 #List any regular activities which do not run automatically and need an administrator's action.

[[DiskQuotas][/tmp and /scratch DiskQuotas]]
---+ Emergency Measures
<!--
 #List any measures that must be taken in case of some major incident, e.g. whether a mailing
 #list must be contacted or whether other services need to be shut down, etc.

---+ Installation
<!--
 #Comment here on any peculiarities of the installation, e.g. on special packages needed, special setup
 #procedures which are not obvious

---++ Grid middleware and experimental software
The worker nodes require some grid tools to be able to interact with SE (and maybe some other grid services). The grid tools are currently obtained via nfs from our central software server.  [[NodeTypeOLDNFSServer#Installation_of_the_grid_functio][Look there]] for installation instructions.

---++ Enforcing limits for user jobs

Use =/etc/security/limits.conf= to enforce some limits on number of processes and memory usage to keep the system stable, e.g.

<pre %FILESTYLE%>
# /etc/security/limits.conf
# Avoid the problem with limited stack:
* soft stack unlimited
* hard stack unlimited
* soft memlock unlimited
* hard memlock unlimited

# limits for the batch queue users
@cms soft nproc 30
@cms hard nproc 50

@cms soft rss 3000000
@cms hard rss 5000000
</pre>
