本文深入探讨了在Solaris操作系统环境下，尝试增加Oracle数据库连接数量时遇到的ORA-07252和ORA-00600错误，并提供了解决方案。主要涉及Unix内核参数SEMMNS的调整，以允许数据库启动时拥有更高的进程参数，从而解决并发连接受限的问题。

本文参考自：

Trying to Increase the Number of Database Connections (Doc ID 167674.1)

fact: Oracle Server - Enterprise Edition 8
fact: Solaris Operating System (SPARC)
symptom: Trying to Increase the Number of Database Connections
symptom: ORA-07252 spcre: semget error, could not allocate semaphores
symptom: ORA-00600: internal error code, arguments: [skgmbusy]
symptom: svr4 error 28 no space left on device
cause: Unix kernel not configured correctly for the number of processes trying to connect to the database.

fix:

Increase the unix kernel parameter SEMMNS to a higher value. This will allow the database to started with a higher processes parameter.
