| - | ====== OACOMP Environment Compiler ====== | ||
| - | ===== Overview ===== | ||
| - | OACOMP is a console based application that compiles a file of Omnidex environment source statements into a Compiled Omnidex Environment or an XML Omnidex Environment that can then be connected via the Omnidex SQL CONNECT Statement. | ||
| - | |||
| - | As of Omnidex Version 5.0, Omnidex supports two types of Omnidex Enviroments: | ||
| - | |||
| - | - Compiled Omnidex Environments | ||
| - | - XML Omnidex Environments | ||
| - | |||
| - | Either type of Omnidex Environment can then be subsequently accessed via the Omnidex SQL CONNECT statement or via an ODBC or JDBC connection. | ||
| - | |||
| - | Compiled Omnidex Environments can be directly used by DBINSTAL. However XML Omnidex Environments can only be maintained by OdxAdmin or maintained using OdxSQL with Omnidex DDL statements such as CREATE ENVIRONMENT and CREATE TABLE. | ||
| - | |||
| - | ===== Running OACOMP ===== | ||
| - | |||
| - | OACOMP requires an Omnidex Environment Source file. | ||
| - | |||
| - | oacomp [ Options ] Source_Filespec | ||
| - | [ Object_Filespec.env ] | [XML_Filespec.xml ] | ||
| - | [ List_Filespec ] | ||
| - | |||
| - | Source File is the uncompiled environment source detailing the database, tables and columns, and other pertinent information used by Omnidex. A .src extension is assumed and will automatically be appended to the end of the supplied file name. | ||
| - | |||
| - | Object File is the name of the output file, the compiled environment catalog. If omitted, the output file will be the same as the source file with a .env extension. | ||
| - | |||
| - | List File is an optional message file where OACOMP messages will be written. If omitted, messages will be displayed to the console. | ||
| - | |||
| - | ===== OACOMP Examples ===== | ||
| - | == Default File Suffixes == | ||
| - | |||
| - | os> oacomp myenv | ||
| - | |||
| - | Compiles myenv.src into myenv.env. Since no file suffix or a named compiled environment file is specified, myenv.src and myenv.env will be used as defaults by OACOMP. | ||
| - | |||
| - | == Specified Environment Filespec == | ||
| - | |||
| - | os> oacomp myenv.src myenv.env | ||
| - | |||
| - | Compiles myenv.src into myenv.env. Note that when the environment suffix is specified, then the source file suffix must be specified as well. | ||
| - | |||
| - | == Translates an Environment Source into an Environment XML file == | ||
| - | os> oacomp myenv.src myenv.xml | ||
| - | |||
| - | ===== OACOMP Options ===== | ||
| - | |||
| - | == xml == | ||
| - | |||
| - | Creates an XML Omnidex Environment from an existing Environment Source file. | ||
| - | |||
| - | os> oacomp -xml myenv | ||
| - | |||
| - | Creates a myenv.xml file from the myenv.src file. | ||
| - | |||
| - | == nostats == | ||
| - | |||
| - | Suppresses the display of the OACOMP statistics. | ||
| - | |||
| - | os> oacomp -nostats myenv | ||
| - | |||
| - | |||
| - | ===== OaComp Operation ===== | ||
| - | |||
| - | This operation occurs in three phases: | ||
| - | |||
| - | * The parsing phase checks the source file for valid syntax. | ||
| - | * The validation phase checks for unresolved references. | ||
| - | * The compilation phase creates and writes out the physical Environment Catalog. | ||
| - | |||
| - | os> oacomp <Source File> <Object File> [<List File>] | ||
| - | |||
| - | |||
| - | |||
| - | |||
| - | ===== Running OACOMP ===== | ||
| - | |||
| - | Run OACOMP from the command line with the environment source file as an argument. | ||
| - | |||
| - | If passing the source file by itself, taking the default output file, do not include the .src suffix. | ||
| - | |||
| - | If passing the source file and the output file, include both the .src suffix for the source file and the .env suffix for the output file. | ||
