    Zero Cost Cloud Migration CLOUD-FIRST is a captivating concept around which the emerging businesses are predominantly dependent upon. While it aligns with the digital transformation strategies built for enterprises, migrating workloads to cloud comes with its own challenges like flexibility, application performance and budgets. more details visit Zero cost cloud Migration services In a data-driven world, you need a comprehensive business model to accelerate your IT transformation with cloud services and offering you the advantages of a cloud. Suneratech improves your business agility, security, cost-efficiency, and simplicity, with a 4-step strategy to move you to cloud while reaping the benefits. ZCCM Advantage for Customers When a customer withdraws from other service providers like IBM or OMCS, and opt for a new provider, a customer must pay for both the providers until the migration is completed. ZCCM program is a great choice for such customers, as it saves this double cost by paying all the Oracle costs until the customer's contract terminates with other cloud service providers. Suneratech migrates all workloads in scope to Oracle Cloud Infrastructure (OCI), at ZERO Cost, and will not invoice until all workloads are successfully migrated to Cloud.

  • In this release, Oracle Automatic Storage Management is extended to support a general-purpose cluster file system to help customers reduce their storage management costs.
  • ...1 more annotation...
  • The combination of Oracle Database 11g Release 2 Advanced Compression and Partitioning support the reduction of storage costs by compressing data as much as 2-4x and simplifying use of lower cost storage tiers.

Oracle ASSM Performance - 0 views

  • Cons of ASSM: §         Slow for full-table scans: Several studies have shown that large-table full-table scans (FTS) will run longer with ASSM than standard bitmaps. ASSM FTS tablespaces are consistently slower than freelist FTS operations. This implies that ASSM may not be appropriate for decision support systems and warehouse applications unless partitioning is used with Oracle Parallel Query. §        Slower for high-volume concurrent inserts: Numerous experts have conducted studies that show that tables with high volume bulk loads perform faster with traditional multiple freelists. §         ASSM will influence index clustering: For row ordered tables, ASSM can adversely affect the clustering_factor for indexes. Bitmap freelists are less likely to place adjacent tows on physically adjacent data blocks, and this can lower the clustering_factor and the cost-based optimizer's propensity to favor an index range scan.
  • Pros of ASSM: §          Varying row sizes: ASSM is better than a static pctused. The bitmaps make ASSM tablespaces better at handling rows with wide variations in row length. §         Reducing buffer busy waits: ASSM will remove buffer busy waits better than using multiple freelists. When a table has multiple freelists, all purges must be parallelized to reload the freelists evenly, and ASSM has no such limitation. §         Great for Real Application Clusters: The bitmap freelists remove the need to define multiple freelists groups for RAC and provide overall improved freelist management over traditional freelists.
