———————–
- Redo Buffers in SHOW SGA does not mattch init.ora:log_buffer parameter setting.
- Enforced mininum is set to 4 times thhe maximum database block size.
- Java_pool_size not accounted for in SSHOW SGA or v$sga.
This is a bug that is fixed in 8.1.6.
- Java_pool_size restrictions in 8.1.5..
The default is 20000K.
If specifying in the init.ora, must it must be > 1000K, or will receive
ORA-01078
“failure in processing initialization parameters” error on startup.
