Remote Desktop Disconnected

2009-10-20T05:30:00.000-07:00

Error: The remote session was disconnected because there are no Terminal Server Client access licence available for this computer. Please contact the server administrator.

Solutions: Create a backup of the MSLicensing registry key and its subkeys on the client, and then remove the original key and subkeys by doing the following:

On the client, navigate to the following registry subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSLicensing.
Click MSLicensing.
On the Registry menu, click Export Registry File.
In the File name box, type mslicensingbackup, and then click Save.
If you need to restore this registry key in the future, double-click mslicensingbackup.reg.
On the Edit menu, click Delete, and then click Yes to confirm the deletion of the MSLicensing registry subkey.
Close Registry Editor, and then restart the computer.
When the client is restarted, the missing registry key is rebuilt.

Caution: You must be very carefull while editing registry. Always take backup of registry before editing restry.

Oracle10g installation on CentOS 4.8

2009-10-11T22:11:00.000-07:00

1 Introduction

Installing Oracle 10g on Centos 4.8 contains many steps which are including editing and configuring Centos Linux system files. So be sure that the person performing the following steps must have the basic Linux administration knowledge.

2 Installing CentOS 4.8

Boot from CentOS 4.8 DVD

Select the ‘Skip’ option and press ‘Enter’.

The welcome screen of CentOS installation appears click on ‘Next’
Select the default language option. I.e. English Click on ‘Next’. Select the default Keyboard layout. I.e. U.S English. Click ‘Next’. We need to select the ‘Server’ option and Click on ‘Next’. Select the option ‘Automatically partition’. Click on ‘Next’. Click on ‘Yes’ Tab. Select the option ‘Remove all partitions on this system’. Click on ‘Next’. Click on ‘Yes’ Tab. Installer shows the overview of new partition. Click on ‘Next’.
Now the boot loader GRUB will be installed. You can leave the default settings unchanged and click on ‘Next’. Click on the Edit button at the top right.
In the window that pops up uncheck Configure using DHCP and give your network card a static IP address
Set the hostname manually, e.g. server name.example.com, and enter a gateway (e.g. 192.168.1.XX)
Select the option ‘No firewall’ and Disable SELinux. Click on ‘Proceed’ Tab. Select the default option. Click ‘Next’ to proceed.
Here we have to select the time zone which is appropriate for you. Enter the ‘Root’ password. Package Group Selection

Select only the package sets shown here and leave all others unselected.

Desktop

X Window System
Gnome

Applications

Graphical Internet (optional)

Servers

Do not select anything in this group.

Development

Development Tools

System

Administration Tools
System Tools

Add the package 'sysstat' by clicking on the Details link and selecting "sysstat - The sar an iostat system monitoring commands." from the Optional Packages list.

Miscellaneous

Do not select anything in this group.

Click on Next to proceed.

Click ‘Next’ to proceed.

Click on ‘Reboot’ Tab. The system will restart.

After restarting the machine, logon to server using ‘root’ user name and password. Check whether all the required rpm packages for Oracle 10g installation are installed in the system. For that issue the following commands in the terminal.

rpm -q binutils compat-db control-center gcc gcc-c++ glibc glibc-common \

gnome-libs libstdc++ libstdc++-devel make pdksh sysstat xscreensaver libaio openmotif21

Some required rpms won’t be installed during the CentOS 4.8 Linux installation. To install those rpms insert the CentOS 4.8 DVD in the DVD drive.

Open Terminal window

Type ‘cd /media/cdrom/CentOS/RPMS

Type rpm –ivh “rpm name”

After installing the rpms issue the rpm check command again

3 Configuring Linux for Oracle

3.1 Verifying system requirements

To verify that your system meets the minimum requirements for an Oracle Database 10g Release 2 database, log in as root and run the commands below

To check the amount of RAM and swap space available, run this:

grep MemTotal /proc/meminfo

grep SwapTotal /proc/meminfo

Ex:

# grep MemTotal /proc/meminfo

MemTotal: 1034680 kB

# grep SwapTotal /proc/meminfo

SwapTotal: 1534196 kB

The minimum RAM required is 1024MB, and the minimum required swap space is 1GB. Swap space should be twice the amount of RAM for systems with 2GB of RAM or less and between one and two times the amount of RAM for systems with more than 2GB

You also need 2.5GB of available disk space for the Oracle Database 10g Release 2 software and another 1.2GB for the database. The /tmp directory needs at least 400MB of free space. To check the available disk space on your system, run the following command:

df -h

Ex:

# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/sda3 6.8G 1.3G 5.2G 20% /

/dev/sda1 99M 17M 77M 18% /boot

3.2 Create the Oracle Groups and User Account

Ex:

# /usr/sbin/groupadd oinstall

# /usr/sbin/groupadd dba

# /usr/sbin/useradd -m -g oinstall -G dba oracle

# id oracle

uid=501(oracle) gid=502(oinstall) groups=502(oinstall),503(dba)

Set the password on the oracle account:

passwd oracle

Ex:

# passwd oracle

Changing password for user oracle.

New password:

Retype new password:

passwd: all authentication tokens updated successfully.

3.3 Create Directories

Issue the following commands as root:

Ex:

# mkdir -p /u01/app/oracle

# chown -R oracle:oinstall /u01/app/oracle

# chmod -R 775 /u01/app/oracle

3.4 Configuring the Linux Kernel Parameters

# cat >> /etc/sysctl.conf <

kernel.shmall = 2097152

kernel.shmmax = 536870912

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 65536

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default=262144

net.core.wmem_default=262144

net.core.rmem_max=262144

net.core.wmem_max=262144

EOF

# /sbin/sysctl –p

3.5 Setting Shell Limits for the oracle User

# cat >> /etc/profile <

if [ \$USER = "oracle" ]; then

if [ \$SHELL = "/bin/ksh" ]; then

ulimit -p 16384

ulimit -n 65536

else

ulimit -u 16384 -n 65536

umask 022

EOF

# cat >> /etc/csh.login <

if ( \$USER == "oracle" ) then

limit maxproc 16384

limit descriptors 65536

umask 022

endif

EOF

#cat >> /home/oracle/.bash_profile <

umask 022

PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin

LD_LIBRARY_PATH=/usr/lib:/usr/X11R6/lib

ORACLE_BASE=/u01/app/oracle

ORACLE_HOME=$ORACLE_BASE/product/10.1.0/db_1

ORACLE_SID=orcl

PATH=$ORACLE_HOME/bin:$PATH

export PATH LD_LIBRARY_PATH

export ORACLE_BASE ORACLE_HOME ORACLE_SID
