Performance

There are some guidelines that you can follow to improve the performance of your copy operations.

Apart from the guidelines discussed in the proceeding topics, when you copy distributed files, you should be familiar with the various factors that affect the performance of the copy command. The DB2^® Multisystem feature provides support for distributed files, or files that are spread across multiple iSeries™ servers. When you copy distributed files, you should be familiar with the various factors that affect the performance of the copy command. You should be aware of restrictions that apply when you copy to and from distributed files. For information about copying distributed files, see DB2 Multisystem .

• Avoid keyed sequence access paths
  A copy that requires maintenance of a keyed sequence access path is slower than a copy from or to an arrival sequence access path.
• Specify fewer parameters
  In general, you can improve copy performance if you specify fewer optional copy parameters.
• Check record format level identifiers
  You can also improve copy performance by correctly setting the record format level identifiers in the CPYF command.
• Prevent errors when copying files
  You can prevent many copy errors when you plan for certain conditions and situations ahead of time.
