Hi! Thx, I will try registry 3.6.0. The same problem exist in esb 3.0.1 when it's configured with Jdbc registry model. When it is planned to release next esb version which may include this fix also?

I am using Greg 3.5.1 Currently I workarounded this adding a ping task to esb which retrieves some resource from registry by rest every 5min. We have a similar solution for this issue by adding validation query, but with G-Reg 3.5.1 there's minor bug with validation Query, We have a patch for this but it's not publicly available. If you are going to use G-Reg 3.6.0, you will be able to use a simple validationQuery(SELECT 1) in registry.xml and user-mgt.xml and keep the connections live.

I have configured registry with MySQL. All works fine until registry is idle for 20hours. After that I when I try to use RegistryClientUtils.importToRegistry I have ‘User is not authorized to add the resource to /_system/governance/’ and in registry logs shows: ERROR - Failed to start new registry transaction. {org.wso2.carbon.registry.core.jdbc.Em beddedRegistry} com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 83,440,226 milliseconds ago. The last packet sent successfully to the server was 83,440,226 milliseconds ago. is l onger than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connec tion validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem. at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:513) at com.mysql.jdbc.Util.handleNewInstance(Util.java:409) To workaround this I have tried to add autoReconnect=true: <dbConfig name="wso2registry"> <url>jdbc:mysql://10.100.64.65:3306/registry?autoReconnect=true<http://10.100.64.65:3306/registry?autoReconnect=true></url> <userName>root</userName> <password>root</password> <driverName>com.mysql.jdbc.Driver</driverName> <maxActive>50</maxActive> <maxWait>60000</maxWait> <minIdle>5</minIdle> <validationQuery>SELECT 1</validationQuery> </dbConfig> And it’s work fine when database is restarted : I have ‘User is not authorized to add the resource’ only once and second attempt is successful. But again, when 20hours passed I can not import nothing to registry using RegistryClientUtils even from 50th attempt: FATAL - Failed to add the root collection to the coreRegistry. va.lang.NullPointerException at org.wso2.carbon.registry.core.jdbc.dao.ResourceDAO.getVersion(ResourceDAO.java:224) at org.wso2.carbon.registry.core.jdbc.dao.ResourceDAO.resourceExists(ResourceDAO.java:166) at org.wso2.carbon.registry.core.jdbc.dao.ResourceDAO.resourceExists(ResourceDAO.java:183) at org.wso2.carbon.registry.core.session.UserRegistry.addRootCollection(UserRegistry.java:301) at org.wso2.carbon.registry.core.session.UserRegistry.init(UserRegistry.java:240) at org.wso2.carbon.registry.core.session.UserRegistry.<init>(UserRegistry.java:187) at org.wso2.carbon.registry.core.session.UserRegistry.<init>(UserRegistry.java:122) REST API becomes broken, but it is possible to manipulate with registry from GUI. The only solution which helps is to restart the registry. 1) Does everyone know how to fix this? 2) Why c3p0 pool is not used to handle this?
