ORA-54538: unexpected gtype

Cause: The gtype of the geometry was not GTYPE_SOLID, GTYPE_SURFACE, GTYPE_CURVE or GTYPE_POINT.

Action: Correct the elemInfo array to fix any invalid gtype and etypes that violate the geometry hierarchy.

ORA-54538: Unexpected GType

ORA-54538 is an oracle error that indicates that an unexpected GType (Globally Unique Type identifier) value has been encountered in the database. GType, or Global Type Identifier, is created during the Oracle installation process. GType is used throughout the database to control the execution of certain functions, such as installation, compatibility, and application development. In Oracle, GType is not user-controlled, which means that any GType value encountered should match the internally-defined GType value.

This error typically occurs when the GType value encountered does not match the GType value expected by the database. It is most common when attempting to run certain functions, such as a query, an installation, or an application. This is because GType is used by Oracle to ensure the correct execution of these tasks. When the GType value does not match, the database is unable to complete the task, and the ORA-54538 error is thrown.

When this error occurs, the most common cause is that a data or application file has been corrupted. Corrupted files can be caused by operating system or hardware failure, or by an unexpected software crash. In rare cases, the GType value may be set incorrectly in the database, which can also cause an ORA-54538 error.

In order to resolve this issue, the corrupted data or application files should be replaced with a backup. If no backup is available, the files should be completely reinstalled. The GType value can also be manually reset in the database, however it is recommended that this is only done by an experienced database administrator. It is important to ensure that the GType value is correctly reset in order to prevent further issues in the database.
