Error description

• The WebSphere for z/OS Runtime does not honor the 10 second
  default connection timeout setting defined by
  com.ibm.CORBA.ConnectTimeout.
  

Local fix

• supply an appropriate value for com.ibm.CORBA.ConnectTimeout.
  Use the adminconsole to specify the desired value.
  To set ORB custom property, click Servers > Server Types >
  Application servers > server_name > Container services > ORB
  service > Custom properties.
  Click New to add a new property to the list. Fill in the name
  com.ibm.CORBA.ConnectTimeout.  Fill in the timeout value. Click
  Apply to save your change. When you finish the changes, click

  *                      controller region hangs during          *

  ****************************************************************
  In the WebSphere Application Server for z/OS controller region,
  all the 25 ACRW threads processing the synchronous connect
  are hung when the remote system is down leaving no free
  threads to handle the timeout. The default timeout value is
  not honored by the existing code as documented in the
  infocenter. The stack trace of a hung thread is as follows:

Problem conclusion

• Code was updated so that for synchronous connect, the
  connection timeout is set in AIOCB structure before calling
  connect. In addition, the default connection timeout value
  is updated to 10 seconds as documented in the infocenter.
  
  APAR PM75048 is currently targeted for inclusion in Fix Packs
  8.0.0.6 and 8.5.0.2 of WebSphere Application Server.
