vncserver: couldn’t find “xauth” on your PATH

Problem:

While starting a vncserver session on linux machine, if you get the following error:

bash$> vncserver :01
vncserver: couldn’t find “xauth” on your PATH

Solution:

bash$> export PATH=$PATH:/usr/X/bin:/usr/X11/bin

Enjoy.............. :)

Installing & Configuring Apache 2.2 64bit on Solaris Sparc Box

This post is divided into 3 sections: Installation, Configuration & Verification.

So let's start the process.........

Installing Apache22-64bit-

To install apache22, we need the source code & than need to build it. This will generate the binaries.
Download the source code from http://httpd.apache.org/download.cgi#apache22 to your Solaris Sparc box.
Now we need to 'export' some settings, i.e. per-requisites before we start the build process:

export LD_LIBRARY_PATH=/usr/sfw/lib/sparcv9:/usr/local/lib/sparcv9
export PATH=/usr/sfw/bin:/usr/ccs/bin:/usr/local/ccs/bin:/usr/local/bin:$PATH
# if you want it 64 bits:
export CFLAGS=”-m64″
# if you want it 32 bits:
# export CFLAGS=”-m32″
export LDFLAGS=”-L/usr/sfw/lib/sparcv9″

4. Unzip the downloaded apache22 source code.

5. Change the directory, move to the unzipped folder.

6. Now we need to configure the environment for building the source code, for this it is

required to execute the 'configure' script present in the directory.

For eg: /home/ckukreja/sr_apache22 is the directory where you have unzipped the

source code

bash$>ls -ltr configure

7. Execute the 'configure' script.

./configure --with-included-apr --enable-so --prefix=/home/ckukreja/apache22

8. Now we need to build & install the binaries. Do the following:

make
make install

9. Now go to the directory where you have install apache22

Move to bin folder and execute the 'file' command on httpd executable file.

bash$> cd /home/ckukreja/apache22/bin
bash$> file httpd

'file httpd' - It's output will show you the type of file is it. Here it should show 64bit, if not than the binaries are of 32bit. Check the steps again.

Configure Apache22 on Solaris Sparc Box:

As you have installed the apache22 on your Solaris Machine. Now it is required to configure it before we start the server.

Go to the apache22 installation directory. Move to conf folder.

bash$> cd /home/ckukreja/apache22/conf

2. Open httpd.conf file to edit it.

bash$> vi httpd.conf

Change the port from '80' to the one you want. Like we use '8880'.
By default username & group are configured as 'daemon'. Change them to the one you are logged in with.
Save the changes & close the file.

3. Now come out of the conf folder & change your directory to bin folder.

bash$>cd /home.ckukreja/apache22/bin

4. Execute the apachectl executable. It will start the httpd server process.

./apachectl -k start

Verify the installation & configuration steps:

Try to access the default resource present on apache22 server like index.html.

Syntax: http://<hostname>:<port>/index.html

Eg: http://slc0010:8880/index.html

It will display the "It Works!!!"

So guys you are done with the Installation & Configuration of Apache22-64bit on your Solaris Sparc Machine..........!!!!!!!!!!!!!! :-)

Enjoy :-)

Install & Configure Apache 2.2 (64bit) on AIX Machine

Install Apache 2.2 (64bit) on AIX Machine:

Follow the steps:

To install apache22, we need the source code & requires to build it. This will generate the binaries.
Download the source code from http://httpd.apache.org/download.cgi#apache22 to your AIX64 box.
Now we need to export setting, that is per-requisties before we start the build process:

export OBJECT_MODE=64

     4. Untar the source zip. Change the directory to unzipped folder

     5. Execute the configure script present in the folder as follows:

LDFLAGS="-maix64" LD=gcc CFLAGS="-maix64" ./configure --prefix=/scratch/anikukum/chalja --enable-so --with-included-apr

Note:

Here we are using 'gcc' as complier, you can use other like 'xlc' etc.
The flags CFLAGS & LDFLAGS are ensuring the 64 bit compilation to be done.
--with-included-apr <this ensures that the APR, APR-Util library will be included>
--prefix <here you need to provide the path where you want to install the apache22>

6. Compile & install.

make - it will compile the source code
make install - this will install the binaries & other files at the location provided in 'prefix'.

7. Now go to the directory where you have install apache22

Move to bin folder and execute the 'file' command on httpd executable file.
'file httpd' - It's output will show you the type of file is it. Here it should show 64bit, if not than you have missed some step.

Configure Apache22 on AIX:

As you have installed the apache22 on your AIX Machine. Now it is required to configure it before we run the server.

Go to the apache22 installation directory. Move to conf folder.
Open httpd.conf file to edit it.

Change the port from '80' to the one you want. Like we use '8889'.
By default username & group are configured as 'daemon'. Change them to the one you are logged in.
Save the changes & close the file.

3. Now come out of the conf folder & change your directory to bin folder.

4. Execute the apachetl exe file. It will start the httpd server process.

./apachetl -k start

Verify the installation & configuration:

Try to access the default resource present on apache22 server like index.html.

Syntax: http://<hostname>:<port>/index.html

Eg: http://slc0010:8889/index.html

So guys you are done with the Installation & Configuration of APache22-64bit on your AIX Machine.

Enjoy :-)

Installing and Configuring Oracle Identity and Access Management 11g Release 2 (11.1.2.2.0)

Installing and configuring the latest version of Oracle Identity and Access Management 11g components involves the following steps:

Note: ** If you are installing Oracle Identity Manager, you must install Oracle SOA Suite 11g Release 1 (11.1.1.7.0). Note that only Oracle Identity Manager requires Oracle SOA Suite. This step is required because Oracle Identity Manager uses process workflows in Oracle SOA Suite to manage request approvals.

Enjoy :-)

Identifying Installation Directories

The common directories names used while installing OAM/OIM include the following:

Locating Installation Log Files

The Installer writes log files to the ORACLE_INVENTORY_LOCATION/logs directory on UNIX systems and to the ORACLE_INVENTORY_LOCATION\logs directory on Windows systems.
On UNIX systems, if you do not know the location of your Oracle Inventory directory, you can find it in the ORACLE_HOME/oraInst.loc file.
On Microsoft Windows systems, the default location for the inventory directory is C:\Program Files\Oracle\Inventory\logs.

Enjoy :-)

WebLogic server Error: Could not obtain an exclusive lock for directory.

Steps to make your OAM Admin Server Start:

1.  Shutdown the Admin Server.
2.  Delete the lok file from <domain-home>/servers/<server-name>/tmp/.

      AdminServer.lok
3.  Now start the Admin Server.
4.  If the server still fails to start then we need to kill the the process which    is still running on the server

      using following commands.

ps -ef | grep 'weblogic'

kill -9 PID

4. Now start again the Admin Server.
