APAR status
Closed as program error.
Error description
.NET code running inside an integration server can be dynamically updated by replacing the DLL assemblies on disk. This process is called a "hot swap deploy" and is enabled by default. An abend may occur when performing a hot swap deploy if the .NET code being redeployed is accessed from a message flow, e.g. in a .NET compute node or in an ESQL procedure call. This is due to improper locking of message flows during the hot swap. It is strongly recommended to disable hotswapping in production environments.
Local fix
Use an DotNetAppDomain configurable service or policy to disable hot swapping via the AllowHotSwapDeploy attribute. Alternatively, stop all message flows conusming the .NET assemblies before performing the hotswap.
Problem summary
**************************************************************** USERS AFFECTED: All users of .NET HotSwap deploys in IBM Integration Bus v10, IBM App Connect Enterprise v11, or v12. Platforms affected: Windows on x86-64 platform **************************************************************** PROBLEM DESCRIPTION: .NET code running inside an integration server can be dynamically updated by replacing the DLL assemblies on disk. This process is called a "hot swap deploy" and is enabled by default. An abend may occur when performing a hot swap deploy if the .NET code being redeployed is accessed from a message flow, e.g. in a .NET compute node or in an ESQL procedure call. This is due to improper locking of message flows during the hot swap. It is strongly recommended to disable hotswapping in production environments.
Problem conclusion
All message flows will now be locked and stop processing messages during a hotswap deploy. Message processing will resume once the hotswap has been completed. Hotswapping should not be left enabled in a production environment. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v10.0 10.0.0.26 v11.0 11.0.0.17 v12.0 12.0.4.0 The latest available maintenance can be obtained from: http://www-01.ibm.com/support/docview.wss?rs=849&uid=swg27006041 If the maintenance level is not yet available,information on its planned availability can be found on: http://www-1.ibm.com/support/docview.wss?rs=849&uid=swg27006308 ---------------------------------------------------------------
