Increasing the stack size on Windows, Linux, and UNIX systems
Increase the stack size on Windows, Linux, and UNIX systems by setting the MQSI_THREAD_STACK_SIZE environment variable to an appropriate value.
When you restart brokers that are running on the system, they use the new value.
The value, in bytes, of MQSI_THREAD_STACK_SIZE that you set is used for every thread that is created in a DataFlowEngine process. If the execution group has many message flows assigned to it, and you set a large value for MQSI_THREAD_STACK_SIZE, the DataFlowEngine process needs a large amount of storage for the stacks.
Set this environment variable to at least 48 KB. The
default values are:
- Linux and UNIX
- 1 MB
- AIX®
- 2 MB
- z/OS®
- 50 KB
- Windows
- Determined by the operating system.
