SQL7918 - Reusable ODP deleted

SQL7918
Message Text:	Reusable ODP deleted. Reason code &1.
Cause Text:	An existing Open Data Path (ODP) was found for this statement, but it could not be reused for reason &1. The statement now refers to different files or uses different override options than are in the ODP. Reason codes and their meanings are: Commitment control isolation level is not compatible. The statement contains SQL special register USER or CURRENT TIMEZONE, and the value for one of these registers has changed. The PATH used to locate an SQL function has changed. The job default CCSID has changed. The library list has changed, such that a file is found in a different library. This only affects statements with unqualified table names, when the table exists in multiple libraries. The file, library, or member for the original ODP was changed with an override. An OVRDBF or DLTOVR command has been issued. A file referred to in the statement now refers to a different file, library, or member. An OVRDBF or DLTOVR command has been issued, causing different override options, such as different SEQONLY or WAITRCD values. An error occurred when attempting to verify the statement override information is compatible with the reusable ODP information. The query optimizer has determined the ODP cannot be reused. The client application requested not to reuse ODPs.
Recovery Text:	Do not change the library list, the override environment, or the values of the special registers if reusable ODPs are to be used.

A reusable ODP exists for this statement, but either the job's library list or override specifications have changed the query.

The statement now refers to different tables or uses different override specifications than are in the existing ODP. The existing ODP cannot be reused, and a new ODP must be created. To make it possible to reuse the ODP, avoid changing the library list or the override specifications.
