Team members,
we have db1 database and db2 database.On db2 database we have synonyms created for objects
on db1 database through database links.We are using this synonyms in a procedure in db2 which calls procedure
in db1 for insertions and deletions in db1.when we execute this procedures in db2 the result takes quite a while
i.e min 1hr.I dont know what need to be done to improve -this thro remote updations.Guys could u pls advice me on this
Oracle 8.1.5 on solaris 2.6
Your performance with remote databases depends on a couple of things:
1. bandwidth between servers
2. How and where you process data. For example, if you have a package on the local instance that pulls data from the remote instance and does a calculation on the local instance, the performance will be slow. The less that has to be pulled over the link the better.
3. I have heard about some performance problems with two-phase commits, although I have not verified these performance problems.
thanks for reply..i think two phase commit should resolve my issue.could anyone of u guys guide me how to use/enable two phase commit.
Whoa. Two Phase commit is what automatically happens when you have a transaction between two databases. There is nothing additional you have to configure.
