Calc dynamic vs calc and store dynamic members upon request of the scorecard.
HelloI understand the dynamic use of calc and dynamic calc and store, but I have my doubts about the use in applications of scorecards. Usually, these applications have a predefined queries, so all the users navigation guided by the cubes. So in this case, what do you use dynamic calc and store?
I think that the first executions using domain controllers may be slower that uses dynamic calc, but generations retrieves DCS should be faster because the members were calculated.
What do you think about this?
Thanks for your help.
Please, excuse my English.
You're right, that philosophically, it comes down to whether or not you will re - use data a lot.
If not, then it only adds problems to use DCS vs DC (problem #1: written additional block and further fragmentation = overall less optimized).
However, if you do the kind of analysis where the chances to dig deeper are higher than the chances of digging at all, then DCS is logical. Let me explain: you can not ever recover this data, but that you do, it's for a reason that will inspire more investigation.
Can you think of a case where this is? I can, as you said - dashboard and dashboard applications. If they are looking, it is likely, because there is a problem and they will look a lot deeper. In this case, the price paid once is better than time and time again.
That said: most scorecard applications tend to focus on several metrics specific and limited initially, which usually means that demand is nimble enough, if you don't really win by going with DC/DC members. If your application is slow, it can help, but it will not be the quick fix (at least compared to other responses).
Bottom line: Yes, DCS has its place, and sluggish forward-looking cubes are a place that you might want more than others.

Calc Dynamics Processor cannot allocate more than 350 the heap block of
Dear users of Essbase,
I am trying to implement some logic in order to get my calc done by dynamic calc and formula on members.
My dynamic member calc with formula is not limited to offsetting the conditional statement to the role of alternative only, I see no problem.
But in order to get the correct result, I include under condition ISMBR statement and restrict level 0 patch replacement on a sparse Member, I get this ' error Essbase (10127000): dynamic calc processor cannot allocate more than the blocks [350] from the jump. The parameter CalcLockBlock is too low or the size of data cache setting is too low. Increase the setting of the CalcLockBlock or the size of data cache setting and then try again '
IF (@ISMBR (@RELATIVE("ALTERNATIVEROLLUP",0)))
IF (@ISUDA ("SCENARIO", "XXX"))
do something...

I looked through this forum and tried to fix my problem in making changes on Essbase.cfg of DATACACHESIZE and DATAFILECACHESIZE values.
I also checked in the settings of CALCLOCKBLOCK and the error message shows his tent to allocate more than the default value no. blocks that is 350 blocks in my tests.
I have CALCLOCKBLOCK with HIGH as 4900, settings default than 350. Hope this is good enough.
As it is on the dynamic calc and formula approach based on, would like to know how to face this question set.
If you have encountered this problem would like to take suggestions. Thank you.
Kind regards

Of course, JM, it was my test script.
I would like to change my script to be the best :-).
And I could get rid of the Essbase error in improving more all hides and CALCLOCKBLOCK parameters.
The operating current system cann't be changed to try chaning type of dimension and other changes required for the TBLAST property. It is one of the obligation that I work. Then try my best to correct and come out with the best solution.
It is easy to build the new app with fresh demands to try to include new features to the existing system.
Thanks a ton for your time and your suggestions.

Which a member property of 'Storage' to 'Dynamiccalc and Store '.
Hello
I'm curious to know if there is a problem with the existing data if I change a member of 'Store' to 'Calc and dynamic store '?
Thank you!Do you plan to put it in a dense beam? If so, realize that whenever you are recovering, you will almost certainly be fragmenting your db.
I have (for what it is worth, and is not a lot) never used a dynamic calc and store. Maybe I need to get out more, but I didn't feel fuzzy.
Kind regards

How do I download an image from a server and store it in EncodeImage
How to download an image from a server and store it in EncodeImage?
It allows you to create an EncodedImage object. so that you can upload an image from a server, you can use HttpConnection to send a request to your server. Then, your server can return the image file. Since he will cross the stream, you can read and store it in a "byteArray". so the ByteArray, you can generate an EncodedImage by calling the EncodedImage.createIncodedImage (byteArray). now that you already have a coded picture.

R31 reading SDK / links library and store SDK
What are the links to R31 SDK of reading and library and store SDK?
Ideally the JsDoc pages include JavaScript download?
For example:
Kit development software in the store and the library:

- R30: Adobe DPS - library and store SDK 2.30: Index of the class: JsDoc reference
Reading SDK:
- R29: Adobe DPS - reading SDK 2.29: Index of the class: JsDoc reference
- R30: Adobe DPS - reading SDK 2.30: Index of the class: JsDoc reference
You must use our devnet as the reference site for where to find things: Digital Publishing Suite | Adobe Developer Connection. The link at the bottom of the page points to the SDK library and refers to the new version. You can also use http://www.adobe.com/go/dps-library-store-api to always get the latest version.

Dynamic members of calc &; store are not copied on another escenary
Hello:
I have a dimension (Business Unit), where several members of level 1 are "dynamic calc & store.
If I copy a 'draft budget' staging data for another staged 'budget', sometimes some values in members of this "dynamic calc & store" are not copied (they show #missing in 'budget'). All the data of level 0 is just. Also, level 1 in Member data is stored. Most strange is that some calc dynamic level 1 & store members are also copied.
-Is anyone knows why is this happenning?
-Is it possible to avoid this?
-What happens if I change the ths dyn calc & store stored members? It will change the data?
Any suggestions would be very helpful for me.

My query is related to the link below...
Business Rule _ on calc dynamic members
Now, I made TOTAL members to store data... TOTAL of cells being store in webforms his showing as write celll... threre is a chance that users can enter data and save it... How can avoid this confusionYes, it is a good approach and works very well. However, as John suggested, you can enable security on the stored member and get what it read-only. This could be a better approach.
See you soon,.

cross dimensional operators on calc dynamic members
The dimensions of my product and market are stored dimensions used in a calc script in AccountX calculation as follows:
"AccountX" = "AccountB"->"product"-> "market"->"organization";
I would like to change the dimensions of products and market to dynamic calc, but wonder if it would affect involuntary the calculation above, I would like to remain the same.
In other words, can I use Crusaders dimensional operators on calc dynamic members without any problems?In principle you can cross-Sun dynamic members Calc, but this can have an impact on the performance of recovery especially if product / market are (and I assume they are) sparse dimensions.
You must carefully test performance / calc order impact etc. in any case if you do what you suggest, which is much larger than any impact on this script formula especially calco - but I guess you know who.

Dynamic number of columns in the table
Hello
I use JDev 10.1.3.3.0 with ADF. I just want to create a table, with a dynamic number of columns in the table. The background is that a user of my webapplication can create and submit a sql query. Now, I have to show him the results. My idea was, I have save the result in a bean managed (ResultTable), which is stored in the session context and map at my table in my page.
If I search the Forum and don't get only one useful thread: {: identifier of the thread = 971888}, but I don't exactly understand. What is the CollectionModel? Do I need this?
I'm trying to report on the following:
ResultTable
ResultColumnpublic class ResultTable { public static final String SESSION_NAME = "ResultTable"; private ArrayList<ResultColumn> columnList; private CollectionModel collectionModel; public ResultTable() { } public ArrayList<ResultColumn> getColumnList() { return columnList; } public void setColumnList(ArrayList<ResultColumn> columnList) { this.columnList = columnList; } }
ResultTablepublic class ResultColumn { private ArrayList<ResultRow> rowList; private String name; public ResultColumn() { } public ArrayList<ResultRow> getRowList() { return rowList; } public void setRowList(ArrayList<ResultRow> rowList) { this.rowList = rowList; } public String getName() { return name; } public void setName(String name) { this.name = name; } }
My showResult.jspxpublic class ResultRow { private String value; public ResultRow() { } public String getValue() { return value; } public void setValue(String value) { this.value = value; } }
The ResultTable was filled with data, but the Board is not filled. So, I think, it must be rejected to the data binding.<af:table emptyText="No items were found" value="ResultTable.columnList" var="column" varStatus="colStatus" id="table1"> <af:forEach items="#{column.rowList}" var="row" varStatus="rowStatus"> <af:column sortable="false" headerText="#{column.name}" id="column#{colStatus.index}"> <af:outputText value="#{row.value}" id="outputText#{rowStatus.index}"/> </af:column> </af:forEach> </af:table>
I get warnings and errors to run too. But I don't know if they are the result or cause of my problem.

MajoHi Mario,.
Note that your JSPX snippet above has serious shortcomings:
- 'ResultTable.rowList' is not an EL expression, but the value attribute of the af: table must refer to an EL expression
- Items AF:foreach = "#{row.cellList}"-you don't have to store information about the columns of all rows, more it won't work as af:forEach tag may not see the value of the expression of EL #{line} (or any component EL expression created). " See the tagdoc here: http://www.oracle.com/technology/products/jdev/htdocs/partners/addins/exchange/jsf/doc/tagdoc/core/forEach.html
- "ID =" Column #{cellStatus.index} "and id =" outputText #{rowStatus.index} "are invalid and that they don't compile even as id attributes cannot contain EL expressions.
.
I think to solve your problem, you need three things:
- List of columns (for example the list
If you need to store only the names of column or list If you need additional information),.
- list of lines,
- a line can be a map (with the name of the column - cell data mapping; card e.g.
) or a list (with columns indexed; for example - list of lines,

How can I get a dynamic mic to work on the iMac?
How can I get a dynamic microphone to work via the usb input? Do I need a plug-in?
Well Yes, if it is a USB microphone, the support is to plug. Note, Apple provides an Audio configuration and Apple Midi utility in Applications-> utilities that once connected develops on the parameters in the menu-> Preferences-> sound-> entry
Some microphones require Mac OS X drivers. It would therefore be important to determine if yours is a. Google your brand and model micro with Mac OS X and the drivers of Word to see if someone needs.

How can I change example full pwm to make dynamic frequency as well as the cyclical report?
Successfully, I downloaded and compiled 'daqmx_pwm_examples.zip '.
of http://www.ni.com/white-paper/2991/en
and he has run in LabView. I know it works because the oscilloscope properly displays a waveform of pulse with the desired program in the frequency and duty.
I noticed while the program is running, if I decide to change the operating factor that it updates dynamically the waveform of pulse on the oscilloscope. However, if I change the frequency while the program is running it does not refresh in the oscilloscope.
I think it's because the duty cycle is hung in a "shift register" while the frequency is not.
I tried to plug the frequency in an as well shift register, and I was wondering if I could get some advice regarding the simplying or correction of my circuit diagram of the back panel shown here:

I would be very happy / any Advisor.
Thank you.
Still a few ugly son (particularly wire error that buckle under the structure of the case), but seems to be well. I'm not really sure what you're asking - you still have a problem with it, or it does not work as expected? Have you tested it?

Speakers of the laptop to listen to music very well. When I use the headphone music in my headphones has a dynamic range very little. The sounds of music crushed. The strong parties are limited and the soft parts are high until I can hear background noise in the recording. I've never had this problem on any other PC.
I'm listening on iTunes, Soundforge, and any other audio program.
I downloaded an updated version of the software for the sound card - that solved the problem.

Name of the dynamic property of object in the table based on the value of a variable
I have two paintings of custom class objects
var obj1:Object1 var obj2:Object2 var array1:Array = [obj1[0], obj1[1], ...] var array2:Array = [obj2[0], obj2[1], ...]
Object1 has a property named. Name while Object2 has a property named. Title.
Now I have a common function including cab accepts an array (array1 or array2) and the name of property the object ("Name" or "Title") as input and needs to access this name of the property of the objects in the array:
function myFunction(arr:Array, fieldName:String) { arr[0].fieldName = "xxx"; }
the problem I have this achievement does not because the code in the function assumes that the property of that object in the table is actually a string "fieldName" while I want to dynamically determine the names of the fields based on the value of this variable, but cannot understand the syntax to do!
Don't know if I'm clear - hope that makes sense... ;-) Thank you
Hey p3pp3r,
I think I understood you. Try the following and see if you get good results:
function myFunction(arr:Array, fieldName:String) { arr[0][fieldName] = "xxx"; }
Let me know how it turns out. Good luck!

Mappings of dynamic interface of SSID in the AP groups
Hello, I have a few questions about the mapping of the SSID to the interfaces within the AP groups. My controller runs 7.4.110 and has about 150 APs configured on the controller.
5508 pair UNIQUE for all APs authentication mode
50 are on the same campus as a controller. (APs in Local Mode)
100 are 40 other WAN sites. (APs to FlexConnect Central, site based authentication DHCP)
3 SSID broadcast to all sites
Corp - 802. 1 x
Warehouse - Auth WPA2-PSK-Mac
Reviews - wide opening with a Cs & Ts that you accept very similar to a hotel
Controller interfaces
Management interface
The warehouse - dynamic interface
Customer interface - dynamic
I have set up groups of AP for each remote location. My question is this:
For these places distant in the AP group configuration, should I maps all the SSID to the management interface, or I should map it to the dynamic interface? I.e. to Corp.--> Management, warehouse--> warehouse, guest--> comments.
For local access points, I do the SSID mapping for each interface, but I don't know that it's important for my remotes.
Help is greatly appreciated.
For your remote offices FlexConnect APs.
If WLAN is configured for local switching, then users will get IP of the interface that you corresponding in the mapping section vlan in the AP configuration. (interface by default yield under general WLAN or the AP group WLAN configuration section is not a problem)
If WLAN is configured for central switching, then you must assign a correct dynamic interface under the WLAN-> General section or AP group WLAN configuration.
