How to Export a DB2 Database

Understanding DB2 Export Command

The DB2 export command is a powerful tool used to transfer data from a DB2 database to an external file. This command is essential for creating backups or moving data between DB2 databases. It supports SQL or hierarchical data exports and requires appropriate permissions for database access. Parameters such as TO filename, OF filetype, and others are crucial for its execution.

Exporting Data Step by Step

To ensure a successful data transfer, use the DB2 export command with the PC/IXF file format, which is specifically recommended for DB2 to DB2 migrations. Execute the command to produce a PC/IXF file containing your database's data, then use the IMPORT utility to bring the data into the target DB2 database. Both utilities must synchronize their traverse order for a seamless process.

Exporting Hierarchical Data

When exporting hierarchical data, you must utilize the EXPORT utility command on a typed table hierarchy. For a successful transfer, this hierarchy should be exported using the PC/IXF file format and then moved to the target database with the IMPORT utility, maintaining a consistent traverse order throughout the process.

Post-Export Actions

After exporting data, it's important to commit changes using the COMMIT statement, especially after closing cursors with the WITH HOLD option. If necessary, use the ROLLBACK statement to release all locks. Moreover, utilize the message file to ensure the correct setting of not null values in your exported data.

Example of DB2 Export Command

An example of the DB2 export command is db2 export to staff.ixf of ixf select * from userid.staff. This particular command exports all data from the 'staff' table in the 'userid' schema into an external file named 'staff.ixf' in the PC/IXF format.

Frequently Asked Questions

Can I export a DB2 database to a CSV file?

Yes, the EXPORT command is the best way to get data from a table into a CSV file. It can be run on the server or client and used to export data to any location.

Is it possible to backup and restore a DB2 database without any outage?

Yes, you can use an online backup to take no outage on the source, ensuring the database remains available during the backup process.

Can I use db2 export to move data to another RDBMS?

Yes, you can enable federation and create nicknames in the target RDBMS for moving data, or use CSV export and import as a good option for transferring data to another RDBMS.

What tools can help me to simplify the export and import process in DB2?

Use db2move to make exporting and then importing/loading easier, and db2look to rebuild the database structure.

How can I ensure data consistency when exporting from DB2?

For ongoing data synchronization, consider using HADR, replication methods, or IBM Lift to maintain data consistency.
