Sun Microsystems 2005Q2 quick start To Configure Your System for Hadb

▼To Configure Your System for HADB

Steps 1. Get root access.

2.Define variables related to shared memory and semaphores.

■On Solaris:

a.Add these lines to the /etc/system file (or if these lines are in the file as comments, uncomment them and make sure that the values match these):

set shmsys:shminfo_shmmax=0x80000000 set shmsys:shminfo_shmseg=36

set semsys:seminfo_semmnu=600

Set shminfo_shmmax to the total memory in your system (in hexadecimal notation the value 0x80000000 shown is for 2 Gigabytes of memory).

If the seminfo_* variables are already defined, increment them by the amounts shown. The default values for seminfo_semmni and seminfo_semmns do not need to be changed. The variable shminfo_shmeg is obsolete after Solaris 8.

b.Reboot, using this command: sync; sync; reboot

■On Linux:

a.Add these lines to the /etc/sysctl.conf file (or if they are in the file as comments, uncomment them). Set the value to the amount physical memory on the machine. Specify the value as a decimal number of bytes. For example, for a machine having 2 GB of physical memory:

echo 2147483648 > /proc/sys/shmmax echo 2147483648 > /proc/sys/shmall

b.Reboot, using this command: sync; sync; reboot

■On Windows: No special system settings are needed.

3.If you used existing JDK software when you installed a standalone Application Server, check the JDK version.

HADB requires Sun JDK 1.4.1_03 or higher (for the latest information on JDK versions, see the Sun Java System Application Server Enterprise Edition 8.1 2005Q2 Release Notes). Check the version installed, and if it is not done already, set the JAVA_HOME environment variable to the directory where the JDK is installed.

4.If necessary after the reboot, restart the domain, Web Server, and node agent. To restart the domain, use the command asadmin start-domain domain1.
