UTL_FILE writing question

• U8 NChan NSamp 2D DAQmx writing question: Digital

  The help file says that for the "Digital 2D U8 NChan NSamp' vi, each row of U8s is a channel and each column is a sample. But each sample U8 get extended to 8 bits? If so, what bit is first (MSB or LSB)?

  If this is not the case, how the U8 is sent to the material. Is the U8 a sample of port where each bit value corresponds to a line on a port? If it is this plan, so I guess if you had 3 lines in a channel, 5 bits of the U8 would be unused. I also assume that all lines in a channel would have to be on the same port.

  I guess my confusion comes because I think a somewhat broad digital as channel, while the literature seems to indicate that a digital channel can be composed of several bits.

  I don't have a DAQ DIO to confirm this, but I think the LSB of the U8 goes to port x 0 (D0), line up the MSB goes to port x line 7 (D7).  So if you had 3 lines in a channel, 5 bits of the U8 would be ignored.  Yes, all lines must be on the same port.  If the polymorphic selection is U8, then you must have 8 rows on the same port.  If the U16, two ports are concantenated to form 16 lines that correspond with the U16.

  I too tend to think of a digital channel in one line.  The terminology is confusing.  They shouldn't mention the word of all channel.  It should be ports and lines only, as port 0 line until the line port 0 7 0, then 1 line 0 port and so on.

  The expression "each row of U8s is a channel", I think that this meant that only one channel is the 8 lines of a port.  In other words, the channel is a port.  I guess they use the channel because if you specify U16, a channel could be ports 0 and 1.

• ByteArray writing question!

  I want to use Sound.Extract twice in a row to extract samples of different sounds to a single byteArray, one after the other.  It will automatically add the new data at the end of the old data, or do I have to use a special method of the byteArray class?

  sound1. Extract (soundBytes, 4096);

  Sound2.extract (soundBytes, 4096);

  Thank you!

  Yes, the data will be added.

• Insulation of the register HKCU mode

  I currently feel som with writing questions in HKCU on physical system of Applications. I want the Application to write to the physical registry on HKCU because its storage username and window/columns, default instances, locations etc for this Application it.

  Then when I put the register HKCU merged mode Applications survey of errors not being able to write the values. I check regedit and the KEY is created, but the values are not created. What I am doing wrong?

  I also tried the following, instead of setting the registry location real in the HKCU capture file, I allowed and tried to settle the whole registry merged through the package.ini fashionable, but he threw the same mistakes.

  Its packaged in Thinapp 5 on a Windows 2008 R2 server. Application works very well in the environment thinapp with the HKCU as default WriteCopy.

  Thanks for any input

  Finally, we got a stable version published this week that have solved this problem. Version 5.1 works as usual with merged record.

• When Firefox will support Norton Identity Safe once again, really

  Same issue as everyone else for the past two years. With each release, we beg to have the Identity Safe working again. We get no answer in response. Firefox is up to 50 version and still does not support Identity Safe as before. If you can not handle inserting the passwords like IE can, why should I trust Mozilla you can protect them? No need to answer until you have set. Firefox used to be a good program. There is nothing I want in Firefox that is more important than the ability to manage passwords. Nothing. So now I uninstall Firefox again.

  I've read dozens of reviews. Nothing definitive. I don't mean anecdotal cases of a version that works. I can't even understand why Norton was a stand-alone product and an extension. Some users claim that one or the other (not obvious to me) doesn't seem to work. I wouldn't be writing questions if it worked for me. As I said in my post to you, unless there is a final solution (do not have to depend on some obscure answer in a Forum), there is no interest to my use Firefox. I hate IE, but at least I get offered password.

• faced with the question when writing data to a flat file with UTL_FILE.

  Hi gurus,
  
  We have a procedure that writes the data from the table to a flat file. RAC is implemented on this database.
  While writing data if the current instance, this procedure creates two copies of the data in parts.
  
  Any body can help me to solve this problem.
  
  Thanks in advance...

  I also asked this question, but it seems no final solution...

  In any case, here are two possibilities
  (1) the directory for the file among all nodes share
  (2) run you a procedure on a specific node

  Your database server is likely to be Unix or Linux, right? Which means that it uses a single character (LF) to "new line", rather than Windows that use two characters (CR - LF) to 'new line '.
  (If you open your file with WordPad instead of NotePad it will probably look OK.)

  UTL_FILE. Put_line uses as a "new line" everything that uses the o/s database server.

  So if you want to write a file to be used specifically in Windows, you can make your own "new line" rather than using the servers.
  Use PUT rather than PUT_LINE and simply add the two characters that Windows uses to "new line":

  UTL_FILE.PUT(F,
                    I.1||'|'||
                    I.2||'|'||
                    I.3||'|'||
                    I.4||'|'||
                    I.5|| CHR(13) || CHR(10) );
  

• UTL_FILE. OPEN_FILE question to check if a file exists and is not empty

  Hello
  
  I'm writing a code in 3 separate files are created based on certain conditions of parameter for the call of the extract.
  Say that the parameters are NULL, 'A' and 'B '.
  When the Null State is passed to the call of the extract then it should create file A and B if the records are found. If this isn't the case, then create empty files.
  It is possible that the setting of the extract is just 'A', then it would create a file say no zero and B with file from scratch.
  Now when the extract is called with the parameter 'B' and if the file already exists and is not empty then I shouldn't touch/crash with empty folders.
  Is there a simple way I can do this to check if a file exists and is not empty?
  
  I use
  OPEN_FILE
  (gv_utl_file_path
  lv_file_name
  lv_file_handle
  );
  
  Help, please.

• Questions about the parameters of database using a fast recovery area and the writing of two copies of archived redo logs.

  My databases are 11.2.0.3.7 Enterprise Edition. My OS is AIX 7.1.

  I am to convert databases to use individual zones of rapid recovery and have two questions about what values to assign to database settings related to archived redo logs. This example refers to a database.

  I read that if I specify

  Log_archive_dest_1 =' LOCATION = USE_DB_RECOVERY_FILE_DEST'

  the names of newspapers archived redo written in the default quick recovery area is '% t_%S_%r.dbf '.

  In the past my archived redo logs have been appointed based on the parameter

  log_archive_format='GPAIDT_archive_log_%t_%s_%r.arc'

  I think log_archive_format will be ignored for logs archived redo written in the fast recovery area.

  I am planning to write a second copy of the archived redo logs based on the parameter

  ALTER system set log_archive_dest_2 = ' LOCATION = / t07/admin/GPAIDT/arch.

  If I do this, the copy of logs placed in /t07 will be called '% t_%S_%r.dbf' or 'GPAIDT_archive_log_%t_%s_%r.arc '?

  Before my use of a fast recovery area, I used the OEM 12 c Console to specify settings of backup of database that has been deleted and archived redo logs after 1 backup. Oracle manuals say rather specify a deletion of "none" policy and allow Oracle delete newspapers in the area of fast recovery if necessary. Since I got to keep a second copy of these log files in /t07 should I keep the policy that says to delete logs after 1 backup? If I don't do that, how will they removed from /t07?

  Thank you

  Bill

  If I do this, the copy of logs placed in /t07 will be called '% t_%S_%r.dbf' or 'GPAIDT_archive_log_%t_%s_%r.arc '?

  They will be "GPAIDT_archive_log_%t_%s_%r.arc". LOG_ARCHIVE_FORMAT is only ignored for directories under OMF.

  Since I got to keep a second copy of these log files in /t07 should I keep the policy that says to delete logs after 1 backup? If I don't do that, how will they removed from /t07?

  You can hold the deletion policy as it is. Oracle documentation, defining the STRATEGY of the ARCHIVELOG DELETION: "the deletion of archived newspaper policy applies to logs archive destinations, including the area of fast recovery."

  I guess that the problem is caused by

  v_utl_filehandler := UTL_FILE.FOPEN(v_file_dir, v_file_name, 'r');
  

  Is the path to the directory "MAIL_DIR" exists in your database server?
  The file 'mailattachment.doc' exists in this path?
  You have read access to this path?

  You can check the path of the directory with:

  select * from all_directories where directory_name='MAIL_DIR';
  

  When the directory does not exist in this table, you need to create (such as s/n):

  CREATE DIRECTORY MAIL_DIR AS 'yourdirectory';
  

  To grant read access to the DBA, you need:

  GRANT READ ON DIRECTORY MAIL_DIR TO ; 
  

  (Overall precondition is that the oracle user (operating system - the user running your oracle instance) can access the given directory).

  Concerning
  Ramanantsoa nara

  UTL_FILE_DIR parameter has been deprecated by oracle for direcory objects because of its security problems.

  The right thing to do is to create a directory for instance object:

  CREATE OR REPLACE DIRECTORY mydir AS 'c:\myfiles';
  

  Note: This does not create the directory on the file system. Must you do and make sure that oracle has permission to write to this directory of the file system.

  Then, grant permission to users who need to access for example...

  GRANT READ,WRITE ON DIRECTORY mydir TO myuser;
  

  Then use this object directory inside your FOPEN statement example

  fh := UTL_FILE.FOPEN('MYDIR', 'myfile.txt', 'r');
  

  Note: You MUST specify the object name of directory in quotes and uppercase for this works because it is a string that references a database object name that is stored in uppercase by default.

• Questioning Transacation writing table

  Please help me in writing a query.
  I have a transaction table that has columns as transtype, ONC, kno, sno and has data as follows
  
  SNO kno ONC transtype

  Add 1 1 1
  Add 2 1 4
  Add 3 1 2
  4 1 4 remove
  Add 5 2 1
  6 2 3 remove
  7 2 4 News
  
  SNO represents the serial number
  I need to retrieve data for the last transtype (transaction type) for example
  When I want to the result set with transtype 'Add' the query should not return
  line for kno ONC '4' and '1' because he later "delete" transaction.

  Ahh, maybe then this?

  select tt.*

        from trans_table
        group by kno,cno) x

    and x.cno = tt.cno -- Ditto.
    and tt.trans_type='the_one_you_want';
  

  And I'm sure it can be done 'better' with an analytic function.
