Event Based Jobs

Hi,
I have 3 jobs A, B, and C (we do not want to use a chain).
My intention is for the jobs to run in sequence, A->B->C, however their run times should not overlap.
Also I want to specify the multiple event conditions.
For example B should not start if A is running and C should not start if A or B are running.
I tried the specify the below event_condition for job C. It is not working.
Event_Condition => tab.user_data.object_name=''EBJ_A'' and tab.user_data.object_name=''EBJ_B''
Please provide any suggestions that I can use.
Thanks,
Sreenath.

SEE THIS EXAMPLE:
The following example creates a chain where first my_program1 runs. If it succeeds, my_program2 runs; otherwise, my_program3 runs.
BEGIN
DBMS_SCHEDULER.CREATE_CHAIN (
chain_name => 'my_chain2',
rule_set_name => NULL,
evaluation_interval => NULL,
comments => NULL);
END;
--- define three steps for this chain.
BEGIN
DBMS_SCHEDULER.DEFINE_CHAIN_STEP('my_chain2', 'step1', 'my_program1');
DBMS_SCHEDULER.DEFINE_CHAIN_STEP('my_chain2', 'step2', 'my_program2');
DBMS_SCHEDULER.DEFINE_CHAIN_STEP('my_chain2', 'step3', 'my_program3');
END;
--- define corresponding rules for the chain.
BEGIN
DBMS_SCHEDULER.DEFINE_CHAIN_RULE ('my_chain2', 'TRUE', 'START step1');
DBMS_SCHEDULER.DEFINE_CHAIN_RULE (
'my_chain2', 'step1 SUCCEEDED', 'Start step2');
DBMS_SCHEDULER.DEFINE_CHAIN_RULE (
'my_chain2', 'step1 COMPLETED AND step1 NOT SUCCEEDED', 'Start step3');
DBMS_SCHEDULER.DEFINE_CHAIN_RULE (
'my_chain2', 'step2 COMPLETED OR step3 COMPLETED', 'END');
END;

Query on event based job in a client schema and not SYS schema

Hi, I am fairly new to oracle job scheduler and wanted your inputs on how to create a event based job that sends a mail based on success of another job.
I was able to implement this with the jobs being created under SYS schema. I did get email notifcation when errors were logged in exception table.
However, now the requirement has changed to create the jobs under a client specific schema.
The jobs got created successfully in CLIENT schema but the event based job is not working. It does not send the email notification.
I feel this is to do with not correctly subscribing to the event queue {sys.scheduler$_event_queue}.
Can CLIENT schema use the agent "AGENT" created under SYS to subscribe to the Scheduler event queue {sys.scheduler$_event_queue}? CLIENT is the schema in which the all jobs and procedures are created.
BEGIN
DBMS_AQADM.ENABLE_DB_ACCESS('AGENT', 'CLIENT');
END;
--Main Job that will load data and errors will be logged into exception table
BEGIN
dbms_scheduler.create_job( job_name=> 'CLIENT.LOAD_DATA',
job_type=>'PLSQL_BLOCK',
job_action=>'BEGIN CLIENT.p_loaddata;
END;',
start_date=>systimestamp,
repeat_interval=>'FREQ=MINUTELY;INTERVAL=1;',
number_of_arguments=>0,
enabled=> true);
END;
--set raise_events attribute = job_succeeded for main job
BEGIN
DBMS_SCHEDULER.set_attribute ('CLIENT.LOAD_DATA', 'raise_events', DBMS_SCHEDULER.job_succeeded);
END;
--Event Job that will send email based on condition. Condition is checked in procedure CLIENT.p_check_sendmail; If errors are found in the exception table, this job will raise exception and will be JOB_FAILED status. This job will send a email notification.
BEGIN
DBMS_SCHEDULER.create_job (       job_name          => 'CLIENT.EMAIL_JOB',
job_type          => 'PLSQL_BLOCK',
job_action        => 'BEGIN CLIENT.p_check_sendmail;                                   END;',
event_condition => 'tab.user_data.event_type = ''JOB_SUCCEEDED'' and tab.user_data.object_name = ''LOAD_DATA''',
queue_spec        => 'sys.scheduler$_event_queue,AGENT',
enabled          => true);
END;
BEGIN
dbms_scheduler.add_job_email_notification ( job_name => 'CLIENT.EMAIL_JOB',     recipients => '[email protected]',events => 'JOB_FAILED');
END;
Is the way i am subscribing to the event queue correct? Could you please share an example/document of event based job in a schema other than SYS and how subscription is being done to event queue?
Thanks

Hi,
It's a good decision you made because you shouldn't create objects in the SYS schema. I see you're using the add_job_email_notification procedure, so I'm assuming you're on 11g onwards.
This procedure is meant to make the job easy for you. That is, you don't need to worry about setting up AQ, the procedure does it all for you. All you need to do is setup the mail server if not already done, and call this procedure to add the mail notification. That's it.
You can also specify a filter to the add_job_email_notification procedure, so maybe you could specify directly your CLIENT.LOAD_DATA job to this procedure.

Documentation for tab.user_data with event based jobs

Hi,
Are all the atributes for tab.user_data when used as part of an event based job documented somewhere?
I have been looking but all I can find are examples rather than explicit documentation.
Thanks
Pete

Hi Pete,
The type of the object tab.user_data is the type used to create the AQ queue with. So it varies depending on the type you used to create the queue with.
If you are consuming messages from the scheduler event queue, the type is sys.scheduler$_event_info and to figure out what fields it has you can use
desc sys.scheduler$_event_info
Hope this helps,
Ravi.

Scheduler - Event Based Jobs

Hi,
I've been trying to create an event based job dependent on multiple jobs. I tried queuing, but it seems like it can only hand one Job at a time. Also, chains were recommended to me, but I want the Job to run on the dependence on the Job that ran on specific program at the specific time. I currently know that chains can only handle, programs, other chains and/or events.
In my mind chains wouldn't work, because If I wanted to run Job3 dependent on the outcome of Job1 running Program1 and Job2 running Program2, chains wouldn't be able to accomdate that. For it to happen in chains I would have to attach Program1 and Program2 to the new chain Job and that is not exactly what I would want.
Can anyone help/clarify this situation for me. Thank you.
Tony

Hi Tony,
So the requirement is to run a job after 2 prior jobs have completed.
There are two ways I can think of to do this, both using events. In both cases you need to set job A and job B to raise events on completion (succeeded, failed or stopped) and setup an agent for the Scheduler event queue in the schema in which you are working
dbms_scheduler.add_event_queue_subscriber('myagent')
In order to get Job C to start after jobs A and B have completed there are 2 options.
1) Let job C point to a chain and start running whenever job A has completed. The chain will have 2 steps, one event step waiting on B and one that runs your task C. An event step does nothing but wait for a particular event and complete successfully when the event is received. The second step will run when the event step waiting on job B has completed.
So your chain would look something like
begin
dbms_scheduler.create_chain('chain1');
dbms_scheduler.define_chain_event_step('chain1','stepB',
'tab.user_data.object_name = ''JOB_B'' and
tab.user_data.event_type IN(''JOB_SUCCEEDED'',''JOB_FAILED'',''JOB_STOPPED''',
'sys.scheduler$_event_queue,myagent');
dbms_scheduler.define_chain_step('chain1','stepC','finalTaskProg');
dbms_scheduler.define_chain_rule('chain1','true','start stepB');
dbms_scheduler.define_chain_rule('chain1', 'stepB completed', 'start stepC');
dbms_scheduler.define_chain_rule('chain1', 'stepC completed', 'end');
dbms_scheduler.enable('chain1');
end;
And your job would point to the chain and run whenever job_A completes (similar condition and queue_spec). It would keep waiting till job_B runs and then the final task would run and it would complete.
2) The second way is to require job_A to insert a row into a table somewhere. Rule conditions can access table data so you could have job_C have an event condition which checks for a completion event for job_B and checks the table to see whether job_A has completed. Then the code you run should then remove the row in the table
e.g.
queue_spec=>'sys.scheduler$_event_queue,myagent'
event_condition=>'tab.user_data.object_name = ''JOB_B'' and
tab.user_data.event_type IN(''JOB_SUCCEEDED'',''JOB_FAILED'',''JOB_STOPPED''' and
(select count(*) from mytab where col='job_A')>0'
Then when running C do - delete from mytab where col='job_a';
Both of these assume that job_A always completes before job_B but both of these will then run job_C after job_B completes. Modifying either of these so that either job A or B runs first is also possible by having another job that waits on A rather than B.
Hope this helps, if you have any more questions, let me know.

How to limit the number of parallel instances of a given event-based job?

Hi,
DB version : 11.2.0.3
I'm using an event-based job with parallel_instances attribute set to true.
It works perfectly fine, messages are enqueued then dequeued and processed simultaneously by separate instances of the same job.
Now, I'd like to limit the number of parallel instances of this job running at the same time, say to an arbitrary number n.
What would be the best way to do that?
Maybe using a notification callback is a better option in this case?
Thanks in advance for any input.

Time and event-based jobs

Jobs scheduled based on time in DBMS_SCHEDULER. Can we changed to event-based without dropping the job?
Thanks in advance.

Hi,
You can try this :
- disable the job
- set event_spec to be NULL for the job e.g.
exec dbms_scheduler.set_attribute_null('j1','event_spec')
- use set_attribute to set your time-based schedule
- re-enable the job
This should work.
Hope this helps,
Ravi.

Event based job

we have a job that needs to be restarted after db reboot,is it possible to create an event based inside oracle that starts the queue and our main job for us ?
v11.2

Hello;
Oracle has an System Event Trigger "AFTER STARTUP" which could be used for this.
"Ask Tom" has a note on this with example :
http://asktom.oracle.com/pls/apex/f?p=100:11:0::::P11_QUESTION_ID:49818662859946
( This shows after logon, but you should be able to use the example with the other trigger )

Can't Seem to Get my Event Based Job To Execute

What makes this slightly different than other posts on this topic is that we want to use our own queue/payload object rather than the built-in SCHEDULER$_EVENT_QUEUE. There are many reasons for this. What follows in under 11gR2 (11.2.0.3)
So, the following code blocks are just for a proof of concept piece intended to create a simple job and to have it fired based on the arrival of a message in a queue. (Something we have a requirement to do) The issue that I just can't seem to resolve is that, for some reason, the scheduler object never triggers the job. I can't find any trace or alert log entries to help me diagnose. What I do know is that the queue itself is fine (dequeues and enqueues work normally). The object payload type is fine (All of these tested from the EVENT_JOB_MGR package provided below).
Here's the PL/SQL Type that is the payload object of the queue and is also referenced in the package:
CREATE OR REPLACE TYPE RUN_MSG AS OBJECT
STATUS VARCHAR2(255)
Here are the queue and queue table:
BEGIN
DBMS_AQADM.CREATE_QUEUE_TABLE
    QUEUE_TABLE           =>        'JUPSHAW.EVENT_JOB_QT'
   ,QUEUE_PAYLOAD_TYPE    =>        'JUPSHAW.RUN_MSG'
   ,COMPATIBLE            =>        '10.0.0'
   ,STORAGE_CLAUSE        =>        '
                                     TABLESPACE RISKDM_DATA'
   ,SORT_LIST             =>        'ENQ_TIME'
   ,MULTIPLE_CONSUMERS    =>         TRUE
   ,MESSAGE_GROUPING      =>         0
   ,SECURE                =>         FALSE
End;
BEGIN
DBMS_AQADM.CREATE_QUEUE
    QUEUE_NAME          =>   'JUPSHAW.EVENT_JOB_Q'
   ,QUEUE_TABLE         =>   'JUPSHAW.EVENT_JOB_QT'
   ,QUEUE_TYPE          =>   SYS.DBMS_AQADM.NORMAL_QUEUE
   ,MAX_RETRIES         =>   0
   ,RETRY_DELAY         =>   0
   ,RETENTION_TIME      =>   -1
END;
DECLARE
aSubscriber sys.aq$_agent;
BEGIN
aSubscriber := sys.aq$_agent('SCHEDULER$_EVENT_AGENT',
                              0);
dbms_aqadm.add_subscriber
     ( queue_name     => 'EVENT_JOB_Q'

END;
BEGIN
SYS.DBMS_AQADM.START_QUEUE
    QUEUE_NAME => 'JUPSHAW.EVENT_JOB_Q'

I call the ENQUEUE_JOB_STATUS_MSG method to stick a message on the queue. I can confirm that it can be dequeued and logged using the DEQUEUE_JOB_STATUS_MSG method in the package. However, nothing seems to happen (at all) as far as the scheduler job when a message is put on the queue. I am thinking it should dequeue the message with status set to SUCCESS and then, kick off the job.
Can anyone see why the above wouldn't work? Been stuck here for a couple of days.
Thanks,

Try to create job that react on event directly not using schedule.
BEGIN
    dbms_scheduler.create_job(job_name => 'EVENT_JOB',
                              program_name => 'EVENT_JOB_PROG',
                              event_condition => 'TAB.USER_DATA.STATUS = ''SUCCESS''',
                              queue_spec => 'EVENT_JOB_Q',
                              enabled => true,
                              auto_drop => FALSE);
END;
Check if your schedule EVENT_JOB_SCHED is enabled

EVENT BASED SCHEDULER

Hi All,
I have two databases lets say A an B.
I have a STORED PROCEDURE on DATABASE B which runs everyday via a schecduler at 8 in the morning.
This procedure basically picks up data from a TABLE in database A and processes it everyday.
Now I want to modify the scheduler from the current one that runs at say 8 to one that runs the STORED PROCEDURE whenever data is inserted into the table.
Is it possibble in ORACLE?
Datbase version is 10g
Any help would be highly appreciated.

Oracle Scheduler - Event Based Jobs.
One way of re-using it is, raising an Event trigger to Kick-off the jobs, preferably once data is inserted into tables. Definitely, this has to be done by the system performing the Inserts.

Events Based Scheduling

Database Ver. 11gR2 (11.2.0.2.0)
Hi Guys,
How do you run jobs in oracle scheduler based on events? I have a job that needs to run after the successful completion of another job. I don't want to use chains. I have searched on the web, but all the examples I see are where a temp table is created and a row is inserted and then another PL/SQL block is run to manually pass a 'GO' value. I am looking for the a job to raise the JOB_SUCCEEDED event and then another job kicks in based on this event.
Any detailed examples would be greatly appreciated. Also if using any other PL/SQL package, what necessary privileges would be required to execute that package.
Thanks in advance.
VB

Here is a simple example. You create a job, MY_JOB, that raises the job_succeeded event. You also create an event-based job, MY_JOB_CONSUMER, that consumes event messages from sys.scheduler$_event_queue but only for job_succeeded events raised by MY_JOB.
First you let the user subscribe to the Scheduler event queue using the ADD_EVENT_QUEUE_SUBSCRIBER procedure. “my_agent”, or whatever name you use, is the name of the Oracle Streams Advanced Queuing (AQ) agent to be used to subscribe to the Scheduler event queue. This call both creates a subscription to the Scheduler event queue and grants the user permission to dequeue using the designated agent. The subscription is rule-based. The rule permits the user to see only events raised by jobs that the user owns, and filters out all other messages:
DECLARE
   agent_already_subscribed_exp   EXCEPTION;
   PRAGMA EXCEPTION_INIT (agent_already_subscribed_exp, -24034);
BEGIN
   sys.DBMS_SCHEDULER.add_event_queue_subscriber ('my_agent');
EXCEPTION
   WHEN agent_already_subscribed_exp
   THEN
      NULL;
END;
/Then you create MY_JOB_CONSUMER:
BEGIN
   sys.DBMS_SCHEDULER.create_job (
      job_name          => 'MY_JOB_CONSUMER',
      job_type          => 'PLSQL_BLOCK',
      job_action        => '/* Add you code here */ NULL;',
      event_condition   => 'tab.user_data.event_type = ''JOB_SUCCEEDED'' and tab.user_data.object_name = ''MY_JOB''',
      queue_spec        => 'sys.scheduler$_event_queue,my_agent',
      enabled           => TRUE);
END;
/Now, MY_JOB_CONSUMER is waiting for a message to arrive in sys.scheduler$_event_queue. It will dequeue it only if the condition in event_condition is true.
Create a one time job, MY_JOB, set its raise_events attribute to job_succeeded and enable it:
BEGIN
   sys.DBMS_SCHEDULER.create_job (job_name     => 'MY_JOB',
                                  job_type     => 'PLSQL_BLOCK',
                                  job_action   => '/* Add you code here */ NULL;',
                                  start_date   => SYSTIMESTAMP AT TIME ZONE 'US/Pacific',
                                  auto_drop    => TRUE,
                                  enabled      => FALSE);
   DBMS_SCHEDULER.set_attribute ('MY_JOB', 'raise_events', DBMS_SCHEDULER.job_succeeded);
   sys.DBMS_SCHEDULER.enable ('MY_JOB');
END;
/When MY_JOB executes, it will enqueue a message in sys.scheduler$_event_queue. MY_JOB_CONSUMER will then pick it up and consume it.
Hope that simple demonstration helps.

2. How to link created event to the process chain in the same BI or BW system and as well as from
    externel BI system.
3. How link one process chain with other process chain (i.e, After completion of one process chain, it
    should trigger other dependent process chain)
Thanks and Regards,
Kotesh.

1). Doubt regarding first question.
For example, i would like to create time based event (it should be trigger daily at specified time),
where we have to maintain scheduling options while creating event.
When i checked SM62 there i found only two options a). Event name and b). Description.
Could please send any doucument link if you have.
Ans : You can use function modules like "BP_EVENT_RAISE" in a program and schedule the program to trigger.
2). For externel BIW system also same procedure we need to follow or any difference.
Ans : Externally you need to trigger the same event.
3). i found dependent process chain also had scheduling options as direct scheduling insted of start using meta chain or API. As you said dependent process chain should be mata chain. it seems dependent process chain may be Meta chain or Direct scheduilg.
Ans : Its your choice how you want to schedule it.You can either make that dependent chain a metachain or schedule it separately.
I found at the end of first process chain they kept one process like Raise event and second process chain connected with the help of raise event process event name. If you have any idea about this process could explain a bit more.
Ans : May be they are raising the event in the main chain and triggering the dependent chain using this event.
But Metachain is preferred for such thing.Though it does similar thing.
Hope this helps.

How to set a default start and/or end date for New Events based on trigger date.

I'm using the CalendarActivityListener to get current row when clicking on an existing event. As per previous posts this listener gives you access to event detail including Start Date, End Date, etc.
However, what I want to do is to default the start (and end) dates for New Events based on the trigger date.
I've tried the CalendarListener and can grab the Trigger Date from it - however, I can't see a way to pass this directly to the popup/dialog I'm using to create the new event.
At present I'm putting the TriggerDate into the ADFContext session scope e.g. ADFContext.getCurrent().getSessionScope().put("TriggerDate",calendarEvent.getTriggerDate());
Then, I've tried multiple approaches to try and "get" the TriggerDate from session scope to drop it into my new Calendar Event basically, I'm trying to default the InputField(s) associated with the Start Date using the value from the session - I've tried
1. setting the default value for the InputField in the jspx using a binding expression i.e. value="#{sessionScope.TriggerDate}" - this actually sets the value appropriately when the jspx is rendered but, when I go to create I get a NPE and I can't debug. I assumed that it might be a Date type issue - it would appear that CalendarListener provides a date of type java.util.Date and that the StartDate attribute of my VO/EO/table is a DATE and therefore requires oracle.jbo.domain.Date so I tried casting it - to no effect
2. Using a Groovy expression *(StartDate==null?adf.context.sessionScope.TriggerDate:StartDate)* in my calendar's EventVO to default the Start Date to the same result
Any thoughts or ideas?

John,
Thanks for that suggestion - could not get it to work. However, I did manage a different approach. I finally determined the sequence of events in terms of how the various events and listeners fire (I think).
Basically, the CalendarActivityListener fires, followed by the listener associated with the Calendar object's Create facet, followed finally by the CalendarEventListener - the final is where the TriggerEvent is available and then finally, control is passed to the popup/dialog in the Create facet. So, my approach of trying to set/get the TriggerDate in the user's HTTP session was doomed to failure because it was being get before it had been set :(
Anyway, I ended up adding a bit of code to the CalendarEvent listener - it grabs the current BindingContext, navigates through the DCBindingContainer to derive an Iterator for the ViewObject which drives the calendar and then grabs the currently active row. I then do a few tests to make sure we're working with a "new" row because I don't want to alter start & end dates associated with an existing calendar entry and then I define the Start and End dates to be the Trigger Date.
Works just fine. Snippet from the listener follows
BindingContext bindingContext = BindingContext.getCurrent();+
*if ( bindingContext != null ) {*+
DCBindingContainer dcBindings = (DCBindingContainer) bindingContext.getCurrentBindingsEntry();+
DCIteratorBinding iterator = dcBindings.findIteratorBinding("EventsView1Iterator");+
Row currentRow = iterator.getCurrentRow();+
if ( currentRow.getAttribute("StartDate") == null)+
currentRow.setAttribute("StartDate", calendarEvent.getTriggerDate());+
if (currentRow.getAttribute("EndDate")==null)+
currentRow.setAttribute("EndDate", calendarEvent.getTriggerDate());+
*}*

I need help with my event-based cue points with audio

Im having trouble with my video game project for my action script 3 class at school. Here is what i did, i made a game called Tailgate toss up. I filmed my character and rendered it in Adobe Premiere. I than brought my .mov file into After Effects and I put event-based cue points-
my first cue point at 0:00:03:13 called "loop"
my second cue point at 00:00:03:27 called "draw"
my third cue point at 00:00:05:24 called "bang"
my fourth cue point at 00:00:13:29 called "dead"
my fifth cue point at 00:00:14:29 called "You Lose"
my last cue point at 00:00:19:14 called "End"
Here is my action script 3 code
///first frame:
start_btn.addEventListener(MouseEvent.CLICK, startGame);
function startGame(event:MouseEvent){
gotoAndStop(2);
SoundMixer.stopAll()
stop();
///second frame:
stop();
var loopTime
var hitHim:Boolean = false;
var vConnection:NetConnection = new NetConnection();
vConnection.connect(null);
var vStream:NetStream = new NetStream(vConnection);
var client:Object = new Object();
client.onCuePoint = onCuePoint;
vStream.client = client;
var myVideo:Video = new Video(418, 480);
myVideo.y = 0; ///this adjusts where the video is, right now it is the size of the canvas which is 418,480
addChild(myVideo);
myVideo.attachNetStream(vStream);
vStream.play("michelle.flv");
var throw_bottle:Sound
throw_bottle = new Sound(new URLRequest("audio/throw_bottle.mp3")); //change to button noise, will add sound into ae file
target_mc.addEventListener(MouseEvent.CLICK, shoot);
target_mc.buttonMode = true;
target_mc.visible = false;
draw_mc.visible = false;
function onCuePoint(cuePoint:Object):void {
   if(cuePoint.name == "loop"){
loopTime = cuePoint.time;
    if(cuePoint.name == "draw"){
var randomLoop:Number = Math.random()*10;
if(randomLoop > 2){
vStream.seek(loopTime);
}else{
setChildIndex(target_mc, numChildren - 1);
setChildIndex(draw_mc, numChildren - 1);
target_mc.visible = true;
draw_mc.visible = true;
if(cuePoint.time == "5:24"){
draw_mc.visible = false;
target_mc.visible = false;
if(!hitHim){
vStream.seek(15);
if(cuePoint.name == "dead"){
vStream.close();
myVideo.clear();
gotoAndStop(3);
if(cuePoint.name == "end"){
gotoAndStop(3);
function shoot(event:MouseEvent){
throw_bottle.play();
hitHim = true;
///my third and last frame
playAgain_btn.addEventListener(MouseEvent.CLICK, playAgain);
function playAgain(event:MouseEvent){
gotoAndStop(2);
SoundMixer.stopAll()
stop();
When I have no audio it works perfectly, no problems. When I bring audio in i re-render it as a .mov file and bring it back into After Effects and add the cue points to it. Than i re-render it out again as a flv file. When i bring it into my flash project it will work when the looping variable does just one loop and my target will appear so you can click on it or not. But when the looping variable makes it loop 2 to 10 times it skips over the catching (the part of the clip if you clip the button) and goes directly to the dropping of the can, not giving you the option of clicking the button. So basically it skips the "draw" or second cue point of my game and goes to "You Lose" cue point.
Any suggestions?

Hi,

ATV and Photo App: Event based sorting disappeared

With the new update to the new Photo app, I can no longer view my photos from my TV (via my Apple TV) sorted by "events." Everything is sorted only by the actual folders the pictures are in, and since most of my photos are in the iPhotos Library "file" I can't sort these in any useful way.
Please fix this so that I can view the photos using the events based sorting method, which is how I have been organizing my photos for the last several years in iPhoto. Thank you.

Thanks for the reply. I went to iTunes --> Files --> Home Sharing --> Choose Photos to Share...and was able to click on the share "Photos" option from the pull down menu. This wasn't there yesterday so looks like there was an update in the meantime.
The problem is that the photos are shown in chronological order, so it's a pain to scroll all the way down to get to the more recent photos. Hopefully Apple will fix this soon, like the way they had it in iPhotos.
