Getting hold of your replication formulas (SnTT Sunday edition)


Since R6 we are able to manipulate replication formulas using Lotus Script. You simply retrieve the entry and update or delete it. There is only one problem: If you don't know what custom replication pairs are in your database you can't do anything about it. Since "wild" custom replication formulas are a nightmare to track down I created the following script and XSLT stylesheet to extract this information using DXL. My script simply creates documents that document the settings. It will be easy to extend the script to include deletion of the entries. Or you could modifiy it to track replication formulas in multiple databases.

As usual: your mileage might vary!

This LotusScript was converted to HTML using the ls2html routine,
provided by Julian Robichaux at nsftools.com.

Here is the stylesheet I used:

<xsl:stylesheet version= "1.0" exclude-result-prefixes= "d">
<xsl:output method= "xml" version= "1.0" encoding= "UTF-8" indent= "yes" />
<xsl:template match= "/" >
<xsl:apply-templates />
</xsl:template>
<xsl:template match= "d:database" >
<xsl:element name= "database" >
<xsl:attribute name= "version" >
<xsl:value-of select= "@version" />
</xsl:attribute>
<xsl:attribute name= "maintenanceversion" >
<xsl:value-of select= "@maintenanceversion" />
</xsl:attribute>
<xsl:apply-templates select= "d:note[@class='replicationformula']" />
</xsl:element>
</xsl:template>
<xsl:template match= "d:note[@class='replicationformula']" >
<xsl:element name= "document" >
<xsl:attribute name= "form" />
<xsl:apply-templates select= "d:item[@name='$TITLE']" />
<xsl:apply-templates select= "d:item[@name='$ReplSrcServers']" />
</xsl:element>
</xsl:template>
<xsl:template match= "d:item[@name='$ReplSrcServers']" >
<xsl:element name= "item" >
<xsl:attribute name= "name" />
<xsl:copy-of select= "d:textlist" />
</xsl:element>
</xsl:template>
<xsl:template match= "d:item[@name='$TITLE']" >
<xsl:element name= "item" >
<xsl:attribute name= "name" />
<xsl:copy-of select= "d:text" />
</xsl:element>
</xsl:template>
<xsl:template match= "d:note[@default='true' and @class='replicationformula']" />
<xsl:template match= "*" />
</xsl:stylesheet>
P.S.: If anybody knows a good tool/stylesheet to transform XML source to HTML, let me know.
