SAP HANA DB failed to recover

Hi Experts,
My SAP HANA DB failed to recover by using option "Recover the database to specific data backup".
We only can use this option because we set the log_mode to 'Overwrite'.
The error as below:
RECOVERY RECOVER DATA finished with error 448.
I have confirmed that SAP NOTE 1820553 and 1800724 is not related
Please advise if you have any idea.
Thank you.
Regards,
Por.

The full error message as below:
ERROR RECOVERY RECOVER DATA finished with error: [448] recovery could not be completed, volume 3, reached log position 0, [3020070] Page 0x28b3bbL already allocated.
Thank you.

Hi Johan,
Yes, the downloaded file was corrupted. I checked the file against the checksum and noticed that it didn't match. So I downloaded everything again and this time checked all files and it installed without any issue.
Good luck

This question is not related to the HANA developer center sandboxes - no user can stop/start these systems...
If the issue happened after a failed restore, your database is probably corrupted and cannot be started. Try to restore another backup. You can also try to restore the same backup again, and choose to not replay the log (recover from data files only). You will probably loose some changes, but at least have a consistent state...

Import failed when Import a SBO Database in SAP Hana

Hi all,
When I try to import a SBO database Rev 69 to SAP Hana with Rev 74, I receive this error:
SAP DBTech JDBC: [2048]: column store error: table import failed: [30151] Object not found in the import directory;object=SBOCOMMON:ETL_Sen
I guess that the error not have relationship with different Revs. I imported another DB with this Rev and this work.
The import was done in 2 ways:
Script:
IMPORT DATABASE."*" FROM '<directory>' WITH REPLACE
Click right in Database, Import, select directory, select tables, import...
Does anyone know what can be or the solution??
Thanks
Best regards

Install of SAP HANA Studio Dev Ed v1.00.80 fails with "Could not create the Java Virtual Machine"

Hello,
Scope: JVM error during initial install of SAP HANA Studio Developer Edition v1.00.80, Win86/32bit
Source: installation files pulled from HANA Studio tab at https://hanadeveditionsapicl.hana.ondemand.com/hanadevedition/, which is a link from the main HANA site of http://scn.sap.com/community/developer-center/hana. zip folder: "sap_hana_win32_studio_rev80"
Targeted O/S: Windows 7, 32-bit, local Java is SE 7, update 67.   Java environment has been confirmed via checks provided at http://www.java.com/en/download/manual.jsp
Actions taken:
Attempted to update the installation's eclipse.ini file by reducing the -Xmx value; see details below.
Read thru postings such as http://scn.sap.com/thread/3390626 and the threads it recommended.
Checked OSS (ie Note 1859686 - HANA Studio does not start)
Description of installation error:
Shortly after executing "hdbinst", it fails with the error "Could not create the Java Virtual Machine". I've verified that there is nearly 3G of memory free. What I did notice, as shown in the attached files, is that Eclipse is part of this installation and it's pre-loaded with the "eclipse.ini". I firmly believe the solution could be to reduce parameter "-Xmx1024m" to "-Xmx512m" but it's a catch-22 because even after updating eclipse.ini (in installation folder C:\Program Files\SAP\hdbstudio\tmp_p2director2014.08.13_13.36.44\director), the install program requires that the "hdbstudio" folder to be empty upon restarting it.
Since the installation is basically a package with a lot of .jar files, there is no eclipse.ini file available in the source install folder; otherwise, updating it there would be the easiest solution if that option were available. The file is only available in the targeted deployment folder above.
If you have encountered this same error and were able to resolve it, I would be grateful to know of your solution. Thanks very much.
FYI: the HANA Client installed with no issues.

FYI: the images below reflect the sequence of images produced during the installation.
after clicking OK above, the screen below gets updated (see the "is not empty" msg).
Below is the eclipse.ini file located in the deployed/target folder:
Message was edited by: Jim Cleek
FYI: Using information from the SAP HANA Database - Studio Installation and Update Guide, I tried to override the installation's use of its eclipse.ini file by passing my own modified version (with "-Xmx512m") of that file that was placed in a separate folder. The cmd used via DOS window was "hdbsetup.exe -a studio --configfile=C:\Users\Admin\Downloads\eclipse.ini" and even though it successfully launched the SAP HANA Lifecycle Management gui, it failed on the first step with the same JVM create error as above because it appears to have used its own eclipse.ini file, which has "-Xmx1024m".

Update: a message was opened with SAP but unfortunately they could not provide a resolution for this particular scenario. They admitted that the eclipse.ini file cannot be updated since it is bundled as part of the installation package. One point to make that I did not make before was that this was being attempted on an Oracle VirtualBox (4.3.10); the SAP HANA contact said he assumed that SAP has not tested this particular scenario, thus it could not be supported.
Resolution: the end result was to abort trying to install SAP HANA Client and Studio on the Oracle VirtualBox but to install it locally on my own desktop, which runs on Windows 7 Enterprise 64-bit with 8G of memory. The SAP HANA files below were downloaded, extracted and installed successfully in the order shown.
FYI: the Studio installation detected that a 64-bit version of Java was not installed so I installed that and then adjusted the User environmental variable JAVA_HOME to point to that new path, leaving the System variable still pointing to the pre-existing 32-bit Java path.

Preinstall check failed - Unable to install SAP HANA Client

Hi all,
Recently I had to format my system and after loading the Windows 8 I downloaded the SAP HANA Client, SAP HANA Studio and SAP HANA JDBC Drivers for re-distribution from https://hanadeveditionsapicl.hana.ondemand.com/hanadevedition/ into the default folder which is C:Programfiles:SAP HANA Client and Studio
I installed the client and then the studio and then clicked on the executable ngdbc.jar file and clicked on ok.
Then I went to SAP HANA 70 client win32 folder and clicked on the hdbsetup to load client. I am getting the following error:
Preinstall check failed
SDB::Install::System::getMountPointWin: Malformed file path normalization: "ngdbc.jar"
Can any one please explain what this error is and how do I fix this error. I searched in the forum but could not find anything related to this error.
Thank you.
Regards
Pavan.

I am posting the results of my issues here, to be sure this is documented.
Close all applications
Uninstall SAP/b1 and all related components
Delete folder X:\Program Files\sap
Delete folder X:\Program Files (x86)\sap
Open REGEDIT and clean out all parent keys where "HANA" appears
Install the SAP/b1 client first!
Run the HANA Client installation "...as Administrator"
When the installation runs, it should default to "Install new"
Make sure you set/select the folder path properly to show X:\Program Files\sap\hdbclient
Once the clean-up was finished and the install was restarted, it installed without any issues.
Thanks,

Package checkout failed : SAP HANA Studio

Hi Experts, I am facing issues while checking out packages from HANA Repository. Once i choose the check out option, the corresponding folder is not getting created in the local repository directory and the tick sign also not showing along with the folder. But no error messages are shown the HANA Studio. Please help. I am using SAP HANA SP07 Regards Sreehari

Hi Mr Bechmann,
I have solved this issue by creating manually the folder hierarchy locally.
If for example my new package (newpack) was under sap.pack1 (sap.pack1.newpack),
I've created a workspace whatsoever called (myworkspace) inside the root workspace folder locally
I have created a folder hierarchy like this: workspace > myworkspace > sap > pack1 > newpack
then I have created a new project and put it under newpack folder
I'm using SP7, how can I make this automatically? With regi was everything checkout and created automatically.
Thank you,

Uninstall SAP HANA server tool

Hi Experts,
I want steps on how to uninstall SAP hana server tools.
I didn't find any way to do that so I deleted the folder but with that when I try to install server components I get error failed ,roll back.
Urgent help on how to uninstall SAP HANA server tools to unable me install new package.Linux.
Regards
Justice

Hi Justice,
Try:
rpm -q -a | grep B1 | xargs rpm -e
And then try reinstallation.
If it works, next time when you uninstall B1 on Linux, please use the uninstall.bin located in the installation path, typically opt/sap/SAPBusinessOne. You can find the instructions in the Administrator's Guide (HANA version), which is in the product package \Documentation\SystemSetup\ and also in the Packages.Linux folder.

SAP HANA D3 Library errors - "queue" is not a function

Hello all,
i have a question regarding D3 Integration into SAP HANA and hope one can help me.
The last days i developed a D3 Choropleth (spatial data) with hover effects, tooltips and a legend. I have an existing SAPUI5 and HANA XS application running and now i wanted to integrate my D3 Choropleth.
1 ) First of all, i added the following tags into the head section of the index.html file of my SAPUI5 project as i need those libaries.
<script type="text/javascript" src="http://d3js.org/d3.v3.min.js"></script>
<script type="text/javascript" src="http://d3js.org/queue.v1.min.js"></script>
<script type="text/javascript" src="http://d3js.org/topojson.v1.min.js"></script>
2) Then, i added the program code of my D3 Choropleth into the view.js of my SAPUI5 project:
var html2 = new sap.ui.core.HTML("d3choropleth", {
                content: "<div class='D3Choropleth'>" + "</div>",
                preferDOM: false,
                afterRendering: function() {
                              .... here is my code ...
I have a SAPUI5 shell with different NavigationItems (tabs) and for this D3 Choropleth tab i am writing:
case "WI_choropleth":
oShell.setContent(html2);
break;
When i start my SAPUI5 project and klick on the tab where the D3 Choropleth should be rendered, i get the following errors:
d3.scale.threshold is not a function
d3.geo.albers center is not a function
queue is not a function
Moreover, i have to say that my D3 Choropleth works standalone outside HANA very well, that is why i assume it is a library integration issue.
In my browsers (firefox) developer console i can see that there is a D3 library loaded by default (as it is one of SAPUI5s components) with the path: sap/ui5/1/resources/sap/ui/thirdparty/D3.js.
BUT this is a really old version of D3 (2.9), the current release is D3 (3.4), so maybe the problem is that the D3 libary that is loaded by default overwrites my integration of D3 (script tag above)?
Does anyone have the same issues and knows how to solve that? Furthermore it seems that the d3 queue library is also not integrated as the error "queue is not a function" occurs and i also ask me how to solve that error.
We have SAP HANA Developer Edition Revision 80 (by AWS), HANA Studio and Client are on revision 73 (64bit).
It would be great if anyone could help me with my issue.
Further question: Is the current release of D3 going to be integrated into the next HANA revision?
Thanks a lot & regards,
Andreas

Hi Andreas,
You are right. The way you integrate the libraries in your code is not the way that will work for HANA XS projects. This is why it doesn't accept the queue function (library is not loaded) and also why the 3.x only D3JS funcitons are not accepted (only the internal D3JS library is loading and these functions were not a part of 2.9 yet).
To integrate third party libraries, you need to add XSJSLIB files to your project. These need to pass the server-side JSLint checks before accepted by the XS engine. (Client-side checks that fail might not count though).
Please see this post from David Brookler for more information.

SAP HANA One and Predictive Analysis Desktop - Time Series Algorithms

I have been working on a Proof-of-Concept project linking the SAP Predictive Analysis Desktop application to the SAP HANA One environment.
I have modeled that data using SAP HANA Studio -- created Analytic views, Hierarchies, etc. -- following the HANA Academy videos. This has worked very well in order to perform the historical analysis and reporting through the Desktop Application.
However, I cannot get the Predictive Analysis algorithms -- specifically the Time Series algorithms -- to work appropriately using the Desktop tool. It always errors out and points to the IndexTrace for more information, but it is difficult to pinpoint the exact cause of the issue. The HANA Academy only has videos on Time Series Algorithms using SQL statements which will not work for my user community since they will have to constantly tweak the data and algorithm configuration.
In my experience so far with Predictive Analysis desktop and the Predictive Algorithms, there is a drastic difference between working with Local .CSV / Excel files and connecting to a HANA instance. The configuration options for using the Time Series Algorithms are different depending upon the data source, which seems to be causing the issue. For instance, when working with a local file, the Triple Exponential Smoothing configuration allows for the specification of which Date field to use for the calculation. Once the data source is switched to HANA, it no longer allows for the Date field to be specified. Using the exact same data set, the Algorithm using the local file works but the HANA one fails.
From my research thus far, everyone seems to be using PA for local files or running the Predictive Algorithms directly in HANA using SQL. I can not find much of anything useful related to combing PA Desktop to HANA.
Does anyone have any experience utilizing the Time Series Algorithms in PA Desktop with a HANA instance? Is there any documentation of how to structure the data in HANA so that it can be properly utilized in PA desktop?
HANA Info:
HANA One Version: Rev 52.1
HANA Version: 1.00.66.382664
Predictive Analysis Desktop Info:
Version: 1.0.11
Build: 708
Thanks in advance --
Brian

Hi,
If you use CSV or XLS data source you will be using Native Algorithm or R
Algorithm in SAP Predictive Analysis.
When you connect HANA, SAP Predictive Analysis uses PAL Algorithm which runs
on HANA server.
Coming to your question regarding difference,
In SAP PA Native Algorithm, we could provide the Data variable, Algorithm
picks the seasonal information from the Data column. Both R and SAP HANA PAL
does not support Date Column. We need configure seasonal information in
Algorithm properties.
R Properties
1) Period : you need to mention the periodicity of the Data
Monthly : (12)
Quarter : (4)
Custom : you can use it for week or Daily or hourly.
2) Start Year: need to mention Start year.
Start year is not used by algorithm for calculating Time series, but it helps
PA to generate Visualization ( Time series chart) by simulating year and
periodicity information.
3) Starting Period:
if your data is Quarterly and you have data recordings from Q2, mention 2 in
start period.
Example.
If the data periodicity is Monthy and my data starts from Feb 1979, we need to provide following information,
Period: 12
Start year: 1979
start Period: 2
PAL Properties. : Same as properties defined in R.
Thanks

SAP HANA: IMPORT/EXPORT Views

We can Import/export tables using hdbsql CLI.
But Is there any way by which we can export/import Views(attribute,analytic,calculation) using hdbsql CLI.
I raised above question some days back
SAP HANA: IMPORT/EXPORT Views | SCN
Also while checking on internet I found another link for the same issue:
http://scn.sap.com/thread/2141404
And from experts answers, I came to conclusion that Import/Export Views(Attribute/Analytic/Calculation views)in SAP HANA is not possible through hdbsql CLI/ SQL commands.Now Is there a way where I can confirm this from SAP HANA program management guys?

Lars,
Thanks for the explanation.
What I am trying to achieve is to create an automate script which should export all tables and views for a schema and again import tables and views in a different schema.
table part is done, But stuck in view part.
I tried the below command and was able to export the calculation view which I created in Content and exists as
_SYS_BIC-->Package(same name as schema where all the tables are stored) --> View Name.
Command used was:
EXPORT "<Schema_Name>"."<Package_Name>/<View_Name>" INTO '<path>'
Now I have 2 ques :
1) I am not sure how to import this exported view. I tried below command but it failed:
IMPORT "<Schema_Name>"."<Package_Name>/<View_Name>" FROM '<path>'
2) Not sure how to export and import all the views.
I did IMPORT SCAN of the path as well and found below entries for the exported view in the mentioned path:
SCHEMA_NAME, OBJECT_NAME, OBJECT_TYPE, EXISTS
"_SYS_BIC", "<Packagename>/CalculationViewName>", "VIEW", 1
"_SYS_BIC", "<Packagename>/AnalyticViewName>", "VIEW", 1
"_SYS_BIC", "<Packagename>/CalculationViewName>/olap", "VIEW", 1
"_SYS_BIC", "vwTile1ALLData", "VIEW", 1
Any Inputs would definitely help. Thanks.

Which ports are needed for SAP HANA Studio - HANA DB communication?

I want to connect SAP HANA Studio to a HANA instance. The HANA instance number is 40.
The SAP note 1592925 states that the ports 5$$13/5$$14 and 3$$15 should be open to allow communication between the HANA Studio and the HANA database. I even see the instance in the HANA Studio, but I cannot administrate it and the HANA studio gives this general "I don't want you to know what the error actually is" message:

Do I need to open any other ports to make HANA Studio work with HANA DB?
Regards,
Mark

Hi Mark,
The HANA Studio connects to HANA DB Instance with JDBC on port 3<Instance number>15.
For your HDB with Instance Number 40, the port would be 34015.
HANA Studio will automatically assign the JDBC port number when you assign the instance number when you add new system.
Looking at the error message that you posted:
!ENTRY com.sap.ndb.studio.navigator 4 1 2012-01-16 14:01:40.627
!MESSAGE [HDB hostname 40 (SYSTEM)] Error on refreshing system
It looks like the hostname entry was not entered correctly (you might have entered "hostname" value when adding the system in HANA Studio).
Here is an example of correct log entry on DCA database instance on hanasvr-01 server with Instance number 00:
!ENTRY com.sap.ndb.studio.navigator 4 1 2012-01-10 13:55:23.598
!MESSAGE [DCA hanasvr-01 00 (SYSTEM)]
You may want to delete and re-add your HDB instance in your HANA Studio.

Ferry

CompositeProvider Data Preview "Error in the BWA/SAP HANA Server"

Hello Experts,
We have created CompositeProvider in HANA Studio. When we are trying to preview the data in CompositeProvider, we get the below error message.

We are now in BW on HANA 7.4 SP8 and facing issues with the Reports based on this CompositeProvider. The CompositeProvider is already in active status and the system check was successful.
We have identified SAP Note : 2019244 for this issue but this is not relevant for our system configuration.
Please let me know if anyone has encountered this issue.
Thanks in advance !

Hello Pradeep Kundeti,
Please raise an Support ticket with SAP asap, so that you can save some time.
If its a new error, SAP might take some time to rectify it. So it's better to keep them informed.
Let the experts come up with their suggestions....
PS: Yours is a comparatively newer system and there are possibilities that new errors might come in...

I must add, that i test it in the firm's intranet. So we have diverse firewalls. What firewall settings has our IT department change, for enabling the database connection?
Hope you can help me.

SAP HANA Web-based Development Workbench Privileges

I can get into and use the SAP HANA web-based development workbench as the SYSTEM user, but I cannot as other users.
http://localhost:8005/sap/hana/xs/ide/editor/
Currently as any other user, I get the following error: "Request execution failed due to missing privileges"
What are the appropriate privileges that need to be set in SAP HANA Studio to access the web based IDE?
Currently, just messing around with the privileges in SAP HANA Studio, if I set the following application privileges, I can at least log in as another user besides SYSTEM.
However, I cannot get any of the files to display in the editor portion of the SAP HANA web-based development workbench. A possibly related error in the log console: "13:10:12 >> Error in WebSocket Connection to backend."
I found this thread discussing the same issue I believe, but the solution I would imagine is not correct: HANA XS Administration | SAP HANA
Thanks,
Kevin

Hi Fernando,
Thanks for the suggestion. That seemed to work, though it is strange that it is not one of the *.xs.* application privileges. So, just to be clear, here are the application privileges I have now in order to use the web based IDE:
