This is very helpful where it just takes too long to take a full backup and in some cases<br />
it is not viable because of the amount of time it takes and because of the impact<br />
backup has to end users, who cannot access the database while it is being backed up.<br />
<strong>DB2</strong> Merge Backup lets you have full backups available at a more consistent and up to<br />
date point in time. <strong>DB2</strong> Merge Backup also gives you the capability to run the merge<br />
processing on a computer outside of your <strong>DB2</strong> database, thus reducing the amount of<br />
resources being consumed on the production computer.<br />
• <strong>DB2</strong> Recovery Expert optimizes recovery processes. It helps organization minimize<br />
recovery times by isolating recovery to just the impacted objects <strong>with</strong>out having to<br />
resort to full database recovery. This means that you can recover faster and <strong>with</strong><br />
greater granularity than what is available <strong>with</strong> traditional database recovery. Think<br />
about the situation where you have multiple tables in a table space. If a user deletes<br />
some data from one of those tables by accident, you can identify which data was<br />
deleted and recover just that data rather than having to recover the whole table space.<br />
<strong>DB2</strong> Recovery Expert log analysis capabilities enables single object recovery as well<br />
as recovery from data corruption caused by flawed applications. This allows database<br />
administrators to quickly restore or correct erroneous data using fewer resources. Log<br />
analysis also lets database administrators monitor activity to sensitive <strong>DB2</strong> tables.<br />
<strong>Data</strong>base administrators can view data changes by date, users, tables, and other<br />
criteria. Administrators may institute tighter controls over the data to ensure that the<br />
data is no longer compromised.<br />
11.2.5 Optimize: InfoSphere Optim Per<strong>for</strong>mance Manager and InfoSphere<br />
Optim <strong>Data</strong> Growth Solutions<br />
Organizations not only want their applications to run, but to run well. While <strong>DB2</strong> provides<br />
advanced self-tuning features, it can only optimize <strong>with</strong>in the constraints of the resources it<br />
has available. Organizations still need to monitor database per<strong>for</strong>mance to detect<br />
per<strong>for</strong>mance erosion that can lead to missed service level agreements and declining staff<br />
productivity. Beyond health monitoring in <strong>Data</strong> <strong>Studio</strong>, InfoSphere Optim Per<strong>for</strong>mance<br />
Manager provides 24 x 7 monitoring and per<strong>for</strong>mance warehousing to give database<br />
administrators and other IT staff the in<strong>for</strong>mation needed to manage per<strong>for</strong>mance<br />
proactively to:<br />
• Prevent problems be<strong>for</strong>e they impact the business<br />
• Save hours of staff time and stress<br />
• Align monitoring objectives <strong>with</strong> business objectives<br />
In addition, when using <strong>Data</strong> <strong>Studio</strong> <strong>for</strong> query development, developers can use the<br />
InfoSphere Optim Per<strong>for</strong>mance Manager integration to see the actual per<strong>for</strong>mance<br />
improvements across iterations of query refinements and executions. Application metadata<br />
such Java packages and source code lines can be shard <strong>with</strong> InfoSphere Optim<br />
Per<strong>for</strong>mance Manager to accelerate problem resolution. Problematic workloads can be<br />
easily transferred to InfoSphere Optim Query Workload Tuner <strong>for</strong> expert recommendations.
