Recital's version of Samba allows application data to be shared and locked correctly across these systems, allowing a truly integrated heterogeneous data environment. For example Recital applications running on a UNIX/Linux server can read and update FoxPro databases residing on a Microsoft Windows NT server through the use of Samba.
You can view the modified changes by downloading the following files and patching these into your current Samba installation.
open.c (file opening and share modes)
version.h (versioning information)
The variable CPPFLAGS in the file Makefile will require the define -DRECITAL added to it.
In order to make the locking compatible between UNIX/Linux and Windows the following environment variable must be placed in the profile.db for Unix/Linux Developer and in profile.uas for the Universal Application Server:
DB_SAMBA=YES ;export DB_SAMBA 
The following settings need to be added to the smb.conf file to ensure that file names are always converted to lower case:
preserve case = no 
default case = lower 
mangle case = yes 
The following settings need to be added to the smb.conf file for locking to operate correctly:
oplocks = False
share modes = no

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:

  1. System Log
  2. Client/Server Communication Logs
  3. 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

For instructions on enabling log files for individual products, please follow these links:

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.
