Nesta série de artigos estarei mostrando como instalar o IBM DB2 Enterprise Edition no Linux.

Atualizado para o IBM DB2 v11.1

Obs.: Outras versões foram testadas, com problemas semelhantes, que foram resolvidos com os passos abaixos.

Realizando a Instalação

Parte 1: DB2:Preparando_o_Ambiente_para_a_Instalacao - !!! Passo importante !!!

Extraindo os arquivos

No diretório onde estão o arquivo .tar.gz, faça o seguinte

Crie um diretório para descompactar

# mkdir -p /root/db2Inst
# cd /root/db2Inst

Extraia os arquivos

> tar -xvzf ../DB2_ESE_97_Linux_x86-64.tar.gz

Instalando o DB2

# cd server_ese_u

Instalação Silenciosa

# ./db2_install -b /opt/ibm/db2/V11.1 -f NOTSAMP

Instalacao

# ./db2_install

Definindo o local de instalação

Default directory for installation of products - /opt/ibm/db2/V11.1

e aguarde o final da instalação.

Criando os usuários de Administração

No meu ambiente, o espaço alocado foi montado no diretório /opt/ibm, então vou criar o diretório db2home neste diretório.

mkdir -p /opt/IBM/db2home

Criando os usuários

groupadd dasadm1
groupadd db2grp1
groupadd db2fgrp1

useradd dasusr1 -m -g dasadm1 -d /opt/IBM/db2home/dasusr1
useradd db2inst1 -m -g db2grp1 -d /opt/IBM/db2home/db2inst1
useradd db2fenc1 -m -g db2fgrp1 -d /opt/IBM/db2home/db2fenc1

passwd dasusr1
passwd db2inst1
passwd db2fenc1

Criando a instância do DB2

# cd /opt/ibm/db2/V11.1/instance/
# ./db2icrt -u db2fenc1 db2inst1
DBI1070I Program db2icrt completed successfully.

Vericando as portas configuradas no arquivo /etc/services do Linux.

# cat /etc/services

Insira as seguintes linhas:

DB2_db2inst1    50000/tcp
DB2_db2inst1_1  50001/tcp
DB2_db2inst1_2  50002/tcp
DB2_db2inst1_END        60003/tcp

Verificando a licença

# su - db2inst1 

$  db2licm -l
...

Finalizando

# su - db2inst1

$ db2 get dbm cfg
$ db2 update dbm cfg using SVCENAME DB2_db2inst1

$db2set db2comm=tcpip
$db2set DB2AUTOSTART=yes

$db2start

Pronto!!!!
