Application Notes - Maximizing Efficiency Through Data Replication Manager Data Movement 13
Data Mining
Organizations accumulate large and growing amounts of data in various formats and in different
databases. Data Mining is the process of moving or copying this raw data to a location where it can be
examined and processed by analytical tools to produce useful and understandable patterns of
information. Correlations or patterns can be discovered within numerous fields in large relational
databases. Once the data is available to analytical software tools, processing can occur offline to
eliminate computational resource drains to an ongoing business.
The ways to make copies of your data available at another location are the same as those for Data
Distribution. If you are working in a disaster-tolerant environment like DRM, use the procedure
“Disaster Tolerant Data Movement to an Alternate Site” on page 20. If your data resides outside a
disaster-tolerant environment, use the procedure “Non-Disaster Tolerant Data Movement to an
Alternate Site” on page 29.
Procedures and Examples
This section demonstrates how to perform the various procedures that were mentioned in the sections
of Data Backup, Data Distribution, Data Migration, and Data Mining. An illustration of the procedural
steps is presented, and is followed by an example using the required CLI commands. Table 2 lists the
procedures and specifies the topics to which they apply.
Some procedures are described as “disaster tolerant.” This means that the procedure uses the features
of DRM with an initiator and target site using remote copy sets. Non-disaster tolerant procedures do
not use the pre-existing remote copy set feature of DRM.
NOTE: To distinguish between procedures performed at the initiator or target sites, symbols are used at each step
for reference. The I symbol identifies a step performed at the initiator site and a T symbol identifies a target-site
step.
