For some reason upon shutdown my Postgres server always stops and upon restart i always have to call;
pg_ctl -D /usr/local/var/usr/local/var/postgres -l /usr/local/var/postgres/server.log start
Can you help me understand what's stopping postgres starting up on its own and what an optimal set up would be? Thanks
Update: Mac, Yosemite 10.10.5 is what I'm on. I installed Postgres about a year and a half ago and it used to load on start up just fine. It was a while ago so i don't remember exactly how i installed it, but i'd imagine I did so via cmd line. Something, what exactly I'm unfortunately unaware of, must have happened to my system about 6 months ago as it was around then that it stopped auto-running on start up and that i last looked for 'how to get Postgres up and running manually', i found that start command that i listed above and I've been using it ever since every time i restart. A little late i know, but I've now decided to try to work out what's going wrong. Apologies for vagueness of detail as to what exactly lead to this happening.

I have a script that I want to execute daily, which requires an Internet connection in order to properly execute. However, my laptop (where the script resides) is not always on, and is not always connected to the Internet.
I want the script to execute at, say, 8:00am every day. However, if the computer is off or not connected to the Internet at 8:00, I want the script to execute at the next available chance.
How can I achieve this using cron, launchd or some other manager? Bonus points if the answer avoids having to fail the job every, say, 5 seconds once the computer turns back on, and until I connect to the Internet and it properly executes.
If it matters, I'm running OSX Mountain Lion.
anacron is probably your answer. It's usually installed on linuxes but is optional, and can be left off if your system administrator decided not to include it. On OS/X, it's a little more challenging, but there are pages on the internet explaining it better than I have room to here. Anacron running from launchd can be done.
On linux the man page should point you in the right direction.
Additionally you can make your script aware of the internet connection with a wget command and interrogate the results. If it's unsuccessful, go into a loop waiting for an internet connection to work with a timer of 10 minutes or whatever makes sense to you.
Hit me up if you need details of how to accomplish any of these tasks.
Anyone ever experienced something like that? I'm installing OpenCMS 8.5.0. for evaluation, running on Tomcat 7x, and during the 8th step of setup (Installing Modules), the process freezes - I've got stuck for a long time in a same line (I left it the way it was, and hung out for coffee for 30-40 minutes), without any update.
What have you done?
Thanks,
*** Edited from this line ***
I've tried to refresh the page (After coming back from my coffee break), and it only cleared the logs. So I stopped the server and re-started it again. The process started from beginning (I had to drop the database and create it again), the processes freezes again, I waited some time, a tried to refresh the page sometimes, again I faced logs inside the 'textarea' the being cleared, after some tries, the process was finally finished.
Anyone have faced the same experience?
Things to check:
How much max. heap is assigned to the Tomcat? 64MB as the default standard? Eventually tried to increase that parameter?
Can ou check the log (WEB-INF/logs/opencms.log) or the catalina.out - do you see any errors in there?
I have OpenCms 8.5 running on Tomcat7 without any problems.
Which OS are you on? Windows, Linux, Mac?
I'm having a very strange problem. I'm using dfs-datastores Pail abstraction to write data to HDFS in Java. I don't think the Pail piece is important to the problem though.
When it calls org.apache.hadoop.fs.FileSystem getFS(java.lang.String path) with a path on my local filesystem it pauses for about 2 minutes seemingly doing nothing then returns. This is on my laptop.
The weird thing is that it worked really fast when I was on the network at my office today, but now that I'm home it's doing it again. I'm running Ubuntu 10.10 64-bit with Java 1.7.
Anyone have any ideas what it's doing? What could be different between being at work and being at home?
UPDATE:
I've been stepping through code with the debugger and it seems to be having trouble in Configuration.loadResource(). It's calling that multiple times and it will take 5-10 seconds to return from that function.
UPDATE2:
I've narrowed this down a little further. The biggest hang up seems to be when it calls KerberosName.setConfiguration(). Which would explain why it runs fast at work since the Active Directory acts as a Kerberos server. I don't have one here at home, so it can't find one. Now they question is why in the world it's trying to load the Java Kerberos stuff.
I found a solution (or at least a work around). I installed the krb5-kdc package and now my little program runs fast without any unexplained pauses. After this I removed krb5-kdc, tested and it was still running fast. I removed /etc/krb5.conf and it started doing the pause again. It looks like using the Hadoop library on Ubuntu (at least) requires a /etc/krb5.conf file.
Maybe this will help someone else.
I'm getting this error message every 10 seconds.

I'm running OS X 10.6.6.
Anyone knows what the problem may be and how do solve it?
This is a situation that's been around in Unices for donkey's years. Your program is exiting immediately as soon as it is invoked, leading to it be restarted over and over by launchd. launchd has noticed this and stopped respawning the program. The standard advice on this goes back many years, too: Find out why the daemon process is immediately exiting rather than running, and fix the cause of that. (It's usually a daemon misconfiguration of some kind.)
Yes, technically, in Mac OS 10 speak this is an "agent" rather than a "daemon", but that doesn't change either the nature of the problem or what you have to do to fix it.

Quoting:
These following commands helped a lot
launchctl list -> shows a list of autostart services
launchctl remove com.webex.asassist
launchctl remove com.webex.taskwatcher
How can I find what's hanging all new installations on a Windows box?
While testing an installation script on Windows (XP Pro, if it matters) I've run into a situation wherein any and all attempts to install anything on the system hang waiting on who knows what. When the system is restarted, all queued up attempts at installation then go through their exit paths with pop-ups that report the installation is being aborted due to system shutdown having been requested. Of course, reboots do not cure the problem. The system otherwise runs fine.
So... How can I determine what part of the OS I've wedged? (Something in the registry, I suppose, but I'm a real greenhorn when it comes to Windows.) Most likely, something from a preceding install attempt went awry and is now blocking even though I saw no errors reported. Once I figure this out, I want to put in a check for this sort of thing, possibly at both ends of my install scripts, if that seems reasonable.
Thanks for your input.
UPDATE:
Unfortunately for me, rebuilding from scratch to get to the point the system's in now is about 9 hours. I'd like to unwedge it from where it is now rather than reload (again). Procmon seems great but I haven't got SP2 installed, only SP1! -frown- So, other ideas are welcome.
I assume you've tried logging the install to see where things go wrong?
Try rolling back to before things went wrong using "System Restore", if that doesn't solve it and the MSI log files show nothing useful then I'd take the plunge and reload before wasting any more time on it.
That said, if you're developing installers then taking an image of this PC in it's crappy state could be a worthwhile exercise. Some point in the future when you have more time to debug you can try and figure out what the problem is.
P.S. I'm assuming you're asking this question from the point of view of someone developing an installer and not as a tech-support question... otherwise this question should probably be closed as not-programming-related ;)
Try using Procmon to figure out where the installer is having problems, if you set a filter it will report all file and registry activity for that process.
