Testimony By Lizzy Desler. How to get your ex back fast! I was hurt and heart broken when a very big problem occurred in my marriage seven months ago, between me and my husband . so terrible that he took the case to court for a divorce. he said that he never wanted to stay with me again,and that he didn't love me anymore. So he packed out of the house and made me and my children passed through severe pain. I tried all my possible means to get him back, after much begging, but all to no avail. and he confirmed it that he has made his decision, and he never wanted to see me again. So on one evening, as i was coming back from work, i met an old friend of mine who asked of my husband .So i explained every thing to him, so he told me that the only way i can get my husband back, is to visit a priest, because it has really worked for him too. So i never believed in spell, but i had no other choice, than to follow his advice. Then he gave me the Email address of the priest whom he visited. Pristbacasim2000@gmail. com. So the next morning, i sent a mail to the address he gave to me, and the priest assured me that i will get my husband back the next day. What an amazing statement!! I never believed, so he spoke with me, and told me everything that i need to do. Then the next morning, So surprisingly, my husband who didn't call me for the past 7 months, gave me a call to inform me that he was coming back. So Amazing!! So that was how he came back that same day, with lots of love and joy, and he apologized for his mistake, and for the pain he caused me and my children.

(In response to stating VMware lun sizing best practice) Why would volume management of smaller luns result in lower performance than a large lun (meta)?

1 Answers

Primarily due to larger amount of locking needed, but also due to immaturity of ESX volume management. Using few metas (luns) striped across a similar number of spindles, and similar port use, as the many smaller devices provides the same physical I/O performance with less overhead in ESX. Less

Explain the difference between a FUNCTION, PROCEDURE and PACKAGE.

1 Answers

A function and procedure are the same in that they are intended to be a collection of PL/SQL code that carries a single task. While a procedure does not have to return any values to the calling application, a function will return a single value. A package on the other hand is a collection of functions and procedures that are grouped together based on their commonality to a business function or application. Less
