WSO2 API Manager 1.6.0-什么是正确的数据库配置？

Question

I have an installation of APIM 1.6.0 and a configuration as follows for each component. Databases: WSO2CarbonDB, WSO2UM_DB, WSO2REG_DB, WSO2AM_DB

I've left the entry in all of the registry.xml files that points to carbon by default, and added the gov registry configuration:

<currentDBConfig>wso2registry</currentDBConfig>
<dbConfig name="wso2registry">
    <dataSource>jdbc/WSO2CarbonDB</dataSource>
</dbConfig>
<dbConfig name="govregistry">
        <dataSource>jdbc/WSO2REG_DB</dataSource>
    </dbConfig>
    <remoteInstance url="https://localhost:9446/registry">
        <id>gov</id>
        <dbConfig>govregistry</dbConfig>
        <readOnly>false</readOnly>
        <enableCache>true</enableCache>
        <registryRoot>/</registryRoot>
    </remoteInstance>
    <mount path="/_system/governance" overwrite="true">
        <instanceId>gov</instanceId>
        <targetPath>/_system/governance</targetPath>
    </mount>
    <mount path="/_system/config" overwrite="true">
        <instanceId>gov</instanceId>
        <targetPath>/_system/nodes</targetPath>
    </mount>

For the user-mgt.xml file I left the original carbon entry and added the user db entry:

   <Property name="dataSource">jdbc/WSO2CarbonDB</Property>
   <UserStoreManager class="org.wso2.carbon.user.core.jdbc.JDBCUserStoreManager">
<Property name="dataSource">jdbc/WSO2UM_DB</Property>

In the api-manager.xml file I added:

 <DataSourceName>jdbc/WSO2AM_DB</DataSourceName>

This was done on the Publisher node, Store node, Gateway node, and KeyManager node. What I expected would happen was that all of the components would use the databases as follows:

• WSO2UM_DB would get used for UM_ tables interaction from all components.
• WSO2REG_DB would get used for REG_ tables interaction from all components.
• WSO2AM_DB would get used for API_ tables interaction from all components.
• I really didn't expect the WSO2CarbonDB to get used.

What I have seen from database traces is that the following happens:

• WSO2AM_DB is used by the Publisher for API_ tables. (I have not seen any other components access yet).
• WSO2UM_DB is used by all components for UM_ tables.
• WSO2REG_DB is used by all components for REG_ tables.
• WSO2CarbonDB is used by all components for both UM_ and REG_ tables updates.

The thing that suprised me was that for all components: Publisher, Store, Gateway, and Key Manager the WSO2CarbonDB was used for both UM_ and REG_ tables. This was for inserts, updates, deletes, and selects.

Is that expected? Or should I have removed/updated the WSO2CarbonDB to be the User or Registry database?

Answer 1

If you need jdbc/WSO2UM_DB to be the database for the user store of all the comonents, then you have to change the default datasource property value to be jdbc/WSO2UM_DB in user-mgt.xml. So you don't need to keep the jdbc/WSO2CarbonDB in there.

<Property name="dataSource">jdbc/WSO2UM_DB</Property>

WSO2REG_DB to be the database for registry in all components, configure registry.xml same as your given configuration. Then gov and conf registry space of all of those will get pointed to WSO2REG_DB.

Also note that default WSO2CarbonDB will be used as the local registry of each and every component.

Answer 2

You could create all the database scripts into one single database schema. Point all your datasource (master-datasources.xml) to this database and schema.

Here is my master-datasources.xml; it is used by Puppet. Puppet is replacing the <%= %> tags during provisioning.
