The enhanced data integrity function is active and running in warning mode (MODE(WARN)). The data set dsn on volume volser is not in the enhanced data integrity exclude list table, enhanced data integrity bypass was not requested, and the data set is being opened for input or output when it is already open for output.
In the message text:
OPEN processing of the data set is allowed to continue.
The enhanced data integrity table was created with the MODE(WARN) keyword and, therefore, enhanced data integrity is running in warning mode. This mode is primarily for debugging or conversion, or both. If this data set should be added to the enhanced data integrity table, then add it to the IFGPSEDI member.
If this data set should be excluded from enhanced data integrity processing, then either the system programmer must update the IFGPSEDI member, or the application programmer must modify the application to set the DCBE exclude flag or to not violate enhanced data integrity. Otherwise, the application would fail if IFGPSEDI is modified to specify MODE(ENFORCE) and the open is for output. If the open is for input and the application is not in error, then this message can be ignored because after MODE(ENFORCE) is activated, input processing will not fail. However, if the application is in error, then it will need to be modified to prevent opening for input when the data set is concurrently open for output.
