For systems that do not have the xterm libraries installed, please install these to use xterm, or set the DB_TERM environment variable to start Recital from a terminal:
DB_TERM=gnome-terminal; export DB_TERM
This setting can be added to the /opt/recital/conf/recital.conf (text) file to make it available system-wide.
Please note that the Recital ODBC Driver for Linux requires a 32 bit ODBC Driver Manager.

Yes, your FoxPlus and FoxPRO applications should run under Recital with little to no changes at all. We provide expert product support if you have any questions or problems. If you lack the resources to move your applications into Recital we can provide that service to you also if required.
All temporary files created by Recital are stored in the directory specified by the environment variable DB_TMPDIR.
mkdir /opt/recital/tmp
mount -t tmpfs -o size=1g recitaltmpfs /usr/recital/tmp
I am pleased to finally report that the Centos release of Redhats 5.3 has been built and is available for download from http://www.centos.org/
The highlights of this release can be found at the following URL: http://www.redhat.com
The main areas of interest in my opinion excluding critical secirty fixes are:
- Updated hardwaresupport support for the new Intel Core i7 (Nehalem) chips
- Beefed up virtualiseation support increasing CPU and Ram limits of Virtual machines.
- Inclusion of the fully open sourced OpenJDK. This makes Red Hat Enterprise Linux 5.3 the first enterprise-ready solution with a fully open source Java stack when combined with JBoss Enterprise Application Platform.
For those who already have Centos 5.2 installed you can simply receive the update via Yum.
Before you do the following, check that you do not have 3rd party repo's and the Centos-testing repo enabled.
You can display the currently enabled repo's using the following command.
$ yum repolist
Then as root at the prompt type:
$ yum update

This article talks about the log files available in Recital products and how to enable logging when required.
Overview
When discussing a problem with the Recital Support Team, one of the most common requests is that you enable logging and send them the log files produced. Log files along with error files are designed to provide detailed information about Recital processes and the prevailing environment and can be a fast-track to resolving a problem.
Log Files
There are three main types of log file:
- System Log
- Client/Server Communication Logs
- Custom Logs
System Log
The System log is a system-wide all product log. It tracks all login and logout operations from either Recital or the Recital Server. Logout details include the exit code: 0 for an error-free, 'normal' exit and the error number and message when an error has occurred. It also shows the licenses that have been loaded and any license error codes and messages. The system log filename is recital.log.
Client/Server Communication Logs
The Client/Server communication logs track the requests and responses between the Recital Server and its clients. The log files are as follows:
| Filename | Type | Description |
|---|---|---|
|
dbserver.log |
System-wide |
The Recital Server startup log. This logs any problems with the Recital Server startup. |
|
port.log |
System-wide |
The port listener log. The port listener (or portserver) listens on port 8001 for client connection requests and spawns the appropriate server process. |
|
net.log |
Connection |
The netserver log. The netserver is the Recital Server database and 4GL engine. |
|
rsi.log |
Connection |
The Recital Server Interface (RSI) Gateway log. This logs communication with the Database Gateways to SQL databases. |
|
rec.log |
Connection |
The Recital Database Gateway log. The Recital Database Gateway (or recserver) is the SQL database engine for Recital Gateway data access. |
|
mys.log |
Connection |
The MySQL Database Gateway log. |
|
ora.log |
Connection |
The Oracle Database Gateway log. |
|
inf.log |
Connection |
The Informix Database Gateway log. |
|
ing.log |
Connection |
The Ingres Database Gateway log. |
|
pos.log |
Connection |
The PostgreSQL Database Gateway log. |
|
jdb.log |
Connection |
The JDBC Driver Database Gateway log. |
Custom Logs
The Recital/4GL USERLOG() function can be used to log information to a user-specific log file for debugging or audit trail purposes. For full information on this function, please see the USERLOG() documentation.

Enabling Log Files: Recital Server for Linux
To enable the system log file for the Recital Server for Linux, include the following command in the conf/config.db file:
set syslogging on
To set up Client/Server logging, the Recital Server can be started with the 'logging' parameter, in which case, all relevant logging will take place.
# service startup logging<
Alternatively, one or more of the following environment variables can be added to the dbserver.conf file or set at the Operating System prompt. The Recital Server must be restarted before environment variable changes will be recognized. Each environment variable should be set to the name of a log file.
Environment Variable

In Brief
- Log files provide important information to aid problem resolution, but they are also an overhead, so logging should only be enabled when required, not in normal production operation.
- The System log provides a system-wide view of logins, exits and error codes.
- The System log can be viewed in table format via the SYSLOGGING System Table.
- The System log is enabled using the SET SYSLOGGING ON Recital/4GL command in the conf/config.db file.
- Client/Server logs provide detailed information on client/server requests and responses.
- Client/Server logs are enabled using environment variables, symbols or Registry entries or by specifying the 'logging' parameter when starting the Recital Server.
- The location of log files is determined by the DB_LOGDIR setting.
- Versioning of log files is determined by the DB_LOGVER setting.
SET DATADIR TO [ <directory> ]This command is used to specify a directory where database tables, memos, indexes, and dictionary files are located. When a table is being opened this directory is searched first before the current directory and the file search path to locate the table and its associated files. This allows the database tables to be relocated to a different file system without the need to change an existing application.
