Information on Data Sources¶
The following MBeans provide information about the data sources defined on the Server:
GlobalDataSourceManagementInfo: provides information about all the data sources of the Server. See section GlobalDataSourceManagementInfo MBean.
LocalDataSourceManagementInfo: provides information about all the data sources of a specific database. See section LocalDataSourceManagementInfo MBean.
DataSourceManagementInfo: provides information about a specific data source. See section DataSourceManagementInfo MBean.
GlobalDataSourceManagementInfo MBean aggregates information about the
number of data sources on the Virtual DataPort Server and how many active
requests they are processing. This MBean is located at
Attributes of the GlobalDataSourceManagementInfo MBean¶
GlobalDataSourceManagementInfo MBean has these attributes:
TotalDataSourceCount: number of data sources of any type on the Virtual DataPort Server.
TotalActiveRequestCount: number of current requests to any data source on the Virtual DataPort Server.
- For every type of data source there is an attribute with the number of data sources and the number of active requests to that type of source.
ITPMaintenanceDataSourceCount: number of Web (WWW) sources that have the maintenance option enabled.
ITPMaintenanceActiveRequestsCount: number of current requests to Web sources that have the maintenance option enabled.
Each Virtual DataPort database has a
which has the same attributes as
GlobalDataSourceManagementInfo, but only
considers the data sources that belong to that database. This MBean is located at
DataSourceManagementInfo > database name.
Each data source has its own MBean in
DataSourceManagementInfo > database name > data source type > data source name.
It provides information about the number of requests to that specific data source, about
its pool of connections and about the last ping invocation.
Attributes of the DataSourceManagementInfo MBean¶
DataSourceManagementInfo MBean has the following attributes:
DatabaseName: name of the data source database.
DataSourceName: name of the data source.
DataSourceType: type of the data source, which can take one of the following values:
CUSTOM. Note that internally, Excel files are actually
ESSBASE(Oracle Essbase Multidimensional DB)
ITP(Web - ITPilot)
OLAP(OLAP multidimensional DB)
SAPBWBAPI(SAP BI 7.x BAPI and SAP BW 3.x BAPI Multidimensional DB)
WS(SOAP Web services)
NumRequests: Number of requests made on the data source since the start of the Server.
ActiveRequests: Number of active requests to the data source.
NumIdle(only for JDBC and ODBC sources). Provide information about the pool of connections with the source:
MaxActive: maximum number of connections in the pool.
NumActive: number of connections established with the source that are being used to execute a query.
NumIdle: number of idle connections established with the source.
isMaintenanceEnabled(only for ITPilot - Web sources):
trueif the maintenance option is enabled.
PingDownCause(only for JDBC, ODBC, LDAP, OLAP, SAPBWBAPI, SAPERP and SALESFORCE sources). Provide information about the last ping invocation to the data source, both from the stored procedure PING_DATA_SOURCE or the
ping()operation of this MBean explained below:
PingStatus: result of the last ping invocation, which can take the value
PingExecutionTime: instant when the last ping to the data source actually started.
DOWN, the time in milliseconds that the data source took to respond;
DOWN, a message explaining the cause of the problem;
Operations of the DataSourceManagementInfo MBean¶
Those data sources that support the ping invocation (JDBC, ODBC, LDAP, OLAP, SAPBWBAPI, SAPERP and SALESFORCE sources) also provide the following operation:
ping(<timeout : long>): Launches an asynchronous ping invocation to check whether this data source is accessible from Virtual DataPort or not.
This operation does not return any value. Instead, the corresponding
DataSourceManagementInfoMBean attributes are updated when the ping ends.
timeoutrepresents the time in milliseconds that the ping invocation will be waiting for an answer from the data source. This parameter is optional. If you provide
NULLas a value, the ping will consider the default timeout, whose value is
