Using DB_NK_CACHE_SIZE BUFFER

Question

Please,
Below are steps I did in order to move the all_customer_photo table into the photos tablespace.the photos tablespace was created with a 16K block size
1. ALTER SYSTEM SET DB_16K_CACHE_SIZE=100MB SCOPE=SPFILE;
2. CREATE TABLESPACE PHOTOS DATAFILE 'C:\oracle\product\10.2.0\oradata\PHOTOS.dbf' SIZE 10M
BLOCKSIZE 16K;
3. alter table all_custom_photo move tablespace photos;
4. drop index ix_all_customer_photo
5. create index ix_all_customer_photo on all_customer_photo(all_customer_id) tablespace photos compute statistics;
Verifications I did afterwards
1.
SQL> select tablespace_name,block_size from dba_tablespaces where tablespace_name='PHOTOS';
TABLESPACE_NAME BLOCK_SIZE
PHOTOS 16384
2.
INDEX_NAME TABLESPACE_NAME
IX_ALL_CUSTOM_PHOTO PHOTOS
My question:
There is a command that I can verify if the table all_custom_photo will be really cached in the DB_16K_CACHE_SIZE?or I can only rely on verifications done above?
Thanks

Answer 1

I did no specified 16k for the index cause I dont have yet any buffer of 16k, all my tablespace are 4k...
IMP-00017: following statement failed with ORACLE error 1450:
"CREATE INDEX "PARAMETROS_GLOBAIS2" ON "PARAMETROS_GLOBAIS" ("DESCRICAO" ) PCTFREE 10 INITRANS 2 MAXTRANS 255 STORAGE(INITIAL 327680 FREELISTS 1 FREELIST GROUPS 1) TABLESPACE "INDX" LOGGING"
IMP-00003: ORACLE error 1450 encountered
ORA-01450: maximum key length (3118) exceeded
any suggestion for this error or the best way would be creating the 16k tablespace ?
Now I reduced the large pool from 144 to 16M and did the alter system in just the spfile
SQL> ALTER SYSTEM SET LARGE_POOL_SIZE=16M SCOPE=SPFILE;
SQL> ALTER SYSTEM SET db_16k_cache_size=64M SCOPE=SPFILE;
System altered.
Do you think its gonna work well after the re-start ?
