Description
The MQBUFSZ and UBUFSZ parameters, which are aliases of each other, specify the default Universal Buffer size. The Universal Buffer, or user buffer, is enlarged as needed, but you cannot make it smaller than the value of UBUFSZ.
The physical size limit for the Universal Buffer is 2 gigabytes.
The buffer is allocated only if referenced in a User Language request. It is released when the user logs out.
