无法在 ActiveIQ Unified Manager 9.7 中生成数据库备份

适用于

ActiveIQ Unified Manager 9.7 （所有平台）

问题

在数据库备份失败期间，将观察以下一个或多个操作。

• 从“管理 / 数据库备份”视图中的计划触发时，不会存在任何数据库备份。
• 服务器日志（ ocumserver.log ）在执行刷新查询时会报告到 MySQL 的连接失败。

2020-03-11 09:41:40,587 ERROR [oncommand] [taskScheduler-1] [Backup|ScheduleBackup] [c.n.d.i.b.MySqlDumpBackupManager] Error occured while taking mysql dump. Error message: 2020-03-11 09:41:40,587 ERROR [oncommand] [taskScheduler-1] [Backup|ScheduleBackup] [c.n.d.i.b.MySqlDumpBackupManager] mysqldump: Couldn't execute 'FLUSH /*!40101 LOCAL */ TABLES': Lost connection to MySQL server during query (2013) 2020-03-11 09:41:40,602 INFO [oncommand] [taskScheduler-1] [Backup|ScheduleBackup] [c.n.d.i.b.MySqlDumpBackupManager] Deleted BackupFileInfo entity in DB 2020-03-11 09:41:40,738 ERROR [oncommand] [taskScheduler-1] [Backup|ScheduleBackup] [c.n.d.impl.backup.BackupScheduleJob] Error occurred in Regular Backup Job: com.netapp.dfm.impl.backup.BackupCreationException: Failed to create database backup using mysql utility. at deployment.dfm-app.war//com.netapp.dfm.impl.backup.MySqlDumpBackupManager.collectMysqlDump(MySqlDumpBackupManager.java:722) [[TRUNCATED]]

• 服务器日志（ ocumserver.log ）还将报告使用不同线程的内存耗尽情况，这与上面显示的 MySQL 查询失败相同。

2020-03-11 09:31:05,431 INFO [oncommand] [Thread-248] [c.n.i.s.OpmThreadPoolExecutorMonitor$ResourceMonitor] The total amount of memory used is greater than 80%
