How to increase SGA_MAX_SIZE ?
This is my current SGA Settings..
SQL> show sga
Total System Global Area 320308312 bytes
Fixed Size 730200 bytes
Variable Size 285212672 bytes
Database Buffers 33554432 bytes
Redo Buffers 811008 bytes
To install Oracle 22.214.171.124 patch I need to increase Shared_pool_size and JAva_pool_size to atleast 150M each.
My current Shared_pool_size=117440512 and JAva_pool_size =117440512.
Now , if i inccrease both shared_pool_size and JAva_pool_size to 150M, then my Total SGA Size will be around 400MB. But init.ora file parameter shows SGA_MAX_SIZE = 320308312 bytes.
So will that be a problem, if i increase the Shared_Pool_size and Java_pool_size ?....
basically how do increase the Whole SGA Size ?....from 320MB to say 500MB ?....
edit your initSID.ora file and set SGA_MAX_SIZE=500M (and your other parameters that needed to be changed)
How do we calculate the funky numbering we see for all these parameters ?...
like for eg. 32M = 323459083 bytes stuff like that ?..
How is the MAth done ?....can anyone give me exactly how we can come up exact number to put in init.ora file for a say 150MB?...
i have some vague idea like 150 *1024 * 1024 or something like that.
Can anyone explain how it is done ?...
errr dont you know 1k is 1024 bytes?!?!?
i just did that math...
my SGA shows 320308312 bytes...so looks like i have 320MB SGA.
so to calculate 320MB manually...
so 320*1024*1000 = 32680000 which is not equal to 320308312 as shown by SGA...
Iam little confused here...
1KB = 1024 bytes
1MB = 1024 * 1024 bytes = 1048576 bytes, and so on
