IT38008: No mechanism to set MQIPT_JVM_OPTIONS for IBM MQ Internet PassThru when run as a service

APAR status

• Closed as program error.

Error description

• MQ IPT running on Windows as a service is not started with the
  mqipt.bat file but through a different process. This process
  is unable to check the MQIPT_JVM_OPTIONS environment variable,
  which is used to set JVM options when starting MQ IPT
  interactively
  
  This results in being unable to set any JVM options for MQ IPT
  when it is running as a server.
  

Local fix

• Run MQ IPT as a standalone application not as a service.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  MQIPT users who use SSLv3 with MQIPT installed as a service on
  Windows.
  
  
  Platforms affected:
  Windows
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  SSLv3 is disabled by default in the Java runtime environment
  (JRE) that is supplied with MQIPT. To enable SSLv3 the Java
  system property com.ibm.jsse2.disableSSLv3=false must be set.
  However, there is no way to set Java properties when MQIPT is
  started as a service on Windows.
  

Problem conclusion

• The MQIPT service on Windows has been enhanced to allow Java
  properties to be set using a value in the Windows registry.
  
  After applying the APAR, to enable SSLv3 for the MQIPT service
  on Windows define a new string value in the registry under the
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MQInternetP
  assThru key. The value should have the following attributes:
  
  Name: MqiptJvmOptions
  Value data: -Dcom.ibm.jsse2.disableSSLv3=false
