MaxDB and compressed NTFS harddisk

[Former Member]

Hi all,

i'm not really sure, if this is the right place to post this, but anyway.

I've had severe MaxDB problems after compressing a NTFS harddisk partition. The DB generates a Windows application error on startup and fails. After decompressing the sapdb folder, everything works fine again. Is MaxDB generally restricted to run on uncompressed drives only or is this a bug?

MaxDB version is KERNEL 7.5.0 BUILD 007-123-057-359, OS is XP Professional, SP1.

Hi,

just to clarify: MAXDB will not run on compressed (NTFS) disks, it's not a bug, it's meant that way.

Hi Roland,

would it have been possible for me to install MaxDB on an <b>already</b> compressed drive or is there a check somewhere? I did the compression after the installation.

Hi Stefan,

maxdb's coding doesn't permit starting on a compressed drive, I'm not sure about the installation, but if it's not startable...

A database in general uses very low level functions to be as fast as possible. Therefore you should expect that you run into problems when using compressed drives.

Just don't do it.

Hi Benny,

you are right. I ran into this by accident, since i compressed the drive after the engine installation procedure. Since i know it now, i won't do it once again.

Thanks and regards,

Stefan
