Note
Encryption and compression messages that are encrypted must be decrypted before they reach the BMC API to be processed by the BTM WebSphere MQ API exit. To ensure that the exits are processed in the correct order, the decryption API exit must have a larger sequence number than the BTM WebSphere MQ API exit. In addition, any compressed messages must be uncompressed before the BTM WebSphere MQ API exit can read them.
