Dear List,

I am monitoring a database, & I findout there is a transaction which runing a long time and others are waiting for this transaction, this transaction have 8,000,000 consistant gets with only 1 Physical I/O. My question is, what I have to do except the SQL tuning to make this transaction faster, we have done all the necessary tuning on all the SQL query's.
Here is a copy of ora.ini:

Oracle 8.1.7.4 on sun solaris 2.8

background_dump_dest = /oracle/admin/cmstst/bdump compatible = 8.1.7.4

control_files = "/cmsdb/cmstst/control02.ctl"
control_files = "/oralogs1/cmstst/control03.ctl"
control_files = "/oracle/oradata/cmstst/control01.ctl"
core_dump_dest = /oracle/admin/cmstst/cdump
db_block_buffers = 10000				??? this need to

increase?

db_block_lru_latches = 4
db_block_size = 8192
db_file_multiblock_read_count = 16
db_name = cmstst
hash_area_size = 2048000				??? need tuning ???

instance_name = cmstst
java_pool_size = 20971520
large_pool_size = 614400

log_archive_dest_1 = "location=/archlogs/cmstst"
log_archive_format = "arch%s.arc"
log_archive_start = TRUE
log_buffer = 262144					?? this log buffer
is enough??
log_checkpoint_interval = 10000				??

log_checkpoint_timeout = 1800
max_enabled_roles = 30
open_cursors = 300
optimizer_index_caching = 90
optimizer_index_cost_adj = 35
os_authent_prefix = ""
processes = 100
remote_login_passwordfile = EXCLUSIVE
session_cached_cursors = 100
shared_pool_size = 134217728
sort_area_retained_size = 262144
sort_area_size = 262144
timed_statistics = TRUE

I realy appreciate your help and assistant. I am getting confused, just want to know changing any of these parameter help the performance to reduce the number of CONSISTANT GETS or NOT???

Thanks in advance.
