Question

  Whether Oracle jdbc supports, which version is supported by the highest.

Bug

• Which version of SkyWalking, OS and JRE?
  SkyWalking Version:6.0.0-beta
  OS:linux
  JRE:oracle 1.8

• Which company or project?

• What happen?
  I can't see the DB information again on the Dashboard.

And can't trace any SQL statement information.

When I see the log of agent(skywalking-api.log),I found this error log:

InstMethodsInter : class[class oracle.jdbc.OracleDriver] after method[connect] intercept failure java.lang.ClassCastException: oracle.jdbc.driver.T4CConnection cannot be cast to org.apache.skywalking.apm.agent.core.plugin.interceptor.enhance.EnhancedInstance at org.apache.skywalking.apm.plugin.jdbc.JDBCDriverInterceptor.afterMethod(JDBCDriverInterceptor.java:45) at org.apache.skywalking.apm.agent.core.plugin.interceptor.enhance.InstMethodsInter.intercept(InstMethodsInter.java:105) at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java) at com.alibaba.druid.filter.FilterChainImpl.connection_connect(FilterChainImpl.java:156) at com.alibaba.druid.filter.stat.StatFilter.connection_connect(StatFilter.java:218) at com.alibaba.druid.filter.FilterChainImpl.connection_connect(FilterChainImpl.java:150) at com.alibaba.druid.filter.FilterAdapter.connection_connect(FilterAdapter.java:786) at com.alibaba.druid.filter.FilterChainImpl.connection_connect(FilterChainImpl.java:150) at com.alibaba.druid.pool.DruidAbstractDataSource.createPhysicalConnection(DruidAbstractDataSource.java:1560) at com.alibaba.druid.pool.DruidAbstractDataSource.createPhysicalConnection(DruidAbstractDataSource.java:1623) at com.alibaba.druid.pool.DruidDataSource$CreateConnectionThread.run(DruidDataSource.java:2468)
