If you simply want the name of the most recently executed subprogram, you will have to parse the string.

Dbms_utility.format_call_stack Example

The only difference is that the DBMS_UTILITY.FORMAT_ERROR_STACK function appends a line feed! In this case, if further name translation is desired, then you must call the DBMS_UTILITY.NAME_RESOLVE procedure on this remote node. Then the above call will mark the oc_orders view invalid. The following example recreates the DISPLAY_CALL_STACK procedure to use the UTL_CALL_STACK package, then re-runs the test. -- Procedure to display the call stack.

Syntax DBMS_UTILITY.PORT_STRING RETURN VARCHAR2; Pragmas pragma restrict_references(port_string, WNDS, RNDS, WNPS, RNPS); SQLID_TO_SQLHASH Function This function converts a SQL ID into a hash value.

There is, however, always room for improvement, and that is why Oracle Database 12c added UTL_CALL_STACK. Dbms_utility.format_error_backtrace In Oracle Forms I then use the format_call_stack_12c procedure (in Listing 2) in the pkg.do_stuff procedure and execute that procedure, as shown in Listing 3. Syntax DBMS_UTILITY.OLD_CURRENT_USER RETURN VARCHAR2; PORT_STRING Function This function returns a string that identifies the operating system and the TWO TASK PROTOCOL version of the database. Syntax DBMS_UTILITY.DATA_BLOCK_ADDRESS_FILE ( dba NUMBER) RETURN NUMBER; Parameters Table 141-14 DATA_BLOCK_ADDRESS_FILE Function Parameters Parameter Description dba Data block address.

How To Find Which Line Error Was Raised In Oracle

Syntax DBMS_UTILITY.GET_TIME RETURN NUMBER; Return Values Time is the number of 100th's of a second from the point in time at which the subprogram is invoked. The biggest problem I've found is that the pcode doesn't include blank lines and in long blocks the line numbers can get seriously out of whack. Dbms_utility.format_call_stack Example object_type Type of object, must be T (table) or I (index). Dbms_utility.format_error_backtrace 11g Here is your quiz for this article.

CURRENT_EDITION : The edition of the subprogram associated with the current call. Not the answer you're looking for? For instance, in the case of two negative numbers, application logic must allow that the first (earlier) number will be larger than the second (later) number which is closer to zero. In this case, it is necessary to parse the backtrace string and retrieve just the top-most entry. Format_error_stack Vs Format_error_backtrace

In Listing 4, I create and execute a function named BACKTRACE_TO that “hides” the calls to the UTL_CALL_STACK subprograms. They might, for example, take screen scrapes of their scheduling systems' output as application logs and be satisfied with the level of information demonstrated above. instance_record TYPE instance_record IS RECORD ( inst_number NUMBER, inst_name VARCHAR2(60)); TYPE instance_table IS TABLE OF instance_record INDEX BY BINARY_INTEGER; The list of active instance number and instance name. http://upintheaether.com/how-to/how-to-run-error-checking-utility-in-windows-vista.php ERROR_MSG : The error message associated with the current line in the error stack.

Dbms_utility.format_error_stack Vs Sqlerrm COMMA_TO_TABLE Procedures These procedures converts a comma-delimited list of names into a PL/SQL table of names. Usage Notes This procedure uses the DBMS_OUTPUTpackage to display results, and so you must declare SET SERVEROUTPUT ON if you wish to view dependencies.

Syntax DBMS_UTILITY.GET_CPU_TIME RETURN NUMBER; Return Values Time is the number of 100th's of a second from some arbitrary epoch.

Since no objects can depend on bodies, there are no cascaded invalidations. One of the greatest improvements of UTL_CALL_STACK over DBMS_UTILITY .FORMAT_CALL_STACK is that you can obtain a unit-qualified name, which concatenates the unit name, all lexical parents of the subprogram, and the Exceptions Table 141-21 INVALIDATE Exceptions Exception Description INV_NOT_EXIST_OR_NO_PRIV Raised when the object_id argument is NULL or invalid, or when the caller does not have CREATE privileges on the object being invalidated Oracle Call Stack Trace compatibility The compatibility setting of the database determined by the "compatible" init.ora parameter.

Thanks. Notice that there is no error handling in any of the procedures; it is most significantly lacking in the top-level proc3 procedure. The output includes the procedure names in the package as well as the associated line numbers of the calls. Check This Out c_name_delim CONSTANT CHAR (1) := '"'; c_dot_delim CONSTANT CHAR (1) := '.'; c_line_delim CONSTANT CHAR (4) := 'line'; c_eol_delim CONSTANT CHAR (1) := CHR (10); 2.

Having compiled the new proc3 , when I run it inside SQL*Plus I see the following output: SQL> SET SERVEROUTPUT ON SQL> exec proc3 calling proc2 calling proc1 running proc1 ORA-01403: BEGIN P5(); EXCEPTION WHEN OTHERS THEN Log_Errors ( 'Error_Stack...' || Chr(10) || DBMS_UTILITY.FORMAT_ERROR_STACK() ); Log_Errors ( 'Error_Backtrace...' || Chr(10) || DBMS_UTILITY.FORMAT_ERROR_BACKTRACE() ); DBMS_OUTPUT.PUT_LINE ( '----------' ); END Top_With_Logging; / SHOW ERRORS Recognizing that I will be needing to parse the contents of a string based on various delimiters, I define a number of constants to hold these delimiter values.

Each setting can be specified only once else inv_malformed_settings exception will be raised. That is, a call to INVALIDATE will not actualize the object in the current edition. The "ORA-06512" error is not included, but this is implied because it is a backtrace message. GET_PARAMETER_VALUE Function This function gets the value of specified init.ora parameter.
