Local fix

Problem summary

  • During the initialization of zstream in the native
    compression/decompression APIs, uninitialized storage may cause
    this stream to use software compression or decompression rather
    than zEDC Express (hardware) compression or decompression when
    zEDC Express adapters are available. Please do refer to zEDC
    APAR OA44031 for more details.
    

Problem conclusion

  • This APAR will be fixed in the following Java Releases:
       7    SR7       (7.0.7.0)
       7 R1 SR1       (7.1.1.0)
    .
    The zEDC code in the z/OS JDK has been updated to properly
    initialize storage to prevent a fallback to software compression
    when zEDC Express adapters are available.
