非ミラー環境に、ミラー環境でオンラインバックアップしたバックアップファイルをリストアする方法

これは InterSystems FAQ サイトの記事です。

こちらの記事では、非ミラー環境にミラー環境でオンラインバックアップしたバックアップファイルをリストアする方法をご紹介します。

手順は大きく分けて2つになります。


1.バックアップファイルからリストアを行う

2.データベースファイルのミラー属性を削除する



1.バックアップファイルからリストアを行う

以下は、^DBREST ユーティリティによる対話形式のリストア方法になります。

%SYS>do ^DBREST
                        Cache DBREST Utility
         Restore database directories from a backup archive
 
Restore: 1. All directories
         2. Selected and/or renamed directories
         3. Display backup volume information
         4. Exit the restore program
    1 => 2    // <-- <Enter> ミラー環境でバックアップしたバックアップファイルを、ミラー環境ではない環境にリストアする場合は、2 を選択する必要があります
              //     ※『1. All directories』を選択した場合、リストア対象はミラーデータベースのみになるため、ミラーでなければリストアはされません
Do you want to set switch 10 so that other processes will be
prevented from running during the restore? Yes =>   // <-- <Enter>
// Yes の場合、リストア中に他のプロセスがグローバルデータにアクセスできないように制御するスイッチ10を設定します。   
Specify input file for volume 1 of backup 1
 (Type STOP to exit)
Device: C:\Backup\FullDBList_20250402_001.cbk   // <-- バックアップファイルパス
This backup volume was created by:
   IRIS for Windows (x86-64) 2024.1
The volume label contains:
   Volume number      1
   Volume backup      APR 2 2025 09:50AM Full
   Previous backup    DEC 23 2024 12:21PM Full
   Last FULL backup   DEC 23 2024 12:21PM
   Description        Full backup of all databases that are in the backup database list.
   Buffer Count       0
   Mirror name        TESTMIRROR
   Failover Member    MACHINEA
Is this the backup you want to start restoring? Yes =>   // <-- <Enter>
Restoring a mirror backup but this system is not a mirror member
 
For each database included in the backup file, you can:
 
 -- press RETURN to restore it to its original directory;
 -- type X, then press RETURN to skip it and not restore it at all.
 -- type a different directory name.  It will be restored to the directory
    you specify.  (If you specify a directory that already contains a
    database, the data it contains will be lost).
 
c:\intersystems\iris\mgr\mirrordata\ (:mirror:TESTMIRROR:MIRRORDATA) =>   // <-- 同じで良ければ <Enter>
Directory c:\intersystems\iris\mgr\mirrordata\ does not contain a database
or it can't be accessed.
Do you want to create this database? Yes =>   // <-- <Enter> IRIS.datがないときは作成する
Do you want to change this list of directories? No =>   // <-- <Enter>
Restore will overwrite the data in the old database. Confirm Restore? No => y   // <-- y+<Enter>
***Restoring c:\intersystems\iris\mgr\mirrordata\ at 10:22:10
84 blocks restored in 0.0 seconds for this pass, 84 total restored.
 
***Restoring c:\intersystems\iris\mgr\mirrordata\ at 10:22:10
2 blocks restored in 0.0 seconds for this pass, 86 total restored.
 
***Restoring c:\intersystems\iris\mgr\mirrordata\ at 10:22:10
2 blocks restored in 0.0 seconds for this pass, 88 total restored.
 
 
Specify input file for volume 1 of backup following APR 2 2025  09:50AM
 (Type STOP to exit)
Device: STOP   <-- STOP+<Enter>

Do you have any more backups to restore? Yes => N   // <-- 他になければ N+<Enter>
Mounting c:\intersystems\iris\mgr\mirrordata\ which is a mirrored DB
  c:\intersystems\iris\mgr\mirrordata\ ... (Mounted)

There are mirrored DBs restored, please make sure the mirror
journal files are copied to a specific directory in order to
let system restore the journal records.
Please enter the directory contains the mirror journal files:
<C:\InterSystems\IRIS\mgr\journal\>?    // <-- 特になければ <Enter>
*** WARNING **** Failed to restore the journal records for the mirrored DBs
// バックアップからリストアした後、さらに現時点のDBまでミラージャーナルファイルを使用してキャッチアップするかどうかの選択
// バックアップ時点までで良ければ、そのまま<Enter>するとディレクトリ内にリストア対象のミラージャーナルがないため、上記Warningが出てリストアは終了する
%SYS>


2.データベースファイルのミラー属性を削除する

ミラー環境で取得したバックアップを、非ミラー環境にリストアすると、そのままではDB書き込みができません。
これは、リストアされたデータベースは、読み取り専用でマウントされるためです。
(ミラーデータベースについては、別ミラー環境やミラー構成でない環境にリストアすると読み取り専用になります)
この為、リストア完了後に以下の操作にてデータベースファイルのミラー属性を削除する必要があります。

手順は、以下のようになります。

%SYS>do ^MIRROR
This instance is not initialized as a mirror member

1) List mirrored databases
2) Remove one or more mirrored databases
3) Create a Mirror
4) Join Mirror as Failover Member  // ミラーが有効になっている場合、この設定が表示されます
5) Join Mirror as Async Member    // ミラーが有効になっている場合、この設定が表示されます
Option? 2    // Mirror DBからMirror 属性を削除します
There are xxx mirrored databases on this system
Remove (O)ne mirrored database, (A)ll mirrored databases or (Q)uit? <quit> A  // A + <Enter> すべてのMirror DBを対象とします
// ミラーDBが1つしかないときは以下のようになります。Yでミラー属性を削除します
// There is one mirrored database on this system
// Remove it? <No> // Y + <Enter>
Removing c:\intersystems\iris\mgr\mirrordata\ ...succeeded
:
Press <enter> to return to the main menu...  // <Enter> で抜けます
1) List mirrored databases
2) Remove one or more mirrored databases
3) Enable Mirror Service
:
Option?
%SYS>

これで、リストアは完了です。

Namespace vs database

I'm confused about the differences between a namespace and a database.

I understand that a database is a single IRIS.DATA file in a directory in the os hosting IRIS.

What is the difference between a namespace and a database?

Can I write data into a database without specifying a namespace?
If so how do I write to a particlar DB in objectscript?

Does a database have to be in a namespace?
Can a database be in more than one namespace?

Can a namespace have only one 'routine' database and only one 'data' database?

Discovering the Best Curtains for Balcony Dubai Under 300 AED: My Personal Experience

Explore how I found the best curtains for balcony Dubai under 300 AED. Discover affordable picks, trusted suppliers, and the best balcony curtain contractors in Dubai who helped transform my outdoor space.

Introduction: Searching for the Ideal Balcony Curtains in Dubai

When I first moved into my apartment in Dubai, I knew my balcony would be a sanctuary—a place to enjoy breezy evenings and morning coffees. However, the scorching sun and prying eyes from neighboring buildings soon made it clear that I needed curtains. I had a limited budget, not exceeding 300 AED, but I was determined to find the best curtains for balcony Dubai could offer—something stylish, durable, and within my means.

Little did I know, my search would turn into a rewarding journey that led me to discover not only affordable solutions but also some of the best balcony curtain contractors in Dubai and the best balcony curtains company in Dubai.

Initially, I was skeptical. Could I really find high-quality balcony curtains for under 300 AED? Most interior blogs and showrooms showcased luxurious fabrics with equally luxurious price tags. But I reminded myself that in a city like Dubai, where style meets innovation, there had to be budget-friendly options that didn’t compromise on quality or aesthetics.

I began by making a checklist of what I needed:

  • Sun-blocking capability
  • Weather-resistant material
  • Easy-to-install design
  • Aesthetic appeal to match my minimal balcony setup

Exploring Local Markets and Online Options

I started my hunt in traditional markets like Satwa and Dragon Mart. While these places did offer a wide range of options, I found that the curtain materials weren’t always weatherproof—an essential feature given Dubai’s intense summers.

I then turned to local online platforms such as Noon, Amazon UAE, and specialized curtain websites. To my surprise, I found several curtain sets priced well under 300 AED that met my requirements. But I still had concerns about installation and long-term durability.

That’s when I came across a few listings from reputable vendors, some of whom were known to be best balcony curtain contractors in Dubai.

Finding the Right Vendor: Choosing the Best Balcony Curtain Contractors in Dubai

It wasn’t just about finding cheap curtains—it was about finding the right support and service. A friend recommended a local firm renowned as the best balcony curtains company in Dubai. I contacted them, explaining my budget and expectations.

To my relief, they didn’t turn me away due to the low budget. Instead, they offered tailored solutions using affordable yet durable polyester-blend curtains. These were UV-resistant, mold-proof, and perfect for outdoor use.

They even provided free consultation and installation support, something I hadn’t expected for the price.

Installation Day: Transforming My Balcony Space

The day my curtains arrived felt like a mini-milestone. The installation team, representing one of the best balcony curtain contractors in Dubai, arrived promptly. They were professional, friendly, and efficient.

In less than an hour, my balcony was transformed from a sun-soaked concrete slab into a private retreat. The light beige curtains flowed elegantly, blocking the sun while allowing a soft breeze to pass through. For under 300 AED, I had achieved what many premium service providers couldn’t offer—affordability, function, and style.

Key Features That Made the Curtains Stand Out

The product I selected stood out for several reasons:

1. UV-Resistant Fabric

Given Dubai’s climate, UV protection was non-negotiable. The polyester blend used in these curtains was thick enough to block harmful rays while remaining breathable.

2. Water and Mold Resistance

With occasional sandstorms and humidity, having mold-proof curtains added longevity. The material was treated with an anti-microbial coating, which made cleaning easy and hassle-free.

3. Aesthetic Appeal

Despite the low price, the curtains had a luxury feel. The color, stitching, and hanging hardware were modern and sleek—perfect for any balcony setting.

4. Easy Maintenance

They were machine washable, which was a pleasant surprise. A simple cold-water wash restored them to their original brightness after a month of dust exposure.

Trusted Brands and Companies to Consider

During my search, I noted several brands and companies that repeatedly came up in user reviews and community recommendations:

  • Curtain Dubai LLC – Often praised as the best balcony curtains company in Dubai for offering budget-friendly custom solutions.
  • Fixit Design – Known for their prompt services and being among the best balcony curtain contractors in Dubai.
  • Home Style Interiors – A popular option for people looking for a range of designs under tight budgets.

Each of these companies had an online presence, making browsing and ordering incredibly convenient. Many even offered WhatsApp consultations, which sped up the decision-making process.

Tips for Shopping for Balcony Curtains in Dubai Under 300 AED

Based on my experience, here are some useful tips for fellow shoppers:

1. Compare Prices Across Platforms

Often, the same curtain design is listed across various platforms at different price points. Check Noon, Amazon UAE, and local vendors before making a purchase.

2. Ask About Discounts or Packages

The best balcony curtain contractors in Dubai often provide package deals or discounts on installation when you buy in bulk or refer a friend.

3. Focus on Fabric First

Designs and patterns can be adjusted later, but ensure the fabric is suited for outdoor conditions—especially heat, dust, and moisture.

4. Check Customer Reviews

Look for reviews that specifically mention durability, ease of installation, and customer service. These reflect the real user experience more than glossy photos.

Final Thoughts: Achieving Beauty and Comfort on a Budget

This journey taught me that even in a city as upscale as Dubai, it is absolutely possible to balance affordability and style. With just 300 AED, I found curtains that enhanced my home’s functionality and beauty—thanks to the expertise of the best balcony curtain contractors in Dubai and guidance from the best balcony curtains company in Dubai.

My balcony is now a private escape, shielded from the sun and neighbors, where I can unwind without worry. More importantly, I didn’t have to break the bank to achieve this transformation.

Conclusion: You Can Do It Too

If you're facing the same dilemma I was—wanting the best curtains for balcony Dubai on a budget—know that it's completely achievable. Set your expectations, research well, and connect with the right vendors. You’ll be amazed at how small changes can make a big difference.

After all, every corner of your home deserves attention—even the balcony. And with options under 300 AED, you have no excuse not to elevate your space today.
