Concurrent Program errored out without generating  logfile
==========================================
Concurrent manager log file is empty
Error:The log file for this request is empty.The concurrent manager may have encountered an error while attempt to create this file.

solution:

check the softlink on that excutable..may be it is pointing to wrong location.

Example:
Please check the executable file .It seems its not present to be executed  .

/oracle/d1/oracle/XXXXXXX/xxxxxxappl/xxvm/11.5.0/bin
[applmgr ora-xxxx-app-1] ls -lrt XXvv_xxxx_XXXXXXX_xx_XXXXXXX*
ls: XXvv_xxxx_XXXXXXX_xx_XXXXXXX**: No such file or directory

Some times after soft link creation also the concurent program  will fail if the file format is not correct .Hence  follow the exact below method :

1.Convert File format into unix dos2unix filename.prog 

=> dos2unix   XXvv_xxxx_XXXXXXX_xx_XXXXXXX.prog

2.  make sure that file has execution permissions chmod 777 $XXG_TOP/bin/xxg_sqldumper_interface.prog 

=> chmod 777 xxvv_xxxx_xxxxxxx_xx_xxxxxxx.prog 

3.check symbolic link ln -s $FND_TOP/bin/fndcpesr/ $<PROD_TOP>/bin/<host file name without 

extension>. 

=>ln -s $FND_TOP/bin/fndcpesr/     XXvv_xxxx_XXXXXXX_xx_XXXXXXX

Now check by running the concurrent program .
