* Hardware: Dell PowerEdge 12GB ram / 2TB disco
* Versão do Oracle: 10g R2
* Sistema Operacional: CentOS 5.4
Olá, preciso de ajuda. Nunca atuei como DBA e muito menos já tinha utilizado o linux na vida. Fui orientado pela chegia a instalar um CentOS 5.4 com Oracle 10g R2.
Infelizmente não foi possível a criação de 3 servidores virtuais para cada necessidade (Desenvolvimento, Homologação e Produção). Todos os ambientes deverão ficar instalados numa mesma instância.
Consegui realizar a instalação do linux e Oracle sem problemas. Criei 03 (três) bases distintas. (Desenv, Homolg, Prod).
Ao reiniciar o servidor, faço o seguintes passos:
#lsnrctl start (sem erros)
# dbstart (também sem erros)
# sqlplus /nolog
SQL> connect system/senha@desenv
connected.
SQL> connect system/senha@homolog
connected.
[b]SQL> connect system/senha@prod
ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux-x86_64 Error: 2: No such file or directory[/b]
Segue o startup.log
