Creating 64 bit hash file

Das · Post by **Das** » Wed Jul 04, 2007 4:04 am

Hi All,
I wanted to create a Hashfile which can handle more than 4GB of data for look up pupose.Currently we are using 32 bit [default]hash file which can handle only upto 2GB of data .So for handing more data i think i should to create 64 bit hash file

Plese give me your valuble suggestions in this regards or any alternative solution.

Thanks in advance.

Das,

in order to store appreciably more than 2Gb in a hashed file you will, as you have already presumed, need to create a 64bit file. This cannot be done via the graphical front end, you will need to enter the administrator command line or the UV shell and issue a "CREATE.FILE {filename} DYNAMIC 64BIT" for a local file.

There are many posts in this forum regarding creating 64BIT files with additional information.

Search the forums for 64BIT to get the information you seek.

Could you expalain this process?How we can create the 64 bit hash file internally

I have used

RESIZE MyHashFileName * * * 64BIT
USING /ABC/PQR/InputDir

in DS Admistrator command
But it is giving an error "Invalid File Name sizing parameter or option on command line"

here " MyHashFileName "the name of the hash file i have created and "ABC/PQR/InputDir"is the path in which i keep the file

Please help me out why the error is coming..

Does a VOC pointer exist for MyHashFileName ?

It's hashed file, by the way, not hash file.

I have the idea how to create VOC pointer .I used the foillowing command to establish the VOC pointer

SETFILE /ABC/PQR MyHashFile OVERWRITING
after exicuting the command i got the following messege
*** Warning ***
The DICT file path name "/ABC/D_PQR"does not exist
Pointer "MyHashFile" established in VOC file"
Please suggest why it is showing this warning,Actually the given path for the file is" /ABC/PQR " but in warning its showing "/ABC/D_PQR" .. [see D_PQR]

Then i exicuted the resize command
RESIZE MyHashFile * * * 64BIT

but it is giving the same error "RESIZE : Invalid file name,sizing parameter, or option on command line "
please suggest ..[/b]

FOR VOC ENTRY............

SETFILE

: PHYSICAL PATH INCLUDING FILE NAME
: VOC ENTRY NAME
Y
DONE

FOR RESIZING..........

RESIZE [DICT] [filename] [type] [modulo] [separation]
[ CONCURRENT | INPLACE | USING partition] [64BIT | 32BIT]
