Client Backup Monitoring Procedure for TSM

When administrators or users access Tivoli Storage Manager, an administrative or client node session is established with the server. The server assigns each client session a unique session number.

To request information about client sessions, enter:

query session

 

 

Sess Comm.  Sess     Wait   Bytes   Bytes Sess  Platform Client Name

Number Method State    Time    Sent   Recvd Type

 

 

3 Tcp/Ip IdleW    9 S    7.8 K     706 Admin WinNT    TOMC

 

5 Tcp/Ip IdleW    0 S    1.2 K     222 Admin AIX      GUEST

 

6 Tcp/Ip Run      0 S      117     130 Admin Mac2     MARIE

 

 

Check the wait time and session state. The wait time determines the length of time (seconds, minutes, hours) the server has been in the current state. The session state can be one of the following:

Start

Connecting with a client session.

Run

Running a client request.

End

Ending a client session.

RecvW

Waiting to receive an expected message from the client while a database transaction is in progress. A session in this state is subject to the COMMTIMEOUT limit.

SendW

Waiting for acknowledgment that the client has received a message sent by the server.

MediaW

Waiting for removable media to become available.

IdleW

Waiting for communication from the client, and a database transaction is not in progress. A session in this state is subject to the IDLETIMEOUT limit.

For example, Tivoli Storage Manager cancels the client session if the IDLETIMEOUT option is set to 30 minutes, and a user does not initiate any operations within those 30 minutes. The client session is automatically reconnected to the server when it starts to send data again.

 

 

Most commands run in the foreground, but others generate background processes. In some cases, you can specify that a process run in the foreground. Tivoli Storage Manager issues messages that provide information about the start and end of processes. In addition, you can request information about active background processes. If you know the process ID number, you can use the number to limit the search. However, if you do not know the process ID, you can display information about all background processes by entering:

query process

shows a server background process report after a DELETE FILESPACE command was issued. The report displays a process ID number, a description, and a completion status for each background process.

Process Process Description      Status                                          Number                                                                          2 DELETE FILESPACE         Deleting filespace DRIVE_D for node CLIENT1:

172 files deleted.

 

Any administrator can request general server information, most of which is defined by SET commands. To request this information, enter:

query status

 

The displayed information includes:

  • The server name
  • When the server was installed and last started
  • Whether the server is enabled or disabled
  • Whether client registration is open or closed
  • Whether passwords are required for client/server authentication
  • How long passwords are valid
  • Whether accounting records are being generated
  • How long messages remain in the activity log before being deleted
  • How many client sessions can concurrently communicate with the server
  • How many client node sessions are available for scheduled work
  • What percentage of the scheduling start-up window is randomized
  • What scheduling mode is being used
  • How frequently client nodes can poll for scheduled work
  • How many times and how often a client node can retry a failed attempt to perform a scheduled operation
  • How long event records remain in the database
  • The interval before re-authentication is required for the Web administrative client interface

 

Use the QUERY OPTION command to display information about one or more server options.

You can issue the QUERY OPTION command with no operands to display general information about all defined server options. You also can issue the QUERY OPTION command with a specific option name or pattern-matching expression to display information on one or more server options.

To display general information about all defined server options, enter:

query option You can set options by editing the server options file
