Don, I am way beyond that point. If you set memory_max_target = 0 then start the db, it generates ORA-00849 is thrown.
ORA-00849 SGA_TARGET value was more than MEMORY_MAX_TARGET value.
If SGA_TARGET is unset , then I get ORA-27102: out of memory
Linux-x86_64 Error: 28: No spaceleft on device

You'll likely need to set memory_target and memory_max_target = 0 with scope=spfile, then set sga_target (or the individual pools) accordingly with scope=spfile and then bounce.
Note 749851.1 makes it plain that Hugepages and Oracle 11g AMM do not mix.

The problem is if you unset or set to zero memory_max_target, you get

You can NOT use memory_target or memory_max_target with HugePages. That's a non-starter.

Hi,
two possibile solution:
- Open SQLPlus and even with instance in idle execute:
create pfile='/tmp/pfilename' from spfile='+ASM/path/to/spfile';
Modify the pfile and then following the same procedure create a new spfile from memory
2. Create a standard pfile, startup nomount your instance and do the step 1
3. With asmcmd you may copy the spfile from ASM to disk, using strings command convert it in plain text and then use if as a pfile
BTW, I always avoid to have the spfile in ASM for this and many other similar reasons.
