NOTE: If you are not sharing the ZMSENVT2 member parms across a SYSPLEX, you will need to perform Steps 1 through 3 for each MSS that you have installed before completing Steps 4 and 5.
To change your TLS 1.0 level to TLS 1.2, you will first need to configure the Message Service Server environment variables.
1) Edit the ZMSENVT2 member in the <your deployment HLQ>.CAW0OPTV dataset
2) Insert this line:
IJO="$IJO -Dcom.ibm.jsse2.overrideDefaultTLS=true"
The line should be inserted above the line that states:
export IBM_JAVA_OPTIONS="$IJO "
3) Stop and start the Message Service server started task
For example:
/p ZMSSTART
/s ZMSSTART
4) You will now need to make changes on the MOI appliance. File transfer the runscript_1632315435095.sh attached to this Knowledge Doc to the MOI appliance linux machine.
5) Then follow these steps:
chmod +x runscript.sh
./runscript.sh
