 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                
16                > ssh-agent | head -2 > /var/lib/pgsql/ssh-agent.env
17                > chmod 600 /var/lib/pgsql/ssh-agent.env
18                > source /var/lib/pgsql/ssh-agent.env
19                > ssh-add
20                (The password is written on my whiteboard (old production prod... passwd)) 
21                
22 production 1.1 2. Login as user production: 
23

25                > chmod 600 /var/tmp/ssh-agent.env
26                > source /var/tmp/ssh-agent.env
27                > ssh-add 
28                (The password is written on my whiteboard (old production prod... passwd))
29                NOTE: cron jobs use this /var/tmp/ssh-agent.env file
30                
31                3. Start sum_svc and related programs:

34                
35                4. Start the vncserver:
36                

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

38 production 1.1 > vncserver -geometry 1280x1024
39                
40                You will require a password to access your desktops.
41                
42                Password: production password (basically no ....)
43                Verify:
44                Would you like to enter a view-only password (y/n)? n
45                
46                New 'X' desktop is dcs0.Stanford.EDU:1
47                
48                5. Login as production on j0:
49                
50                > vncviewer
51                
52                (answer what vncserver told you, e.g. dcs0.Stanford.EDU:1)
53                
54                6. In the window that vncviewer opened do:
55                
56                > cd /home/production/cvs/JSOC/proj/datacapture/scripts>
57                > ./socdc
58
