How to dynamically retrieve the host name of the server APEX?
HelloI have request Express installed 3.1.0.00.32 on 2 servers in a configuration of dataguard, which means I can failover from one server to the other.
The problem I encounter is the URL. I wrote a beautiful PL/SQ/procedure to send mail, in the body of the mail it is a URL that points to a hard-coded host name (teleg1:7777)
BEGIN
....
l_url := 'http://teleg1:7777/pls/apex/f?p=109:29:::NO::P29_ID:'||C1.ID ;
....
It can occur I the digital switchover to the other server which name would be teleg2, but then the url change because the host name is "teleg2:7777".It should be like this:
l_url := 'http://teleg2:7777/pls/apex/f?p=109:29:::NO::P29_ID:'||C1.ID ;
Is there a way to retrieve the host name of a global variable of APEX, something like G_HOSTNAME? Or from another source? As a result, the procedure is as follows: l_url := 'http://||G_HOSTNAME||:7777/pls/apex/f?p=109:29:::NO::P29_ID:'||C1.ID ;
The varialbe G_HOSTNAME would contain etiher "teleg1" or "teleg2" according to the APEX server that executes the PL/SQL procedure at this time.I hope I am clear.
Good day!

Use the functionowa_util.get_cgi_env . You'd be interested in CGI environment variables SERVER_NAME and SERVER_PORT.

How to dynamically change the host name in the Pages of the URL of the APEX
Dear gurus,
Please advise me on how to dynamically change the hostname in the URL used in the pages of the APEX.
For example: I have the below URL in one of the apex pages.
owa_util. REDIRECT_URL ("http://adminlxdb03.texas.org:7780/pls/htmldb ' |' / f?") p ='|| v ('APP_ID') | ": 151:" | " v ('APP_SESSION'));
in the case of a Migration of this apex from one server to another (for example, TEST the PROD box), this / these pages are wrong because the different host id name in the PROD box.
Is it possible that we can dynamically change the hostname in the URL used in the pages of the APEX.
for example
owa_util. REDIRECT_URL ("http://adminlxdb03.texas.org:7780/pls/htmldb ' |' / f?") p ='|| v ('APP_ID') | ": 151:" | " v ('APP_SESSION'));
should become
owa_util. REDIRECT_URL ("http://adminetuxdb09.texas.org:7780/pls/htmldb ' |' / f?") p ='|| v ('APP_ID') | ": 151:" | " v ('APP_SESSION'));
It's adminlxdb03.texas.org (TEST) at adminetuxdb09.texas.org (PROD).
If the page has no error...
Please notify.
Thank you
SheikYou don't need to provide the hostname while redirecting in the pages of the apex
owa_util. REDIRECT_URL ('f? p ='| v ('APP_ID') |) ": 151:" | " v ('APP_SESSION'));
should work just fine.

Firefox crashes when I open it (Mac OS). How can I retrieve the addresses of all the Web sites in my bookmarks before attempting to reinstall firefox?
ID of the Crash
c427216d-8a2f-8b48-Beca-50074acfbc6b
User Agent
Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_4; TI - TI) AppleWebKit/533.16 (KHTML, like Gecko) Safari/533.16 Version/5.0
Yes, all your personal information is stored in your profile folder.
Again, see back up and restore the information contained in the profiles of Firefox to manually back up your profile folder. This article also contains information about what information is stored where (for example, Places.sqlite for bookmarks and history).
Then save that manually uninstall Firefox and delete the profile folder. Then you should be able to do a completely clean install and then restore your settings accordingly.

How can I download the server behavior extensions?
How can I download the server behavior extensions?
the page will have to be carried out has been an HTML page.
You cannot use the old panels of database server & PHP on ordinary HTML files. They need to be saved as .php files to analyze the code on the server side.
If your remote & local test server uses PHP 5.5 or higher, I do not recommend using panels of database server & deprecated. The code is incompatible, obsolete & non-secure.
Further, you should be manually coding with (improved) MySQLi or PDO.

How can I retrieve the name of the server and the database to a system dsn
Hello
I am trying to create a database that will be used by many stores. Each store has its own server and the database and the access runtime version. I want to create a system dsn name, but allowing the administrator to modify the server and the database for that dsn and then, when you connect to the database, the database must be able to find this DSN and the 'new' name of the server and name of 'new' database and connect to point to this server and the database tables. I don't have a login form and I can get the name of the dsn, but I can't find a way to get the server name and database name for that dsn. Does anyone know a way to retrieve this from the registry. I can see it using regedit but have no idea on how to get this in vba access.
This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)* -
How to dynamically access the SQLite result set?
I want to dynamically access the SQLite result set. Since webworks does not support the "PRAGMA table_info (table_name); I save all newly created information tables in a single two-column table called schema. schema has two columns, table_name, and column_name.
So I created a function to dynamically access the data in the table. I use the item = results.rows.item (i) and that the data access with item.column line.
column is a variable that will receive the value of a schema representative of column_name. When I alert (column) I get the column_name is correct, but when I used item.column my results are "not defined".
any advice on how to solve this issue.
I managed to solve this issue. The solution is the following: the normal way to access the data of the variable item = results.rows.item (i) is item.column (where the column is the name of the column in the database table. To access the data dynamically, I Specifies a var col1 to assign different values in col1. I then access the data in the database using point [col1] hope that makes sense.
