WSO2 API manager and Identity Server Integration - wso2

Question

I tried to integrate wso2IS 5.0.0 and wso2AM 1.7.0 by following documentation.
https://docs.wso2.com/display/CLUSTER420/Configuring+the+Identity+Server+5.0.0+with+the+API+Manager+1.8.0+or+1.7.0
But following exception caused
[2016-11-29 15:31:02,320] ERROR - RegistryContext Couldn't find db configuration 'wso2registry'
[2016-11-29 15:31:02,422] ERROR - EmbeddedRegistryService Failed to configure the embedded registry. Invalid data access manager.

Answer 1

The issue is that you have removed below section from registry.xml
<dbConfig name="wso2registry">
<dataSource>jdbc/WSO2CarbonDB</dataSource>
</dbConfig>
Th doc you are referring explicitly says not to do that.
When doing this change, do not replace the existing for
"wso2registry". Simply add the following configuration to the existing
configurations.
