Hide partition and attribute dynamically
Hello everyone,
We can hide partition & attributes manually by using AttributeHierarchyVisibility Property from False.
but can we hide these all at process time or dynamically.
Thanks in advance.
Regards,
Jvora
Hi jvora,
According to your description, you want to dynamically hide partition and attributes. Right?
In Analysis Services, the only way to hide the attributes is setting the AttributeHierarchyVisibility to false. It's not supported to apply any condition when setting this property. Also for processing dimensions and partitions, it's not supported to
skip attributes during processing. You requirement can't be achieved.

Data not replicated with partition and dynamic calc
HI
I am using Essbase 11.1.2.1.
I want to use a replicated pratition wetween two Essbase BSO applications.
But in my source application, I have to send an account ACCOUNT (level 1) with several stored members and 1 dynamic calc member with formula. Due to this Dynamic calc account, the partition doesn't work (data are not replicated).
How could I do?
Thanks
FannyYou're right, dynamic calc account are not issues. I am using them in partition.
But py issue is there :
The source dimension is like this :
TAX (Dynamic Calc)
- 6xxxxxxx
- 6yyyyyyy
- 6zzzzzzz (Dynamic Calc) = formula
The target dimension is like this :
TAX
And so I need to send TAX (Source) to TAX (cible).
I don't think it is possible, but I would like a confirmation before using something else.
I hope it is clearer now.
thanks

Transparent partition and Dynamic Calculation
I've setup a target cube which collect the results from two different source cubes: one for historical data, the other one for the current period. I've put formulas on accounts in the target cube. Those formulas refer to both historical and current periods. Those accounts are also set in the source cubes as dynamic calculated. But even by setting them as stored members, the target dynamic calculated members do not take the precedence. How to solve this ? <BR><BR>Stéphane

In other words, limit the scope of the accounts dimension in the partition so that none the dynamic calcs are in the source of the partition. This means making a subset of the accounts dimension that includes only those accounts with data and not those that are dynamically calculated.<BR><BR>If you have an accounts dimension with three members: COGS (loaded), Sales(Loaded), and Margin (dynamic calc: Sales - COGS), the source partition should only include COGS and Sales, not Margin, allowing the margin calculation to occur in the target cube.

Last edited by Elias Blinow (2013-10-24 14:54:31)First of all, welcome to the forums! I hope you enjoy your stay.
Second, have you read the forum ettiquete? It is probably a good idea to get yourself acquainted with the rules and expectations of this partular forum, partly because they are somewhat different to what you may have encountered in the past.
In particular, there is the expecatation that users who ask for help will have done their own research. I'm not saying that I know for certain that you didn't google the issue. But you didn't give any hints as to what information you might have found if you did. We are certainly here to help with issues you may have, but that doesn't mean that we will sit here and feed you answers, but rather we hope to guide you in finding the answer for yourself. Hopefully in this way, you can start to learn where to look when future issues arise.
Regading your issue, a quick google search of "linux hide partitions" yields many answers. The first hit (for me anyway, as google's results are customized) seems to indicate that udisks can handle this with a simple udev rule. -
Urgent help ----problem of component id and attribute value
I want to produce a dynamic menu that compoment id and attribute value will be dynamic assigned when logon to system. That means i have to use id="#{aid}" and value="#{avalue}" in following codes.
The problem are:
1. Component id looks only accepts constant (hard code data) insteads of varable. I changed id="ADMIN", and it works. It can be empty, and tag will give me one. Therefore, it is not too much affected me.
2. The f:attribute value, when value="Value" works. However, when value="#{avalue}", first time works, second time it throws Illegal State Exception. I really need this value be assigned by varable.

Data Recovery from Partitioned and formatted Bit Locker Encrypted Drive
Recently because of some issues in windows 7 installation from windows 8 installed OS. it was giving as the disc is dynamic windows can not be installed on it. so at last after struggling hard no other solution i partitioned and formatted my whole
drive so all data gone included the drive which was encrypted by bit lockers.
For recovery i used many software such as ontrack easy recover, get data back, recovery my files professional edition but still i couldnt able to recover my data from that drive. then i found some suggestion Using CMD to decrypt my data first
http://technet.microsoft.com/en-us/library/ee523219(WS.10).aspx
where it shows it successfully decrypt my data at that moment my drives were in RAW format excluding on which windows is installed and then in CMD i check Chdsk which also shows no problem found. but now problem is still i coudnt able to recover
my data then i format the drive D and again tried to recover data using above software after decryption still no result.
Now i need assistance how i can recover my encrypted drive as it was partitioned and also formatted but decrypted also as i have its recovery key too. thanksHi ,
I am afraid that we cannot get the data back if the drive has been formatted even if use the
BitLocker Repair Tool.
You’d better contact your local data recovery center to try to get data back.

How I tried fix my partitions and restore a Dell Diagnostic Partition.
UPDATED: 2 September 2012
UPDATE: Now that I reflect back on the incidence, I realize that the Dell Utility partition had lost its ability to boot long before I had messed up my partition table. But I realized it only when I was testing all my partitions after fixing the partition table. But as I have already written this long post, lets just keep it here for future reference of anyone else stumbling across a similar problem. Read on to know about my experience.
RECOMMENDATION: I do not recommend trying out all the steps below as they did not completely solve the problem for me. If you need the Diagnostic Utility, download the update package from Dell's support website for your model. This package can be used to create a boot-able USB drive and/or CD/DVD. These work fine and are pretty fast also.
Something strange happened to me and I am now reporting my experience in trying to solve it (somewhat unsuccessfully!!)
First of all, my setup is: Dell Studio 1555 laptop. I dual boot Windows 7 and Archlinux. So here's how it went:
After using the partitioning tool Gparted under Archlinux to resize a partition, I found a problem had occurred. The Partition was NTFS formatted and all of my data files were stored on it. The partition worked fine under Archlinux as I was able to access my files fine under it. But in Windows, although the partition was listed under Windows explorer, it wanted to format it!! When I tried to access the partition it gave an error that it was not formatted (
The drive is not formatted, do you want to format it now?
). Of course, that was not right and Gparted had messed something up. I fixed that using Testdisk under Archlinux (See the Details). So now the partition problem under windows was fixed. But now another problem cropped up under Archlinux. When I booted into Archlinux and started Gparted to confirm everything was fine I saw something strange in Gparted. The whole space on my hard disk was marked as "unallocated" under Gparted. Windows and Archlinux could "see" the partitions. By this I mean that I was able to boot fine under both my OSes. And I could access all my files under all my partitions. But somehow Gparted was not able to "see" them. Gparted was reporting my whole disk to be marked as unallocated. After that I researched a lot and lots of stuff happened experimenting to fix the problem. I used a lot of utilities. But actually only one fixed the problem-fixparts from the gptfdisk package. But it seemed like a lot of work trying to get the problem fixed (See the Details).
Now we get to the point in discussion. I was able to get my partitions back under Gparted. But I lost the Dell Diagnostics Utility partition's ability to boot up. [Actually, now that I reflect back on the incidence, I realize that the Dell Utility partition had lost its ability to boot long before I had messed up my partition table. But I realized it only when I was testing all my partition after fixing the partition table. But more on this later.] It gave an error that the partition was not found.
So, in short: After all this restoring partitions' visibility under Gparted, I realized that the Dell Utility partition on my Studio 1555 was not booting up. To explain this, it means that when I press F-12 when starting the laptop and select Diagnostics from the menu to run the Diagnostic Utility and after running the Pre-boot System Assesment tests when I consented to boot the Diagnostic Utility partition, it gave me the error that the partition was not found. When I tried to run the "Dell 32 Bit Diagnostics (Graphical User Interface version)" update package under Windows, it resulted in a similar error: Partition not found.
For some background on what makes the Dell Utility partition so special, please read this thread and the third post on this thread.
WARNING: You and only you are responsible for your data. Please make a backup before performing any of the partitioning steps below.
NOTE: Please read the entire post before actually performing the steps.
So, to try and fix this I did the following:
Boot into Windows 7.
Open Disk Management under the Computer Management console (To open the Computer Management console, right click on Computer in the Start menu and select Manage).
Reformat the Dell Diagnostic Utility partition as FAT(not FAT32). This is the first partition on the drive (marked as Healthy (OEM Partition) under the Status column). [This step may not be required, however I had done it. See Notes below.]
UPDATE: After reading around a bit I found that these steps to format the partition might not actually be necessary. Simply changing the type of the partition (as detailed below) might also work. However as I had done that, lets just keep these steps over here.
Reboot into a Linux distribution Live CD (I had Ubuntu 10.10). Or, If you dual boot with a Linux distribution that does not complain about the now inconsistent fstab entry, you can also boot into that distribution directly. I had to boot into Live CD to fix my /etc/fstab.
UPDATE: After considering all the aspects from start to end I have come to a conclusion regarding the efficacy of this method on dual boot machines with Windows and Linux installed. I doubt anyone with a dual boot Windows/Linux setup would be able to boot into the Dell Diagnostic Utility even with the Utility Partition restored. This is detailed below.
(As noted above my Archlinux install did not boot up after I had reformatted my Dell Diagnostic Utility partition. This is because I was mounting the Dell Utility partition at boot using fstab inside Archlinux. And I was using the UUID to mount the partition. After reformatting the partition its UUID changed. So, it wouldn't mount. And because of how my fstab was setup Archlinux won't boot. So, I had to boot into a live environment to fix this. This step applied only to me. YRMV.) Fix the fstab entry.
(This step also applied to me.) Boot into the repaired Linux Distribution.
And open a Terminal.
In the open terminal run fdisk on your drive, e.g.,
fdisk /dev/sda

Download the required Diagnostics Update Package from the Drivers Download page for your model. Got mine from here.
Run the downloaded package under the OS you it downloaded for. That is, run the .exe on Windows. Or, if you downloaded the .bin file for Linux then first make it executable:
chmod u+x CL1367A0.bin
And now run it under a Linux distribution with an older version of python installed (I think <2.7). I say this because the .bin package didn't run on an updated Archlinux for me, probably because it has the latest python. I ran it from the Ubuntu 10.10 Live CD and it ran fine under that.
On Windows, If you are not automatically prompted with an option to update your Utility Partition then you need to browse to the location where the package was extracted (for me it was C:\dell\drivers\R239866).
Now you need to manually run the extracted file (for me it was DDDP.exe). Most probably you'll need to right-click it and run it as an Administrator. And if all went well, it will extract/update the diagnostic utilities to/on the Dell Utility Partition.
I believe the above steps should be sufficient for someone who's lucky and who's update package is smart enough. However these steps were not sufficient for me. My "Partition not found" error was gone because I had changed the partition type. And so the update package was able to recognize the partition and extract the necessary files to it. But I was still not able to boot the utility partition. After the Pre-boot System Assessment although I no longer got the "Partition not found" error, but I was just dropped onto the GRUB boot menu prompt.
[UPDATE: As stated above, I realize that the recovery partition had lost its ability to boot long before I had messed up my partition table. But I realized it only when I was testing all my partition after fixing the partition table. Please refer to this forum thread for further Details. I do not think that it is possible longer to boot from the Dell Utility Parttion on my setup which has GRUB installed to the MBR. But the rest of the post documents my attempts to slove the problem without the knowledge from the forum post.]
Anyways, it was a pain to again and again set up/update the partition and test it after waiting half an hour or so for the Pre-boot System Assessment to complete. But I was determined to solve the problem at-least partially, until next time. So I created a GRUB entry to boot the Utility partition. Assuming the partition is the first partition on the drive (which is the case here), the grub entry is simply:
title Dell Utility
rootnoverify (hd0,0)
chainloader +1
I tried downloading an older update package. I updated my Partition with it. And tested. Still, I was unsuccessful. I researched a little bit and found this link. Out of frustration,I decided to use brute force this time . So, the below are the steps which let me have at-least a glimpse of The Dell Diagnostic Utility booting up from the partition:
Backup your partition table using the sfdisk command (not fdisk).
Follow the instructions in the link I gave above (i.e., http://community.spiceworks.com/how_to/show/1123) and build your Utility Partition from scratch.
Now after that when you try to boot into the OS you'll be presented with an blue bar on top. This is because the mkup batch file from the Dell Diagnostic/Drivers CD/DVD wiped your partition table and rewrote it with only one partition on it- the Dell utility partition.
Boot into a Live environment and restore your partition table from the backup created earlier using sfdisk.
Now boot with a Windows disc to repair your Windows boot problem. This applied to me but may not apply to you.
Again boot into a live environment and restore GRUB to MBR.
After a reboot press F-12 to get to the BIOS boot menu and select Diagnostics.
Let the Pre-boot Assessment run and after its complete it will ask you to press any key to boot the Dell Utility partition. Do that.
You'll notice your still dropped into GRUB instead of getting the Diagnostics GUI.
Now when on GRUB prompt don't boot any other OS.
Press any key (other than <Enter>, that is ) to stop the timer if you have one set.
Now look carefully at the boot menu.
Remember I told you that I had created a GRUB menu entry to boot the Dell Utility partition. Select that. And if you are lucky you might just be able boot the partition. This worked for me (finally!).
After this initial run I was unable to run the Diagnostics GUI from the GRUB menu entry again. I haven't tried to re-run the Pre-boot Assessment and wait to see, if I'm able to boot it from there. But now, I'm satisfied that at-least the file there are in a running condition.
Also, the update package can be used to create boot-able USB drives or boot-able CD/DVDs which can run the Diagnostics just fine. They are almost as fast as the partition (especially the USB which seems even faster). They are recommend, instead of going into this trouble to recreate the partition. That is unless you are a purist/perfectionist .
Notes:
At first, I panicked and tried a lot of steps that are not exactly documented above for the sake of convenience to others who might refer.
I have thus rewritten the post in a manner to make it very general in nature as it did not become very fruitful for myself. If you attempt to use this guide, use common sense where necessary .
Of course, if you are trying to build a Utility partition on a bare hard drive or you're feeling adventurous, you can always follow this link .

The file seems to create the CD/DVD/Image and USB just fine. So I used this only to create a CD image which I then wrote on a blank CD which seems to work fine. Also, I played around a bit and had some partial success in booting the partition. I've updated my original opening post with the new findings.
Whew!! what a waste of time! Never want to do all of this again .

Excel and Word dynamic VIs broken
I upgraded from Labview 8.5.1 to 8.6 and tried to upgrade the microsoft office report generation toolkit at the same time but got an error as I am using office 2000 (not compatible with the new toolkit). Now, I can add the word and excel dynamic VIs to a project and add them to an application build but when I try to build the exe I get an error saying the word and excel VIs are broken. Looking at the Excel VI shows an error "SubVI 'NI_Excel.lvclass:Excel_Get_Properties.vi': required input 'report in' is not wired". The Word VI gives three similar errors. Is there a known problem or workaround for this?
Hi zeppelin_79,
Can you provide me with the screenshots of the error?
From my experience, Common error came up when we upgrade the Microsoft Office versions. Since, different version of Microsoft Office might have different attributes that being access by the Report Generation Toolkit for Microsoft Office.
In the meantime, try to do what this article recommended:
Broken Run Arrow When Using Excel Get Data VI in My Application

Let me know if the problems are still persist.

How to hide/show and move screenelements at runtime
Hi Guys
Currently, i have a requirment that, in the same screen, when user choose different different option in the dropdown list, there should be different screenelements and table control with different columns showing below it.
Now, i have two plans below:
1), hide/show and move position of screen elements and table control at runtime
2), call different subscreen
I hope i can take the first way since the second way will modify structure of program ( As it is infotype screen ), any one knows how to implement the first solution?Hi,
I would suggest you to call different subscreens and load them dynamically based on your parameters.Since different subscreen are called your coding and functionality could also be seperated by writing in the PAI and PBO of the correspondiong Screens.
if you have decided to go by your first method then try the below code.
a) if it is normal UI elements like text box etc
LOOP AT SCREEN.
IF <var> = ' value '.
screen-invisible = '0'.
MODIFY SCREEN.
endif
ENDLOOP.
Here <var> refers to the screen field name and value refers to its value.
b) To hide columns in a Table control.
DATA cols LIKE LINE OF tc-cols.
LOOP AT tc-cols INTO cols.
IF cols-screen-group1 = 'G1'.
cols-invisible = 'X'. "HIDE THIS COLUMN
MODIFY tc-cols
FROM cols
TRANSPORTING invisible.
ENDIF.
CLEAR cols.
ENDLOOP.
PS: here TC refers to the name of the table control.
Lemme know if you face any problems.
Cheers,

Where did the Partitions and SubPartitions go?
I created a table with partition Range (Transaction_Date, Retention_Period) and hash (Record_Id) subpartition template (for 32 subpartitions)
Then I add more partitions and while the loop is going on I can get counts of partitions and subpartitions. The job finished and my log table shows about 1800 partitions added and there should be 32 subpartitions for each of the partitions. However, user_tab_partitions shows zero records for the table, and user_tab_subpartitions also show zero record. After a few minutes the partitions show up but no subpartitions. The indexes on the table have also disappeared (one local and one global)
Any explanation for this behaviour?
Working on Exadata 11.2.0.3
Querying
USER_TABLES
USER_TAB_PARTITIONS
USER_TAB_SUBPARTITIONS
USER_INDEXES>
Step 1. Create Table xyz (c1 date, c2 integer c3 integer, etc)
partition by range (c1,c2)
subpartition template (s01, s02... s32)
create index i1 on xyz (c1,c2,c3) local;
Then, since I want to create about 1800 partitions I have a procedure that has a "loop around" ALTER TABLE add Partition .. until all the partitions are created. This is the "Job" which while running I query USER_TAB_PARTITIONS and USER_TAB_SUBPARTITIONS to see how things are progressing. And Yes ALTER Table has no progressing to verify.
So al the partitions get created. No errors from the procedure to go through creating all the partitions. So I would expect that at the end I should get to see all the new partitions for the Table. Instead I get "no records" from USER_TAB_PARTITIONS and USER_TAB_SUBPARTITIONS.
I am also aware that "ALTER TABLE ADD PARTITION .." cannot make indexes go away. However, if the query on USER_INDEXES returns nothing, what happend to the Index created before the partitions were added?
I am not using DBMS_REDEFINITION. The only procedure is to add partitions one at a time for each date for 3 years. If you have a better way than a procedure please advise accordingly.

In order to help you the first step is to understand what problem you are dealing with. Then comes trying to determine what options are available for addressing the problem. There are too many times , and yours may, or may not, be another one, where people seem to have settled on a solution before they have really identified the problem.
Anytime someone mentions the use of dynamic SQL it raises a red flag. And when that use is for DDL, rather than DMl, it raises a REALLY BIG red flag.
Schema objects need to be managed properly and the DDL that creates them needs to be properly written and kept in some sort of version control.
Scripts and procedures that use dynamic SQL are more properly used to create DDL, not to execute it. That is, rather than use a procedure to dynamically create or alter a table you would use the procedure to dynamically create a DDL script that would create or alter the table.
Let's assume that you know for certain that your table really needs to have 1800 partitions, be subpartitioned the way you say and have partition and subpartitions names that you assign. Well, that would be a pain to hand-write 1800 partition definitions.
So you would create a procedure that would produce a CREATE TABLE script that had the proper clauses and syntax to specify those 1800 partitions. Your 'loop' would not EXECUTE an ALTER TABLE for each partition but would create the partition specification and modify the partition boundaries for each iteration through the loop. Sort of like
for i from 1 to 365 loop
add partition spec for startDate + i
end loop;The number of iterations would be a parameter and you would start with 2 or 3. Always test with the smallest code that will produce the correct results. If the code works for 3 days it will work for any larger reasonable number.
Then you would save that script in your version control system and run it to create the table. There would be nothing to monitor since there is just one script and when it is done it is done.
That would be a proper use of dynamic sql: to produce DDL, not to execute it.
Back to your issue. If I were your manager then based on what you posted I would expect you to already have
1. a requirements document that stated the problem (e.g. performance, data management) that was being addressed
2. test results that showed that your proposed solution (a table partitioned the way you posted) solves the problem
The requirements doc would have detail about what the performance/management issues are and what impact they are having
You also need to document what the possible solutions are, the relative merits of each solution and the factors you considered when ranking the solutions. That is, why is your particular partitioning scheme the best solution for the problem.
You should have test results that show the execution plans and performance you achieved by using a test version of your proposed table and indexes.
Until you have 'proven' that your solution will work as you expect I wouldn't recommend implementing the full-blown version of it.
1. Create a table MANUALLY that has 2 or three days worth of partitions.
2. Load those partitions with a representative amount of data
3. Execute test queries to query data from one of those partitions
4. Execute the same test queries against your current table
5. Capture the execution plans (the actual ones) for those queries. Verify that you are getting the performance improvements that you expected.
Once ALL of that prep work is done and you have concluded that your table/index design is correct then go back to work on writing a script/procedure that will produce (not execute) DDL to produce the main table and partitioning you designed.
Just an aside on what you posted. The indexes should be created AFTER the table and its partitions are created. If you are creating your local index first, as you post suggests, you are forcing Oracle to revamp it 1800 times when each partition is added. Just create the index after the table.
p.s. the number of posts anyone has is irrevelant. The only thing that matters is whether the advice or suggestions they provide is helpful. And the helpfullness of those is limited to, and based on, ONLY the information a poster provides. For exampe, your proposed partitioning scheme might be perfectly appropriate for your use case or it could be totally inappropriate. We have no way of knowing without knowing WHY you chose that scheme.
But I haven't seen one like that so it makes me suspicious that you really need to get that complicated. -
Create dinamic nodes and attributes
Hi Forum!
I have created a WDA with 2 views. On the START_VIEW, the user can input details from an installation. I want to display an error on the START_VIEW when a condition is false.
How I can create a node with an attribute dinamically to display this error if the message Text View is not defined on the view?
Could you give me a any sample of code, please?
Thank you very mucha and regards,
Manuel.Hi Manuel,
Pleaes try this out. This is how to create an attribute dynamically.
DATA: attribute TYPE wdr_context_attribute_info.
DATA: main_node TYPE REF TO if_wd_context_node_info.
"get main node
main_node = wd_context->get_node_info( ).
"set name for this attribute
attribute-name = 'SOME_NAME_4_ATTR'.
"set data type for this attribute
attribute-type_name = 'SOME_DATA_TYPE'.
"add attribute into context node
main_node->add_attribute( attribute_info = attribute ).
Thanks.

Change report attributes dynamically?
Can we change the report attributes dynamically? For example, I want to dynamically set some columns to be showed or not. I plan to use a radiogroup, when I choose "Partial View", the report only show some columns; when I choose "Full View", the application changes the column attributes from "hidden" to "shown".
Anyone knows how to do that in APEX 3.0? Thanks a lot.I have a radiogroup, which has two values, 1 for "Partial View" and 2 for "Full View".
I set the "condition type" to be "Value of Item in Expression 1 = Expression 2", "Expression 1" to be ":P400_RADIO" and "Expression 2" to be "2".
Anything wrong here?
Thanks a lot for your quick reply.
