AWS using Ansible? Yes, it's possible!

-
  Although, I've used Ansible extensively for a lot of automation and orchestration tasks, using Ansible for AWS was indeed, a new territory for me.  This turned out to be a blessing, since along with using Ansible for AWS tasks, I also learnt how to use WSL (Windows Subsystem for Linux) on a Windows machine. Though WSL's been around for some time, I still hadn't come around to using it since I was mostly using my Macbook pro. Not anymore, though!  Anyway, I have listed below the steps to: Install WSL on Windows 11 23H2 patch Install AWS CLI on Ubuntu 22.04 (Exact version - 22.04.3 LTS) Install Ansible and the amazon.aws collection Use AWS CLI to get the list of  VPCs in the region - us-east-1 (or a region of your choice) Create a python file/script to get the list of VPCs in the region - us-east-1 (or a region of your choice) Create an Ansible playbook to get the list of VPCs in the region - us-east-1 (or a region of your choice.   You may download the complete installat

Clone database home (clone.pl) deprecated in Oracle 19c

-
Back to blogging, at last. Well, this time it's about clone.pl.

Background about clone.pl

The easiest way to install a patched and up-to-date Oracle home is to physically copy it from a source server (that is already patched and up-to-date) and use clone.pl on the target server so that the binaries are linked to the target server's OS binaries (like gcc, libstdc++ etc.,), registered with the Oracle Inventory etc.

The alternative to clone.pl is to:

  1. Install Oracle binaries using GUI or command line
  2. Apply the latest patchset (PSU/CPU patches)

As you can see now, clone.pl is really useful in order to cut down time to build a database in a new server.

More about clone.pl here and here (12c), here (18c).

However, in Oracle 19c, Oracle has officially said - "Starting from oracle database 19c ,the clone.pl script is deprecated  and can be removed in a future release. Hence, Oracle recommends that you use the software-only installation option, available in the database installer, instead of clone.pl to clone your database.This document provides instructions on how to clone oracle home using gold image concept ." (2565006.1)

Here I list the simple steps to create a gold image and then cloning the target oracle home using that gold image. Hope it helps.

STEP 1: Create gold image zip file

 

Once the 19c software is installed and patched, use the below command to create the gold image zip file:

 

$ $ORACLE_HOME/runInstaller -silent -createGoldImage -destinationLocation <DESTINATION_DIRECTORY>

Launching Oracle Database Setup Wizard...

 

Successfully Setup Software.

Gold Image location: <DESTINATION_DIRECTORY>/db_home_2020-03-30_07-38-54AM.zip

 

STEP 2: Copy gold image to the target location


$ rsync -aS <DIRECTORY_OF_GOLD_IMAGE_ZIP>/db_home_2020-03-30_07-38-54AM.zip <TARGET_USER>@<TARGET_SERVER>:<TARGET_DIR>

 

STEP 3: Unzip the gold image under $ORACLE_HOME

 

Unzip the gold image under the ORACLE_HOME directory (/oracle/product/19.0.0):

 

$ cd $ORACLE_HOME

$ unzip -d $ORACLE_HOME <DESTINATION_DIRECTORY>/db_home_2020-03-30_07-38-54AM.zip

 

 

STEP 4: Execute runInstaller to clone the target ORACLE_HOME

 

Execute runInstaller command to clone the target ORACLE_HOME. Ensure to use the runInstaller binary directly under $ORACLE_HOME.

 

$ ${ORACLE_HOME}/runInstaller -silent -responseFile <PATH_TO_RESPONSE_FILE>

$ ${ORACLE_HOME}/runInstaller -silent -responseFile install.rsp

 

RESPONSE FILE CONTENTS:

 

$ cat install.rsp

oracle.install.responseFileVersion=<PATH>/rspfmt_dbinstall_response_schema_v19.0.0

oracle.install.option=INSTALL_DB_SWONLY

UNIX_GROUP_NAME=dba

INVENTORY_LOCATION=<ACTUAL_INVENTORY_LOCATION>

ORACLE_HOME=<ACTUAL_ORACLE_HOME_LOCATION>

ORACLE_BASE=<ACTUAL_ORACLE_BASE_LOCATION>

oracle.install.db.InstallEdition=EE

oracle.install.db.OSDBA_GROUP=dba

oracle.install.db.OSOPER_GROUP=dba

oracle.install.db.OSBACKUPDBA_GROUP=dba

oracle.install.db.OSDGDBA_GROUP=dba

oracle.install.db.OSKMDBA_GROUP=dba

oracle.install.db.OSRACDBA_GROUP=dba

Solution to "End Program - WMS Idle"

-
Image
Though this topic is unrelated any Apps DBA topics, I found it necessary to share the solution so that everyone benifits out of it ! Issue: I used to receive the below error message whenever I tried to shutdown windows XP. A rather vexing problem, no doubt. Cause: This message appears because when windows is trying to shutdown and end all the running processes, the WMS idle process keeps working. Thus an end-program message appears. The two most common reasons for this are: Scout service run by Nero 7 Microsoft Office Communicator 2005 Solution: The fix is simple, disable the Nero 7 scout service if it is enabled. For this, go to Start > All Programs > Nero > Tools > Nero Scout . On this screen , Uncheck Enable the Nero scout. This will fix the issue for most of the users, for the rest of you who are not using Nero are most probably getting this error because of Microsoft Office Communicator 2005. For that you need to either manually exit the communicator 2005 from the s

Modify retention period of workflow queues

-
Yesterday, there was a requirement to increase the retention period of WF_DEFERRED and WF_BPEL_Q so that the developers could troubleshoot issues involving business events. This can be done this way: 1. Check the retention period of existing workqueues. SQL> SELECT owner, name, retention FROM all_queues WHERE name LIKE 'WF%'; OWNER           NAME                                                RETENTION --------------- --------------------------------------------- ------------------------------ APPS                 WF_BPEL_Q                                                0 APPLSYS         WF_INBOUND_QUEUE                             0 APPLSYS         WF_OUTBOUND_QUEUE                          0 APPLSYS         WF_SMTP_O_1_QUEUE                           0 APPLSYS         WF_DEFERRED_QUEUE_M                        0 APPLSYS         WF_DEFERRED                                            0 APPLSYS         WF_ERROR                                           0 AP

Check if UTL_FILE and FND_FILE are working fine

-
Yesterday, while troubleshooting a vexing ORA-29280 error, I came across 2 useful PL/SQL anonymous blocks that can be used to test FND_FILE and UTL_FILE to find out whether they are indeed working fine. UTL_FILE set serveroutput on DECLARE file_location VARCHAR2(256) := '<first entry on utl_file_dir>'; file_name VARCHAR2(256) := 'utlfile1.lst'; file_text VARCHAR2(256) := 'THIS IS A TEST'; file_id UTL_FILE.file_type; BEGIN file_id := UTL_FILE.fopen(file_Location, file_name, 'W'); UTL_FILE.put_line(file_id, file_text); UTL_FILE.fclose(file_id); EXCEPTION WHEN UTL_FILE.INVALID_PATH THEN dbms_output.put_line('Invalid path ' || SQLERRM); WHEN OTHERS THEN dbms_output.put_line('Others '|| SQLCODE || ' ' || SQLERRM); END; / References: Metalink (MOS) Note ID: 261693.1 FND_FILE set serveroutput on exec FND_FILE.PUT_LINE(FND_FILE.LOG, 'THIS IS A TEST'); HTH.
