Getting Started with IBM Data Studio for DB2

InfoSphere Optim Query Workload Tuner can provide either single query analysis and
advice , but can take as input an entire SQL workload (such as all SQL used in an order
processing application) as input, which enables database administrators to determine for
example what indexes or what statistics might provide the most benefit for the overall
performance of the workload.
11.2.4 Deploy and Operate: Data Studio, InfoSphere Optim Configuration
Manager, and DB2 Advanced Recovery Solution
Managing availability is often job number one for database administrators. When your
database goes down and the data is unavailable to the end users, it can look bad for you
and your organization. If you’re supporting a business, that can have a direct impact on the
bottom line.
Data Studio, as you have learned in this book, provides all the basic database
administration capabilities required for managing a DB2 deployment. However, when
managing many deployments, more capability is desirable to manage, synchronize, and
govern configuration across hundreds of databases.
InfoSphere Optim Configuration Manager discovers databases, clients, and their
relationships and tracks configuration changes across them. It assists with application
upgrades to determine that all clients have been changed correctly, and lets organizations
quickly visualize and report on inventory and configuration changes. Such changes can
also be correlated to performance degradation via contextual links in InfoSphere Optim
Performance Manager, see section 11.2.5 for more information.
DB2 Advanced Recovery Solution is focused on reducing time to recover by aligning
backup strategies with outage related Service Level Agreements providing faster methods
to recovery and is comprised of the following:
• InfoSphere Optim High Performance Unload provides a high-speed unload utility as
an alternative to the DB2 export feature. This product significantly reduces the time
required to migrate databases, manage within batch windows, capture data for test
environments, and move data without impacting production systems.
Because unloads are so fast, you can use this as a means for migration, moving large
amounts of data from one system to another or for backup.
The product is fast because it can o go directly to the data files, bypassing the
database manager altogether. The tool does not interfere with or slow down production
databases or impact CPU resources as it is completely outside of the database. It can
also perform unloads from multiple database partitions, and it provides repartitioning
capability in a single step for rapid data redistribution on the same or different system.
This is particularly useful in warehouse environments where repartitioning can be very
much a manual process.
• DB2 Merge Backup lets you avoid full database backups by merging incremental and
delta backups into a full backup. Thus, it reduces resource requirements to maintain a
full backup for large databases and it shortens recovery times on production servers
ensuring full backups are always available when needed.
