Question & Answer

Question

This document addresses the question of whether there is a way to restrict users from using NONRECOVERABLE loads. It also describes the usage of the DB2_LOAD_COPY_NO_OVERRIDE registry variable.

Answer

Is there a way to restrict users from using NONRECOVERABLE loads?


No. The DB2_LOAD_COPY_NO_OVERRIDE registry can be set on the server to automatically convert:

• COPY NO Loads to NONRECOVERABLE loads, or
• COPY NO Loads to COPY YES loads.

There is no way to convert NONRECOVERABLE loads to any other type of load operation.

How to use DB2_LOAD_COPY_NO_OVERRIDE registry variable

The DB2_LOAD_COPY_NO_OVERRIDE can be set on the server as follows:
db2set DB2_LOAD_COPY_NO_OVERRIDE="COPY YES to <path name>"
... where <path name> is a path that the instance owner has permission on.

Here is an example of how the registry variable can be used:

1. Create a directory named /TMP/myinstance that the instance owner has write access to.
2. Run the following commands:
   db2sampl
   db2 update db cfg for sample using LOGRETAIN ON
   db2 terminate
   db2 backup db sample
   db2stop
   db2set DB2_LOAD_COPY_NO_OVERRIDE="COPY YES to /TMP/myinstance"
   db2start
   db2 connect to sample
   db2 "export to employee.del of del select * from employee"
   db2 "load from employee.del of del modified by coldel, replace into employee COPY NO"

You will note that the COPY NO load above gets converted to a COPY YES and the COPY YES load would be placed on /TMP/myinstance.

Note: The registry variable can be set to any valid COPY YES syntax. Refer to the LOAD command for an example of the COPY YES syntax.
