Oracle TopLink 11g Release 1 (11.1.1.6.0) support for Oracle11g (11.2.0.4)

3216875Apr 8 2016 — edited Apr 27 2016

Hi,

In the Toplink release support, I could see that Oracle TopLink 11g Release 1 (11.1.1.6.0) supports the DB version Oracle11g (11.2.0.3). Can someone from Toplink team let me know whether Toplink 11.1.1.6.0 supports Oracle11g (11.2.0.4). If it supports, are there any changes needed in Toplink configuration or Datasource configuration.

Oracle TopLink 11g Release 1 (11.1.1.6.0) and 12c Database Support

The rule you have described will work if "the order total" is an attribute on the Line Items entity, which is the parent of the PartsDetails relationship. If you are getting the error message described you should do the following:

1. check that the relationship text for Line ITems --> PartDetails is "the PartDetails"

2. check that you have a number or currency attribute with the text "the order total" on the Line Items entity.

3. If you are rely on an automatically created attribute, you should change the attribute to "the Line Items order total". If you include the text of an entity in an attribute, the automatically created attribute will be placed in the correct entity, and then the InstanceSum statement will be correct for the attribute.

Hi Frank, It is not working. If I flatten the structure keep 1 entity (line item details) under global, InstanceSum works fine. For nested datamodel relationship, instanceSum not working.

PathhibHW,

This is almost certainly becuase the rule is trying to create the attribute "the order total" on the global entity, in this case it cannot sum across all line items, all part details.

Have a look at my suggestions 2. and 3. make either of those changes and your rule should work.

Hi Frank, Thanks a lot. It is working now. Can you please share the scenario for "Reasoning across entity instances" ForScope statement. Thanks.

Answer

Glad to hear you got it working.

Due to quirks of our rule parser, you can't sum across a deep relationship structure in one rule using scope operations. However with a few itermediate attributes it becomes pretty simple.

To sum all the PartDetails of a quote. I would use the following two rules:

the line item's total = instancesum(the PartDetails, the PartDetails ItemPrice)

the quote's total = instancesum(the line items, the line item's total)

You have to sum the totals across one relationship at a time.

Cheers

Frank
