+==== Start ====
+:TODO: Translation
+Das Starten des Clusters. Für die Clusterkommunikation wird auf allen Clusterknoten ein unix2webd-Prozess gestartet, zu beachten ist ggf eine Freischaltung des verwendeten Ports in der jeweiligen Firewall der Clusterknoten.
+=== SLES ===
+Das SCript-CLuster ist so konfiguriert, dass es beim nächsten Reboot des Rechners automatisch gestartet wird. Die Konfiguration des SCript-CLusters (siehe voriges Kapitel) muss vor dem Start des Clusters erfolgen.
+Manuelles Starten über:
+  # /etc/init.d/sccl_cluster reload
+  Config File: /etc/unix2web/sccl.conf
+  Config File: /etc/unix2web/sccl.conf
+  /usr/local/bin/unix2webd -D -p 3579 -h /usr/local/sccl/bin  -r "SCCL Administration" -E -t 300 -U -sp "/usr/local/sccl/bin/u2w_pwd.dat" -or " 10.1.3.113 10.1.3.113"
+Dies muss auf jedem Clusterknoten erfolgen. Die Konfigurationsdateien sollten dafür auf allen Clusterknoten gleich sein.

+==== Commands ====
+=== sccl_disable ===
+=== sccl_disable_node ===
+=== sccl_dist_config ===
+  sccl_dist_config [-m] [-x <excludenode>] [-n <onlynode>] [files ...]
+Distribute the cluster-relvant files to all other nodes.
+Normally, you do not specify any files explicitly.
+  sccl_dist_config
+Mainly the files:
+  etc/sccl/sccl.conf
+  etc/sccl/adminpwd.dat
+  etc/sccl/userpwd.dat
+  etc/sccl/packages.conf
+  etc/sccl/resources.conf
+  etc/sccl/scripts/
+These files will overwrite any existing files on the destination nodes:!:
+Special action: define <other_node> also as master.
+  sccl_dist_config -m -n <other_node>
+Remember: only a master node can add more nodes
+-----
+=== sccl_enable ===
+=== sccl_enable_node ===
+=== sccl_get_aktnode ===
+Find the active cluster node(s) for a cluster package.
+  $ sccl_get_aktnode <package>
+  { [<node1> [<node2>]...] | 0 }
+All names of all cluster nodes are listet, on which the <package> is active.
+If the <package> is not active on any cluster node, the output is:
+<file>
+</file>
+Example:
+  $ sccl_get_aktnode package3
+  clnode1 clnode2
+The package package3 is active on the cluster nodes clnode1 and clnode2.

+==== Examples ====
+=== Example 1 ===
+This example script-cluster configuration describes a productive environment
+of:
+  * two servers, host001 and host002
+    * one application server
+    * one database server
+  * each server has a package
+    * 'tomcat' for the application server
+    * 'database' for the database server
+This is a very simple example and does not contain any failover functionality.
+The following configuration files only show the significantly changed parts or parameters.
+<code bash /etc/sccl/sccl.conf>
+# Clustername
+CLUSTER=SAMPLE01
+# Cluster nodes
+NODES="host001 host002"
+</code>
-==== Example ====
+The package 'tomcat' can only run on host 'host001'.
+The package 'database' can only run on host 'host002'.
+<code bash /etc/sccl/packages.conf>
+# <package>  [-]  <host1> [<host2> [<host3>]...]
+# Application
+tomcat host001
-# Datenbank
+# Database
-oracle Oracle PRG:startstop_oracle RST:tomcat:CLUSTER
+database host002
+</code>
-# Applikation
-tomcat Tomcat CPKG:oracle:WAIT:3 PRG:startstop_tomcat
+<code bash /etc/sccl/resources.conf>
+# <package>  <package_name>  <resource1> [<resource2> [<resource3]...]
-Oder
+database My_Database   PRG:db_startstop   RST:tomcat:CLUSTER
+tomcat Tomcat_Application_Server   CPKG:database:WAIT:3   PRG:tomcat_startstop
+</code>
-# Datenbank
+Alternatively you can use:
-oracle Oracle PRG:startstop_oracle RST:tomcat:CLUSTER
-# Applikation
+<code bash /etc/sccl/resources.conf>
-tomcat Tomcat CPKG:oracle:START PRG:startstop_tomcat
+# <package>  <package_name>  <resource1> [<resource2> [<resource3]...]
+database My_Database   PRG:db_startstop   RST:tomcat:CLUSTER
+tomcat Tomcat_Application_Server   CPKG:database:START   PRG:tomcat_startstop
+</code>
