Variable size memory is not matching....

Question

Hello, Here is my oracle version..
Oracle Database 10g Enterprise Edition Release 10.1.0.2.0 - Prod
PL/SQL Release 10.1.0.2.0 - Production
CORE 10.1.0.2.0 Production
TNS for 32-bit Windows: Version 10.1.0.2.0 - Production
NLSRTL Version 10.1.0.2.0 - Production
My variable size memory should be exactly same as Java pool, large pool, shared pool.
scott@orcl> show sga
Total System Global Area 171966464 bytes
Fixed Size 787988 bytes
Variable Size 145488364 bytes
Database Buffers 25165824 bytes
Redo Buffers 524288 bytes
scott@orcl> select
2 sum(bytes)
3 from
4 v$sgastat
5 where
6 pool in ('shared pool', 'java pool', 'large pool');
SUM(BYTES)
143369796
The stream pool size should be part of SGA. But it is not showing in v$sgastat view....
In oracle9i, variable size was matching with the above query. Now it is not matching..
Am i missing any thing in my above query? Any help is highly appreicated...
