How to convert cluster to waveform?

I'm having trouble building a waveform properly. I have a relativeX, an Xincrement, and a 1D array of data (what is returned from a 5114 scope). But the 'build waveform' function wants t0 to be a timestamp. This isn't what I want....
I don't mind just using the cluster for showing it on a waveform graph because it works and it's not a problem. However, there are a lot of waveform functions for writing waveforms to files that I would like to take advantage of....how can I do this?
thanks,
-Z

I think I am with you and the answer is probably not. You can work with both datatypes but if you want to use waveform datatype then there is a little more work to get the graphs looking the same with a negative x0
Let me know you labview version and I will post the above vi for you to study.

Try using Read from Spreadsheet File.vi. It will convert a tab-delimited text file into an array of numbers in one step.

OK. Can open them now.
From a programmatic perspective and usability perspective, what do you see as the main advantage of this method as opposed to using the Flatten To String and Unflatten From String functions without going through an intermediate variant? Or, perhaps, the Flatten to XML/Unflatten from XML functions. In other words, what are the pros and cons of your method as opposed to this method:
One clear advantage of your method clearly is that you do not need to wire in the data type, as you need to do with the Unflatten From String function. Were you addressing other concerns?

Convert a rpm waveform to digital/analog tach signal. Sound & Vibration

Hello,
my question is: How to convert a rpm waveform to
digital/analog tach signal for use with SV application?
Or is it possible to modify the SV - VIs for the use of
a rpm waveform or a speed signal?
Thanks a lot for coming answers.
Thomas Nuding

Typically an RPM waveform is the analog view of a tachometer, such as a proximity probe over a key or keyway, or an index pulse from an electric motor. In most rotor dynamics applications, the phase of the tachometer waveform is compared to the phase of other waveforms, such as vibration, to determine the angular position of the shaft when the other waveform occurs.
The sound and vibration tools have a function for calculating RPM from an analog tachometer waveform. The order analysis toolset go further to add a counter as an tachometer input. The OAT tools also allow for selection of rising edge or falling edge and voltage level for the "trigger". A time instance is recorded when the edge occurs. This time instance is used for phase measurements and for resampling the other waveforms into the angular domain, ie. 360 measurements per revolution.

How to convert Internal Table to Cluster Table ?

How to convert Internal Table to Cluster Table ?

Use :
EXPORT itab TO DATABASE dbtab(ar) ID key.
<i>EXPORT obj1 ... objn TO DATABASE dbtab(ar) ID key.
Additions:
1. ... = f (for each field you want to export)
2. ... FROM f (for each field you want to export)
3. ... CLIENT g before ID key )
4. ... USING form
5. ... FROM wa (as last addition or after dbtab(ar))
In an ABAP Objects context, a more severe syntax check is performed that in other ABAP areas. See Implicit field names not allowed with clusters and Table work areas not allowed.
Effect
Stores a data cluster in database table dbtab. The specified objects obj1 ... objn (fields, structures, or tables) are stored as a single cluster in the database table dbtab.
The specified database table dbtab must have a standard structure.
The database table dbtab is divided into various logically-related sections (ar, two-character name).
You can export a collection of data objects (a data cluster) to a part of the database using a key (field key).
You can import individual data objects from this collection using the IMPORT statement.
Notes
In classes, you must always assign explicit names to the data objects you want to export, that is, you must use either addition 1 or addition 2.
In classes, you must always specify the work area explicitly, that is, addition 5 is obligatory.
The table dbtab that appears after DATABAE must be declared under TABLES (except in addition 5).
You cannot export the header lines of internal tables. If you specify the name of an internal table with header line, the system always exports the body of the table.
You cannot export data, object, or interface references.
The data is stored in the database, and is consequently not actually stored until a database commit occurs (see LUW). Until this point, you can undo all of your changes using a database rollback (see Programming Transactions).
Example
Exporting two fields and an internal table to the database table INDX:
TABLES INDX.
TYPES: BEGIN OF ITAB3_TYPE,
          CONT(4),
       END OF ITAB3_TYPE.
DATA: INDXKEY LIKE INDX-SRTFD VALUE 'KEYVALUE',
      F1(4), F2 TYPE P,
      ITAB3 TYPE STANDARD TABLE OF ITAB3_TYPE WITH NON-UNIQUE
                 DEFAULT KEY INITIAL SIZE 2,
      WA_INDX TYPE INDX.
Fill the data fields before CLUSTR
before the actual export
INDX-AEDAT = SY-DATUM.
INDX-USERA = SY-UNAME.
Export der Daten.
EXPORT F1    FROM F1
       F2    FROM F2
       ITAB3 FROM ITAB3
       TO DATABASE INDX(ST) FROM WA_INDX ID INDXKEY.

How to convert waveform into complex number

Hi,
I need to convert the acquired voltage and current waveform through DAQ card into complex numbers in order to find the phase relationship
between the waveform.Can u tell me is there any method to convert the acquired waveform into complex number array
or is there any other method to find the phase??
please help me in this
Regards
Meenatchi

Dear Meenatchi,
I am attaching two sample VI s for the issue you are facing. Hope this helps.
The waveform in array format.vi gives you the values of the waveform obtained from your DAQ card in an array directly. You can choose this mode by selecting it from the options available on the DAQmx read vi. But if you still want to extract the array from the waveform data type please navigate to programming >> waveform >> get waveform components and extract the array component.
The phase of the complex number created.vi gives you and array of the phases. Please specify the number of iterations of the for loop that determines the size of the array.
If you need any further assistance, please feel free to contact us.

How to convert single instance10g db to 11gR2 RAC with ASM

Hi,
I need your help to decide the plan about how to convert single instance 10g database to 11gr2 rac with asm.
I can have about 6 to 8 hours of downtime to upgrade and move to rac with asm.
db size is about 1.5tb and on AIX.
here is my plan....
1) install 11gr2 rac with asm on two nodes
2) verify rac installation and clustered asm
3)install 10g oracle binaries( yes 10g )
4) shutdown production db ( machine prod )
5) make copy of production and restore on 1st node ( using shadow image , so it's quick and its file system )
6) upgrade db to 11g ( still of file system )
7) after successful upgrade, move to asm ( rman backup )
8) add another node
does it look okay ? OR is there a better approach to save time?
can someone help me ?
Thanks...

Thanks ...
So here is what I thought... suggest if something is not right...
1) install 11gr2 grid infra on node A and B with ASM
2) stop CLUSTER ON BOTH NODES.
3) shutdown prod db on 10g ( downtime starts )
4) take rman cold backup
5) restore rman backup on node A on ASM ( as if single instance 11g , no rac parameters )
6) mount and run upgrade script for 11g, then open db with 11
7) after successful upgrade, shutdown db node A
8) change all rac related parameters, spfile,undo,redo for rac environment on both nodes
9) open db in rac environment
can I do this way ?
My only question is, even though I installed rac on node A and B, in step 5 and 6 I'm using only node A as if it is single instance. Is it possible ?
if it is then I'm good to go...
Thanks for all suggestions.

How to convert a Logical Standby DB to a Primary

Hi,
I have an issue with our Data Guarded cluster (two nodes, one Primary and one Logical Standby Oracle 10i DBs running on HP-UX 11.23)
The issue is that for some reasons the Primary and the Standby are out of sync in terms of archive log sequences.
For instance the primary shows:
Date: Feb-27-2009 14:02:33
ID DESTINATION STATUS ARCHIVED_THREAD# ARCHIVED_SEQ#
1 /db05/oradata/NSMS/archive/ VALID 1 864
2 stdby VALID 1 10
3 /db05/oradata/NSMS/archive/DR/ VALID 1 11
11 /db05/oradata/NSMS/archive/DR/ VALID 1 864
Report on Redo Log Gaps between Primary and Standby.
Date : Feb-27-2009 14:02:33
LAST_SEQ_RECD LAST_SEQ_SENT
863 864
But the STANDBY shows in the alert log:
LOGMINER: Begin mining logfile: /db05/oradata/NSMS/archive/DR/arch673877647_1_304.log
Fri Feb 27 12:51:36 2009
LOGMINER: End mining logfile: /db05/oradata/NSMS/archive/DR/arch673877647_1_304.log
Fri Feb 27 12:51:36 2009
LOGMINER: Begin mining logfile: /db05/oradata/NSMS/archive/DR/arch673877647_1_305.log
Fri Feb 27 12:51:39 2009
LOGMINER: End mining logfile: /db05/oradata/NSMS/archive/DR/arch673877647_1_305.log
since the DBA_LOGSTDBY_LOG contains on the STANDBY:
$ is_db_apply_current.sh
1 300 595040838 595042886 YES
1 301 595042886 595042919 YES
1 302 595042919 595096418 CURRENT
1 303 595096418 595127201 CURRENT
1 304 595127201 595159342 CURRENT
1 305 595159342 595207457 CURRENT
At this point I don't know how to cleanup the situation on the Standby.
I tried to resync completely form primary copying all datafiles and archives but still cannot reset the archive sequence on the STANDBY, so that it keeps looking for the wrong archives.
Thanks in advance !
Mike

Hi
Problem seems different then post heading."How to convert a logical standby to primary" stepts are follow.
On primary site.
1.On primary site "alter database prepare to switchover to logical standby".
2.On standby site "alter database prepare to switchover to parimary;
3.Check "select switchover_status from v$database to both sites.
4.At primary site When status becomes to_standby then "alter database commit to switchover to logical stanedby".
5.At stndby site "alter database commit to switchover to parimary".
6.After successfully switchover at new logical standby site "alter database stard logical standby apply".
For you problem ,Can you paste following from standby site.
1.select applied_sequence#,last_sequence# V$logstdby_progress.
2.select * from V$logstdby_stats
3.select * from v$archived_log
Also from primary site,
1.select * from v$log.
hope this will help U.

How to create cluster table

Hi
this is fazil.
Please tell me any body how to create cluster table.
Thanks & Regards
Fazil
[email protected]

Hi,
1. In the initial screen of the ABAP Dictionary select object type Table, enter a table name and choose Create.
The field maintenance screen for the table is displayed. Table type Transparent table is set as default.
2. Make the necessary entries in the Short description and Delivery class fields on the Attributes tab page. Then define the fields of the table.
Proceed as when creating a transparent table. Save your entries.
3. Choose Extras ® Change table category.
A dialog box appears in which you have to select the table type Pooled table or Cluster table.
4. Choose Select.
You return to the field maintenance screen for the table. Field Pool/cluster name is displayed on the Attributes tab page in addition to the standard fields.
5. Enter the name of the table pool or table cluster to which you want to assign the pooled table or cluster table in field Pool/cluster name
Note that the total key length of a pooled table may not exceed the key length of the associated table pool. The key of a cluster table must correspond to the key of the associated table cluster.
6. Proceed as when creating a transparent table (see Creating Tables). Remember that you cannot create indexes for pooled or cluster tables.
All the attributes of the technical settings can be maintained for pooled tables and cluster tables. Before you can access these attributes, however, you must convert the table to a transparent table.

-nowarn instruct the Converter to not report warning messages
-mask indicate this package is for mask, so restrictions on
native methods are relaxed
-debug enable generation of debugging information
-nobanner suppress all standard output messages
-noverify turn off verification. Verification is default
*********************************************************May I know What is the correct command line to convert the class file and what must I do to before converting the class file?

How to convert string to 16 characters.

My external unique id is too long, more then 30 characters.
How to convert it to 30 characters using sql?

You should find another extranal system id in order to mantain uniqueness, but you could also use the name field (that supports 50 characters), but it deppends of which entity you are using.
Which is the entity? and...if the only way to insert data is by web services the you could use more than one field to verify uniqueness since you can query more than one field at the time.
Hope it helps

How to convert Web app into a channel?

To whom it may concern,
Does anyone know how to convert a Web app into a channel inside the Portal server 6.0?
I developed the web app and tried to create a provider and a channel for it, but the Portal server did not recognize the WEB-INF folder and give me errors saying that it couldn't locate the class files.
I also have a problem with URL inside my jsp page (channel).
For example, I have two jsp pages:
/etc/opt/SUNWps/desktop/default/MyCustomProvider/test1.jsp
/etc/opt/SUNWps/desktop/default/MyCustomProvider/test2.jsp
and when I try to put a link from test1.jsp to test2.jsp using
... and make a channel based on test1.jsp. The channel will display the link as "http://mydomain/portal/test2.jsp" and result in "Error: page not found". I want the link to point to
/etc/opt/SUNWps/desktop/default/MyCustomProvider/test2.jsp
To summarize my questions,
1) Where should the web app be located in the Portal server?
2) How to make a link inside one jsp page (channel) to point to another page inside the same folder?
Thank you in advance

Hello Karthik,
I just tried to solve my problem with your suggestions, unfortunately, my JSP channel still doesn't work :(
The portal server keeps reporting "Server Error..." when I tried to add query at the end of the href.
Do you still have any other suggestions?
Thank you

Video Format Total Solution: How to Convert and Edit Video on Windows/Mac

More and More video formats are coming out with different video encoders and it makes our spare time more and more colorful. However, it is not to say that there is no problems. Actually, different video formats make it difficult to share video with others, even your own camcorder and iPod. Is there an easy way to convert videos effectively. Yes, there is.
In this article, I will show you guys how to convert videos on windows and mac.
Part 1. How to Convert and Edit Videos on Windows
For Windows users, you need a Video Converter(http://www.aiseesoft.com/total-video-converter.html) to do that for you.
Here I use Aiseesoft Total Video Converter(http://www.aiseesoft.com/total-video-converter.html)
Step 1: Download and install Aiseesoft Total Video Converter
After you download it to your computer, double click it and it is really easy to install.
You just need to click “next” and it will complete it in seconds. It will automatically run after installation.
http://www.aiseesoft.com/images/guide/total-video-converter/screen.jpg
Step 2: Load Video
Click “Add File” to find the video that you want to convert and click “open”. It will be loaded automatically.
Step 3: Select the target to decode
In the “Profile” drop download list you can find your target according the usage of your output video, such as if you want to put the video on your iPod touch, you can select the “iPod” in the first list and “iPod touch 2 MPEG-4 640*480(*.mp4)” in the second list.
Step 4: Set Advanced Parameters
After you select the right output profile, you can click “setting” button to set your advanced parameters. You can adjust video and audio settings separately. In video section, you can change “video encoder”, “resolution”, “frame rate”, “video bitrate”In audio section, you can change “audio encoder”, “sample rate”, “channel”, “audio bitrate”If you want to save this profile and settings and use it next time you can click “save as” button to give a name to it. And the next time you want to use it you can find it in the profile list named “user defined”.
Step 5: Choose a Destination
To browse and find a output folder for your output files or just the default one.
Finally, Click “Convert” button to begin your conversion, here in the converting
interface you can choose “shut down the computer when conversion complete” or “open output folder when conversion complete” or you just do not choose neither one.
Tips: How to Edit the Output Video
This video converter is also a video editor, you can use it to edit your output video as follows:
http://www.aiseesoft.com/images/guide/total-video-converter/effect.jpg
1. Effect:
You are allowed to adjust the “Brightness”, “Contrast”, “Saturation” and you can choose the “deinterlacing” to make the video more enjoyable.
2. Trim:
In “Trim” section you can pick up any part of the video to convert.
There are two ways to select the part of the video you want. One is set the start and end time in the box. The other one is to drag the start and end button in the processing bar.
3. Crop:
This function allows you to choose a certain play area to convert. That means you can choose a part of the screen you like to convert. For example, you just like the tv in the middle of the screen, then you can drag the frame around the preview window to select the tv and the output preview will show you the output video.In this section you can also choose the “zoom mode”, such as “keep original”, “full screen”, “16:9”, “4:3”.
4. Watermark
In the section, you can add a watermark on the output video to show people something, such as your name, website, studio name or other things. The watermark could be words and picture. You can adjust the transparent of the watermark easily to make it more beautiful.
Part 2. How to Convert Video on Mac
This time you need a Video Converter for Mac(http://www.aiseesoft.com/video-converter-for-mac.html)
Step 1: Add File
Click “Add File” button to load the video you want to converter
http://www.aiseesoft.com/images/guide/mac-video-converter/steps.jpg
Step 2: Choose profile and adjust settings
You can find your output video format from a drop-list called “Profile”You can also adjust the specific settings of the output video, such as “Resolution”, “Bitrate”, “Encoder” and so on.
