Livelink^® 9.5 search index has a new configuration that organizations need to understand as part of their upgrade planning. The new approach uses partitions that allow you to divide the index into multiple segments. The primary advantage of this new approach is the ability to increase search and index performance by distributing the index across multiple index processes each with their own computing resources. A secondary advantage is that backing up and restoring the index can be faster since the files are segmented.

The use of partitions adds more complexity to architecting the search index. Open Text provides an index migration tool that will analyze your pre Livelink^® 9.5 indexes and make recommendations for memory requirements based on the number of partitions selected. You can run the tool to do the analysis and then say no when it prompts you to do the actual migration.

Below is an example output from the tool:

When architecting your Livelink^® 9.5 search index you need to consider your current index size, your estimated growth per year and your existing hardware.

Important numbers to know are:

• Partitions can only be 1 GB in size
• A partition will take up 4 GB of memory when it is full
• Partitions only store the metadata portion of the index in memory

We strongly recommend that you have an experienced Livelink^® analyst work with you to determine the optimal configuration for your index. The analyst will take into account your current configuration, your expected growth and your implementation goals to determine the optimal search index configuration for your organization.
