♣ 题目部分 在Oracle中,如何解决ORA-04030和ORA-04031错误? ♣ 答案部分 ORA-04030和ORA-04031都是典型的内存分配错误,下面分别讲解。...(一)ORA-04030错误 ORA-04030报错形如“ORA-04030 'out of process memory when trying to allocate %s bytes (%s,%s...在多线程服务器(共享服务器)中,UGA被分配在SGA中,所以在这种配置下UGA不是造成ORA-04030错误的原因。因此,ORA-04030表示进程需要更多内存(堆栈、UGA或PGA)来执行其任务。...如果发生了ORA-04030错误,那么会在告警日志中记录详细信息。若发生ORA-04030错误,则可以从以下几个方面去排查该错误: ① 是否仍然有足够的可用内存?...在这些情况下,在出现错误ORA-04030之前,进程将会运行一段时间,所以,可以在这段时间内找出内存分配的位置和原因。
前言 今天巡检遇到数据库报错 ORA-04030 错误,错误日志如下: ORA-04030: out of process memory when trying to allocate 169040...bytes (pga heap,kgh stack) ORA-04030: out of process memory when trying to allocate 432 bytes (kxs-heap-c...,kprbalo temp memory) 关键词:ORA-04030、(pga heap,kgh stack)、(kxs-heap-c,kprbalo temp memory)。...3 查询MOS文档 PLSQL Procedure Causing ORA-04030: (pga heap,control file i/o buffer) And ORA-04030: (koh-kghu...sessi,pmuccst: adt/record) or ORA-04030: (koh-kghucall ,pmucalm coll) Errors (Doc ID 1325100.1) 二、解决方案
