Software Requirement Patterns' title='Software Requirement Patterns' />SAP Business. Objects Enterprise XI3 Deployment Patterns. When deploying an SAP Business. Objects Enterprise system there are a lot of choices for where you can deploy all the services that make up the system. It is then necessary to make sure that you choose the right deployment in order to meet your requirements, for example, is it easily maintained, is it resilient, is it secure, will it support my user base and can it be easily expanded to accomodate additional users. This article looks at different deployment patterns for an SAP Business. Objects Enterprise XI3 system and reviews their advantages and limitations of each. It is the intention then that this can help you make an informed decision about the deployment configuration of your system. The article focuses on the core SAP Business. Objects Enterprise servers and does not include Data Services or Performance Management. Overview of Patterns. The patterns below describe four different deployment configurations where the technologies involved in an SAP Business. Objects Enterprise BOE system are deployment across different numbers of physical servers. Our scenario is a deployment where the users are accessing the system and using Info. View to work with either Crystal Reports, Web Intelligence documents or Voyager applications. The source data for these reporting and analysis tools is held in either a data warehouse or in SAP BW or in some other database or OLAP system. The patterns below include a data warehouse server and an SAP BW server however it is not the intention of the pattern to suggest that both of these are mandatory but it is expected that one or other would be deployed.

Java Design Patterns example tutorial Creational, Structural, Behavioral patterns explained, download pdf, singleton, factory, builder, facade and more. Pattern Overview. This is the most basic deployment where essentially we have all the required server components for a BOE installation on one physical server. These components are,all BOE server components CMS, Web. I Report Server, Crystal Report Server etca Web Application Server IIS, Tomcat etc that hosts the user and admin web applications. A file system to host the BOE repository where documents are held. A database server SQL Server, Oracle, My. Sql etc that hosts the CMS Repository, Audit database and Life.

This server can be running any of the supported operating systems Windows, Unix or Linux. The following diagram is of a basic BOE deployment. Deployment Pattern I Basic Configuration. Xara 1 1 Cd Full With Keygen Crack. Desktop client applications, e. Web Intelligence full client and administration applications such as the Import Wizard will require communication with this server. The ports that BOE uses for communication will need be open on this network. Web based applications will also access the web application server installed on this server and similarly the HTTP port will also need to be opened on this network. Both the database server that BOE is reporting against and the SAP BW server are hosted on a separate physical servers. In the above diagram we are displaying two network branches thick blue lines however this is just to highlight the communication between the different components and a typical installation would normally be on a single LAN. To keep the diagram simple we are displaying all the BOE services as a single component rather than displaying them all individually. Note, some desktop applications, for example universe designer, will require direct access to the data warehouse and SAP BW servers. Sizing. Many factors influence the required sizing for a BOE system and primarily these are the number of users, how the system is being used accessing Web Intelligence documents, Crystal Reports or Voyager applications and how often they access the system. However we can consider a minimum size for this deployment pattern. We can assume that both the web application server and repository database server are in constant use so we should then dedicate a single CPU to each of those. For BOE it is a bit more difficult but 2 CPUs should handle a small deployment. So our physical server should be as a minumum a 4 CPU server. On a 3. 2bit server it is recommended to allocate 2. GB per CPU. The rule of thumb here is that a 3. GB or RAM. Obviously a single CPU can execute more than one process and so this isnt an absolute calculation. For 6. GB limit per process so you can install more RAM if required. Advantages. The obvious advantage is that this deployment is the easiest to install and configure. In addition it is also straightforward to maintain and to backup. Performance is good as we do not have any network latency between the main server components as they are all on the same physical server. Limitations. One disadvantage is that there is no resilience in the system. If one of the components fails or indeed the whole server then there is no backup server to take over. Automatic failover is not always mandatory in a system as it is not always necessary to have the system available 2. AnĀ  alternative is to have a well defined disaster recovery strategy. Another limitation is that although perfromance isnt affected by network latency performance still isnt optimised. We have a single physical server managing several different services the web application server, BOE services, a database service and the OS will spread the load across the available CPUs however it will do this fairly arbitrary and you may find that some key processes will get queued while waiting on another less important process to complete. Here you can then have contention between say the web server, database server and all the BOE services you have running. A further disadvantage is with licensing. There are several different licensing options available from SAP Business. Objects one of which is CPU license where you license the software by the number of CPUs on the server that BOE is installed on. For example if you have a 4 CPU server then you pay 4 times a single CPU license. In the basic pattern weve described here some of the CPU resource on the server will be utilised by the web application server and database server and so the BOE services wont be able to maximise all available CPUs. However the licensing requires that we pay for all CPUs even though we know that the BOE services wont be able to utilise all available CPUs. Note, SAP frequently update and modify their licensing so please check with them for latest licensing information. Pattern II A Distributed SAP Business. Objects Enterprise Deployment. Pattern Overview. Here we start to distribute the components to separate servers in order to improve performance and optimise licensing. This pattern is sometimes described as a 3 tier deployment where we have the components deployed as follows. First Tier Web Application Server. A Web Application Server that hosts the Info. View and the CMC web applications or a custom web application. Second Tier BOE Application server. BOE services are deployed onto a separate physical server and this server will also hosts the file system that for the BOE file repository essentially where all the Web Intelligence documents, Crystal Reports, universes and any other file based objects are held. BOE Repository Database server. Here we have moved the BOE repository and audit databases onto thier own dedicated server. It is not recommended to have the BOE repository database on the same server as the data warehouse or the database system that you are reporting against.
