Downloading IBM Business Process Manager V8.5.7 Cumulative Fix 2017.03

APAR status

• Closed as program error.

Error description

• When an HTTP request is sent from an IBM WebSphere Process
  Server SCA HTTP binding, the HOST header is not set in the
  request message after
  com.ibm.ws.http.ProxyTunnelHosts is enabled. After the request
  is forwarded to the target service, some unexpected errors might
  occur.

Local fix

• According to the HTTP 1.1 SPEC, SCA HTTP Import Binding will set
   the HOST header with the correct value automatically when the
  custom property is enabled.
  

Problem summary

• When com.ibm.ws.http.ProxyTunnelHosts is enabled for an SCA HTTP
   import binding, the HOST header is not set properly. As a
  result, a default HOST header is appended and the URL not
  constructed correctly. Then, some unexpected error occurs.
  
  According to the HTTP 1.1 SPEC, the HOST header should be set
  with correct value to avoid this error.

Problem conclusion

• A fix will be included in IBM BPM V8.5.7 cumulative fix 2017.03.
  
  To enable this function, you must add a new JVM custom property
  by using the WebSphere Application Server administrative
  console:
  
  1. Select Servers > Server Types > WebSphere application servers
  > server_name.
  2. Under Server Infrastructure, select Java and process
  management > Process definition > Java virtual machine > Custom
  Properties.
  3. Add the com.ibm.ws.http.UseURLHostForHostHeader custom
  property with value "true".
  4. Repeat this step for all JVMs in the environment , if
  required.
  

Temporary fix

• According to the HTTP 1.1 SPEC, SCA HTTP Import Binding will set
   the HOST header with the correct value automatically when the
  custom property is enabled.
