执行立即“查询”ORA-04030：尝试分配 56 字节时进程内存不足（调用堆，qerrmbv[]：qerrmObnd）

Posted 2023-03-27

【中文标题】执行立即“查询”ORA-04030：尝试分配 56 字节时进程内存不足（调用堆，qerrmbv[]：qerrmObnd）

【英文标题】：Execute Immediate 'Query' ORA-04030: out of process memory when trying to allocate 56 bytes (callheap,qerrmbv[]: qerrmObnd)

【发布时间】：2014-08-29 15:51:08

【问题描述】：

我正在尝试在 sqlplus 中运行一个脚本，该脚本通过“立即执行”填充一个名为“ccb_check”的表，但我得到“ORA-04030：尝试分配 56 个字节时进程内存不足（调用堆，qerrmbv [ ]: qerrmObnd)'

我需要你的帮助事实上，当我删除“立即执行”时，查询会起作用，所以我想知道有没有办法使用“立即执行”语句运行脚本。

这个查询实际上返回了超过 100 万行。

【问题讨论】：

这个查询返回多少行？

听起来您需要为 Oracle 实例分配更多内存。因此，最好在 dba.stackexchange.com 上提出这个问题。

【参考方案1】：

我看到你所有的桌子都是远程的。我认为更有效的（基于类似情况下的最后调整经验）将是在远程数据库上创建视图并仅查询必要的列。这种方法将减少发送的数据量。
