Hi,
As you know RAC database is sahred database for 2 or more instanses (or nodes).
2 or more instances is active - active runing on a RAC database. But, RAC One Node is new in Oracle Clusterware, it is active - passive confioguration for
Oracle RAC Database, when active node or instance is fail, then Passive node is activating.

Is there any way to track what reports are actively running on BOE?

Good Afternoon.
I am looking for a way to track the names of what reports are currently being run on Business Objects. We are on Business Objects Enterprise XI R2 SP3 and from what Iu2019m aware, the servers can show the administrators how many connections and how many jobs are running, and the auditing command can track when a report has completed/failed (from what I understand), but nothing really tells us what reports are actively being run.
The purpose of this is to measure impact for an emergency restart of the server, track down reports that are taking up system resources, and debugging issues involved with the SDK.
Background: We have several reports hosted on Business Objects, both Crystal Reports and Web Intelligence. These reports go to different universes and databases and use several different accounts depending on the project (no central generic accounts to the databases). Sometimes when people are running several large reports (some being upwards of 1 million rows) the users will open one, leave it to run and go to open several others, killing our session limit and resources on the server. In addition, there have been times in development that restarts have been required but there was no way to tell what reports were running, just the number of them, and in several different spots (RAS, Page server, etc.).
Wish list (If my first priority is answered, Iu2019m also looking for the following):
- One to one associations of what reports are being run by what users.
- A centralized location to see what reports are being run by users opening them and what reports are being run by users scheduling them.
- The ability to u201Ckillu201D a report that is taking too long to run by a user.
- Possibly an interactive dashboard showing the number of active reports verses the serveru2019s limit, what reports are set in queue, etc.
- The u201Cstageu201D a report is running in, so if someone is running a report but its stuck at the prompt for a variable stage, querying data from the database, getting data back from the database, producing and processing the data to the screen, etc.
If Iu2019ve missed something in the Business Objects tools or if someone knows of a way to extract this type of data from the Business Objects server (3rd party tool or custom fix) I would appreciate the assistance. Thank you for your time.

Brian,
I don't know if you tried using the Query Builder.
The query below (or some modification of it) may be of some help.
SELECT
SI_SCHEDULEINFO, SI_NAME
FROM
CI_INFOOBJECTS
WHERE
SI_SCHEDULE_STATUS = 1
The SI_SCHEDULEINFO.SI_SUBMITTER property in the query result will give you the BOUSER value of the user that submitted the job.
SI_SCHEDULE_STATUS takes the following values:
0     The job is currently being processed by the job server.
1     The job completed successfully.
3     The job failed. Check error message.
8     The job is paused.
9     The job has not started because dependencies are not satisfied (e.g. Events)
Best,
Srinivas

What is an "active connection" to the FMS server?

Hi,
I am wondering exactly what are considered "active connections" to an FMS server?
Is it only the RTMP/RTMFP NetConnections, or do NetStreams also count?
Thanks

Only netConnections. You can't connect a netstream without a netconnection so they don't count on the connection count number.

What is ESN Activated means? (Always included in the IMEI Check Services)

What is ESN Activated Really Means? I always find this info in about every IMEI CHECK SERVICE RESULTS. But, never actually know its true meaning. Thanks

ESN stands for electronic serial number. I stay away from those IMEI check sites, since most of the time something in the information they provide is wrong.

what does 'the activation server is temporarily down' mean?

That you may have jailbroken your phone. You may have used that computer to jailbreak a phone. You may have a bad hosts file on the computer because of that. There are many reasons, but generally those are the main ones. According to this http://www.apple.com/support/systemstatus/ there are no system outages.

What is the activity quantity in KSII and how is it arrived

Hi,
Could any body help me to understand what is the activity quantity in KSII. How will we arrive at the figure we get when we run KSII.
I know the that we would be giving theplanned cost in KP06, planned activity quantity in KP26 and then when we run the price calculation in KSPI we get the total price for the cost center and the activity type. This is what is the planned total price for a period.
I am unable to understand the differece between the planned and the standard cost. Please help me with an example.
Standard cost is planned cost * actual hours, correct me if I am wrong.
Please assist,
Regards,
Shilpa.

Hi Shipla ,
You have two questions :-
1. How to get activity quantity in KSII
KSII is actual price calculation . Actual Price = Actual Cost/ Actual Qty..
Actual quantty is derived from quantity confirmed in production/process order and direct activity allocation done to the cost center . If you see a Cost Center Plan/Actual variance report.. you can see the actual quantity booked in a process Order . Actual Cost is the cost booked into the cost centers ..from FI/CO /IO settlement etc ..
During Actual costing , activity costs are generally booked at plan rate ( KP26). In KSII , actual price is computed and the difference is allocated to the cost centers.
2. Standard cost is planned cost * actual hours
No , plan cost is the cost you have planned for the year . You can use the plan cost to create a cost estimate . This cost estimate can be used as standard cost or for any anaylsis purpose..
Always remeber that purpose of product cost planning is to compute product cost estimate . This estimate may be used as standard costs.
Hope it clarifies..

RAC Active Active cluster failover time

Hi,
In a RAC active active cluster , how long does it take to failover to the surviving instance.
As per the docu I understand that rollback is done just for the select statements and not others. Is that correct?

RAC is an active-active cluster situation by design.
A failover from a session from a stopped/crashed instance to a surviving one can be implemented in several ways.
The most common way to do failover is using TAF, Transparent Application Failover, which is implemented on the client (using settings in the tnsnames.ora file)
When an instance of a RAC cluster is crashed, the surviving instances (actually the voted master instance) will detect an instance is crashed, and recover the crashed instance using its online redologfiles. Current transactions in that instance will be rolled back. The time it will take is depended on activity in the database, thus the amount to recover.

Safari 6: What happened to "Activity" view? Also Web Inspector Network view doesn't work.

Hi all,
I "upgraded" to Safari 6 and while it's super-fast and snappy as ****, I'm missing two features:
1) Activity view is gone! It was the easiest way to see what kind of crap websites are loading and you could double click on files and view them. Now that's gone.
2) I then tried using Web Inspector to try to track down a FLV file that was being loaded (something that worked with old Safari) and I couldn't do it anymore... Flash loading is not visible in Safari 6 and yet it was in previous Safari.
Ugh... new Safari is a great but they took two of my favorite options
Is there something I'm missing or are these features really gone?

If you are writing a Web or JavaEE application, activation.jar should be provided automatically by server (e.g. GlassFish, JBoss, etc.). If it is not working, please post more details (NetBeans version, server brand and version, JDK version, error messages encountered, etc.)

What is Retro active rebates and how there are configured

Hi,
What it means by retro active rebates and how there are configured. Please also explain how rebates settlement will happen...
Regards
Sankar

Hi,
Retroactive Rebate Processing:
You can create rebate agreement for which the validity period start date lies in the past. The system takes in to account all the rebate relevant billing documents that were created between the validity start date & the date you created the rebate agreement. In addition to the credit memo request, the system creates a correction sales doc (type B2) automatically for this amount.
Create the rebate agreement in the usual way. The system recognizes that the rebate agreement is retroactive.
