Gmail | How to always open “English” interface

Hello guys

I’m always using FireFox browser with no history saved. This potentially helps me from the browser “Remembering” my “hostile” activities.

As I live in Kuwait, this has a downside. Google decided to launch the local language page (Arabic) as soon as I try any of the Google applications like search or email.

I don’t pretty much care about the search part, as soon as the results are loaded, I am given an option to switch the language to English.

However, the email thing is NOT that easy. I have scroll few kilometers down, do a guess work with the language drop down and again on the login page, have to select English as language.

Recently I did some minor adjustments with the URL & figured out a short link that will definitely load the English Gmail logon screen ;)

This link is effective as on today (2nd May 2019). Please don’t visit this page after few years & complain about it is not working.

regards,

Uninstallation of APEX from a default Oracle 11gR2 database

Matthias Hoys

Environment: Oracle Linux 6.2, Oracle database 11gR2 11.2.0.3, APEX 3.2.1

If you use the graphical dbca utility to create a new Oracle 11gR2 database, you will have noticed that this includes Application Express by default, and there is no way to deselect that option (to my knowledge) during the installation process. Here I will explain how you can remove APEX from the 11g database after the installation.

First, you need to figure out what version of APEX is installed. You can do this by looking at the name of the APEX_xxxxxx schema, or by executing the following query (with user SYS as SYSDBA):

SQL> select version from dba_registry where comp_id=’APEX’;

VERSION
——————————————————————————–
3.2.1.00.12

Next, you need to download the exact same version of the software (in this case: version 3.2.1) from Oracle’s website. The last version of APEX as of writing is 4.1.1, but the uninstallation won’t work with…

The OLE DB provider “OraOLEDB.Oracle” for linked server “” returned a “NON-CLUSTERED and NOT INTEGRATED” index “” with the incorrect bookmark ordinal 0

My Blog

The good thing with linked servers is, you can write queries to fetch the data from a remote server (via linked) in your sql procedures and more.

We happened to test the connectivity of a oracle server due to an upgrade. When a new Linked server connection is created using the UI and ran a sql to fetch the data from a oracle table, Sqlserver connection throw ed an error message

Msg 7319, Level 16, State 1, Line 1
The OLE DB provider “OraOLEDB.Oracle” for linked server “ORACLEUAT” returned a “NON-CLUSTERED and NOT INTEGRATED” index “O_AD_EM” with the incorrect bookmark ordinal 0.

The solution to this problem is to force the oracle indexes to be ignored by changing the option “Index as access path” on the OraOLEDB.Oracle provider.

Oracle Application R12|Payables|FRM-40735 WHEN-VALIDATE-ITEM trigger raised unhandled exception ORA-01403

Hello guys

Recently one of our accountants forwarded me a screenshot, that was showing “FRM-40735 WHEN-VALIDATE-ITEM trigger raised unhandled exception ORA-01403” while he was trying to enter invoices against a “NEWLY” created vendor/supplier.

posterror

Our Oracle Application R12 (12.0.6) is considered 99.99999% stable, without a single technical or functional issue that really become a show stopper throughout last many years.

Well, this particular issue looked perplexing as it was not dealt by Oracle Application’s error reporting & slowly we started dwelling Oracle support documents those were dealing with the given forms error “FRM-40735 WHEN-VALIDATE-ITEM trigger raised unhandled exception ORA-01403”

Most of the documentations where mentioning about IBY duplicate pay party, which was not our case. Hence, I decided to open the associated form APXINWKB.fmb & located the WHEN-VALIDATE-ITEM trigger associated with the column “Purchase Order Number”. I couldn’t find any irregularities between an order that didn’t raise the error and this particular Purchase order did raise the exception, which was unhandled.

After two days of continuous attempts, I remembered that such errors happen in other forms modules when we had missing information for new vendors/suppliers. Must be due to a bug, there were times when site level details were NOT populated to organizations level details for a vendor/customer & I decided to go through all mandatory elements those were expected while creating a new vendor/supplier.

I sat with my colleague and we reached to “Payment Method”, and realized that the default payment method was not set for this particular vendor against the organization where we were getting this unhandled exception.

Once the payment method was set, the invoice was posted for the vendor successfully! So, if you come across these kind of unhandled exceptions across Oracle’s proprietary forms those deal with payments/invoices, prior exhausting yourself with cloning and patching, make sure you have all the mandatory elements for customer/vendors are properly filled in and assigned to all the organizations.

Hope this finding helps few consultants out there!

How to change the size of Online Redologs?

Uwe Hesse

change

Having just reviewed this article I can confirm that it is still valid also for 12c: The exact same commands can be used to change logfile sizes with that version.

If you deal with Oracle Databases for years on a daily basis like I do, you sometimes forget that things that seem elementary to you ain’t necessarily so for others, especially newbies in the Oracle realm. I noticed that when I saw some discussions in forums about redo logfiles and their sizes.

When I go back in time to 1998, that’s where I was the first time responsible for an Oracle Database (version 7, but some things never change). I inherited that Database from the previous DBA who did the setup, creating quite small log groups of a couple 100 KBs in size – which was not uncommon these days,  because Oracle templates mentioned that size as “medium”, if I…

Enable Database Enterprise Manager Console on Oracle EBS R12.1.1

I’m yet to check this one out. Reblogging to avoid losing the link among the ocean of bookmarks those I already have.

Joey Out Of The Box

First login as applmgr user, shutdown all application tier process using .
Login as oracle user to linux. Source the database environment.
Ensureis set in the init.ora for the
database using this command:

SQL> show parameter
REMOTE_LOGIN_PASSWORDFILE;

Create a password file using this command on linux:

Then execute this command:

(remember to change SID and port if needed).
You will be asked some question:

SYSMAN schema will be dropped and recreated.
While dropping the scema, database will be quisced.
Database sessions that blocking the quiescing process must be killed.
Use sqlplus to identify the sessions:

Make note on SID and SERIAL#.
Kill the session using this sql command:

(don’t forget to change SID and SERIAL#).
On create schema process you may need to increase the size of SYSAUX tablespace.
After the process completed you can access the enterprise manager on internet browser using this URL:

You may also have…

Oracle E-Business Suite R12 | SGA vs PGA vs NOT being a DBA!

Hi guys

I know the subject title is not very professional this time. Yet, I want to make a claim that I figured out something, for which I spent more than couple of years time and have followed up few Oracle community threads (without much interesting results)

We had to retired a hardware that was recommended by the Oracle EBS implementation partner, within 2 years once after we went online with the R12 instance. We had 10g 10.2.0.3 with the instance, things were getting messy and slow & the new support partner recommended for a better hardware.

I always had eyes on this retired server. It had Linux, hence we couldn’t come up with a practical requirement to integrate the Linux server with our Windows domain environment and it was kept switched off until the virtualization project came online.

We needed “something” to hold a copy of the EBS instance while it was being virtualized.

So, I cloned this machine & before continuing let me describe what this is hardware is like:

Processor:


Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 8
On-line CPU(s) list: 0-7
Thread(s) per core: 1
Core(s) per socket: 4
Socket(s): 2
NUMA node(s): 1
Vendor ID: GenuineIntel
CPU family: 6
Model: 23
Model name: Intel(R) Xeon(R) CPU E5420 @ 2.50GHz
Stepping: 6
CPU MHz: 1992.000
BogoMIPS: 4987.29
Virtualization: VT-x
L1d cache: 32K
L1i cache: 32K
L2 cache: 6144K
NUMA node0 CPU(s): 0-7

Storage space


[root@erp-bak ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sdj2 59G 12G 44G 22% /
tmpfs 9.7G 3.9M 9.7G 1% /dev/shm
/dev/sdj1 2.0G 325M 1.5G 18% /boot
/dev/sdj5 738G 531G 170G 76% /u01
/dev/mapper/mpathbp1 591G 320G 242G 57% /u02
/dev/mapper/mpathcp1 197G 38G 150G 20% /u03
/dev/sdf1 591G 70M 561G 1% /u04
/dev/sdi1 269G 59M 256G 1% /u05

in addition to the local disks this server have partitions mounted from a IBM SAN.

Once the clone was done, I realized that the instance was extremely slow & our part time DBA started making excuses like “See that’s why we are changing the hardware” (He had 2G SGA and 1G PGA with 20 job_queue_processes against nearly 1TB database)

I opened few discussions with Oracle communities and was pointed towards a tone of documents suggesting me how to fine tune the hardware and database for better performances. Actually nothing were applicable as I didn’t have much hands on experiences with a database & I couldn’t find a person who could really HELP me.

Then I started taking interest about database technology, which I should have years back & came across SGA/PGA and JVM etc & as I had an idle instance, started trying out whatever I have “learned” against it.

While doing the 11g R2 the hard way I realized that I can use AMM and forget about tuning different parameters for memory optimization. Well, still the goddamn instance lagged like hell & I was almost done with it!.

Few of the persistent issues were:

After a cold boot

  • The login form would load at client end after waiting almost 3-4 minutes, which gets faster during consecutive attempts.
  • It takes ages for to open the concurrent programs window
  • Our custom forms & LOVs lag to extremes and so on..

Even shutting down the instance for anything was turning into a nightmare as the database always took more than 15-20 minutes and I had to kill multiple processes manually in order to bring it offline!

Then on a different note, while trying to learn SQL learning I landed against an ask Tom thread, where the asker says “I have setup both SGA and PGA 3GB”, still the SQL runs slow…

I did a fresh clone. Our database was upgraded to 11g almost year back. The default clone had 1G for both SGA and PGA. I altered them with 3G and 3G & bullseye

I went back and altered the SGA and PGA with 4G which was 40% of the total physical memory available for the hardware. I did three shutdowns and restarts of the physical server, did a dozen application and database startup to confirm that what I am experiencing is NOT a once in bluemoon phenomena. Each of my attempt to shutdown the database gracefully were completed within few seconds, not a single time I had to kill the Linux processes to bring it down!

I modified one of the main forms for a custom application and changed few VIEW calls with better logic & I can’t be happier!

Now, said that, don’t rush to me saying “I also did 4G for SGA and PGA and moron I still have a slow instance”. There are many factors affecting the performance of your database and application & most important few are:

Age of your hardware, especially the spinning disks. The aged they are, the worse the performance is going to be as there is hell loads of I/O happens when you are accessing/processing the data from a database.

Recently I was going through a MS SQL discussion about Multi-Tenant architecture and one of the contributors were discussing about a hosting firm that keeps on changing their hardware once in 6 months. I think he was just BLUFFING! ;)

I hope someone gets benefitted by the minor finding I have made YESTERDAY (6th May 2018)!
