Calculating HASH values with WCCP

Ok, I'm just not getting the HASH calculations. Can somebody please explain how the HASH values translate into subnets?
Thanks,
Patrick

Patrick,
I'm not a 100% sure of the algorithm used to determine what subnet is assigned to which WCCP bucket. However, I do know it involves an XOR of various L3 and L4 header fields in the packet.
To view the how the calculation has been performed you can run the hidden IOS command
show ip wccp hash <dst-ip> <src-ip> <dst-port> <src-port>
Router# show ip wccp 61 hash 0.0.0.0 10.88.81.10 0 0
WCCP hash information for:
    Primary Hash:   Src IP: 10.88.81.10
Bucket:   9
    WCCP Client: 10.88.81.12
Router#
Hope this helps,

Calculating hash values for really big files

I am using the following code to calculate the hash values of files
public static String hash(File f, String algorithm)
            throws IOException, NoSuchAlgorithmException {
        if (!f.isFile()) {
            throw new IOException("Not a file");
        RandomAccessFile raf = new RandomAccessFile(f, "r");
        byte b[] = new byte[(int) raf.length()];
        raf.readFully(b);
        raf.close();
        MessageDigest messageDigest = MessageDigest.getInstance(algorithm);
        messageDigest.update(b);
        return toHexString(messageDigest.digest());
    }Now the problem is, for really big files, 100 MB or over, I get an OutOfMemoryError.
I have used the -Xms and -Xms options to increase the JVM heap size, and untimately made it to work. However, I think this is lame and there is also a limit to the -Xmx option.
Is there any other way I can calculate the hash values of these really big files?
Thanks a lot in advance.

why do u open the file the way u do ?
why to u upload ALL the file AT ONCE into the memory ?
i would do it like this:
FileInputStream fis = new FileInputStream (f);
int fileSize = f.available();
byte buffer[] = new byte[1000];
MessageDigest messageDigest = MessageDigest.getInstance(algorithm);
for(int read = 0;read < fileSize;read +=1000;)
if(fis.available() > 1000)
fis.read(buffer, read, 1000);
else if(fis.available() > 0)
fis.read(buffer, read, fis.available());
else
break;
messageDigest.update(b);
fis.close();
return toHexString(messageDigest.digest());

Problem w. hash-value calculation for CLOB with DBMS_UTILITY.GET_HASH_VALUE

Hello Oracle-Experts,
I had to calculate hash-values for a corrorponding CLOB-field (see my post 'Buffer to small ORA-22835 error after migration from 9i to 10g' in forum 'database general').
I calculate the hash-values with the DBMS_UTILITY.GET_HASH_VALUE, e.g:
     SQL> SELECT DBMS_UTILITY.GET_HASH_VALUE(LPAD('X',3998,'X'),1,POWER(2,30)) FROM dual;
     DBMS_UTILITY.GET_HASH_VALUE(LPAD('X',3998,'X'),1,POWER(2,30))
     1053896858
Because the calculation failed with 10g I had taken a closer look at this function and realised the following results:
VALUE                                             DBMS_UTILITY.GET_HASH_VALUE(VALUE,1,POWER(2,30))
LPAD('X',3997,'X') 557754150
LPAD('X',3998,'X')      1053896858
LPAD('X',3999,'X')          888036750
LPAD('X',4000,'X') 162062978
LPAD('X',4001,'X')          162062978
LPAD('X',4002,'X') 162062978
LPAD('X',10000,'X') 162062978
It seems to me that I can't use this function for clob-values with a length greater than 4000 characters because of collisions. Maybe someone with experience
can give me a hint to handle this problem. Worst case i had to write my own CLOB_2_HASH function.
TIA + Best regards
Matthias

Yeah, the 4000-byte limit would be a factor in working CLOBs. I if you only had 4000 bytes you would not need a CLOB in the first place.
If you don't find something better then writing your own function might be the thing to do.

Forcing / reuse plan hash value ...

friends....
db: 11gr2
os: linux
for quite sometime I am trying to tune this query but somehow can't get runtime less than 35 seconds...
I tried to get recent plan details from sql id but saw database was using "Cardinality feedback used for this statement" and was showing me many different plan with different hash value ....
some of the plans are really good and finishes in 5 seconds and some took 55 seconds.
my question is
1. how can I force oracle to use/run query as per historic hash value with minimal runtime? is it possible?
2. can we see what hint or changes done in query by oracle for that particular hash value?
I can see explain plan but fail to use id/operation details in actual query?
my current explain plan slows at below operation id:
0. SELECT STATEMENT============12 rows======00:00:35
1. SORT ORDER BY===============12 rows======00:00:35
2. ---NESTED LOOPS OUTER==========12 rows=====00:00:35
3. -----NESTED LOOPS==============12 rows=====00:00:35
4. --------NESTED LOOPS ============ 12K rows ====00:00:01
5. ----------SORT UNIQUE=============4 rows=====00:00:01
...but hash value with good plan using "Hash Join Right Semi" for step-3 and "access table by index" for step 4...

using "Cardinality feedback used for this statement" and was showing me many different plan with different hash value ....
some of the plans are really good and finishes in 5 seconds and some took 55 seconds.A not unusual experience with cardinality feedback.
If you don't like the feature - and my experiences have been very mixed - turn it off.
Either via system wide parameter optimizeruse_feedback or on a statement basis using the parameter via opt_param hint or alter session.
1. how can I force oracle to use/run query as per historic hash value with minimal runtime? is it possible?a. SQL Plan Baselines
b. SQL Profile via COE_XFR_SQL_PROFILE.sql, see Oracle Support doc id 215187.1.
c. Hint the plan you want using the outline hints from plans above - see DBMS_XPLAN.DISPLAY_AWR and the format parameter '+OUTLINE'
2. can we see what hint or changes done in query by oracle for that particular hash value?See DBMS_XPLAN.DISPLAY_CURSOR / DISPLAY_AWR and the format parameter '+OUTLINE'
my current explain plan slows at below operation id:
but hash value with good plan using "Hash Join Right Semi" for step-3 and "access table by index" for step 4... You've got the template tuning threads which detail the information required to comment on this.

Calculation XML signature value with timestamp

I know how to calculate a signature value based on the elment "SignedInfo" in a xml document.
The problem is when a timstamp is used, hash value is also added to the signedinfo, but the calculation of the signature value is not the signature of that element, there is an extra calculation with that timestamp. Does anyone know the algorythm with timestamp?

If you are trying to add a timestamp to your document, put it into a SignatureProperty and include the property for the signautre calculation; see here for an example: XML dsig: Can I sign a SignatureProperty of the Signature?
If you are trying to do something else, you need to elaborate.

How can I find the element with the closest value to a calculated "target value" in a 1D array?

Hello all,
may be the following question is very simple, but I am relatively new in labview and it would be great if somebody could help me:
I have a acquaried 1D array of data-points. Now, I have to find the element in this array which value is the closest to a calculated "target value".
After finding the element with the value close to the "target value", I have to get the position of this element (i.e. the index) in the 1D array.
Now, I have to use this index to find and extract the element at this position in an other 1D array.
It would be very nice if somebody could help me with this problem.
Thank you,

The selected signed file could not be authenticated. The file might have been tampered with or an error might have occured during download. Please verify the MD5 hash value against the Cisco Systems web site

I am trying to load any 9.0.3 firmware on my UCM 5.0.4.2000-1 server. Every newer firmware I load throws the following error. I have verified the MD5 is correct and also downloaded the file several times with the same result. I can load the same firmware file on another UCM server and it loads fine. Any ideas?
Thanks in advance!

Firmware File: cmterm-7970_7971-sccp.9-0-3.cop.sgn
UCM version: 5.0.4.2000-1

Thanks for your reply. We have a lab environment where I maintain UCM 5.0, 5.1, 6.0, 6.1, 7.0, 7.1 and 8.0 servers each running the latest released firmware for our QA testing team. I have downloaded and installed the latest device packages but find that if I try to install any firmware newer then 8.3.1 on either 5.0.4 or 6.0 i start getting MD5 hash authentication errors. It looks like 9.0.3 firmware should work on UCM 5.0 and 6.0 so I am lost as to why I can't seem to update any firmware for any model phone if it is newer then version 8.3.1 on either 5.0 or 6.0. while 5.1 and 6.1 work without issues. Maybe it is just a bug. I mostly wanted to see if anyone else has experienced this or if it is just me.

Overwrite the system calculated VAT - Condition Value with Inbound VAT Amou

Hello experts:
We have a following requirement in my customer for Inbound VAT Processing.
We want to overwrite the system calculated VAT - Condition Value with Inbound VAT Amount
Details :
Aggregated sales Idoc ( WPUUMS01) is used here for posting the daily sale.
Inbound pricing procedure is ZPOS00 ( copy of POS000)
VAT is maintained with condition Type ZMWS. Using Tax Codes
When idoc get posted system calculates the ZMWS and working fine.
However we would like to overwrite this condition value with inbound condition value (from segment 5 of WPUUMS)
Example :
For Article A : inbound aggregated sales Amount= 100 INR and ZMWS is 10%( VAT code B1)
Then system will calculate 90 INR revenue and 10 INR as VAT
However due to rounding in POS system we may get from POS the VAT Amount =9.99 for example.
Tisak wants to overwrite the condition value 10 INR with 9.99 INR.
I will appreciate if anybody can suggest some approach or share experience if came across the same scenario (Tax condition type).
Thanks and regards,

Hi,
Either you can use rounding in POS such that it round up for 9.99 to 10.
And then in SAP pricing procedure you can use alternate calculation type as 16 or 17 (17 should be used with decimal point assigned to currency for rounding like 2 decimal for INR).
doing this will also round the figure from 9.99 to 10 is SAP.
Hope this solves your query.

Ashutosh

DBMS_CRYPTO MD5 hash value does not match 3rd party MD5 free tool

Hello,
I am using Oracle Version: 11.2.4.
I have a problem where the MD5 value from DBMS_CRYPTO does not match the hash value from 3rd party MD5 free tool (MD5 Checksum Calculator 0.0.5.58 or WinMD5Free v1.20) and also the MD5 hash value calculated by an ingestion tool where I am transferring files to. The MD5 hash value that the ingestion tool calculates is the same as the 3rd party MD5 free tools I have. This occurs only on some of the XML files that I generate using XSQL(xmlserialize, xmlagg, xmlelement, etc.) and DBMS_XSLPROCESSOR on a Linux OS. The XML files are transferred from the Unix OS to my Windows 7 OS via filezilla.

And in that thread (Re: MD5 HASH computed from DBMS_CRYPTO does not match .NET MD5 I provided the reason why DBMS_CRYPTO may not match hashes produced by other methodologies.
I have no idea why you copied and posted all of that Java code the other poster and I provided since code has NOTHING to do with the problem you say you are having. Thte other poster's question was how to write Java code that would produce the same result as DBMS_CRYPTO.
You said your problem was understanding why DBMS_CRYPTO 'does not match the hash value from 3rd party MD5 free tool ...'. and I answered that in the other forum.
>
The Crypto package always converts everything to AL32UTF8 before hashing so if the .NET character set is different the hash will likely be different.
See DBMS_CRYPTO in the PL/SQL Packages and Types doc
http://docs.oracle.com/cd/B28359_01/appdev.111/b28419/d_crypto.htm
If you look at the spec header for the DBMS_CRYPTO package it shows this note:
-- Prior to encryption, hashing or keyed hashing, CLOB datatype is
-- converted to AL32UTF8. This allows cryptographic data to be
-- transferred and understood between databases with different
-- character sets, across character set changes and between
-- separate processes (for example, Java programs).
-- If your 3rd party MD5 free tool (MD5 Checksum Calculator 0.0.5.58 or WinMD5Free v1.20) do not use the AL32UTF8 character set then the hashes will likely be different. You can't modify DBMS_CRYPTO so if the hashes need to match you need to use 3rd party tools that either use the correct character set or can be configured to use the correct character set.
The problem in the other thread was how to WRITE Java code that uses the correct character set and I showed that OP how to do that.
So unless you are writing your own Java code all of that code you copied and pasted is useless for your use case.

Hash Values in BODS

Hello Experts,
I am a newbie to Data Services. We are using Data Services XI 3.0 Premium. I was given a task to identify duplicates by using hash values so that there is no loss of data and at the same time we can identify the duplicates. I was able to find that functionality in Oracle. But client wants the functionality in Data Services, before it loads into Oracle. I looked everywhere, couldn't find the right information. Help would be really appreciated. Please let me know if any further information needed.
Thank you for going through my post. I really appreciate your time.
Thank you,
Sandeep.

Hi
As per your statement "to identify duplicates considering bunch of columns together" you can implement logic using BODS built in function "gen_row_num_by_group"
create new column in query transformation say "Dup_find" with data type int
write logic in mapping tab as below
gen_row_num_by_group( field1 || field2 || field3 || ....... ) and drag the subsequent fields in group by tab as well
the above logic will return the row ids per group
example
FIELD1     FIELD2     FIELD3     DUP_FIELD
A                    B                    C                    1
A                    B                    C                    2
A                    B                    C                    3
D                    E                    F                    1
G                    H                    I                     1
take two query transformations in parallel
In first query transformation, you have to filter the duplicate records using "WHERE" clause
WHERE DUP_FIELD > 1 ( map this to one temp table to catch duplicate records )
in second query transformation, you can consider only unique records using "WHERE" clause
WHERE DUP_FIELD = 1 ( map this to second temp table to catch unique records )
hope it helps in your requirement
Thanks

How to Implement a Chained Hash Table with Linked Lists

I'm making a migration from C/C++ to Java, and my task is to implement a Chained Hash Table with a Linked List. My problem is to put the strings(in this case names) hashed by the table using de Division Metod (H(k)= k mod N) in to a Linked list that is handling the colisions. My table has an interface implemented(public boolean insert(), public boolean findItem(), public void remove()). Any Help is needed. Thanks for everyone in advance.

OK. you have your hash table. What you want it to do is keep key/value pairs in linked lists, so that when there is a collision, you add the key/value pair to the linked list rather than searching for free space on the table.
This means that whenever you add an item, you hash it out, check to see if there is already a linked list and if not, create one and put it in that slot. Then in either case you add the key/value pair to the linked list if the key is not already on the linked list. If it is there you have to decide whether your requirements are to give an error or allow duplicate keys or just keep or modify one or the other (old/new).
When you are searching for a key, you hash it out once again and check to see if there is a linked list at that slot. If there is one, look for the key and if it's there, return it and if not, or if there was no linked list at that slot, return an error.
You aren't clear on whether you can simply use the provided linked-list implementations in the Java Collections or whether you have to cobble the linked list yourself. In any case, it's up to you.
Is this what you're asking?

Crystal 2008 not showing a Hash Value correctly

We are using a SQL database with Crystal 2008.
The Problem:
We are having some issues displays the hash value of a varchar(20) in our crystal reports. Every value in the field is either going to be a Null or 20 characters long. We are getting varying length characters, when it should not. And it is showing blank for some of the records when the double check shows that they exist.
What can we do to make Crystal 2008 show these fields correctly? I can use a command but that is a temporary solution for a reoccuring problem with the field in question.
Thank you for your time!
Dan

We use EncryptbyCert() function in SQL. It returns only a value that is either null or 20 characters long. That is all I am able to give for information about that.

Delete hash value row in Bex report output

Hi All,
Can anybody suggest how can i remove hash value(not assigned) row in Bex report out put.
my report looks like this:
rows
project position
(hierarchy)
WBS element
(hierarchy)
Order
For each Project position and WBS element hierarchies, i did supress the " not assigned" tick in hiearchy attributes in RSH1.
but in colums i have budget as one of the column.
this budget comes from project position nodes to last node of WBS element but not in order, for order it will be blank but after this order a new row coming up with bold" Not assigned" with that budget amount against this not assigned.
My problem is how can i get rid of this not assinged entire row. I search so many links in SDN, they talk about just to replace the not assigned to some other value as blank or something like that.
Please suggest me how can i get rid of this.
i did tried to restrict Order with "#" but then the whole budget column getting blank.
Regards
Robyn.

HI Arun,
As i mentioned earlier, i have gone through these links, they just talk about replacing # value or Not Assigned to some other value or blank.
my issue is i need to get rid of that entire row.
when i drop proj def hierarchy ,then wbs hierachy starts, sometimes at the end of wbs hierarchy i get row with #
and sometimes after wbs hierarchy ,then order row then # row is coming.
even after i tick supress unassigned nodes in both Projdef and wbs hierarchies.
i am not supposed to simply replace #( not assigned) symbol or text with some other symbol or text ( thats what they discussing in these links).
i created that macro they said in those links but its just deleting # symbol to blank not the whole row.
hope i made my issue clear.
i have seen so many other links as well
[Re: Bex macros]

Robyn.

Set JArray values with invalid key value: "LastUpdatedTime" on new alert rule creation

Hey all!
I'm trying to create a new alert rule using version 0.9.11 of the Monitoring Library and am getting this error on alertsClient.rules.CreateOrUpdate:
"Set JArray values with invalid key value: "LastUpdatedTime". Array position index expected."
That's interesting because LastUpdatedTime is a DateTime object, and whether I set it or I don't, if I set a breakpoint, it does set itself correctly, but the API appears to be expecting a JSON hash?
I've tested alertsClient and I'm able to get existing alerts (also metrics with metrics client), so I don't believe it's an access issue.
Any ideas?
The full code I'm using for the test (borrowed virtually verbatim from the Cloud Cover video
here):
Rule newRule = new Rule
Name = "CPU Over 90%",
Id = Guid.NewGuid().ToString(),
Description = "CPU Has been over 90% for 5 minutes",
IsEnabled = true,
LastUpdatedTime = DateTime.Now,
Condition = new ThresholdRuleCondition
Operator = Microsoft.WindowsAzure.Management.Monitoring.Alerts.Models.ConditionOperator.GreaterThan,
Threshold = 90,
WindowSize = TimeSpan.FromMinutes(5),
DataSource = new RuleMetricDataSource
MetricName = "Percentage CPU",
ResourceId = "",
MetricNamespace = ResourceIdBuilder.BuildCloudServiceResourceId(<cloudservicename>, <deploymentname>)
RuleAction action = new RuleEmailAction
SendToServiceOwners = true,
newRule.Actions.Add(action);
OperationResponse alertResponse = alertsClient.Rules.CreateOrUpdate(new
RuleCreateOrUpdateParameters { Rule = newRule });
Console.WriteLine("Create alert rule response: " + alertResponse.StatusCode);

Hi Greg,
Thanks for your post!
Error "JArray" has been fixed in the latest nugget package.
Refer to:
http://www.nuget.org/packages/Microsoft.WindowsAzure.Management.Monitoring/
Hope this helps!

Hi,
Characters whose hexadecimal value is 00-1F these will be displayed as # and we think this is maintained in RSKC and even then the load is failed... the invalid characters are displayed as # and there by u need to stop them . Even With ALL_CAPITAL u will not be able and it wont be good to use ALL_CAPITAL in rskc. this is part of code which i used to eliminate such cases.........and this is absolutely working fine... it will be invalid characters....
DATA: L_S_ERRORLOG TYPE RSSM_S_ERRORLOG_INT,
G_ALLOWED_CHAR(300) TYPE C.
IF G_ALLOWED_CHAR IS INITIAL.
CALL FUNCTION 'RSKC_ALLOWED_CHAR_GET'
IMPORTING
E_ALLOWED_CHAR = G_ALLOWED_CHAR.
ENDIF.
concatenate G_ALLOWED_CHAR 'abcdefghijklmnopqrstuvwxyz£Ö@[]' into G_ALLOWED_CHAR.
in the above concatentate statement add all the characters which u want to allow apart from the allowed characters .....**
do.
if not RESULT co g_allowed_char.
shift RESULT+sy-fdpos left.
else.
exit.
endif.
enddo.
Here result is the field for which say invalid characters are coming ...above is the code to remoce invalid characters from the field Result.....
