I have a question regarding the size of the data base file written to
with the historian.
There is an automatic purge after 45 days but the size of the file
continues to grow.
Am I correct in assuming that the purged area will not be used and that
the file will just continue to grow.
If this is the case, is there any way to convert the file or compress
it in some way to recover this space & if this is done will the
remaining data be readable.
Any help appreciated.
Jon

Jon
Can you precise the MCC version and Operating system you are using ?
The behavior of file systems is quite different from VMS to ULTRIX.
Regards.
Pierre.

Greetings,
Yes, it continues to grow until you shut down the process and compress it.
Here's a quick procedure to compress.
cheers,
brad...
$! This procedure compresses MCC historical files to regain disk space from
$! data which has been purged dating back beyond the KEEP AGE from the RECORD
$! command.
$!
$ dir/size *.*MCC_HIST_ATTR012_1;
$ inquire file "Enter file to compress"
$ analyze/rms/fdl/output=purge.fdl 'file'
$ edit/fdl/nointeract/analyze=purge.fdl purge.fdl
$ convert/fdl=purge.fdl 'file' *
$ delete purge.fdl;*
$ file=f$extract(0,f$locate(";",file),file)
$ purge 'file
$ exit
