    With OWA_OPT_LOCK

  • Types

  • Preview

    The OWA_OPT_LOCK special function contains routines that implement optimistic locking strategies to avoid missing updates.

    It checks to see if the line that a particular user wants to change has not been edited by the same person.

    PL/SQL Gateway cannot use traditional database locking methods because HTTP is a stateless standard protocol. The OWA_OPT_LOCK package provides workarounds for lost updates:

  • The built-in hidden fields method stores previous values ​​in hidden arenas in the HTML page. When a particular user requests an update, PL/SQL in each of our gateways checks these values ​​against the current state of the database. The operation is only updated if the values ​​match. To use this method, call the procedure owa_opt_lock.store_values

  • The checksum route stores the checksum instead of its own values. To use one method, call the owa_opt_lock.checksum function.

  • These procedures are optimistic. They do not prevent other users from updating, although they will opt out of the current renewal if an update occurs.

    Types

    This data type is a PL/SQL table for storing ROWIDs.

    VCARRAY TYPE IS VARCHAR2(2000) INDEX TABLE BY BINARY_INTEGER

    Summary Of OWA_OPT_LOCK Routines

    CHECKSUM Functions

    This function returns the checksum for a given string or row in a table. For a string within a cubic string, the function calculates a Checksum value based primarily on the string’s message values. This feature is available in two versions.

    The first version returns a checksum based on a single string. A “pure” 32-bit checksum is performed by the database at just 1 protocol per second

    based on the Internet.

    Version returns the checksum set for the values ​​for a short period of time in the table. This is a “dirty” 32-bit controlUmmah based on this Internet Protocol 1.

    OWA_OPT_LOCK.CHECKSUM( p_buff in VARCHAR2) RETURN NUMBER;OWA_OPT_LOCK.CHECKSUM( p_owner in VARCHAR2, p_tname to VARCHAR2, p_rowid to ROWID) RETURN NUMBER;

    GET_ROWID Function

    This function returns a specific data type ROWID from OWA_OPT_LOCK.VCARRAY DATA TYPE.< /selected . back. p>OWA_OPT_LOCK.GET_ROWID( p_old_values ​​in Vcarray) REFUND ROVID;

    STORE_VALUES Procedure

    This procedure saves the column values ​​created by the row you want to update later. Values ​​are stored in hidden HTML form elements.

    OWA_OPT_LOCK.STORE_VALUES( p_owner in VARCHAR2, p_tname to VARCHAR2, p_rowid to ROWID);

    Before adding to the string, compare these values ​​with the current values ​​of the string to ensure that the string values ​​have not changed. If you find that the values ​​have changed, you can notify certain users and let them manage the update.

  • A hidden element form is created on the table owner. The name that includes the element is “old_p_tname” if p_tname is the workspace name. element value,whose type is owner_name.

  • A hidden element form is created to define a table. The element name can be “old_p_tname“, where p_tname is the name of the entire table. The value of the element is the name of the array.

  • An element is created for each individual column in a row. The element name is “old_p_tname“, where p_tname is the desktop name. The value of the element is the value of the column.

  • Function

    This function verify_values​​​​​​​​​​​​​verifies that the values ​​displayed in this row have been updated with the latest request. Use this function with the STORE_VALUES procedure.

    OWA_OPT_LOCK. check_values( p_old_values ​​in vcarray) BOOLEAN RETURN;
