Generate the analog waveform based on the data file
I want to create an analog voltage output that follows I have a data file (excel, csv, text (which is easy)). The data file creates a waveform with equal time between steps (dT =.0034 sec). After the output through all the data points, I want it repeat indefinitely.
What is the best way to create the waveform of a data file?
To create a type of waveform data, calculate the dt by subtracting two values in column 1 and get the array of Y from column 2. If you save the file as a comma separated or tab text file, you can then use the spreadsheet file read. After obtaining a 2D array, you would use the index table and the subset of table functions.
Assuming you use a capture card data OR for the output signal, you can pass a type of waveform data to a writing DAQmx and set for the generation of types.

Generate the log file for the dialog box
Hi all
I'm generating information for the dialog box as a .txt log file format. That means that if the box is checked, the log file will be give ' checkbox1 - 01.» Check the report, sizes against the information on tickets and slug jobs"is checked
If the checkbox is not checked, the log file will be give ' checkbox1 - 01.» Check the report, sizes against ticket and slug information on employment"is not checked
and also the entry "myText2" also needs to generate the log file

Hi Steve,.
There are some errors in your code.
- function 'getmyDoc' is used, but not created.
- fucntion 'getScriptPath' is created but not used. (In any case, this will not give you error)
- function 'journal' has defined two times with the same length of the parameter.
etc...
Here, I have modified your code. Try this.
var w = new Window ("dialog"); var myGroup1 = w.add('panel', undefined, 'P&&G Check List'); myGroup1.alignChildren = "left"; var checkbox1 = myGroup1.add ("checkbox", undefined, " 01.

ORA-19846: cannot read the header of the data file of the remote site 21
Hello
I have a situation or I can say a scenario. It is purely for testing base. Database is on 12.1.0.1 on a Linux box using ASM (OMF).
Standby is created on another machine with the same platform and who also uses ASM (OMF) and is in phase with the primary. Now, suppose I have create a PDB file on the primary of the SEED and it is created successfully.
After that is a couple of log, do it again passes to the waiting, but MRP fails because of naming conventions. Agree with that! Now, on the primary, I remove the newly created PDB (coward the PDB newly created). Once again a couple of switches of newspapers which is passed on to the wait. Of course, the wait is always out of sync.
Now, how to get back my watch in sync with the primary? I can't roll method until the required data (new PDB) file does not exist on the main site as well. I get the following error:
RMAN > recover database service prim noredo using backupset compressed;
To go back to November 8, 15
using the control file of the target instead of recovery catalog database

RMAN-03002: failure of the command recover at the 18:55:32 08/11/2015
ORA-19846: cannot read the header of the data file of the remote site 21
The clues on how to I go ahead? Of course, recreating the eve is an option as its only based on test, but I don't want recreation.
Thank you.
I tried like below:
1 a incremental backup of the primary of the CNS where off the eve also taken primary backup controlfile as Eve format.
2 copy the backup of the watch parts, catalogged them on the day before.
3 recovered Eve with noredo option - it fails here with the same error pointing to the 21 data file.
OK, understood. Try not to get back the day before first, rather than restore the controlfile and then perform the restoration.
Make it like:
1. take incremental backup of primary SNA, also ensures the backup controlfile format.
2. copy pending, get the location of the data file (names) by querying v$ datafile on the eve. Restore the controlfile ensures from the backup controlfile you took on primary and mount.
3. Since you are using OMF, the path of primary and standby data file will be different. (
/ ). If you require catalog data from the database files pending. (Reason: you restore controlfile from elementary to step 2, which takes place from the main access road). Use the details that you obtained in step 2 and catalog them.
4. turn the database copy by RMAN. (RMAN > switch database to copy ;))
5 Catalog backup items that you copied in step 2.
6. recover the standby database using 'noredo' option.
7. finally start the MRP. This should solve your problem.
The reason I say this works is because here, you restore the controlfile to primary first, which will not have details 21, datafile, and then you are recovering. So it must succeed.
In the previous method, you tried to first collect all the day before, and then restore the controlfile. While remedial classes, always watch seeks datafile 21 as he controlfile is not yet updated.

Get the former locations of the data files and Redo logs
Version: 11.2
Platform: Solaris 10
When we manage hundreds of DBs, we do not know the locations of all DB files these allows DBs. say a DB goes down and you have all the required RMAN backups.
When you restore the DB in a new location in the path of the new server, you must run the commands for the data files and ORLs below. But how do we know
The former location of the data files.
B. the old location of redo online stores that I can run
runalter database rename file 'oldPath_of_OnlineRedoLogs' to 'newPath_of_OnlineRedoLogs' ; --- Without this command , the restored control file will still reflect the old control file location
run { set newname for datafile 1 to '/u04/oradata/lmnprod/lmnprod_system01.dbf' ; set newname for datafile 2 to '/u04/oradata/lmnprod/lmnprod_sysaux01.dbf' ; set newname for datafile 3 to '/u04/oradata/lmnprod/lmnprod_undotbs101.dbf' ; set newname for datafile 4 to '/u04/oradata/lmnprod/lmnprod_audit_ts01.dbf' ; set newname for datafile 5 to '/u04/oradata/lmnprod/lmnprod_quest_ts01.dbf' ; set newname for datafile 6 to '/u04/oradata/lmnprod/lmnprod_yelxr_ts01.dbf' ; . . . . . }
Hello
With the help of Oracle 11.2, you can use feature 'set newname for database' using OMF.
SET NEWNAME FOR DATABASE TO '/oradata/%U'; RESTORE DATABASE; SWITCH DATAFILE ALL; SWITCH TEMPFILE ALL; RECOVER DATABASE;
After the restore and recover databases (i.e. before resetlog open) you can do to rename redolog. Just a query column member from v$ logfile and deliver ' alter database rename file 'oldPath_of_OnlineRedoLogs' to 'newPath_of_OnlineRedoLogs ';
When we use the DSO is much easier to use OMF because Oracle automatically creates the directory structure.
But when we use the file system that the OMF does not serve due DBA dislikes system generated on file system names.If you don't like OMF file system, you can use the script on thread below to help restore you using readable for datafile names, tempfile, and redo.

Defining the new path for the data files for restoring using the VALUE of NEWNAME FOR DATABASE
Version: 11.2.0.3 Linux
Today, I had to do a restore RMAN to a new server and I came across the post following RTO on the VALUE of NEWNAME FOR DATABASE

So I had to rename each file as below
I would have been better in execution of the order for each data below file$ mv 1 /fnup/hwrc/oradata/spikey/system01.dbf $ mv 2 /fnup/hwrc/oradata/spikey/sysaux01.dbf $ mv 3 /fnup/hwrc/oradata/spikey/undotbs01.dbf
Now, I think, there is no advantage in using NEWNAME SET of DATABASE to. Only the disadvantages. I did anything wrong above?SET NEWNAME FOR DATAFILE
Martin;
On the issue of the VALUE of NEWNAME FOR DATABASE, you must specify at least one of the first three of the following substitution variables to avoid collisions of names: %b f % U. see semantic entry for TO 'filename' for a description of the possible substitution variables.
You use %f
%b Specifies the filename without the fully qualified directory path. For example, the datafile name /oradata/prod/financial.dbf is transformed to financial.dbf. This variable enables you to preserve the names of the datafiles while you move them to different directory. During backup, it can be used for the creation of image copies. The variable cannot be used for OMF datafiles or backup sets. %f Specifies the absolute file number of the datafile for which the new name is generated. For example, if datafile 2 is duplicated, then %f generates the value 2. %U Specifies a system-generated unique filename. The name is in the following format: data-D-%d_id-%I_TS-%N_FNO-%f. The %d variable specifies the database name. For example, a possible name might be data-D-prod_id-22398754_TS-users_FNO-7.

To be honest, I don't really see what you have done in the op, so I can't really comment on. I see you have an export of the TTS, but that's all.
If you have followed all the list I mentioned (you did write the TTS reading?), then you can try to save the file with RMAN, but I suspect that it does not work. Do you get the error even if you move the shared location (/ donneesimporter) to a local directory on the target area? Maybe he doesn't like the fact that it's a NFS mount (or whatever the proportion is).
Or maybe it's because you going to 10.2.0.4 10.2.0.5. I have always had the same group of patches and updated once I had plugged the tablespaces on the target database.

easy transfer can be used to reload the data files after formatting hard drive?
I have been informed by level microsoft 2 I have to reformat my hard drive to fix the problem with windows backup (snapshot won't work). easy transfer will copy all THE data files, including OUTLOOK 2007 on hard drive and then I can reinstall on reformatted drive.
Easy transfer copy some things but not all things. He does more that can make a simple copy/paste (such as the settings for example) but, for example, not programs transfer (those who need to be put back in place). Here is a description of what it does (and does not): http://support.microsoft.com/kb/928635. It will transfer Outlook 2007 PDF files and other personal data if they are selected - you need to know which files you need and where to select them - but it won't transfer the program (which must be put back in place). It must be run before you reformat the hard disk to collect data and then you can transfer everything what you have registered once the system is re-installled. You would do the re-setup prior to the transfer.
I hope this helps.
Good luck!

Hello
The process of database have a file handle for the data file - this remains even when the file is deleted (it disappears from the normal file system navigation)
You can see if you have lsof installed
just try
lsof | grep datafile_name
Once the database is restarted and the released file handle so you will not be able to do this any more - and in fact you will get errors when it can't find the file.

}I get error RMAN-06023: no backup or copy of the data file found
I'm trying to restore a database backup from 5 days ago and I use this backup control file.
I'll close this discussion and continue to involve the Oracle. Thank you all for your help.

You cannot change the data file
Hi all
Using Alter database datafile ' C:\Oracle\APP\ORADATA\...\USERS01. DBF' SIZE 100M;
getting this error.
SQL > Alter database datafile ' C:\Oracle\APP\ORADATA\...\USERS01. DBF' SIZE 100M;
Error report:
SQL error: ORA-01237: do not extend datafile 4ORA-01110: data file 4: ' C:\Oracle\APP\ORADATA\...\USERS01. DBF'
ORA-27059: reduce file size
OSD-04005: SetFilterPointer() failure, unable to read the file
s/o-error: (OS 112) there is not enough space on the disk.
01237 00000 - "cannot extend %s datafile.
* cause: year Operating system error has occurred during resizing.
* Action: Resolve the cause of the error of operating system and start the command
I understand that the OS space is full and I guess this isn't specific Oracle error, but certainly an OS level error, someone could suggest me how to deal with the erasure of space, is it possible to erase and reuse the data files? Please suggest.
Help out me
Thank you and best regards,
CabbageYou need create more space by deleting unnecessary files or narrowing of the files.

Is there no matter what it is called line high water mark for the data files?
Hi all
I'm a little confused about that. Many links suggest that HWM is for Segments (data index etc.). But at the same time, I see a lot of discussion (on this forum as well) which suggest that the HWM is an attribute of the data file.
for examplefind a watermark on a data file
Please specify.
Thank you
