在客户端为什么总会更新这种表，这张表TXC_UNDO_LOG 是干什么用的？用着用着就会出现这个问题

Start from the TXC_UNDO_LOG INSERT shown in the exception and trace where this table is written in the transaction flow. Reproduce the read-only database failure and determine the table's purpose and why the client updates it. Done means the cause and an actionable resolution are documented.
