SYSID 来指定当前system

今天用s.log遇到一个问题没办法显示log了，老提示off 这个log不能使用。

研究了一下，原因是我想看一下当前的system，于是想当然的sysid，结果发现没用，于是用sysid off,然后还是没用，再返回来就发现log这个地方悲剧了。

其实我真正想用的是sysname这个命令，可以显示当前的name，这样可以和userid一起显示

后来看了一下帮助，才知道sysid是有这个命令的，格式如下：

COMMAND INPUT ===>                                                   
                                                                     
    Purpose:  Specifies which of the system's logical                
        SYSLOG data sets is displayed on the SYSLOG panel.           
        You must be authorized to use this command.                  
                                                                     
    Where used:  Affects only the SYSLOG panel, but can be           
        entered from any SDSF panel.                                 
                                                                     
    Format:  SYSID (system-id)                                       
                   (*)                                               
                   (?)                                               
                                                                     
    Example:  SYSID IPO1                                             
        Causes the SYSLOG panel to display the SYSLOG for member IPO1.

这个可以在ds的环境中看另外一个system的log，比如下面的sysid 就可以看到所有的system

COMMAND INPUT ===> SYSID S35                                  SCROLL ===> CSR
JES SYSIDS=S30,S31,(S34),S35
