Excessive Time to Open SQL Developer Data Model

(Doc ID 2388312.1)

Last updated on APRIL 19, 2018

Applies to:

Oracle SQL Developer Data Modeler - Version 17.4 and later
Information in this document applies to any platform.
Oracle Developer SQL Modeler 17.4 to 18.1

Symptoms

SQL Developer Data Modeler is suddenly taking about 9-10 minutes to open a model (relational and physical) on a MAC computer. This particular model is not big, only has about 20 tables.

If try to open only the relational model, it is fast. If open both the relational and the physical, then it takes minutes.

Exporting the model behaves the same way.

Using Look and Feel "Oracle" is faster than using "Mac OS X".

Using Data Modeler version 18.1 displays same behavior.

Changes

 At some point changed design properties from "Model in many files" to "Model in one file".
