import databases to a new target system without downtime. The benefit of migrating to IBM DB2 with SAP software upgrades and/or Unicode conversion is that it not only avoids repeated projects such as backup and testing, but also effectively controls migration costs.
Migration Process: heterogeneous system ReplicationCCBCC uses the standard SAP Method for migration. This method is also called "heterogeneous system replication" or "
management. It enables you to monitor application, system statistics, and system parameters in real-time and historical mode. In addition, DB2 PE can also help you analyze performance bottlenecks and provide tuning recommendations for system and application performance.
With performance Expert, you can manage various types of hybrid DB2 systems through a single user interface. It integrates performance mo
During the installation and JDBC development of DB2, you may encounter some common problems and make a record to be noted:
1. License
Whether the DB2 version is genuine or not depends on the license, but there is no prompt during the installation process. License installation:
Db2licm-A [path]/db2ese. Lic
If the license is incorrect, the biggest impact is that the database cannot provide services to servers
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

The enhanced DB2 driver for JDBC and SQLJ complies with the JDBC 3.0 specification. It also supports SQLJ statements. The functions and features of SQLJ statements are similar to those of most JDBC methods.

The no op operation can change the optimizer's working mode by downgrading a filter from conformity to non-conformity, but it is only useful on z/OS, the LUW optimizer is not affected. This change will also affect the connection sequence, index selection and Connection Methods of a table. Predicate-level technologies can be used together to obtain desired results. The pointer in our example does not respond to the combin
This article will describe the basic types of connecting to DB2 in java. There are four types for your reference.
First: at present, IBM has not provided the JDBC driver for TYPE 1.
Type 2 driver: COM. ibm. DB2.jdbc. app. DB2Driver. The driver is also located in the package DB2java.zip. JDK must be able to access DB2's DB2jdbc. dll and so on.

To solve this problem, you can use the following methods:
1) Stop all DB2 Processes
# Ps-ef | grep db2
If a DB2 process exists, it can be forcibly
