IBM Db2の評判・口コミ 全13件

What do you dislike?

Worst ODBC drivers I've ever used - and that says something. There are countless variations and packages, each with 32-bit, 64-bit, and multilanguage flavors. It's easiest if you use the GUI-based tools to create the System DSN (using the Windows ODBC interface has never once worked properly for us), but the GUI tools install a small DB instance wherever they're installed. I don't want that on my servers just to get an ODBC connection set up. The lightweight drivers only provide poorly documented CLI tools and store passwords in cleartext ini files.

DB2 is relatively simple to maintain and performs very well. It provides a wealth of enterprise class features (mirroring, replication, clustering, etc), and I've found the built in troubleshooting/monitoring tools to be quite handy. IBM support for the product has been excellent as well.

Recommendations to others considering the product

There are free products that perform just as well and likely have better integration capabilities with 3rd party applications. However, DB2 was the right fit for us because it worked natively with our aging mainframe.

When it has not been architected and maintained well, data retrieval can be very difficult. It is really only as good as the DBAs make it.

What do you like best?

When it is administered well, DB2 is lightening fast with even very very large tables and retrieval of your data is very easy from any programming language with the familiar and intuitive SAL language.

Recommendations to others considering the product

Stick with one platform. I am working in a shop now where we have twobdatabase platforms. It's unnecessary and just makes things that much more difficult. Keep to one. If you switch, switch completely, not halfway.

would like to see it easier to switch between character sets (such as EBCDIC to Unicode); additional query building tools would be nice to have
