Subject: RE: How to downgrade database
from 8.1.5 to 8.0.6 - Urgent Help P
The
safest way is to do a full database export, to create a new 8.0.6 database
instance and to import the data in the new database. You have to
see for inter-version specifics - you might need to use 8.1.5 import version
to import in the 8.0.6 database - you have to check that, but it is for sure
doable.
<SPAN
class=293381916-17052001>
If
at all possible, I would not delete the original 8.1.5 database before I am
fully done with the import and I test that 8.0.6 is working
fine.
<SPAN
class=293381916-17052001>
If
you do not have enough space for 8.1.5 + export file + 8.0.5 (and you are on
unix) you might use the named pipes for export/import (again make sure that
the exp/imp versions are OK):
<SPAN
class=293381916-17052001>
<SPAN
class=293381916-17052001>
<P class=BodyCopy
style="MARGIN-LEFT: 0.25in; TEXT-INDENT: -0.25in; mso-list: l5 level1 lfo12; tab-stops: list .25in"><SPAN
style="FONT-FAMILY: Symbol">·<SPAN
style="FONT: 7pt 'Times New Roman'">
create a named pipe:
$ mknod p_expimp p
<P class=BodyCopy
style="MARGIN-LEFT: 0.25in; TEXT-INDENT: -0.25in; mso-list: l22 level1 lfo13; tab-stops: list .25in"><SPAN
style="FONT-FAMILY: Symbol">·<SPAN
style="FONT: 7pt 'Times New Roman'">
export from the source database to the pipe:
$ exp userid=<I
style="mso-bidi-font-style: normal">src_username/<I
style="mso-bidi-font-style: normal">password file=p_expimp <I
style="mso-bidi-font-style: normal">OtherParameters
<P class=BodyCopy
style="MARGIN-LEFT: 0.25in; TEXT-INDENT: -0.25in; mso-list: l30 level1 lfo14; tab-stops: list .25in"><SPAN
style="FONT-FAMILY: Symbol">·<SPAN
style="FONT: 7pt 'Times New Roman'">
at the same time importing from the pipe is started:
$ imp userid=<I
style="mso-bidi-font-style: normal">trg_username/<I
style="mso-bidi-font-style: normal">password file=p_expimp buffer=1024000
<I
style="mso-bidi-font-style: normal">OtherParameters
