OLAP_MAX_CONNECTIONS Property Considerations
By Keith Rosenthal-Oracle on Jul 07, 2014
The OLAP_MAX_CONNECTIONS property controls the maximum number of connections from Planning to Essbase. The default setting is 10, but the property can be increased to allow for more concurrent Essbase connections. The Hyperion Planning Administrator’s Guide recommends a setting of 20 for 100 users and 100 for 500 users.
Although the OLAP_MAX_CONNECTIONS property can be increased, the amount the setting can be increased is constrained by the SERVERTHREADS setting in Essbase. The SERVERTHREADS setting defines the number of threads available for an Essbase application. The default SERVERTHREADS setting is 20, so if this setting is not changed, the most the OLAP_MAX_CONNECTIONS can be increased is 20. Therefore, if an OLAP_MAX_CONNECTIONS setting higher than 20 is required, the SERVERTHREADS setting in Essbase must also be increased to a value at least equal to the OLAP_MAX_CONNECTIONS setting. If the application requires direct connections to Essbase using SmartView or Financial Reports that bypass Planning altogether, then the SERVERTHREADS setting should be set to a value higher than the OLAP_MAX_CONNECTIONS setting based on the required number of concurrent SmartView and Financial Reports Essbase connections.
