How to: Start SQL Server with Minimal Configuration

Leave a reply

When you encounter configuration problem that prevent SQL Server from starting, you may need to start an instance using the minimal configuration option. This is the start up option -f. Starting an instance of SQL Server with minimal configuration automatically puts the server in single-user mode.

Kindly not what you can do when you start an instance of SQL Server in minimal configuration mode, as below:

• Only a single user can connect, and the CHECKPOINT process is not executed.
• Remote access and read-ahead are disabled.
• Startup stored procedures do not run.

After the server has been started with minimal configuration, you should change the appropriate server option value or values, stop, and then restart the server.

a way to convert a .tib-Image to a VMware virtual machine without the VMware Converter.

Instructions: virtualization Acronis tib image in VMware Player without VMware Converter 

Preliminary 

Why not use the VMware Converter? 
VMware Converter Standalone client can not restore Acronis Images. The server can, but unfortunately it was on my Windows 7 host difficulties with the connection to the locally installed server, so I was the Image with access to the tib file not recognized at an impasse steckte.Selbst; probably the Acronis version with which this image was created, not supported. Why not return back up the image from the host via a network share or a USB drive? With Acronis True Image Home 10 (not 2010), the predecessor of Acronis True Image 2009 can not access from Windows 7 provided network resources to. From True Image 2009 is possible. In addition, True Image 10 crashed in accessing the USB hard drive, so that this way was blocked to existing tib image. In a new VM virtualization of an existing system to achieve, of course, other ways as possible. Benefits of the procedure described here , you will also work • if access to a tib image due to lack Acronistreiber via network or USB devices is not possible • without installation of the VMware converter • without installing additional software, no network and optical drive, if the ISO prepared with the tib image and the Acronis Recovery Image and everything stores together with the VMware Player on a USB hard drive , the ISO with the tib image may still be on a USB or network drive, as in the procedure described here of VMware Player the file from the USB or network drive makes it accessible and not a driver of Acronis True Image. Prerequisites / preparations for virtualization requires: • VMware Player (with the VMware workstation does this approach of course) • ImgBurn (Freeware) http: //www.imgburn.com/ (or any other burning software that can create large ISO images) • Full backup as a * .tib file a division into smaller units is not required. • Sufficient hard disk space on the target computer for the VM to the vmdk, take the .tib file and the ISO image which is three times as much hard disk space is required as the system to be virtualized is occupied. • Acronis True Image Recovery medium (preferably as a .ISO file) , if necessary , Create the appropriate tool from Acronis. Caution: The medium / ISO image must be of the same Acronis version (or higher), such as those with which the disk image has been created. A physical medium requires longer charging times and, of course, an appropriate drive on the host. Step 1: * .tib file in * .iso file convert 1. ImgBurn start . 2 If necessary, about fashion / EZ Mode Picker menu select (The EZ Mode Picker is usually started automatically at startup) . 3 Option "Create Image file from files / folders" Select . 4 Right in the "Options" in the "File System" UDFauswählen . 5 In "Advanced" tab, open the tab "Restrictions" and then the "Allow Files Exceeding Size Limit" to "Multiple extents" questions . 6 Left click below on the icon / button for Image creation . 7 Select the location and name of the image file . 8 If necessary, Choose label for ISO and click the dialog with the OK Summary Step 2: VMware machine for the image create . 1 Call VMware Player and select "Create a New Virtual Machine". . 2 Option "I want to install the operating system later" select . 3 The Select the .tib secure operating system . 4Designate VM and specify location . 5 Sufficiently large virtual hard disk for the rückzusichernde System Create . 6 Button "Customize Hardware" button . 7 By selecting the pre-configured CD / DVD drive "Use ISO image file" to the ISO with the .tib file mount . 8 About Button create "Add ..." an additional CD / DVD drive and for it to "Use ISO image" the ISO of Acronis Recovery CD mount (recommended) or specify a physical drive for the additional CD / DVD-drive and the Acronis Recovery medium load (requires longer charging times and, of course, a corresponding drive)


Note: The order of drives intended to be booted from which Image. In default drive so the ISO must be mounted with the Acronis disk image. The VM boots namely behind the additionally created drive.
9. Create a virtual machine with "Finish" to complete Step 3: VM Image Restore . 1 VM restart . 2 VM boot from the Acronis Recovery CD . 3 True Image (full version) Select . 4 Restoring click . 5 CD / DVD drive with the .tib file filter . 6 Select .tib file . 7 Perform the Recovery After restoring all the drivers are automatically found and installed. VM-Ware Tools can be installed and unnecessary drivers and the like are removed. Notes The idea for this approach comes from here . This forum is apparently no longer active (Last post December 2009). But that described therein Tool Folder2Iso obviously can not create oversized Images and failed at creating the ISO image with an approximately 50GB large tib file (without error message!). Test environment: virtualization of an IBM T43 (80GB HDD, 60GB is) on a current PC (i7, 8 GB) with Windows 7 Home Premium 64-bit successful and lasted for about 1 hour until the first successful boot.

• Antivirus
• AppLocker in “Deny” Mode (or another technology that does Application Blacklisting)
• AppLocker in “Allow” Mode (or another technology that does Application Whitelisting)
• Auditing (especially of implemented security controls)
• Forensic capture and analysis of host-based artifacts (filesystem, network, registry, etc.)
• Forensic capture and analysis of memory-only artifacts

很多人在工作上都會碰到這個困擾：「我很想專心地工作，可是要迅速集中精神並不太容易。」然而，保持高度的專注力，不僅可以提升工作效率，面對問題時也能冷靜思考，將自己的實力充分發揮出來。要提高專注力，在職場上有更好的表現，可參考以下5個方法：

1.目標明確：認真思考「自己想做什麼事情」「想過什麼樣的生活」「如何才能讓自己表現更好」等等問題，並且找出明確的方向，這些目標將會根植在潛意識中，成為維持專注力的基礎。

2.養成閱讀的習慣：在一定時間內讀完一定數量的書籍，可以大幅提升專注力。閱讀也可以激發想像力，並與現實生活進行結合，創造新的思考方式。無論是行動或思考，想像力都是關鍵，所以擁有靈活想像力就是好的工作能力。

3.擬定計畫、預先演練：如果能夠明顯看出工作進度，便能提高工作專注力。因此，不妨在晚上睡覺前，先規畫隔天的工作事項，並且依照緊急程度和重要程度排出優先順序；次日起床後便按照清單逐步完成工作。如此，便能實際感受工作正在推進，因而產生自信和幹勁，進一步提升專注力。

在規畫進度的同時，也要把「預計處理時間」納入考量，因為在時間壓力下，不但能夠訓練情緒的穩定度，專注力也會異常集中。另外，寫下工作的預定執行步驟，並按照筆記內容在大腦中演練，也是培養專注力很好的練習。因為大腦會將「想像情況」模擬為「實際狀況」，所以持續在腦中復習流程，就相當於反覆地進行工作，可以讓實際運作更加熟悉順暢。

4.培養「沒來由的自信」：人們很容易會對自己某些失敗經驗，賦予負面評價；而這些不愉快的想法，又常會在進行新工作時浮現腦海，干擾思緒。然而，事情的好壞利弊並沒有一定的評判標準，端視自己決定用什麼樣的態度來面對，或是如何改善這樣的處境。

所以，為過往的挫敗體驗，輸入正面的想法，鍛鍊自己「沒來由的自信」，就能在展開新工作時，擺脫不好經驗的牽絆，全心投入。

5.自我暗示：文字或語言，都可以控制自我意識。所以，讓自己身邊圍繞著正向積極的語言，不受外界或情緒的影響，便會慢慢改善專注力。例如，「不論在工作或生活，我的專注力都愈來愈好。」或「每一天我都變得更好。」（本文取材自《一定做得到的「超」專注力》，商周出版。整理／陳立唐）

[會念書]十五個學習技巧，迅速集中注意力

 自設"上課"鬧鐘

我們從小就在學校養成「聽到鐘聲代表要開始上課的習慣」，而利用這樣的習慣，預先設定在休息時間結束後的鬧鐘，也能夠讓自己更快速地進入狀況。


大腦暖身操

在讀書前先瀏覽當天需完成的項目；反問自己有哪些未完成的計劃；要讀的內容在整個科目體系中的定位為何，或者哪個部份是最大的弱點及障礙等等，為大腦進行學習暖身，就能更順利地進入學習狀態。（萬事起頭難，三十秒進入讀書狀態）


要告一段落時提前結束

當學習時段將要告一段落，或者是因此產生查閱相關資料的好奇心時，乾脆地就此打住，便能在心中產生「想要快點解決」的期待，在休息時間結束後能以很高的學習情緒進入狀況。


場地獨立或場地依賴

在心理學上有所謂的「場地獨立型」，指人不容易受環境因素的干擾與影響，便適合在家讀書；而「場地依賴型」容易受到環境的影響，便適合在圖書館或自修室讀書。


模擬考場氣氛

即使是場地獨立型，也能在圖書館或咖啡廳之類的場所念書，利用人群來想像前後左右都被考生包圍，模擬在考場的緊張感來提升專注力。 同時，也能訓練如何在嘈雜的環境中集中精神。


朝三暮四讀書法

假設原本的計劃是「六十分鐘的讀書時間連接十分鐘的休息時間」，便可更動為「四十五分鐘的讀書時間、十五分鐘的緩衝和十分鐘的休息」。如此一來，經過限縮的時間便會產生如同考試臨場時的「急迫感」，從而發揮出在考試時才擁有的高度專注力。（讀書計劃(三)：〝朝三暮四〞讀書法）


反向思考

要是學習環境沒有良好的讀書風氣，與其抱怨，倒不如反向思考，希望因為自己的存在而連帶提升整體環境的程度；在越容易讓人動搖的環境，更要專注於做出良好的榜樣。


命令大腦

當決定要專心唸書時，腦中的扁桃核可能會產生痛苦或煩躁等訊息，這時只要大喊或默唸關於「專注」的詞語，便能活化額葉聯合區，提升它對扁桃核的領導能力，徹底執行專注的命令。（以科學方式獲得超級專注力）


指點集中

人類對於棍棒或細長形式的物體就具有特別高的意識焦點，所以用手指指點閱讀文字，便能強迫集中焦點，再度提高專注力。（以科學方式獲得超級專注力）


一心不二用

雖然我們可能習慣同時做兩件事，但大腦本質仍然是序列性的處理每一件事。研究指出，一個人作業被打斷後，他要多花百分之五十的時間才能完成這個作業，而且他的出錯率也會增加百分之五十。（腦科學系列：高注意力等於好學習）


信心喊叫

發自丹田的喊叫能促使腎上腺素的分泌，除了增強肌肉的力量也能夠提高專注力。
（認識腎上腺素──舒解壓力的讀書法）


適度休息

當學習經過一段時間，大腦自然會發出「想要休息」的訊號而無法集中精神，這時如果忽略警訊並強迫學習，只會產生事倍功半的結果。（對症下藥，讀書缺乏幹勁三大因素 ）


吃飽不念書

剛進食完畢時，身體為了消化會將血液集中於胃部，腦細胞活動便會遲緩，集中力自然下降。（不該唸書的三個時段：剛吃完、吃太飽、吃太少）


飢餓不讀書

當人體處於持續的空腹狀態，身體為了自保會分泌出能使血糖值上升的荷爾蒙，其中將帶來焦躁感腎上腺素也包括在內。（認識腎上腺素──舒解壓力的讀書法）


裝潢有訣竅

在書桌座位的後方最好有實牆可倚靠，才能夠環顧房間動態，避免背門而易受風吹草動的影響。(簡單提升專注力的書房裝潢術)
