Question

我需要获取有关连接到我的DB2的用户的信息。如何获得（如果可以）计算机名称/登录或该用户的IP？我可以获得host_name，current user并登录DB2，但我想要更具体的信息，如IP或计算机名称。我怎么能这样做？

Answer 1

您可以从MON_GET_CONNECTION表函数中获取该信息。

表函数在最后的版本中发生了很大的变化，所以它取决于你的DB2版本你可以得到什么值。

SELECT application_handle, 
       CLIENT_USERID,
       CLIENT_WRKSTNNAME, 
       CLIENT_HOSTNAME, 
       CLIENT_IPADDR
FROM TABLE(MON_GET_CONNECTION(cast(NULL as bigint), -2)) AS t 
ORDER BY rows_returned DESC;

例如，CLIENT_HOSTNAME和CLIENT_IPADDR在v9.7

中不起作用

您可以使用MetaData获取一些有用的数据。例如，以下代码：

ResultSet rS = dataSource.getConnection().getMetaData().getClientInfoProperties();
while(rS.next()){
    System.out.println("**************************************************");
    System.out.println("NAME: <" + rS.getString(1) + ">");
    System.out.println("MAX_LEN: <" + rS.getInt(2) + ">");
    System.out.println("DEFAULT_VALUE: <" + rS.getString(3) + ">");
    System.out.println("DESCRIPTION: <" + rS.getString(4) + ">");           
}
    System.out.println("**************************************************");

应该给你一些接近这个的东西：

**************************************************
NAME: ApplicationName
MAX_LEN: 255
DEFAULT_VALUE: 
DESCRIPTION: The name of the application currently utilizing the connection. This is stored in DB2 special register CURRENT CLIENT_WRKSTNNAM.
**************************************************
NAME: ClientAccountingInformation
MAX_LEN: 255
DEFAULT_VALUE: 
DESCRIPTION: The value of the accounting string from the client information that is specified for the connection. This is stored in DB2 special register CURRENT CLINT_ACTNG
**************************************************
NAME: ClientHostname
MAX_LEN: 255
DEFAULT_VALUE: ADMIN-9XYZK
DESCRIPTION: The hostname of the computer the application using the connection is running on. This is stored in DB2 special register CURRENT CLINT_WRKSTNNAM
**************************************************
NAME: ClientUser
MAX_LEN: 255
DEFAULT_VALUE: 
DESCRIPTION: The name of the user that the application using the connection is performing work for. This is stored in DB2 special register CURRENT CLINT_USRID.
**************************************************

DB_MEMBERS表函数返回有关DB2实例的基本成员信息。

db2SelectStatement = "select * from table(SYSPROC.DB_MEMBERS()) as members";

这将输出如下内容：

MEMBER_NUMBER ----------- -------------- HOST_NAME ------ PARTITION_NUMBER MEMBER_TYPE

0 ------------------------- member1.mycompany.com ---------------- 0 -------------------------- d
1 ------------------------- member2.mycompany.com ---------------- 0-- ------------------------ç
7 ------------------------- member3.mycompany.com ---------------- 0-- ------------------------ D

您可以选择以下列：

MEMBER_NUMBER
HOST_NAME
PARTITION_NUMBER
MEMBER_TYPE
PORT_NUMBER
SWITCH_NAME
STATUS

我在DB 10上测试了它并且它正在工作，但是我没有在DB 9上测试它

db2

select AGENT_ID as AGENT, 
       substr(APPL_NAME, 1, 30) as APP_NAME,
       substr(APPL_ID, 1, 40)as APP_IP_ADD,
       substr(CLIENT_NNAME, 1, 40)as CLIENT 
from sysibmadm.snapappl_info order by CLIENT_NNAME

输出

AGENT                APP_NAME                       APP_IP_ADD                               CLIENT
