Excerpt from above Simba Technologies CEO blog*
One interesting thing we found from some of the Beta customers is that they thought this was an Excel only solution. Yes, we are focusing all the efforts for v1 on Excel, but this is planned to be a full blown MDX provider for Oracle OLAP*. Therefore, you will get the entire MDX query language and this interface will be similar to what you have with Microsoft Analysis Services or SAP Business Warehouse. Although v1 will be ODBO only, we are planning to support XMLA in future versions. The priorities for what we support and when will be customer driven. One question I have is after Excel, which MDX application do you think we should test with and support next:
1. SAP Business Objects Crystal Reports
2. SAP Business Objects Voyager
3. MicroStrategy 9
4. Microsoft Reporting Services
5. Microsoft SharePoint BI
6. IBM Cognos Business Intelligence 8
7. Panorama NovaView
.

Thanks very much for your response. Pls find the details as requested. You can reach me in [email protected]
Environment Details
- BO XI 3.1 SP4 Enterprise Premium (incl Voyager) on Win2008 R2 [Tomcat Flavour]
- Oracle 11.2.0.1 Enterprise Edition with OLAP on AIX 6.1
- Simbha MDXProviderForOracleOLAP v2.1.0.23 on Win2008 R2
Cubes are built using AWM 11.2.0.2A.
To be more specific, the issue occurs when we attempt put a filter on the dimension (or select members of the dimension) both in the existing workspaces or when we try to create a new workspace in Voyager. Attaching the screenshot of the error message.
Kindly let us know incase you would require further information. Also, if you would like to have a webex session where I can show the issue, I am happy to do the same.

New to XML and Oracle

Just trying to clarify some issues as I try and learn about XML, and specifically how it integrates into the DB.
1 - Is there a way with Oracle tools for me to get an XSD of an existing 9i relational schema? We are not currently using the XML DB, but our middleware developers would like to have an up to date XSD to use for their internal mapping.
2 - Is there any way that I can keep that XSD up-to-date automatically, so I get a new one whenever the schema gets updated?
3 - If I wanted to investigate storing XML docs within the DB in native XML format, I need to have an XML DB, correct? Is this DB construct maintained seperatelly from my "normal" relational schema? or are they kept in sync by Oracle?
I know these may all be real basic questions, but as I said, I'm new to XML and Oracle. I am reading as much as I can, but there are a lot of docs out there.
Thanks,
Mike

Hi
1. On my opinion such a tool doesn't exists. Some parts can be implemented elsewhere, but not as described by you... e.g. with XSU if you specify the parameter "withschema" the XSD of the executed statement is generated. Another example is to use DBMS_METADATA to dump the data dictionary in XML (but not XSD, of course you could write your own XSLT to do this transformation...).
2. -
3. If you use XSD-based tables the XSD and the relational model are stored separately in the data dictionary. Therefore if you change the XSD you have to drop/create the XSD-based table... no schema evolution yet.

HT4796 Hi, I've just bought a new Macbook Pro and started migrating from PC but the remaining time is about 70 hours long, I just wanted to know if that timing is normal and if not, does leaving running my MacBook that time can affect it?

70 hours... no, it's not normal but it can't hurt your Mac to be running for that amount of time.

Just got a new macbook pro and transferred files from my old macbook. Everything is fine except my iphoto will not show photos.

I just got a new macbook pro and transferred everything from my old macbook. My photos show up as thumbnails in iphoto, but if I click on them, a "?" pops up for all of them!

Copy the Library over manually.
To move an iPhoto Library to a new machine:
Link the two Macs together: there are several ways to do this: Wireless Network,Firewire Target Disk Mode, Ethernet, or even just copy the Library to an external HD and then on to the new machine...
But however you do choose to link the two machines...
Simply copy the iPhoto Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.
Then launch iPhoto. That's it.
This moves photos, events, albums, books, keywords, slideshows and everything else.

OBIEE and Oracle OLAP Value Based Hierarchies

Hi there...
I have a value based dimension built on Oracle OLAP and want to map it on OBIEE Administration tool.
I've been using the above link as reference:
http://www.oracle.com/technology/obe/olap_biee/CreateBIEEMetadata.htm
There's no option to import from Oracle Multi-dimensional Database. Either to import/configure the view created by OLAP as an Unballanced or Ragged Dimension.
I also checked this example, but it uses ESSBASE as the multi-dimensional source....
http://www.rittmanmead.com/2008/08/27/ragged-hierarchy-handling-in-obiee/
How to map this Ragged Dimension created in OLAP workspace in OBIEE? Any suggestions or directions will be highly appreciated...
Thanks in advance
Marcos

Mark and others,
You can create OLAP_TABLE views with level columns on top of value-based hierarchies. BI Beans used to do that too behind the scenes in Discoverer Plus OLAP. If you trace the Discoverer session, where you are querying data from Value-based hierarchies, you will see that it also generates OLAP_TABLE views with level columns in it.
So the question is how to do it. Internally, even for Value-based hierarchies Oracle OLAP keeps track of the "depth" of each value by using a structure called GID_DIMENSION (i.e., Grouping Dimension). Here is an example of a view on top of a value-based hierarchy (CFC_ACCT_GAPP) for RPT_ACCOUNT dimension. You have to know how "deep" your value-based hierarchy is.
Similar kind of a thing is done by OLAP View Generator application, which I never use - since I always prefer to define my own OLAP_TABLE views.
This kind of a view can then be used in the RPD of OBIEE.

HOLAP - using OBIEE and Oracle OLAP

Hi
How to implement HOLAP in OBIEE (with Oracle OLAP cubes) as below –
1. For an aggregate table, there are 3 dimensions each one having 4 levels within its hierarchy.
2. We create an aggregate table at the lowest level of each dimension.
3. We create a cube for rest of the levels and its combination for the same measure.
Can we implement this and how?
Thanks

Thanks Nazar for your reply.
On Cube based MV usage - The idea is to have lowest level summaries in relational. Higheer level in cube based on MV. So in case there are queries that can get rewritten , they will retrieve data from the cube itself.
On hierarchies -
If we take the example of oracle provided GLOBAL application and check the product dimension -
========================================================================

Now , if this was TYPE 2 dimension and if you had possibility of late arriving sales data where you need to pick up "point in time" attributes of the product. How can I model dimension hierarchy in that case in OLAP?
In the Oracle example, they have kept it simple TYPE 1 so ITEM_ID can be kept as the key. However, if I had the PRODUCT_DIM as a TYPE 2 dimension table and i was using sequence generated surrogate key as the PK of the dimension table, how do i model it in OLAP?
Thanks

Does an iTunes backup not include the calendar?
The backup was from mid-september and I think iTunes was the latest version at the time..

This will happen if you have photos in your camera roll and an out-of-date scanner or webcam driver. See this: http://support.apple.com/kb/TS1502

How to set up a new iPod Touch and transfer data from old IPod Touch

ok, it's Friday night, I finished the cheese and about 1/2 a bottle of wine (myself... not ideal for a smurf my size) and I still can't find the answer to my question after searching [to the best of my most current ability] all over the forums (I even searched long before I started drinking wine). I appologize right now for my ignorance and inability to find the answer on my own.... but could someone PLEASE, just tell me the best way to kill my daughter's Ipod Touch 2nd Gen (advertised as Gen 3, ha, ha, on me), and set up her new-(to-us) Ipod Touch Gen 4? I've already backed up her old device to my computer? (it's a PC - sorry, it's free from my husband's office)
Do I set up her new-ish Gen 4 as a "new device" or "restore from back up?" She's young enough (grade school - & why she gets old/cheaper HW) that we both still uses my iTunes acct for her device and mine so that I own & can monitor/manage the music that we both listen to... but this time I'll set up her own iCloud acct. Although the new device (let's call it device B) has been wiped clean from the last user, how do I set it up? New device or restore from bk up? Now that she saved up the $ I paid for it, to pay me, she's driving me crazy about getting it going for her. Her orig/current device, iPod Gen 2ish (we can refer to that as device A) has been backed up to my computer and I'd like to port all of her data (calendar, contacts, pictures/movies, etc) to her new device. Please help this old mom... my girl is driving me crazy... and I feel bad not delivering her goods. Many thanks.

I need to create a new iPhoto library and import 'ORIGINALS' from a time machine backup on an external hard drive.

I made the mistake of installing OS 10.9 on my older MacBook Air and the machine has become horribly slow and unpredictable. I visited the Apple store and questioned a 'Genius' about getting rid of 10.9 and reinstalling the previous OS 10.6 for which I have the disks. He advised that I should reformat the Air, reinstall 10.6 and then restore from the Time Machine backup that I have.
He explained that of course, after I reinsatll 10.6, I couldn't import the iPhoto Library from the backup drive complete because it had been recreated using the OS 10.9 and wouldn't work with 10.6. I would have to create a new 10.6 iPhoto Library and move the actual ORIGINALS, from the backup into it. He actually had the path to the iPhoto library shown on my Air to the point of >Pictures >iPhoto Library > ORIGINALS.
I didn't question how he got the path to the point of > ORIGINALS and figured that it wouldn't take too much to do what he suggested. Now I can't find how to get to point of seeing the ORIGINALS in the path. When I go through the path >Pictures >iPhoto Library, the next column shows me the iPhoto Library icon and the info re size, creation date etc.
Can anyone advise how to get to the 'ORIGINALS' in order to import them and does anyone have any further suggestions that might help in completing this procedure ?
Thanks, in advance, for any assistance available.
p.s. is there any way of looking at a Time Machine backup and finding what O.S. was present when the backup was produced ?

Rather than do that, which means starting over from scratch, losing all your edits, organisation and so on, why not simply use iPhoto Library Manager to revert the Library to the older version? Easier, less destructive.
The instructions on that are here
If you really want to start over: you can access the Originals folder simply by going to your Pictures Folder and finding the iPhoto Library there. Right (or Control-) Click on the icon and select 'Show Package Contents'. A finder window will open with the Library exposed.

I have a new MAC Pro and transferred files from a PC. Now I have about 100GB of real information but 300GB of other which I can't ID from summing up each folder and sum of applications, music, pictures etc. What could be occuping the 300GB OF OTHER??

I have a new MacBook Pro and used the tool to transfer information from my HP Computer to the MAC during set up. THe size of the disk space used on the HP was about 200GB. Now I have 400GB used on the MAC. I have added up all the folders and applications etc. and they total only about 110GB. On the summary the "other " category shows over 300 GB. What could it be. I would like to recover the space.

How to join data from SAP BW and Oracle database from Webi?

Hi,
Need to create a Web Intelligence Report connecting to multiple data sources.
Ø SAP-BW contains the data (All units).
Ø Oracle db contains the access security data (respective units
for the user).
Since Universe can only connect to a single data-source we have to create two universes connecting to SAP-BW and Oracle db respectively and then create a webi report to point the two universes to retrieve the equi-join data on the report.
May I know which layer I can join the data? What kind of data I can join?
Can I merge dimensions from both the data sources? What about measures?
How I can create SQL query in Webi in order to simulate the join to the two data source?
Appreciate any info related.
thanks and regards
nora

Hi Nora,
You can use Data Federator technology to federate multi-sources such as SAP BW and Oracle.
Las you just have to create a universe on the Data Federator data source and the universe isee the data source as a single source whereas it is not.
Then any clainet that consume uninverses can take advantage of this solution.

Physical size of dimensions and composites (Express and Oracle OLAP)

Hi, have a rather odd question re: the physical size (in bytes) of composites...are they affected by the dimension sizes?
I.e. if I define a dimension "Org" as:
define org dimension text width 10
will that result in smaller composites than if I define it as
define org dimension text width 30
? i.e. given that everything else if equal (same number of values, same # of tuples, etc.) does the physical definition of how wide a dimension is affect the size of the composites that use that dimension?
p.s. need to know this for Express, but if Oracle OLAP doesn't behave the same I'd like to know that also.
Thanks!
Scott

A 5 dimensional composite has keys built of 5 4-byte dimension positions. There is a copy of the 20 byte value stored indexed by physical position that we use internally to determine the value of the base dimensions. Also there is a copy stored in a hash table used to take the base dimension values and convert those back to a physical position (that's 20 bytes for the key and 4 bytes for the physical position).
Finally, we have internal structures ("inversions") that we use to essentially do "limit composite to base dimensions" for looping (for each base dimension value, a list of physical positions that have that base value in it), at 4 bytes per dimension or another 20 bytes.
That's 64 bytes. Yeah, it's not cheap, but compared to a dense variable, you save a ton of space. I seem to remember a calculation someone did a long time ago that said that composites were net smaller for anything less than 20% dense.
I'm not surprised that under certain conditions you can find a better data layout. Certainly the overhead of storing dense data is tiny compared to a composite. If you are clever (or lucky) in your segmenting, you can take advantage of the "holes" in the data to improve the storage. The "holes" (large groups of NA values) can go for many pages, if the faster varying dimension size is large, and won't be stored.
Oracle OLAP contains various improvements over the Express code. I believe we now use compressed bitmaps to store the inversions, rather than lists of values, for a substantial savings. There may be other changes as well (I'm not current on the details of the dimension storage).
Hope this helps.
Jim

New Apple ID and Movies Disappeared from iCloud

I changed my apple id to my new email address and now when I go into "purchased" in iTunes, all my previously purchased movies are gone. It's not even a category at the top where it says "Apps" "Music" "Books" "TV Shows", there's no "Movies" Does anyone know why?
I don't know if that makes sense or not. But basically what I'm saying is I no longer have the option to download my previously purchased movies from iCloud now that I have changed my apple ID. BUT it does allow me to re-download all my previously purchased TV Shows, Apps, Books, and Music. What do I do now?

i have the exact problem.. where can we ask for help?
