Many motherboards nowadays have integrated gigabit ethernet that use the Realtek NIC chipset.

The Realtek r8168B network card does not work out of the box in Redhat/Centos 5.3: instead of loading the r8168 driver, modprobe loads the r8169 driver, which is broken as can be seen with ifconfig which shows large amounts of dropped packets. A solution is to download the r8168 driver from the Realtek website and install it using the following steps:

Check whether the built-in driver, r8169.ko (or r8169.o for kernel 2.4.x), is installed.

# lsmod | grep r8169

If it is installed remove it.

# rmmod r8169

Download the R8168B linux driver from here into /root.

Unpack the tarball :

# cd /root
# tar vjxf r8168-8.012.00.tar.bz2

Change to the directory:

# cd r8168-8.012.00

If you are running the target kernel, then you should be able to do :

# make clean modules   
# make install
# depmod -a
# insmod ./src/r8168.ko (or r8168.o in linux kernel 2.4.x)

make sure modprobe knows not to use r8169, and that depmod doesn’t find the r8169 module.

# echo "blacklist r8169" >> /etc/modprobe.d/blacklist
# mv /lib/modules/`uname -r`/kernel/drivers/net/r8169.ko   \
        /lib/modules/`uname -r`/kernel/drivers/net/r8169.ko.bak

You can check whether the driver is loaded by using the following commands.

# lsmod | grep r8168
# ifconfig -a

If there is a device name, ethX, shown on the monitor, the linux driver is loaded. Then, you can use the following command to activate it.

# ifconfig ethX up

After this you should not see any more dropped packets reported.

Recital on Linux 64 bit requires certain 32 bit libraries for installation and/or operation.  It also needs to be installed and configured as the root user, or using sudo for those systems without a root login.

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.

Centos 6:

sudo yum install zlib-devel.i686 pam-devel.i686

(and accept dependencies)
Then run the installer in text mode

sudo ./recital-10.0.3-linux32.bin --mode text

Run Recital with sudo the first time, to set the system filetype compatiblity settings.

sudo recital

After saving the compatibility settings, quit to exit, then run Recital as your preferred user.

> quit
$ recital

RedHat / Fedora family:

sudo yum install zlib-devel.i686 pam.i686

(and accept dependencies)
Then run the installer in text mode

sudo ./recital-10.0.3-linux32.bin --mode text

Run Recital with sudo the first time, to set the system filetype compatiblity settings.

sudo recital

After saving the compatibility settings, quit to exit, then run Recital as your preferred user.

> quit
$ recital

 Ubuntu family:

sudo apt-get install ia32-libs 

In later versions of Ubuntu, ia32-libs is obsolete. The following package should be installed:

sudo apt-get install lib32z1

Ubuntu 12.04 and above also require the following:

sudo apt-get install libpam0g:i386

Then run the installer in text mode

sudo ./recital-10.0.3-linux32.bin --mode text

Run Recital with sudo the first time, to set the system filetype compatiblity settings.

sudo recital

After saving the compatibility settings, quit to exit, then run Recital as your preferred user.

> quit
$ recital

Recital 10 enhances the APPEND FROM command. The enhancement was added to the following syntax ;

APPEND FROM  <table-name> 

Before when appending into a shared Recital table each new row was locked along with the table header, then unlocked after it was inserted. This operation has now been enhanced to lock the table once, complete inserting all the rows from the table and then unlock the table. The performance of this operation has been increased by using this method. All the database and table constraints are still enforced.
