Hi all,
One of IBM expert tell our shop to setup the CSA limit =0 in VTAM, but we
found IST561I STORAGE UNAVAILABLE: CRA4 BUFFER POOL problem when one of mq
server abnormal connect/reconnect to our host system. As we set the CSA
limit to 0 therefore VTAM use up all MVS ECSA. All commands cannot be
issued includes VTAM and MVS command. We IPL the LPAR finally. Is it a good
practise to set the CSA limit to 0. Anyone can share ?
Any help will be appreciated.
