1.通过SQLPlus修改Oracle的sessions和processes的关系是:sessions=1.1*processes + 5使用sys,以sysdba权限登录:SQLgt; show

1.通过SQLPlus修改Oracle的sessions和processes的关系是:

sessions=1.1*processes + 5

使用sys,以sysdba权限登录:

SQL> show parameter processes;

NAME TYPE VALUE--------

aq_tm_processes integer 1db_writer_processes integer 1

job_queue_processes integer 10

log_archive_max_processes integer 1

processes integer 150

SQL> alter system set

processes=400 scope = spfile;系统已更改。

SQL> show parameter processes;NAME TYPE

VALUE--------------------------------

aq_tm_processes

integer 1db_writer_processes integer 1

job_queue_processes integer 10

log_archive_max_processes integer 1

processes integer 150

SQL> create pfile from spfile;

注:sessions是个派生值,由processes的值决定,公式sessions=1.1*process + 5】

2.通过修改oracle配置文件进行修改修改SPFILEORCL.ORA文件中的processes的值。8.1.5中是init.ora文件,,在9i中修改init.ora文件是无效的,这个文件由于是一个二进制的文件,不能直接使用notepad此类的编辑器打开。否则会报错误ORA-27101 Shared memory realm does not exist。使用UltraEdit或者EditPlus之类的可以编辑二进制文件的编辑器打开此文件(直接编辑二进制文件),然后在Windows服务中重新启动Oracle服务器即可。

3.通过Oracle Enterprise Manager Console在图形化管理器中修改

a.以系统管理员的身份登入

b.进入数据库的例程-配置-一般信息-所有初始化参数

c.修改processes的值
