查看Oracle的最大并发数限制,可是查看v$license视图

 

v$license视图:

里面记录了Oracle最大的并发数以及当前用户的连接数,
官方文档有如下描述:

This view contains information about license limits.

ColumnDatatypeDescription

SESSIONS_MAX

NUMBER

Maximum number of concurrent user sessions allowed for the instance

SESSIONS_WARNING

NUMBER

Warning limit for concurrent user sessions for the instance

SESSIONS_CURRENT

NUMBER

Current number of concurrent user sessions

SESSIONS_HIGHWATER

NUMBER

Highest number of concurrent user sessions since the instance started

USERS_MAX

NUMBER

Maximum number of named users allowed for the database

 

其实,该试图中的SESSIONS_CURRENT就等于select count(*) from v$session where TYPE = 'USER'


show parameter license_max_sessions //查看最大并发数,如果是0,则默认是无限制,但如果在
在初始化文件里说明了,,就以初始化文件为主
