Hi Shazni,
I checked the code for removeCache method and found that cacheKey is
calculated as below.
*String connectionId = (dataBaseConfiguration.getUserName() != null?
dataBaseConfiguration.getUserName().split("@")[0]:dataBaseConfiguration.getUserName())
+ "@" + dataBaseConfiguration.getDbUrl(); cacheKey =
RegistryUtils.buildRegistryCacheKey(connectionId, tenantId, path);*
But in registry.xml we have below element too,
*<cacheId>root@jdbc:mysql://mysql1.appfactory.private.wso2.com:3306/dbGovernanceCloud
<http://mysql1.appfactory.private.wso2.com:3306/dbGovernanceCloud></cacheId>*
Shouldn't we read the cacheId element first and calculate as above if
cacheId element is not defined? Or did I misunderstand the configuration?
thank you.
