Logical and primary db

Hi
Can you please tell me how to find the primary database name from standby database ?

If you mean to find Which One Primary Database Or Standby Use
SQL > select database_role from v$database;
DATABASE_ROLE
PRIMARYOn Standby
SQL > select database_role from v$database;
DATABASE_ROLE
PHYSICAL STANDBYIf you want to know instance name for database
show parameter name
select name from v$database ;

Noob needs help with Logic and Motu live setup.

Hello everyone,
I'm a noob / semi noob who could use some help with a live setup using 2 MOTU 896HD's and Logic on a Mac.
Here's the scenario:
I teach an outdoor marching percussion section (a drumline and a front ensemble of marimbas and vibes). We have an amazing setup of live sound to amplify and enhance the mallet percussion. There is a yamaha PA system with 2 subs and 2 mains which are routed through a rack unit that processes the overall PA balance. I'm pretty sure that the unit is supposed to avoid feedback and do an overall cross-over EQ of the sound. Other then that unit, we have 2 motu896hd units which are routed via fire-wire. I also have a coax cable routing the output of the secondary box to the input of the primary box (digital i/o which converts to ADAT in (i think?)..?
Here's the confusion:
There are more then 8 inputs being used from the ensemble itself, so I need the 16 available inputs to be available in Logic. I was lead to believe that the 2nd motu unit would have to be sent digitally to the 1st motu unit via coax digital i/o. Once in Logic, however, I cannot find the signal or any input at all past the 8th input (of the 1st unit).
Here's the goal:
All of my performers and inputs routed via firewire into a Mac Mini running OSX and Logic pro.
I want to be able to use MainStage and run different patches of effects / virt. instruments for a midi controller keyboard / etc.
I want to be able to EQ and balance the ensemble via Logic.
Here's another question:
How much latency will I be dealing with? Would a mac mini with 4gb of ram be able to handle this load? With percussion, I obviously want the sound as latency free as possible. I also, however, want the flexibility of sound enhancement / modification that comes with Logic and the motu896hd units.
Any help would be REALLY appreciated. I need the routing assistance along with some direction as to whether or not this will work for this type of application. I'm pretty certain it does, as I have spoken with some other teachers in similar venues and they have been doing similar things using mac mini's / logic / mainstage / etc.
Thanks in advance,
Chris

You'll definitely want to read the manual to make sure the 896HDs are connected together properly. ADAT is a little tricky, it's not just a matter of cabling them together. Go to motunation.com if you need more guidance on connecting multiple devices. Beyond that initial hookup, here are a couple of quick suggestions:
1. Open CueMix and see if both devices are reported there. If not, your connections aren't correct. Be sure to select 44.1kHz as your sample rate, otherwise you are reducing the number of additional channels. For instance at 88.2kHz you would get half the additional channels via ADAT.
2. You may need to create an aggregate device for the MacBook to recognize more than the first 896HD. Lots of help on this forum for how to do that. Again, first make sure you have the 896HDs connected together properly.
3. As for latency with Mainstage on the Mini, no way to know until you try it. Generally MOTU is fantastic for low latency work but Mainstage is a question mark for a lot of users right now. If the Mini can't cut the mustard, you have a great excuse to upgrade to a MacBook Pro.

Logical and Physical Standby on same Node

Is it possible to have a logical and physical standby database for a primary database on the same node (i.e. primary on NodeA, logical and physical database of primary on NodeB)?
Will there be any conflicts with data guard broker with this configuration or any problems I may encounter?

From a technical point of view this is possible. Your standby node should be powerful enough to handle 2 instances. For even higher availability 3 dedicated nodes would be better. When Node B is down, both physical and logical standby are also down.

Logical and physical rowid datatypes

can i know how logical and physical row id be helpful to a developer.
if i am not wrong than physical row id remain constant and logical is on IOT and can change but what is its use how can i use this concept and where can i apply it ???

if i am not wrong than physical row id remain constant and logical is on IOT and can change but what is its use how can i use this concept and where can i apply it ???A row's logical rowid does not change as long as the primary key value does not change. This is less stable than the physical rowid, which stays immutable through all updates to the row.

HT201356 Why can't I change my "Apple ID and Primary Email Address" to an email address using an Apple domain?

I am trying to use an Apple EMail address as my primary email address and I am unable to change it. I previously had another "nonapple" address identified as my Apple ID and Primary Email address. Now I apparantly can only change it to another "non Apple" related email address. It seems stupid to have to go to Google and use thier email address to make a change.
What gives.

Thanks Roger! I understand that it is an Apple ID already that makes sense. That "non Apple " address however, is compromised and I do not wish to use it anymore and will be shutting it down. I find it strange that I must only identify a "Non Apple" address as my "primary email address". I have an alias address on the account and I can sign in using it as my Apple ID. i don't see the Logic in forcing someone to use another email provider as your primary mail service. (I know I can set up alias's and use them under an Apple domain, but the primary email will still be there and I understand used for any account communications from Apple.) Any further comments on this situations?

Logical AND in MDX Reporting Services Parameter

Hi, I would like to implement logical AND on a cube parameter. I have seen examples of hard-coded logical AND in MDX.
(http://salvoz.com/blog/2013/12/24/mdx-implementing-logical-and-on-members-of-the-same-hierarchy/)
But I'm not sure how to apply this to a parameter's MDX dataset.
Here is an example of the automatically generated MDX which uses logical OR:
This is the drop down parameter:
WITH MEMBER [Measures].[ParameterCaption] AS [Department].[Department].CURRENTMEMBER.MEMBER_CAPTION MEMBER
[Measures].[ParameterValue] AS
[Department].[Department].CURRENTMEMBER.UNIQUENAME MEMBER [Measures].[ParameterLevel] AS
[Department].[Department].CURRENTMEMBER.LEVEL.ORDINAL
SELECT {[Measures].[ParameterCaption], [Measures].[ParameterValue],
[Measures].[ParameterLevel]} ON COLUMNS
, [Department].[Department].ALLMEMBERS ON ROWS
FROM [MyCube]
And the demo report dataset is:
SELECT NON EMPTY { [Measures].[CompanyTbl Count] } ON COLUMNS,
NON EMPTY { ([Product Level No].[Product Level No].[Product Level No].ALLMEMBERS ) }
DIMENSION PROPERTIES MEMBER_CAPTION, MEMBER_UNIQUE_NAME ON ROWS FROM
( SELECT ( STRTOSET(@DepartmentDepartment, CONSTRAINED) )
ON COLUMNS FROM [MyCube]) WHERE
( IIF( STRTOSET(@DepartmentDepartment, CONSTRAINED).Count = 1,
STRTOSET(@DepartmentDepartment, CONSTRAINED), [Department].[Department].currentmember ) )
CELL PROPERTIES VALUE,
BACK_COLOR, FORE_COLOR, FORMATTED_VALUE, FORMAT_STRING,
FONT_NAME, FONT_SIZE, FONT_FLAGS

Hi,
I can see there just one parameter @Department@Department in your script. But if you had two parameters that should return resultset affected by two parameters. You can do it as either select from subselect from subselect.
Example 1
SELECT
{x} ON COLUMNS,
{ROWS_SET} ON ROWS
FROM
(SELECT StrToSet(@Param1) ON COLUMNS FROM
(SELECT StrToSet(@Param2) ON COLUMNS FROM
[CUBE_NAME]
Or crossjoin between 2 parameters
SELECT
{x} ON COLUMNS,
{ROWS_SET} ON ROWS
FROM
(SELECT StrToSet(@Param1)*StrToSet(@Param2) ON COLUMNS FROM
[CUBE_NAME]

What is a Logical and Physical file path in sap?

what is a Logical and Physical file path in sap?

Hi,
Physical file is what you see from the OS level.
Logical file is what ABAP code can call certain functions to read/write.
Transaction FILE would link them together. Typically the logical path ends with "<FILENAME>", and the logical file refers to the logical path.
To extract the physical path from the logical path name
DATA: lf_mandt TYPE sy-mandt,
        lf_opsys TYPE sy-opsys.
lf_mandt = sy-mandt.
lf_opsys = sy-opsys.
To extract the physical path from the logical path name
CALL FUNCTION 'FILE_GET_NAME'
    EXPORTING
      client           = lf_mandt
      logical_filename = p_unix
      operating_system = lf_opsys
    IMPORTING
      file_name        = gwa_input
    EXCEPTIONS
      file_not_found   = 1
      OTHERS           = 2.
IF sy-subrc EQ 0.
Concatenating the physical path and the input unix file name
    CONCATENATE gwa_input p_file INTO gf_file .
ENDIF.

Logical AND not working in the forum search box

Logical AND of search terms does not seem to be working in the MSDN forum search box. Example: I go to the Project Customization and Program forum and type the word
subproject
in the search box. I get a lot of hits. So now I try to reduce the number of hits by typing
subproject AND read
Surprisingly, I now get MORE hits than before. The same thing happens if I enter
subproject & read
Do the MSDN forums not support the standard logical AND combinations of search terms? If they do support these combinations, what is the syntax?

Logical and physical clear in ASO

Hi There,
I found one statement for Logical and physical clear in essbase dbag
The process for logically clearing data completes in a length of time that is proportional to
the size of the data being cleared.
The process for physically clearing data completes in a length of time proportional to the
size of the input data, not to the size of the data being cleared
What does size of the input data actually means? How it is different from data being cleared.
Thanks.

What is interesting with these statements is based on them, you would think a logical clear would be slower than a physical clear. In reality, it is vastly faster. I took a 30 minute physical clear down to about 40 seconds with a logical clear. Logical clers create offsetting entries from the main cube in a slice to produce a result whila a physical clear deletes the actual data. The one thing about logical clears is rather than have #missing for cleared intersections you get zeros

Logical AND in Java Regular Expressions

I'm trying to implement logical AND using Java Regular Expressions.
I couldn't figure out how to do it after reading Java docs and textbooks. I can do something like "abc.*def", which means that I'm looking for strings which have "abc", then anything, then "def", but it is not "pure" logical AND - I will not find "def.*abc" this way.
Any ideas, how to do it ?
Baken

First off, looks like you're really talking about an "OR", not an "AND" - you want it to match abc.*def OR def.*abc right? If you tried to match abc.*def AND def.*abc nothing would ever match that, as no string can begin with both "abc" and "def", just like no numeric value can be both 2 and 5.
Anyway, maybe regex isn't the right tool for this job. Can you not simply programmatically match it yourself using String methods? You want it to match if the string "starts with" abc and "ends with" def, or vice-versa. Just write some simple code.

Difference between primary key and primary index

Dear All,
Hi... .Could you pls tell me the difference between primary key and primary index.
Thanks...

Hi,
Primary Key : It is one which makes an entry of the field unique.No two distinct rows in a table can have the same value (or combination of values) in those columns.
Eg: first entry is 111, if you again enter value 111 , it doesnot allow 111 again. similarly for the strings or characters or numc etc. Remember that for char or numc or string 'NAME' is not equal to 'name'.
Primary Index: this is related to the performance .A database index is a data structure that improves the speed of operations in a table. Indices can be created using one or more columns, providing the basis for both rapid random lookups and efficient ordering of access to records. The disk space required to store the index is typically less than the storage of the table (since indices usually contain only the key-fields according to which the table is to be arranged, and excludes all the other details in the table), yielding the possibility to store indices into memory from tables that would not fit into it. In a relational database an index is a copy of part of a table. Some databases extend the power of indexing by allowing indices to be created on functions or expressions. For example, an index could be created on upper(last_name), which would only store the uppercase versions of the last_name field in the index.
In a database , we may have a large number of records. At the time of retrieving data from the database based on a condition , it is a burden to the db server. so whenever we create a primary key , a primary index is automatically created by the system.
If you want to maintain indices on other fields which are frequently used in where condition then you can create secondary indices.

BEx Formula Use of 'Logical And' and Calculation for Gross Margin

HI Bex gurus.
Having an odd time with what should be a simple formula to handle the display of gross margin (GM). The goal here is to display GM% properly and the requirement is as follows
If GM <= 0 then 0.0
Else
If GM > 0 and Sell > 0 then ( ( sell - cost /sell ) * 100 )
Else
If GM >0 and Sell = 0 then 100
I am familiar with bex formulas and have referenced the help docs on booleans here -
Boolean Operators - SAP Business Explorer - SAP Library
But what is odd is that if I use a calculation or a CFK in the IF, THEN with a LOGICAL AND, the formula does not report correctly
If I put in a static value, like 77, the expected logic is followed. I have tried making sure have extra parentheses and changing the order of the statement, to no avail! I could use some extra brains on this puzzling matter, so you help is greatly appreciated and will award points!
Thanks
lee lewis
Here are the formulas in text and below screen shots. Wish could copy and past formulas to and from editor!
GM%77
( ( ( 'Order GM' >0 ) AND ( Order Sell > 0 ) ) == 1) * 77 + ( ( ( 'Order GM'> 0 ) AND ( Order Sell == 0 ) ) == 1) * 100 + ('Order GM' <= 0) *0.0
GM%
( ( ( 'Order GM' >0 ) AND ( Order Sell > 0 ) ) == 1) * 'REF GM%' + ( ( ( 'Order GM' > 0 ) AND ( Order Sell == 0 ) ) == 1) * 100 + ('Order GM' <= 0) *0.0
'REF GM%
(order sell - order cost /order sell ) * 100 )
GM%77
GM%

Shouldn't you change on of the brackets in your REF GM% ?
'REF GM%
(order sell - order cost /order sell ) * 100 )
I would put that as
'REF GM%
(order sell - order cost) /order sell * 100 )
Not sure what you mean with those red arrows... but in both cases you would be dividing by 0 (order sell = 0).

I created an Apple ID for my daughter with her own gmail address, but I want her Apple ID and primary email address to be an iCloud email address. How can I do this? I can't set up an icould email address for her without first creating an Apple ID?

I have created an Apple ID for my daughter with her own gmail address as the primary email address, but I want her Apple ID and primary email address to be an iCloud email address. How can I do this? I can't set up an icould email address for her without first creating an Apple ID right?
I'm not good with computers so please explain in simple way...:)
I also wonder what the best way is to set up accounts for children in a family. I dont want them to be able to purchase apps etc through the parents accounts, also some things we like to share as a family and others we don't want to share. Is there any good. clear, simple explanation from Apple Support about these issues? Or best to go to Apple store and go to genius bar or one to one advise?
thanks

You can set up an iCloud account which makes the iCloud email address you choose the Apple ID and thus the login for it:
https://discussions.apple.com/message/22283348#22283348
though I have to say I think it's more sensible if the ID is another address, both for security reasons (so people don't know what the login is) and as a contact address from Apple if the account were to stop working and they needed to contact you. So personally I would to to System Preferences, enter the GMail address which is an ID, and then choose a nerw @icloud.com address.
If she has her own iCloud account she will need either her own computer or her own user account on your Mac to be able to make use of it. You should note that under Apple's terms of use Apple IDs are only available to children of 13 and over.
As to purchasing apps, this is nothing to do with iCloud: it's iTunes, and the login can be different. So you can all sign into the same iTunes account but have different iCloud accounts. Or she can have her own iTunes account if she is of suitable age (credit card needed for purchasing apps).
If you have other children you should be aware that any one Mac or device can create only three iCloud accounts - this is tied to the serial number, not the user account, and once reached cannot be bypassed. You can of course sign into an iCloud account created on another device.

I changed my appleID and primary email and now I can not access anything. iphone shows my old appleID and I can't log in with my old password but I can not log out and log in with new ID. How do I get iphone to work with my updated ID?

My old nternet account was cancelled and with it my emails. I updated my apple id and password in all my devices (ipad, iphone, imac, except for my moms iphone. I am trying to log out from my old account and set her up with her own apple ID and iCloud etc but it does not let me log out. I have a notebook with all my passwords in it so I know for a fact the password for the old ID/ email is correct yet a window keeps popping up that it is incorrect. I have spent hours reading and trying to fix it myself and nothing is working, same window keeps popping up. Any ideas on what to do? I have an iphone 4S, all software up to date and I made sure my moms phone is also updated. Thank you, any help is greatly appreciated.

Hi ccharat,
Welcome to the Apple Support Communities! It sounds like you did a good job editing your Apple ID and primary email address, but you didn’t sign out of iCloud on your iOS device before hand. What you may need to do in this situation is go back to the Apple ID website and edit your Apple ID and primary email address back to the email address that is signed in with iCloud (there is no need to verify the account after editing it back to the old account, just changing it back is enough). Once your Apple ID is back to the original account, delete the iCloud account from the iOS device and be sure to keep all info on the device when prompted. After you delete the iCloud account, go back to the website and edit your Apple ID and primary email address back to the new address. Once it is back to the account you would like, you can sign into the iCloud on the iOS device with that new account and merge all of the data when prompted. Please use the following article as a reference.
iOS 7: If you're asked for the password to your previous Apple ID when signing out of iCloud
http://support.apple.com/kb/ts5223
Change your Apple ID temporarily
If signing out and back in to iMessage or FaceTime didn't help, try these steps:
Change your Apple ID to the Apple ID you used previously. You shouldn't need to verify the email address.
Go to Settings > iCloud. Complete these steps only if the Find My [Device] setting is turned on:
Scroll down and tap Delete Account, then tap Delete to confirm.
Tap “Keep on My [Device]” or “Delete from My [Device].” In either case, your data remains in iCloud and will be updated on your device when you sign in to iCloud again.
Enter the password for your previous Apple ID.
Change your Apple ID to the new email address that you want to use. You'll need to verify the email address.
Return to Settings > iCloud and sign in with your new Apple ID.
I hope this helps,
-Joe
