IBM Rational Synergy iFix 7.1.0.1.03 for version 7.1.0.1
IBM Rational Synergy Fix Pack (7.1.0.2) for version 7.1.0.1

APAR status

• Closed as program error.

Error description

• 0) Tested on windows 2003-R2 with Synergy 7.1.0.1-02
  
  1) Unpack a new empty database from base.cpk
  -Start a session as ccm_root.
  -Create a project with a default task.
  -Create a new type 'iso' for example, based on the .iso
  extension, with supertype binary.
  -Get a big iso file, at least 2.5Gb.
  The file used for the test is a Linux iso image of 2,716,860,416
  bytes.
  So it contains plenty of binaries, etc... (not simply some text
  files).
  
  -Add this file in the workarea of your project, and reconcile to
  put it under control.
  -Check in the task to integrate the file.
  -Run a 'ccm fs_check' to be sure there is no error and that the
  file is archived.
  -Stop the session
  
  
  2) Run a backup of the database with the 'ccmdb backup' command.
  The backup command returns no error.
  Unpack this new backup.
  The unpack returns the error:
  ##
  Extracting pack file c:\temp\test2.cpk.
  funzip error: out of space on stdout
  ERROR: Cannot extract pack file c:\temp\test2.cpk
  ##
  
  The size of the database directory in the Windows Explorer was:
  5,432,485,516
  The backup file created was 13Mb!!!
  
  Additional Tests:
  3) Locate the archive for the iso object in the directory
  <base>/st_root/archive/....
  In my test, it was:
  \\iedu-ggtest\ccmdb\iedu711\st_root\archive\ccm_delta\source\bin
  ary2\iso\#3439\0251672094.1.zip
  Its size is: 2,686,142,646 bytes
  
  a) Emulate the pack command creating the cpk file:
  Use the following command to create a backup file of the file
  \\iedu-ggtest\ccmdb\iedu711\st_root\archive\ccm_delta\source\bin
  ary2\iso\#3439\0251672094.1.zip
  
  ##
  cmd /c '%ccm_home%\bin\util\bsdtar.exe cfv - -C
  \\iedu-ggtest\ccmdb\iedu711\st_root\archive\ccm_delta\source\bin
  ary2\iso\#3439 0251672094.1.zip| %ccm_home%\bin\util\ccm_zip.exe
  -v -6 > c:\temp\test.cpk' > result1.txt 2>&1
  ##
  This command is using the Synergy bsdtar.exe and ccm_zip.exe
  tools.
  This is the same command used to create the Synergy backups
  under Windows except that I added the switch '-v' for the
  verbosity.
  (it would be great to have this option in the ccmdb
  backup/pack/unpack command).
  
  The log returned the following information:
  ##
  adding: -.....a 0251672094.1.zip
  .....................................................
  (in=2686146560) (out=2606934) (deflated 100%)
  total bytes=2686146560, compressed=2606934 -> 100% savings
  ##
  This result shows that the archive has been compressed by the
  backup from 2,686,146,560 bytes to 2,606,934 bytes.
  Meaning a compression of 1000.
  => There is obviously a problem with the compression here.
  
  b) Emulate the unpack command extracting to extract the files
  from the cpk (backup) file you've just created:
  -First, create the directory:  c:\temp\test2
  -The command used by the 'ccmdb unpack' is:
  ##
  cmd /c '%ccm_home%\bin\util\ccm_unzip.exe < c:\temp\test.cpk |
  %ccm_home%\bin\util\bsdtar.exe xfv - -C c:\temp\test2' >
  result2.txt 2>&1
  ##
  -Notice the switch '-v' for the verbosity.
  This command returns in the result2.txt log:
  ##
  x 0251672094.1.zipfunzip error: out of space on stdout
  ##
  => This is the same error as the one returned by the ccmdb
  unpack command!.
  
  There is np space problem on my test machine.
  There is only one partition with 60Gb free.
  

Local fix

Problem summary

• ccmdb backup truncates the cpk file
  

Problem conclusion

• This problem was solved in Synergy 7.1.0.1-03.
  Implement bsdtar to support single file bigger than 2G on
  Windows.
  

Temporary fix
