331.0. "RECOVER FILE FROM CACHE" by EVTAI1::POUDRET () Thu Apr 03 1997 08:59

  
  		HELLO,
  
  
  
  
  	How can i recover files from cache if the on line files are deleted ?
  
  
  
  	Ex: After  Shelving a file (for example .txt), and deleting the on line 
  file, I use the command SMU LOCATE and I try to copy the file from the cache.
  After that , it's impossible to see something (the file is empty). The record 
  format is undefined in the cache.
  
  
  
  	Any ideas.....
  
  
  	Thank's REGIS......

What version of HSM are you using?  Prior to V2.1, EOF on the cache
files was not set correctly which prevented cache files from being
viewed (typed, etc.).  This problem was most likely introduced in
V2.0/V2.0A.  This problem did not interfere with unshelving.  Here
is a sample DUMP of one of these cache files:

Dump of file DKB500:[HSM_CACHE]AA.A$8447907406;1 on  8-OCT-1996 16:06:10.55
File ID (77,1,0)   End of file block 0 / Allocated 3

                             File Header

Header area
    Identification area offset:           40
    Map area offset:                      100
    Access control area offset:           128
    Reserved area offset:                 255
    Extension segment number:             0
    Structure level and version:          2, 1
    File identification:                  (77,1,0)
    Extension file identification:        (0,0,0)
    VAX-11 RMS attributes
        Record type:                      Undefined
        File organization:                Sequential
        Record attributes:                <none specified>
        Record size:                      0
        Highest block:                    3
-->     End of file block:                0
-->     End of file byte:                 0

If this is what you are seeing, you might want to try a SET FILE/END
on the cache file and retry your copy.

331.2Wait for ResultEVTAI1::POUDRETFri Apr 04 1997 01:2813
  
  
  	I don't remember the version of HSM, but that's right there is no 
  Problem with unshelving. I will ask to the customer to try "Set file/end", but 
  i can't give you the result before 14-apr-97, because he is to DECUS and after 
  that in Holidays.
  
  
  	Thank's for your quick answer.

331.5it's works butEVTAI1::POUDRETThu Apr 17 1997 02:5011
  
  
  				Hello,
  
  	Yes, SMU LOCATE and restore from Archive works but EOF of the file is no 
  set due to previous version of HSM, and "SET FILE/END" does not put "carriage 
  return" --> all data are sequential in the file. With "DIR/FULL", the record 
  format is "undefined, maximum 0 bytes, longest 0 bytes".
