Circular ELB reference in file filename
The ELB being created is also directly or indirectly referenced as input. For example, the following set of dblink commands will cause this error:
dblink -l util util.dbo mylib.elb dblink -l mylib mylib.dbo util.elb
The first command creates util.elb and links it against mylib.elb. The second command tries to create mylib.elb and link util.elb against it. However, when util.elb is opened and the reference to mylib.elb is encountered, mylib.elb will be opened and a circular reference occurs.
