Description

Compares Metrics Engine configurations and produces a dsconfig batch file needed to bring the source inline with the target.

Its uses include comparing multiple servers for configuration differences, producing a batch file to reconfigure a server from scratch from the out-of-the-box configuration, and comparing a local server against an expected configuration.

Both the source and the target configurations can be retrieved over LDAP, accessed from the local server's file system, extracted from a specific file, or retrieved from every server in a configuration server group. Also, with the exception of accessing a configuration from a specific file, the source and/or target configurations can be compared as they existed at any point in the past, including the baseline, pre-installation configuration.

Some configuration differences (those that will always differ between instances, like instance-name) are excluded by default to reduce the amount of spurious output, but these can be included by specifying the --includeExpectedDifferences command. Further differences can be excluded with the --exclude option.

This tool attempts to generate a batch file that can be applied to the source server without any errors. However, there are some edge case configurations that the tool is not sophisticated enough to handle. For example, it cannot handle two peer configuration objects that would require swapping values for a property (e.g. evaluation-order-index) that must be unique within the server. It will still generate a dsconfig batch file that includes these changes, but they might be rejected by the server. In these rare cases, the batch file can be hand edited so that it can be applied to a running server or it can be applied with the server shut down using 'dsconfig --offline'.

Examples

Compare the current configurations of server1 and server2. The changes necessary to bring server1's configuration in-line with server2 are written to the console. The same credentials are used for connecting to both servers:
config-diff --sourceHost server1 --sourceBindDN "cn=Directory Manager" \
     --sourceBindPassword password --targetHost server2


Compare the current configuration of the local server to the baseline, pre-installation configuration, ignoring any changes that could be made by the installer, and writing the output to the configuration-steps.dsconfig file. This provides a script that can be used to configure a newly installed server identically to the local server:
config-diff --sourceLocal --sourceBaseline --targetLocal \
     --exclude differs-after-install --outputFile configuration-steps.dsconfig


Determine the configuration steps necessary to undo all configuration changes that were made to the local server in the last two weeks:
config-diff --sourceLocal --targetLocal --targetDate -2w


Audit the configuration of all servers in the configuration server group against an expected configuration. The baseline, pre-installation configuration is retrieved and the dsconfig batch file, standard-config.dsconfig, is applied to it (in-memory) to establish the expected configuration. The configuration of each server in the configuration server group of server1 is then compared to this authoritative configuration, and the steps necessary to return each server to this configuration are written out to the non-compliance-config-changes/ directory. Configuration settings that differ by the Location of the server or ones that are set by the installer are ignored:
config-diff --sourceConfigGroup --targetHost server1 \
     --targetBindDN "cn=Directory Manager" --targetBindPassword password \
     --targetBaseline --targetPreDiffBatchFile standard-config.dsconfig \
     --exclude differs-by-location --exclude differs-after-install \
     --outputDir non-compliance-config-changes/
