NNM iSPI Performance for Traffic silentInstall*.properties missing for Linux

HP -- I've been trying to figure out a way to get this information to you, and this is the best I could find. When performing a silent installation of HP NNM iSPI Performance for Traffic, you need the silentInstallExt.properties, silentInstallMaster.properties, and silentInstallLeaf.properties files. These files are not supplied with the Linux installation DVD image (Software_NNM_iSPI_Perf_Traf_Linux_9.20_Eng_TB770-15009.iso) -- you might want to remedy that. If anyone needs to find the files for a silent install on Linux, you can get them from the Windows installation DVD image (Software_NNM_iSPI_Perf_Traf_10.00_Win_TB770-15014.iso) in the Traffic_NNM_Extension, Traffic_Master, and Traffic_Leaf directories.

Slow TCP performance for traffic routed by ACE module

Hi,
the customer uses two ACE20 modules in active-standby mode. The ACE load-balances servers correctly. But there is a problem with communication between servers in the different ACE contexts. When the customer uses FTP from one server in one context to the other server in other context the throughput through ACE is about 23 Mbps. It is routed traffic in ACE:-( See:

There is parameter map configured with rebalance persistant for cookie insertion in the context.
Do you know how can I increase performance for TCP traffic which is not load-balanced, but routed by ACE? Thank you very much.

Default inactivity timeouts used by ACE are
icmp 2sec
tcp 3600sec
udp 120sec
With your config you will change inactivity for every protocol to 7500sec.If you want to change TCP timeout to 7500sec and keep the
other inactivity timeouts as they are now use following
parameter-map type connection GLOBAL-TCP
set timeout inactivity 600
parameter-map type connection GLOBAL-UDP
set timeout inactivity 120
parameter-map type connection GLOBAL-ICMP
set timeout inactivity 2
class-map match-all ALL-TCP
match port tcp any
class-map match-all ALL-UDP
match port tcp any
class-map match-all ALL-ICMP
match port tcp any
policy-map multi-match TIMEOUTS
class ALL-TCP
connection advanced GLOBAL-TCP
class ALL-UDP
connection advanced GLOBAL-UDP
class ALL-TCP
connection advanced GLOBAL-ICMP
and apply service-policy TIMEOUTS globally

RDS Gateway 2012, RemoteApp Displays "A Revocation check could not be performed for the Certificate" via RDWEB

I have searched through the forums and there are a number of posts that are similar but all the checks they list seem to not apply to this one.
My current setup is as follows
All Servers are 2012 R2
1 x DC server
1 x RDS Gateway server with RDS Web installed
1 x Session Host Server
Certificate supplied by godaddy with 5 names. (included is the name of the RDS Gateway/Web server in the certificate, the internal name of the session host server is not included as the internal names are differnet to the external)
My tests are as follows
Navigating to the RDSWEB page from a machine inside the same network (windows 7 sp1) but not on the same domain is fine no errors and logging in and launching any published application is fine with no errors.
However logging in on another machine that is external from the network (windows 7 sp1) is ok up to the point of launching any of the published apps I get the error about ""A Revocation check could not be performed for the Certificate". this
prompts twice but does allow you to continue and login and use the app till the next time. If I view the certificate from the warning message all appears to be ok with all certs in the chain.
I have imported the root and intermediate certs to each of the gateway/rdsweb server and session host server into the computer cert store just to be on the safe side. This has not helped, I have also run the following command from both windows 7 machines
with no errors on either
certutil -f –urlfetch -verify c:\export.cer
I cant seem to see where this is failing and I am beginning to think there is something wrong with godaddy cert itself somehow.
If I skip rdsweb and just use MSTSC with the gateway server settings then I can login to any machine on the network with no errors so this is only related to launching published apps on the 2012 R2 RDWEB or session host servers.
Any help appreciated

Hi,
1. Please make sure the client PCs have mstsc.exe (6.3.9600) installed.
2. If you are seeing a name mismatch error, you can set the published name via this cmdlet:
Change published FQDN for Server 2012 or 2012 R2 RDS Deployment
http://gallery.technet.microsoft.com/Change-published-FQDN-for-2a029b80
To be clear, the above cmdlet changes the name that shows up next to Remote computer on the prompt you see when launching a RemoteApp. You should have a DNS A record on your internal network pointing to the private ip address of your RDCB server.
Additionally, in RD Gateway Manager, Properties of your RD RAP, Network Resource tab, you should select Allow users to connect to any network resource or if you choose to use RD Gateway Managed group you will need to add all of the appropriate names to the
group.
For example, when launching a RemoteApp you would see something like Remote computer: rdcb.domain.com and Gateway server: gateway.domain.com . Both of these names need to be on your GoDaddy certificate.
Please verify the above and reply back so that we may assist you further if needed. It is possible you have an issue with the revocation check but I would like you to make sure that the above is in place first.
Thanks.
-TP
Thanks for the response.
To be clear I am only seeing a name mismatch and revocation error if I assign a self signed cert to the session host as advised earlier in the thread by "Dharmesh Solanki", if I remove this and assign the 3rd party certificate I then
just get the revocation error , I have already ran the powershell to change the FQDN's but this has not resolved the issue although the RDP connection details now match the external url for RDWEB when looking at one of the remoteapp files. The workspace
ID still shows an internal name though inside this same file.
RD Gateway is already set to connect any resource, when connecting using remote app both names (RDCB/RDGateway) show as being correct and are contained within the same UCC certificate. I also already have a DNS entry for the Connection broker pointing to
the internal ip.
Do you know if the I need the internal name of the session host servers contained within the same UCC certificate seeing as they are different fqdn's than what I am using for external access ? I resigned the UCC certificate and included the internal name
of the session host server to see if this would help but for some reason I am still seeing the revocation error. I will check on a windows 8 client pc this evening to see if this gets any further as the majority of the testing has been done on windows 7 sp1
client pc's
Thanks

Performance Pack for Linux

Hi all,
I am trying to install Weblogic 4.5.1 on Red Hat Linux 6.1
When I set the weblogic.system.nativeIO.enable to true within the
weblogic.properties file, I receive an exception:
java.lang.UnsatisfiedLinkError: no muxer in shared library path
(libmuxer.so)
I tried looking through the installation documentation and was unable to
find anything related specifically to using the performance pack under Linux
(there was information specific to AIX and Solaris, however).
So I guess my question is: Is the performance pack supported for Linux? If
so, what might I have to modify in order for it to work correctly? Thanks-

It should be available in the Denali (5.1) release of WLS or shortly
thereafter. Denali is GA at the end of March.

We were hoping that this was the

Any help would be appreciated!

Performance for table BKFP

Hi,
I would like to enquire is there anyway that i can improve the performance for table BKPF from the ABAP code point of view.
Because we have customise one program to generate report for the asset master listing.
one of the select statement are show as below:
      SELECT SINGLE * FROM BKPF WHERE BUKRS = ANEP-BUKRS
                                  AND GJAHR = ANEP-GJAHR
                                  AND AWKEY = AWKEYUS.
I would like to know how it different from the select statemene below:
SELECT SINGLE * FROM BKPF INTO CORRESPONDING FIELDS OF T_BKPF
      WHERE
      BUKRS = ANEP-BUKRS
AND GJAHR = ANEP-GJAHR
AND AWKEY = AWKEY.
Which of the select statements above can enhance report,because currently we have face quite bad issue on this report.
Can i post the ABAP code on this forum.
Hope someone can help me on this. thank you.

Hi,
As much as possible use the primary keys of BKPF which is BUKRS, BELNR and GJAHR. Also, select only the records which are needed so to increase performance. Please look at the code below:

FIELD-SYMBOLS: <fs_final> LIKE LINE OF it_final.
LOOP AT it_final ASSIGNING <fs_final>.
get records from BKPF
    SELECT SINGLE bukrs belnr gjahr budat bldat xblnr bktxt FROM bkpf
    INTO (bkpf-bukrs, bkpf-belnr, bkpf-gjahr, <fs_final>-budat,
          <fs_final>-bldat, <fs_final>-xblnr, <fs_final>-bktxt)
    WHERE bukrs = <fs_final>-bukrs
      AND belnr = <fs_final>-belnr

by negative 1
    IF <fs_final>-shkzg = 'H'.
      <fs_final>-dmbtr = <fs_final>-dmbtr * -1.
    ENDIF.
combine company code(bukrs), accounting document number(belnr),
fiscal year(gjahr) and line item(buzei) to get long text.

Please give me suggession for improving performance for the programmes.

hi,
you try like this
DATA:BEGIN OF itab1 OCCURS 0,
     vbeln LIKE vbak-vbeln,
     END OF itab1.
DATA: BEGIN OF itab2 OCCURS 0,
      vbeln LIKE vbap-vbeln,
      posnr LIKE vbap-posnr,
      matnr LIKE vbap-matnr,
      END OF itab2.
DATA: BEGIN OF itab3 OCCURS 0,
      vbeln TYPE vbeln_va,
      posnr TYPE posnr_va,
      matnr TYPE matnr,
      END OF itab3.
SELECT-OPTIONS: s_vbeln FOR vbak-vbeln.
START-OF-SELECTION.
SELECT vbeln FROM vbak INTO TABLE itab1
WHERE vbeln IN s_vbeln.
IF itab1[] IS NOT INITIAL.
    SELECT vbeln posnr matnr FROM vbap INTO TABLE itab2
    FOR ALL ENTRIES IN itab1
    WHERE vbeln = itab1-vbeln.
ENDIF.

Estimating range of performance for a query

I wonder if this is an intractable problem:
Using information available from the data dictionary and from the tables referenced in a query, estimate actual minimum and maximum run times for a given query, predict performance for various combinations of realistic values for the variables that influence performance.
Variables would include:
what kinds of IO are used
how much of each type of IO is used
atpr - average time per read for various types of IO
data relationships - min/max/avg #child records per parent record
server caching - how many gets require IO
clustering factor of indexes
I think a related item would be client caching
continued rows - how many per N primary rows
Type of plan - initally I think perhaps all NL and all hash joins are simple starting points
Some of the variables are observable from target systems ( atpr, data relationships, clustering factor, .. ).
I know, the optimizer already does this.
I know, it's faster to just run test queries.
Repeated work with such ideas would cause refinement of the method and
eventually might result in reasonably accurate estimates and improved understanding
of the variables involved in query performance, the latter being more important
than the former.
Please tell me why this is a bad or good idea. I already mentioned a couple of counter-arguments above,
please don't bother elaborating on them unless you're shedding light and not flaming. I think this would be
somewhat like the index evaluation methods in Lahdenmaki/Leach's book, but more Oracle-centric.
Or maybe I'm kidding myself..

Could you possibly invert the problem a bit and use some statistical process control techniques to set some baselines and to identify statements that are moving outside of their control limits?
For example, a control chart could be built for each SQL statement based on actual execution performance data in the AWR-- you just need to know the average and the standard deviation execution time for that which should be relatively easy to derive. You can then gather the performance data for every snapshot interval, add a new data point to the chart. There are a number of different sets of rules for determining a "signal" from this data as opposed to normal random variation. That would generally be a reasonable way for everyone to agree on what performance should really be expected for a SQL statement and it would be a good early warning system that "something has changed" when you see a particular query start to run consistently slower (or faster) than it had been. That, in turn, might lead to better discussions, i.e. "sql_id Y is starting to run more slowly than we were expecting based on prior testing because we just introduced Process X that is generating a pile of I/O in the same window your query runs in. We can adjust Y's baseline to incorporate this new reality. Or we can move when Y runs so that it isn't competing with X. Or we can try to optimize Y further. Or we can get the folks that own X and Y into a room and determine how to meet everyone's requirements". Particularly if your performance testing can identify issues in test before the new Process X code goes into prod.
JustinThose are interesting ideas. Better discussions would be a good thing.
Re inverting the problem from prediction to reaction:
I have done some work with the script at http://kerryosborne.oracle-guy.com/2008/10/unstable-plans/ which of course work only for as much AWR data as you keep. I've had mixed results. I haven't tried to set it up to alert me about problems or to monitor a specific set of sql_ids. I've found it to be useful when users/developers are complaining about general slowness but won't give you any useful details about what is slow.
Here are a few complicating factors re identifying significant divergences in query performance or resource use - There are queries that accept different inputs that rightly generate completely different workloads for the same query, e.g., a product/location/time query whose inputs allow wide variations in the selectivity for each of the dimensions. There are applications that never heard of a bind variable, and there are queries that rightly do not use bind variables ( yes, even in the age of sql injection ).
In general , aside from the usual Grid Control and Nagios alerts re CPU/Memory/IO thresholds, and some blocking-locks alert programs, it's up to our users/developers to report performance problems.
Re my original question - I'll admit I was pretty sleep deprived when I wrote it. Sleep deprivation isn't usually conducive to clear thinking, so it will be interesting to see how this all looks in a month. Still, given that so much testing is affected by previous test runs ( caching ), I thought it made sense to try to understand the worst-performing case for a given execution plan. It's not a good thing to find that the big query that was tested to death and gave users a certain expectation of run time runs in production on a system where the caches have been dominated for the last N hours by completely unrelated workloads, and that when the query runs every single block must be read from a spindle, giving the users a much slower query than was seen in test.
Maybe the best way to predict worst-case performance is to work from the v$ metrics from test, manipulating the metrics to simulate different amounts of caching and different IO rates, thus generating different estimates for run-time.

Technical Performance for new PC: RAM

I need a new PC and have a quad core. By now I have 8 RAM but it seems sometime slowwhen working on a series of 300-800 photos
What would be the effect of 16 RAM with the new 4. generation PCs quad core 4x 2,0 GH
Thanks

Hallo,
I have no specific step in mind, but always when you need to render and change format / size (2:1)

Traffic lights are missing on Safari

Traffic lights are missing on Safari. Please help.

To regain your 'traffic lights' go to top of screen and minimise, then drag the screen to the required size. Every time I maximised the lights disappeared, but when I minimised it they showed up. I eventually caught on and then dragged the minimised screen to the required size, Easy when you know how!!

Standard Report check whether Goods Issue has been performed for DN

Hi All,
My users is having a list of DNs where they would like to check if Post Goods Issue has been performed for them. I would like to ask is there any standard reports as to check if a Delivery Note has PGI performed?
I have tried report VL06G but in this report we cannot give the DN No. as the key.
Thanks.

There is no standard reports to check GI by DN number.
You have to find out the Outbound Number first then check by Outbound number.
In SE16N, key VBFA table
Pump in your DN number under "Follow-on doc."
Under "Prec.doc.categ." select "J".
with the outboud number, you can proceed to check using above report suggested.
Alternatively, using same VBFA table. Pump in list of outbound number under "Preceding Doc." and select "Subs.doc.categ." as "R".
If you can set-up query reports, you can also get all the information directly with the DN Numbers.

Hi,
You can use Performance Monitor and add the required counters.
Check the below Technet article on Performance Monitor.
http://technet.microsoft.com/en-us/library/cc749249.aspx
Below are the steps to monitor the process in Performance Monitor.
- Go to the Performance Monitor.
- Right-click on the graph and select "Add Counters".
- In the "Available counters" list, open the "Process" section by clicking on the down arrow next to it. Select "% Processor Time" (and any other counter you want).
- In the "Instances of selected object" list, select the process you want to track. Then click on "Add >>" button. Click on OK.

How to improve the performance for integrating third party search engine

hi,
I have been working on integrating verity search engine with KM. the performance for retrieving search result totally depend on how many search result returned, for example if there is less than 10 records, it only takes 3 seconds, but if there are 200 records, it takes about 3 minutes, is it normal? anyway to improve it? Thanks!
T.J.

Thilo,
thanks for the response, would you recommend some document for configuring KM cache service, I did change memory cache, and also dynamic web reposity, whatelse out there that I can change? right now, I have one instance(EP6.4 sp11) works well, it returns 200 records from Stellent within 6s. But when I put this KM global service on EP6.0 sp2 (our current system) it takes about 15s. I am not sure is this because of different EP version, or something else. I have tried my best to slim down SOAP component from Stellent. I don't think anything else can be done from that side anymore. before I changed the SOAP, it tooks about 60s. just wonder what else I can do on KM side to improve it performance? Thanks!
T.J.
