Attempt to connect to a data store that has been manually unloaded from R AM

Timesten in-memory Database :-

ttisql DSN_NAME

ttIsql (c) 1996-2005, TimesTen, Inc. All rights reserved.
Type ? or "help" for help, type "exit" to quit ttIsql.
All commands must end with a semicolon character.
connect "DSN=DSN_NAME";
707: Attempt to connect to a data store that has been manually unloaded from R
AM
The command failed.

This should be easy to resolve. A TimesTen datastore (physical database), which is what a DSN points at, has a property called its 'ramPolicy' The default value for this is inUse which means that TimesTen will load the datastore into memory whenever it is being used.

Solution :

ttAdmin -ramload DSN_NAME

TT6003: Lock request denied because of time-out

Trying to create cache group lead to the below error :-

java.sql.SQLException: [TimesTen][TimesTen 11.2.1.4.0 ODBC Driver][TimesTen]TT6003: Lock request denied because of time-out
Details: Tran 143.23106 (pid 19946) wants Sn lock on rowid BMUFVUAAAAxogAALDp, table SUBSCRIBER. But tran 144.67398 (pid 19946) has it in Xn (request was Xn). Holder SQL (select ID,identifierType,identifiervalue,subscriberId,groupName,siid from subscriptionidentifie...) -- file "tindex.c", lineno 4277, procedure "sbTixNext()"

After check the Timesten parameter found the issue was with LockWait


Lockwait :- Allows an application to configure the lock wait interval for the connection.

LockWait may be set to any value between 0 and 1,000,000 inclusive to a precision of
tenths of a second. The default is 10 seconds.

Actual lock wait response time is imprecise and may be exceeded by up to one tenth of
a second, due to the scheduling of the agent that detects timeouts. This imprecision
does not apply to zero second timeouts, which are always reported immediately.

Linux : Cannot Access .... Input/output error

/bin/ls: reading directory .: Input/output error
total 0

The above error indicate that i cannot access to the specific file on Linux, Delete not working. with root user as well.
so the error is not a problem to delete files, it's a problem about the file system itself and/or an hardware problem, but before announce that it's hardware issue :) try the below solution :-

 Option #1:-

use command dmesg.

(display message or driver message) is a command on most Linux- and Unix-based operating systems that prints the message buffer of the kernel. Read about that command here

Option #2 ( worked for me)

Use Fsck command to detect filesystem error and fix it.

How !!!

  1.  First Umount File system ( that file located ). Using Umount command if it's not able to un mount the file system use lsof command or fuser to check which user using this filesystem.
  2. run the fsck -y /dev/................. 
  3. mount file system again.
Fsck Command here

  • New Zealand.
Sure during most of these conferences i was organizing RAC ATTACK Event around the world and simply it successful year for this amazing event.

Don't forget the webinar as well. 

I have to mention One of the most amazing event all the time which is oracle open world, This is was my first time in SF OOW I met most of the people in oracle community i will try to mention all of them but i am sorry if i forgot someone :-

i enjoyed my time hanging out with ACE and ACED, a lot of activity to do in OOW such as presentation, Concert .. etc.

don't forgot this year i wrote three articles to different magazine and i still have a lot of different topics to share, My Blog  i wrote blog post related to fusion middleware and Timesten in memory database most of these article what i faced in my real life challenging but amazing at the same time.

i was the first one in the middle east ( Jordan ) who appeared in Oracle Magazine Peer to Peer Thanks for Oracle ACE program i am really proud to be member of this amazing community.

I created magazine on flip-board that collect all the good articles posted by oracle community and share under one place and i am contribute in another one  Thanks for my friend Leighton Nelson.
the both magazine are simply amazing both sharing different idea.

I also passed Fusion middleware exam and upgrade my OCP certification. 

Finally I am really proud of one of the most achievement for this year which is created JAOUG ( Jordan Amman Oracle user group) i am working too hard to make this group success, i would like to give special thanks to Heli Helskyaho who supported me and gave me an idea to launch the group when i was in OOW.

Happy new year and healthy 2015.

During the Holiday I was working on my mini Lab and Upgrading the Server i want to use ESXI 5.5 this time,usually the built-in Ethernet card  Intel or Realtek ( Mine ) while the installation i faced an issue that ESXI 5.5 doesn't identify my Ethernet card and the installation failed.

To solve this issue the normal ESXI iso will not work, because of this you have to create something called ESXI custom ISO using Software called ESXI customizer.

Download it from here.

You make this software work you need to install the original ESXI ISO.

Download it from here.

and The most important thing which is the driver that you need it for Ethernet Card, the driver usually depend on the PC just like to told you before I am using Realtek and you can download :-


  • net-r8168+r8111e From here.
  • net-r8169 From here.

Now you have all the software,  Original ESXI , Driver and the customizer.
Open the ESXI customizer new GUI screen will be open with three box like the below.

Clik here to view.


Now RUN Button and Check the output Directory Burn the ISO and This is should solve the issue.

Unable to Ping ESXI 5.5 Host

while i am continue working on my  Lab and configure ESXI i faced another problem and took 2 days to solve it maybe someone faced this issue but this will help other people as well.

The problem description like this :- after assigned IP to the server i want like normal people connect to this server using my laptop but simply when trying to ping :-

"Detestation unreachable" 

I thought at first it was my network card issue and maybe it's not supported By ESXI, But this is not valid option because the weirdest part in this issue was when restart the server and ESXI loading the services i was able to ping without any problem then the message appeared again.

Image may be NSFW.
Clik here to view.

as you see from the above screenshoot ping then not ping !!!!!


The solution very simple i start missing with BIOS options and found new option there called "Network Stack" all you have to do is enable this option and link to IPV4.

Sometimes you will be not be able to check the database out of the office, sick ....

Regarding to oracle documentation :-

The notification system allows you to notify Enterprise Manager administrators of alerts, policy violations, and the status changes of job executions. In addition to notifying administrators, the notification system can perform actions such as executing operating system commands (including scripts) and PL/SQL procedures when an alert is triggered.

Before Enterprise Manager can send e-mail notifications, you must first specify the Outgoing Mail (SMTP) servers to be used by the notification system. Once set, you can then define e-mail notifications for yourself or, if you have Super Administrator privileges, you can also define notifications for other Enterprise Manager administrators.

For More about E-Mail Notification Read here.
