Description

Restart Servers (WWW, PC, and OCLC servers) from job_list

Resolution

This is what is in the$alephe_tab/job_list:

00 04:40:00 N                      server_monitor -tks WWW
00 04:40:20 N                      server_monitor -tks PC
00 04:40:40 N                      server_monitor -tks OCLC
00 04:41:00 Y                      VIR01 clear_vir01                    VIR01
00 04:45:00 Y                      VIR01 p_sys_01                       VIR01,WWW,
00 04:45:20 Y                      VIR01 p_sys_01                       VIR01,PC,
00 04:45:40 Y                      VIR01 p_sys_01                       VIR01,OCLC,
 

**To stop all server processes**, this is what is in the job_list:
05 01:40:00 N server_monitor -ks
05 01:50:00 N <whatever procedure you want to run with the servers down>
05 02:00:00 N /exlibris/aleph/u16_2/alephe/server_startup

"server_monitor -ks" stops all the servers, but p_sys_01 can be used to restart the WWW, PC and OCLC servers only. Thus, in the preceding, a
a server_startup script is referenced. The script would need to be modeled after the $alephe_root/aleph_startup script, which starts the servers.

server_startup would look like this:
#!/bin/csh -f
source /exlibris/aleph/u16_2/alephe/aleph_start
source $aleph_proc/def_local_env
set sav_alephver_alias = `alias alephver`
set new_alephver_alias = 'echo "xxx" > /dev/null'
alias alephver "$new_alephver_alias"
#*******************************************
# startup servers
#*******************************************.
<Insert the "startup servers" section from your $alephe_root/aleph_startup here.>
rm_f_symbol
alias alephver "$sav_alephver_alias"

Additional Information

server_monitor -pks" (as opposed to the usual "-tks") can be used to take down the server running on a particular port. (The "p" stands for port; "t" for type.) Example:

> server_monitor -pks 6991
