David,

This looks like something we need to investigate. Please make a Bugzilla
entry for this, if you haven't already.

Hi,

I am wondering if it is a bug with data tools connectivity framework, I was
running into OutOfMemory when making consecutive (>50) connections to
oracle db server, I suspect there is an memory leak out there, here are the
steps to reproduce:

Environment: DTP 0.7 Eclipse 3.1 Compatibility Pack SDK

1. Open Database Development perspective
2. Click "New Connection Profile" button to launch "New Connection Profile"
wizard
3. Choose "SQL Model-JDBC" Connection, press "Next"
4. Enter name and press "Next"
5. On the driver list, select "Oracle JDBC Driver for Oracle 10" (create
one if not available on the list)
6. Enter valid Database, URL, User name and password information
7. Click "Test Connection" button
8. Repeat step 7 for >50 times

Same problem for DTP 0.9 RC3 (Eclipse 3.2)

Thanks,
David

Hi Larry

I did figure out this bit.

Following derby's SQL model example; I tried creating a model reverse
engineered from Annotated Java source. The wizard that handle the process
didnot pick the java sources. I found ClassCastException when I checked the
workspace log file. I sent an email to this mailing list with Subject "CCE
during Annotated Java Import"; but no response yet. I have to get this
working ASAP.

      Anil,

      Actually, the getters on DatabaseVendorDefinition are for "Schema
      Definition", "Sequence Definition", etc.  These getters are used get
      the definition objects that contain properties describing the
      database's support for features of those objects.  For instance, the
      Table Definition object has methods such as isAuditSupported(),
      isDataCaptureSupported(), isEncodingSupported(), etc.   For what you
      are trying to do, the dbdefinition is not involved at all.

      I don't have any experience extending the SQL model so I cannot be of
      any help there, however there is derby model extension in DTP that
      can be used as an example in the
      org.eclipse.datatools.modelbase.derby plug-in.
