第 32 章 进程实例迁移

流程

1. 从 Red Hat Process Automation Manager 7.13 的 Software Downloads 页面中下载 rhpam-7.13.5-add-ons.zip 文件。
2. 提取 rhpam-7.13.5-add-ons.zip 文件。
3. 提取 rhpam-7.13.5-process-migration-service.zip 文件。

4. 输入以下命令来创建数据库表。将 <user > 替换为您的用户名，& lt;host > 替换为本地主机的名称：

   $ psql -U <user> -h <host> -d rhpam7 -f ~/process-migration/ddl-scripts/postgres/postgresql-quartz-schema.sql
   $ psql -U <user> -h <host> -d rhpam7 -f ~/process-migration/ddl-scripts/postgres/postgresql-pim-schema.sql

   Copy to Clipboard Toggle word wrap
5. 将目录更改为 process-migration 目录。

6. 使用文本编辑器，使用以下内容创建 servers.yaml 配置文件，并保存在 process-migration 目录中。在本例中，将 &lt ;user_name& gt ; 和 <password > 替换为要登录到 KieServer 的凭证。

   kieservers:
     - host: http://localhost:8080/kie-server/services/rest/server
       username: <user_name>
       password: <password>

   Copy to Clipboard Toggle word wrap

7. 使用文本编辑器创建 数据源.yaml 配置文件，并保存在 process-migration 目录中。在本例中，将 &lt ;user_name& gt ; 和 <password > 替换为要登录到数据库的凭证：

   quarkus:
     datasource:
       db-kind: postgresql
       jdbc:
         url: jdbc:postgresql://localhost:5432/rhpam7
       username: <user_name>
       password: <password>

   Copy to Clipboard Toggle word wrap

8. 重建 quarkus-run.jar 文件，使其包含 PostgreSQL 驱动程序：

   $ java -jar -Dquarkus.launch.rebuild=true -Dquarkus.datasource.db-kind=postgresql quarkus-app/quarkus-run.jar

   Copy to Clipboard Toggle word wrap

   这个命令的输出应类似以下示例：

   INFO [io.qua.dep.QuarkusAugmentor] (main) Quarkus augmentation completed in 2657ms

9. 运行 quarkus-app JAR 文件：

   $ java -jar -Dquarkus.http.port=8090 -Dquarkus.config.locations=servers.yaml,datasource.yaml quarkus-app/quarkus-run.jar

   Copy to Clipboard Toggle word wrap

   这个命令返回类似以下示例的输出：
