 4                	Summary of starting a dcs0 or dcs1 machine after a reboot
 5                	--------------------------------------------------------
 6                
 7                NOTE:IMPORTANT: Please keep in mind that each data capture machine has its
 8                own independent /home/production and is accessed via j0.
 9                Note the SUMS database is jsocdc. This is a separate DB on each dcs.
10                
11                dcs0 = AIA
12                dcs1 = HMI
13                
14                1. Login as user postgres:

15 production 1.3 (This s/b running from the boot of the machine:
16                /usr/local/pgsql-8.4/bin/postgres -D /var/lib/pgsql/dcs1_data)

17 production 1.1 
18                > ssh-agent | head -2 > /var/lib/pgsql/ssh-agent.env
19                > chmod 600 /var/lib/pgsql/ssh-agent.env

20 production 1.3 > source /var/lib/pgsql/ssh-agent.env (NOTE: ^D if you went into csh earlier)

21 production 1.1 > ssh-add
22                (The password is written on my whiteboard (old production prod... passwd)) 
23                
24                2. Login as user production: 
25                
26                > ssh-agent | head -2 > /var/tmp/ssh-agent.env
27                > chmod 600 /var/tmp/ssh-agent.env
28                > source /var/tmp/ssh-agent.env
29                > ssh-add 
30                (The password is written on my whiteboard (old production prod... passwd))
31                NOTE: cron jobs use this /var/tmp/ssh-agent.env file
32                
33                3. Start sum_svc and related programs:
34                
35                > sum_start_dc
36                
37                4. Start the vncserver:
38                

39 production 1.2 > cd /home/production/cvs/JSOC/proj/datacapture

40 production 1.1 > vncserver -geometry 1280x1024
41                
42                You will require a password to access your desktops.
43                
44                Password: production password (basically no ....)
45                Verify:
46                Would you like to enter a view-only password (y/n)? n
47                
48                New 'X' desktop is dcs0.Stanford.EDU:1
49                
50                5. Login as production on j0:
51                
52                > vncviewer
53                
54                (answer what vncserver told you, e.g. dcs0.Stanford.EDU:1)

55 production 1.3 (password is the 'basically no data')

56 production 1.1 
57                6. In the window that vncviewer opened do:
58                
59                > cd /home/production/cvs/JSOC/proj/datacapture/scripts>
60                > ./socdc
61                
62                All you would normally do is hit "Start Instances for HMI" or AIA for
63                what datacapture machine you are on.
64                

65 production 1.2 =============================================================================
66                
67                Stopping a dcs machine:
68                -----------------------
69                
70                Hit the red "Exit" button on the VNC display of the socdc gui.

71 production 1.3 If you are not local ps and kill socdc. !!NOTE: If you
72                directly kill socdc you MUST also kill the 2 ingest_tlm processes.
