Save and restore state across Recital Web pages

When using Recital Web you can maintain the exact state of each cursor between pages like this.

On entry to the .rsp page.

IF type( _session["state"] ) != "U"

    m_state = _session["state"]
    RESTORE DATASESSION FROM m_state
ELSE
    // open up your tables for the first time 
ENDIF

On exit of the .rsp page.
SAVE DATASESSION TO m_state

_SESSION["state"] = m_state

Recital 10.0.3 Installation on Linux 64 bit (Updated)

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
Ubuntu 12.04 also requires 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

HOWTO: Configure SELinux for Recital Web


SE Linux is a feature of the Linux kernel that provides mandatory access control. This policy based access control system grants far greater control over the resources on a machine than standard Linux access controls such as permissions.

Many modern Linux distributions are shipping with SELinux enabled by default, Fedora 14 and Rhel 6 both install with it enabled.

When you run Recital Web on a SELinux enabled machine and navigate to the default.rsp page you will see something similar to the screen shot below.

1
If you launch the SELinux troubleshooter you will see the following problem.

SELinux is blocking the apache server from accessing the Recital server running on port 8001.

2
To manage you SELinux policy you must have the policycoreutils package group installed. The policycoreutils contains the policy core utilities that are required for basic operation of a SELinux system.

If you wish to use a GUI tool, you must install the policycoreutils-gui package.

At the command prompt execute the following:

As root

$ yum install policycoreutils

$ semanage port -a -t http_port_t -p tcp 8001

$ service recital restart

$ service httpd restart 
 

We use the semanage command here to allow the http server access to port 8001. Once you have completed the steps detailed above you can go and navigate back to the default.rsp page in your borwser, where you will find the permission denied message is now replaced by the default.rsp page.

SELinux does a great job of restricting services and daemons so rather than simply disabling it, why not work with it!

When it comes to security, every little bit helps...
