Do you mean with the additional Replication Server (commercial) or is there another way? Are you using replication with that version of sybase? We are deciding between sybase 11.0.3.3 and Interbase 6 and are currently leaning towards Interbase because we don't know how Sybase will support this product in the future. What if they decide not to support JDBC X.X for the free versions at some point. then you'll be forced to buy the commercial version. that's why we felt we'd go for Interbase if it works well with orion. We have installed it here and have migrated one large orion application (ejb and direct sql) that was running on adabas to interbase. that took two days and seems to work very well. it's a shame Software AG failed so miserably making Adabas D a well-supported product. they were the first commercial database vendor to port to linux and the software has all the features you need (including clustering support) at an unbeatable price. somehow nobody outside germany seems to use it, which is why we'll eventually be dropping it (no community support). robert Very full featured and quite fast from my experience, a true enterprise RDBMS.

RE: Interbase Details [Was HARDWARE FOR J2EE apps]
Sybase JDBC drivers are called "JConnect". Current version is 5.2 (for JDBC2) and 4.2 (JDBC1) I had a few problems with them ages ago and bought a commercial driver - never tried again, but they have evolved I think.

Re: Interbase Details [Was HARDWARE FOR J2EE apps]
it's a shame Software AG failed so miserably making Adabas D a well-supported product. they were the first commercial database vendor to port to linux and the software has all the features you need (including clustering support) at an unbeatable price. somehow nobody outside germany seems to use it, which is why we'll eventually be dropping it (no community support). Robert, dont you think that this is going to improve now that SAP DB (same as ADABAS D?!) is on the way to open source??

The drivers can actially be found at sybase ;-) It took me a couple of hours to find them their site really sucks in relation to navigation. I'm using JConnect 5.2 and it's a pretty good driver (much better imho than for example DB2 Oracle drivers. I've heard of one bug, but haven't seen it myself, it's simmilar to the bug in the older MySql (mm) drivers, and does not allow images of more than 32k to be inserted into or obtained from the database. But I agree with the above mentioned. IMHO the free linux version is the best i've seen so far. Highly scalable, quite fast (select * from where pk='x' on a table with more than 7 million records is almost instantanious and several joins on tables with more than 7 million records goes in less than a second), it's slow (imho) in populating the db (700 records took about 14 hrs (4 on mysql!)). The docs are great (about seven books(ps) with 500+ pages) sven -- == Sven E. van 't Veer http://www.cachoeiro.net Java Developer [EMAIL PROTECTED] ==
