Importing data from a client machine to Amazon RDS for Db2 with the LOAD command - Amazon Relational Database Service

Importing data from a client machine to Amazon RDS for Db2 with the LOAD command

You can use the LOAD CLIENT command to load data from a file on a client machine to the RDS for Db2 server. Because no SSH connectivity exists to the RDS for Db2 server, you can use the LOAD CLIENT command on either your self-managed Db2 server or your Db2 client machine.

Important

The LOAD CLIENT command method is useful for migrating small tables. If your network bandwidth between the client and RDS for Db2 is limited, we recommend that you use a different migration approach. For more information, see the Using native Db2 tools to migrate data from Db2 to Amazon RDS for Db2.

If your data file includes references to large object file names, then the LOAD command won't work because large objects (LOBs) need to reside on the Db2 server. If you try to load LOBs from the client machine to the RDS for Db2 server, you will receive an SQL3025N error. Use the IMPORT command instead.

To load data to the RDS for Db2 server

  1. Log in to your client machine with IBM Db2 Data Management Console. For more information, see Connecting to your Amazon RDS for Db2 DB instance with IBM Db2 Data Management Console.

  2. Catalog the RDS for Db2 database on the client machine.

    1. Catalog the node. In the following example, replace dns_ip_address and port with the DNS name or the IP address and the port number of the self-managed Db2 database.

      db2 catalog tcpip node srcnode REMOTE dns_ip_address server port

    2. Catalog the database. In the following example, replace source_database_name and source_database_alias with the name of the self-managed Db2 database and the alias that you want to use for this database.

      db2 catalog database source_database_name as source_database_alias at node srcnode \
    authentication server_encrypt

  3. Attach to the source database. In the following example, replace source_database_alias, user_id, and user_password with the alias you that created in the previous step and the user ID and password for the self-managed Db2 database. 

    db2look -d source_database_alias -i user_id -w user_password -e -l -a -f -wlm \
    -cor -createdb -printdbcfg -o db2look.sql

  4. Generate the data file by using the EXPORT command on your self-managed Db2 system. In the following example, replace directory with the directory on your client machine where your data file exists. Replace file_name and TABLE_NAME with the name of the data file and the name of the table. 

    db2 "export to /directory/file_name.txt of del modified by coldel\| \
    select * from TPCH.TABLE_NAME"

  5. Connect to your RDS for Db2 database using the master username and master password for your RDS for Db2 DB instance. In the following example, replace rds_database_alias, master_username, and master_password with your own information.

    db2 connect to rds_database_alias user master_username using master_password

  6. Use the LOAD command to load data from a file on the client machine to the remote RDS for Db2 database. For more information, see LOAD command in the IBM Db2 documentation. In the following example, replace directory with the directory on your client machine where your data file exists. Replace file_name and TABLE_NAME with the name of the data file and the name of the table. 

    db2 "LOAD CLIENT from /directory/file_name.txt \
    modified by coldel\| replace into TPCH.TABLE_NAME \
    nonrecoverable without prompting"

  7. Terminate your connection.
