Data Cache Vs Data Retreival buffers

Hello All-
I want to know how does the increase / decrease of data cache effects the size of Data retreival buffer size?
I was going through dbag and it says
*"When you retrieve data into Essbase Spreadsheet Add-in for Excel or use Report Writer to retrieve data, Essbase uses the retrieval buffer to optimize the retrieval"*
Is there any interdependence between data cache size and data retreival buffer?
Moreover in dbag i found in section "Enabling Dynamic Retrieval Buffer Sizing" as follows:
If a database has very large block size and retrievals include a large percentage of cells from each block across several blocks, consider setting the VLBREPORT option to TRUE in the Essbase configuration file essbase.cfg.
Has anybody used this command in past and can let me know the pros and cons of it?
Thanks!

Hello Glenn-
Thanks for the reply. On reading dbag ahead it states:
When the VLBREPORT setting is TRUE, Essbase internally determines an optimized retrieval buffer size for reports that access more than 20% of the cells in each block across several blocks. This setting takes effect only if the outline does not include Dynamic Calc, Dynamic Times Series, or attribute members.
The above sentence in bold what does that mean? It seems to be a vague statement as i cant imagine of an outline which dont have dynamic calc or dynamic time series enabled. Moreover my outline has 6 different attribute dimensions as well.
If i understood it correctly and i put this command in config file and have any of the above mentioned constraints (Dynamic Calc, Dynamic Times Series, or attribute members) in outline it will not work ??
There is another quick question not related to this post i was going through my application configuration file and here is a copy of it:
*; The following entry specifies the full path to JVM.DLL JvmModuleLocation E:\Hyperion\common\JRE\Sun\1.5.0\bin\client\jvm.dll SharedServicesLocation admin.companyname.int 58080 AuthenticationModule CSS http://admin.companyname.int:58080/interop/framework/getCSSConfigFile AGENTDESC ESSBASE Service*
CALCLOCKBLOCKHIGH 500
CALCLOCKBLOCKDEFAULT 200
CALCLOCKBLOCKLOW 50
The sentence that is marked as bold whats the purpose of that statement in confirg file ? Do we need it in our configuration file or we can delete it?
Thanks!

Data Cache Settings

Hello,
I am coming up with the spreadhseet retreival error very frequently and get Essbase Error 1130203. I went through the Error interpretation and found that Data Cache might be causing it. Here are the details of cache settings on my
databases currently. Can somebody please help me understand if they are right or need some changes:
DataBase A:
Data File Cache setting (KB) 32768
Data cache setting (KB) 100000
Block Size: (B) 143880
Number of existing blocks: 7266
Page file size: 40034304
DataBase B:
Data File Cache setting (KB) 32768
Data cache setting (KB) 300000
Block Size: (B) 91560
Number of existing blocks: 1912190
Page file size:2147475456--1
Page file size: 500703056
DataBase C:
Data File Cache setting (KB) 300000
Data cache setting (KB) 37500
Block Size: (B) 23160
Number of existing blocks: 26999863
Page File Size: 21 page file =21 * 2= 42 GB
If this might not be the issue then please let me know what might be causing it?
Thanks!

Hi,
1. For error no 1130203, here are the possible problems and solutions, straight from document.
Try any of the following suggestions to fix the problem. Once you fix the problem, check to see if the database is corrupt.
1. Check the physical memory on the server computer. In a Windows environment, 64 MB is the suggested minimum for one database. In a UNIX environment, 128 MB is the suggested minimum for one database. If the error keeps occuring, add more memory to the server computer.
2. If you are on a UNIX computer, check the user limit profile.
3. Check the block size of the database. If necessary, reduce the block size.
4. Check the data cache and data file cache setting. If necessary, decrease the data cache and data file cache sizes.
5. Make sure that the Analytic Services computer has enough resources. Consult the Analytic Services Installation Guide for a list of system requirements. If a resource-intensive application, such as a relational database, is running on the same computer, the resource-intensive application may be using the resources that Analytic Services needs

Data File Cache / Data Cache

I have a few Questions regarding Data File cache and data cache. based on teh size of the application.
All the settings are changed by using a maxl script.
1. Data File cache-50MB,Data Cache - 100MB
I am using Buffered I/O, then will memory be allocated to Data File cache?
2. It is given in DBAG that data cache & index cache should be set as small as
possbile for both buffered & Direct I/O. The size of one of my application is
around 11 GB. data file :11GB,index File :450MB
I have set my index cache to 450MB and data cache to 700MB.
Is it OK or a. what should be my data cache size?
b. How do I calculate the optimal Data cache and index cache?
3. the memory size of our AIX server is 6GB. If i use Directo I/O, can my sum of
all caches be 4GB?
4. If I use buffered I/O, according to (2), what should be my cache sizes?
Thanks
Amarnath

In the DBAG it states data file cache is not used with buffered IO so the answere to 1) should be NO.
For 2) there is a hint in the DBAG that you should check the hit ratio of the caches to verify sizing, only calculatory advice for sizing is given on the calulator cache :-( This would mean for 2b) look at the hit ration if it stays around 1.0 try to decrease it until it drops slightly. Inspect the ratios from time to time.
3) don't know, 64bit should be no problem. But why would you do this anyway?
Example form our settings pag total ~20GB ind ~2GB
outline hat 11 dimensions with a block size of ~340KB largest dense ~400 members, largest sparse ~4000 members, existing blocks ~2.7 milions
The data cache is set to 256 MB, the index cache to 64MB our hit ratios are 1.0 for index cache and 0.77 for data chache. so our data cache could be larger, but the performace of retrievals is around 3.0 seconds which is fine for our users..
4) Check your hit ratios and try to increase or decrease the cahces in small steps (first I'd do the index cache, the if it's fine I'd tune the data cache).
hope it helped a bit..

Essbase data cache setting not registering

Hi,
We have 64-bit essbase. I changed the data and Index cache setting (storage type Buffered IO) in essbase.
After restarting the database, I see the value getting updated in the "Index cache current value" but the value in the "Data cache current value" is zero.
These are planning essbase databases. The behavior is same for the native essbase dbs.
I have also tried restarting the essbase service. The essbase version 11.1.1.3
Please help.
Regards,
Avi

Indes and data caches work differently and it is probably good to talk about that. When an Essbase database starts, it will grab all of the memory you have defined for the index cache and nothing else can get at it. Data cachs is grabbed as it is needed until it reaches the maximum. It was truly problematic in the old days when we had much less memory to work with. If you started too many applications, you took all available memory right away. Man I feel old talking about it :)

Need input on data cache

Hi All,
This is the situation..
Data cache = 3mb (default)
Data block size = 20kb
so number of blocks a memory segment (data cache) can hold is 157
What will happen If user is retrieving 300 blocks in one retrieval ?
I know swapping will takes place for multiple retrievals.
I know that agg cache in ASO will increase till OS say no it.
Will Essbase tries to increase data cache....?? if so how it works??
My understanding is Essbase tries to increase data cache and it may touch the wrong segment in memory to create a segment violation to crash!!
As per the modern OS, virtual memory management using pages and segments ...I think this will takes place!!
Please give your inputs!!
Thanks,
Jeeth

Hi,
I just did an initial analysis....
It is always 3mb. (never increased it)!!
XCP log says it stopped at executing the maxl!! ..like (Maxl pending)
and its an segmentation violation!!
from my understanding segmentation violation is something to do with kernal memory allocation, virtual memory and physical memory.
I cannot try the same on prod server (pls don't ask why the settings are default etc ..I'm new to the system)
I just provided an intial analysis telling that at this point of time...the highly visible point to me is data cache in buffered I/o.
The segmentation violation can also happen at total level of availability of RAM.
but in our case we are using only 1/3rd of the Total available RAM.
memory in all applications = (1/3rd of available RAM)
and its a Maxl operation...
by seeing al this i suspected the application cache.(data cache)
I posted only to gather little mor info and to have a debate to get clear understanding.
Thanks for your support and input...
Please advice
Thanks,
Jeeth

How to remove objects cached in data cache?

With following query, I can find out how the table cached in data cache with the indexes:
Select CacheName,DBName,OwnerName,ObjectName,IndexID,sum(CachedKB) as "CachedKb"
from master..monCachedObject
where ObjectName = 'invent'
group by CacheName,DBName,OwnerName,ObjectName,IndexID
order by CacheName,DBName,OwnerName,ObjectName,IndexID
Is it possible to remove the cached data for particular index from data cache? I want to verify the performance issue is on particular index and reproduce the performance issue.

SImply unbind the objects from their named cache. Then, bind the objects again back to their named cache. The "re-bind" step doesn't have to be done if we are talking about "default data cache".
For objects bound to named cache other than "default data cache":
exec sp_unbindcache <dbname>,<tablename>,<indexname>
exec sp_bindcache <cachename>,<dbname>,<tablename>,<indexname>
Now data will be read from disk on first retreival.
For "default data cache" objects:
exec sp_unbindcache <dbname>,<tablename>,<indexname>

Low Hit Ratio on Data Cache

currently I hitting a performance issue on low data cache hit ratio (~0.5 after each calculation). Is there anyway to improve the hit ratio. I have been increased the size of data cache by 50%, however only have a litte improve.Is the bottleneck on I/O? How to improve?Our Essbase Version is 6.2.1 and using Buffered I/O.ThanksLouis

ok,.. the cache hit ratio indicates the percentage of time that a requested piece of information is already in the cache. A higher hit ratio indicates that the data is in the cache more often. This improves performance because the requested data does not have to be retrieved from disk for the next process. it sound like you must have a pretty sparse database,... you might be able to raise the rit ratio by using RLE compression over bit-map if your database is very sparse or has a lot of repeating values. you have to export all the data | clear the database | change the compression type to RLE | re-load the export file | and then calculate to see if it make much difference. (you have to export all data and then reload it so that you don't have mixed compression types) hope that helps you out.

Web Application - Data caching of enterprise data

Sorry in advance if this is off-topic but I can't find anywhere else to post this type of question.
I am looking for information/suggestions such as books, technology or design methodology for my enterprise web applications. These sites are currently up and functional using only JSP, servlets and regular Java classes stored in a web application session to provide data caching and access. We are using Weblogic Server 6.1 running on an AIX Unix system at this time. I'm not sure that this is the best design architecture as our web sessions are getting too large but I can't think of any other Java technology to use and I need some help. Here's an overview of our environment and our needs.
Our core data is held in a mainframe based IMS system. Some DB2 is also used. Access to this data is through IMS COBOL transactions which we can execute with IMS Connect. We also use some JDBC to get to the DB2 tables directly where available.
Some overall application data is cached when the web application is deployed. We use singleton classes which are created and refreshed at deployment and they then refresh themselves from the sources every 24 hours.
Each time a user logs in we execute several IMS transactions and JDBC calls to cache user specific data in regular Java classes which are then simply placed in the users web session where we access them from JSP, servlets and other Java classes. The fields in these Java classes range from any type of primitive field to TreeMaps of other Java classes. As the data is cached it is sorted and other fields are calculated and stored in these classes. As the user progresses through the system we then may have to do several other IMS transaction and JDBC calls to collect other types of data. All of this is then also added to the users session. Most of this in inquiry. We do allow transactions but those are built from user input and data already cached and are then we just execute the IMS transactions with the input.
As our application has grown these Java classes have gotten larger and larger. And since these are simply stored in server memory in the web sessions then these are also getting huge. I'm concerned that this is not the best way for this application to be architected. Is there something else we should be doign? I simply don't understand how Entity Java Beans could be used but then again I don't know much about them. I wouldn't think that caching the data to a local database and accessing it from there would be any more efficient and would probably just slow down the system from all the I/O.
Any help or direction would be greatly appreciated.

The best book you can buy is 'Professional Java Server Programming, j2ee edition' by Wrox. It is by far the best reference I've used. Another quick reference consideration might be the j2ee book provided by codenotes... its quick and to the point.

How can I Cache the data I'm reading from a collection of text files in a directory using a TreeMap?

How can I Cache the data I'm reading from a collection of text files in a directory using a TreeMap? Currently my program reads the data from several text files in a directory and the saves that information in a text file called output.txt. I would like to cache this data in order to use it later. How can I do this using the TreeMap Class? These are the keys,values: TreeMap The data I'd like to Cache is (date from the file, time of the file, current time).
import java.io.*;
public class CacheData {
public static void main(String[] args) throws IOException {
String target_dir = "C:\\Files";
String output = "C:\\Files\output.txt";
File dir = new File(target_dir);
File[] files = dir.listFiles();
// open the Printwriter before your loop
PrintWriter outputStream = new PrintWriter(output);
for (File textfiles : files) {
if (textfiles.isFile() && textfiles.getName().endsWith(".txt")) {
BufferedReader inputStream = null;
// close the outputstream after the loop
outputStream.close();
try {
inputStream = new BufferedReader(new FileReader(textfiles));
String line;
while ((line = inputStream.readLine()) != null) {
System.out.println(line);
// Write Content
outputStream.println(line);
} finally {
if (inputStream != null) {
inputStream.close();

I don't understand your question.
If you don't know how to use TreeMap why do you think a TreeMap is the correct solution for what you want to do?
If you are just asking how to use TreeMap then there are PLENTY of tutorials on the internet and the Java API provides the methods that area available.
TreeMap (Java Platform SE 7 )
Are you sure you want a map and not a tree instead?

Dynamic Calc processor cannot lock more than [100] ESM blocks during the calculation, please increase CalcLockBlock setting and then retry(a small data cache setting could also cause this problem, please check the data cache size setting).

Hi,
Our Environment is Essbase 11.1.2.2 and working on Essbase EAS and Shared Services components.One of our user tried to run the Cal Script of one Application and faced this error.
Dynamic Calc processor cannot lock more than [100] ESM blocks during the calculation, please increase CalcLockBlock setting and then retry(a small data cache setting could also cause this problem, please check the data cache size setting).
I have done some Google and found that we need to add something in Essbase.cfg file like below.
1012704 Dynamic Calc processor cannot lock more than number ESM blocks during the calculation, please increase CalcLockBlock setting and then retry (a small data cache setting could also cause this problem, please check the data cache size setting).
Possible Problems
Analytic Services could not lock enough blocks to perform the calculation.
Possible Solutions
Increase the number of blocks that Analytic Services can allocate for a calculation:
Set the maximum number of blocks that Analytic Services can allocate to at least 500.
If you do not have an $ARBORPATH/bin/essbase.cfg file on the server computer, create one using a text editor.
In the essbase.cfg file on the server computer, set CALCLOCKBLOCKHIGH to 500.
Stop and restart Analytic Server.
Add the SET LOCKBLOCK HIGH command to the beginning of the calculation script.
Set the data cache large enough to hold all the blocks specified in the CALCLOCKBLOCKHIGH setting.
Determine the block size.
Set the data catche size.
Actually in our Server Config file(essbase.cfg) we dont have below data added.
CalcLockBlockHigh 2000
CalcLockBlockDefault 200
CalcLockBlocklow 50
So my doubt is if we edit the Essbase.cfg file and add the above settings and restart the services will it work? and if so why should we change the Server config file if the problem is with one application Cal Script. Please guide me how to proceed.
Regards,
Naveen

Your calculation needs to hold more blocks in memory than your current set up allows.
From the docs (quoting so I don't have to write it, not to be a smarta***:
CALCLOCKBLOCK specifies the number of blocks that can be fixed at each level of the SET LOCKBLOCK HIGH | DEFAULT | LOW calculation script command.
When a block is calculated, Essbase fixes (gets addressability to) the block along with the blocks containing its children. Essbase calculates the block and then releases it along with the blocks containing its children. By default, Essbase allows up to 100 blocks to be fixed concurrently when calculating a block. This is sufficient for most database calculations. However, you may want to set a number higher than 100 if you are consolidating very large numbers of children in a formula calculation. This ensures that Essbase can fix all the required blocks when calculating a data block and that performance will not be impaired.
Example
If the essbase.cfg file contains the following settings:
CALCLOCKBLOCKHIGH 500 CALCLOCKBLOCKDEFAULT 200 CALCLOCKBLOCKLOW 50
then you can use the following SET LOCKBLOCK setting commands in a calculation script:
SET LOCKBLOCK HIGH;
means that Essbase can fix up to 500 data blocks when calculating one block.
Support doc is saying to change your config file so those settings can be made available for any calc script to use.
On a side note, if this was working previously and now isn't then it is worth investigating if this is simply due to standard growth or a recent change that has made an unexpected significant impact.

Dynamic action - Cache server data

APEX 4.2.2
Is there a way to cache server side data in a global (page/document level) Javascript vector (bunch of key-value pairs) (associative array, array of objects or some such)? This way the data can be used by subsequent dynamic actions' Javascript code without querying the server over and over.
I see that apex_util.json_from_sql is still undocumented after all these years. Are there any examples of using that API to do this sort of thing? Can someone please share?
Thanks

https://apex.oracle.com/pls/apex/f?p=57688:24
I took a shot at this and it seems to work well using Javascript global objects for data storage. Hope this helps someone.
1. Page attributes - Javascript global variables var gData,gLookup={};2. On-demand application process Get_Emps as apex_util.json_from_sql('select empno,ename from emp');3. Page Load dynamic action to invoke the application process and cache the data var get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=Get_Emps',$v('pFlowStepId'));
var retval=get.get();get=null;
gData=apex.jQuery.parseJSON(retval);
$.each(gData.row,function(i,obj){
gLookup[obj.EMPNO]=obj.ENAME;
});4. EMPNO page item - Standard OnChange dynamic action to SetValue of ENAME page item using the cached data - Javascript expression gLookup[$v(this.triggeringElement)]
We document something when it is ready to be supported. This specific procedure isn't something we haven't invested in, and thus, per our discretion, have elected not to document or support it at this time.Fair enough.

Xi Data Cache Refresh Problem

Hello,
We have following Problem:
We send an XML-Request with HTTP-Adapter to XI and get Data from R/3, works fine.
But when we send a Second Request we become an Error.
The error comes because in the Java Runtime the XI writes wrong values into Message.
When we do a XI Data Cache Refresh for INTEGRATION_SERVER
and INTEGRATION_RUNTIME we can send a message and all works fine again.´
Any Idea why the XI Caches Data from Request and set this values in the message of request that was send later?
Thanks,
Robin

Hi,
I think both are same. Because in SXi_ADM we also define our IS. so i think it may be same ...
If I am wrong please share your knowledge . in this thread for more clarification ..

Hi.
I encountered the same problem. In my case, the reason was that I created a new user for BAM (to be provided when installing BAM) but ran the installation under another user account. It seems like these users must be the same to make it work.

Data Cache Error

Hi Experts,
Im new in this forum and please tell me if Im in the wrong Forum.
I think the problem Im facing is a data cache one.
The Scenario is a proxy -> Web Sevice. Synchronous.
The Symptoms are: problems in the ESR. when im testing my scenario I get diferent errors depending on the refresh of the cache.
If I refresh the cache in the ABAP stack transaction sxi_cache. the error showed is: Operation Mapping XXXXXXXXX Runtime error Mapping program is not available in runtime cache
If I refresh the cache in the JAVA stack in the administration tool the error showed is: Receiver Determination Runtime error Error while refreshing the XI runtime cache
I never faced this before and cant find it in any other posts.
Thanks in advance and I hope you can help me.
Agus.
