that was recently released (1.301.0) now contains an "aflundeploy"  executable that can be used to uninsall the UAFL plugin.

See SAP Note 2103854 for instructions.

Re: TABLE_COLUMNS COMPRESSION_TYPE wrong documentation?

NONE is indeed related to all non-column store tables columns, since SAP HANA compresses only column store tables. So NONE would be also present for virtual tables or dynamic tiering tables.

 

The general TABLES/COLUMNS system views typically contains detail attributes that are only valid for specific table types.

 

But, sure enough, there's a gap in the documentation on this.

HANA does not start: "serviceType mismatch"

$

Hi all,

 

When I try to start HANA (rev. 85) the nameserver_alert trace file says  "serviceType mismatch" and the daemon trace file says
"

Failed to retrieve HA role for current host from topology, cannot proceed with startup sequence.

Please make sure to properly add additional hosts using addHost/hdbnsutil

"

 

My system is however single node. It was being used as secondary in a system replication but I deregistered that.

 

I tried everything I can think of (even restart the server ) but no success.

 

Anybody with some idea..?

 

Thanks!

 

 

 

 

PS. Here is some more outputs from the nameserver_alert trace file:

Hi Christian, You mentioned it was a secondary HANA instance on a SINGLE HOST SYSTEM before it was deregistered.  Can you please the nameserver.ini file under the below path on the Secondary host under: /hana/shared/SID/global/hdb/custom/config [landscape] id = 76183046-abdc-3w24-d230-0000a1109ae7 master = *NODENAME*:30001 idsr = 5413c002-7632-b615-e100-0000b7609b20 You should not see any entries for the Replication ID if it was properly deregistered from the System Replication. It will confirm that the Replication is not causing the issue


Re: HANA parameter setting

For those who can't get it work,

try making different names of input parameters

in a Caller and Called procedure/calc view.

 

In my case, I was trying to pass my IP_TARGET_CCY

from Parent calc view to Child calc view,

but Child always took its own default value.

 

Only different naming helped.

Ok, gut feeling tells me that there is a kind of session timeout kicking out your statistics server session after some time.

 

I recommend to migrate the statistics server to the embedded statistics service and avoid this problem altogether.

Hello,

 

Can you please attach the below output of GPFS filesystem commands:

  • to see which fileset is affected: "mmrepquota --block-size G -a"
  • to get the (fileset > mountpoint) correspondence : "mmlsfileset sapmntdata"
  • to see which disks belong to storage pool hddpool: "mmdf sapmntdata --block-size G"

sr_state does not fnd any left over entries for System Replication so we should be clean

Can you try taking a new backup from the source HANA system and recover it on the Secondary system? Looks like the current backup does not work

Re: Shutting down correctly Hana Server SAP Business One

Dear Jacobo,


I found the answer to your question in SAP Note 1969397 on "Troubleshooting Guide for SAP Business One, version for SAP HANA". There it says:

4.1 Question: What commands should I use to restart SAP HANA and the various SAP Business services? And in what sequence?

 

Solution: Restart the SAP HANA instance and the services in the following order:

      1. Restart SAP HANA instance as the <sid>adm user (e.g. ndbadm):
        1. Stop the SAP HANA database: ./HDB stop
        2. Start the SAP HANA database: ./HDB start
      2. As a root user:

< 9.0 PL11:

        1. Restart the server tools (SLD, license, and mailer): /etc/init.d/sapb1servertools restart
        2. Restart the analytics service as below:
          1. Stop the service: /etc/init.d/b1ad stop
          2. Start the service after a few moments to ensure tomcat has been stopped: /etc/init.d/b1ad start

>= 9.0 PL11: Restart the server tools and the analytics server using the same command: /etc/init.d/sapb1servertools restart

 

What HANA is concerned, instead of "./HDB stop" you could also use the corresponding sapcontrol command:

 

saposcontrol –nr [Instance Number] –function StartSystem/StopSystem/RestartSystem

 

However for B1 application specific questions (how to assure that no users are logged on into the system) please reach out to the experts in the SAP Business One SCN forum:

http://scn.sap.com/community/business-one

 

Best regards,

Michael

Hello Safiyu,

in what kind of requests have you made the observation that analytical views are faster than calculation views? I am just curious because I had the impression that calc. views are much faster.

 

Especialy if you use the SQLEngine.

Venu,

 

I will suggest to go with calculation view with star join.

 

You can create calculation view as dimension for these tables: - PROJ,PRPS,SKA1,T001,CEPC,CEPCT

 

Then you can create calculation view with star join by including transaction table COEP,COSP,COSS  as your base. Aggregate, join your data based on your requirement and then simply use above calc dim views in star join node.

 

Advantages: -

  • You need not to define multiple analytical view for each fact table
  • SAP is putting lot of effort in enhancing calculation models, so from long term solution perspective this is best choice.
  • Star Join works well in terms of performance.
  • You can consume this model either in BW as virtual provider or you can push data to BW target through ODP .

 

Link on how to use Calc view with star join : -

 

HANA SP07 - STAR JOIN

 

I am currently working on SP8 and these views works really well .

 

Regards,

Kulwinder
