2 Package, Kernel Parameter, and Library Requirements for Enterprise Manager Cloud Control
This chapter describes the packages, kernel parameters settings, and libraries required on different platforms (32-bit and 64-bit) for installing a new Enterprise Manager system, an additional Oracle Management Service (OMS), and a standalone Oracle Management Agent (Management Agent).
In particular, this chapter covers the following:
Package Requirements for Enterprise Manager Cloud Control
This section lists the packages required on different platforms (32-bit and 64-bit) for installing an OMS or a Management Agent. In particular, this section covers the following:
About the Logic Used by the Enterprise Manager Cloud Control Installation Wizard to Verify the Packages
The Enterprise Manager Cloud Control Installation Wizard runs prerequisite checks to verify these packages. If the packages are not found or if the packages are found to be of a lower version than what is required at a minimum, then the wizard prompts you to install the required packages of the required version before proceeding with the installation or upgrade.
The package name contains two parts, mainly the name and the version separated by a hyphen. For example, for libstdc++43-4.3 package, libstdc++43 is the name and 4.3 is the version of the package.
The Enterprise Manager Cloud Control Installation Wizard verifies the package name as well as the version required for a particular platform. For example, if libstdc++43-4.3 is required for SUSE Linux Enterprise 11, and if libstdc++46-4.6.1 is found instead, then the wizard will report this as a missing package and prompt you to install libstdc++43-4.3. This is because libstdc++46-4.6.1 is not a higher version of libstdc++43-4.3; libstdc++46 and libstdc++43 are two different packages (the former is 46 and the latter is 43).
You can have a package of a higher version than what is required, but not a different package and not a package of a lower version. For example, if libstdc++43-4.3 is required for SUSE Linux Enterprise 11, and if libstdc++43-6.7 is found instead, then the wizard will not report this as an issue, and will pass the prerequisite check. This is because, in this case, libstdc++43-6.7 is a higher version of libstdc++43-4.3, which is required at a minimum (the former is 43 and so is the latter).
Therefore, as a prerequisite, make sure you install all the required packages listed in this chapter for your respective platform.
Identifying the Installed Packages
To identify the packages already installed on your system, run the following command. If the command does not list the packages listed in Package Requirements for Oracle Management Service or Package Requirements for Oracle Management Agent, then install them manually.
For Linux Platforms
rpm -qa --queryformat "%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH})\n" | grep glibc
The command lists all the packages installed on the system. The 32-bit ones are appended with (i386) or (i686), and the 64-bit ones are appended with (x86_64).
For example, if you run the command on a 32-bit system, you should see something similar to the following:
glibc-devel-2.3.4-2.43(i386)
glibc-headers-2.3.4-2.43(i386)
glibc-2.3.4-2.43(i686)
compat-glibc-headers-2.3.2-95.30(i386)
glibc-profile-2.3.4-2.43(i386)
glibc-utils-2.3.4-2.43(i386)
glibc-kernheaders-2.4-9.1.103.EL(i386)
glibc-common-2.3.4-2.43(i386)
compat-glibc-2.3.2-95.30(i386)
For example, if you run the command on a 64-bit system, you should see something similar to the following:
glibc-common-2.3.4-2.43(x86_64)
glibc-devel-2.3.4-2.43(x86_64)
glibc-profile-2.3.4-2.43(x86_64)
glibc-headers-2.3.4-2.43(x86_64)
glibc-utils-2.3.4-2.43(x86_64)
glibc-2.3.4-2.43(x86_64)For Solaris Platforms
pkginfo <package_name>
For example,
pkginfo SUNWbtoolFor AIX Platforms
lslpp -l <package name>
For example,
lslpp -l bos.perf.proctoolsFor HP Platforms
To determine whether a bundle, product, or fileset is installed, enter the following command, where level is either bundle, product, or fileset:
# /usr/sbin/swlist -l level |more
For example,
/usr/sbin/swlist -l bundle |grep QPKPackage Requirements for Oracle Management Service

Kernel Parameter Requirements for Enterprise Manager Cloud Control
This section lists the kernel parameters required on different platforms (32-bit and 64-bit) for installing an OMS or a Management Agent. In particular, this section covers the following:
Kernel Parameter Requirements for Oracle Management Service
This section covers the following:
Verifying UDP and TCP Kernel Parameters
Set TCP/IP ephemeral port range parameters to provide enough ephemeral ports for the anticipated server workload. Ensure that the lower range is set to at least 11,000 or higher, to avoid Well Known ports, and to avoid ports in the Registered Ports range commonly used by Oracle and other server ports.
Set the port range high enough to avoid reserved ports for any applications you may intend to use. If the lower value of the range you have is greater than 11,000, and the range is large enough for your anticipated workload, then you can ignore OUI warnings regarding the ephemeral port range.
For example, with IPv4, use the following command to check your current range for ephemeral ports:
$ cat /proc/sys/net/ipv4/ip_local_port_range
32768 61000
In the preceding example, the lowest port (32768) and the highest port (61000) are set to the default range.
If necessary, update the UDP and TCP ephemeral port range to a range high enough for anticipated system workloads, and to ensure that the ephemeral port range starts at 11,000 and above.
For example:
# echo 11000 65000 > /proc/sys/net/ipv4/ip_local_port_range
Oracle recommends that you make these settings permanent. For example, as root, use a text editor to open /etc/sysctl.conf, and add or change to the following: net.ipv4.ip_local_port_range = 11000 65000, and then restart the network (# /etc/rc.d/init.d/network restart). For detailed information on how to automate this ephemeral port range alteration on system restarts, refer to your Linux distribution system administration documentation.
Verifying nproc Kernel Parameter
To verify the number of processes available to the user responsible of the Enterprise Manager software installation, check the value of the nproc kernel parameter.
Table 2-3 nproc Kernel Parameter
| Parameter | Value | File |
|---|---|---|
| nproc | 4098 or higher | /etc/security/limits.conf |
Oracle recommends the minimum nproc value of 4098 for the user responsible of running the Enterprise Manager software installation.
For details on how to update the nproc kernel parameter, refer to your Linux distribution system administration documentation.
Setting Up kernel.shmmax Kernel Parameter
This section covers the following:
If OMS and Management Repository Are on Different Hosts
If you are installing OMS and Management Repository (database) on different hosts, which are running on Linux operating systems (32-bit or 64-bit), then on the OMS host, set the kernel.shmmax parameter to a value 1 byte less than 4 GB or 4294967295.
Oracle recommends this value to avoid lack of memory issues for other applications and to enable a complete and successful core file generation under any and all circumstances.
-
To verify the value assigned to the
kernel.shmmaxparameter, run the following command:cat /proc/sys/kernel/shmmax -
To set the value for
kernel.shmmaxparameter, do the following:-
Log in as root.
-
Open the
/etc/sysctl.conffile. -
Set the
kernel.shmmaxparameter to4294967295.By setting the value in the
/etc/sysctl.conffile, the value persists even when you restart the system. On SUSE Linux Enterprise Server systems, run the following command to ensure that the system reads the/etc/sysctl.conffile when it restarts:# /sbin/chkconfig boot.sysctl on -
Run the following command to change the current values of the kernel parameters. Review the output and verify that the values are correct. If the values are incorrect, edit the
/etc/sysctl.conffile, then run this command again.# /sbin/sysctl -p -
Enter the command
/sbin/sysctl -ato confirm that the values are set correctly. -
After updating the values of the kernel parameters in the
/etc/sysctl.conffile, either restart the host, or run the commandsysctl -pto make the changes in the/etc/sysctl.conffile available in the active kernel memory.
-
If OMS and Management Repository Are on the Same Host
If you are installing OMS and Management Repository (database) on the same host, which is running on a Linux operating system (32-bit or 64-bit), then set the kernel.shmmax parameter to a value prescribed in the Oracle Database Installation Guide that is published for the intended database release and platform.
Library Requirements for Enterprise Manager Cloud Control
