  • Mysql out of disk space

    - by Paddy
    I have just finished developing a rails app which has a mysql db as a backend. The app is meant for high traffic and will store lots of information. I am planning to set up my own web server and host the site from it. If in future my disk space runs out i would want to expand by adding more space. But say if my mysql database is housed in my /disk0s1 and by adding a new drive i have more partitions (and hence more disk space), how then would i extend my database to store information on those partitions too, and at the same time prevent any information from being written on the original partition. Should i go for multiple databases? if so how? If i went for a hosting solution i wouldn't be bothering about this as i would just have to worry about making payments for the extra space :) I always wondered how space is added on-the-go by these webhosts. Is there any specific mysql configuration that i have to make?

  • Memory management / ownership question?

    - by fuzzygoat
    Do I have this right ... // Reactor.h @property(nonatomic, retain) NSMutableArray *reactorCore; // Reactor.m [self setReactorCore:[NSKeyedUnarchiver unarchiveObjectWithFile:[self dataFilePath]]]; ... -(void)dealloc { [reactorCore release]; [super dealloc]; } I am pretty sure I am doing this right (but just wanted to check). By my way of thinking NSKeyedUnarchiver returns an object it owns, I am then taking ownership via the @property, later I release reactorCore and all is good?

  • Can I use imp/exp tools to migrate database from Oracle 9 to Oracle 10

    - by Karol Kolenda
    I'm subcontractor and my client wants to upgrade Oracle database from 9 to 10. Other vendor is going to perform the upgrade process, and I was asked to create whatever backup I need before the upgrade, and then recreate the environment in Oracle 10. All my data is stored in a separate database in a single schema. No fancy relations, scripts or anything like this (actual app supports different dbs: Oracle, SQL Server, Postgres so we want to avoid any DB-specific code). I was hoping to use imp/exp but I'm not sure if imp/exp are backward compatible (exp from O9 and imp to O10)? If there is a better/recommended way of dealing with similar situation, I'll be grateful for any advice.

  • Subscription Management with Merchant Account via API

    - by Josh
    I'm researching gateways/vendors that provide the ability to create subscription based transitions for merchant accounts. In other words, I want to allow customers to signup for a subscription for a website service that charges once a month. Authorize.Net has an ARB (Automated Recurring Billing) Module. The cost is cheap, $10 a month for the service, with unlimited subscriptions, and they have an API that allows XML or SOAP access to create, update and cancel. The LARGE negative of the service is that it doesn't have elegant way to obtain the current status of a subscription. They can send a daily email with an attached CSV file, or someone can login into the site and review statuses – neither is an enterprise solution. The parent company "CyberSource" has a "Recurring Billing Service" which implies a more robust solution, including API access to subscription information. I’m currently waiting for a sales call back on costs related to the service. I also looked at PayPal's Recurring Billing Service, but that appears to require that users are redirected to the PayPal site to signup for the subscription -- again, not an an elegant solution. Does anyone know of any other vendors/gateways that offer subscription service, that meet the following criteria: Vendor/Gateway must host the credit card number and be PCI compliant Have an API that accessible via a Web Service, Post over HTTPS or SOAP Have an API that allows querying the status of subscriptions and/or the ability to query for activity since a certain date. Thanks in advance for your suggestions.

  • Kohana v3 ACL A2 with database support

    - by Asif
    Hi, I am using Kohana V 3.0.3. I was looking for ACL library and found from http://dev.kohanaphp.com/projects A2 Kohana's ACL module. Apparently it's found that, it manages Roles,Resources and Rules using config file and authenticate object basis. I want it to be dynamic, like Resources and Rules should be loaded from database dynamically if valid user logs in. Auth part is done now looking for ACL part. Is it possible to use same A2 module with database or need to rewrite own logic?

    - by dkackman
    I have spent my career on the software development side of things and in the latter part have become more and more involved in the realm of Software Configuration Management. Now I am moving into an IT group and need to ramp up on CM practices from that standpoint. Are there any good references (books, websites, blogs whatever) out there comparing Software CM practices to IT CM practices? Basically I'm in learning mode and am trying compare things I already know from the software development side to things on the IT side.

I was told that for biztalk, logshipping is not like standard logshipping.

  • MYSQL backup and restore

    - by Codezy
    I am having trouble getting mysql backups to run properly when their are views in the database. I think this might have something to do with needing a placeholder object for it. In any event I run this command: mysqldump -u myuser -pmypassword mydatabase | mysql -u myuser -pmypassword -C mydatabase_Beta The user has full privileges and I get this: View mydatabase_beta.yadayada references invalid tables or columns or functions or definer/invoker or view lack rights to use them. How can I back it up so that it restores all of my database properly? In the example I am restoring it to a different name but I do need to be able to restore a working copy. I think it is probably an additional mysqldump parameter or maybe hot copy would work better. Thoughts?

  • Overhead of Perfmon -> direct to SQL Database

    - by StuartC
    HI All, First up, I'm a total newb at Performance Monitoring. I'm looking to set up central performance monitoring of some boxes. 2K3 TS ( Monitor General OS Perf & Session Specific Counters ) 2K8 R2 ( XenApp 6 = Monitor General OS Perf & Session Specific Counters ) File Server ( Standard File I/O ) My ultimate aim is to get as many counters/information, without impacting the clients session experience at all. Including counters specific to their sessions. I was thinking it logging directly to a SQL on another server, instead of a two part process of blg file then relog to sql. Would that work ok? Does anyone know the overhead of going straight to SQL from the client? I've searched around a bit, but havent found so much information it can be overwhelming. thanks

  • ASP.NET MVC 2 Dynamic QueryString Management

    - by vikas anand
    Hello All, I am very new to ASP.NET MVC and currently, I am involved in developing a new application in ASP.NET MVC 2. I am having problem in managing a long querystring parameters that comes from dBase. For example, in any non-mvc app the following URL works well: http ://example.com/test.aspx?first_name=fname&last_name=lname&email_id=email&address1=add1&address2=add2&city=city&state=state&zip_code=zip and so on. The QueryString parameter can be determined on the fly (i.e. at run-time). Now for dynamic QueryString how routing will be done? Also for a simple URL, the URL will be as follows (in ASP.NET MVC): http ://example.com/test/id/category But for above mentioned dynamic & long QueryString how the URL will look like? Will all the QueryString parameters be separated through slash (/)? Thanks in advance for your help. Best Regards, Vikas Anand

  • Associating multiple data with a single entry in Open Office Base

    - by idyllhands
    I'm trying to build a database that I can use to track prices of groceries on certain dates. My problem is that I cannot figure out how to have a single entry associate with multiple data. For example, carrots. The index would be carrots. Then, a few categorizing fields (ie, Produce|Vegetable) Then, I can enter a price, date that the price was valid, store that was selling for said price, etc. And the next time I buy carrots, I can just add a new set of pricing data that would be associated with the original carrots entry. I know very little about database building, so if anyone has something I could just modify, I would greatly appreciate it. Alternatively, a step by step tutorial would be great.

  • Getting Active Session counts with JMX (Java Management Extensions) API

    - by bLee
    I'm trying to use JMX API to get active session counts for a web application. Is it possible to use JMX API to get this kind of information? If yes, how reliable would it be? Any example code on how to get this done? I've been reading JMX tutorial and documentation, but they are giving me the overview of what the technology is. I just can't pinpoint to what I need, yet.

  • How to make QT support HTML 5 database?

    - by Mickey Shine
    I am using Qt 4.7.1 and embedded a webview in my app. But I got the following error when trying to visit http://webkit.org/demos/sticky-notes/ to test the HTML 5 database feature Failed to open the database on disk. This is probably because the version was bad or there is not enough space left in this domain's quota I compiled my static Qt library with the following command: configure --prefix=/usr/local/qt-static-release-db --accessibility --multimedia --audio-backend --svg --webkit --javascript-jit --script --scripttools --declarative --release -nomake examples -nomake demos --static --openssl -I /usr/local/ssl/include -L /usr/local/ssl/lib -confirm-license -sql-qsqlite -sql-qmysql -sql-qodbc

  • Using hibernate criteria, is there a way to escape special characters?

    - by Kevin Crowell
    For this question, we want to avoid having to write a special query since the query would have to be different across multiple databases. Using only hibernate criteria, we want to be able to escape special characters. This situation is the reason for needing the ability to escape special characters: Assume that we have table 'foo' in the database. Table 'foo' contains only 1 field, called 'name'. The 'name' field can contain characters that may be considered special in a database. Two examples of such a name are 'name_1' and 'name%1'. Both the '_' and '%' are special characters, at least in Oracle. If a user wants to search for one of these examples after they are entered in the database, problems may occur. criterion = Restrictions.ilike("name", searchValue, MatchMode.ANYWHERE); return findByCriteria(null, criterion); In this code, 'searchValue' is the value that the user has given the application to use for its search. If the user wants to search for '%', the user is going to be returned with every 'foo' entry in the database. This is because the '%' character represents the "any number of characters" wildcard for string matching and the SQL code that hibernate produces will look like: select * from foo where name like '%' Is there a way to tell hibernate to escape certain characters, or to create a workaround that is not database type sepecific?

  • SQL Server database backup: Network Service file access

    - by Keith Maurino
    When trying to run the following database backup command from my code I get an "Operating system error 5(Access is denied.)" error. This is because the log on account for the SQL Server Windows Service is 'Network Service' and that does not have access to right to this folder. BACKUP DATABASE [AE3DB] TO DISK = 'c:\AE3\backup\AE3DB.bak' My question is, from my code how would I go about figuring out where on the C drive 'Network Service' is allowed to right the backup to? NOTE: This is a distributed application so I cannot easily change the log on for the SQL Server Windows Service to the 'Local System' account that would be able to right to that folder.

  • Connecting to RDS database from EC2 instance using bind9 CNAME alias

    - by mptre
    I'm trying to get internal DNS up and running on a EC2 instance. The main goal is to be able to define CNAME aliases for other AWS services. For example: Instead of using the RDS endpoint, which might change over time, an alias mysql.company.int can be used instead. I'm using bind9 and here's my config files: /etc/bind/named.conf.local zone "company.int" { type master; file "/etc/bind/db.company.int"; }; /etc/bind/db.company.int ; $TTL 3600 @ IN SOA company.int. company.localhost. ( 20120617 ; Serial 604800 ; Refresh 86400 ; Retry 2419200 ; Expire 604800 ) ; Negative Cache TTL ; @ IN NS company.int. @ IN A 127.0.0.1 @ IN AAAA ::1 ; CNAME mysql IN CNAME xxxx.eu-west-1.rds.amazonaws.com. The dig command ensures me my alias is working as excepted: $ dig mysql.company.int ... ;; ANSWER SECTION: mysql.company.int. 3600 IN CNAME xxxx.eu-west-1.rds.amazonaws.com. xxxx.eu-west-1.rds.amazonaws.com. 60 IN CNAME ec2-yyy-yy-yy-yyy.eu-west-1.compute.amazonaws.com. ec2-yyy-yy-yy-yyy.eu-west-1.compute.amazonaws.com. 589575 IN A zzz.zz.zz.zzz ... As far as I can understand a reverse zone isn't needed for a simple CNAME alias. However when I try to connect to MySQL using my newly created alias the operation is giving me a timeout. $ mysql -uuser -ppassword -hmysql.company.int ERROR 2003 (HY000): Can't connect to MySQL server on 'mysql.company.int' (110) Any ideas? Thanks in advantage!

  • SQL 2008 SMO Database Status property memory leak.

    - by AKoran
    It appears there is a memory leak in the Status property of the SMO Database class. Using the code below with SQL 2005 SMO libraries works fine, but as soon as you use SQL 2008, the memory leak appears.... Any other good way of getting the database staus in SQL 2008? A quick example that magnifies the problem: private void button1_Click(object sender, RoutedEventArgs e) { for (int x = 0; x < 100; x++) { CheckStatus(); } } private void CheckStatus() { Server server = new Server("YourServer"); DatabaseCollection dbc = server.Databases; if (dbc.Contains("YourDatabase")) { DatabaseStatus dbStatus = dbc["YourDatabase"].Status; } }

  • Repairing inconsistent pages in database

    - by Raj
    We have a SQL 2000 DB. The server crashed due to Raid array failure. Now when we run DBCC CHECKDB, we get an error that there are 27 consistency errors in 9 pages. When we run DBCC PAGE on these pages, we get this: Msg 8939, Level 16, State 106, Line 1 Table error: Object ID 1397580017, index ID 2, page (1:8404521). Test (m_freeCnt == freeCnt) failed. Values are 2 and 19. Msg 8939, Level 16, State 108, Line 1 Table error: Object ID 1397580017, index ID 2, page (1:8404521). Test (emptySlotCnt == 0) failed. Values are 1 and 0. Since the indicated index is non-clustered and is created by a unique constarint that includes 2 columns, we tried dropping and recreating the index. This resulted in the following error: CREATE UNIQUE INDEX terminated because a duplicate key was found for index ID 2. Most significant primary key is '3280'. The statement has been terminated. However running Select var_id,result_on from tests group by var_id,result_on having count(*)>1 returns 0 rows. Here is what we are planning to do: Restore a pre-server crash copy of the DB and run DBCC CHECKDB If that returns clean, then restore again with no recovery Apply all subequent TLOG backups Stop production app, take a tail log backup and apply that too Drop prod DB and rename the freshly restored DB to make it prod Start prod app Could someone please punch holes in this approach? Maybe, suggest a different approach? What we need is minimum downtime. SQL 2000 DB Size 94 GB The table that has corrupt pages has 460 Million+ rows of data Thanks for the help. Raj

  • Where is my SQLite database?

    - by Brian Ramsay
    I have installed SQLite version 3 into a non-standard location on my dreamhost user account. I compiled it and installed it just fine, and it works with $db=new SQLiteDatabase("db.foont"); I can create tables and insert and read data with the SQLiteDatabase object just fine. However, I want to use PDO. My problem is that PDO requires an absolute path to the database specified in the connection. e.g., 'sqlite:/path/to/db.sq3' a) this is dumb - if the other object can figure out where the db is without an absolute path why can't PDO's sqlite driver - but that's not my question. b) where the heck is my database being stored? I can't find it anywhere in my user filesystem, and I'm pretty sure I don't have access to anything else.
