ORA-02854: Invalid number of request buffers
Cause: The value given for “db_slave_buffers” in your INIT.ORA file is less than 0.
Action: Use a number that is greater than or equal to 0.
ORA-02854:非法请求缓冲区数(Invalid number of request buffers)是一个 Oracle 数据库的错误代码。
ORA-2854 异常提示请求缓冲区数不正确,其大小至少为1。填入的值小于1,亦即会产生该错误。
当在控制文件中设置了参数_cache_message_buffers小于1时,将会报ORA-02854错误。
1. 检查_cache_message_buffers参数值是否小于1,若小于1则需要修改
2. 修改_cache_message_buffers参数值为大于等于1,重新启动数据库即可
