Home -> Community -> Mailing Lists -> Oracle-L -> merge command
I'm testing an update process using MERGE. For reasons too complicated
to go into (can you say "corporate politics"?) I have a login app in
one database and the "real" admin users tables in another database. The
users don't want to use database links to read the admin table
real-time, they worry about the possibility of one database being down
for maintenance and hanging up the second app. So I've got copies of
the real tables in the login database.
Clear as mud so far?
Now I have to update the tables in the login database with the real data on a regular basis. I *could* set up replication, but these are tiny tiny TINY tables (I might have 34 rows in the largest one) and it's just not worth the effort.
So I thought, use a database link to get the real data and use MERGE to get the data in. I get to play with a new command I've never used and pretend to be a real 9i DBA. First run through, so it should all be the INSERT part of the MERGE command.
Works like a charm on the 5 row table.
I keep getting "end of file on communication channel" on the 34 row table. This happens within 5 seconds of hitting enter.
9.2.0.2 on Sun Solaris. For testing purposes, I'm actually linking back into the same database, different schema, via a dblink.
I've looked at Metalink, the docs and even a bit into Tom Kyte's site (thanks Paul).... nothing.
Any suggestions on where I should look next?
I *could* just truncate and reload but the users are paranoid about the truncate happening and then not being able to reload and being left with no admin data
