Question

How often do you restart Windchill services?

I'm guessing most will agree that it is not practical to leave Windchill services running forever. As a preventative measure, do you restart Windchill on a regular basis? How often? Daily, Weekly, Monthly, Only if there is a problem?

For comparison, here are our stats:

75 CAD users, 25 non-CAD users

Server architecture: Sun Solaris

Restart Frequency: Monthly, or if there is a problem

We have experienced more issues with hung method servers lately and are forced to kill or restart. I’m wondering if this preventative approach is helpful for others. Please share any thoughts or experiences on this topic.

We use Windchill one week, then SmartTeam the next - and let Windchill rest every other week. Just kidding of course...

How do keep from restarting during backup - do you do hot backup?

We do bi-weekly cold backups. So, obviously we stop all the services during
that time.
Sometimes we end up restarting the services in between due to some problem
or the other.

We do hot backups (exports) on the DB nightly, hourly exports of the local ldap and vault data is stored on a redundant array. If Windchill method servers were not locking up, we would have no need to restart services other than for upgrades and maintenance.

If I missed this I am sorry, but what Version and datecode are you running?

We restart only once a month for Windows patching.

We do weekly restart on our Windows 32 bit Windchill application server with 9.1 M040 installed.

Windchill PDMLink 9.1 M050 running on Solaris 10
Shutdown nightly for backup as follows:
1. shutdown Windchill (including Oracle)
2. zfs snapshot
3. restart Windchill
4. backup the zfs snapshot

So total downtime is about 2-3 minutes.

We run 9.0 M080 on windows 32 bit. We restart windchill, Tomcat & Apache
after clearing the tomcat and windchill cache every week. It runs great
without a restart for 2 or 3 weeks but we do not want to take a chance.

Windchill 9.1 M020 running on Solaris 10
Runs until I have to load a patch. Server and DB on Netapp filer which handles hourly, nightly and weekly snapshots. Backups occur on weekends but they are hot backups. MethodServer may restart itself but system is running for weeks.

At the end of the day it depends on the situation, if you face any issue or
the server is slow may be restart can help you out there.

I have seen many companies be successful with nightly cold, incremental backups where the three main services are stopped (windchill, tomcat and apache) and full cold backups on the weekends. If they have partners overseas using Windchill or in different time zone it can be tricky getting a scenario that includes a solid, nightly cold backup within the small time frame but usually there is a solution.
