jpa - Eclipselink caching problem (one database for two systems) -

-

I have two online-systems running both of them using eclipsealic.

The first system is an administration system, where value of other applications is managed. The second system is an online shop where customers can buy articles. Both run on the server and use the same Oracle database.

To provide quick access, value items are cached by Eclipsellic.

If I want to flush the cache to the shop system to get a price in the administration system, to get the value of the new system. What is the best way to solve this problem?

I have a similar problem but it is with user credentials

< Strong> 1) Configure caching in store-side

You can configure eclipse link caching for the duration of the expiry. You can configure it so that the timetololyval or value expires on. For example, you can configure the expiry of prices after 1, 5 or 10 minutes. Not immediately, but very quick and very easy to implement. View catch cat annotations in EclipseLink

2) Contact the admin app to the shop app

This web-service may be worth making It remains on the side which will cancel the cash when it is called. Slightly fragile but depending on your setup, it may be necessary.

3) Use cache sync

EclipseLink has functionality for caching sync. I have never used it but it seems that this may be the best policy for you. You can see the EclipseLink document for more information.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
