<What's New in TEXTML Server v4?>
Introducing the new generation of TEXTML Server v4.
IXIASOFT has re-architectured TEXTML Server to make it ready for the future as a flexible, robust and scalable platform.
New features included in TEXTML Server v4.2:
- Improved transaction core
Now uses state-of-the-art multiversion concurrency control. This dramatically increases transaction performance by removing all wait states generated by write transactions
- Cached document summaries
This new feature speeds up the display of the results list in the application by caching and reducing the content transmitted by the server.
- Support for XPath 2.0
It is now possible to use XPath 2.0 in the TEXTML Server Index Definition.
New features included in TEXTML Server v4:
TEXTML Server now runs on Linux OS and Windows. This implies that it is no longer a COM+ component in Windows, greatly facilitating installation and deployment.
- Fast recovery
Document base storage is now transactional from the bottom up. As a result, after an abrupt interruption, it takes less than five minutes to recover a document base. Furthermore, because of this new feature, some customers will no longer need to use the replication module, resulting in much lighter system maintenance.
- Compliant with clustering systems
Because the server can recover a document base very quickly, customers are now able to use an operating systems' clustering system (for ex. "Windows Clustering System" or "Veritas for Linux") to build a fault tolerant system.
- Custom Properties
This feature allows applications to add custom properties (Metadata) for any document. These custom properties can be accessed or modified without having to modify the document. This feature enables applications to quickly modify or retrieve specific information about the document (e.g., to update the status of a document). All custom properties are available for search. Finally, it is possible to combine custom property search criteria with document content criteria.
- Synchronous indexes
It is now possible to declare indexes synchronous or asynchronous. Synchronous indexes enable the application to instantaneously return results for documents that have just been modified (as opposed to asynchronous indexes, for which documents which have just been modified are subject to a short delay before appearing in search results).
- Grouping of search results
After a search, an application can ask the server to analyze the search result and to return the number of documents for each specified index value. This feature is useful for guiding the user in his search process and in refining his search.
- Live Backup now possible
This feature allows customers to perform backups of the document base without stopping the server or putting document bases in read-only mode. Read/Write operations are available during the backup.
- Better performance and scalability
This version offers better overall performance because of improved parallelism in core server operations.
- Better file management
TEXTML Server now uses its own, new storage system, rather than using the OS file system to store documents. With version 3.x, it was difficult to copy or backup a document base because there were potentially millions of files to copy now the system only has to copy a few files. This new feature is extremely useful for maintenance (and appreciated by IT admin teams!).
- Improved indexes and support for international character sets
Customers may now choose to make indexes case sensitive or accent sensitive (making indexes language-aware), providing greater flexibility. Word breaking continues to use standard separators like spaces, commas, colons, semi colons, etc.
- New index for the Lock property
It was not possible to search "locked" (checked-out) documents in previous versions of TEXTML Server. This new version allows users to search documents which have a Lock status.
- Transfer tool for migration from v.3.6 to v.4
IXIASOFT provides a tool that automatically transfers all the content from a v3.6 document base to a v4.
