  This metafile is intended for monitoring for application that
  every several seconds updates file-flag "imalive.tmp" (it
  re-writes this file with the text containing the current
  timestamp: "#2007-02-23 15:04: 17#"). We interested in
  situations when application hangs (and stops to update this
  file), so we use "//SUMMARY" directive and check "Occurences"
  attribute for non-ZERO value.
  This did work OK, but we was needed to modify Regional Options
  on this machine. After that the appropriate UA application
  stopped to work, and the following messages have been appeared
  in its log file:
  (45DECF80.0006-3FC:kum0nget.c,295,"KUM0_Fgets") Error: Unable to
  convert string from windows-775 to UTF-8. NLS2 Error: 37

  file
  monitoring from the beginning of the file.

  ")

  ") Could not open converter for subtext <?>, error
  <U_FILE_ACCESS_ERROR> This set of messages repeated many times
  (on each update of iamalive.
  tmp file), so this log file grows very quickly.
  After adding "Locale=en_US Codepage=US-ASCII" parametes to
  //SOURCE
  statement of metafile the UA application started to work again
  and
  "Error: Unable to convert string..." message disappeared from
  log;
  however, other messages ("Could not open converter for
  subtext...")
  still continue to appear.
  It seems that problem exists with File DP only because Script DP
  on the same machine works OK without any modifications.
  What is the reason of this messages? What can we do to avoid
  them? Is it possible to avoid also the message "File
  C:\C2D3K\iamalive.tmp switched or re-creation detected"?
  
  
  As I wrote during PMR opening, this is a short text file that
  contains the current timestamp in the following format:
  
  #2007-03-02 15:41:10#
  
  It contains just one string (ending with CR-LF), total file
  length is 23 bytes. It could not contain 100 lines because
  every time this file is entirely re-written (it always contains
  just one line).
  
  As you can see from the example above, the iamalive.tmp file
  contains only ASCII text characters (digits, space, hash, dash
  and colon). It doesn't contain any letters - neither English
  nor non-English (Russian or Latvian).
  
  As I wrote in the my initial message, the initial (working)
  configuration was the Windows 2000 Professional system with the
  system default locale (in Regional Options) set to "Russian".
  In this configuration the following metafile worked OK:
  
  **** cut here ****
  //APPL Payord @Applications on the PAYORD machine
  *
  //NAME C2D3KFlag P 65        @Checking of C2D3K (Kondor Ticket
  Importer)
  flag-file update
  //SOURCE FILE C:\C2D3K\iamalive.tmp TAIL
  //SUMMARY 60 Force
  //ATTRIBUTES
  FileContent        R 25 SKEY=1 @Content of the monitored file
  **** cut here ****
  
  The only side effect was that every file update added the to the
  log file the new line of the following type:
  
  (45DEDA1E.0000-400:kumpfile.c,2561,"KUMP_FileServer") File
  C:\C2D3K\iamalive.tmp switched or re-creation detected.
  Restarting file monitoring from the beginning of the file.
  
  After changing system default locale from "Russian" to "Latvian"
  this application stopped to work. The log file contained a lot
  of lines of the following type:
  
  ---- cut here ----
  (45DECF80.0000-3FC:kumpfile.c,2561,"KUMP_FileServer") File
  C:\C2D3K\iamalive.tmp switched or re-creation detected.

  ---- cut here ----
  
  We had found in documentation info about CODEPAGE and LOCALE
  parameters (kindly quoted by you). After adding these
  parameters to
  
  //SOURCE
  
  statement our metafile becomes the following look:
  
  **** cut here ****
  //APPL Payord @Applications on the PAYORD machine
  *
  //NAME C2D3KFlag P 65        @Checking of C2D3K (Kondor Ticket

  //ATTRIBUTES

  **** cut here ****
  
  After that the UA application started to work; however, the log
  file
  continue to add the following lines for every iamalive.tmp file
  update:
  ---- cut here ----
  (45DEDA1E.0000-400:kumpfile.c,2561,"KUMP_FileServer") File
  C:\C2D3K\iamalive.tmp switched or re-creation detected.
  Restarting file monitoring from the beginning of the file.

  ") Could not open converter for subtext
  <\\payord-new\C$\C2D3K\iamalive.tmp>,
  error <U_FILE_ACCESS_ERROR>
  (45DEDA1E.0002-3C4:kum0nmsg.c,75,"KUM0_NLS2_MsgSubparmToUTF_Util
  ") Could

  ") Could

  ---- cut here ----
  
  The current problem is that on every update of iamalive.tmp file
  (23 bytes) the UA adds several lines to its log file (almost 1
  kilobyte). It spams the log file and increase the load on
  system (especially on the disk subsystem).

Local fix

Problem summary

• Problem Description: ICU FAILS TO OPEN DEFAULT CONVERTER WHEN
  CODEPAGE IS LATVIAN
  
  Problem Summary:  The ICU ucnv_open call with a NULL converter
  (meaning, use the default converter) is failing. The
  U_FILE_ACCESS_ERROR is likely the result of an incorrect or
  unknown codepage, and shouldn't be related to the presence or
  absence of a particular resource bundle on the local system.
  
  The resulting problem is the voluminous message logging of the
  form =>
  
  "Could not open converter for subtext <?>, error
  <U_FILE_ACCESS_ERROR>"
  

Problem conclusion

• You will now only see one instance of the "Could not open
  converter' message.  The repetition of this message has been
  suppressed.
  
  
  The fix for this APAR is contained in the following maintenance
  packages:
   | interim fix | 6.1.0.6-TIV-ITM-IF0005
   | fix pack | 6.1.0-TIV-ITM-FP0007
