upgrade ASE database with SQL remote replication
The SQL remote replication is between ASE and ASA database. Does the secondary truncation point need to set 'ignore' before the ASE database is upgraded ? Thanks

Yes, correct.
You do need to ignore the secondary truncation point with
dbcc settrunc( 'ltm', ignore')
in the ASE database before upgrading. Of course your log should be totally
drained using ssremote -i, before doing that.
After successfully upgrading you have to set that back to 'valid'

If the trucation point was reset, then user need to have new database after the upgrade, if not data from remote & server are not in syn ???? Is it true ???? thanks,John

The ASE upgrade will fail unless you remove the LTM truncation point so it MUST be removed (unless you never want to upgrade). And yes, the ASE upgrade WILL typically create a new log (destroying the original contents of the log). This is acceptable from a replication synchronization stand point as long as there is nothing left in the log. That is done by running SSREMOTE -i before removing the LTM truncation point. Anything worth keeping is store in the stable queue and those are just tables (mostly sr_transaction) that are unaffected by the by the upgrade. Since the stableQ remains intact synchronization is never lost. <John> wrote in message news:AAA78CF1E0EFCDCD006B814485256D66.0077FA1D85256D65@webforums... > If the trucation point was reset, then user need to have new database after > the upgrade, if not data from remote & server are not in syn ????

While I am on the topic, I forgot about the keyword check issues you will
also run into. Some SSRemote tables contain "option[s]" as a column name
and that will cause the checkreswords to fail.
See the online tech doc http://www.sybase.com/detail?id=1016103
"Upgrading an ASE Server that has implemented SQL Remote Replication "
for more details on this. You should read through this doc in it's
entirety ANYWAY
but for a quick reference to the problem check out the sections titled "A
checkreswords Note "
and "Amendment to Note on checkreswords: " paying particular not to the use
of BCP for
NT to sidestep issues on that platform.
This document is a little dated so some things my have changed since it was
written so
take the process to heart and measures to deal with the issues and you
should be in
good shape. But remember to take backups and test your upgrade to see if you
are
going to hit anything else. If you do, do not hesitate to contact Sybase
Technical support
about any ASE upgrade problem.
sr_remoteoptions and sr_remoteoptiontype contain a reserved word column
called "option".

ASE to ASE replication using SQL Remote
Since 11.9.2 comes with SQL Remote, can I use it for replication from ASE to ASE instead of a more expensive Replication Server? Yes you can. A couple of considerations: 1) SQL Remote is not intended for near real-time replication. Even with the new hover mode features, you should plan on at least 1 minute latency in each direction. 2) SSXtract does not support automatically extracting a remote ASE database. You will have to manually configure the remote and consolidated databases, including the initial synchronization of data before you start replication. This is certainly...
