Regarding BW precalculation server monitoring

Hi Experts, we have BW precalculation server configured in pur NW2004s BW system. My requirement is if i can monitor RSPRECADMIN using Solution manager. Like if precalc server goes down it should generate an alert.
Any inputs on the above would be much appreciated.
Thanks Amber S

As indicated [earlier here in SDN|How to monitor Bi Precalculation?;,there is no MTE for monitoring Precalc. The work-around is to monitor the BI RFC PREC_<SID>. This provides a better end-to-end check than simply checking the Windows service on the Precalc server. Rather than monitor the RFC on the remote system, I simply created a duplicate of the RFC on the Solution Manager system, and monitored that.
See [Monitoring Availability of Services|http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/70531389-0c01-0010-2a95-c019524764ae] (PDF) for a description of RFC monitoring.
Also, here are some notes on data collection method CCMS_RFCDest_Availability_Col:
SAP Note:0570083 CCMS: RFC Destination Monitoring does not work
SAP Note:0771455 CCMS: Incorrect MTE Class in RFC Destination Monitoring

Regarding BW precalculation server

Hi gurus,
We have BI 7.0, SAPGui 7.10, SAP Netweaver 2004s, Also we use Microsoft office 2003 (No SP installed) I want to precalculate workbooks and broadcast the same. Could I know what version of .NET as well as what
precalculation server version should I install on my PC so that I can broadcast workbook.
Regards
Sree.

Dear Mr. Varadarajan,
The note 745206 provides you with a link to download the latest BEx Precalculation server, and the path that you gave has two precalculation servers listed in it. I have already known about them, however, I want to know which one is the latest one. Is it the one provided in the notes, i.e. BExPrecService.exe or is it xPreCalServer06_1-10004472.msi or is it xPreCalServer08_1-10004472.msi. At the same time, the .NET framework that i am gonna use would be a 2.0 SP2, so will both of these be compatible.

Is Precalculation server a prerequisite for Information broadcasting

Hello Everybody,
I wanted to know is installation and configuration of pecalculation server a prerequisite for enabling Information broadcasting feature in BW 3.5 i.e; inorder to send emails to users .I mean inorder to send mails to users is it necessary to install pecalculation server first.
Regards,
Saumya

The Precalculation server is only needed if you want to distribute workbooks. In order to distribute workbooks, the BW needs access to a computer with Excel on it. The precacluation server service software can be installed on a standard desktop PC. It can be installed on mutliple desktops, or you can consider a centralized server, but for initial testing, a desktop will do. There are a number of OSS Notes to apply, several from SP 17 that deal with problems occuring as a result trying to distribute multiple wkbks simultaneoulsy.
You do NOT need it to distribute either query links or html formatted output.
You also need an IGS server if you want to be able to send your output in a zip file format.
Don't have the link handy, but try searching SDN on Precacluation Server - there is a good paper (think it was a How To...) that was just written in April on troubleshooting Precalculation Server issues.

Precalculation server: problem with precalculation of a single workbook

Hi all,
We noticed a strange error while precalculating a workbook. Broadcasting to portal (or sending via E-Mail) of this workbook always fails with the following error text:

Other workbooks work fine. I've already created a new precalculation server but it didn't help. Has anyone an idea what could be the cause or why this just happens with this workbook?
Any advice could be helpful.
Regards,
Chrigu

Hello All,
When you have an issue with a single workbook, try to open and re-save this workbook.
This is probably happens with Chrigu. Someone opened the workbook and save again.
Also, another tip.
Open BEx Analyzer -> Click on "Global Settings".
Check the option "Repair workbook while execution" -> click "Ok"
Execute and save the workbook.
This should solve issues with a single workbook.

Issue when Bursting reports via new Precalculation Server

Hello,
We are trying to migrate away from our unsupported 720 installation of the SAP Precalculation software to a new Precalculation Server running the latest versions. We’ve overcome a number of issues and we can successfully Broadcast using the new server but we are encountering problems
with bursting.
The Bursts have been running successfully on the old 720 server, so we know that the BW side must be fine which suggests the problem is with the Precalculation server. We have been through the Precalculation checklist and the servers appears to have been built successfully. The Precalculation and Business Explorer software has been patched to the latest version and it’s running Excel 2013.
The main error message we are seeing is “The RPC server is unavailable” HRESULT: 0x800706BA.
A Screen shot showing the error in RSRD_LOG is shown in the attached document.
Below is an extract from the Log of the Precalc server showing this error, just before the RPC Server is unavailable message it states
Error occured on closing opened workbooks.

Precalculation Server for Information Broadcasting

Hi Folks,
Do we need Precalculation server to use Information Broadcasting in BW7.0?
I am especially interested in using the Filling OLAP Cache functionality in Information Broadcasting to fill OLAP cache for one workbook.
Need your help on this.
Regards,
Sn

Hi Raghavendra \ NS,
We have only one application server. The issue might be because of the broadcast settings which I am giving to fill the OLAP Cache.
In my current query there are two variables one is on business unit and the other one is on calendar month. Both the variables are optional.
Business Unit variable accepts multiple single values as input and the calendar month is selection-option variable.
Now My problem is if I fill cache with a variant, without providing any value for Business Unit variable (i.e for all the business Units ) and Calendar month values as 01.2010 to 11.2010, then when I execute the query for Business Unit x and Calendar month 10.2010- this is not picking data from cache instead reading from the database. Ideally this selection is the subset of the cache which I have filled.
The query is picking data from the cache only if I give the same variable values i.e no values for Business Unit and 01.2010 to 11.2010 for calendarmonth.
My requirement is to fill the cache for all the Business Units and all the calendar months of current year. This cache should be accessed by the query even if user selects one or multiple or all the Business Units and a single or range or all the calendar months of current year.
I might be doing something wrong in settings of BEx broadcaster. Please throw some light on the settings which I have to make in this case.
Regards,
SN

Server Monitor error - "CANNOT LOAD BUNDLE ERR"

I got 2 Xserve(s) intel based - 1 installed 10.6.8 and the other 10.5.8 - both server(s) are upto date on software updates.
Server Monitor works fine on both of these server(s) when run locally (from the server). When I run the Server Monitor from my local machine (still in the same network), the server with 10.5.8 works fine, but the server with 10.6.8 shows the error "CANNOT LOAD BUNDLE ERR". I am not sure where I am making a mistake.
Any help highly appreciated..:)

Workbook - Precalculation server

Hi,
W consider publishing workbooks in our SAP BI Portal. (BW/NW Portal 7.0).
Is it mandatory to install the precalculation server or can we publish workbooks with out installing this server component?
- What's tha advantage/disadvantages?

Hello,
Yes, it is mandatory a precalc. Server if you want to publish Workbooks. There is no other way.
However, you can publish queries without a Precalculation Server.
So, you can publish the queries used on the workbooks without a precalc. server. This is only a workaround.
Thank you for your attention.
Best regards,
Edward John

Sizing of precalculation server and workbook description while broadcasting

Hello Gurus,
First
i have a question concerning broadcasting. First we installed one precalculation server on a desktop but after creation a lot of settings for broadcasting a workbook the sending vial email or portal did not show the workbook (numbers, textitems) correctly. I just saw NV for the numbers.
Then i deleted the broadcast settings from transaction RSRD_ADIM. After created one setting again after the deletion of all the settings i broadcasted one workbook via email successful. --> my suggestion was that it depends on the settings created for a precalculation server. Sizing is a problem, broadcasting the workbooks correctly. is there a relationship one precalculation server how many workbook broadcast settings?
Second when i broadcast a workbook via Email the name of the attached file is:
WORKBOOK_XXXXXXXXXXXXXXXtechnical nameXXXXXXXX.XLS
This name is meaningless. Is there a possibility to change the name of the of the broadcasting file?
Thanks and kind regards,
Murat

Hi Murat,
First: yes, there is a limitation on how many workbooks a precalculation server can process at once.
The older load balancing server version (see note 1275837) had the following environment variable to control how many instances it should start at a given time:
(Control Panel -> System -> Advanced -> Environment Variables) BEX_PRECALC_INSTANCES = 1. In this case, only one instance would be started at a time (that is, a workbook would be processed after another).
Second: No. It is not possible. I had a request here at SAP some time ago and the development said that it is just working as designed and no plans to develop such functionality were ongoing at that time.
Kind Regards,
Marcio

SAP BW info broadcasting precalculation server

hi all,
I would like to know whether precalculation server saves the calculated workbook before posting (via Email or Portal) anywhere? If so, then where?
Thnx a lot.

Hi,
I just want to add few more lines to above explanation,
When I say that processing happens on precal server means it actually does the formatting of the report on precal. The actual data or query processing happens on App server and then data goes to Precal there it gets formattted as per the output type of broadcast. And again it comes back to SAP from there MAIL will be triggered.
You can check the mail status in SOST transaction.

Durgesh.

Configure precalculation server as unicode ?

Hello,
I have national symbol problem described here:
[Regional symbol problems using precalculation server ?;
We just compared correct report made interactively by live user and incorrect one made by precalculation service - looks like correct xls file chars are encoded by double byte, while incorrect one is encoded by single byte.
Other fact is that precalc server RFC connection test if "MDMP & Unicode" is set to Unicode, never works:
SM59->TCP/IP connections->PREC_OURPRECSERVER->MDMP & Unicode->Unicode
returns:
connection closed (no data)
While RFC conn test is OK if "MDMP & Unicode" is non unicode.
We concluded that our precalculation server runs as non unicode.
Very similar problem here:
[http://sap.ittoolbox.com/groups/technical-functional/sap-bw/precalculation-server-number-sign-at-the-workbooks-1844478]
Any ideas how to configure precalc as unicode ?
Any other ideas ?

Server Monitor Notifications - Drive Status Changed - Time Machine

I'm using an Xserve as a file server for a small workgroup . It has a Raid 1 set which is being backed up via Time Machine to an attached disk array.
Whenever Time Machine runs (every hour), I get two notifications from Server Monitor that the drive status has changed:
*Reason(s) for notification:*
*Drive status changed*
The timestamps on the notifications coincide with these messages in system.log
Feb 2 11:28:05 ciesaxserve2 Server Monitor[854]: * _NSSocket.m:243 read() failed; socket=0x197060 error=(NSPOSIXErrorDomain,61)

Feb 2 11:28:05 ciesaxserve2 Server Monitor[854]: * _NSSocket.m:243 write() failed; socket=0x2090e90 error=(NSPOSIXErrorDomain,61)
and:
Feb 2 11:28:55 ciesaxserve2 servermgrd[78]: servermgr_backup: TimeMachinePostBackupHook called.
Feb 2 11:28:55 ciesaxserve2 servermgrd[78]: servermgr_backup: TimeMachinePostBackupHook done.
The notifications simply report that all is normal, and the number of available drives goes from 6, to 7, back to 6. Something to do with making the backup volume available, I presume.
I would like to disable these specific messages. I realize I can disable all messages from server monitor regarding disk statuses, but then I would be turning off messages about failures and actual problems.
Is there a config I can edit which will only alert me to actual problems? I'd like to stop getting 48 emails each day; reduce the noise and increase the signal.

I know this post is old but this has recently cropped up for me. I have been backing up with Time Machine for months without a single alert. It started happening after I replaced the failed battery on my RAID card. A coincidence...however the prolonged down time surely caused an SMC (and perhaps PRAM) reset which I assume triggered the change in behavior.
I've pinned it down to Time Machine backing up service settings, in particular the Open Directory archive. Time Machine backs up all the service data independently from the rest of the data on your server startup volume.

You can see this data in Terminal.

The ServerBackup_OpenDirectoryMaster.sparseimage contains an archive of your Open Directory database like the one you create from Server Admin. The only difference is that it appears to be unencrypted. This is a bit worrying since Snow Leopard, as far as I know, does not have an option to encrypt your Time Machine backup. This image seems to invisibly mount whenever a Time Machine backup is triggered. This can be verified by checking /private/var/log/system.log and filtering for backup

Jun 4 16:10:29 yourservername com.apple.backupd[25117]: Backup completed successfully.
You can see at 16:00:56 Server Manager got a call from Time Machine to start the services backup and finished at 16:09:26. Open Directory would have been backed up during that process. Take a look at /private/var/log/hwmond.log
serveradmin$ tail /private/var/log/hwmond.log
Tue Jun 4 16:08:36 BST 2013 - Number of drives change from 4 to 5.
Tue Jun 4 16:08:48 BST 2013 - Number of drives change from 5 to 4.
You'll see that both drive change warnings from Server Monitor occured just before the services backup completed. You can also use the sudo diskarbitrationd -d command along with tail /private/var/log/diskarbitrationd.log in another terminal window, trigger a Time Machine backup manually and watch this disk image mount during the backup process. Compare the mount times with the above logs to see if they all match up.
Although I have discovered the cause (which thankfully seems harmless) I have not discovered a way to stop it from generating pointless alerts. I'll post here if I figure it out. I am in the process of upgrading all of my servers to Mountain Lion so it may be a moot point. I am hopeful this information may help someone out there even though it is thoroughly out of date.
