We'd like to dynamically change SECCACHE values
Is this safe to do in a production environment?
TSS MODIFY(SECCACHE(OFF))
TSS MODIFY(SECCACHE(SIZE=2048,INDEX=30000,EXP=6,WARN=80))
Yes it is safe.
If you turn off SECCACHE, it will free and then reallocate the space at whatever parameters you request.
When you restart SECCACHE it will always reallocate regardless if you change the size parameter or not.
