oracle在安装dbca时，报错：ORA:04031 关于shared Memory，我应该怎么调呢

Posted 2023-02-20

说明在DBCA过程如果按照默认的shared memory分配可能不足，在DBCA中你用custome选项，不要typicl安装，指定大一些的shared memory，再试试。 参考技术A 下面是oracle的官方解释，你的共享内存设的小了，
ORA-04031: unable to allocate string bytes of shared memory ("string","string","string","string")
Cause: More shared memory is needed than was allocated in the shared pool.
Action: If the shared pool is out of memory, either use the dbms_shared_pool package to pin large packages, reduce your use of shared memory, or increase the amount of available shared memory by increasing the value of the INIT.ORA parameters "shared_pool_reserved_size" and "shared_pool_size". If the large pool is out of memory, increase the INIT.ORA parameter "large_pool_size". 参考技术B 共享内存太低，建议增加oracle sga。
如果是oracle10g，直接修改sga_maxsize和sga_target就可以了
