important when remote access is supported. For example, the T1 line supports 1.544 MB/s, which is only 0.193 MB/s, whereas a typical MB/sec Ethernet LAN can support 1.25 MB/s for throughput of 6 times times the T1 line. Using commands such as netstat on UNIX can monitor traffic on the connection. Use the DB2 Performance Configuration wizard (DB2 control Center)

backup and recovery functions of the database, users can use it to easily migrate a DB2 database from one physical node to another physical node. However, the backup and recovery functions of DB2 currently only support migration between homogeneous operating system platforms, for example, from Windows to Windows, from AIX to AIX. There is no dedicated tool for cross-platform database migration required by

Partition index in DB2 V9.7 A significant advantage of Partitioned indexes is that when you use the alter table attach partition and detaich partition commands to transfer data to roll-in) and roll-out, using partition indexes can greatly improve performance. In DB2 V9.7, the following types of indexes cannot

script cannot find the gzip command on the system, it will try to use the compress utility. This option can be used together with the-t sub-option, or separately: db2dback.ksh-a–z[-o ] db2dback.ksh-a-t–z[-o ] When sending data to the tar archive, the tool compresses the archive at the end. If you want to transfer data without the-t option), compress each transferred file in the target directory. Only files larger than Kb are compressed. By default, diagnostic d

Today, we mainly describe how to minimize the planned downtime of DB2 9.7 database online mode changes when modifying database objects. We all know that IBM®DB2®9.7 introduces new enhancements that allow you to change database objects and ensure that users have full access to these objects during database modification. These enhancements allow the database administrator to dynamically modify the database mo
