Any operation that writes to a SAS catalog may potentially corrupt the catalog preventing future additions to the catalog. The problem occurs as the catalog is being closed. Specifically, if the current page becomes full during the close operation thus requiring an additional page, the header information does not correctly track the new page. If a catalog entry is shortened on a subsequent operation, the catalog may be incorrectly truncated losing the page that was not correctly tracked. This prevents the catalog from being updated again but does not prevent read access.

The following error message occurs when an attempt is made to update a catalog where this corruption has occurred. It can occur in any product or procedure which writes to a catalog.

To circumvent the problem, copy the catalog to a temporary location and then recreate it. The problem with the header information is corrected in the copying process. For example, assume a catalog named MYLIB.CAT1 has become corrupted. To correct the problem, you could use the following code.
