cp <SRF UNZIP DIRECTORY>/srf/8.2/patch/23030_srf/enu/siebel_sia.srf    $SIEBEL_HOME/ses/siebsrvr/objects/enu/siebel_sia.srf

And re-start server.

Install oracle siebel 8.1.1 on Linux x86_64

After install siebel 8.1.1, if cfgenv.sh missing.

The cfgenv.sh and cfgenv.csh files can be created as follows:

From SIEBEL_ROOT/gtwysrvr/install_script/install, run the following command:

$ ./CreateCfgEnvScript /SIEBEL_ROOT/gtwysrvr

From SIEBEL_ROOT/siebsrvr/install_script/install, run the following command:

From SIEBEL_ROOT/sweapp/install_script/install, run the following command:

$ ./CreateCfgEnvScript SIEBEL_ROOT/sweapp

Before configure gateway, please run command: 

$ export RESOLV_MULTI=off

Congfigure Gateway server:

$source cfgenv.sh

./config.sh -mode enterprise

Verify install success:

Disable SSO Report Servers on iAS10g

1. Edit file rep_<server_name>_oracle_ias2.conf in directory: $ORACLE_HOME/reportsconf

Comment lines:

  <!– <security id=”rwSec”>

      <!property name=”securityUserid” value=”%PORTAL_DB_USERNAME%/%PORTAL_DB_PASSWORD%@%PORTAL_DB_TNSNAME%” confidential=”yes” encrypted=”no”/>

      <property name=”oidEntity” value=”….”/>

   </security/–>

2. Restart Application Server

Set REPORT_PATH in $ORACLE_HOME/reports/conf/rep_<server_name>_oracle_ias2.conf

 <property name=”sourceDir” value=”/app/app10g/reports/samples/demo:<PATH>”/>

Install or Clone Oracle EBS R12.1.3 on Google Compute Cloud.

1. Create instance from Google cloud with CentOS kernel.

2. Install pre-requirement packages

#yum remove unzip

#mkdir /install

#cd /install

#wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/unzip-5.52-3.el5.x86_64.rpm

#rpm -ivh unzip-5.52-3.el5.x86_64.rpm

Enable vncserver with xterm (please view in this post).

Reboot server

#reboot

3. Configure putty to connect vncserver over ssh

Default google compute cloud only open ssh port, vncserver is not encrypt data. To secure network, we will configure vncserver over ssh with putty tool.

3.1 Open putty

Enter public IP address to hostname (or IP address)

Enter port SSH (default is 22)

In Left windows, select Connection-> SSH -> X11

Check to Enable X11 forwarding

Enter localhost:0 to X display location.

In the left windows, click to Tunnels

In Add new forward port:

Enter Source port: 5901

Enter Destination: localhost:5901

Click to Session, Enter any name in Saved sessions, click to save button.

Open putty, connect to server.

Start vncviewer on your laptop or desktop, then connect to server vnc with:

localhost:1

Done.

3. Add swap for google cloud compute: Default google cloud compute instance does not enable swap. We will enable swap on.

$sudo dd if=/dev/zero of=/swapfile bs=1024 count=1024k

$sudo mkswap /swapfile

$sudo swapon /swapfile

$swapon -s

$sudo vi /etc/fstab

/swapfile               swap                    swap    defaults        0 0

Filename Type Size Used Priority
/swapfile file 1048572 0 -1

3. Edit hosts file, add more lines with same IP.

$sudo vi /etc/hosts

127.0.0.1 localhost
169.254.169.254 metadata.google.internal metadata
10.240.XXX.XX hostname.yourdomain #Line add
10.240.XXX.XX hostname default created by GG # Added by Google

4. Install Oracle database 11gR2 (11.2.0.3) or Clone database EBS R12 follow oracle guide.

New JVM JIT Feature in 11g May Cause ORA-29516 Error on Linux

Error:

ORA-29516: Aurora assertion failure: Assertion failure at joez.c:3311
Bulk load of method java/lang/Object.<init> failed; insufficient shm-object space

Cause:

You have set additional mount options on the shared memory device, /dev/shm, other than just the option named defaults.

Solution:

Examine the mount options in file /etc/fstab. If you see any addiitonal mount options after the word “defaults” for /dev/shm, such as nosuid, nodev, or noexec then this is likely the root cause.

For example:

none /dev/shm tmpfs defaults,nosuid,nodev,noexec 0 0

Remove these options from the entry in /etc/fstab:

none /dev/shm tmpfs defaults 0 0

Shut down the database instance, and reboot the system.  Restart the database instance.

Or

Disable the JIT compiler:

Alter system set JAVA_JIT_ENABLED=FALSE scope=both;

Steps to fix this errors:

1. Go to %Oracle_home%\appsutil\bin

2. Run command: adgenhnm.exe %oracle_home% or path which point to %oracle_home%

3. Check errors occur and fix it.

Example:  PATH not found in SOFTWARE ORACLE ID18

4. Open regedit: Start -> Run -> regedit

5. Find HKEY_LOCAL_MACHINE -> SOFTWARE -> ORACLE -> ALL_HOMES -> ID18

6. Add New Strings value in right windows with PATH and value point to %oracle_home% (EX: D:\dev8\dev8db\9.2.0)

7. Re run adcfgclone.pl dbTier with command

     D:\dev8\dev8db\9.2.0\appsutil\clone\bin\perl adcfgclone.pl dbTier
