60564 - Running the METALIB procedure results in a segmentation violation and duplicate index objects

Problem Note 60564: Running the METALIB procedure results in a segmentation violation and duplicate index objects

When you use the METALIB procedure to update metadata for a database table that has indexes, you might get a Segmentation Violation or an array out of bound error. Also, duplicate index objects are created in the metadata.

When this problem occurs, you see messages similar to the following in the SAS log:

ERROR: An exception has been encountered.

Please contact technical support and provide them with the following traceback information:

The SAS task name is [METALIB ]

Segmentation Violation

When you encounter this problem, jobs requiring table metadata might fail, and you might see unpredictable results in the table metadata.

The problem occurs when the index columns are not returned in a list ordered by index name by the database management system (DBMS) query. PROC METALIB builds an incorrect list for the data source indexes.
