The length value of 2^31 is left shifted by 1 at instruction n54n, resulting in a negative array size for the jitNewArray call. The implementation of StringUTF16.toBytes(char[],int,int), however, has checks on the len argument that decide whether to throw NegativeArraySizeException or ...

【12c】扩展数据类型(Extended Data Types)-- MAX_STRING_SIZE 在12c中,与早期版本相比,诸如VARCHAR2, NAVARCHAR2以及 RAW这些数据类型的大小会从4K以及2K字节扩展至32K字节。只要可能,扩展字符的大小会降低对LOB 数据类型的使用。为了启用扩展字符大小,你必须将MAX_STRING_SIZE的初始数据库参数设置为EXTENDED。
参数MAX_STRING_SIZE控制扩展数据类型extended data type的最大长度: STANDARD 代表12c之前的长度限制,即varchar2、nvarchar2 4000 bytes, raw 是2000 bytes EXTENDED 代表12c 32k strings新特性,varchar2、nvarchar2、raw最大长度32k bytes Extended character data types 扩展字符类型存在以下的限制: ...
