CAZ3962E
Import failed: unable to generate unique sample file name;
DIAG=(aa, bb).
Explanation
The Import operation was unable to generate a unique dataset name for the file that will contain the imported observation. The value in aa represents the input import dataset name; and bb represents the non-unique generated dataset name.
System action
Application Performance Analyzer fails the import operation.
Operator response
This error may be related to the CONFIG SAMPLE SampleDSN parameter value. It may contain a model dataset name that would generate non-unique dataset names. For example: "SampleDSN=SYS3.CAZ0.D&LYYMMDD..SF". This model dataset name would allow only one unique sample file to be created per day. Correct the SampleDSN, recycle the Application Performance Analyzer started task, and retry the operation.
