Não consigo mais conectar via SQL Plus*.

[holden 0]

Pessoal, bom dia. Gostaria de saber se podem me ajudar. Instalei Oracle 8i na minha máquina e, entrei a primeira vez no SQL Plus normalmente. Quando reiniciei a máquina depois e, qdo tento entrar agora dá os seguintes erros de conexão: ERROR: ORA-12203: TNS:unable to connect to destination (QUANDO NÃO INFORMO O HOST TREVISOLLI) ERROR: ORA-12514: Message 12514 not found; product=RDBMS80; facility=ORA (QUANTO INFORMO O HOST TREVISOLLI) Muito obrigado. Abraços, Trevisolli

Pessoal,Estou postando meu INIT.ORA e TNSNAMESINIT.ORA ## Copyright © 1991, 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.################################################################################ db_name = "oracle8" instance_name = oracle8 service_names = oracle8 db_files = 1024 # INITIAL# db_files = 80 # SMALL# db_files = 400 # MEDIUM# db_files = 1500 # LARGE control_files = ("C:\Oracle\oradata\oracle8\control01.ctl", "C:\Oracle\oradata\oracle8\control02.ctl", "C:\Oracle\oradata\oracle8\control03.ctl") open_cursors = 100max_enabled_roles = 30db_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 = 2048 # INITIAL# db_block_buffers = 100 # SMALL# db_block_buffers = 550 # MEDIUM# db_block_buffers = 3200 # LARGE shared_pool_size = 15728640 # INITIAL# shared_pool_size = 3500000 # SMALL# shared_pool_size = 5000000 # MEDIUM# shared_pool_size = 9000000 # LARGE large_pool_size = 614400java_pool_size = 20971520 log_checkpoint_interval = 10000log_checkpoint_timeout = 1800 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 log_buffer = 32768 # INITIAL# log_buffer = 32768 # SMALL# log_buffer = 32768 # MEDIUM# log_buffer = 163840 # LARGE #audit_trail = true # if you want auditing#timed_statistics = true # if you want timed statisticsmax_dump_file_size = 10240 # limit trace file size to 5M 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_1 = "location=C:\Oracle\oradata\oracle8\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 = ( RBS0, RBS1, RBS2, RBS3, RBS4, RBS5, RBS6 ) # 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 toglobal_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.

Seu Listner foi iniciado ??? tenta abrir uma janela DOS e digita lsnrctl start pode ser que o listner não tenha iniciado automaticamente .

ou vai no painel de controle/Ferramentas administrativas/ serviços e verifica os serviços do oracle se estão startando automaticamente...não me lembro agora mas deve ser OracleListenerService ou algo do gênerodá um zóio lah![]'s

Se os listeners estiverem no ar, corretamente, verifique lá no seu REGEDIT nas entradas doORACLE se a variável HOME está setada. Isso geralmente acontece ( entrar somente quando secoloca o service name ) por que esta variável não esta setada indicando qual a instância padrãoa se conectar quando necessário.Sds
