APAR status

  • Closed as program error.

Error description

  • A remotely (eg. HTTP/HTTPS) retrieved document retained in the
    document cache might become invalid if the TTL is reached and
    the HEAD response from the remote endpoint includes a
    Content-Length of 0.  This will invalidate the previous content
    length used and make the cached document irretrievable.
    

Local fix

  • 1) Clear the document cache to temporarily alleviate
    2) Disable the document cache (Inside XML Manager->Document
    Cache Policy, remove the TTLs or set to no-cache)
    

Problem summary

  • WTX binary transform action might fail to retrieve data from the
     remote DPA file if the document in the cache is expired.
    

Problem conclusion

Temporary fix
