Some issues related to the Oracle OLAP features
Hello!I have a few questions for which I'm not sure that it supports Oracle OLAP:
1. several hierarchies of time?
2 measure groups?
3. visible values?
Thank you!
Best regards, Simon
(1) oracle OLAP supports multiple hierarchies on any dimension, including the dimensions of time. But note this means something different from multiple hierarchies in Microsoft Analysis services.
(2) oracle OLAP has multi-cube architecture, so you can easily combine several cubic measures in a single query. This allows to create the equivalent of a measure group. You can do this either by creating a new cube with calculated measures that point the cubes from the base, or at the SQL level by joining the views of cube. There are advantages to both approaches.
(3) oracle OLAP has no native support for the visible values. To get the visible values, you need to run the part of aggregation in SQL.

Some issues related to the digital signature on an interactive form
I just finished a contract of interactive advertising with a 128-bit encryption allowing recipients to submit CC of information securely to our publishing company. Even if the form in the upper fields allow to type the name of an authorized person, the signature on the bottom line is having problems because so that everyone to sign, they need a digital signature.
(1) is it necessary? If so, is it possible to automate it for customers, so they do not have to go through the process of creating one?
(2) how to create a digital signature for my partner and have the form SUBMIT button channel back to his address of e-mail instead of mine (which it does because of another interactive form, that I created in which I was the person for returns)? I couldn't find anything in the 'properties' of the OK button that allowed me to enter an e-mail address.
I thank very you much for your help here. It's time-sensitive, because we need get the package ASAP.
1 if you need a digital signature, then set up a digital ID is required to sign a digital signature field. So the question is really more fundamental: you need people to sign the form with a digital signature? If you say yes, what are the reasons?
2. If you use the distribution process in Acrobat so thatt you can collect form data in an answer file, you should distribute the form using the other person with Acrobat installed on machine.
If you don't want to do this and you want to only collect the documents returned without putting the data in an answer file, you can configure your own submit button using any email address you want and that you do not use the distribution process. You must activate the document reader and then send or otherwise get for users. How to configure the Send button depends on how you want it to run exactly and which version of Acrobat you are using. More information can be found here: http://acrobatusers.com/tutorials/form-submit-e-mail-demystified
If you want to continue to go through the process of distribution and want to change the email address it uses, you can change it to: Edit > references > identity > Email address
You will then have to redistribute the form with a copy of the form as it existed before your first distribution. The answer file will be on your machine.

Exerted on the free Oracle OLAP features with Oracle 11 g EE?
Hello
Exerted on the free Oracle OLAP features with Oracle 11 g EE?
Information found on the Internet:
-Oracle Corporation markets the Oracle database OLAP Option optional additional costs to complete the "Enterprise Edition" of its database.
-Oracle OLAP database is it preinstalled with the rest of the Oracle database ERA. You just need her license for use on the Machine of DB when you choose to use it.
-Oracle OLAP is a multidimensional analytical engine world class integrated into the Oracle 11 g database.
Please confirm if I can try some OLAP features in my office where I have Oracle 11 g what EE installed as asked me to do an initial POC?
Kind regards
SudhirHello
I think that the OLAP license is covered by the OTN Developer License - http://www.oracle.com/technetwork/testcontent/standard-license-088383.html
You should contact your representative local Oracle sales if you are still not sure

question related to the Oracle documentation
Hello
I have a small doubt. Y at - there no standard doc Oracle who discuss about the standard RDBMS concepts like standardization, codd rules etc.
See you soon,.
Suri ;-)
In my humble OPINION, include the best way to understand the concepts of data modeling. I don't know that all of the Oracle documentation covers this area to the extent, but I found some books that give examples of explanations. These are old classic books, but the theory has not changed. The first two are good for designing OLTP and the last of them is good for data warehouses. OLTP books are CASE * method entity relationship modeling by Richard Barker and The Data Model Resource Book by Len Silverston. Both give a lot of examples with good explanations. The third is the Data Warehouse Toolkit by Ralph Kimball. Not everyone will agree with the logic, because there is room for interpretation when it comes to design concepts.

Issues related to the parental control EA6900
I have my setup of parental control to block access from 22:00 to 09:00 however, it does not automatically access when the time changes to time 'unlocked '. Curiously, it still shows the message 'parental control block. I have to disable the parental control to allow access to devices after 9:00 and then it must reactivate at 22:00 to block access again.
I've also updated the latest firmware (1.1.42.161129). It does not seem to be 2 versions (V1.0 or V1.1), however, these two seem to be the same file. I used the correct version for my router (V1.0).
I want to stay with what you have for now and look to see if it works on some devices. Check that the clock on the router is configured correctly. See also if certain sites are blocked and others not. I think there's a bug where some sites using https:// is not to be blocked but http:// did. It worked correctly before the upgrade? Remember you of what was the old version? The cancellation is made by the interface of the router and there is a button to restore but still, if restore you an unwanted version which isn't good either. Better do small things first.

Basic functions and issues related to the Internet after virus removal
I hope someone can help with my daughter's laptop. I think this is the right forum.
Back in March she got a rogue virus on his laptop computer. It has been removed successfully, but the programs on his personal user account have still some problems. She tries to open any program by double-clicking its icon, a screen will appear asking you to choose a program from a list to open it with. If instead, she clicks on the icon of the program and chooses to start, it opens fine (but is very painful to have to do so every time). In addition, some basic on this user account functions do not work (it does not receive some pop-up windows to the top when it should, the scroll bar on its mouse pad no longer works, programs configured to start at startup must be started manually, etc.). Finally, after being and deletion of another rogue virus a few weeks ago, the internet on his personal user account stopped working, only display a "Cannot display the Web page" page even if network connections show that it is connected to the internet. NOTE: None of these problems exist on the administrator account or if she is invited to log on as an administrator.
A gifted friend computer has helped to ensure that the computer is free of any virus or malware but was not able to understand how to fix this user account. It was suggested to delete this account and create a new user, but she doesn't want to have to do that, if possible, since she spent a lot of time customizing.
The laptop is a HP Touchsmart PC with Windows Vista Edition Home Premium (x 64), AMD Turion X 2 Dual - Core Mobile RM-75.
Thanks in advance!
Ok.
Here's a little advice for her on the copy of files on new accounts:

Difficulty of a corrupted user profile
After creating the profile, you can copy the files from the existing profile. You must have at least three user accounts on the computer to perform these operations, including the new account that you created.

issues related to the parameter in the procedure
Hi all
I have a procedure which the code is given below:
create or replace PROCEDURE seods01.get_cert_tx_lot_tmp (acct_alt_id_in in VARCHAR2
, acct_alt_id_cntx_cde_in IN VARCHAR2 default 'COLA account number.
, ibd_id_in IN INTEGER
qry_rslt_out to sys_refcursor)
IS
BEGIN
OPEN FOR Qry_rslt_out
SELECT L.tx_lot_seq_nbr
L.hld_prd_dte
L.orig_purc_dte
L.tx_lot_amt
L.updt_tx_lot_amt
L.tran_desc_txt
OF v_acct_alt_id A
v_cd_tx_lot L
WHERE A.acct_alt_id = acct_alt_id_in
AND A.acct_alt_id_cntx_cde = acct_alt_id_cntx_cde_in
AND A.ibd_id = ibd_id_in
AND L.eods_acct_id = A.eods_acct_id;
EXCEPTION
WHILE OTHERS THEN
dbms_output.put_line(SQLCODE||) SQLERRM);
END get_cert_tx_lot_tmp;
now when I run the SP in the following way it works fine:
VAR C1 REFCURSOR EXECUTE SEODS01.get_cert_tx_lot_tmp ('004000000000000093108026740', 'Number of COLA account', '1',: C1); PRINT C1
When I try to ignore this value by default setting, then it is throwing ' wrong number or types of arguments "error
VAR C1 REFCURSOR EXECUTE SEODS01.get_cert_tx_lot_tmp ('004000000000000093108026740 ', ' 1',: C1); PRINT C1
and when I tried to put this as null or "then it gives me no results. only way through which I can produce results of this procedure without giving the default parameter is the name of the column with the value of the parameter as follows:
VAR C1 REFCURSOR RUN SEODS01.get_cert_tx_lot_tmp (acct_alt_id_in = > '004000000000000093108026740', ibd_id_in = > '1', qry_rslt_out = >: C1); PRINT C1
but the condition is that we do not want our consumers to put names of columns when they do not pass the default value setting, I hope that there should be a way to do it. Could someone help me please on this issue.
Hello
If you want to use positional notation, then you can only omit parameters by default when they are at the end of the parameter list. In your case, this would mean
(acct_alt_id_in in VARCHAR2
ibd_id_in in FULL
qry_rslt_out ON sys_refcursor
acct_alt_id_cntx_cde_in IN VARCHAR2 default 'COLA account number')
Or you can put the procedure in a package and overload
PROCEDURE seods01.get_cert_tx_lot_tmp
(acct_alt_id_in in VARCHAR2
acct_alt_id_cntx_cde_in IN VARCHAR2
ibd_id_in in FULL
qry_rslt_out to sys_refcursor)
PROCEDURE seods01.get_cert_tx_lot_tmp
(acct_alt_id_in in VARCHAR2
ibd_id_in in FULL
qry_rslt_out to sys_refcursor)
In the procedure without the acct_alt_id_cntx_cde_in parameter, you can call the other version and provide the default value.

Issues related to the suppression in ASM and Archivelog place
All,
Please find my contact information environment
Oracle 10.2.0.4.0
Linux - RHEL5
2 node RAC environment
Two days back, I created 2 test environment for node. It is in archivelog mode, but not configured to the RMAN catalog database.
Within two days, test team had done a lot of activities as the addition of data, stress tests etc and FRA was filled by more than 85%.
Now, asked me to register the database with the RMAN catalog and they are very well to remove the previous archivelogs.
Once the database is registered with the RMAN catalog, I have to take fresh full backup and the need to retain the archivelogs after taking backup.
Now, since I need to remove the archivelogs, which is not necessary, I manually went ASMCMD mode and remove the archivelogs several, but when I request
SQL > select * from v$ flash_recovery_area_usage; I don't see no decrease in percentage as and when I delete files in mode ASMCMD.
Please tell me what mistake I make. Is the best way to remove the ASMCMD mode? Given that my database is not configured for catalog RMAN from now on, I am not able to use RMAN to delete the archivelogs.
Waiting for your valuable suggestionsAfter you remove the archivelogs using ASMCMD, did you run
CROSSCHECK ARCHIVELOG ALL; DELETE EXPIRED ARCHIVELOG ALL;in RMAN?
Those who would update the repository.
Then check V$ FLASH_RECOVERY_AREA_USAGE

I have a bunch of folders and subfolders, I created for various projects, but I don't always want to see them. (that is, I want to "collapse", while most of the time - I just see the Inbox, sent, spam and trash folders.)
The only option I see is the equivalent of a power switch - that is to say, file view/page/component layout, or no record.
If you uncheck the folders pane, you lose the Inbox, sent, spam and trash folders.
If you check the option part of file, regain you your visibility of the Inbox, sent, junk mail and folders trash... but you also see the bunch of files again.
Is there an option in-between - where I can see (again) the Inbox, sent, junk, and trash folders - but only see a collapse (as in 1 folder that says something like "folders") - without having to create such a file and paste the slew of my other folders in the folder manually created?
The only suggestion that I would have to choose the name of the account, not the Inbox but the name of the main account.
Right-click on the account name, and then select new folder.
Name the project or something that makes sense to you.
Now right-click in project and select new subfolder.
The name of the subfolder.
Repeat if necessary.
There will be a pointer next to the projects folder where you can expand or collapse the tree of project files.
This will only add an extra folder, projects, when the project tree is reduced.
