连接到 HANA 时解锁 liquibase 锁

Question

我是运行 VDI 上针对 SAP HANA 数据库的 liquibase 脚本。然后，VDI 挂了，所以我就杀掉了 VDI。再次打开 VDI 并尝试启动相同的应用程序运行相同的 liquibase 脚本时，出现以下错误：正在初始化与 HANA 的连接...

INFO  [2018-10-09 17:36:42,245] liquibase: Waiting for changelog lock....

.....

然后我得到以下错误

! liquibase.exception.LockException: Could not acquire change log lock.  Currently locked by SomeVMMAchine since 10/9/18 11:05 AM
! at liquibase.lockservice.StandardLockService.waitForLock(StandardLockService.java:175) ~[liquibase-core-3.4.1.jar:na]

我知道之前在 Whosebug 上回答了这个问题 (Liquibase lock - reasons?)，但是 hana 数据库人员无法按照建议在 Hana 数据库中找到名为："DATABASECHANGELOGLOCK" 的 table通过答案。有什么建议吗？

Answer 1

我的建议是：再次询问数据库人员。我会假设 table 在那里。否则 liquibase 应该如何知道它当前被 "SomeVMMAchine since 10/9/18 11:05 AM" 锁定。

你也可以尝试运行releaseLocks命令解除锁定
