Key learnings from peers

Valuable Features

Oracle Coherence's most valuable features include distributed processing, scalability, high availability, and data affinity. Users appreciate support for query and aggregation, entry processors, POF serialization, and real-time data processing. Clustering and cache management, with capabilities like read-through, write-through, and near cache strategies, are also highlighted. Coherence efficiently manages data with parallel processing and load balancing. Multi-indexing, event-driven architecture, and integration with other technologies are key advantages.
  • "Coherence is beneficial due to its multi-indexing to the same object and filtering based on data attributes within the object, followed by aggregation."
  • "Technical support from Oracle is okay."

Room for Improvement

Oracle Coherence requires improved cluster configuration tools to prevent management complexities and failures. Users find its configuration overly complex, with XML-based settings posing challenges. Monitoring needs enhancements, including user-friendly interfaces and better documentation. The API is seen as lacking modern features compared to alternatives. Security and performance concerns are mentioned, coupled with the desire for easier integration and better cross-regional data transfer capabilities. Users also seek improved error handling and reduced setup complexity.
  • "The initial setup is complex and time-consuming."
  • "This platform has issues with stability and performance."

Pricing

Oracle Coherence is frequently viewed as expensive, with many users exploring cheaper alternatives, particularly open-source options offering basic features. Pricing is perceived as high due to a licensing model based on CPU count or servers, affecting cloud deployments. Suitable for high-end requirements where advanced features are necessary, Coherence can justify its cost despite being costly compared to competitors. Organizations recommend procuring fast, memory-rich hardware to optimize costs, but small businesses might find it less viable.

Service and Support

Customers describe Oracle Coherence support as mixed, frequently rating it medium, with experiences ranging from prompt and competent to lacking. Many find resolution dependent on escalating issues or their support agreement level. Some highlight the importance of platinum or gold plans for timely assistance. Several stress the need for internal diagnostic efforts before engaging support. Opinions on technical assistance vary widely, from essential and excellent to unsatisfactory, often influenced by individual interactions and support tiers.

Deployment

Users found Oracle Coherence's initial setup varied in complexity. Many noted ease in local setup but faced challenges with cluster configurations and tuning. Documentation was extensive but not always clear, leading some to contract experts. Some users encountered a straightforward experience aided by tutorials, while others struggled with XML and integration tasks. Complexities included PofSerializer issues, WebLogic differences, and a steep learning curve despite initial ease. The setup often required custom configurations and code adjustments.

Scalability

Many users have not faced issues with scalability in Oracle Coherence, praising its ability to scale horizontally and vertically. Some reported problems with large messages or during node expansion, citing node crashes and concerns about chatter. Licensing costs and record versioning were noted as potential scalability challenges. Others have successfully scaled clusters across sites or used multiple instances without issues. Coherence is valued for its data distribution and replication capabilities, crucial for enterprise demands.

Stability

Many report stability issues with Oracle Coherence, experiencing node failures, timeouts, and bugs, often due to configuration errors or network problems. Some have not faced stability problems and praise its fault tolerance. While a few experience annual disruptions, others appreciate its maturity and find it reliable compared to other tools. Certain users require significant maintenance planning. Disturbances include cluster failures due to master-slave confusion and server exclusion. Some encounter minor and infrequent serious glitches.
