Upgrade to the lastest version

[cchen]

hi,
We used the version 7.7. But we don't sure whether it deserve to upgrade to 8.4.
We have some performance troubles about reading/writting database. I have read
the version history document and focus on these items:

version:8.2.90
• The performance when working with parameters is improved
• The performance of reading and writing OracleObject attributes in the OCI mode is significantly improved

version:8.2.80
• The possibility to speed up the stored procedure execution with the ExecuteReader()/ExecuteScalar() methods of OracleCommand, when using CommandType.StoredProcedure, is implemented via the new connection string parameter "Describe Stored Procedure" (Default value is True) and the new ImplicitRefCursors and IsTableValuedFunction properties of the OracleCommand class


So is there any more details about these performance improved like how much percentage of the performance improved when compared former version,etc.

If these performance do not be improved obviously, we may give up upgrade.

We could not tell you a detailed information about how much the performance is improved, because for different cases performance improvement is different.

You can use the latest Trial version of dotConenct for Oracle with your application to determine how much performance improved and decide whether to upgrade to the new version.

If you have already used the Trial version of dotConenct for Oracle before, we have sent you the instruction on how to use the extended trial version.
