database backup and recovery can be performed at three levels, the database administrator can reasonably plan the tablespace based on this feature to Improve the Performance of database backup and recovery. For example, in DB2 databases, LOB and other large data types are well supported. However, after all, its capacity is relatively large, and sometimes its database capacity may reach 1/2 of the total dat

We believe that everyone in the DB2 Data Import Operation knows that some problems still need to be noted during the import process. The following describes four precautions for DB2 data import, for your reference. Before putting a database into production, the database administrator often needs to import a large amoun

idle every day or every week. With this plan, the backup efficiency can be improved. Similarly, the recovery can also be performed at the tablespace level during recovery to shorten the database recovery time. The core of this solution is to separate large data types such as LOB from common tables and store them in different tablespaces. Then, the LOB tablespace and the non-LOB tablespace are managed separately for separate backup and recovery to imp

Digital type. 1. SMALLINT---Short integral type, the range is -32768~+32767, once used less 2. Int/integer---Integral

This article mainly describes the data replication and migration methods of IBM DB2. The following describes the data replication and migration methods of IBM DB2, we hope that you will have a better understanding of data replication and migration in IBM

Common Data Types of DB2 include: 1. Digital type. 1. SMALLINT --- short integer, range:-32768 ~ + 32767, less than once 2. INT/INTEGER --- INTEGER, 4 bytes in the range of-2147483648 ~ + 2147483647, multiple times for auto-generated sequence or Table Record id. 3. BIGINT ---- big integer, 8 bytes. The precision is 19 BITs. It is large enough and generally seldom

. This can also greatly reduce the time to recover. Recovering a table is certainly a lot less time than recovering an entire database.Second, reasonable planning table space to improve database backup recovery performance.Now that database backup and recovery can be performed at three levels, database administrators can rationally plan tablespaces based on this feature to improve the performance of database backup and recovery. As in the DB2 database

import efficiency. The database administrator can set the n value based on the number of records. Generally, this value is not too large. However, if it is too small, it will also affect the data import performance. If the data volume is large, I usually set this value to 500. However, the database administrator must select a proper value based on experience. 4. Use the format option in the Import Statemen
