Oracle Database Monitoring with eG Enterprise

Proactive Monitoring and Optimization of Oracle Database Servers

In many infrastructures, a database server (or a cluster) supports multiple front-end servers. Consequently, when there is a performance bottleneck or failure of a database server, it impacts the performance of several services that rely on it. Effective database management requires a great deal of expertise, and Oracle monitoring tools are critical for successful IT service delivery. eG Enterprise helps you ensure top database performance by ensuring that:

• Queries that are long-running, I/O intensive and memory intensive are identified and optimized for fast application performance
• Unusual locking behavior of queries is identified, and necessary query modifications performed
• Servers have enough buffers to perform and sort operations in memory rather than on disk
• Database workload is evenly distributed across the different datafiles
• Query waits are identified and the database subsystem tuned to minimize wait times

• Troubleshoot Slow Database Queries with Detailed Analytics

  

  • Quantify overall database server workload. Monitor commits and rollbacks happening
  • Identify top queries by I/O activities, CPU usage, memory usage
  • Identify which queries are executing for a long time, highlight username, application, and query
  • Identify if any application is leaking cursors (e.g., due to ResultSets not being closed)
  • Identify the largest tables in the database server

• Get Comprehensive Insights into Oracle Database Server Performance

  

  • Monitor space usage by tablespace; determine when a tablespace is likely to run out of space
  • Monitor the rollback segments. Track writes, waits, and gets to each segment and determine if additional rollback segments are necessary (e.g., waits > 5%)
  • Track activity of each of the data files. Identify if the I/O activity is not balanced across all data files and if additional data files are required to balance the I/O activity
  • Track system and session waits by type; identify how the database server can be used to minimize wait time
  • Monitor fragmentation level of database tables and indexes, and be proactively alerted to situations when online/offline tuning of the database is required

• Audit Accesses to the Oracle Database Server

  

  • Track the session workload to the database server overall and identify sessions killed, sniped or in blocked mode
  • Monitor sessions by users and identify if specific user sessions are causing query blocking
  • Report on root-blockers - i.e., queries blocking other queries
  • Identify which application/user is imposing the most load on the database server. Track if there is a database connection leak that is leaving orphaned connections to the database server
  • Report on top queries to the database server by application/client, categorized by CPU, memory, and I/O time used
  • Track any and all configuration changes on the Oracle database server; correlate performance changes with configuration changes made

  • Support is available on Microsoft Windows and Linux platforms.
  • Choose between agent-based and agentless monitoring.

   

• Monitor Database Server Health

  

  Track the key parameters that can affect database server performance:

  • Does the server have sufficient CPU, memory, and disk resources?
  • Is one of the disk drives seeing more I/O than others?
  • Is there excessive disk queueing that can affect response times?
  • Is the disk heavily fragmented and is defragmentation required?
  • Are there any I/O errors during disk access that may indicate a faulty disk that is affecting database access?
  • Get complete details of the wait events to figure out which process initiated the even

  What Oracle Database Monitoring with eG Enterprise Reveals

  Database service monitoring		Is the Oracle database server available for servicing requests and what is the response time for a typical request?
  Session monitoring		How many users are accessing the Oracle database currently? Who are the active users?
  Query monitoring		What are the current top 10 SQL queries in terms of resource utilization?
  Transaction monitoring		What is the commit and rollback behavior of the applications using the Oracle database?
  Alert log monitoring		Have there been any recent errors/events in the Oracle alert log? What are they?
  Rollback segment monitoring		Is there heavy contention for the rollback segments?
  Lock and latch monitoring		Is there contention for locks? Is a specific application holding a lock for a long time? Which lock(s) are these?
  Cache monitoring		Are the library cache, dictionary cache, and the data buffer cache adequately sized?
  Full table scan monitoring		Is there any full table scan happening on the Oracle database server? If so, how frequently?
  Tablespace monitoring		Are any of the tablespaces reaching their storage capacity? Is the load adequately balanced across the tablespaces?
  Hot file monitoring		Is the disk I/O (read/write) being balanced across the datafiles or is there a particular hot datafile that is handling all the requests?
  Redo log monitoring		Is the Oracle redo-log buffer sufficiently sized, or is there a large number of requests waiting for redo log space?
  Object monitoring		Is there any invalid object in the database? Which ones? Which objects have been recently modified and when? Are there objects that have reached their maximum extent? Which ones are these?

• Monitor Oracle Database Server Performance from an Application Perspective

  

  eG Enterprise allows database performance to be monitored in the context of the applications using the database server.

  • Without requiring any agents on the database servers, eG Enterprise APM traces all application accesses and reports on slow queries and exceptions during database processing.
  • When a specific web page or URL is slow, you don't have to wonder any more as to what is causing the slowdown. eG Enterprise APM gives you the answers at your fingertips.

  This eliminates finger-pointing between application development, application operations, and database admin teams.
