Download WSO2 BAM 2.0 from location: http://wso2.com/products/business-activity-monitor.
Change port offset of BAM to 1 by editing the file <BAM_HOME>/repository/conf/carbon.xml file (search for the offset node).
```
<Offset>1</Offset>
```
This increments all ports used by the server by 1, which means the BAM server will now run on port 9444. Port offset avoids possible port conflicts when multiple WSO2 products are run in same host.

Copy the file <APIM_HOME>/statistics/API_Manager_Analytics.tbox to directory, <BAM_HOME>/repository/deployment/server/bam-toolbox. If you use Oracle DB to store statistical data, copy API_Manager_Analytics_Oracle.tbox instead.

If this folder is not in the BAM installation home by default, create it and copy the file.

Note
The sample API

Manager Analytic Toolbox : A toolbox is an installable archive, with a .tbox extension. It contains necessary artifacts that models a complete usecase, from collecting data, analyzing through defined Hive scripts to summarizing data through gadgets, Jaggery scripts and other dashboard components.

_Manager_Analytics toolbox works fine when the BAM port offset is 1 like we did in the previous step. But, if you use a different offset to BAM, you must change the am_stats_analyzer script of the toolbox accordingly using the following steps:

Go to BAM Management Console
Select Analytics > List menu
Click Edit on am_stats_analyzer_330
Change the cassandra.port value to 9161+ <BAM offset>

Configure a database to which BAM can write analyzed information to. This information is retrieved by the API Publisher before displaying on the corresponding statistical dashboards.

Specify the data source definition in <BAM_HOME>/repository/conf/datasources/master-datasources.xml file as follows.

WSO2AM_STATS_DB is the datasource used to fetch analytical data. This example uses an H2 database. If you want to use a different database, see Changing the statistics database.
Note: The JNDI config names here must match the ones defined earlier in APIM.

Because you changed the default BAM port in step 2 above, you must change the Cassandra port given in JDBC connection url in the following datasource configuration found in master-datasources.xml file. Since the port offset is 1, the Cassandra port must be 9161.

For a list of default ports used by WSO2 products, see Default Ports of WSO2 Products.

Note
If you run the Hive scripts before changing the default Cassandra port according to the BAM port offset, you keep getting an exception. To overcome this, add the following line at the beginning of the Hive script and rerun. drop table <hive_cassandra_table_name>;

Restart BAM server by running <BAM_HOME>/bin/wso2server.[sh/bat].

If you want to host the BAM server on a different machine or change the running port, you must edit the <APIUsageTracking> node in <APIM_HOME>/repository/conf/api-manager.xml file as follows:
