Remove the function: such as Network load, if not required, then directly remove the code it;To turn off unwanted featuresTurn off kernel mirroring verificationTurn off bootstrapper outputTurn off startup delay
Modify the generic functionality of the bootstrapper to an optimized initial loader (Initial program LOADER,IPL), which can be implemented through SPL (Second program Loader, second stage loade
Management unit).
For U-boot, the most common optimization methods are:
• Delete the function: such as Network load, if not required, then directly remove the code
• Turn off features that you don't need
• Turn off kernel mirroring verification
• Turn off bootstrapper output
• Turn off startup delay
Modify the generic functionality of the bootstrapper to an optimized initial loader (Initial program LOADER,IPL), which can be implemented through

applications using this driver must run on a DB2 client, and JDBC requests are forwarded to the DB2 server through this client.
Before using the DB2 JDBC application driver to access the data source in the DB2 UDB for iSeries or DB2 for OS/390 or z/OS environment, you must install DB2 Connect Version 8. DB2 JDBC type 2 driver supports most of the JDBC and SQLJ functions described in the JDBC 1.2 specification, and supports some functions described in

Since the compatibility and upgrade problems encountered when running the SAP environment on IBM iSeries, Linz AKH has decided to migrate to the server based on the anteng architecture, in the end, the system response speed is greatly improved.
"After the system platform completes the migration, the response time is shortened by abo

When I wrote this code, I was just a newbie, so I forgot to add the comments. I barely read the code again. Some of them may not be easy to understand and offend me. A friend has gone to my space to ask for code. I can only say sorry here. I only saw your application today. It has been several years.

Displaying a data area
You can display the attributes (name, library, type, length, data area textDescription), and the value of a data area. See the CL section of the ProgrammingCategory in the iseries Information Center for a detailed description ofDisplay data area (dspdtaara) command.
The display uses the 24-digit format with leading zeros suppressed.
