Cisco ASR 1002- performance issue due to access list

Hi,
We are planning to implement inbound access-list to block subnets from particular country. Since the subnets are not contiguous, we have about 16000 lines of acl entries.
I want to know, would there be any performance or latency issues after applying 16k lines of acl?
Is there a good document where I can read more about ACL limitations and performance issues on ASR.
This is for ASR1002, running IOS-XE 15.3(1)S1.
Thanks

Cisco ASR 1002

Does the router Cisco ASR 1002 support ESP module of 10GB?
if not what is the limit ?

Hi hendrikus1982, the ASR 1002 can only support the 5GB built in ESP it does not support the module for 10GB. Can I ask what you are planning to do maybe i can provide you with an alternative. please feel free to email me directly at [email protected] hope this helps!

Cisco ASA 5505 performance issues on downloads - data into the ASA from the Internet

I have having serious issues with performance on my ASA 5505s that I am testing with 9.2.3 code.
I stripped the config and removed as much stuff as I could - no VPN etc. and I am ONLY getting about 30-40Mbps downloads from sites but 95Mbps uploads???? Anyone else seeing these problems? If I remove the firewall my PC can hit 300/300Mbps to the same sites using the same switch and cable.
I installed 1Gb of mem on the ASA 5505 but it made no difference. The ASA has a UL IP Security license but I am only using and inside and outside address for these tests, no other ports configured.
Is anyone else seeing this performance problem with the 9.2.3 code? I went to this from 8.2.5 to try to resolve QOS failure bugs that I found in the 8.2.5 code. I did not expect to have a performance hit though and it is only on downloads TO the ASA from the Internet from all speed test sites that I try. Uploading speeds seem fine. No access-lists on my interfaces either...barebones config.
My FIOS and switch interfaces are fine...no errors on any interfaces and the same switch interface hits 300/300Mbps when my laptop is directly attached.
Anyone have a barebones config on their ASA 5505 that flies...I will try it on mine and see if some command somewhere (hidden) is causing the issue. I even cleared the config and started with a clean slate just in case I was missing some command from the older configs that may have impacted performance.

After changing the switch with a high end switch my performance increased but I am still not happy with the throughput out of my ASA. I have about 50+ ASAs 5505s and a dozen 5510s. Most remote sites have 5505s. All my sites right now have 8.2.5-51 and I wanted to put 9.2.3 out there to solve issues I have uncovered on the 8.2.5 code with regards to QOS issues.
I get much better results using the Cisco 3750X attached to the FIOS (right around 300/300 with my laptop directly attached to the 3750x bypassing the ASA - my FIOS circuit rating is also 300/300). Going through the ASA to the same test site I get download speeds of 35 to 75. Changes randomly which really bothers me. My uploads speeds are ALWAYS faster then my download speeds. Example - best download I would ever get is 75Mb and my upload would usually hit 95Mb during the same test period.
I may have to live with it but the inconsistency is what really bothers me.
Here is the config I am currently using. Nothing going on during testing since only a single PC is attached. VPN tunnel to the main site can be up or down...doesn't seem to make any difference. PC does to site directly from outside interface of ASA...split tunneling. Even when I removed tunnels and tested with just the ASA as a firewall to the Internet I was still seeing the same inconsistencies.
Anything obviously missing - new command or anything? Xlates causing issues?

Performance issues of SQL access to AW

Hi Experts:
I wonder whether there is performance issues when using SQL to access AW. When using SQL to access cubes in AW, the SQL queries the relational views for AW objects. And the views are based on OLAP_TABLE function. We know that, views based on any table function are not able to make use of index. That is to query a subset of the data of a view, we would have to full scan the view and then apply the filter. Such query plan always lead to bad performance.
I want to know, when I use SQL to retrieve a small part of data in an AW-cube, will Oracle OLAP engine retrieve all data in the cube and then apply the filter? If the Oracle OLAP engine only retrieves data needed from AW, how can she did it?
Thanks.

For most requests the OLAP_TABLE function can reduce the amount of data it produces by examining the rowsource tree , or WHERE clause. The data in Oracle OLAP is highly indexed. There are steps a user can take to optimize the index use. Specifically, pin down the dimension(s) defined in the OLAP_TABLE function LIMITMAP via (NOT)IN lists on the dimension, parent, level or GID columns. Use of valuesets for the INHIER object, instead of a boolean object.
In 10g, WHERE clauses like SALES > 50 are also processed prior to sending data out.
For large requests (thousands of rows) performance can be a problem because the data is being sent through the object layer. In 10 this can be ameliorated by wrapping the OLAP_TABLE function call with a SQL MODEL clause. The SQL MODEL knows a bit more about the Olap options and does not require use to pipe the data through the object layer.
SQL MODEL example (note no ADT defintion, using of auto ADT) This can be wrapped in a CREATE VIEW statement :
select * from olap_table('myaw duration session', null, null, 'measure sales as number from aw_sales_obj dimension d1 as varchar2(10) from geog ...rest of dimensions')
sql model dimension by (d1, d2, d3, d4) measures (sales, any attributes, parent columns etc...) unique single reference rules update sequential order ()
Example of WHERE clause with above select.
SELECT *
FROM (select * from olap_table('myaw duration session', null, null, 'measure sales as number from aw_sales_obj dimension d1 as varchar2(10) from geog ...rest of dimensions')
sql model dimension by (d1, d2, d3, d4) measures (sales, any attributes, parent columns etc...) unique single reference rules update sequential order ()))
WHERE GEOG NOT IN ('USA', 'CANADA')
and GEOG_GID = 1
and TIME_PARENT IN ('2004')
and CHANNEL = 'CATALOG'
and SALES > 50000;

Performance issue in guest access anchored in DMZ

Hello,
I've been having performance issue in our wifi guest network anchored in the DMZ.
I have 3-5508 anchor controllers behind the Checkpoint gaia firewall and have 24 guest SSIDs in here.
Right now, only 14 guest SSIDs are enabled and tunnelled out in this anchor DMZ setup, whenever I try to add few more SSIDs I run into performance issue.
It seems to me that the problem is not about these additional SSIDs that I add because the performance issue starts to appear only when the traffic peaks or associated clients reached to certain number which is in my case 4000 users.
The firewall serves as the NAT device and gateway for all these guest SSIDs. The cpu, memory, number of connections have been checked and verified low.
Has anyone seen a problem like this? or has a setup like mine?
thanks!

Presuming you're not exceeding client count maximums on the individual WLCs I can't say I've seen anything in line with this "specific problem", but anything is possible.
What are the specific "performance issues" the clients are experiencing? Is it just general poor performance (slow web browsing/etc) or do you see other issues like no internet connectivity at all or something else?
May I ask, what is the use-case behind having 24 SSIDs on your anchors?

Monitoring Cisco ASR 1002 with IOS-XE in IPM 4.2

We are running LMS 3.2 with IPM 4.2 installed....and we are looking to do IPSLA monitoring on a couple of our Cisco ASR's with IOS-XE code installed.
I looked at the IPSLA feature mapping and it only talks about supported IOS code....do we need to upgrade our current IPM module to a current version?

Hi Konstantin,
Regarding "It is strange that these commands cleaned from sh run view.": this is normal for many default configuration commands.
Mine is a lab device so I cannot really comment on stability or provide you a recommendation based on that. However, I see that the download section from Cisco.com mentiones the following release as the recommended based on quality, stability and longevity:
asr1002x-universal.03.07.04a.S.152-4.S4a.SPA.bin
The best would be for you to check this with yor cisco Account Team or Advanced Services Team as normally they are the proper point of contacts for SW advisory.
Regards.

Avoiding performance issue due to loop within loop on internal tables

Hi Experts,
I have a requirement where in i want to check whether each of the programs stored in one internal table are called from any of the programs stored in another internal table. In this case i am looping on two internal tables (Loop within a loop) which is causing a major performance issue. Program is running very very slow.
Can any one advise how to resolve this performance issue so that program runs faster.
Thanks in advance.
Regards,
Chetan.

Forget the parallel cursur stuff, it is much to complicated for general usage and helps nearly nothing. I will publish a blog in the next days where this is shown in detail.
Loop on loop is no problem if the inner table is a hashed or sorted table.
If it must be a standard table, then you must make a bit more effort and faciliate a binary search (read binary search / loop from index exit)
see here the exact coding Measurements on internal tables: Reads and Loops:
/people/siegfried.boes/blog/2007/09/12/runtimes-of-reads-and-loops-on-internal-tables
And don't forget, the other table must not be sorted, the loop reaches anyway every line. The parallel cursor requires both tables to be sorted. The additional sort
consumes nearly the whole advantage of the parallel cursor compared to the simple but good loop in loop solutions.

SAP MaxDB 7.7.07.16 - performance issue due to IOWait(R) task

We are running MaxDB 7.7.07.16 unicode in a non SAP environment (is basis for a web application).
Database Server has 4 Cpu's, 8 Gb RAM, operating system Debian-Linux 6.0.
We have some performance problems in not regular periods of time.
The performance problem occurs for a time frame between 3 and 15 minutes and blocks more or less the complete system.
After a long phase of checking and evaluating possible issues, we think that we are very near to the issue.
We identified the database tasks
- TblPrfC - Prefetch Table Coordinator:
- PrefPag - Prefetch Pages
having the current state "IO Wait (R)".
As long these tasks are in state "IO Wait (R)" the users (at the web application) gets awful slow respond times on their queries.
On 9th of April 2011 we changed the DB parameters:
- ReadAheadTableThreshold old 0 => new 128
But today we got the same performance problem again.
If you have any hints or tips, you're welcome!
Best regards
Hannes

Hello Hannes,
ok brief but hopefully usefull answer to your post:
- if the database I/O generated by SQL statements alone brings the system to a grinding halt, then your storage system is undersized. How should it be able to handle additional I/O, e.g. for backups if it isn't capable to handle the standard I/O?
- the prefetching tasks are used to speed up large scan operations. So, the next thing to do here is to find statements that perform table scans and check whether or not these can be tuned to KEY or Index accesses
- As a workaround, I would propose to increase the value of ReadAheadTableThreshold to, say, 500, so that the prefetching is done only for really large scans.

Lars

Performance issue due to column formula and filters

Hi,
I am facing strange issue with performance for my OBIEE reports. I have two sets of reports Static and Dynamic. Both runs against same tables. The only difference between these reports is that the Static reports would run against all the data for given aggregation level e.g. Year, Month, Date and so on. Where as for Dynamic one I have range prompts to filter data. Other difference is that I have a column formula for one of the column in the Dynamic report, which is nothing but Go URL to show another page with certain parameters.
The static report takes around 14-15 Seconds where as the Dynamic one takes around 3.5 min. The amount of data and range is same here. From the logs I could see that for the Static reports, i.e. reports without filters it applys group by at SQL level where as it is not doing so for the dynamic one. Is this expected ?
Second issue is, even if I say remove the filters and just have report with column formula in one and no formula in other there is significant time difference in the processing at Presentation service layer. Again this is taken from the log. it takes 8 second to get data from DB but shows almost 218 Seconds as response time at Presentation layer.
Below are conceptual details about table and reports -
Table 1 (It is date dimension) : Date_Dim
DateCode Date
Day Number
MonthCode Varchar2
YearCode Varchar2
Table 2 (It is aggregate table at year level) : Year_Aggr
DateCode Date (FK to Table1 above)
Measure1
Measure2
Measure3
Measure4
Measure5
Report 1
Date_Dim.YearCode | Year_Aggr.Measure1 | Year_Aggr.Measure2 | Year_Aggr.Measure3 | Year_Aggr.Measure4
Report 2
Dashboard Filter : Dimension1 | Dimension2 | Year Start | Year End |
Date_Dim.YearCode | Year_Aggr.Measure1 | Year_Aggr.Measure2 | Year_Aggr.Measure3 | Year_Aggr.Measure4
Column formula for Date_Dim.YearCode is something like :
'<a href="saw.dll?Dashboard&PortalPath=somepath and parameters target=_self>' || Date Dim"."YearCode" || '</a">'
Filters :
Dimension1 is prompted...
Dimension2 is prompted...
cast("Date Dim"."YearCode" as Int) is greater than or equal to @{Start_Year}
cast("Date Dim"."YearCode" as Int) is greater than or equal to @{End_Year}
Note : I need to apply cast to int as column is varchar2, legacy problem.+
How can I fix this? Am I missing something? In the result of report2 the DB SQL doesn't show the year in where thought it is displayed in the logical sql.
Let me know if anybody had faced this and have fixed. Or suggetion to make changes to fix this.
Thannks,
Ritesh</a>

Hi Ritesh,
I think you right about the root cause of your problem. The first request does the group by in the database which returns fewer records to the BI Server for processing. The second request does not do the group by and sends significantly more records back to the BI server forcing it to do the group by. Compound that with the fact that pivot table views are relatively expensive computationally and that explains the difference between the execution times.
Assuming that the execution time of the first report is satisfactory, I would recommend you try to experiment with a few settings to see if you can get the second report to do the group by in the database.
Are the two filters identical except for the following conditions?
cast("Date Dim"."YearCode" as Int) is greater than or equal to @{Start_Year}
cast("Date Dim"."YearCode" as Int) is greater than or equal to @{End_Year}
Best regards,

Performance issue due to RFC calls. (R/3 to R/3 system)

Hi,
My application face serious performance problem because of RFC calls (R/3 system to R/3 system).
1)is there any transaction code for doing performance analysis on RFC calls in R/3 system?
2)How far large volume of Data Transfer (mainly due to internal tables) in a RFC call affects the performance? is there any limit for data transfer size at a time in a RFC call? if so how to calculate for best performance?
Thanks and regards,
Prakash.

Hi Andreas,
Suppose an RFC enabled Fm having an internal table as importing parameter.During execution of this Fm with 4000 enteries for the internal table results in performance degrading.is there any way to improve the performance?.
Thanks and regards,
Prakash.

Performance issue due to localization code in SSRS 2008

The reports I am working on consist lot of data and all the customers use it frequently.
Report title and columns are localized by expressions .
This takes long time for report rendering and exporting to csv. When I test without the localization code it doesn't take that long .
Can someone help me to optimize the report. SSRS 2008 R2
Archana

Hi Archana,
In Reporting Services, the total time to generate a reporting server report (RDL) can be divided into 3 elements:
Total time = (TimeDataRetrieval) + (TimeProcessing) + (TimeRendering)
TimeRendering means the number of milliseconds spent after the Rendering Object Model is exposed to the rendering extension. It includes the Time spent in on-demand expression evaluations (e.g. TextBox.Value, Style.*). So it is make sense that the report
with localization code takes longer time.
Besides, we can improve the report performance form other aspects. For example, we can add filter, sorting and aggregation in dataset query, because filter, sort, and aggregation is more efficient on the data source than during report processing. For more
details about report performance, please refer to the following article:
http://technet.microsoft.com/en-us/library/bb522806(v=sql.105).aspx
If there are any other questions, please feel free to ask.
Thanks,

System performance issue due to multiple submission of a job

For month end recoincilation users run few critical reports which are quite resource consuming.
In order to control this, want to restrict the usage of such reports. For example if one session is active (Foreground or background) user couldn't submit another job or gets a pop up with an error mesage.
Searched SDN for this and couldn't find much.
anya

Anya since this is the ABAP forum and I happen to be an ABAP programmer I can give you an ABAP solution. This would involve changes to the code in all these reports so you would need the help of an ABAP programmer if you are not one.
a) Create a Z table containing 3 fields
1) Client of type MANDT (Primary key field)
2)Program Name of type PROGRAM_ID (Primary key field)
3) User name of type XUBNAME (Regular field).
b) Create table maintenance for this internal table.
c) Create one record for each of the programs you want to regulate. You only need to enter the program name initially and leave the user name blank.
d) In all the ABAP programs make the following change.
1) Under the START-OF-SELECTION event of the report lock the use function module ENQUEUE_E_TABLEE to lock the record in the Ztable for the program being executed. Look at the sample code below.
TABLES: <ztable>.
data: w_message(100) TYPE c,
        w_locked(1) TYPE c.
CALL FUNCTION 'ENQUEUE_E_TABLEE'
EXPORTING
    tabname              = <ztable name>
    varkey               = <concatenation of mandt and sy-cprog>
EXCEPTIONS
   foreign_lock         = 1
   system_failure       = 2
   OTHERS               = 3.
IF sy-subrc EQ 1.
SELECT SINGLE *
    FROM <ztable>
    INTO <ztable>
    WHERE program FIELD name EQ sy-cprog.
IF sy-subrc EQ 0.
    CONCATENATE 'Program'
                sy-cprog
                'is currently being used by'
                <ztable>-<user name>
      INTO w_message SEPARATED BY space.
    MESSAGE e208(00) WITH w_message.
ENDIF.
ELSEIF sy-subrc EQ 0.
w_locked = 'X'.
SELECT SINGLE *
    FROM <ztable>
    INTO <ztable>
    WHERE program FIELD name EQ sy-cprog.
IF sy-subrc EQ 0.
    <ztable>-user name> = sy-uname.
    MODIFY <ztable> FROM <ztable>.
ENDIF.
ENDIF.
e) At the event END-OF-SELECTION (at the end of the program) use function module DEQUEUE_E_TABLEE to unlock the record. Look at sample code below.
CASE w_locked.
WHEN 'X'.
    CALL FUNCTION 'DEQUEUE_E_TABLEE'
      EXPORTING
        tabname          = <ztable name>
        varkey             = <concatenation of mandt and sy-cprog>.
ENDCASE.
This code is designed to allow just one user or job to run the program at a time. The second person will be issued an error message informing him/her that the program is being used by <user name>.

Performance Issues due to Loading of ADF/JClient View Objects

Hi,
I developed a two-tier ADF/JClient application.
When the ADF/JClient application opens for the first time, there's a big delay
However opening it subsequently, takes less than half of the time to open the screen.
I think it might the xml files of different view objects which the framework loads for the first time, and thus takes a lot of time. And after that, the time to open the application reduces.
We have around 200 view objects in our application. Can this be the reason?
If yes, then can we load the view objects before ahead, or can we just load them at the very time they are requested ?
Thanks,
Makrand Pare

Hi Makrand,

"Limiting Fetching of Business Components Attributes in ADF Swing
http://www.oracle.com/webapps/online-help/jdeveloper/10.1.3/state/content/navId.4/navSetId._/vtTopicFile.developing_jclient_applications%7Cjui_plimitingfetching%7Ehtml/
Note: In local mode deployment (the client and Business Components reside in the same VM), the fetching of attribute properties is not supported.
You can optimize startup time for a Business Components client application and the remotely deployed Business Components by specifying the list of view object attributes that your client uses. If you create a project without the metadata, by coding to the API, you will want to add fetchAttributeProperties() to the bootstrap code of the client forms with a list of only the attributes used by the form. Without this method call, your client form would fetch all control hint properties (including the attributes format and label for example) for all the attributes of the named view objects in the application module, in a single network roundtrip.
For example, when you do not intend to use all the attributes of the ADF Swing form's bound view object, with the fetchAttributeProperties() method, your ADF Swing form fetches only the information required to layout your forms, while ignoring the attributes you do not require.
Note: In local mode deployment (the client and Business Components reside in the same VM), the fetching of attribute pro
Calling fetchAttributeProperties() will prevent property methods such as getFormat() or getLabel() from being called on the Business Components attribute definition whenever the form is created."

ASR 1002

Hello all,
I have 1 Cisco ASR 1002 configured as a normal edge router connecting to ISP.
When i used ftp service from PC outside to servers inside, the FTP service ran normally in the morning but it is slower by afternoon and till the end of the working day, client PC couldn't work anymore
So, i restarted ASR 1002 and it did work well again
The next day, i replaced ASR 1002 with Cisco router 2801, configured the same extractly. And there's not problem anymore.
Then, I tried ASR 1002 and it's in trouble again. Now, i have to use 2801.....
I have checked log and see:
*Feb 19 14:10:58.143: %QFPOOR-4-LOWRSRC_PERCENT: F0: cpp_ha: QFP 0 DRAM resource low - 97 percent depleted
*Feb 19 14:36:22.271: %QFPOOR-4-LOWRSRC_PERCENT: F0: cpp_ha: QFP 0 DRAM resource low - 98 percent depleted
*Feb 19 15:02:16.368: %QFPOOR-4-LOWRSRC_PERCENT: F0: cpp_ha: QFP 0 IRAM resource low - 99 percent depleted

I found : NAT is the feature that hold most of the memory. What can i do now

On the Cisco ASR 1000 Series Routers, IOS runs as one of many processes within the operating system. This is different than on traditional Cisco IOS, where all processes are run within Cisco IOS.
This architecture allows for software redundancy opportunities that are not available on other platforms that run Cisco IOS software. Specifically, a standby IOS process can be available on the same Route Processor as the active IOS process. This standby IOS process can be switched to in the event of an IOS failure, and can also be used to upgrade subpackage software in some scenarios as the standby IOS process in an ISSU upgrade.
Following Table shows Software Redundancy Overview:
Router
Support for Two IOS Processes on Same Route Processor
Support for a Second IOS Process on Standby Route Processor
Explanation
Cisco ASR 1001 Router1
Yes
N/A
The Cisco ASR 1001 Router only supports one RP, so dual IOS processes run on the lone RP.
Cisco ASR 1002 Router
Yes
N/A
The Cisco ASR 1002 Router only supports one RP, so dual IOS processes run on the lone RP.
Cisco ASR 1004 Router
Yes
N/A
The Cisco ASR 1004 Router only supports one RP, so dual IOS processes run on the lone RP.
Cisco ASR 1006 Router
No
Yes
The Cisco ASR 1006 Router supports a second Route Processor, so the second IOS process can only run on the standby Route Processor.

Report Performance Issue - Activity

Hi gurus,
I'm developing an Activity report using Transactional database (Online real time object).
the purpose of the report is to list down all contacts related activities and activities NOT related to Contact by activity owner (user id).
In order to fullfill that requirment I've created 2 report
1) All Activities related to Contact -- Report A
pull in Acitivity ID , Activity Type, Status, Contact ID
2) All Activities not related to Contact UNION All Activities related to Contact (Base report) -- Report B
to get the list of activities not related to contact i'm using Advanced filter based on result of another request which is I think is the part that slow down the query.
<Activity ID not equal to any Activity ID in Report B>
Anyone encountered performance issue due to the advanced filter in analytic before?
any input is really appriciated
Thanks in advanced,
Fina

Fina,
Union is always the last option. If you can get all record in one report, do not use union.
since all records, which you are targeting, are in the activity subject area, it is not nessecery to combine reports. add a column with the following logic
if contact id is null (or = 'Unspecified') then owner name else contact name
Hopefully, this is helping.
