Novell BUSINESS CONTINUITY CLUSTERING 1.1 SP1 - 9-21-2010 ADMINISTRATION GUIDE FOR OPEN ENTERPRISE SERVER 1 SP2 LINUX Administration Manual page 47

To enable a resource for business continuity, certain values (such as IP addresses, DNS names, and
tree names) specified in resource load and unload scripts need to be changed in corresponding
resources in the other clusters. You need to add the search and replace strings that are used to
transform cluster resource load and unload scripts from this cluster to another cluster.
The search and replace data you add is resource-specific, and it is not synchronized via Identity
Manager between the clusters in the business continuity cluster.
To add resource script search and replace values specific to this resource:
1 In the Resource Script Replacements section of the page, click New.
If a resource has already been configured for business continuity, you can click Edit to change
existing search and replace values or click Delete to delete them.
2 Add the desired search and replace values, then click OK.
The search and replace values you specify here apply to only to the resource you are enabling
for business continuity. If you want the search and replace values to apply to any or all cluster
resources, add them to the entire cluster instead of just to a specific resource.

If you are creating a new cluster resource, click Next, then continue with
Selecting Peer Clusters for the Resource
You can select the Use Regular Expressions check box to use wildcard characters in your search and
replace values. The following links provide information on regular expressions and wildcard
characters:

You can find additional information on regular expressions and wildcard characters by searching the
Web.
IMPORTANT: If you change the resource-specific search and replace data after inti ti ally adding
it, you must update the resource load script and unload script in one of the other clusters by editing it
and adding a space or a comment to it. This causes the script to be updated with the new search and
replace data.
You can also update the IP address on the cluster protocols page in iManager to cause IP address
search and replace values to be updated for both load and unload scripts. This might require you to
go back and change the IP addresses specified in the resource load and unload scripts in the source
cluster to their original values.
