"trickle-feed" ASO Essbase

Hi all,
What is "trickle-feed" ASO Essbase...
Thanks

From the Essbase 9.3.1 readme:
The aggregate storage database model has been enhanced with the following features:
- An aggregate storage database can contain multiple slices of data.
- Incremental data loads complete in a length of time that is proportional to the size of the
incremental data.
- You can merge all incremental data slices into the main database slice or merge all
incremental data slices into a single data slice while leaving the main database slice
unchanged.
- Multiple data load buffers can exist on a single aggregate storage database. To save time, you
can load data into multiple data load buffers at the same time.
- You can atomically replace the contents of a database or the contents of all incremental data
slices.
- You can control the share of resources that a load buffer is allowed to use and set properties
that determine how missing and zero values, and duplicate values, in the data sources are
processed.

Trickle Feed

Hi All Gurus,
Can anyone please explain me how Trickle feeds work in ASO ?
As per my knowledge, it means the data is loaded into slices (buffers) and at the same time the old data is available to users. then we can merge all the slices and load the data to the cube. But my question is , can the users access the data even when the data will be loaded to cube from slices ? I tried looking for this answer on DBAG but was unable to find it.
Thanks

There have been a few posts on this subject in the past, these should give you more information

Re: is the essbase suit for near real time data analysis?
The user does not see the slice and will retrieve as normal.

ASO Trickle feed

Good morning
I see in the ORACLE literature concerning ASO cubes that it refers to sending slices of data to the cube as "trickle feed". Is this because the send function for the ASO cubes is not nearly as robust as Block storage? If not, what is trickle feed and how is it different from sending data?

Trickle feed is the (I think) old marketing name for ASO slices. Check out the DBAG, Tech Ref for more about it. Also, Angie Wilcox presented on slices at ODTUG's Kscope12 -- you can download the presentation for free from odtug.com's Technical Resources.
I believe at one time ASO databases could not have incremental data -- additional data forced clears and full loads. Slices are just a way to load additional data to an already populated ASO cube -- it's an incremental data load.
There's nothing less robust about ASO sends (which, btw, is a itsy-bitsy slice), but they are different than BSO lock-and-sends. Again, the docs will explain.

ASO trickle feed option

Hi All
Can someone please explain me what is Essbase's trickle feed option in details and how can one use it?
I'm looking for the ways to build near real-time cubes and heard that potentially 'trickle feed' option introduced in Essbase 9.3.1 could help, but unfortunately there is no any word in manuals regarding this..
Thanks,
Dmitry

I have attempted this in the pass. I'm not sure about the term "trickle feed".
But the technique that I had the most success with was:
import database sample.basic data
from data_string
'"Sales" "COGS" "Marketing" "Payroll" "Misc" "Opening Inventory" "Additions"
"Ending Inventory" "100-10" "New York" "Jan" "Actual"
678 271 94 51 0 2101 644 2067'
on error abort;
Your automation process can build this string in real-time. You might want to setup committed access to a BSO cube, just in case you need to have rollback capabilities.

Trickle-feed Mapping

Hi gurus,
Do you have any experience on developing a trickle-feed mapping in OWB 11gR2?
It'd be appreciated if you could kindly share it!

Unable to Deploy an ASO Essbase cube in EPMA

Hi All,
I am having issues while deploying an ASO essbase cube application in EPMA.
1.Have created a new Essbase ASO cube application
2.Created an basic outline about 10 dimensions
3.Validated it successfully
4.When i deploy it starts the initiation and after sometime it comes up with Below Error message
Detail: Initiating product Action
Generating Headers and callback information
Posting Product request
Connection timed out: Connect
I have created an Empty ASO application and selected the sot order..It validates fine, But unable to Deploy..same error message

This issue is seen only with IBM JDK 1.6 (any SR) because, IBM packages the xerces version 2.9 as a part of $IBM_JDK_HOME/jre/lib/xml.jar.
I think/understand that, your application is also packaging a xerces impl jar(different version otherthan xerces version 2.9) in WEB-INF/lib of you application.
So, to make sure that the WebLogic Server uses the xerces impl jar that has been packaged, you are trying to use the filtered classloader in weblogic-application.xml
But the filtered classloader would not have any effect, since, the IBM JDK packaged xerces parsers would also be with the same package structure. So, I think you should try with setting the following in WEB-INF/weblogic.xml inside the <weblogic-web-app> tag.
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
I think this should work with WLS 11gR1PS2 (WLS 10.3.3).

Spotfire POC using ASO Essbase data source

Looking for anyone with success using Spotfire on Essbase, specifically ASO storage type. We're performing a proof of concept, testing Spotfire 6.5.2 using Essbase 11.1.2.2 as a data source. We've been able to connect without any issues and visualize some data. We have several calculated measures in Essbase that are not being visualized in Spotfire. When we select these measures we receive the following alert: “The query is not supported in the external data source. External error: It is not possible to aggregate the measure 'ACC' in the current configuration. The aggregation would be based on an Essbase formula that is not guaranteed to be additive.”
Does anyone have experience connecting spotfire to essbase, I would like to hear your feedback and lessons learned to help us jump start our effort.
Thanks in advance for your feedback.

Hi Sayak,
Let me know if I got you right, that you have a Priority as an account member in Essbase with the members 0,1,2 which you are trying to report as 'LOW', 'MEDIUM' and 'HIGH' through OBIEE.
Ok, If it is so, here are some pointers
1. If I go by your example, I still cannot see PRIORITY as a measure, instead I would consider this as a Dimension (might well be an Attribute Dimension to be precise)
2. For some reasons, if this is still a measure here are some steps what you could do (I could not test these though, but hope you can get it right when you run through them)
Import your Essbase outline to OBIEE and your relational lookup table too in the physical layer..
Convert the Essbase measure dimension to flat measures in physical layer. Yes, just because you got to have a lookup for this priority measure exclusively and I do not think we can do it, with the account still as a hierarchy in OBIEE.
Once, you pull the Essbase cube into BMM, you could see the Fact table for the Essbase cube with this priority measure.
Create the lookup logical table too in BMM, using this physical lookup table.
Now for the Priority measure in Essbase's Cube Fact table, you could use the Lookup function as below
LOOKUP
SPARSE/DENSE
#Logical Lookup table's description column here #,
#Essbase's Priority Measure
Just give it a try, I am sure you will find a way through. Hope this helps.
Thank you,
Dhar

OWB Trickle Feed Mode

Just attempting to replicate some de-que functionality currently encoded in PL/SQL using Oracle Object Types as the transport mechanism for the AQ.
Following David Allans blog reveals a few issues:
http://blogs.oracle.com/warehousebuilder/2009/09/owb_11gr2_trickle_feed_data_acquisition_and_delivery.html
The first is that the Single Subscriber Queues are not being imported by OWB but the Multi Subscriber Queue is, the second issue is that the mapping will not compile using the Multi Q and an error is returned:
VLD-4257: The real-time driver queue RECON_Q is not a streams queue
Select a streams queue as the real-time driver queue
Any ideas? I know this is 11.2 frontier stuff.

Hi Paul
These are some odds and ends I have found behind the reasoning. There are several limitations using a single consumer queue. Some of them are
* You cannot add subscriptions (or subscribers) to single-consumer queues.
* To be able to add recipient and subscriber , the queue must reside in a queue table that is created with the multiple consumer option. Remember that the recipient list over rides the subscriber list and allows producers to control message dissemination.
* You can propagate messages from a multi consumer queue to a single-consumer queue. The reverse is not possible (as far as I know at least until 11gR1).
* Consumers of a message in multi consumer queues can be local or remote.
* Multicast and broadcast models not feasible with single consumer queue.
* In 10g and later (I think) , Queue monitor removes messages from multiconsumer queues. This allows dequeuers to complete the dequeue operation by not locking the message in the queue table. This got rid of the only sore point for multi consumer queues.
Single consumer queues are cookie cutter solutions between two applications that exclusively talk to each other and have no use beyond that. The multi consumer queues are more versatile.

Data load in Essbase ASO cube

Hi,
I have not been using ASO cube before and had worked only on BSO cubes. Now I have a requirement to create a rule file to load data in to an ASO Essbase cube. I have created a data load rule file as I was creating for a BSO cube which is correctly validating. However when I am doing the data load I am getting following warning:
"Aggregate storage applications ignore update to derived cells. [480] cells skipped"
I have investigated further and found that ASO cube does not allow data loading at upper levels & on members calculated through formulas. After this I have ensured that I am loading the data in to zero level members and members which are not calculated through formula. But still I am not able to do the data load & getting the same warning.
Could you please help me and let me know if there is anything else which I am missing here?
Thanks in advance...
AKW

Hi AKW,
"Aggregate storage applications ignore update to derived cells. [480] cells skipped"This is only a warning message that means only those many cells were skipped might be for some reasons like any member pointing to those cells will be missing.
If you want to copy the Data of your BSO cube to an ASO Application why dont you use an PARTIONING it will copy your whole data from BSO to ASO (If Outline is common in both then copy any member of Sparse dimension like "Scenario 1" from Source i.e. BSO, to same member like "Scenario 1" in Target i.e ASO ),
This is only an alternate wayThanks

Best way to keep Essbase data available at all time

Hi all,
We are trying to find out the most suitable way of designing our Essbase cubes so that the data is available to user all the time even during data replication and aggregation.
We may have aggregate the cubes every one hour and cubes will both ASO and BSO.
Can someone give some direction on this? Can we use trickle feed for ASO and or clustering is a better option? Also what kind of clustering will be best suited for this?
Any other tip wlll be really helpful.
Many thanks.

U do not need aggreate ASO
becouse all agregates calc automaticaly with user retrive process . But u may have to use material view for store most popular report on storage.
Please provide more details
1) What you decision - Budgeting or only Reporting
2) How many interactive concurent users
3) How many members in mesures, count of dimensions, count members in dimensions,levels in dimensions
What are reporting tool u using ?

Non-admin user cannot access Essbase server level variables

Version 11.1.1.3
Essbase Substitution variables are created at server level. Users are getting error in FR report that uses the Subsitution Variable -- Essbase Error(1051085): You do not have sufficient access to get this substitution variable. Also, users cannot access Substitution variable in SmartView. However, users can access variables created at database level. Users are provisioned as "Server Access" to Essbase and filter access to ASO application "MGTRPTG", where MGTRPTG is an ASO essbase application for reporting. We tried the same provisioning in two other environments and it seems to be working fine.
User is type "Essbase and Planning" provisioned with essbase "server access", application mgtrptg "filter", Reporting and Analysis "analyst", "dynamic viewer" and "Explorer". In addition, it is given a filter "REP_DME_GALB" which restricts 2 dimensions (Division and Geography).
Steps taken to resolve:
1. Existing users were deprovisioned and reprovisioned with no effect.
2. Created brand new identically provisioned users in Prod and QA. QA user can access the server level var and Prod user cannot
3. Created a brand new server level variable in Prod and this cannot be accessed.
4. All services have already been restarted several times.
5. SR has been opened.
Temporary workaround:
By creating a duplicate of the same set of variables at the database level, the reports work. This can only be a temporary workaround as the client cannot be expected to maintain two sets of substitution variables since there are 3 applications using these server level variables.
Thank you for any ideas!
Jennifer

You have stumbled on a defect which is resolved in the Hyperion Planning 9.3.1 patch 6 and above. If you have your planning preferences set to indent members it will cause forms which have page selections to show as invalid in SmartView.
You can either patch Planning or turn off the preference. The patches are available from http://metalink3.oracle.com and require account which has been associated with your client ID.
P.S. Usually it's not a good practice to use the admin id.
Regards,

Loading data using send function in Excel to aggregate storage cube

Hi there
just got version 9.3.1. installed. Can finally load to aggregate storage database using excel essbase send. however, very slow, especially when loading many lines of data. Block storage much much faster. Is there any way you can speed up loading to aggreagate storage data base? Or is this an architectural issue and therefore not much can be done?

As far as I know, it is an architectural issue.. Further, I would expect it to slow down even further if you have numerous people writing back simultaneously because, as I understand it, they are throttling the update process on the server side so a single user is actually 'writing' at a time. At least this is better than earlier versions where other users couldn't even do a read when the database was being loaded; I believe that restriction has been lifted as part of the 'trickle-feed' support (although I haven't tested it)..

Hyperion Financial Reporting - Export to Excel converting Data to Text

We are using Hyperion Financial Reporting 11.1.2.2 with Hyperion Workspace 11.1.2.2 reporting on an ASO Essbase cube version 11.1.2.2.
When we export a report to Excel any data values that are displayed in the report with a negative ('-', '()', etc.) sign come into Excel as a text value. The cell has the green flag and the single quote in it denoting this a text field. The format is listed as 'Custom'. Updating the format does not remove the single quote.
The same result is happening if we display the natural sign in the report or if we flip the sign in the report. This DOES NOT happen when choosing the export query ready, only when using the File -> Export -> Excel.
Does anyone know if there is a hot fix or service pack or configuration to resolve this? How about a work around?
I thought I remember this happening in 9.2 and being resolved in 9.3. We have recently upgraded from 9.3.1 to 11.1.2.2 and the issue is happening again.
The users would like to export the formatted report to Excel and be able to interact with the data cells as numbers.

The issue is reported as a bug. Installing patch 14625370 (11.1.2.2.302) and/or 16088101 (11.1.2.2.303) should fix the problem.
