Re: Strange error when resizing MEMORY_TARGET

Thanks Han.

Unfortunately that did not work. I set all targets to the exact value that they currently occupy, i.e.:

shared pool = 1280M
large pool = 128M
streams pool = 128M
java pool = 256M

pga_aggregate_target = 2496M
sga_target = 4672M
db_cache_size = 2752M

Setting memory_target to 16G and even to 20G ( i.e. memory_max_target) still gives the same error "ORA-00846: could not shrink MEMORY_TARGET to specified value" :(
