Load balancing more than 6 paths

Hi
If RIP has 8 paths to the destination that have the same cost, it will choose 6 as the maximum number for load balance (assuming that RIP is configured for load balance among 6 paths and not 4).
How will it choose these 6 paths? Because when it chooses 6 paths, it has to ignore/drop 2 paths.
Please clarify.....
Thanks in advance!

It is actually CEF that is selecting which paths not RIP, as RIP will put all 8 paths in the RIB. It is then up to CEF to put those routes in the FIB based on its determination which paths to select.

Loading files more than 7 mb

Hello,
I know that there is an issue in BPEL loading files more than 7 mb. By increasing the JVM memory (using the mx parameter) we can bypass that (and it works fine). The problem is we loose the execution trace of the BPEL process in the management console. Is there any workaround for that ?
Thanks for you input / help on that issue.

By the way, since it is very large XML files with a lot of children nodes, we cannot split the XML file... ;-)

Can a master data will have loading from more than one data source

Dear gurus,
I have a master data object which has every day loading from one particular data source. Now I got a requirement to load data from another data source. If we load data from more than one data source , will there be any problem with data? Will it accept loading from more than one data source.?
Regards
Rs

Hi Ram,
We can load the data to target morethan one datasource.Thats advantage in BI compare to BW. It will accept loading from more than one datasource.but you have to take care about characteristic and attributes are the same in both datasources like that.

Buying Aperture 3 App, can it be loaded onto more than one computer?

Thinking about getting the Aperture 3 app for my computer and was wondering if the app can be loaded to more than one computer; or do I need to buy the boxed version from the store?

From the App Store FAQ, "..Apps from the Mac App Store may be used on any Macs that you own or control for your personal use."
You would need to log into the App Store on each Mac using the same Apple ID that was used to originally purchase the Aperture from the App Store.

Not able to load pages more than 3 times continuosly

Hi
JDeveloper 11.1.1.6, BPM/SOA 11.1.1.6, WLS 10.3.6, Database : MS SQL Server 2008 R2
I am not very sure if it is related to BPM or ADF, but it looks more like an ADF error..
We have a BPM process with some human tasks. The human tasks pages are ADF pages.
The pages / user tasks are opened properly for a few times, but does not load after that, until we close all the browser windows.
I am getting these errors intermittently whenever I try to open a human task page in the BPM Workspace.
(Common observation is that for the first few times the pages open properly. After more than 3+ times of opening the same task repeatedly, I a getting these 2 errors).
The page stops rendering after the last text '<div' tag.
Following are the 2 exceptions we see in the logs of the server.
We are using MS Sql Server 2008 R2 for database.
I tried with both Type 4 XA and Non XA versions of the JDBC Connections, but still getting the same error messages.
Can anyone please let us know if we might be missing anything.
Thanks for any help.

Hi,
depends on whether you control the BPM task flow or not. If you do, have a look at this thread for how to debug the problem
How to debug "Attempt to validate an already invalid RegionSite"?
Otherwise, post it to the SOA forum if this is initiated by their generated code. The most common reason though is that the task flow lacks a default activity. So if the default activity is somewhat calculated dynamically in your application then this may be a reason

Forcing traffic through load balancer rather than zone to zone

I have several T5140s with 2 LDOMs. Within each LDOM I have multiple zones which contain 2 environments. Each environment comprises the following, an apache instance behind a BigIP load balancer, a JBoss instance, and several misc. The jboss zone has three IP address assigned for multiple applications. Each server is configured identically as far as zone and LDOM layout. We use mod_cluster to cluster our apache and Jboss environment. What I'm trying to accomplish is forcing the apache zone's traffic through the BigIP rather than zone to zone.
Referring to the information below, server2ldom1jboss is one jboss node which needs to connect to both server2ldom1japache and server1ldom1apache. server2ldom1jboss connects to server2ldom1apache via its DNS name which is a NAT address. So webserver2 resolves to 10.10.2.5 which NATs to 10.10.1.5 behind the BigIP. webserver2 responds directly to the jboss zone rather than through the BigIP. Not good. server1ldom1apache works correctly as it's not a local zone.
Referring to this document, https://blogs.oracle.com/solarium/resource/solaris-container-guide-en-v3.1.pdf
section 5.2.7.8
"Connection of zones via external routers using the shared IP instance"
I've created the following routes
route add 10.10.2.5 10.10.1.5
route add 10.10.0.34 10.10.1.5 -interface -reject
route add 10.10.0.35 10.10.1.5 -interface -reject
route add 10.10.0.87 10.10.1.5 -interface -reject
route add 10.10.1.5 10.10.0.87 -interface -reject
route add 10.10.1.5 10.10.0.34 -interface -reject
route add 10.10.1.5 10.10.0.35 -interface -reject
This does prevent the zone to zone traffic, but it also preventing any response. I've tried other options as well, but have not been successful yet. What concerns me is this "These interfaces must not be used elsewhere in the global zone." The 5140 has 4 ethernet ports, which are configured into two port channels. vnet0 and vnet1. The apache instances use vnet1. The remaining zones use vnet0, including the global zone (server2ldom1 10.10.0.21). I think this may be the issue, but do not see an easy resolution without breaking my port channels and losing redundancy and fail-over.
If there is anything I'm missing or a better/different way to do this, I would greatly appreciate any input on this matter.
Thank you.
webserver2 10.10.2.5 NATs to 10.10.1.5
jboss apps 10.10.0.34, 10.10.0.35, 10.10.0.87
10.10.0.0/24 is the lan
10.10.1.0/24 is the network behind the BigIP
10.10.2.0/24 is the webserver network (in front of the BigIP)

After further research, I think the best course of action will be to create a VLAN for the zone behind the BigIP and then create the corresponding interface in the vlan and zone. Using this links as my references in case anyone is interested. I'll post what I come up with.

Data Load taking more than 24 hrs

Hi All,
We are in the process of loading the data from R3 to BW. Its taking more than 24hrs to load 1 yr data. This is because of complexity of ABAP code its taking this much time. We did all the possible ways to improve the performance of the code. But no luck.
In case if the same thing happened in the production system, then how should I forward with the data load as its taking more than 24 hrs for 1 yr data.
I m Planning to load int with out data transfer 1st and then Full load.
Please correct if I m wrong.
Thanks,
RS.

Hi,
where is your ABAP code complexity loacted? in R/3 or in BW?
Are you talking about loading in empty cube taking long time? extraction time?
Analyze the different steps in your monitor and tell us where is the bottleneck;
If you already know the above and you have performed all the tunings (e.g. number range buffereing when filling an empty cube...) then you're correct; init without data and then full loads.
As suggested you could segment your full loads and even run them in paralel...
hope this helps...

Every page I load takes more than a minute to load - clicking anywhere gives message that firefox is not responding. I don't like this version, it sucks - tabs are not defined well, can barely see them.

for instance, if I load www.msnbc.com it will take more than a minute to fully load in that if I click on a link or try to scroll, the entire browser locks up, if I try to scroll, or click on the page, I get the message that the program is not responding.

If you've updated from a version as ancient as 3.5.4, then you run the risk of encountering problems. You should start with a fresh profile to ensure old preferences, data files and changes made by extensions are not interfering.
First, create a backup copy of your profile folder, just to be safe.
* [[Back up and restore information in Firefox profiles]]
Then use the Reset Firefox feature.
* [[Reset Firefox – easily fix most problems]]
If the problem persists, see the following article.
* [[Firefox hangs or is not responding - How to fix]]
Do not reinstall old versions of Firefox. They contain security vulnerabilities and shouldn't be used. Very old versions might also be unable to handle data files in your profile folder in their new formats, which can lead to all sorts of problems. And lastly, many websites require a modern browser to work properly.

Using SQL Loader in more than one table

Hi all,
I have a new question for those who have used SQL Loader. I
have never used it and I just know that I need a control file to
tell SQL Loader what is my flat file layout and what table the
information goes to. My problem is: my flat file has information
that goes to two tables in my schema. Those files are very big
(aprox 280Mb) and I would like to read them just once. Can I do
this with SQL Loader?
Other question, is that the fastest way to import data from
flat files becouse I am using PERL and it takes aprox. 9 hours
to import 10 of those files. I could use UTL_FILE to read it but
I heard that SQL Loader was better.
Thanks for your cooperation

SQL*Loader is the fastest way to load, particularly in direct parallel mode, and can certainly load to multiple tables.
>
My advice would be to have a look at the examples given in the Oracle Utilities guide, there is one for loading to multiple
tables, which I have pasted below.
>
-- Loads EMP records from first 23 characters
-- Creates and loads PROJ records for each PROJNO listed
-- for each employee
LOAD DATA
INFILE ’ulcase5.dat’
BADFILE ’ulcase5.bad’
DISCARDFILE ’ulcase5.dsc’
REPLACE
INTO TABLE emp
(empno POSITION(1:4) INTEGER EXTERNAL,
ename POSITION(6:15) CHAR,
deptno POSITION(17:18) CHAR,
mgr POSITION(20:23) INTEGER EXTERNAL)
INTO TABLE proj
-- PROJ has two columns, both not null: EMPNO and PROJNO
WHEN projno != ’ ’
(empno POSITION(1:4) INTEGER EXTERNAL,
projno POSITION(25:27) INTEGER EXTERNAL) -- 1st proj
INTO TABLE proj
WHEN projno != ’ ’
(empno POSITION(1:4) INTEGER EXTERNAL,
projno POSITION(29:31 INTEGER EXTERNAL) -- 2nd proj
INTO TABLE proj
WHEN projno != ’ ’
(empno POSITION(1:4) INTEGER EXTERNAL,
projno POSITION(33:35) INTEGER EXTERNAL) -- 3rd proj
see the documentation for a complete explanation of the configuration.
Thanks, I will read it.

HP Wireless Officejet 6500 will not stay loaded on more than 1 computer

I have 4 laptops that I have loaded the software on for this printer. We have XP, Vista, and Windows 7 operating systems. I loaded the software first on a windows 7 machine, then the Vista, the other windows 7 and finally the XP machine. It will only print now on the second windows 7 machine. When I try and print from any of the other machines it says the printer is offline and the only way I can get it to print is to reload the software from the disk which then throws the other machine offline. I am extremely frustrated with the machine. If anyone has any suggestions, I would greatly appreciate it as we all need to print!

Tell me about your network - router brand/model, encryption type (WEP, WPA, etc) and ISP type (DSL, Cable, etc).
What security software are you using?
You could try using this utility - it may give some clues.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

Installed new motherboard/cpu; now when I open Adobe XI I get a popup stating I have program loaded on more than one computer and I should input a new code????

Can anyone provide help? Thanks.

This is normal if you change the motherboard or CPU. A lot of software uses the CPU serial number or similar to work out whether this is a new computer install. So just input the code as required.
If this is a volume license, contact your license coordinator.
If this doesn't help please let us know the exact message.

Not able to delete app icons that are in loading stage and more than 20mb, so cant be loaded completely.

I am not able to delete the app icon (loading) of more than 20MB file app.
I have downloaded them to my itunes but they just dont go away even after syncronising.
just to mention i have 3G network but no wifi at present.

Try resetting the iPad. Hold down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple logo appears and see if the loading icon is still there.
If that doesn't work, try deleting the app from the iPad and then sync it again. Delete the app by syncing with iTunes and deselect the app.
While your iPad is connected to your computer and iTunes is running, select your iPad on the left side bar, click on the apps tab in the iTunes window on the right, Uncheck the box next to the name of the app and then sync (click on apply) to remove the app from the iPad. Restart the iPad - hold down on the sleep button until the red slider appears, then slide to shut down, hold the sleep button until the Apple logo appears to start up.
Then connect the iPad to the computer again and go through the same process except this time select the app and click on apply to put it back onto the iPad.
See if that doesn't remove the loading icon.

CSS 11503 Load Balancing Verification

Alright, so I have toiled long and hard to get this right. I think I have the config down but I am unsure on how to verify how this load balancing is working.
Here is the Content Config that I am speaking of:
content cad-rule
    add service wls1-e0
    add service wls1-e1
    add service wls2-e0
    add service wls2-e1
    add service wls3-e0
    add service wls3-e1
    add service wls4-e0
    add service wls4-e1
    add service wls5-e0
    add service wls5-e1
    add service wls6-e0
    add service wls6-e1
    arrowpoint-cookie expiration 00:00:15:00
    advanced-balance arrowpoint-cookie
    redundant-index 2
    vip address 172.30.194.195 range 2
    arrowpoint-cookie name TOQ
    protocol tcp
    port 8001
    url "/*"
    active
Each service in the rule above is configured as follows:
service wls1-e1
port 8001
protocol tcp
strin ags001-e1
ip address 172.30.193.81
keepalive type http
keepalive uri "/cad/index.html"
redundant-index 12
keepalive frequency 20
keepalive maxfailure 10
keepalive retryperiod 2
active
I am using the advanced arrowpoint cookies because I need some stickiness here. Straight round-robin would not have done what I needed it to do.
Now, when I go to my show summary, this is what I see for this rule:
                 cad-rule    Master   wls1-e0 84274
                                            wls1-e1 13144
                                            wls2-e0 96884
                                            wls2-e1 26374
                                            wls3-e0 71145
                                            wls3-e1 16592
                                            wls4-e0 76403
                                            wls4-e1 8657
                                            wls5-e0 118623
                                            wls5-e1 22760
                                            wls6-e0 30836
                                            wls6-e1 20464
The far right column indicates the services hits. I originally had the E1's suspended and activated them later on. So if this was true round robin, all the E0's should have the same number of service hits and all the E1's should have the same number of service hits. But as you can see, the wls5 server is getting hit the most while the wls6 server is sitting there twiddling its thumbs.
Now understanding how the arrowpoint cookies do their load balancing (inserting a cooking into the flow and then timing out after 15 mins as configured above) I would not expect a 1:1 ratio of load balancing between servers. But the distribution above seems rather extreme.
Does anyone have any suggestions on how to both A) verify that this is the right config and B) suggest to my boss that this is working the way it should be working?
Thanks!
James

Hi James,
There are several reasons of the uneven load balancing that you are seeing (based on the show summary). First
of all, the CSS is configured to do stickiness (advance-balance).
With arrowpoint-cookies (for HTTP only) method for stickiness, only the requests coming with the same cookie
are going to get stuck to the same server, since the cookie is
lost when the browser is closed (or based on the expiration), then the stickiness is going to be session
based and if the same client open a new session is going to be load balanced.
Is important to understand that when using stickiness, no real even load balancing is
going to happen since we are sticking new flows to the same server; even when layer 5 stickiness would
permit more even balancing than layer 3 stickiness (source IP based).
Also consider that the "show summary" is a command to see the hits (requests) being balanced to an specific
server, this is a good command to see the load balancing, anyway since the CSS balance
connections (flows), a persistent connection could have a lot of requests, so all those requests are
always going to the same server (incrementing the amount of hits in the counter) while a non-persistent
connection would be just one request (refer to HTTP persistence).
Also keep in mind that if a service is take out for maintenance, or is added to the load balancing later
than another, or if goes down for a period of time, then the CSS will be balancing among the remaining alive
servers. When you add the server again, the another servers are going to have connections
already established, so since the CSS is doing round robin, the server last added will
never have the same amount of connections (nor hits) that the other ones, because while one could
have 55 for example, the new one will have it first connection, and when the first one
gets the 56, the another will get the second, and so on.
Please let me know if this makes any sense.

Load Balancing - Wireless

Hi
If I'm reading correctly Load Balancing is not advisable if using voice of wifi.
On a conroler with 70.220 - Wireless - Advanced - Load balancing
Load balancing - client windows is default 5, max denial 3
But on the wlan, the load balancing isn't enabled..
Which one is the master setting?
We're boardcasting several SSIDs, one of them is a guest SSID, which is open, so we get the Apple devices autmaticaly associating to them.
So if we dont set the load balancing on each wlan, this means there is a msximum of 5 devices to 1 AP, doesn't matter which wlan it's on?
Is there a best practice guide for load balancing?
Clarrifaction would be great
Cheers
Craig

Craig,
Do not use load balancing for latency-sensitive WLANs, especially voice WLANs. Rejecting voice clients extends their roaming delay and can drop calls.
The setting on the WLAN Advanced tab determines whether or not clients associating to that WLAN will be denied if the load balancing algorithm determines the AP to which the client wants to associate is too loaded (determined by the global LB settings). If you have the box unchecked, then LB is not in effect for that WLAN and clients on that WLAN will never be rejected.
The load balancing algorithm is run against clients for an AP. The count of clients is cumulative for all WLANs, i.e., the load balancing numbers are not set and comared on a per-WLAN basis. This wouldn't make a lot of sense as the LB algorithm is attempting to keep clients physically spread across infrastructure radio resources, regardless of whether you have 1 WLAN or 5 WLANs active on the radio.
I don't know of a best practices guidefor load balancing other than don't use it on WLANs that have low-latency applications such as voice or live-streaming (unbuffered) video. The controller configuration guide is a good place to start and does a pretty good job of explaining how it works.
One other thing I would recommend is to make the algorithm less aggressive. I think max 3 denials is too high and would drop to 1 or 2. I'd also open up the LB window size to about 8 or 10 instead of the default 5.
I think some folks on the forums here have found some issues with LB, although I haven't run into too many so far. I think the AP sends a message type 17 and some clients have trouble processing it (or something like that). You might want to search the forums here and check the bug toolkit to see if there's anything that comes up.
