For Oracle JDBC driver version, the workaround is to use -Doracle.jdbc.thinLogonCapability=o3 as a JVM startup option.

  • Note that this property is ignored for Oracle JDBC driver version


  • If the Enterprise Manager is invoked as a service:

    File : EMservice.conf
    location :<introscope install dir>\bin
    Modification Required : Add a new parameter "wrapper.java.additional.<n>=-Doracle.jdbc.thinLogonCapability=o3".
    (where <n> is the next number in sequence) to the # Java Additional Parameters section.

  • For all Enterprise Managers invoked by either method:

    Location : <introscope install dir>/config
    Modification Required : Append "-Doracle.jdbc.thinLogonCapability=o3" to the jvm option for:
         Defect Aggregation (defects.jvmArgs)
         Stats Aggregation (dailystats.jvmArgs)
