Configuring WSO2 STATS_DB

问题:

I have configured API Manager 2.0.0 & API Manager Analytics Pack to use MySQL databases.
For each server, there exists a WSO2AM_STATS_DB. I have given these differing names on my MySQL server. I have also pointed my datasources in master-datasources.xml(for APIM) & stats-datasources.xml(for Analytics) to the relevant databases.
I couldn't find any relevant schema(dbscripts) for these databases in their respective packs.

On running, the Analytics database is populated but the APIM database isn't and throws an exception. The Analytics database not only gets the schema but also the invocation details of my API. I am unable to get the stats on my dashboard though.

Previously, I (unwittingly) configured the h2-repository stats database to be the same for both servers (due to the folder structure) and was able to get all the statistics on my dashboard in the publisher.

Other configurations I have tried : On the MySQL Server, pointed it to the same database (the Analytics one with the schema) but with no results on my dashboard (after waiting for a while).

回答1:

Both datasources (WSO2AM_STATS_DB) in 2 servers should be pointed to the same database. There are no database scripts for this. Tables are created automatically.

By default in both servers, Stats DB path comes like this. (note ../ part)

<url>jdbc:h2:../tmpStatDB/WSO2AM_STATS_DB;DB_CLOSE_ON_EXIT=FALSE;LOCK_TIMEOUT=60000;AUTO_SERVER=TRUE</url>

So if you extract both servers to the same directory as mentioned in this doc, both datasources will be pointing to the same database (inside tmpStatDB) like this.

/parent_dir
     |__wso2am-2.0.0/
     |__wso2am-analytics-2.0.0/
     |__tmpStatDB/

So, what happens here is, wso2am-analytics writes stats data to shared database, then apim reads it and shows data on its databases.
