Time Zones<\/a><\/p>\nOne of these parameters that is present on all adaptors, is the Adaptor Pool Size<\/strong> parameter.<\/p>\nAbout Adaptor Pools<\/h3>\n
The Adaptor Pool Size<\/em> allows you to specify the minimum and maximum number of instances of this type of adaptor that will be available in memory in IFS OI Server. This is related to the number of simultaneous connections available to that data source.\u00a0 It\u2019s important to note that this setting is for this<\/strong><\/em> configuration of the adaptor.\u00a0 If you configure two PI adaptors, there will be 2 adaptor pools, one for each of them.<\/p>\nThe minimum<\/strong> is important because it does take an amount of memory to store each of these adaptor instances.\u00a0 So if the minimum value is high, for all adaptors, then it will consume more RAM on the web server.\u00a0<\/p>\nThe maximum<\/strong> is important because when the load on the server increases, we can load up more instances of the adaptor and run the requests for data in parallel, which gives us more speed.\u00a0 But, at the same time, we don\u2019t want to overload the data source, so we provide this upper limit.<\/p>\nWhen IFS OI Server detects that the adaptors in the pool are not being used, it reduces the number of adaptors in the pool back down to the minimum to save memory.\u00a0 So, something to consider is that it will take small amount of time when a new instance of the adaptor gets created in memory and added to the pool. If you set your limit too low and you get a lot of simultaneous requests from this one data source, there will be a small lag as each new adaptor gets added to the pool.<\/p>\n
So there is a balancing act here between memory use on the web server, performance of gathering data, and not putting too much load on the source system.<\/p>\n

Identifying external systems<\/h2>\n
One of the more advanced, but very useful, features of a tabular datasource in IFS OI Server is a concept known as a System Identifier<\/em>. \u00a0This enables IFS OI Server to translate an entity name in IFS OI Server, to the equivalent name in each of the source systems. \u00a0<\/p>\nLet's take an example. \u00a0We have an entity in IFS OI Server, called Well_1<\/strong>. \u00a0This same well may be known as W1<\/strong> in IFS OI Production and Well1<\/strong> in Qbyte. \u00a0Now these are different names, so how can we tie these all back together? \u00a0In IFS OI Server we can create a mapping between an entity, and an equivalent name in each datasource (so we can have one mapping for each datasource).<\/p>\nSo how does it work? \u00a0When you request data for Well_1, from the IFS OI Production datasource, IFS OI Server will substitute the entity name Well_1<\/strong> with\u00a0W1<\/strong> in the SQL statement being executed in the dataset. \u00a0When the data is returned, IFS OI Server automatically adds an extra column to the returned data, with the original entity name included, completing the conversion in both directions.<\/p>\n\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"
An Adaptor is a component of IFS OI Server that enables communication with external data systems through a configured datasource. This article describes what adaptors and datasources are and how they are used.<\/p>\n
