Part01-基础概念与理论知识

1.1 YashanDB作业告警概念

YashanDB作业告警是指当数据库中的作业（如批处理、备份、维护等）执行出现异常或达到阈值时，系统自动发出的通知机制。作业告警是数据库运维管理的重要组成部分，能够帮助运维人员及时发现和解决作业执行过程中的问题，确保数据库系统的稳定运行。

YashanDB作业告警的特点：

实时性：及时发现作业执行异常
自动化：自动发出告警通知
可配置性：灵活配置告警规则和阈值
多渠道：支持多种告警通知方式
可扩展性：支持与监控系统集成

1.2 YashanDB作业告警类型

YashanDB作业告警主要包括以下类型：

作业失败告警：当作业执行失败时发出的告警
作业超时告警：当作业执行时间超过设定阈值时发出的告警
作业延迟告警：当作业开始执行时间延迟超过设定阈值时发出的告警
作业资源使用告警：当作业资源使用超过设定阈值时发出的告警
作业依赖告警：当作业依赖的其他作业执行失败时发出的告警

1.3 YashanDB作业告警优势

YashanDB作业告警的主要优势包括：

及时发现问题：快速发现作业执行过程中的问题
减少人工干预：自动化告警，减少人工监控的工作量
提高系统可靠性：及时处理问题，提高系统的可靠性
优化作业执行：通过告警信息优化作业执行策略
降低运维成本：减少人工监控和故障处理的成本

风哥提示：作业告警是YashanDB数据库运维管理的重要组成部分，合理配置作业告警可以显著提高系统的可靠性和运维效率。学习交流加群风哥微信: itpux-com

Part02-生产环境规划与建议

2.1 YashanDB作业告警规划

YashanDB作业告警规划要点：

# 需求分析
– 作业类型：分析需要监控的作业类型
– 告警需求：确定需要的告警类型和级别
– 通知方式：选择合适的告警通知方式
– 响应流程：制定告警响应流程

# 告警策略规划
– 告警级别：设置不同级别的告警（紧急、重要、一般）
– 告警阈值：根据作业特性设置合理的阈值
– 告警频率：控制告警的频率，避免告警风暴
– 告警抑制：设置合理的告警抑制规则

# 通知渠道规划
– 邮件通知：配置邮件告警通知
– 短信通知：配置短信告警通知
– 微信通知：配置微信告警通知
– 监控系统集成：与监控系统集成

# 响应流程规划
– 告警接收：指定告警接收人员
– 告警处理：制定告警处理流程
– 告警升级：设置告警升级机制
– 告警记录：记录告警处理过程

2.2 YashanDB作业告警策略

YashanDB作业告警策略建议：

# 告警级别策略
– 紧急：需要立即处理的严重问题（如数据库备份失败）
– 重要：需要及时处理的问题（如作业执行超时）
– 一般：需要关注的问题（如作业执行延迟）

# 告警阈值策略
– 作业执行时间：根据历史执行时间设置阈值
– 作业资源使用：根据系统资源情况设置阈值
– 作业成功率：设置作业成功率的最低阈值
– 作业依赖：设置作业依赖的检查规则

# 告警通知策略
– 紧急告警：多渠道通知（邮件+短信+微信）
– 重要告警：邮件+短信通知
– 一般告警：邮件通知

# 告警处理策略
– 紧急告警：立即处理，24小时响应
– 重要告警：工作时间内处理
– 一般告警：定期处理

2.3 YashanDB作业告警考虑

YashanDB作业告警考虑：

系统负载：告警配置不应增加系统负载
告警频率：避免过多的告警导致告警疲劳
告警准确性：确保告警的准确性和可靠性
告警响应：建立有效的告警响应机制
告警集成：与现有监控系统集成

生产环境建议：在规划作业告警时，需要根据企业的实际情况和业务需求进行合理设计，确保告警的有效性和可操作性。学习交流加群风哥QQ113257174

Part03-生产环境项目实施方案

3.1 YashanDB作业告警配置

3.1.1 YashanDB作业告警基本配置

— 步骤1：创建作业告警配置表
CREATE TABLE fgedu.job_alert_config (
alert_id NUMBER(10) PRIMARY KEY,
job_name VARCHAR2(100) NOT NULL,
alert_type VARCHAR2(50) NOT NULL,
alert_level VARCHAR2(20) NOT NULL,
threshold NUMBER(10,2),
notify_channels VARCHAR2(200),
enabled VARCHAR2(1) DEFAULT ‘Y’,
create_time TIMESTAMP DEFAULT SYSTIMESTAMP,
update_time TIMESTAMP DEFAULT SYSTIMESTAMP
);

— 步骤2：插入告警配置
INSERT INTO fgedu.job_alert_config (alert_id, job_name, alert_type, alert_level, threshold, notify_channels)
VALUES (1, ‘backup_job’, ‘FAILURE’, ‘EMERGENCY’, NULL, ‘EMAIL,SMS,WECHAT’);

INSERT INTO fgedu.job_alert_config (alert_id, job_name, alert_type, alert_level, threshold, notify_channels)
VALUES (2, ‘etl_job’, ‘TIMEOUT’, ‘IMPORTANT’, 3600, ‘EMAIL,SMS’);

INSERT INTO fgedu.job_alert_config (alert_id, job_name, alert_type, alert_level, threshold, notify_channels)
VALUES (3, ‘report_job’, ‘DELAY’, ‘GENERAL’, 1800, ‘EMAIL’);

COMMIT;

— 步骤3：创建作业告警日志表
CREATE TABLE fgedu.job_alert_log (
log_id NUMBER(10) PRIMARY KEY,
alert_id NUMBER(10) REFERENCES fgedu.job_alert_config(alert_id),
job_name VARCHAR2(100) NOT NULL,
alert_type VARCHAR2(50) NOT NULL,
alert_level VARCHAR2(20) NOT NULL,
alert_message VARCHAR2(500) NOT NULL,
notify_status VARCHAR2(20) DEFAULT ‘PENDING’,
create_time TIMESTAMP DEFAULT SYSTIMESTAMP,

) VALUES (
v_log_id, v_alert_id, p_job_name, p_alert_type, p_alert_level, p_alert_message
);

— 发送告警通知（这里只是示例，实际需要根据通知渠道实现）
DBMS_OUTPUT.PUT_LINE(‘Sending alert for job ‘ || p_job_name || ‘: ‘ || p_alert_message);
DBMS_OUTPUT.PUT_LINE(‘Notification channels: ‘ || v_notify_channels);

— 更新通知状态
UPDATE fgedu.job_alert_log
SET notify_status = ‘SENT’,
notify_time = SYSTIMESTAMP

COMMIT;
EXCEPTION
WHEN NO_DATA_FOUND THEN
DBMS_OUTPUT.PUT_LINE(‘No alert configuration found for job ‘ || p_job_name);
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE(‘Error sending alert: ‘ || SQLERRM);
ROLLBACK;
END;
/

— 步骤5：创建作业监控触发器
CREATE OR REPLACE TRIGGER fgedu.job_completion_trigger
AFTER INSERT ON dba_scheduler_job_run_details
FOR EACH ROW
DECLARE
v_alert_message VARCHAR2(500);
BEGIN
— 检查作业执行状态
IF :NEW.status = ‘FAILED’ THEN
v_alert_message := ‘Job ‘ || :NEW.job_name || ‘ failed with error: ‘ || :NEW.error#;
fgedu.send_job_alert(
p_job_name => :NEW.job_name,
p_alert_type => ‘FAILURE’,
p_alert_level => ‘EMERGENCY’,
p_alert_message => v_alert_message
);
ELSIF :NEW.run_duration > INTERVAL ‘1’ HOUR THEN
v_alert_message := ‘Job ‘ || :NEW.job_name || ‘ completed but took ‘ ||
EXTRACT(HOUR FROM :NEW.run_duration) || ‘ hours ‘ ||
EXTRACT(MINUTE FROM :NEW.run_duration) || ‘ minutes’;
fgedu.send_job_alert(
p_job_name => :NEW.job_name,
p_alert_type => ‘TIMEOUT’,
p_alert_level => ‘IMPORTANT’,
