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 comple...

Rebuild reporting database

-
In one of my previous posts , I had spoken about creating a reporting database that is editable at the same time, though the edits are transient. The last month, I faced an interesting situation wherein we had to rebuild this reporting database. In this post, I'll talk about rebuild the reporting database when it is corrupted. Context The standby database has been corrupted due to a server crash and needs to be rebuilt from the primary database. Solution I followed the steps mentioned in this post about creating a physical standby database. The steps in the pre-requisites can be skipped because they are already existing. The rest of the steps hold good!

WF Mailer Error - Unable to make a connection with the user and responsibility

-
Yesterday, I faced an issue while starting WF Mailer in a development instance. It was a clone from production and was recently patched, during the course of which, autoconfig was also run. Without further ado, let me explain the problem and the solution: Issue Receiving below error while trying to start WF Mailer: [Mar 30, 2010 4:22:44 AM CDT]:1269940964344:Thread[BES Dispatch Thread,5,main]:0:-1:suomt32l:10.6.71.100:-1:-1:ERROR:[SVC-GSM-WFMLRSVC-801965 : oracle.apps.fnd.cp.gsc.SvcComponentContainer.handleComponentEvent(int, String, String)]:Could not start component; performing rollback -> oracle.apps.fnd.cp.gsc.SvcComponentException: Validation failed for the following parameters -> >>>>>>>>>>>>>>{FRAMEWORK_USER=Unable to make a connection with the user and responsibility}.<<<<<<<<<<<<<< Parameters were -> {INBOUND_MAX_IGNORE_SIZE=1000, INBOUND_MAX_LOOKUP_CACHE_SIZE=100, ATTACH_IMAGES=Y, ALL...

Quirky 11i Apps Patch queires

-
Long time since I blogged. I was a bit busy with my vacations and work! Anyway, check out my travelogue , if you are interested enough. This time, I plan to write about a few quirky and rarely used queries to find out whether a patch is applied. Method 1 Check Patches applied from Oracle Applications Manager (OAM). a) Connect to OAM: http://hostname.domain:port/servlets/weboam/oam/oamLogin Go to Site Map-->Maintenance-->Applied Patches Enter Patch ID and press 'Go' See if Patch is returned. Method 2 Use 'adphrept' utility documented in Metalink Note:181665.1, section 'Retrieving information on patches or files that have been applied via adpatch'. $AD_TOP/patch/115/sql/adphrept.sql (available on admin and web nodes in multi tier APPL_TOP) (1) Patch History report usage: $AD_TOP/patch/115/sql/adphrept.sql <query_depth> < bug_number or ALL> <bug_product or ALL> \ <end_date_from (mm/dd/rr or ALL)> <end_date_to (mm/dd/rr or ALL)> \...

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....

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              ...

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: Install Oracle binaries using GUI or command line 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 installe...
