Deploying software applications efficiently requires careful consideration of system architecture and compatibility, especially when dealing with legacy systems or specific software versions like Xentry 2016 32 Bit. Ensuring all necessary components are correctly installed is crucial for optimal performance. This guide, drawing upon the principles of software engine deployment, outlines the essential files and considerations for deploying applications, particularly in environments where 32-bit compatibility, as might be relevant to systems running Xentry 2016 32 bit, is a key factor.
When deploying applications, it’s imperative to include the correct data files and executable components. These files are the backbone of the software, enabling it to function as intended. Let’s delve into the types of files required, referencing the structure and needs commonly encountered in software deployments, which can be analogously applied to ensure compatibility even for systems potentially running applications like Xentry 2016 32 bit on older architectures.
Essential Data Files for Software Deployment
Data files are critical for configuring and customizing software behavior. These files often include language settings, rules for processing data, and external resources that the application relies on. Here’s a breakdown of common data files and their purposes:
| File | Purpose |
|---|---|
| default.abc | Custom alphabet file (optional) for specialized character handling. |
| thesaur.xml | Custom user thesaurus (optional) for enhanced search and data interpretation. |
| stemming.dat | English stemming rules (optional – needed if you want to apply stemming to English text). Crucial for linguistic accuracy in text processing. |
| noise.dat | English noise word list (optional – needed for creating indexes that ignore common noise words). Improves search relevance by filtering out insignificant words. |
| WordNet data files | WordNet thesaurus for synonym searching (optional), expanding search capabilities through semantic understanding. |
| CMAP files | Encoding information to aid text extraction from Chinese, Japanese, or Korean documents lacking Unicode, essential for global character set support. |
| homedir.xml | Configuration file (optional) specifying locations for WordNet, CMAP, and ICU data files, centralizing resource management. |
| icuconfig.xml | Configuration file (optional) defining ICU libraries to load, important for internationalization features. |
These data files should typically be placed in the same directory as the application’s executable file. A recommended deployment strategy involves deploying the entire contents of a designated “data” folder along with a homedir.xml file to specify the data folder’s location. If international character support is needed, particularly for systems that might process data in multiple languages, including ICU integration and its configuration via icuconfig.xml is essential. For applications intended for systems that might handle linguistic analysis, like those dealing with documentation or search functionalities, including stemming rules and noise word lists becomes pertinent. Similarly, for applications requiring advanced search features, the WordNet thesaurus can significantly enhance synonym searching capabilities.
Windows Executable Files – 32-bit (x86)
For applications designed to run on 32-bit Windows systems, which might be the environment for older software versions or specific hardware configurations, deploying the correct 32-bit executable files is paramount. This is particularly relevant when considering compatibility with systems that might have been standard around the Xentry 2016 32 bit era. Here are the essential 32-bit Windows executable files:
| File | Purpose |
|---|---|
| dten600.dll | Core 32-bit software engine. |
| dtSearchNetStdApi.dll | .NET Standard API, necessary for applications using the .NET Standard API framework. |
| dtSearchNetApi4.dll | .NET API for .NET Framework 4.0 and later, required for C#, VB.NET, and other VS.NET applications. |
| dtSearch.Spider4.dll | .NET Spider API for .NET 4.0, specifically for .NET applications indexing websites using spider classes. |
| dtsjava.dll | Java JNI API, needed for Java-based applications to interface with the engine. |
| dtSearchEngine.jar | Java class interface, essential for Java application integration. |
| viewersdtv_ifilter.dll | External file parser to enable IFilter usage, extending file format support. |
| viewersdtv_rar.dll | External file parser to enable parsing of RAR archives, important for handling compressed files. |
| viewersdtv_pdfcrypto.dll | External file parser to enable parsing of encrypted PDF files, with considerations for export regulations. |
| dts_svr.exe | Localhost-only HTTP server, used for browser-based access to content in specific setups. |
| lbvprot.dll | Component to implement PDF hit highlighting without HTTP, enhancing PDF search within applications. |
| icu*.dll, icuconfig.xml | ICU components for internationalization, including configuration file. |
These 32-bit components are designed for x86 architectures and should be deployed in the same directory as the main application executable. For applications utilizing .NET frameworks, the dtSearchNetApi4.dll or dtSearchNetStdApi.dll are crucial, depending on the .NET version. Java applications require dtsjava.dll and dtSearchEngine.jar for proper integration. The “viewers” subdirectory houses external file parsers that extend the application’s ability to handle various file formats, including RAR archives and encrypted PDFs. The inclusion of ICU components supports applications needing internationalization and Unicode handling, which is often important in diverse software environments.
Windows Executable Files – 64-bit (x64)
For modern 64-bit Windows operating systems, deploying 64-bit components is essential to leverage the full capabilities of the hardware and operating system. While 32-bit systems and applications like Xentry 2016 32 bit might still be in use, 64-bit architecture is the current standard for performance and memory management. The 64-bit components are typically installed in a designated bin64 folder within the software’s directory structure.
| File | Purpose |
|---|---|
| dtengine64.dll | Core 64-bit software engine. |
| dtSearchNetStdApi.dll | .NET Standard API, for applications using .NET Standard. |
| dtSearchNetApi4.dll | .NET API for .NET 4.0+, for VS.NET applications. |
| dtSearch.Spider4.dll | .NET Spider API for .NET 4.0, for web indexing in .NET applications. |
| dtsjava.dll | Java JNI API for dtengine64.dll, for 64-bit Java applications. |
| viewersdtv_rar64.dll | 64-bit external file parser for RAR archives. |
| viewersdtv_pdfcrypto64.dll | 64-bit external file parser for encrypted PDF files. |
| icu*.dll, icuconfig.xml | ICU components and configuration for 64-bit systems. |
The 64-bit executables mirror their 32-bit counterparts in functionality but are compiled for the 64-bit architecture to improve performance and memory access. It’s crucial to ensure that 64-bit applications are deployed with these 64-bit components to avoid compatibility issues and to maximize efficiency.
Considerations for UWP, Linux, and macOS
Beyond Windows, software deployment often needs to cater to other operating systems. Universal Windows Platform (UWP), Linux, and macOS each have specific component requirements.
For UWP applications, separate 32-bit and 64-bit components are available, similar to traditional Windows applications, but packaged for the UWP environment.
Linux deployments require 64-bit and 32-bit shared object libraries (.so files) and Java components, along with ICU and file parser libraries compiled for Linux.
macOS deployments primarily use 64-bit dynamic libraries (.dylib files), Java components, and ICU libraries tailored for macOS.
Each platform’s specific components ensure that the software engine can operate correctly within its respective environment, handling system calls and resource management according to the OS conventions.
Licensing, External Parsers, and Encryption
Licensing terms generally permit the distribution of the listed binary and data components along with applications incorporating the software engine. However, it’s important to review the specific license agreement for any restrictions or third-party notices.
External file parsers, such as dtv_rar.dll and dtv_ifilter.dll (and their 64-bit and Linux equivalents), should be placed in a “viewers” subdirectory within the software engine’s home directory. This structured approach helps in organizing and locating these plugin components.
Encryption support, particularly for PDF files, is a significant feature. Components like dtv_pdfcrypto.dll and dtv_pdfcrypto64.dll enable the parsing of encrypted PDF files, supporting various encryption standards beyond basic 40-bit RC4. Export regulations may apply to these encryption-enabled components, necessitating legal consultation for developers exporting applications that include these features.
Windows Version Compatibility and Virtual Servers
Compatibility with various Windows versions is broad, with support extending from Windows XP SP3 (32-bit) up to the latest Windows Server and client versions. Both 32-bit and 64-bit Windows are supported, and the engine itself comes in both 32-bit and 64-bit flavors. Starting with certain versions, the 64-bit engine may require the Microsoft Universal CRT, which is generally included in modern Windows versions or available via Windows Update.
Deployment in virtualized environments like Azure or Amazon instances is also supported, provided the instance runs a compatible Windows operating system and has a file system accessible to Windows. Indexes can be stored in any file system visible to Windows, offering flexibility in storage management.
WordNet and CMAP Files
WordNet and CMAP files are optional but valuable data sets. WordNet enhances synonym searching, while CMAP files improve text extraction from Chinese, Japanese, and Korean PDF documents. These files are typically placed in WordNet and cmap subdirectories within the software engine’s home directory, respectively. Their inclusion depends on the specific features and language support requirements of the deployed application.
