db2 commands

This article introduces you to examples of problems related to the DB2 license in the AIX environment and related solutions for your reference. You can use it flexibly according to your actual situation, to achieve the ultimate goal of solving the DB2 license problem. During the installation and use of the DB2 UDB product, users may encounter problems related to

subproxy exists only in a multi-partition environment (MPP) or in-node parallel environment (SMP), and may exist in all environments of DB2 V95. There is a proxy pool in the DB2 server. When the instance is started, the number of proxies depends on the instance parameter NUM_INITAGENTS ). When there is no database connection, they are in standby status, that is, idle proxy. When an external program connect

When you use commands to delete a DB2 database and create a new database, there are often database alias errors. There are two possible causes of this error: 1. this database exists in the system database directory. You can see in the control center and list db directory in the DB2CLP window. 2. The database is "removed" rather than "deleted ". Another possibility is that we used the "Remove" Database Funct

The DB2 tutorial you are looking at is: IBM DB2 Connect Introduction (1). In part 1th of this series, we initially talked about the different programming interfaces provided by DB2 Connect and the drivers that implement those interfaces. In the last few sections, we describe roughly the communication infrastructure provided by

The backup method of the DB2 partitioned database is different from that of the general backup method. The following describes how to implement the backup method of the DB2 partitioned database. Backup operations on the DB2 partitioned database: The backup operation only applies to the current partition of the partitioned database. Therefore, you must use the "db

. We recommend that you use a for loop. However, sometimes the while LOOP must be used. If there is a transaction in the loop, for example, there is a transaction that requires independent transactions in the loop, if the execution is successful, the transaction will be committed. If the execution fails, the transaction will be rolled back, to continue the next loop, you can only use the while loop. Because the current pointer is automatically closed when commit is used. In the while LOOP, if yo

issued with the checkpoint SCN. In other words, all the dirty bits in the data buffer zone are refreshed to the data file. After the initial checkpoint SCN, no new checkpoint SCN will be issued. For data files that are not in online backup mode, the subsequent check points will add SCN to their file headers. When "Alter Tablespace ts_name End Backup" is issued, the checkpoint SCN is recorded again in the file header of the online Backup data file. The Begin Backup and End backup

DB2 data movement is expected to happen frequently. The following describes four file formats of DB2 data movement in detail. If you are interested, take a look. The role of DB2 data movement: To transfer data between different database management systems, data movement is usually the most practical method, because any database management system supports common f
