Increasing SGA_MAX_SIZE in Oracle 10.2.0.1

Question

Hi,
we have successfully upgrade our database from 8.1.7.0 to 10.2.0.1
now in the database control, SGA max size is 524MB
i want to increase it, as to increase the size of SHARED_POOL_SIZE and DATBASE_BUFFER size
i have checked the init.ora file, in that there is no parameter mentioned as sga_max_size
from where and how to increase the SGA_MAX_SIZE in 10g version ?
with regards

Answer 1

Hi,
Database is using init.ora file in the pfile folder
In the init.ora file i have increased the SGA_MAX_SIZE parameter to 1024Mb from 524Mb
Now, from dbcontrol screen, Automatic Shared Memory Managment is Disabled and i want to make it ENABLE
now when i click on ENABLE button, on the next page it shows total SGa size i.e 332 Mb
and further wheni click on "OK" button for ASSM configuration, it shows the error as below :-
1.) SGATargetSize - ORA-02097 : parameter cannot be modified because specified vale is invalid ORA : cannot set sga_target due to existing internal settings, see alert log for information
in the alert log , it mentions
Cannot set sga_target with db_block_buffers set
and
Alter system set java_pool_size='0' SCOPE=MEMORY;
2) sharedPoolsize - ORA-02097 parameter cannot be modified because specified value is invalid ORA-04034: unable to shrink pool to specified size
now i just mentioned the memory component details for reference :
shared pool : 104 Mb
buffer cache : 169 Mb
large pool : 0
java pool : 4 Mb
other : 54 Mb
total SGA -- 332 Mb
Maximum SGA Size -- 1024 Mb
how to make ASSM Enable ???
With Regards
