Please refer to the following My Oracle Support Knowledge documents for more information:
SOFTWARE REQUIREMENTS
The following maintenance tools must be installed on all machines, and their locations specified both in the PATH of the account that runs Rapid Install and in the PATH of the accounts that will own the database tier and application tier file systems.
OTHER REQUIREMENTS
The following are other requirements for Linux x86 (32-bit).
Kernel Settings
Edit the /etc/sysctl.conf file to configure your kernel settings to the minimum values shown below. After editing the file, use the "sysctl -p" command or restart the system to invoke the new settings.
The following table lists the kernel settings for Oracle Linux 4, 5 and 6, Red Hat Enterprise Linux 4, 5 and 6 and SUSE Linux Enterprise Server 10:
2: On the server running the EBS Database, this kernel parameter must be the lesser of half the size of the physical memory (in bytes) and 4294967295 3: values recommended for the local port range may need to be adjusted according to the specific needs of the user's environment in order to avoid port conflicts. 4: The listed value is the minimum requirement - we recommend an actual setting that is at least equal to the sum of all the SGAs on the system divided by the page size. Domain Name System (DNS) Resolver Parameters
Two Domain Name System (DNS) resolver parameters (timeout and attempts) are set by default to low values when the operating system is installed. These low values may cause attempted network connections to an Oracle database to fail. If this happens, add or update the following entries to these minimum settings in the /etc/resolv.conf file on each server node:
options attempts:5 options timeout:15 Verifying Host Names
Use the following to verify host name settings:
For Oracle Linux 5 and 6, and Red Hat Enterprise Linux 5 and 6:
Modifying the Number of Open File Descriptors
Open the /etc/security/limits.conf file and change the existing values for "hard" and "soft" parameters as follows. Restart the system after making changes.
* hard nofile 65535 * soft nofile 4096 * hard nproc 16384 * soft nproc 2047 OS Library Patch for Oracle HTTP Server (on Oracle Linux 5, RHEL 5, Oracle Linux 6 and RHEL 6 only)
Download and apply the patch 6078836 from My Oracle Support to fix an issue with the Oracle HTTP Server (missing libdb.so.2) bundled with the E-Business Suite technology stack.
Note that this patch (which includes a required operating system library) must be applied before installing Oracle E-Business Suite. Link to Motif library for Oracle Application Server 10.1.2 (on Oracle Linux 5, RHEL 5, Oracle Linux 6 and RHEL 6 only)
Perform the following command (as root on your system) to update a required link to a Motif library prior to relinking or patching the 10.1.2 Application Server Oracle Home:
# unlink /usr/lib/libXtst.so.6 # ln -s /usr/X11R6/lib/libXtst.so.6.1 /usr/lib/libXtst.so.6
Without this updated link, you may see the following errors during a relink of the 10.1.2 Oracle Home:
/usr/lib/libXtst.so.6: undefined reference to `__stack_chk_fail@GLIBC_2.4' /usr/lib/libXtst.so.6: undefined reference to `__fprintf_chk@GLIBC_2.3.4' /usr/lib/libXtst.so.6: undefined reference to `__sprintf_chk@GLIBC_2.3.4'
Since the ldconfig command overrides this link, the above link command (ln) will have to be re-issued after running the ldconfig command.
BEFORE INSTALLING OR UPGRADING
If the Release 12.1.1 installation or upgrade is performed with the Rapid Install wizard (either a new R12 installation or upgrade from 11i to R12), ensure you have the latest Rapid Install patch as described in Oracle Applications Release Notes, Release 12.1.1 (My Oracle Support Doc 798258.1) before you begin your installation or upgrade.
Complete all operating system requirements, software requirements, and other requirements before installing or upgrading Oracle E-Business Suite.
Upgrade Oracle Database and Oracle Application Server (Oracle Linux 6 and RHEL 6 only)
Customers who are cloning to Oracle Linux 6 or RHEL 6 must first upgrade the Oracle Database to 11gR2 (11.2.0.3 or higher) and Oracle Application Server 10gR3 to 10.1.3.5 on the source 12.1.1 system using the respective documents:
Customers who are installing the E-Business Suite on these OS'es using Rapid Install must upgrade these technology components after the installation of EBS 12.1.
OPMN port conflict
To address this issue, perform the following steps before installing or upgrading:
INSTALLING OR UPGRADING
Perform the installation or upgrade following the documentation (Oracle E-Business Suite Installation Guide: Using Rapid Install, Oracle E-Business Suite Upgrade Guide: Release 11i to Release 12.1.1 or Oracle E-Business Suite Release 12.1.1 Maintenance Pack instructions) relevant to the specific installation or upgrade scenario described above.
AFTER INSTALLING OR UPGRADING
Perform the following steps after installing or upgrading to Release 12.1.1 and before allowing users to access the system.
Patch AS 10g (10.1.2 and 10.1.3) Oracle Homes (Oracle Linux 6 and RHEL 6 only)
After installation, users must update the stub libraries in the 10.1.2 and 10.1.3 Oracle Homes by installing the patch 12415211.
Users must specifically copy the files in the patch to the specified directories as follows for the 10.1.2 Oracle Home:
$ cd <12.1_INSTALL_DIR>/apps/tech_st/10.1.2/lib $ cp -p -R stubs stubsORIG $ cd stubs $ cp <PATCH_INSTALL_DIR>/12415211/files/lib/stubs/libgcc_s-2.3.2-stub.so . $ ln -s libgcc_s-2.3.2-stub.so libgcc_s.so.1 $ ln -s libgcc_s.so.1 libgcc_s.so
After this is done and sourcing the APPS<CONTEXT_NAME>.env file, users should relink all 10.1.2 executables by running the $ORACLE_HOME/appsutil/clone/adlnktools.sh script and ensuring that there are now no errors in the make log file output from the script.
The instructions for the 10.1.3 Oracle Home are:
$ cd <12.1_INSTALL_DIR>/apps/tech_st/10.1.3/lib $ cp -p -R stubs stubsORIG $ cd stubs $ cp <PATCH_INSTALL_DIR>/12415211/files/lib/stubs/libgcc_s-2.3.2-stub.so . $ ln -s libgcc_s-2.3.2-stub.so libgcc_s.so.1 $ ln -s libgcc_s.so.1 libgcc_s.so
After this, users should relink sqlplus by running the <INSTALL_DIR>/apps/tech_st/10.1.3/appsutil/clone/adlnkweboh.sh script and ensuring that there are now no errors in the make log file output from the script.
Create softlink to required library for AS 10.1.3 (Oracle Linux 6 and RHEL 6 only)
After installation, users may notice that the Apache httpd process does not start up and fails with the error:
error while loading shared libraries: libdb-4.3.so: cannot open shared object file: No such file or directory
Users (with root permissions) should create a softlink for the library using the commands:
# cd /usr/lib # ln -s libdb-4.7.so libdb-4.3.so Upgrade Oracle Database and Oracle Application Server (Oracle Linux 6 and RHEL 6 only)
Customers installing E-Business Suite 12.1.1 on Oracle Linux 6 using Rapid Install must upgrade the Oracle Database to 11gR2 (11.2.0.3 or higher) and Oracle Application Server 10gR3 to 10.1.3.5 after installing EBS 12.1 using the respective documents:
Customers who are cloning an existing EBS environment to a new Oracle Linux 6 system must ensure that their original E-Business Suite instance has been upgraded to 11gR2 and 10.1.3.5 prior to performing the clone.
Relink Advanced Supply Chain Planning executables (for Oracle Linux/RHEL 5.4 or higher only)
During the relink phase of the installation of EBS Release 12 (12.1.1) on Oracle Linux/RHEL 5.4 (Update 4 or higher), failures will result while relinking the Advanced Supply Chain Planning (ASCP) executables. To fix this problem, users are required to replace the following line under the Linux section of the $AD_TOP/bin/adrelinknew.sh:
CPP_LDFLAGS=' -L$(ORACLE_HOME)/lib -L$(ORACLE_HOME)/lib/stubs -lclntsh'
with
CPP_LDFLAGS=' -L$(ORACLE_HOME)/lib -L$(ORACLE_HOME)/lib/stubs -lclntsh -Wl,--noinhibit-exec'
After making this change, users are then required to run the adadmin utility and relink application executables.
LD_LIBRARY_PATH Environment Variable
Dynamic libraries are used as part of the relinking and execution processes. The LD_LIBRARY_PATH environment variable is used by Oracle E-Business Suite to locate the required dynamic libraries at runtime - this variable is set by the Rapid Install wizard during the installation of EBS as well as by the Rapid Clone script (adcfgclone) when configuring the target system.
If you need to change these values, use the Edit Parameters function of the OAM AutoConfig tool (by logging in as 'System Administrator' responsibility, clicking on 'System Administrator', selecting 'AutoConfig' under 'Oracle Applications Manager', and clicking on the 'Environments' tab):
After making these changes, run AutoConfig (adautocfg.sh) to implement the changes on the application and database tiers.
Net Service Listeners in Multi-user Installations
Net Service Listeners use the /var/tmp.oracle directory to store temporary files. To give all users in a multi-user installation write privileges, update /var/tmp/.oracle with 777 permissions:
$ chmod 777 /var/tmp/.oracle Known IssuesThe following are known issues for this release.Patching Application Server Oracle Homes using OPatch (Oracle Linux 6 and RHEL 6 only)
After an installation or clone of Release 12 on an Oracle Linux 6 machine, you will need to set the OPATCH_PLATFORM_ID to '46' prior to applying patches to the 10.1.2 or 10.1.3 Application Server Oracle Homes. For example, in the "ksh" shell:
This step is needed to avoid an OPatch Config Assistant failure.
