Startup and Shutdown

Wiki > The Backend System > System components > Startup and Shutdown

This page shows the behaviour expected for IBEX or starting and stopping. There are two different modes in which IBEX can run:

1. Full: As the instrument control, which archiving, configruations, logging etc
2. MiniInst: As a provider of IOCs which are used by SECI

In addition to this it can be on an instrument but switched off because SECI is running.

The system will provide IOCs for SECI (2) if a file called startup.txt is in the ICP Config Root. ICP Config Root defaults to C:/Instrument/Settings/config/<COMPUTERNAME>/configurations but may be overridden in icpconfighost.txt in C:/Instrument/Settings/config.

On a system reboot IBEX should start but only if it was running when the machine was shut down. Whether IBEX was running is recorded by the contents of a file () - this will be done as part of ticket #1950. The reboot behaviour is achieved by placing start_ibex_server script in the startup directory.

Start behaviour:

• If IBEX is running and IBEX is requested to start then IBEX should restart itself (this should have minimal data loss).
• If SECI is running and IBEX is requested to start then IBEX should kill it on start and remove the file which claims it is the only running control software.
• If full IBEX is running and SECI starts it will kill IBEX using the stop IBEX server script - this ticket #1951.

Process on Start (not definitive see actual scripts)

Start is initiated from C:\Instrument\Apps\EPICS\start_ibex_server.bat. It:

1. Stop the ibex server (see below)
2. Put start file in place #1950
3. Runs ca repeater bat
   1. Kills old carepeater tasks
   2. Starts a new task in procserve
4. Runs conserver bat
   1. Stops conserver
   2. Starts a new conserver
5. If startup.txt exists in config runs start_ibex_server_mini else runs start_ibex_server_full.bat
6. [full only] update iocs db
7. [full only] start ioc log server
8. [full only] start the alarm server
9. start the gateways
10. start the procserver for the iocs (call iocstartup\procserv.bat)
11. starts proc server control (PSCTRL IOC)
12. Reload conserver
13. [full only] start the experimental database updater (ISIS\ExperimentalDatabase\master\start_expdata.bat)
14. [full only] start the block server
15. [full only] start the database server
16. [full only] start the script server (if not on an instrument)
17. [mini only] Start and enable auto start on IOC in startup.txt list

Process on Stop (not definitive see actual scripts)

Initiated from start or C:\Instrument\Apps\EPICS\stop_ibex_server.bat. It stops the following

1. Remove start file #1950
2. IOCs in startup.txt
3. Conserver
4. IOC Log Server
5. Alarm server
6. Gateway
7. Blockserver
8. Database Server
9. Script Server
10. IOCs with PID files
11. All procserve processes
12. All exes in ioc startups
