  • oci_set_action()

    (PHP 5 >= 5.3.2, PHP 7, PECL OCI8 >= 1.4.0)

    Sets the action name

    说明

    oci_set_action(resource $connection,string $action_name): bool

    Sets the action name for Oracle tracing.

    The action name is registered with the database when the next 'round-trip' from PHP to the database occurs, typically when an SQL statement is executed.

    The action name can subsequently be queried from database administration views such asV$SESSION. It can be used for tracing and monitoring such as withV$SQLAREAandDBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE.

    The value may be retained across persistent connections.

    参数

    $connection

    Oracle 连接标识,由oci_connect(),oci_pconnect(),或oci_new_connect()返回。

    $action_name

    User chosen string up to 32 bytes long.

    返回值

    成功时返回TRUE,或者在失败时返回FALSE

    范例

    Example #1 Setting the action

    <?php
    $c = oci_connect('hr', 'welcome', 'localhost/XE');
    // Record the action
    oci_set_action($c, 'Friend Lookup');
    // Code that causes a round-trip, for example a query:
    $s = oci_parse($c, 'select * from dual');
    oci_execute($s);
    oci_fetch_all($s, $res);
    sleep(30);
    ?>
    
    // While the script is running, the administrator can see the actions
    // being performed:
    sqlplus system/welcome
    SQL> select action from v$session;
    

    注释

    Note:Oracle 版本需求

    当 PHP 是与 Oracle 数据库 10g 及更新版本的扩展库链接时,此函数可用。

    Tip

    性能

    使用旧版的 OCI8 或 ORACLE 数据库,可使用 OracleDBMS_APPLICATION_INFO包来设置客户端信息。这比使用oci_set_client_info()较低效。

    Caution

    Roundtrip Gotcha

    一些 OCI8 函数会导致 Roundtrips.对数据库来说当启用结果缓存时,查询可能不产生Roundtrips。
