I have my Crystal Reports server configured against an Oracle data source, but now I need to switch it to be configured against a SQL Server data source, on a different server. This server has no way to communicate with the original server to use the import tool.
I was looking into how to import the data myself. Looking at the tables, I see that it stores binary fields in the database. Are the reports stored as binary data inside the data source, or does each RPT file has a copy somewhere on the disk? If it is on the disk where? If it's inside the data source binary field, does importing the data to a new server will still work?
The CCM (Central Configuration Manager) – not to be confused with the CMS – has the ability to migrate your database repository from one database to another, even if the database vendor differs (i.e. Oracle vs. Microsoft).
Have a look at the administrator guide, the procedure is described in chapter 11, Managing Central Management Server (CMS) Databases, section 4 Copying data from one CMS system database to another.
A small excerpt:
You can use the Central Configuration Manager (CCM) or cmsdbsetup.sh
to copy system data from one database server into another database
server. For example, if you want to replace the database with another
database because you are upgrading the database or are moving from one
database type to another, you can copy the contents of the existing
database into the new database before decommissioning the existing
database.
Regarding the reports themselves, they are not stored in the database, but in the file repository. However, you need to view the database and file repository as one: the first contains the metadata while the latter contains the actual files. However, they can not function separately.
In other words, you cannot just copy the RPT files from the file repository to another server and expect them to work, as the information that is contained in the metadata (such as authorisations) will be missing. On the other hand, if you just copy the database repository but omit the file repository, you'll end up with all the information regarding your reports, but you won't be able to open or run them.

I am trying to follow quickstart to setup SQL Server (not LocalDb version of SQLServer that comes with Visual Studio) as my data store. Looks like that two databases will be needed - one for configuration and the other for operation. But my problem is that I couldn't figure out what db names I should use. I created two databases using names I came up with and ran the scripts I downloaded from quickstart to create all the tables. Now, when I try to make connection, I think I will need to specify db names in my connection string, don't I? What should I use to replace the original connection string provide by quickstart - "Data Source=(LocalDb)\MSSQLLocalDB;database=IdentityServer4.Quickstart.EntityFramework-4.0.0;trusted_connection=yes;" ?
You can have one database for both. But in general I would keep the configuration part in memory if the number of clients is small. Why spend hours keeping the config in a database for just a few clients and resources?
Better to just keep the users and persisted grants in a database.
we are using 2018.3 version of Tableau Server. The server stats like user login, and other stats are getting logged into PostgreSQL DB. and the same being cleared regularly after 1 week.
Is there any API available in Tableau to connect the DB and take backup of data somewhere like HDFS or any place in Linux server.
Kindly let me know if there are any other way other than API as well.
Thanks.
You can enable access to the underlying PostgreSQL repository database with the tsm command. Here is a link to the documentation for your (older) version of Tableau
https://help.tableau.com/v2018.3/server/en-us/cli_data-access.htm#repository-access-enable
It would be good security practice to limit access to only the machines (whitelisted) that need it, create or use an existing read-only account to access the repository, and ideally to disable access when your admin programs are complete (i.e.. enable access, do your query, disable access)
This way you can have any SQL client code you wish query the repository, create a mirror, create reports, run auditing procedures - whatever you like.
Personally, before writing significant custom code, I’d first see if the info you want is already available another way, in one of the built in admin views, via the REST API, or using the public domain LogShark or TabMon systems or with the Addon (for more recent versions of Tableau) the Server Management Add-on, or possibly the new Data Catalog.
I know at least one server admin who somehow clones the whole Postgres repository database periodically so he can analyze stats offline. Not sure what approach he uses to clone. So you have several options.
I have done a lot of research on the file types of tableau but I would still like to know more about some file extensions
What is the relation between twbx and tdsx?
Is twbx file : twb + tde file OR twb+tde+tds file ?
What would be the main difference between tds and tdsx file ?
How to use a tps(preferences) file in tableau workbook?
can all the file extensions be used on server or only some ?
twbx contains the workbook including a copy of all the data that you connected your workbook to, while a tdsx contains connection information to remote data sources (Server IPs, tables, etc) as well as any local data that somebody else wouldn't have access to otherwise (eg. an Excel file on your computer). No dashboards are involved. https://onlinehelp.tableau.com/current/pro/desktop/en-us/export_connection.html
A twbx is a twb with a tde file if you want. Remote and local data is stored within your workbook so that other people can access it https://onlinehelp.tableau.com/current/pro/desktop/en-us/save_savework_packagedworkbooks.html
a tds only includes references to data sources but no actual data, so if you connect to a local excel file and it is not accessible via a network, a colleague of yours won't be able to use this file to get the data. A tdsx includes these datasets so you can share it. https://onlinehelp.tableau.com/current/pro/desktop/en-us/export_connection.html
A tps contains custom colour palettes, how you can use it can be found here: https://onlinehelp.tableau.com/current/pro/desktop/en-us/formatting_create_custom_colors.html
Generally all files that you can connect to with Tableau Desktop can be accessed via the server (assuming that the server can access them, ie. the files or sources are on the network). You might however be required to install additional drivers on the server to access for example SAP BW. These drivers are not contained in the default installation.
So I've started a SQL Server database project inside VS 2012. I have done this for other databases already but not related to Service Broker.
For testing I had already created db, queues, etc through a T-SQL script including Message Types which was in an XML format. i.e.
[//blah.com/Items/RequestItem]
When I try to do something like this in the DB Project it's not allowing me too due to special chars.
Anyone done this? Gotten around it?
Is there a way to simply put my already created T-SQL file in the database project and have it use it?
See my comment above. I was able to import the script by Right clicking on the database Project.
I've wrote the code that creates full backups of my ESENT database, using JetBeginExternalBackup API.
Following the MSDN guidelines, I backed up every file returned by JetGetAttachInfo and JetGetLogInfo.
I've made the backup, erased old database, and copied the backup data to the database folder.
The DB engine was unable to start, the JetInit error code is "JET_errMissingLogFile".
I've checked the backup, it only contains the database file, and "<inst>XXXXX.log" log files. It lacks the current log file (I'm using circular logging, BTW).
Is there any way to restore such backup?
I don't want to use JetExternalRestore API because it's too complex: I don't need to restore to another location, I don't understand why there're 3 input folders not 2, and I don't know the values to supply in genLow and genHigh arguments.
I do need external backups: the ESENT database is used by ASP.NET on a remote server, and I'm backing it up over the Internet.
Or, maybe there's a way to retrieve the name of the current log file, and I should just add it to the backup?
Thanks in advance!
P.S. I've got no permissions to span processes on my web server, so using eseutil.exe is not an option.
Unpack all backed up files to a single folder.
Take the name of your main database file. Replace extension to .pat. Create zero-length file with that name, e.g. database.pat.
After this simple step, call JetRestoreInstance API, it will restore the backup from that folder.
