i have a database consisting of regular or "cooked" files which i am
trying to convert to a "raw" filesystem on hp-ux 11i. what i've done is
to create, for each file, a similarly sized (slightly larger) logical
volume. following this i use the dd command to copy the file to the
logical volume. the syntax of the command i use is as follows:
dd if=/tmp/file1.dbf of=/dev/vgoracle/rfile1.dbf bs=2048
where:
/tmp/file1.dbf - original (cooked) file
/dev/vgoracle/rfile1.dbf - raw character device for logical volume
bs=2048 - block size of 2k
for some reason this is not working for all files for a reason i've not
yet been able to determine. some of the raw files "work" when i do an
alter file ... in sql*plus wheras others do not. i'm wondering if i
should use a skip=N (N is integer value >= 1) as you apparently have to
do on aix.
to summarise my questions are:
- does the method appear sound from whats been described?
- for the dd command am i performing it correctly?
