How to Deploy SSL Certificates on Oracle Weblogic

We can use below query to check all concurrent managers status with node name and number of actual/target processes.

Script:


SELECT   b.user_concurrent_queue_name "Concurrent Manager", a.TARGET_NODE "Node", a.running_processes "ACTUAL Processes", a.max_processes "TARGET Processes"
   ,DECODE (b.control_code
     ,'D', 'Deactivating'
     ,'E', 'Deactivated'
     ,'N', 'Node unavai'
     ,'A', 'Activating'
     ,'X', 'Terminated'
     ,'T', 'Terminating'
     ,'V', 'Verifying'
     ,'O', 'Suspending'
     ,'P', 'Suspended'
     ,'Q', 'Resuming'
     ,'R', 'Restarting'
     ) status
  FROM apps.fnd_concurrent_queues a, apps.fnd_concurrent_queues_vl b
    WHERE a.concurrent_queue_id = b.concurrent_queue_id AND a.running_processes = a.max_processes
 ORDER BY a.max_processes DESC;

In this post I am going to cover the concepts of Oracle Data Gaurd.

Oracle Datagaurd is part of Oracle Maximum Availability Architecture(MAA) which includes various Oracle technologies like RAC,ASM,Flashback, Active DataGaurd and Goldengate.

Datagaurd is part of MAA and used for Data protection which provides a disaster recovery solution for Oracle Databases. It also be considered as a High Availability Solution*.
For Datagaurd we can  keep the DR on different servers,data centers or geographical location to provide best data protection.



























In the DR environment the source database from where data is synced to target database is called as PRIMARY Database and the target database is know as Standby Database. The above picture represents simple architecture for a basic DR configuration.

DR sends the redo log files to standby database so it is also know as log  shipping based replication.
DR is a unidirectional replication which means that any changes to data made in Primary would only move to standby. No changes can be done at standby side

Hello and welcome to the Oracle DataGaurd Tutorial Series of post. In these post I would be sharing the guide to start understanding and working on data gaurd.

You should be having some prior knowledge on 

a) Oracle Database administration Basics
b) Basic of Linux Command
c) Have knowledge of working on virtual box and setting up server.

I will be covering topics related to below in this series.

1) Introduction to Oracle DataGaurd- Understanding the concepts.
2) Create and Manage Physical and Logical Standby database.
3) Understanding and Configuring Data Gaurd Broker and using it to monitor Data Gaurd.
4) How to do role transition (Switch Over and Failover)
5) How to setup Fast-Start Failover(FSFO)
6) How to setup Active Data Gaurd
7) How to setup Snapshot Standy Database
8) Implement Client Failover
9) How to Use RMAN for datagaurd environments

I would be using Oracle Virtual Box to setup the Oracle Data Gaurd Environment.

Environment Requirement
1. Virtual Box software latest version
2. Database software 12cR1(12.1.0.2)
3. Oracle Enterprise Linux 6.4 64 bit
4  Putty or ssh terminal(In case of Linux)
5. Using the above , I have setup two Machines on virtual box.(How to create Virtual Machine and Install Oracle database). I would not separately mention, how to install oracle database as part of this series. I would assume you would have already completed that. In case of any issue, Please mention in comment section.

In this post I am going to share how to install Oracle EBS R12.2 on multiple nodes. Which means Database on one server and Application on one server.

I am using Oracle Virtual Box and configured 2 servers, one for Database and one for Application.

Virtual Server/Machine Details

Database Node
Memory: 6 GB
Harddisk: 200 GB
Hostname: fundb.lab
IP: 192.168.56.80
OSuser: oracle
Stage Area has been created separately on nodes and is non shared

Application Node

Memory: 7 GB
Harddisk: 270 GB
Hostname: funapp.lab
IP: 192.168.56.81
OSuser: applmgr
Stage Area has been created separately on nodes and is non shared

 Please perform all the pre-reqs on both nodes as described in earlier post.
1) user creation
2) rpm installation and limits configuration
3) oraInst.loc

Refer https://www.funoracleapps.com/2017/02/installing-oracle-apps-r122-step-by.html for steps by step pre-installation method setup.

Also make sure hostname are pingable from each other. This can be achieved by putting the entries in /etc/hosts file.

Once both the servers are ready to installation. Please follow below steps

1) Kick-off rapidwiz on Database node first. We need to give all information for our db node and apps node. Once the installation on DB node completes, our database and listener would be ready.
























2) There would be a configuration file created on DB node ($ORACLE_HOME/appsutil/conf_.txt). Please copy it to application node as it would be needed during installation. 

3) Now we need to kickoff rapidwiz on application node.




Please provide the path of configuration file copied in step 2.

Oracle Workflow Services in Oracle Applications are encountering problems.The workflow components are not starting when I was trying to start up the services from front end web-form using system administrator responsibility.These services appear with a Target value of 1 and an Actual value of 0. Even I tried from Concurrent>Manager>Administer form but still these were not starting.

$FND_TOP/patch/115/sql/fndssouu.sql USER_NAME

Apart from setting the FND_USER.USER_GUID value to NULL, this script also flushes the workflow entity cache for the user.

When Autoconfig is executed in EBS/Oracle Apps it creates various configuration files which are created from the template files.
Some time we might need to find the template file associated with these conf file to customize these templates and avoid autoconfig to use the default ones.

Below are the few important points to be remembered.

• The AutoConfig template file cannot be customized if the "LOCK" keyword appears in the template file.
• AutoConfig ignores custom template files that are marked with "LOCK”.
• Customization of Template File must be done on both Patch & Run File system.

We can use below query to check the session details.

Query:


select s.ECID ,s.inst_id, s.SID,s.SERIAL#,p.spid,s.status,s.machine, s.ACTION, s.MODULE, s.TERMINAL,s.sql_id,s.last_call_et,s.event, s.client_info,s.PLSQL_SUBPROGRAM_ID,s.PROGRAM,s.client_identifier
, ( SELECT max( substr( sql_text , 1, 40 )) FROM gv$sql sq WHERE sq.sql_id = s.sql_id ) AS sql_text
, ( SELECT object_name FROM dba_procedures WHERE object_id = plsql_entry_object_id AND subprogram_id = 0) AS plsql_entry_object
, ( SELECT procedure_name FROM dba_procedures WHERE object_id = plsql_entry_object_id AND subprogram_id = plsql_entry_subprogram_id) AS plsql_entry_subprogram
, ( SELECT object_name FROM dba_procedures WHERE object_id = plsql_object_id AND subprogram_id = 0) AS plsql_entry_object
, ( SELECT procedure_name FROM dba_procedures WHERE object_id = plsql_object_id AND subprogram_id = PLSQL_SUBPROGRAM_ID) AS plsql_entry_subprogram
, 'alter system kill session ' || '''' || s.SID || ',' || s.serial# ||',@'|| s.inst_id||''''|| ' immediate;' kill_session
from gv$session s ,gv$process p
where
--client_identifier like '%HIMANSHU.SINGH%'
--s.ecid like '%ZnHWOPoUDWbG%'
-- sid=4361
--p.spid='1196'
--s.program like '%ICM%'
and p.addr=s.paddr
and p.inst_id = s.inst_id
;


Note: Un-comment the condition which ever is required.

We can use below query to find Patch Set Level in Oracle  E-Business Suite.


Query:

select
abbreviation
,codelevel
from
ad_trackable_entities
where
abbreviation in( 'ad','txk','fnd','fwk','atg_pf','icx' )
order by

abbreviation;

We can use below query to  find out the patch level of any product you have installed in e-Business Suite


Query:

sqlplus apps/

 SELECT substr(APPLICATION_SHORT_NAME,1,8) product,
substr(PRODUCT_VERSION,1,14) version,
substr(PATCH_LEVEL,1,11) patch_level
FROM fnd_application a, fnd_product_installations p
WHERE a.application_id = p.application_id
ORDER BY application_short_name;

1. License the product in License Manager.
2. Generate product related components by ADADMIN.

• Login to E-Bisuness Suite.
• Navigate to Oracle Application Manager > License Manager.
• Click on ‘Product’ link under ‘License’ tab.
• Select ‘License Application Product’ and ‘Continue’.
• Check the product you want to license and complete the action in License manager.
• Now the product is licensed in system, but not ready to use.

• Login to Application server with applmgr user.
• Set environment file.
• Run ADADMIN and choose below options:
• Option 1 – generate Application Files Menu >

• Return to Main Menu and choose Option 3 – Compile/Reload Applications Database Entities Menu >

• Return to Main Menu and exit from ADADMIN.
• Run autoconfig.

Now we can successfully use the new product.

We have to follow below steps for enabling India Localization.

STEPS

1. Click System Administrator ---> Oracle Applications Manager -->License Manager ---> Country-specific Functionalities ----> Select Singapore ----> Click Next ----> Click Submit ----> Click Ok.

2. Check the India Localization licensed or Not
Click Syatem Administrator ---> Oracle Applications Manager --> Licensed Products ---> check Status of JA-Asia/Pacific Localizations licensed or Not. If status is licensed means India localization is enabled

3.
Go to $JA_TOP/patch/115/driver/
[oracle@funoracleapps driver]$ pwd
/u01/TEST/apps/apps_st/appl/ja/12.0.0/patch/115/driver
[oracle@funoracleapps driver]$ ls
ja12axdo.drvx jai5188052.drv

4.  Enable the triggers
Go to /u01/TEST/apps/apps_st/appl/ja/12.0.0/patch/115/sql
Compile the files (Path: $JA_TOP/patch/115/sql)

                              a. jai_enable_trg.sql
                        
Connect sqlplus apps user

In this post I am going to share the steps for installation of SQL Developer on Linux Mint OS or Ubuntu.

SQL developer will require to jdk as pre-requisites.

Steps:

1. Install jdk 8 or above. 

sudo apt-get install openjdk-8-jdk

It will be installed in below folder

/usr/lib/jvm/java-8-openjdk-amd64

2. SQL Developer which we wil download from Oracle Website would in rpm format. I am going to use alien tool to covert it in debian(deb) format.

sudo apt-get install -y alien

3. Convert the SQL developer rpm to debain format.

himanshu@himanshu-ThinkPad-T430 ~/Downloads $ ls -ltr sqldeveloper-19.2.1.247.2212.noarch.rpm
-rw-rw-r-- 1 himanshu himanshu 420128668 Sep 18 23:46 sqldeveloper-19.2.1.247.2212.noarch.rpm


himanshu@himanshu-ThinkPad-T430 ~/Downloads $ sudo alien sqldeveloper-19.2.1.247.2212.noarch.rpm

Once done we can see below deb file.
