Change AdminServer Port Using WLST.SH

Posted on by Osama Mustafa in Fusion Middleware
Sometimes AdminServer not working Regarding to Wrong configuration or using Wrong Port which mean No Console will be available so is this mean delete domain and Configure it again !!!

Absolutely  Not  When you install Weblogic any Version Oracle Provide you with Command Line Utility to administrate weblogic, what you can do it using Console can be done with this tool.

change to weblogic-directory/common/bin
./wlst.sh

Now follow the below Steps to change port :

wls:/offline> readDomain (‘/u01/app/fmw/domains/IDDomains’)
wls:/offline/IDDomains> cd (‘Server’)
wls:/offline/IDDomains/Server> ls ()

Choose your Server Here

wls:/offline/IDDomains/Server> cd (‘AdminServer’)
wls:/offline/IDDomains/Server/AdminServer> ls ()

Search for Old Port ListenPort 

wls:/offline/IDDomains/Server/AdminServer> set (‘ListenPort’,New Port)
wls:/offline/IDDomains/Server/AdminServer> updateDomain ()
wls:/offline/IDDomains/Server/AdminServer> exit () 

Done you can now Test your new port
http://Server-ip:/console

Create Group using Em12c

Posted on by Osama Mustafa in Application
Sometimes you need to create Certain group for Enterprise manager to make monitor more easy , sepcially if you have lot of agent and components such as database , Host , application server … so if you want to manage them individually it will consume time and seems to be impossible.

Enterprise manager provide you with Group Features to combine components, and there’s two type :

  • Target at the same type 
  • Target contain different components such as database, Application server , Host.

Check the below screenshot :

From Setup –> Add Target –> Group

you have five tab each one of them contain different parameters, Choose the right option that works with your Work:

After Choose the name for the group you need to add Agents, from search button new popup screen will be open choose which agent type you want.

Another example on Chart tab :

After Create Group :

For More information about Enterprise Manager 12c Group Read Oracle Documentation Here

unpack.sh Error -name=Value

Posted on by Osama Mustafa in Fusion Middleware
The pack command creates a template archive (.jar) file that contains a snapshot of either an entire domain or a subset of a domain. You can use a template that contains a subset of a domain to create a Managed Server domain directory hierarchy on a remote machine.

The unpack command Creates a full domain or a subset of a domain used for a Managed Server domain directory on a remote machine. You may use unpack only with a template compatible with your current installation. The template can be any of the following:

  •  A domain template provided by BEA and packaged with your current installation
  •  A domain template created using the Domain Template Builder or WLST Offline
  •  A domain template created using the pack command
  •  A Managed Server template created using the pack command. A Managed Server template, by default, contains only the files necessary for creating a Managed Server domain directory.
You Can Check Oracle Documentation here for more information about the above commands.
When Trying to use unpack command with the below command:

./unpack.sh -domain=/u01/app/oracle/domains/IDMDomains -template=/u01/shared/IDMdomains.jar

The below error appear :

ERROR !!! ./unpack.sh -name=Value Missing

The Solution is simple :

-template attribute should come first. 

./unpack.sh  -template=/u01/shared/IDMdomains.jar -domain=/u01/app/oracle/domains/IDMDomains

Managed Server BI_Server Unable To Start After Create Node manager Service

Posted on by Osama Mustafa in Fusion Middleware
Problem Description :

After Install Weblogic and BI On Windows, And Create Admin Server as Services BI_server unable to start, Node manager Created Service Created Without Any Error.

Cause & Solution : 

After Investigation I found Class Path is too Long So what i did like the following, Edit installSVC.cmd To set Classpath  to be Short

you will find the below line in the InstallSvc.cmd all you have to do is change it to be like Line in Red Color :

@echo off

echo %CLASSPATH% > %USERDOMAIN_HOME%\cp.properties

if “%ADMIN_URL%” == “” goto runAdmin
@echo on
set CMDLINE=”%JAVA_VM% %MEM_ARGS% %JAVA_OPTIONS%
-classpath @%USERDOMAIN_HOME%\cp.properties 
-Dweblogic.Name=%SERVER_NAME% -Dweblogic.management.username=%WLS_USER%
-Dweblogic.management.server=\”%ADMIN_URL%\”
-Dweblogic.ProductionModeEnabled=%PRODUCTION_MODE%
-Djava.security.policy=\”%WL_HOME%\server\lib\weblogic.policy\” weblogic.Server”

goto finish

Adopting NON-CDB to CBD

Posted on by Osama Mustafa in Database
This article describe steps to Adopt non-container database 12c to container 12c 

[oracle@test12c Desktop]$ ps -ef | grep pmon

oracle    3230     1  0 04:04 ?        00:00:09 ora_pmon_db12c
oracle   12112     1  0 08:20 ?        00:00:07 ora_pmon_NonCDB
oracle   29621  3203  0 18:47 pts/1    00:00:00 grep pmon

Where :
db12c : Container database
NonCDB : Non Container Database
Let Start

[oracle@test12c Desktop]$ export ORACLE_SID=NonCDB

SQL> select instance_name from v$instance ;
INSTANCE_NAME
—————-
NonCDB

SQL> shutdown immediate ;
Database closed.
Database dismounted.
ORACLE instance shut down.

SQL> startup mount exclusive
ORACLE instance started.
Total System Global Area  939495424 bytes
Fixed Size    2295080 bytes
Variable Size  348130008 bytes
Database Buffers  583008256 bytes
Redo Buffers    6062080 bytes
Database mounted.

SQL> alter database open read only;

Database altered.

Run the below procedure to generate the manifest file. 

SQL> exec dbms_pdb.describe(pdb_descr_file=>’/u01/noncdb.xml’);

PL/SQL procedure successfully completed.

SQL> shutdown immediate ;
Database closed.
Database dismounted.
ORACLE instance shut down.

 I already working on the same host so no need to copy datafiles,if you are not working on same host copy datafiles to same location.

Let’s Work On Container Database .

after copy datafiles to folder, On Os Level , Create directory to use file_name_convert.

[oracle@test12c oradata]$ mkdir newnoncdb
[oracle@test12c newnoncdb]$ pwd
/u01/app/oracle/oradata/newnoncdb

[oracle@test12c Desktop]$ export ORACLE_SID=db12c
[oracle@test12c Desktop]$ sqlplus / as sysdba

 

SQL> create pluggable database non_cdb as clone
  2  using ‘/u01/noncdb.xml’
  3  file_name_convert=(‘/u01/app/oracle/oradata/NonCDB’,’/u01/app/oracle/oradata/newnoncdb’) copy;

Pluggable database created.

 Where

  1.  using ‘/u01/noncdb.xml’ : file that should be generated using dbms_pdb.describe
  2. ‘/u01/app/oracle/oradata/NonCDB’ : location for Copied Non_CDB datafile
  3. ,’/u01/app/oracle/oradata/newnoncdb’ : location for created directory.

SQL> alter pluggable database non_cdb open ;        
Pluggable database altered.

SQL> alter pluggable database non_cdb close ;
Pluggable database altered.

SQL> alter pluggable database non_cdb open ;
Pluggable database altered.

NAME       OPEN_MODE
—————————— ———-
PDB$SEED       READ ONLY
NEWDB_PLUG MOUNTED
NEW_PLUG_COPY MOUNTED
NEW_PLUG_MOVE MOUNTED
NON_CDB       READ WRITE

Now you plugged NON-CDB to Container Database successfully without any problems and it will works fine.
the below step is optional but recommanded for production to move all thing from non-cdb to cdb. ( specially for upgrade 12c later ) 

SQL> alter session set container=Non_cdb;
Session altered.

OR 

[oracle@test12c newnoncdb2]$ sqlplus sys/sys@test12c:1521/Non_cdb as sysdba  ;

SQL> @$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql
