Simple database for server.

Hi
I have a curious request but maybe someone could help me. We have a critical server that is having control of all the pumps of the city. So with that server water flows and the citizens are happy!
On that server, there are some service providers that log on it to make maintenance work. The problem is that the employees of that department know when they log in and but
not what they do when they are in.
They want to put a single excel file on the desktop so that every service provider would have to fill (date, time, name of company, user name, what they did on the server etc...). Best practice for servers do not recommend installation of Microsoft Office
and i totally agree with that. Still I have to offer them an alternative. Do you know a simple software that could do something related to excel. That way they will be able to get what they need but at the same time the server will not be able to open xls/
xlsx files.
Thank you for your help.

I guess you could use a text file as a log and vendors could just use built-in notepad.exe to create field delimited log entries like this:
Date/time; Service Provider; Change
Feb 17, 16:35; Vendor ABC; did some stuff
Feb 17, 19:49; Vendor XYZ; changed setting blue from to 123 to 999
But creating a (PowerShell) script on the desktop that vendors double-click, that prompts them for information and then writes that information to the server's (or better yet remote server's)
Event Log seems like a better approach. With the Event log approach, vendors can't tamper with previous log entries or entries from other vendors.
If this is really a critical system that controls the water supply for a city, you need much tighter change control and security then this; the honor system doesn't cut it. You didn't really
need to tell us about the fact that this system controlled the critical infrastructure of your city; there's no need to make the bad guys job any easier finding targets.

Using simple database for an application

Hello,
Here is my need :
I will develop an application based on two or three gui-clients java based and a database (all on linux based system).
What choice for the database ?
First I had a look on javadb, I was interested by the easy to use aspect and the embedded mode. But I have two applications that have to access the database in the same time and javadb has to be used in a "framework server" to accept multi-user (and this seems to be too complex for my use).
The database will be very simple (4 or 5 tables and 1000 lines in the biggest table) and has to be shared between 2 ou 3 apps.
I had a look on SQLite but the use of JNI obstructs me.
Do you have other ideas to answer to my need ? Is there a way to share the file system where the data files of javadb is (by NFS for example) ? And start two derby service using the same files in two different JVM ?
Thanks for your help and advices.

I have used HSQLDB for awhile. I have found it to be very useful, though I've mostly used it for simple, read-only databases. Definitely what I would recommend for your situation.

Guidelines to copying a database for server change

Hi,
We have a 12 GB database of version 8.1.7.4 on aix 5.1. This has to be copied to a server of aix 5.3 and all are local disks.
Is the following procedure fine for doing the copy and startup:
1) Maintain the os file structure on the new server.
2) Install database 8.1.7.4 on the new server.
3) Taking an online backup of the current database and copying to new server.
4) Shutting down the production database
5) Copying all the online redo log files to the new server and doing cancel based recovery until no change is requested.
6) Copying the tnsnames.ora, sqlnet.ora and listener.ora files and starting the listener.
7) Starting the database.
Is it necessary to upgrade the db before copying?

1) Maintain the os file structure on the new server.
2) Install database 8.1.7.4 on the new server.
3) Taking an online backup of the current database and copying to new server.You can take the backup of all the files after shutting down which will make life easier but still it should be OK
4) Shutting down the production database
5) Copying all the online redo log files to the new server and >doing .cancel based recovery until no change is requested.
6) Copying the tnsnames.ora, sqlnet.ora and listener.ora files and starting the listener.
7) Starting the database.Make an entry in the /etc/oratab to startup the database automatically upon reboot and also you should an entry in file i couldnt remeber now
No need to upgrade anything just copy will do everything

Looking for a simple database app.

I have an Excel sheet that i use to store simple database data. Like a flat file database with only 4 columns, no relations, no calculations, just data storage.
I don't want to download and install over a 100Mb of OpenOffice or NeoOffice just to be able to see my Excel sheet so i was thinking at converting it to a simple cardfiler-like database.
Guess what? There are no simple databases for the Mac! There is OpenOffice and NeoOffice and there is FileMaker. But no simple, small, configurable card-filer. I checked VersionTracker, IUseThis, but i cannot find anything.
That makes me think that it already needs to be available on the standard installed apps (please say that i'm right) and i just don't see it.
Any suggestions? Any help? Am i really missing the point here?
Thanks all!
Ton.

Haven't looked at Wallet. Looked at iData, but that is payware now. I'm trying now woth OmniOutliner which seems to look ok.

How can i build the server?
How can i make the connection with the database?
Are there tutorials or examples?
Please help.
Thanks in advance.

I'd say Hypersonic SQL (HSQLDB) is your simplest bet; easy to setup and no software installation required because it is a pure java database. All you need to know is on their website:

ISSUE Sharepoint 2013 databases for reporting services on the second server SQL 2012

Hello,
I have server A: Operating system windows 2012 standard, SQL server 2012 standard
instance: Sharepoint contains data for sharepint
instance: Reporting should be contain databases for reporting
Server B:
Windows server 2012 standard contains installation Sharepoint 2013
Sharepoint works (without reporting services), it is OK - databases are located on server A:
My issue is:
When I have installed reporting services on server B, I have already installed SQL server 2012 on server B, it works.
I am able to create report in report builder adn place it in to sharepoint.
But I would like to use only one full SQL machine on server A:
When I reconfigure repoting settings on server A in central administration - manage service aplications,
On the SQL server A in instance reporting , there is automatically created databases. It is no problem.
But the first difference is, when I want to manage service aplication for reporting in
Provision Subscriptions and Alerts, there is information
SQL Server Agent state cannot be determined
When I want to create report in report builder, I have issue:
server A-7380mw016\reporting it means server A with full SQL server:
The Test of connection was successful
Then I have clicked test connection
I have recieved this screen with fail: Logon faild for user NT Authority\anonymous logon
My account belongs to SQL admin on server A (A-7380mw016\reporting) I do not know it is not possible to create report, when it is possible to test connection in the first step and in the second step, there is problem...
Please, can somebody help me?

Hi,
Since you are getting an Anonymous Logon error, it appears there may be a problem passing your credentials to the SQL Server Agent Service. This would indicate a Kerberos issue. See this thread for details:
http://social.technet.microsoft.com/Forums/sharepoint/en-US/46b7c773-6a77-435d-b471-cb9a6ec41c43/has-anyone-else-upgraded-reporting-services-to-denali-2012

http://technet.microsoft.com/en-us/video/Video/hh858469
Tips from the video:
We are connecting to Reporting services using Kerberos when using Reporting Services in SharePoint integrated mode
For the account using reporting services, we just need a dummy SPN. We go to Attribute editor tab in AD for RS account. And then we will be enabled with Delegation tab.
In Delegation tab. I we are using claims to windows token, we need to use "Trust this user for delegation to specified services only"
There you have 2 options: "Use Kerberos only": It means I only want to delegate in the situation where the service that is doing the delegation actually has the Kerberos ticket to start with
"Use any authentication protocol" When we need protocol transition (like from NTLM to claims for intra farm communication)
We need to delegate this to SQL server.

Global query block is causing a DNS server to fail a query with error code Name Error exists in the DNS database for WPAD

Global query block is causing a DNS server to fail a query with error code Name Error exists in the DNS database for WPAD on a Windows 2008 server.

The global query block list is a feature that prevents attacks on your network by blocking DNS queries for specific host names. This feature has caused the DNS server to fail a query with error code NAME ERROR for wpad.contoso.com. even though data
for this DNS name exisits in the DNS database. Other queries in all locally authoritative zones for other names that begin with labels in the block list will also fail, but no event will be logged when further queries are blocked until the DNS server
service on this computer is restarted.

SQL ENTERPRISE: The edition of Reporting Services that you are using requires that you use local SQL Server relational databases for report data sources and the report server database

The error below makes absolutely no sense! I'm using Enterprise Core...yet I'm being told I can't use remote data sources:
w3wp!library!8!03/05/2015-19:08:48:: i INFO: Catalog SQL Server Edition = EnterpriseCore
w3wp!library!8!03/05/2015-19:08:48:: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.OperationNotSupportedException: , Microsoft.ReportingServices.Diagnostics.Utilities.OperationNotSupportedException: The feature: "The edition of Reporting
Services that you are using requires that you use local SQL Server relational databases for report data sources and the report server database." is not supported in this edition of Reporting Services.;
Really? This totally contradicts the documentation found here:
https://msdn.microsoft.com/en-us/library/ms157285(v=sql.110).aspx
That article says remote connections are completely supported.
ARGH! Why does this have to be so difficult to setup?!?

Hi jeffoliver1000,
According to your description, you are using Enterprise Core edition and you are prompted that you can’t use remote data sources.
In your scenario, we neither ignore your point nor be doubt with what you say. But actually we have met the case before that even though the SQL Server engine is Enterprise but the reporting services is still standard. So I would recommend you to find the
actual edition of reporting services you are using. You can find Reporting Services starting SKU in the Reporting Service logs ( default location: C:\Program Files\Microsoft SQL Server\<instance name>\Reporting Services\LogFiles). For more information,
please refer to the similar thread below:

By the way, have you installed the other SQL Server edition before?

Oracle Database Mobile Server 11 sync

Hi,
I have two simple tables in the back-end oracle database in order to create a meeting-room android application with and embebbed SQLite database on the client devices. I have written all the functionality to register, authenticate, create a new appointent, show it, and delete it and it works fine on my smartphone, but I did all these steps against the local sqlite db.
Now I would like to share the reserves info with all the clients by synchronization using Oracle Database Mobile Server 11.
Tables:
Employees(ID, username, password, firstname, lastname, phone, email)
Reserves(ID, subject, firstname, lastname, start_date, end_date, meeting_room, alarm)
I have configured all the publications required (app , item, users, grants...) with the Workbench tool, like i have read from the official documentation and i added the lines to invoke the sync functionality. My problem is that when i launch the first sync the sqlite database in created on the device but the few records on the back-end are not replicated in the sqlite db. ¿is this process automatic or have I to write some code to catch this info?
Another problem is that the records of the sqlite database is neither replicated to the back-end database. I have to say that th sync process ends succesfully but I can see nothing on the in-queue and out-queue queues in the mobile manager console. So, what´s about this incomind and outcoming data? Th only thing i can see is a set of dirty records, these records are records on the back-end db, but I dont know what means...
Could you help me please?
Thank you very much.

Hi
Data Subsetting is to restrict the data each Client sees based on values you specify i.e.
If you only wanted a Client to see data for a specific Dept you could specify the following in the Publication Item
Select * from emp where DEPTNO = :DEPTNO
You can define what DEPTNO should be for each Client in the Mobile Server
So in your case if you want ALL Client to see ALL records for a Publication Item then you should not specify any Data Subsetting i.e.
Select * from emp - This would retrieve all rows
There is no specific need to use Sequences in your Application unless you want to. Obviously you must make sure that any new records created on the Client will not conflict with a record created on a different Client otherwise conflicts will occur after the data is synchronized with the server
With regards to you actual issue can you confirm the following ( NO NOT CHANGE ANY VALUES )
1. Check the table mobileadmin.applications in the Repository DB and confirm there is a row there for your Application and that the 'Publication' column contains the correct Publication you created in MDW.
2. Check the Table C$ALL_CLIENT_ITEMS, this should contain one row for each Publication Item you created in MDW i.e.
Select PUBLICATION_ITEM, DIRTY, CRR From C$ALL_CLIENT_ITEMS Where CLIENTID = '<Your Client Name>';
regards

A very simple database system with JSON

If we need to store some data in a database, but without the need of advanced SQL features, can we use this scheme (written here in Javascript / node.js) :
// the DB will be in RAM !
var myDb = {};
// read DB from disk if file exists
try { myDb = JSON.parse(fs.readFileSync(DBFILENAME)); } catch(e) { }
// serialize to disk every minute or when process terminates
function serialize() { fs.writeFile('./myDb.json', JSON.stringify(myDb)); }
setInterval(serialize, 60 * 1000);
process.on('SIGTERM', serialize); process.on('SIGINT', serialize);
myDb['record1'] = 'foo';
myDb['record2'] = 'bar';
See
the longer version here as a gist (8 lines of code).
1) Does this DB practice have a name? Is it really so bad? Is it possible to use such a
10-lines-of-code DB system, even in production of websites that have a < 1 GB database ?
2) Scalability: until which size would this system work without performance problems?
i.e. would it work until 2GB of data on a a normal Linux server with 4GB RAM? Or would there be real performance problems?
Note: a minute seems enough to write a 2GB data to disk... Of course I admit it is 100% non-optimized, we could add
diff feature between n-1th and nth writing to disk...
3) Search: can I use ready-to-use tools to do some search in such a "simple" database? Lucene, ElasticSearch, Sphinx, etc. something else?

Nothing is wrong with this for development. If it has a name, I suppose it would be a mock database. It is not uncommon to create a mock database that can emulate very basic functionality. You have the added advantage that you start from a scratch
database each and everytime, thus you know that your program would work also for a potential empty nosql database for the same reason.
However this is not a reasonable permanent solution by any means.
Most programmers, due to the small overhead, will simply go ahead and make it work with a nosql database. It may take slightly longer, you are also programming directly to work in production and not being forced to adapt your program and test it beforehand.
Scalability is a non-issue because you're always working in development. If you crash your own computer, it is not that big of a deal. The limit of such a database would be only that of your RAM (or the RAM of the computer running the server), however I
think you'd find that you'll find that the program gets very slow before you even reach the point when your program will crash.
Perhaps you could adapt some searching mechanism for the mock database, but if you're going to go through the trouble, just go ahead and use a proper nosql database. If you literally lose more than 1 hour working on this mock database, then you've wasted
time.

If DW 2014.1 cc does not support database, binding, server behavior, and PHP/MySQL require it, but using Adobe Extensions Mngr IS NOT recommended, then WHAT TOOLS do we use to develop a database with DW?

I'm using windows DW 2014.1 cc. I'm following lynda.com tutorials to build a website database with PHP and MySQL. I learned I have to download Adobe Extension Mngr to active DATABASE, BINDING, SERVER BEHAVIOR panels, which I've done. BUT NOW I'VE BEEN ADVISED NOT TO USE THESE TOOLS for new development. If this is the truly the case, then WHAT TOOLS DO I USE to develop a website that has a database?

then WHAT TOOLS DO I USE to develop a website that has a database?
Besides the tools you would already need for a system using server behaviors (web server, PHP, MySQL, phpMyAdmin) the only extra tool you need is your own brain.
A lot of people are disappointed by the lack of database tools in DW now, but really it's much better this way. You can never achieve better than a rinky-dink dynamic website using server behaviors. The code Dreamweaver dynamic behaviors create is really terrible. (I'm not insulting the fine folks who wrote the feature. It's just a consequence of automated code.) You can write better, simpler, more maintainable code yourself, and over time you will improve. With server behaviors you cannot improve. you get stuck in database kindergarten.

I want to use Berkely database for my Dissertation

Hello everyone,
I am having some doubts regarding Berkely database. Actually, I am using this database for my project. The scenario of the project is, I have developed some business rules depending on the concept of Ripple Down Rules and represented the rules using Conceptual graphs. Now I want to store fire these business rules in to the Berkely database, so that my application can use these business rules from the Berkeley database.
This is the context of my project. But, I am very new to this Berkely database. I have downloaded the Berkely database from the Oracle website and also installed it. The OS is am using is Windows XP SP2. Can anyone explain me how to store Conceptual graphs in a Berkely database.
I am really a beginner to Berkely database. i don't even know what to do after installing the Berkely database. Please advise me about this.
I would be very thankful to you.
Cheers,
Phani.

Hi Phani,
The simple answer is however you want. Berkeley DB doesn't put any constraints on how you store data in it. Its main purpose is to provide an efficient and scalable key/value storage and retrieval system, upon which you can build your own data storage system.
More specifically, if you're representing graph data, the simplest way to do so is with the "edge list" paradigm. You could, for example, set up a pair of databases, one to store all your graph nodes (with associated metadata) and one for directed edges. I'm not sure what particular c structures you'll want to use for these, but I'd suggest using record numbers on both the nodes and the edges DBs, unless all your nodes have unique and meaningful names. I'd also allow duplicate records on your edges DB, and have a very simple record structure in it that simply maps from a source node id to a destination node it (the duplicates allow multiple edges from a given node.)
If you have more specific constraints on your graph and algorithms you'd like to run on it, there are potentially more schemes you could use, such as the nested set representation for trees, and so on.
Hope this helps,
Daniel

Duplicate target database for standby failing with below error

Hello All, Need your assistance
We are creating a physical standby database (standalone) from 2 node RAC database, OS =RHEL5 and DB =11gR2

How can i use a database for practice in DOS

i have some problems in the sqlplus.
My OS is windows2000 server,when i intalled the Oracle 8i
i type a command 'cmd' go to DOS.and type "sqlplus username/password@database"
but always the system say that my database name can't be deal with.
and i want to get a sample database for training SQL statements.How can i get it.
is Oracle 8i have the sample database.

It sounds like your database hasn't been started yet so do this:
Try typing svrmgrl at the c:> -- if it doesn't work you might either have to go to the proper directory or type sqlplus to get an sql:> prompt (I don't remember it's been a while) but the rest I am pretty sure about---
When you get the svrmgr prompt:
use (i think) "connect internal"
and "oracle or Oracle" as password
once you do this
it should say connected
then use: svrmgr:>shutdown -- shutsdown DB
then use: svrmgr:>startup -- starts DB
hopefully then you can access your database through SQL Plus

How to use the mirrored and log shipped secondary database for update or insert operations

Hi,
I am doing a DR Test where I need to test the mirrored and log shipped secondary database but without stopping the mirroring or log shipping procedures. Is there a way to get the data out of mirrored and log shipped database to another database for update
or insert operations?
Database snapshot can be used only for mirrored database but updates cannot be done. Also the secondary database of log shipping cannot used for database snapshot. Any ideas of how this can be implemented?
Thanks,
Preetha

Hmm in this case I think you need Merge Replication otherwise it breaks down the purpose of DR...again in that case..
