Move data from one iSeries server to another

A number of situations occur in enterprise operations that might require moving data from one iSeries™ server to another.

An example for a situation that might require moving data from an iSeries server to another server would be a new dealership opens in a region, and some clients from one or two other dealerships might be transferred to the new dealership as determined by client address. Perhaps a dealership closed or no longer represents Spiffy Corporation sales and service. That dealer's inventories and required service information must be allocated to either the regional office or other area dealerships. Perhaps a dealership has grown to the extent that it needs to upgrade its server, and the entire database must be moved to the new server.

Some alternatives for moving data from one iSeries server to another are:

• User-written application programs
• Interactive SQL (ISQL)
• DB2 Universal Database™ for iSeries Query Management functions
• Copy to and from tape devices
• Copy file commands with DDM
• The network file commands
• iSeries server save and restore commands

• Create a user-written application program
  A program compiled with distributed unit of work (DUW) connection management can connect to a remote database and a local database and FETCH from one to INSERT into the other to move the data.
• Query a database using Interactive SQL
  Using the SQL SELECT statement and Interactive SQL, you can query a database on another iSeries server for data you need to create or update a table on the local server.
• Query remote servers using DB2 Universal Database for iSeries query management function
  The DB2 Universal Database for iSeries query management function provides almost the same support as Interactive SQL for querying a remote server and returning the results in an output file to the local server.
• Copy files to and from tape
  There are several different commands that you can use to copy files to and from tape.
• Move data between iSeries servers using copy file commands
  Another way to move data from one iSeries server to another is to copy the data using the copy file commands with DDM.
• Transfer data over network using Network File commands
  Data can be transferred over networks protocols that support Systems Network Architecture (SNA) distribution services (SNADS). In addition to APPC and APPN protocols used with distributed relational database processing, SNADS can be used with binary synchronous equivalence link (BSCEL) and SNA Upline Facility (SNUF) protocols.
• Move a table using server save and restore commands
  You can move a table from another iSeries server using the Save Object (SAVOBJ) and Restore Object (RSTOBJ) commands. The save commands save database files on tape or in a save file. The save file can be distributed to another server through communications.
