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.

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.
If when your attempt to create device meta-data fails this is drbd preventing you from corrupting a file system present on the target partition.
$ drbdadm create-md drbd0
v08 Magic number not found
md_offset 30005817344
al_offset 30005784576
bm_offset 30004867072
Found ext2 filesystem which uses 190804004 kB
current configuration leaves usable 29301628 kB
Device size would be truncated, which
would corrupt data and result in
'access beyond end of device' errors.
You need to either
* use external meta data (recommended)
* shrink that filesystem first
* zero out the device (destroy the filesystem)
Operation refused.
Command 'drbdmeta /dev/drbd0 v08 /dev/sda4 internal create-md' terminated with exit code 40
drbdadm aborting
Once you have confirmed that the file system present on the target partition is no longer required at the prompt type the following:
Replace /dev/sdaX with the block device you are targeting.
dd if=/dev/zero of=/dev/sdaX bs=1M count=128
Once this has completed the drbdadm create-md drbd0 command will complete with a "success."

After split brain has been detected, one node will always have the resource in a StandAlone connection state. The other might either also be in the StandAlone state (if both nodes detected the split brain simultaneously), or in WFConnection (if the peer tore down the connection before the other node had a chance to detect split brain).
At this point, unless you configured DRBD to automatically recover from split brain, you must manually intervene by selecting one node whose modifications will be discarded (this node is referred to as the split brain victim). This intervention is made with the following commands:
# drbdadm secondary resource
# drbdadm disconnect resource
# drbdadm -- --discard-my-data connect resource
On the other node (the split brain survivor), if its connection state is also StandAlone, you would enter:
# drbdadm connect resource
You may omit this step if the node is already in the WFConnection state; it will then reconnect automatically.
If all else fails and the machines are still in a split-brain condition then on the secondary (backup) machine issue:
drbdadm invalidate resource

- Butter
- it is a dairy product made by churning fresh or fermented cream or milk. It is generally used as a spread and a condiment, as well as in cooking applications such as baking, sauce making, and frying. Butter consists of butterfat, water and milk proteins.
- Dairy milk
- is an opaque white liquid produced by the mammary glands of mammals (including monotremes). It provides the primary source of nutrition for newborn mammals before they are able to digest other types of food.

This article discusses the features in Recital that allow data to be imported and exported between platforms in Microsoft® ADO XML Format.
Overview
Extensible Markup Language, XML, is widely regarded as a lingua franca for the interchange of data. XML's text-based, platform-independent format and its integration of data and the schema to define and describe that data, make it the ideal import/export medium. Recital software provides the functionality to output the data from Recital - and other supported table formats such as FoxPro and FoxBASE - into XML file format and to import XML data into those tables' formats. Such import/export operations provide the means to exchange data with third-party applications and can also facilitate the transfer of data between Recital installations on binary-incompatible platforms.
The features examined in this article are available in Recital Terminal Developer and in the Recital Mirage and Recital Database Servers on all Recital supported platforms. Both the Recital/4GL and Recital/SQL provide XML import and export capabilities. The XML files discussed are in Microsoft® ADO XML format.
Microsoft® ActiveX® Data Objects XML Format
The ADO XML format is primarily designed for ADO Recordset persistence and ADO XML files created by Recital can be used in this way and loaded directly into ADO Recordsets. The format can, though also be used for more generic data transfer. An ADO XML file is self-contained, consisting of two sections: a schema section followed by a data section. The schema conforms to the W3C XML-Data specification and defines the data structure.
For additional information on the Microsoft® ActiveX® Data Objects XML Format, please see Appendix 1.
NOTE: The Recital XMLFORMAT setting should always be in its default setting of ADO for ADO XML Format operations.
set xmlformat to ADO
SQL
Recital/SQL offers the ability to export data into XML files using the SELECT and FETCH statements and import from XML using the CREATE TABLE and INSERT statements.
SQL: Exporting
The SELECT...SAVE AS XML statement allows the complete result set from a SELECT statement to be saved as an XML file. This could be a complete table:
open database southwind SELECT * from orders SAVE AS XML orders.xml
or a more complex multi-table query:
open database southwind
SELECT orders.orderid, orders.customerid,;
employees.employeeid, employees.lastname, employees.firstname,;
orders.orderdate, orders.freight, orders.requireddate,;
orders.shippeddate, orders.shipvia, orders.shipname,;
orders.shipaddress, orders.shipcity,;
orders.shipregion, orders.shippostalcode, orders.shipcountry,;
customers.companyname, customers.address, customers.city,;
customers.region, customers.postalcode, customers.country;
FROM orders INNER JOIN customers;
ON customers.customerid = orders.customerid,;
orders INNER JOIN employees;
ON orders.employeeid = employees.employeeid;
SAVE AS XML orderinfo
The resulting XML file can then be further processed within the same or a different Recital environment or transferred to a third party product.

Fig 1: Microsoft® Office Excel 2003: orderinfo.xml.
For data accessed through a Recital Database Gateway, such as Oracle, MySQL or PostgreSQL, the FETCH command can be used to save a cursor results set into an XML file:
// Connect to MySQL Database 'mydata' via Recital Database Gateway
nStatHand=SQLSTRINGCONNECT("mys@mysql1:user1/pass1-mydata",.T.)
if nStatHand < 1
dialog box [Could not connect]
else
DECLARE cursor1 CURSOR FOR;
SELECT account_no, last_name, first_name FROM example
OPEN cursor1
FETCH cursor1 INTO XML exa1.xml
SQLDISCONNECT(nStatHand)
endif
SQL: Importing
The CREATE TABLE statement allows a new table to be created based on the structure defined in an XML file. The data from the XML file can optionally be loaded into this new table if the LOAD keyword is included. For example, a new 'orderinfo' table can be created and populated with data from the orderinfo.xml file created by the SELECT...SAVE AS XML statement shown earlier:
open database southwind
SELECT orders.orderid, orders.customerid,;
employees.employeeid, employees.lastname, employees.firstname,;
orders.orderdate, orders.freight, orders.requireddate,;
orders.shippeddate, orders.shipvia, orders.shipname,;
orders.shipaddress, orders.shipcity,;
orders.shipregion, orders.shippostalcode, orders.shipcountry,;
customers.companyname, customers.address, customers.city,;
customers.region, customers.postalcode, customers.country;
FROM orders INNER JOIN customers;
ON customers.customerid = orders.customerid,;
orders INNER JOIN employees;
ON orders.employeeid = employees.employeeid;
SAVE AS XML orderinfo
CREATE TABLE orderinfo FROM XML orderinfo LOAD
The INSERT statement can be used to load data when the table structure already exists. Taking our earlier orderinfo.xml file again, the data can be loaded using INSERT:
open database southwind;
SELECT orders.orderid, orders.customerid,;
employees.employeeid, employees.lastname, employees.firstname,;
orders.orderdate, orders.freight, orders.requireddate,;
orders.shippeddate, orders.shipvia, orders.shipname,;
orders.shipaddress, orders.shipcity,;;
orders.shipregion, orders.shippostalcode, orders.shipcountry,;
customers.companyname, customers.address, customers.city,;
customers.region, customers.postalcode, customers.country;
FROM orders INNER JOIN customers;
ON customers.customerid = orders.customerid,;
orders INNER JOIN employees;
ON orders.employeeid = employees.employeeid;
SAVE AS XML orderinfo
CREATE TABLE orderinfo FROM XML orderinfo
INSERT INTO orderinfo FROM XML orderinfo
The examples above show the export and import in a single piece of code. To transfer data between binary-incompatible platforms, the export phase using SELECT...SAVE AS XML would be carried out on the source platform, the resulting XML file would be transferred to the target platform, then the import phase using CREATE TABLE...LOAD or CREATE TABLE + INSERT would be run on the target platform.
Recital/4GL
The Recital/4GL offers the ability to export data into XML files using the COPY TO ... TYPE XML command and import from XML using the XMLFIRST() and XMLNEXT() functions.
Recital/4GL: Exporting
The COPY TO command can be used to export data from Recital and other natively supported tables out to a wide range of formats. This includes exporting to an XML file. The '.xml' file extension is added automatically. The COPY TO command can be used to export an entire table:
open database southwind use orders copy to orders type xml
or, using the FIELDS clause and the FOR or WHILE clauses, restrict the field list and export only those records which match a particular condition:
open database southwind use orders copy to orders type xml fields orderid for year(orderdate) = 1996
Only the orderid field from those records which match the condition is exported:
<x-ml xmlns:z="#RowsetSchema" xmlns:rs="urn:schemas-microsoft-com:rowset" xmlns:dt="uuid:C2F41010-65B3-11d1-A29F-00AA00C14882" xmlns:s="uuid:BDC6E3F0-6DA3-11d1-A2A3- 00AA00C14882"> <s:schema id="RowsetSchema"> <s:elementtype rs:updatable="true" content="eltOnly" name="row"> <s:attributetype rs:basecolumn="ORDERID" rs:basetable="ORDERS" rs:write="true" rs:nullable="true" rs:number="1" name="ORDERID"> <s:datatype rs:fixedlength="true" rs:precision="10" rs:scale="0" dt:maxlength="10" rs:dbtype="numeric" dt:type="number"> </s:datatype></s:attributetype> </s:elementtype> </s:schema> <rs:data> <z:row orderid="10248"> <z:row orderid="10249"> <z:row orderid="10250"> <z:row ...
Recital/4GL: Importing
Data from an XML file can be extracted one record at a time using the XMLFIRST() and XMLNEXT() functions. XMLFIRST() reads the first record from an XML file and loads information from the file into a series of memory variables and arrays. The record data is loaded into a one-dimensional array which is created automatically. Each element in the array contains the data for its corresponding field in string format. The field names are loaded into another automatically-created array. The XMLNEXT() function works in a similar way to deal with all the subsequent records in the XML file. The XMLCOUNT() function can be used, as in the example below, to determine how many data records the XML file has.
The Recital/4GL includes a vast range of functions for manipulation and conversion of arrays and their individual elements. In the example program below, the XMLFIRST() and XMLNEXT() functions are used to sequentially extract each record from an XML file, whose name is passed to the program as a parameter. Once loaded into an array, the data is converted to the correct Recital data type then appended into a table. The table name is also passed as a parameter.
procedure replaceit
append blank
for i = 1 to numfields
if type(field(i)) = "N"
replace &(field(i)) with val(data[&i])
elseif type(field(i)) = "D"

Alternative Import/Export Methods
Other features exist in Recital to facilitate the import and export of data:
RDDs
The RDDs, Replaceable Database Drivers, are available on Windows, Linux and all supported 32-bit UNIX platforms. They allow for the use and creation of database tables and indexes in FoxPro, dBase and Clipper formats. The file format is the same across all the platforms that support the RDDs, allowing the tables and indexes to be transferred as required. The formats are also supported by a wide range of third-party products as well as their originating database systems. For more information on the RDDs, please see the online documentation on Xbase migration and the SET FILETYPE command.
BUILD/INSTALL
These are Recital/4GL commands for the export (BUILD) and import (INSTALL) of Recital tables and their associated memo, dictionary and multiple index files in ASCII format to allow them to be transferred across binary incompatible platforms. For more information, please see the online documentation on Recital/4GL commands.
COPY Commands
The COPY TO, COPY STRUCTURE, COPY STRUCTURE EXTENDED and CREATE FROM commands can all be used to enable data to be transferred between different formats and different platforms. For more information, please see the online documentation on Recital/4GL commands.

Here's how to set up field validation for a field with a small static number of acceptable values.
Using the example.dbf table from the southwind sample database, validation can be added to the title field to ensure it matches one of a list values.
open database southwindThe inlist() function checks whether the specified expression exists in the comma-separated list which follows. An attempt to update title with a value not in the list will give an error: Validation on field 'TITLE' failed.
alter table example add constraint;
(title set check inlist(alltrim(title),"Miss","Mr","Mrs","Ms"))
If you have access to the Recital Workbench, you can use the modify structure worksurface to add and alter your dictionary entries, including a customized error message if required.

[data] oplocks = False level2 oplocks = False
veto oplock files = /*.dbf/*.DBF/*.ndx/*.NDX/*.dbx/*.DBX/*.dbt/*.DBT/
You can further tune samba by following this guide.
mount -t cifs {mount-point} -o username=name,pass=pass,directio
The directio option is used to not do inode data caching on files opened on this mount. This precludes mmaping files on this mount. In some cases with fast networks and little or no caching benefits on the client (e.g. when the application is doing large sequential reads bigger than page size without rereading the same data) this can provide better performance than the default behavior which caches reads (readahead) and writes (writebehind) through the local Linux client pagecache if oplock (caching token) is granted and held. Note that direct allows write operations larger than page size to be sent to the server.

This is a good primer for getting familiar with using Infiniband with Redhat/Centos Linux.
http://people.redhat.com/dledford/infiniband_get_started.html
Getting Started with InfiniBand
The first step to using a new infiniband based network is to get the right packages installed. These are the infiniband related packages we ship and what they are there for (Note, the Fedora packages have not all been built or pushed to the repos yet, so their mention here is as a "Coming soon" variety, not an already done variety):
- edit the .vmx file and add the following line
uuid.action = "keep"
- set the virtual machine to power off when vmware is stopped. Do not set this to "suspend" or it will not restart on the backup machine.
