How to update while a SERVICE is installed / running?

Hello all,

how do I have to handle an installed and (possibly) runnig background service,
when I install an update over it?

Is STOPping that service sufficient or does I also have to REMOVE this service,
then, at the end of the installation, re-install and re-start it?

My idea is this:

at that begin of the installation process I check for the service to run:

For being installed
Set Variable %SERVICE_IS_INSTALLED% to FUNCTION:Check Service ("MyServer") [Is Installed]

For also running:
Set Variable %SERVICE_IS_RUNNING% to FUNCTION:Check Service ("MyServer") [Is Running]

Now:
If %SERVICE_IS_INSTALLED% Equals "1" Then
If %SERVICE_IS_RUNNING% Equals "1" Then
Run Command Line ("SC STOP MyServer") [Wait] [Show or not]
END
Run Command Line ("SC QUIT KiKSOAPServer") [Wait] [Show]
END

... now do a lot of fiddlefaddle ...

and finally at the end of the script, in the [ Execute Programs ]-section,
restoer the service according to the values from the top:

If %SERVICE_IS_INSTALLED% Equals "1" Then ! it WAS installed when we entered this process
Run Command Line ("x:\MyServer.EXE /iss") [Wait] [Show or not]
END


If %SERVICE_IS_RUNNING% Equals "1" Then ! it WAS also running when we entered this process
Run Command Line ("SC START MyServer") [Wait] [Show or not]
END

Now the state of the service should be restored to the same conditions at
starttime of the update-install.

Is that a possible way to handle the installation over an installed / running service?

Thanks in advance!

Hi Wolfgang,

What about using the built-in "Edit Service..." script function to stop and
restart the service?

Detect an installed service. If it is installed and running, stop the
service (give it a few seconds to close down, check again if it is running),
then replace the service file(s) and restart it.

Seems simpler, have not seen these (I think)

Is STOP and and RESTART sufficient? No need to REMOVE?

The process of running a service is a Windows OS thing, the installation is one
thing on its own by SB, so its independent. When the service is stopped, then
SB can stop the EXE from running, replace that file with the new version,
restart the EXE and _then_ advise the OS restart that service again, which is
actually the new EXE. This Services.MSC does not care, if an EXE is replaced,
while that service is stopped? Because Service.MSC does nothing more than
watching a list of services.

An INSTALL SERVICE puts an EXE onto that list.
A START SERVICE - well, yes, starts it, but can do only, if is was set onto the
list before.
A STOP SERVICE - aehh, well, aehh, yes - stops it. However, the EXE is still
running, because I can see it in the TaskManager. But SB takes care of that. SB
removes the running EXE, replaces it with the new from the installer, runs this
new EXE and then issues a START, which is nothing but telling the OS to
activate this EXE as a service again. Services.MSC looks on its list, sees my
EXE been listed and says "Oh yeah, the EXE is known to me, its running, lets
make it a service again!"

Is my impression correct?

Like

LOOP ! with no limits or with some iterations
Set Variable %SERVICE_IS_RUNNING% to FUNCTION:Check Service ("MyService") [Is Running]
SET counter
IF %SERVICE_IS_RUNNING% = 0 ! then its not running anymore
BREAK LOOP
ELSE
some counter eval to issue a break, before the morning dawns
END
END

If I choose iterations, how many do you suggets? Is it based on
(milli/hundreths-)Seconds or just a raw number?

Number of Iterations
[in] Executes Number of Iterations times.
This can be a numeric constant, a compiler
variable or a runtime variable. Leave this
field empty if you wish the Loop to run
continuously. In such cases, you plan to
Break Loop based on some condition you
expect to always happen.

So, how fast is one LOOP-cycle, how long does it take between two cycles of a loop?


Sounds reasonable and actually what I wanted to achive. There are actually too
many options to pick from the right hand menu! <g>

Ach, und wo ich grade dabei bin, ist meine Mail letzte Woche durchgekommen?

Probably best not to remove. If it was installed with specific
credentials, you'd want those credentials to remain intact.

check for in-use files too. Sometimes it can end up in a hung state.

STOPping the service is enough to overwrite the exe. It terminates the
service EXE but leaves it in the service list.

Thats what I thought. But short and concise! See my other post, were I wrote
exact these with lengthy blabla.

Looking at the timestamp of your post, it took me more than 30 minute to mangle
my thoughts out of my brain.

Thanks, Arnor!

If you're going to use SB to do your service stuff, why not use the
built-in service stuff instead of the commandline?

Also, you could write a support DLL that uses SelfService to do that
stuff for you in Clarion code.
