# # Copyright (c) 1991, 1997, 1998 by Oracle Corporation # ############################################################################## # Example INIT.ORA file # # This file is provided by Oracle Corporation to help you customize # your RDBMS installation for your site. Important system parameters # are discussed, and example settings given. # # Some parameter settings are generic to any size installation. # For parameters that require different values in different size # installations, three scenarios have been provided: SMALL, MEDIUM # and LARGE. Any parameter that needs to be tuned according to # installation size will have three settings, each one commented # according to installation size. # # Use the following table to approximate the SGA size needed for the # three scenarious provided in this file: # # -------Installation/Database Size------ # SMALL MEDIUM LARGE # Block 2K 4500K 6800K 17000K # Size 4K 5500K 8800K 21000K # # To set up a database that multiple instances will be using, place # all instance-specific parameters in one file, and then have all # of these files point to a master file using the IFILE command. # This way, when you change a public # parameter, it will automatically change on all instances. This is # necessary, since all instances must run with the same value for many # parameters. For example, if you choose to use private rollback segments, # these must be specified in different files, but since all gc_* # parameters must be the same on all instances, they should be in one file. # # INSTRUCTIONS: Edit this file and the other INIT files it calls for # your site, either by using the values provided here or by providing # your own. Then place an IFILE= line into each instance-specific # INIT file that points at this file. # # NOTE: Parameter values suggested in this file are based on conservative # estimates for computer memory availability. You should adjust values upward # for modern machines. # # You may also consider using Database Configuration Assistant tool (DBCA) # to create INIT file and to size your initial set of tablespaces based # on the user input. # ############################################################################### # replace "%AVAILABLE_SID%" with your database name #db_name=%AVAILABLE_SID% db_name=orcl92 db_files = 80 # INITIAL # db_files = 80 # SMALL # db_files = 400 # MEDIUM # db_files = 1500 # LARGE control_files = ("C:\oracle\oradata\orcl92\control1.ctl","C:\oracle\oradata\orcl92\control2.ctl") db_file_multiblock_read_count = 8 # INITIAL # db_file_multiblock_read_count = 8 # SMALL # db_file_multiblock_read_count = 16 # MEDIUM # db_file_multiblock_read_count = 32 # LARGE db_block_buffers = 1000 # INITIAL # db_block_buffers = 100 # SMALL # db_block_buffers = 550 # MEDIUM # db_block_buffers = 3200 # LARGE shared_pool_size = 10000000 # INITIAL # shared_pool_size = 3500000 # SMALL # shared_pool_size = 5000000 # MEDIUM # shared_pool_size = 9000000 # LARGE log_checkpoint_interval = 10000 log_checkpoint_timeout = 0 processes = 59 # INITIAL # processes = 50 # SMALL # processes = 100 # MEDIUM # processes = 200 # LARGE parallel_max_servers = 5 # SMALL # parallel_max_servers = 4 x (number of CPUs) # MEDIUM # parallel_max_servers = 4 x (number of CPUs) # LARGE dml_locks = 200 log_buffer = 8192 # INITIAL # log_buffer = 32768 # SMALL # log_buffer = 32768 # MEDIUM # log_buffer = 163840 # LARGE # sequence_cache_entries made obsolete # sequence_cache_entries = 10 # INITIAL # sequence_cache_entries = 10 # SMALL # sequence_cache_entries = 30 # MEDIUM # sequence_cache_entries = 100 # LARGE # sequence_cache_hash_buckets made obsolete # sequence_cache_hash_buckets = 10 # INITIAL # sequence_cache_hash_buckets = 10 # SMALL # sequence_cache_hash_buckets = 23 # MEDIUM # sequence_cache_hash_buckets = 89 # LARGE # audit_trail = true # if you want auditing # timed_statistics = true # if you want timed statistics max_dump_file_size = 10240 # limit trace file size to 5 Meg each # Uncommenting the line below will cause automatic archiving if archiving has # been enabled using ALTER DATABASE ARCHIVELOG. # log_archive_start = true # log_archive_dest = %ORACLE_HOME%\database\%%ORACLE_SID%%\archive # log_archive_format = "%%%ORACLE_SID%%%T%TS%S.ARC" # If using private rollback segments, place lines of the following # form in each of your instance-specific init.ora files: # rollback_segments = (r01, r02, r03, r04) # UNDO Segument undo_management = AUTO undo_tablespace = undotbs # If using public rollback segments, define how many # rollback segments each instance will pick up, using the formula # # of rollback segments = transactions / transactions_per_rollback_segment # In this example each instance will grab 40/5 = 8: # transactions = 40 # transactions_per_rollback_segment = 5 # Global Naming -- enforce that a dblink has same name as the db it connects to global_names = TRUE # Edit and uncomment the following line to provide the suffix that will be # appended to the db_name parameter (separated with a dot) and stored as the # global database name when a database is created.
