If not, you would need to license PVUs for any hot primary servers that are licensed under the PVU metric, plus you would need to acquire additional licenses for the remaining DB2 servers that are licensed under any other metric.
For this reason, it makes sense to try to license all of your DB2 Workgroup primary servers under the same licensing metric to help minimize the licensing cost of your warm standby servers. As with DB2 Express, this license metric is best suited for environments where you can identify and purchase sufficient AUSI entitlements for the individuals who will connect to each DB2 Workgroup server in advance, and prevent unauthorized, unlicensed people from accessing those same servers.
Also, like DB2 Express, you must acquire a minimum of 5 AUSI licenses per server or virtualization session in which a copy of DB2 Workgroup is installed, although multiple copies installed in the same virtualization session are treated as one installation from a licensing perspective. For example, if you have two copies of DB2 Workgroup installed and running in the same core partition and want the same 7 people to be able to connect to either server, you would need to acquire only 7 AUSI licenses.
In addition to the core limit, you are also restricted to no more than 4 processor sockets. However, if your physical server is greater than 16 cores, you would first need to partition the server to ensure that each copy of DB2 Workgroup is restricted to 16 cores.
After you introduce virtualization into the equation, things can get complicated when you try to figure out how many LU Socket licenses you must purchase, based on the number of virtual cores that will be used by DB2 Workgroup. Use the following simple counting rule to help you to calculate the required LU Socket entitlements in almost any scenario: 1.
For each physical server or, where partitioned, virtualized session that will have a copy of DB2 Workgroup installed, sum the number of processor cores that are available to that server. Sum the results of step 1 for all virtual servers on a single physical server. Divide the result of step 2 by the number of processor cores per socket on the physical server.
Round up the result of step 3 to the nearest whole number. The lesser of the result of step 4 and the number of active sockets on the physical server is the required Limited Use Socket entitlement. Therefore, you would need to buy 3 LU Socket licenses in total for this particular environment. The great thing about LU Socket licensing is that you pay the same price per socket regardless of how many cores are on the socket.
Keep in mind, however, that you cannot exceed the core limit. LU Socket licensing delivers the best value when used with high- end processors that have many cores per socket. Like PVU, LU Socket licensing also allows an unlimited number of users to connect to a DB2 Workgroup server, which makes it an ideal choice for customer-facing applications.
If primary servers are licensed under the LU Socket metric, one or more warm standby servers can be had for the price of a single LU Socket license per physical server. Changes from DB2 Workgroup Each database cannot contain more than 15 TB of user data, as reported by the script that is provided with the software. Perhaps the biggest change from DB2 DB2 Workgroup can play many roles in a business. It is very well suited for small- to medium- sized businesses that need a full-fledged scalable and available relational database store, but wouldn't benefit from more than GB of memory or more than 16 cores of processing power.
Perhaps more than DB2 Express, DB2 Workgroup is especially well suited for enterprise environments that need small servers for line of business applications, or for departments that need enterprise services for lower transactional throughput applications.
However, like DB2 Express, this edition is not well suited for applications that require analytic features such as aggregates or MDC tables, because these features are not part of the base DB2 Workgroup server. The company delivers its products nationwide to around 12, local pharmacies, generating up to 40, sales invoices every year.
The extreme scalability and exceptional performance of DB2 Workgroup enables them to support increasing data volumes as their business grows. At the same time, they expect to reduce their overall storage and administration costs by around 50 percent. Did you get that?
DB2 Workgroup Edition does more work and saves money at the same time. Now even the procurement folks think that DB2 is cool! DB2 Enterprise Server Edition DB2 Enterprise is meant for large and mid-sized departmental servers and is rich in base features and services. For example, query performance-boosting services such as intraquery parallelism technology that breaks a single query into parts that are then executed in parallel , MDC tables technology that enables data to be clustered according to multiple column attributes for faster retrieval and easier maintenance , materialized query tables MQTs, which are like views whose results are ready for retrieval or for use in other queries are all provided at no additional charge in this DB2 edition and are not available in DB2 Express or DB2 Workgroup.
For example, suppose that you have a large table containing retail sales data. Data for the current quarter is inserted and updated frequently, and those transactions need to happen quickly, whereas older data is not accessed very often, and when it is acceptable for response time to be longer, processing can be delayed.
With DB2's multi-temperature storage management, you can tell DB2 to put the data from the current quarter on fast SSD storage and everything else on slower disk storage. DB2 will do this in a way that is completely automatic and transparent to your applications. There are no limits with respect to the amount of RAM that you can leverage with this DB2 edition; in fact, one benchmark result from our labs was obtained by using almost 4 TB of memory for the buffer pools; that's more RAM than the total data volumes that are owned by many companies.
There is also no maximum PVU rating for the underlying server or virtualization session where the DB2 Enterprise software is running. The combination of no resource limits with high performance for both transactional and analytic workloads makes DB2 Enterprise a great choice for even the most demanding single server OLTP and mixed workloads. Different platforms and virtualization technologies have different prerequisites that enable you to use this DB2 edition in a subcapacity environment.
As with DB2 Express, this license metric is best suited for environments where you can identify and purchase sufficient AUSI entitlements in advance for the individuals that will connect to each DB2 Enterprise server. For every installation, there is a break-even point at which it makes more sense to license the server through the PVU metric. Consider another example. Changes from DB2 Enterprise These features are no longer available as separately purchasable add-ons to DB2 Enterprise.
Both tools make it easier to take advantage of DB2 Enterprise's built-in analytic capabilities described earlier. DB2 Enterprise should be strongly considered for any applications that require limitless flexibility for example, the use of table partitioning and scalability there are no PVU or RAM limits.
Because there are no limits, there really are no capacity planning considerations with DB2 Enterprise. That said, if you want to run a cluster of servers for extreme scalability, or if you have warehouse workloads that execute against massive amounts of data, or if you wish to leverage advanced features and tools like data compression, workload management, the groundbreaking BLU Acceleration innovations, IBM InfoSphere Optim productivity tools, and so on, then you should consider the DB2 Advanced Editions that are described later in this article.
The museum is a symbol of traditional China, as well as the largest and best-preserved masterpiece of classical Chinese architecture.
The Palace Museum recently implemented a first-of-a-kind, fully immersive, three-dimensional 3D virtual world that recreates a visceral sense of space and time in The Forbidden City. This internet-based experience, which represents the city as it was centuries ago during the height of the Ming and Qing dynasties, supports thousands of concurrent users with scalability comparable to that of massive multi-player games. These links take you to the most up-to- date platform support information.
DB2 Advanced Workgroup is meant for mid-size departmental deployments that require the most sophisticated features available in DB2; that is, any OLTP, warehouse, or mixed workloads that don't require more than 16 processor cores, GB of memory or, alternatively, 4 processor sockets; more on that below , and 15 TB of user data per database.
However, don't be misled by the "departmental" designation. DB2 Advanced Workgroup is fully stacked with all the high value data management capabilities you could ever possibly want, including everything that comes in DB2 Enterprise, plus BLU Acceleration column-organized.
Database partitioning Database partitioning, a capability that is inherited from InfoSphere Warehouse, enables table data to be spread out across multiple servers according to a defined distribution key. Complex analytical queries are transparently broken down by DB2 into subqueries that can be processed in parallel. For very large data stores, database partitioning provides a way to get great query performance by scaling out across multiple logical partitions or physical partitions.
However, unlike database partitioning, DB2 pureScale is designed to provide availability and scalability for OLTP workloads, and to meet the most demanding transaction processing needs, both now and in the future. Breakthrough levels of availability are ensured, thanks to uninterrupted processing during node failures, redundant architecture, and integration with DB2's HADR capability, starting with DB2 Adding capacity is painless because DB2 pureScale does not require application changes.
If there is one thing to know about DB2 pureScale, it is that it provides transparent application scaling. Although this term is a competitor's favorite, it is just marketing. This means that you don't have to build locality of data information into your applications. In addition, there are all sorts of amazing engineering techniques that provide the fastest failure detection and recovery times that we have ever seen in distributed computing environments, as well as near-linear scalability.
It is outside the scope of this article to delve into what DB2 pureScale looks like and how it works. Figure 3 shows an architectural overview of a DB2 pureScale environment. As you can see, a DB2 pureScale environment is made up of multiple data servers. A cluster caching facility CF provides central control services for a global buffer pool, lock management, and interested page lists. Clients connect to members in a DB2 pureScale cluster, and these members interact with the CF to help process client applications.
DB2 compression services DB2 compression services optimize the performance of your database while minimizing the footprint of your data. By using intelligent compression algorithms and techniques to shrink the size of data that is located in tables including temporary tables , indexes, and more, DB2 is able to maximize compression rates and maintain those rates across time while also reducing memory usage. But there is more. Consider for a moment the other implicit benefits that arise from compression.
Trust us, it extends beyond disk savings. Think about all those backup images that you are mandated to keep. Not only will they be smaller, the backup operations themselves will run faster because you are backing up fewer data pages. Consider for a moment that if data is compressed on disk and in the memory buffers, you will be able to get more data into those heaps. Finally, consider the environment charge back for your storage; not only will it save you money, it'll reduce the ecological footprint of your IT solution.
The point here is that compressing your data is more than just saving disk space; it is environmentally friendly too! For example, let's assume that you have a mixed workload database that is used mainly for transactional purposes but will occasionally need to process long-running warehouse-type queries.
Suppose, moreover, that you want to ensure that those long-running queries don't ever slow down the overall database system. With workload management, you can establish policies that will prevent the long-running queries from impacting transactional processing. When combined with workload management, multi-temperature storage management becomes even more powerful, because it enables you to also prioritize workloads according to the.
As a result, even if you don't have different storage types, workload management will still give priority to the execution of workloads that impact hot data.
Replication technologies Homogeneous Q replication and change data capture CDC are both replication technologies that provide greater throughput and can handle larger transaction volumes than homogeneous SQL replication. Homogeneous Q replication, in particular, can achieve throughputs in excess of 50, transactions per second with subsecond latencies, even with miles between source and target.
With DB2 Advanced Workgroup edition, you can use either of these capabilities to replicate from a single DB2 source data server to up to two DB2 target data servers. These capabilities and tools are included in the following list:. Moreover, you can use DB2 Advanced Workgroup for strictly transactional workloads, strictly warehouse workloads, or anything in between.
If you want the ultimate in deployment flexibility and can live with the resource restrictions, DB2 Advanced Workgroup is a superb choice. These limits must be observed regardless of how many installations or DB2 Advanced Workgroup instances created by using the db2icrt command , you have running on a particular server or virtualization session. Alternatively, if you are eligible to license DB2 Advanced Workgroup by TB as explained below , you could install the software on this unpartitioned server because it meets the 4-processor socket criteria.
Regardless of how you license DB2 Advanced Workgroup, you are limited to 15 TB of user data per database, as reported by the script that is provided with the software.
You must purchase the total number of PVUs that are associated with the server or virtualization session where the DB2 Advanced Workgroup software is installed. When licensed by PVU, DB2 Advanced Workgroup is not allowed to use more than 16 cores per server or virtualization session, so be sure to limit the number of cores that DB2 can access to no more than 16 so that you don't end up paying for cores that won't be used. Keep in mind that different platforms and virtualization technologies have different prerequisites that allow you to use this DB2 edition in a subcapacity environment.
In addition, if you are licensing DB2 Advanced Workgroup as a warm standby for example, in an HADR configuration , you need to license it for only PVUs per physical standby server, or in the case of a DB2 pureScale or database partitioning warm standby cluster, PVUs across all machines in that cluster. As with DB2 Enterprise, this license metric is best suited for environments where you can identify and purchase sufficient AUSI entitlements for the individuals who will connect to each DB2 Advanced Workgroup server.
You must also calculate the required TB licenses on a per database basis. Unlike the PVU or AUSI option, there are no memory or core limits associated with the TB license metric, although you are restricted to a maximum of 4 processor sockets. This license metric is intended for use with predominantly warehouse workloads. In the latter case, the majority of your workloads must access those tables when a DB2 Advanced Workgroup server is licensed by the TB metric.
For column-organized tables, OPM has additional table space and workload management metrics in its reporting capabilities to help you monitor their use. Even without HADR, it is possible to set up a standby environment by using alternate technologies such as the homogeneous Q replication capability that is included with the DB2 Advanced editions.
In that case, you would be required to license 1 TB per database on a warm standby. The aforementioned core and memory limits also apply to the entire cluster. Two of these servers are configured to perform the role of a CF, leaving three other servers to act as data members. You would be allowed to use DB2 Advanced Workgroup in this environment, because it falls within the total 16 cores per cluster requirement for PVU.
The CF servers don't have to sit on a separate server; they can reside within a virtualization session that is colocated on the same server as a DB2 member running in a separate virtualization session. DB2 Advanced Workgroup is ideal if you want to have all the very best DB2 capabilities and tools at your disposal. If you need unlimited scalability or have massive databases exceeding the 15 TB limit, we strongly recommend that you look at DB2 Advanced Enterprise Edition described below instead.
If you are currently running DB2 Workgroup 9. Inclusion of the 9. The real deal! DB2 Advanced Enterprise is designed for mid-sized to very large enterprise servers and is packed with all of the same great features and tools that come with DB2 Advanced Workgroup Edition, but without any resource limitations whatsoever.
If you need unrestricted ability to scale in, scale out, add memory, or store unlimited amounts of data, this is the recommended DB2 edition for you. Whatever the workload, whatever the need - from plus-node DB2 pureScale clusters to petabyte data warehouses - DB2 Advanced Enterprise is up to the task. This capability enables you to access and integrate diverse data and content sources across your entire enterprise into a single, virtual, consolidated view to support your key business decisions and processes.
This will allow an unlimited number of users and devices to access the DB2 Advanced Enterprise server. Different platforms and virtualization technologies have different prerequisites that allow you to use this DB2 edition in a subcapacity environment. As with DB2 Advanced Workgroup, this license metric is best suited for environments where you can identify and purchase sufficient AUSI entitlements for the individuals who will connect to each DB2 Advanced Enterprise server. And as with DB2 Advanced Workgroup, you need.
In the latter case, the majority of your workloads must access those tables when a DB2 Advanced Enterprise server is licensed by the TB metric. Changes from DB2 Advanced Enterprise Alternatively, if you wanted database software that was optimized for warehouse workloads, one of the InfoSphere Warehouse editions would have been appropriate instead.
All of that changes with DB2 Advanced Enterprise The TB pricing metric, which might be appropriate for your warehouse and analytic workloads, is also new for version Choosing this metric enables you to add more CPU power to your long-running queries without having to incur additional costs, which would be the case under the PVU metric.
Finally, DB2 Advanced Enterprise These are unrestricted supporting programs, which means that they can be deployed instead of or in conjunction with DB2 Advanced Enterprise DB2 Advanced Enterprise should be strongly considered for any applications that require limitless flexibility, scalability, compression, security, and advanced database management tools.
