RE: JAVA400-L Digest, Vol 3, Issue 17 -- JAVA400-L

Murali,

>From my interpretation of your issues:

a. As Joe points, out JT400 will run on any java enabled platform.
b. If you want database independence, use of the jt400.jar JDBC driver only
will enable that.  What we typically do is externalize the JDBC connection
URL and driver reference in initial parms so that they can be set without
code change.  I.E.  Your application is config at runtime with the JDBC
driver and connection URL to use; your classpath includes all JDBC driver
jar files that you will use.  This enabled database independence while using
jt400.
c. The remote JDBC Driver will be somewhat slower than native because of the
network overhead however the difference is not that big.
a. DB Optimization can be critical.  Are the correct access paths and
indexes there?
b. Do you optimally set the jdbc jt400 properties?  Extended dynamic,
package cache, etc?

This makes no sense to me.  You're trying to use QTEMP, but you say that
JT400 is platform specific.  There is nothing platform specific about
JT400, it runs on any platform.  If you want your back end to be
platform specific as well, you use a factory class and generate a
different access object for each platform.
