• make
• X Display Server

Other Requirements

The following are other requirements for Linux x86-64 (64-bit).

Patching Oracle E-Business Suite

Kernel Settings

Edit the /etc/sysctl.conf file to configure your kernel settings. After editing the file, use the "sysctl -p" command or restart the system to invoke the new settings.

OL5.4中，直接在 /etc/sysctl.conf 后增加

kernel.msgmnb = 65535
kernel.msgmax = 8192
kernel.shmmax = 68719476736
kernel.shmall = 2097152
kernel.sem = 256 32000 100 142
kernel.shmni = 4096
kernel.msgmni = 2878
net.core.rmem_default = 262144
net.core.wmem_default = 262144
fs.file-max = 6815744
net.core.rmem_max = 4194304
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500

Domain Name System (DNS) Resolver Parameters

在 /etc/resolv.conf 增加

options attempts:5
options timeout:15

在 /etc/security/limits.conf 下增加

* hard nofile 65535

* soft nofile 4096

* hard nproc 16384

* soft nproc 2047

更改/etc/hosts

127.0.0.1 localhost.localdomain localhost

HOSTNAME=[node_name].[domain_name]

If you changed any files in the previous steps, restart the system.

打补丁6078836 ，将补丁中的  libdb.so.2  复制到 /usr/lib下即可。

该步骤不做，则httpserver无法启动

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 Document 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 .

OPMN port conflict

To address this issue, perform. the following steps before installing or upgrading:

• Check if the port 6000 is being used ("netstat -a | grep 6000")
• If so, you should disable the graphics console login process on the Linux server. This can be accomplished by logging in as root and issuing the following commands:
  • Find the process that uses port 6000 by the command "lsof -i TCP:6000".
  • Use "kill -9" to abort the process found in the previous step
  • Confirm that nothing is listening at port 6000 ("netstat -a | grep 6000")
  • Modify /etc/inittab by changing "id:5:initdefault:" to "id:3:initdefault:"
  • Run "/sbin/init 3" to restart dtlogin

 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.

Manually fix database dbf file for Fresh production (PROD) database installs

For all versions of the startCD, including the current version 12.1.1.11 (see Oracle Applications Release Notes, Release 12.1.1 My Oracle Support Document 798258.1), you must run the following sql commands to fix a particular corrupted dbf file if installing the production (PROD) database:

$ sqlplus/nolog
sql> connect / as sysdba

sql> alter database datafile '[full path of system09.dbf]' resize 1000M;
sql> alter database datafile '[full path of system09.dbf]' resize 1500M;

Relink Advanced Supply Chain Planning executables (for SLES 10 and Oracle Linux/RHEL 5.4 or higher only)

During the relink phase of the installation of EBS Release 12 (12.1.1) on SLES 10 or Oracle Linux/RHEL 5.4 (Update 4 or higher), failures will result while relinking the Advanced Supply Chain Planning (ASCP) executables MSO, MSC, MSR and FEM. 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):

On each application tier server node:

LD_LIBRARY_PATH is set in three places:

• $APPL_TOP/admin/adovars.env
• $ORA_CONFIG_HOME/10.1.2/[CONTEXT_NAME].env, in the 10.1.2 Oracle home directory
• $ORA_CONFIG_HOME/10.1.3/[CONTEXT_NAME].env, in the 10.1.3 Oracle home directory

In the AutoConfig interface, this corresponds to:

Location	Parameter
adovars	LD_LIBRARY_PATH
tools_home (10.1.2)	LD_LIBRARY_PATH
web_home (10.1.3)	LD_LIBRARY_PATH

On the database server node:

LD_LIBRARY_PATH is set in $ORACLE_HOME/[CONTEXT_NAME].env which corresponds in the AutoConfig interface to:

Location	Parameter
db_home	LD_LIBRARY_PATH

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 Issues

The following are known issues for this release.

Advanced Supply Chain Planning product (MSO) may crash when increasing number of threads for optimization

The 64-bit Oracle Advanced Supply Chain Planning executable MSONWL64.exe may crash when increasing the number of threads for optimization on a system with insufficient memory (bug 7259631). The following error is observed when this occurs:

**** glibc detected *** MSONWL64.exe: corrupted double-linked list: 

    0x00002aaaac0008b0 ****
