Murali, "JT400 is horrifically slow when using a distributed access" Can you give more details on this as I use jt400 too access database all the time cheers Colin.W http://j2ee.mine.nu/javafeed Extension 5800 Direct dial 0870 429 5800 -----Original Message----- From: murali dhar [mailto:hydchap1@xxxxxxxxx] Sent: 10 January 2005 13:31 To: Java Programming on and around the iSeries / AS400 Subject: RE: java-qtemp Hi Joe, we are not using JT400 as it is specific to AS400,any java code we write on the AS400 needs to be platform independent,Using JT400 we can never freely port Java code to run on Unix. JT400 is horrifically slow when using a distributed access, so we are using Java Proxy which uses native 400 JDBC driver which is much quicker. Thanks, Joe Pluta <joepluta@xxxxxxxxxxxxxxxxx> wrote: I'm going to assume you've used IBM's Java Toolbox for the AS/400 (known as JT400 or JTOpen, depending on which version you have). If so, you've used the com.ibm.as400.access.AS400 class, which basically allows a Java program to access an AS/400 or iSeries host. Once you create an AS400 object, you can then use it to access the rest of the host objects. For example, the ProgramCall class allows you to call a program, while the AS400KeyedFile class allows access to keyed files. I'm not 100% sure of the sequence of events, but when you create an AS400 object and then use it to call a program using the ProgramCall class, what happens under the covers is that JTOpen submits a job named QZRCSRVS for you. This job actually calls the program, and communicates back to the Java application. What I do is create a single AS400 object for my session, and then use it to create all of my ProgramCall objects. That way, they'll all run under the same QZRCSRVS job. This means that not only can I access the QTEMP library for the QZRCSRVS job, I can change the library list and even execute overrides. Pretty cool stuff. Be warned: there are (or at least there used to be) circumstances under which you may not get the same QZRCSRVS job for all of your ProgramCall objects. However, I have not run across that in a long time, and as long as you use the same AS400 object for all your ProgramCalls, you should be fine. Joe > From: murali dhar > > whats QZRCSRVS? I reuest you write few more lines , Im new to Java just > like other AS400 folks. -- This is the Java Programming on and around the iSeries / AS400 (JAVA400-L) mailing list To post a message email: JAVA400-L@xxxxxxxxxxxx To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/java400-l or email: JAVA400-L-request@xxxxxxxxxxxx Before posting, please take a moment to review the archives at http://archive.midrange.com/java400-l. --------------------------------- Do you Yahoo!?
