问题
I'm performing WSO2 API manager + Analytics 2.0 POC now. When i change datasource from H2 to Oracle, in wso2am-2.0.1-SNAPSHOT, there are 2 data source config files: master-datasources.xml & metrics-datasources.xml, according Installing and configuring the databases, there should be WSO2AM_DB, WSO2UM_DB and the WSO2REG_DB datasource configurations, but i just find WSO2_CARBON_DB & WSO2AM_DB, so my questions are
- Is WSO2_CARBON_DB = WSO2UM_DB + WSO2REG_DB?
- for WSO2_METRICS_DB, according Enabling Metrics and Storage Types, if we enable JDBC storage, can we store all components metrics information in one shared db or it needs one db per component(local)?
- What's WSO2_MB_STORE_DB used for? from the scripts, it's for Message Store and Andes Context Store. Can we keep to use H2 in prod. cluster env.?
When i config wso2am-analytics-2.0.0-SNAPSHOT, i have below questions:
- Can we share WSO2_CARBON_DB setting for both APIMGRT related components and analytics? or it's better to not share?
- For WSO2AM_STATS_DB, is analytics resposible to aggregate and write to it, APIMGRT responsible to read? Which APIMGRT components need to read it?
- For analytics related store, it supports RDBMS, Cassandra, HBase, but it does not support mongodb, right?
- for GEO_LOCATION_DATA, What's this used for? Can we just use H2 in prod. env.?

APIM:
1) In default pack, yes. But in a production environment, it is recommended to separate them as WSO2_CARBON_DB, WSO2UM_DB and WSO2REG_DB (Please note you need WSO2_CARBON_DB too, to store local data. And this can be an h2 database)
2) You can have a shared DB
3) WSO2_MB_STORE_DB is required only if you use Advanced Throttling. Tables for this are created by APIM itself. So you don't need to run any scripts on it.
APIM Analytics:
1) You can share WSO2UM_DB and WSO2REG_DB. But don't share (local) WSO2_CARBON_DB.
2) Store and Publisher
3) See WSO2 DAS with MongoDB
4) GEO_LOCATION_DATA is used for Geolocation Based Statistics. H2 is not recommended.
