This section explains the tasks required before installing this product.
Configure the /etc/hosts file so that network name resolution is enabled for the CEP Server host name (*1).
When registering the CEP Server host name as "127.0.0.1" (CEP Server loopback address), check the following points:
When setting the host name of the CEP Server for "127.0.0.1", always first describe the IP address setting used when gaining access from outside the CEP Server.
Alternatively, do not set the host name of the CEP Server for "127.0.0.1".
*1: The HOSTNAME parameter setting in the /etc/sysconfig/network file.
Example
Example of setting /etc/hosts
Below is an example of setting the host name "cepsv1" for "127.0.0.1". In this example, the IP address setting used when gaining access from outside the CEP Server is "10.10.10.10".
10.10.10.10 cepsv1
127.0.0.1 cepsv1 localhost.localdomain localhost

anyPort | Port number used by the input adapter known as the socket adapter to receive input events. Use this by setting one unused port number between 5001 and 32767 for each CEP engine, and by setting a maximum of five for the entire CEP Server. Setting the port numbers to be used is done in CEP engine setup after installation. Port number 9600 is set in the CEP engine created at initial setup. |
Check that the disks have sufficient free capacity. Refer to "4.2.3 Resources Required at Installation" for information on the required disk capacity.
If there is a shortage of free disk capacity, extend the size.
Create a specific user and group to execute the CEP engine. Each of the processes of the CEP engine run with the user and group permissions created here.
Example
Operation example of creating the engine execution user and group using the user name "isbdcep" and the group name "isbdcep"
$ su -<ENTER>
# /usr/sbin/groupadd isbdcep<ENTER>
# /usr/sbin/useradd -g isbdcep isbdcep<ENTER>
Note
The user creation method depends upon the management policy of the system. Always check with the system administrator.
Up to 8 characters can be specified for the user name and the group name.
Kernel parameters must be tuned in advance when operating this product.
Edit /etc/sysctl.conf to change the values of the target kernel parameters to suitable values, according to the parameter "type".
If the type is "Maximum":
If the value already set (initial value or previously set value) is greater than the value shown in the table, it need not be changed. If it is smaller than the value in the table, change it to the value in the table.
If the type is "Additional"
Add the value shown in the table to the value that is already set (initial value or previously set value). Check the system maximum values before adding this value and, if adding that value would exceed the system maximum value, set the system maximum value.
The current kernel parameters can be verified using "/sbin/sysctl -a".
After making the changes, execute "/sbin/sysctl -p /etc/sysctl.conf" or reboot the OS.
Refer to the documentation for the operating system for information on how to change the kernel parameters.
Below are the kernel parameters to be set.
Shared memory
Parameter | Description | Value to be set | Type |
|---|---|---|---|
kernel.shmmax | Maximum size in shared memory | 57413492 | Maximum |
kernel.shmmni | Maximum number of shared memory segments | 41 | Additional |
Semaphore
For semaphore settings, set the values for each parameter in the following format:
kernel.sem = SEMMSL SEMMNS SEMOPM SEMMNI
Parameter | Description | Value to be set | Type |
|---|---|---|---|
SEMMSL | Maximum number of semaphores for each semaphore identifier | 512 | Maximum |
SEMMNS | Number of semaphores for the system as a whole | 5763 | Additional |
SEMOPM | Maximum number of operators for each semaphore call | 50 | Maximum |
SEMMNI | Number of semaphore operators for the system as a whole | 1143 | Additional |
Message queue
Parameter | Description | Value to be set | Type |
|---|---|---|---|
kernel.msgmax | Maximum message size | 16384 | Maximum |
kernel.msgmnb | Maximum number of bytes of messages in the message queue | 32768 | Maximum |
kernel.msgmni | Maximum number of message queue IDs | 526 | Additional |
When operating this product, adjust the user limitations for the number of processes (threads) that can be executed.
Edit "/etc/security/limits.conf" and change the number of processes (threads) that the user can execute to an appropriate value.
For this product, set the number of processes (threads) the engine execution user can execute to "2048" or higher. Add "2048" to the already specified value (the initial or previously specified value).
The number of processes (threads) that the engine execution user can execute can be checked with the following command as a superuser.
# /bin/su -c 'ulimit -u' engineExecutionUser <ENTER>
Reboot the OS after changing the value.
Refer to the OS manual for information on how to change the value.
Example
Example for setting /etc/security/limits.conf
This is an example for specifying the number of processes (threads) an engine execution user can execute. In this example, the value is set by adding "2048" to the default value of "1024".
