IBM Sterling: Configurando o DB2 como Container no OpenShift

= Procedimento =

Realizando o Deploy do DB2
1) Crie um novo projeto no OpenShift para o DB2 e defina contas de serviço e permissões.

oc new-project sterling-b2bi-db2

oc create serviceaccount sterling-b2bi-db2-sa oc adm policy add-scc-to-user privileged -n sterling-b2bi-db2 -z sterling-b2bi-db2-sa

2) Crie o arquivo db2-deploy.yaml para deploy do DB2 no openshift

apiVersion: v1 kind: Service metadata: name: sterling-b2bi-db2-lb spec: selector: app: db2 type: LoadBalancer ports: - protocol: TCP port: 50000 targetPort: 50000 --- apiVersion: apps/v1 kind: StatefulSet metadata: name: db2 spec: selector: matchLabels: app: db2 serviceName: sterling-b2bi-db2-lb replicas: 1 template: metadata: labels: app: db2 spec: serviceAccount: sterling-b2bi-db2-sa containers: - name: db2 securityContext: privileged: true image: ibmcom/db2 env: - name: LICENSE value: accept - name: DB2INSTANCE value: db2inst1 - name: DB2INST1_PASSWORD value: db2inst1 ports: - containerPort: 50000 name: db2 imagePullPolicy: IfNotPresent volumeMounts: - mountPath: /database name: sterling-b2bi-db2-storage volumeClaimTemplates: - metadata: name: sterling-b2bi-db2-storage spec: accessModes: - ReadWriteOnce resources: requests: storage: 20Gi storageClassName: ibmc-block-gold

3) Realize o deploy

oc create -f db2-deploy.yaml

Verifique até ficar no status Running.

oc get pods NAME   READY   STATUS    RESTARTS   AGE db2-0  1/1     Running   0          31m

Espere até ver esta linha como a última entrada no log. Ctrl+C para interromper os logs.

oc logs -f db2-0 ...  /database/config/db2inst1/sqllib/ctrl/db2strst.lck

Criando a database para o SB2BI
From inside the Db2 container, create B2BIDB database for B2Bi.

1) Conectar ao pod de banco de dados.

oc rsh pod/db2-0

2) Criando a database

su - db2inst1

cat <> create_b2bi_db.sql CREATE DATABASE B2BIDB AUTOMATIC STORAGE YES USING CODESET UTF-8 TERRITORY DEFAULT COLLATE USING SYSTEM PAGESIZE 32768; CONNECT TO B2BIDB; UPDATE DATABASE CONFIG FOR B2BIDB USING LOGFILSIZ 65536; UPDATE DATABASE CONFIG FOR B2BIDB USING LOGPRIMARY 40; UPDATE DATABASE CONFIG FOR B2BIDB USING NUM_LOG_SPAN 32; UPDATE DATABASE CONFIG FOR B2BIDB USING AUTO_MAINT ON; UPDATE DATABASE CONFIG FOR B2BIDB USING AUTO_TBL_MAINT ON; UPDATE DATABASE CONFIG FOR B2BIDB USING AUTO_RUNSTATS ON; UPDATE DATABASE CONFIG FOR B2BIDB USING AUTO_REORG ON; UPDATE DATABASE CONFIG FOR B2BIDB USING AUTO_DB_BACKUP ON; CREATE USER TEMPORARY TABLESPACE B2BUSERTEMP PAGESIZE 32K BUFFERPOOL IBMDEFAULTBP; CREATE BUFFERPOOL B2BIDB_04KBP IMMEDIATE SIZE 1000 PAGESIZE 4K; CREATE REGULAR TABLESPACE TS_REG04_B2BIDB PAGESIZE 4K BUFFERPOOL B2BIDB_04KBP; CREATE BUFFERPOOL B2BIDB_08KBP IMMEDIATE SIZE 1000 PAGESIZE 8K; CREATE REGULAR TABLESPACE TS_REG08_B2BIDB PAGESIZE 8K BUFFERPOOL B2BIDB_08KBP; CREATE BUFFERPOOL B2BIDB_16KBP IMMEDIATE SIZE 1000 PAGESIZE 16K; CREATE REGULAR TABLESPACE TS_REG16_B2BIDB PAGESIZE 16K BUFFERPOOL B2BIDB_16KBP; CONNECT RESET; EOF

[db2inst1@db2-0 ~]$ db2 -stvf create_b2bi_db.sql

[db2inst1@db2-0 ~]$ db2 list database directory ...    Database alias                       = B2BIDB Database name                       = B2BIDB Local database directory            = /database/data [db2inst1@db2-0 ~]$ exit sh-4.2# exit

3) Teste a conectividade db2 de fora. Use DbVisualizer para testar a conectividade de fora. Identifique o endereço IP do LoadBalancer (porta 50000). Parâmetro EXTERNAL-IP

oc get svc NAME                 TYPE           CLUSTER-IP      EXTERNAL-IP        PORT(S)           AGE sterling-b2bi-db2-lb LoadBalancer   172.xx.xx.250   169.xx.xx.83   50000:30707/TCP   43m
