Debug oracle forms how to#

When we enable the trace it will give the trace file location (This location will be the location of USER_DUMP_DESTINATION parameter of database).ДЄfter you save the form you can stop tracing by selecting вЂNo TraceвЂ™ again from Help -> Diagnostic -> Trace -> No Trace So after we fill all the values in the fields, we can start the tracing so that the initial select statement does not come in trace file. Example in my case I wanted to check the last insert/update DML statements that gets fired when we save the form. Be careful while enabling SQL trace with wait and binds as this will make the trace file huge.ДЄlso we can start the tracing in the middle of forms sessions also. вЂRegular TraceвЂ™ gives the least information and вЂTrace with Binds and WaitsвЂ™ (level 12) gives maximum information. We can enable tracing by selecing on of the options from here. Here we have many options available (default is вЂNo TraceвЂ™). When we open the form we can see on the menu option SQL tracing is used to track those DML queries to debug the issue. This will have some insert and updates command in the backend which will get executed when we save the form. In my case I have a forms where I am entering few values and then saving the form.

We will discuss couple of methods for enabling the tracing and see how that can help us in diagnosing the issue.ДЇirst we see how to enable a normal SQL tracing. Many types of tracing are available in forms. One of the best way to get such information is using tracing. For such situation we need to get more information about the issue we are facing in forms. To destroy a global variable and release its memory, use the ERASE built-in procedure: Erase('GLOBAL.Some times we need to diagnose the issue or error coming in forms. In assignments: v_blog_value := :global.my_blog In messages: message('My blog is ' || :global.my_blog) :GLOBAL.ur_globalvar := 15 ДЄfter declaration, global variables can be used in the form as normal variables in messages or assignments. Or following but numeric values will be converted to character by oracle. Since Oracle converts the value to character therefore In both methods if numeric value is needed following methods can be used. Second method available is to use the вЂњDEFAULT_VALUEвЂќ, in following example вЂњmy_blogвЂќ is the variable that we want to declare as global variable and вЂњвЂќ is the value we wish to assign. In Oracle Forms 10g storage size for global variables in 4000 bytes.В In order to use global variables inВ Oracle Forms following two methods are available:ДЇirst method available is to use the вЂњ:globalвЂќ keyword, in following example вЂњ my_blogвЂќ is the variable that we want to declare as global variable and вЂњ вЂќ is the value we wish to assign. In case you want to use a numeric value for global variable then remember that Oracle will convert it to character, therefore value needs to be converted to number for usage.Дeclaration of global variables is done through initialization, if used directly without initialization results in an error. Global variables in Oracle Forms always store the data as character of up to 255 for all kinds of usages. Similarly, Oracle Forms also support Global variables. In any programming language global variables play an important role in making data exchange and data persistence possible.
