Limiting Zone memory consumption
So in a blurb about the 8/2007 (Update 4) Solaris 10 release I saw the following:
"Users will now be able to define how much memory and how many processors should be assigned to a particular application or container."
Memory limits could be a big deal. Anyone know if this is something more than the "pcap" daemon? Is it real memory limits?
"Users will now be able to define how much memory and how many processors should be assigned to a particular application or container."
Memory limits could be a big deal. Anyone know if this is something more than the "pcap" daemon? Is it real memory limits?You mean 'rcap'? What's the limitation you have with that?
I'm assuming that the blurb is referring to this stuff...

Limiting local-zone memory consuption...
Hey people...
from a "search" through the forums, it appears that this question has been asked before... (but I wasn't able to find an authoritative answer from a SUN person on this, so lets try again....)
Scenario:
- bunch of local-zones on a server.
- locked down disk-wise by using..... well, lets just say a really cool new file-system.
- locked down CPU-wise through FSS and share-assignment to each zone (FROM the global zone)
- plan to lock down total-processes through zone.lwp-max type deal with zoneadm. (haven't tried this yet)
- memory consumption is still a free-for-all however, and I'm somewhat stuck on this one...
so.. how do you recommend capping the total memory consumption for each zone?
* please set me straight if I'm overlooking something straight-forward, or point us to some docs.
The documentation suggests the possible use of rcapd or some such beast, but it appears that has to be run from WITHIN the local (non-trusted?) zone, which would somewhat defeat the purpose. Using pools to control memory may do the trick, but there is some sort of "one pool, one zone" statement I'm not clear on.
[ but again, that is probably just just me... ]
I don't want to "hard-partition" the box in such a way where I have to divide up the total memory into 20-pools, to then give each zone its own pool. I think what I'm after is some sort of "zone-A can use upto 2GB out of total mem, zone-B 1GB, zone-C 3GB and so on...... But without pre-allocating 2,1,3 GB of RAM exclusively to each zone.... Maybe you can do this with the multiple individual pools, but I'm not clear on it.
thanks for any assistance,

ITS 620 Template Cache - unlimited memory consumption
Hi,
We have patched standalone ITS 620 to 23 to resolve some issues we have with
the display of ITS screens via the Mozilla browser. However, we are now encountering memory issues where the Agate process is consuming much more than is allocated via the threads and sessions values.
With patch 23 we can now see the template cache value and it consumes all the free physical memory on the machine. The 'Cachesize' parameter is set to a much lower value than this:
Can anyone tell me:
1. Is this behaviour correct for this cache?
2. How do we disable the cache?
3. How do we restrict the size of the cache?
Thanks.
/regards,
Conor.Hi Conor,
ITS development is not aware of memory issues with PL 23.
The memory the template cache allocates does not depend on the "Cachesize" parameter. This parameter is for RFC connections of flowlogic services.
If after PL 23 you have Mozilla user you haven't before this would explain the increase of the template cache memory consumption. For each browser and language the amount of memory in the templates cache increases.
You surely could disable the templates cache but this would hit performance (switch parameter StaticTemplates to 0 in ITS Admin - <Your_Instance> Configuration - Performance). On each template access the template would have to be parsed again. This switch is intended for a development environment only.
The best you can do is to setup ITS server on 64-Bit OS and 64-Bit ITS 6.20 executables. On 64-Bit you can forget about memory issues due 32-Bit address space limitations.
If you this is not possible you have to reduce the memory by
- forwarding requests with specific languages to specific ITS instances
- forwarding request from Browsers like Mozilla to a specific ITS instances
- checking peak values in ITS Admin Overview and tune parameters MaxSessions, MaxWorkthreads accordingly. Be carefull!!
SAP note 720428 gives you advise about the most important ITS 6.20 parameters.
Best regards,

How to measure memory consumption during unit tests?
Hello,
I'm looking for simple tools to automate measurement of overall memory consumption during some memory-sensitive unit tests.
I would like to apply this when running a batch of some test suite targetting tests that exercise memory-sensitive operations.
The intent is, to verify that a modification of code in this area does not introduce regression (raise) of memory consumption.
I would include it in the nightly build, and monitor evolution of summary figure (a-ah, the "userAccount" test suite consumed 615Mb last night, compared to 500Mb the night before... What did we check-in yesterday?)
Running on Win32, the system-level info of memory consumed is known not to be accurate.
Using perfmon is more accurate but it seems an overkill - plus it's difficult to automate, you have to attach it to an existing process...
I've looked in the hprof included in Sun's JDK, but it seems to be targetted at investigating problems rather than discovering them. In particular there isn't a "summary line" of the total memory consumed...
What tools do you use/suggest?However this requires manual code in my unit test
classes themselves, e.g. in my setUp/tearDown
methods.
I was expecting something more orthogonal to the
tests, that I could activate or not depending on the
purpose of the test.Some IDEs display mmeory usage and execution time for each test/group of tests.
If I don't have another option, OK I'll wire my own
pre/post memory counting, maybe using AOP, and will
activate memory measurement only when needed.If you need to check the memory used, I would do this.
You can do the same thing with AOP. Unless you are using an AOP library, I doubt it is worth additional effort.
Have you actually used your suggestion to automate
memory consumption measurement as part of daily builds?Yes, but I have less than a dozen tests which fail if the memory consumption is significantly different.
I have more test which fail if the execution time is siginificantly different.
Rather than use the setUp()/tearDown() approach, I use the testMethod() as a wrapper for the real test and add the check inside it. This is useful as different test will use different amounts of memory.
Plus, I did not understand your suggestion, can you elaborate?
- I first assumed you meant freeMemory(), which, as
you suggest, is not accurate, since it returns "an
approximation of [available memory]"freeMemory gives the free memory from the total. The total can change so you need to take the total - free as the memory used.
- I re-read it and now assume you do mean
totalMemory(), which unfortunately will grow only
when more memory than the initial heap setting is
needed.more memory is needed when more memory is used. Unless your test uses a significant amount of memory there is no way to measure it reliably. i.e. if a GC is perform during a test, you can have the test appear to use less memory than it consumes.
- Eventually, I may need to inlcude calls to
System.gc() but I seem to remember it is best-effort
only (endless discussion) and may not help accuracy.if you do a System.gc(); followed by a Thread.yield() at the start it can improve things marginally. -
I have 24GB of RAM in my 64 bit Windows 7 system running on RAID 5 with an i7 CPU.
A while ago I updated from Premiere CS5 to CC and then from Premiere CC to CC 2014. I updated all my then current projects to the new version as well.
Most of the projects contained 1080i 25fps (1080x1440 anamorphic) MPEG clips originally imported (captured from HDV tape) from a Sony HDV camera using Premiere CS5 or CC.
Memory consumption during re-indexing.
When updating projects I experienced frequent crashes going from CS5 to CC and later going from CC to CC 2014. Updating projects caused all clips in the project to be re-indexed. The crashes were due to the re-indexing process causing excessive RAM consumption and I had to re-open each project several times before the re-index would eventually complete successfully. This is despite using the setting to limit the RAM consumed by Premiere to much less than the 24GB RAM in my system.
I checked that clips played; there were no errors generated; no clips showed as Offline.
Some Clips now Offline:Importer CC 2014
Now, after some months editing one project I found some of the MPEG clips have been flagged as "Offline: Importer" and will not relink. The error reported is "An error occurred decompressing video or audio".
The same clips play perfectly well in, for example, Windows Media Player.
I still have the earlier Premiere CC and the project file and the clips that CC 2014 importer rejects are still OK in the Premiere CC version of the project.
It seems that the importer in CC 2014 has a bug that causes it to reject MPEG clips with which earlier versions of Premiere had no problem.
It's not the sort of problem expected with a premium product.
After this experience, I will not be updating premiere mid-project ever again.
How can I get these clips into CC 2014? I can't go back to the version of the project in Premiere CC without losing hours of work/edits in Premiere CC 2014.
Any help appreciated. Thanks.To answer my own question: I could find no answer to this myself and, with there being no replies in this forum, I have resorted to re-capturing the affected HDV tapes from scratch.
Luckily, I still had my HDV camera and the source tapes and had not already used any of the clips that became Offline in Premiere Pro CC 2014.
It seems clear that the MPEG importer in Premiere Pro CC 2014 rejects clips that Premiere Pro CC once accepted. It's a pretty horrible bug that ought to be fixed. Whether Adobe have a workaround or at least know about this issue and are working on it is unknown.
It also seems clear that the clip re-indexing process that occurs when upgrading a project (from CS5 to CC and also from CC to CC 2014) has a bug which causes memory consumption to grow continuously while it runs. I have 24GB RAM in my system and regardless of the amount RAM I allocated to Premiere Pro, it would eventually crash. Fortunately on restarting Premiere Pro and re-loading the project, re-indexing would resume where it left off, and, depending on the size of the project (number of clips to be indexed), after many repeated crashes and restarts re-indexing would eventually complete and the project would be OK after that.
It also seems clear that Adobe support isn't the greatest at recognising and responding when there are technical issues, publishing "known issues" (I could find no Adobe reference to either of these issues) or publishing workarounds. I logged the re-index issue as a bug and had zero response. Surely I am not the only one who has experienced these particular issues?
This is very poor support for what is supposed to be a premium product.
Lesson learned: I won't be upgrading Premiere again mid project after these experiences. -
Query on memory consumption during SQL
Hi SAP Gurus,
Could I kindly request for your inputs concerning the following scenario?
To put it quite simply, we have a program where we're required to retrieve all the fields from a lengthy custom table, i.e. the select statement uses an asterisk. Unfortunately, there isn't really a way to avoid this short of a total overhaul of the code, so we had to settle with this (for now).
The program retrieves from the database table using a where clause filtering only to a single value company code. Kindly note that company code is not the only key in the table. In order to help with the memory consumption, the original developer had employed retrieval by packages (also note that the total length of each record is 1803...).
The problem encountered is as follows:
- Using company code A, retrieving for 700k entries in packages of 277, the program ran without any issues.
- However, using company code B, retrieving for 1.8m in packages of 277, the program encountered a TSV_TNEW_PAGE_ALLOC_FAILED short dump. This error is encountered at the very first time the program goes through the select statement, ergo it has not even been able to pass through any additional internal table processing yet.
About the only biggest difference between the two company codes is the number of corresponding records they have in the table. I've checked if company code B had more values in its columns than company code A. However, they're just the same.
What I do not quite understand is why memory consumption changed just by changing the company code in the selection. I thought that the memory consumed by both company codes should be the same... at least, in the beginning, considering that we're retrieving by packages, so we're not trying to get all of the records all at once. However, the fact that it failed at the very beginning has shown me that I'm gravely mistaken.
Could someone please enlighten me on how memory is consumed during database retrieval?
Thanks!Hi,
with FAE (FOR ALL ENTRIES) the whole query even for a single record in the itab is executed and all results for
the company code are transfered from the database to the DBI since the duplicates will be removed by the DBI
not by the database.
If you use package size the resultset is buffered in a system table in the DBI (which allocates memory from your user quota). And from there on the package sizes are built and handed over to your application (into table lt_temp).
see recent ABAP documentation:
Since duplicate rows are only removed on the application server, all rows specified using the WHERE condition are sometimes transferred to an internal system table and aggregated here. This system table has the same maximum size as the normal internal tables. The system table is always required if addition PACKAGE SIZE or UP TO n ROWS is used at the same time. These do not affect the amount of rows transferred from the database server to the application server; instead, they are used to transfer the rows from the system table to the actual target area.
What you should do:
calculate the size needed for your big company code B. How many row multiplied with line length.
That is the minimum amount you need for your user memory quota. (quotas can be checked with
ABAP report RSMEMORY) If the amount of memory is sufficient then try without packagesize.
SELECT * FROM <custom table>
INTO TABLE lt_temp
FOR ALL ENTRIES IN lt_bukrs
WHERE bukrs = lt_bukrs-bukrs
ORDER BY primary key.
This might actually use less memory than the package size option for the FOR ALL ENTRIES.
Since with FAE it is buffered anyway in the DBI (and subtracted from your quota) you can
do it right away and avoid double saving portions (the DBI buffer and a portion of that in the
packe in lt_temp).
If the amount of memory is still too big, you have to either increase the quotas or select
less data (additional where conditions) or avoid using FAE in this case in order to not read all
the data in one go.
Hope this helps,

How to get information about limitation Internal Memory on device
hallo ..
have some question here, so please some person able to answer my questions
1. How to get Information about limitation internal memory on device
2. is possible to improve internal memory on Blackberry ( move apps on external memory )
3. any tools to get internal memory activity ?
thanks for this people who joins here, hope we can share more information about blackberry ..In addition...
There are three types of potential memory on a BB: 1) Application Memory, 2) Device Memory, and 3) Media/SD Card Memory.
Application Memory -- This is the most crucial; it is the protected (not user accessible), dedicated, and fixed (in size) space that is available as the destination for the installation of applications (plus some application storage, overhead and such). You cannot touch AppMemory. You cannot improve the maximum AppMemory that your BB has. It is what it is. Applications can only install here...there is no option.
Device Memory -- This is space on your BB that you can touch to store files, pictures, media, etc. Typically, it is not terribly large, but it is available to you.
SD/Media Card Memory-- This is what it says...your SD card, for you to store files, media, pictures, etc. It can be as large as your BB OS can support...see this KB:
KB05461MicroSD card sizes supported by the BlackBerry device software
On some devices/OS levels, you can only see "File Free" (Options > Status), which I think is equivalent to AppMemory. On other devices, you can see all three memory usage levels (Options > Memory). Here are some guidelines to use:
KB02843What is the Low Memory Manager feature on the BlackBerry smartphone
KB14320How to maximize free space and battery power on the BlackBerry smartphone
KB14213Call logs, SMS text messages, and email messages are deleted from the BlackBerry smartphone
Lastly, it is always important to properly close applications when you are done with them. Using the Back or the Red key will not do this -- those leave it to the app to decide what to do...and some will leave themselves resident in memory, consuming resources on your BB, slowing the overall performance. Rather, to close an app, press and select "Close" or "Exit"...that will force the application to be closed, freeing up for your new use the resources it was consuming. Some apps will always remain running (typically -- BBMessenger, Browser, Homescreen, Phone, and Messages)...but, you should still close them properly - especially the Browser...if it is left on an active web page, it will not only consume extra resources but battery power as well.
Further, anytime random strange behavior or sluggishness creeps in, the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation. Like all computing devices, BB's suffer from memory leaks and such...with a hard reboot being the best cure. Some have taken to doing this on a regular basis as a preventive measure...some as frequently as once per day. Others have obtained the QuickPull app to automate a simulated Batt-Pull.
Good luck!

Is there any limitation of memory uses for apps in iPad2 or iPad3 ?
Hi,
Is there any limitation of memory uses for apps in ipad2 or ipad3 .For example an application can use 10% or 20% of available memory , is there anything like that or the apps can use the total available memory or like 90% of it ?
I want to know about the memory distribution to the apps in ios .
Would anyone suggest a right way ?
ThanksiOS manages all memory. You should test your app in Instruments to be sure it is playing nice.

Integration Builder Memory Consumption
Hello,
we are experiencing very high memory consumption of the Java IR designer (not the directory). Especially for loading normal graphical idoc to EDI mappings, but also for normal idoc to idoc mappings. examples (RAM on client side):
- open normal idoc to idoc mapping: + 40 MB
- idoc to edi orders d93a: + 70 MB
- a second idoc to edi orders d93a: + 70 MB
- Execute those mappings: no additional consumption
- third edi to edi orders d93a: + 100 MB
(alle mappings in same namespace)
After three more mappings RAM on client side goes on 580 MB and then Java heap error. Sometimes also OutOfMemory, then you have to terminate the application.
Obviously the mapping editor is not quite will optimized for RAM usage. It seems to not cache the in/out message structures. Or it loads for every mapping very much dedicated functionality.
So we cannot really call that fun. Working is very slow.
Do you have similar experiences ? Are there workarounds ? I know the JNLP mem setting parameters, but the problem is the high load of each mapping, not only the overall maximum memory.
And we are using only graphical mappings, no XSLT !
We are on XI 3.0 SP 21

Check Process memory consumption and Kill it
Hello
I have just installed Orchestrator and have a problem that I think is perfekt for Orchestrator to handle.
I have a process that sometimes hangs and the only way to spot it is that the memory consumption has stoped.
The process is started every 15 minutes and scans a folder, if it finds a file it reads the file to a system. You can see that it is working by the increasing Memory consumption. If the read fails then the memory consumption stops. The process is still working
and is responding but is hung.
I'm thinking about doing a runbook that checks the memory-consumption every 5 minutes and compares it with the previous value. if the last three values are the same then I will kill the process and start it again.
My problem is that I have not found a way to check the memory consumption of a process.
I have set up a small test, just verify that I get the correct process, with the activity Monitor process -> Get Process Status -> Append Line (process name).
But How do I get the process memory consumption?
/AndersNow that I think about it a bit more I don't think there will be an easy way to set up a monitor for your situation in SCOM. Not that it couldn't be done, just not easily. Getting back to SCORCH. What you are trying to do isn't an every day kind of
scenario. I don't think there is a built in activity for this.
The hardest thing to overcome whether you use SCORCH or SCOM is likely going to be determining the error condition of three consecutive samples of the same memory usage. you'll need a way to track the samples. I can't think of a good way to do
this without utilizing scripting. -
High memory consumption in XSL transformations (XSLT)
Hello colleagues!
We have the problem of a very high memory consumption when transforming XML
files with CALL TRANSFORMATION.
Code example:
CALL TRANSFORMATION /ipro/wml_translate_cls_ilfo
SOURCE XML lx_clause_text
RESULT XML lx_temp.
lx_clause_text is a WordML xstring (i.e. it is a Microsoft Word file in XML
format) and can therefore not be easily splitted into several parts.
Unfortunately this string can get very huge (e.g. 50MB). The problem is that
it seems that CALL TRANSFORMATION allocates memory for the source and result
xstrings but doesn't free them after the transformation.
So in this example this would mean that the transformation allocates ~100MB
memory (50MB for source, ~50MB for result) and doesn't free it. Multiply
this with a couple of transformations and a good amount of users and you see
we get in trouble.
I found this note regarding the problem: 1081257
But we couldn't figure out how this problem could be solved in our case. The
note proposes to "use several short-running programs". What is meant with
this? By the way, our application is done with Web Dynpro for ABAP.
Thank you very much!
With best regards,
Mario DüsselHi,
q1. how come the Ram consumption is increased to 99% on all the three boxes?If we continue with the theory that network connectivity was lost between the hosts, the Coherence servers on the local hosts would form their own clusters. Prior to the "split", each cache server would hold 1/12 of the primary and 1/12 of the backup (assuming you have one backup). Since Coherence avoids selecting a backup on the same host as the primary when possible, the 4 servers on each host would hold 2/3 of the cache. After the spit, each server would hold 1/6 of the primary and 1/6 of the backup, i.e., twice the memory it previously consumed for the cache. It is also possible that a substantial portion of the missing 1/3 of the cache may be restored from the near caches, in which case, each server would then hold 1/4 of the primary and 1/4 of the backup, i.e., thrice the memory it previously consumed for the cache.
q2: where is the cache data stored in the coherence servers?on which memory?The cache data is typically stored in the jvm's heap memory area.
Have you reviewed the logs?

Query on Memory consumption of an object
Hi,
I am able to get information on the number of instances loaded, the memory occupied by those instances using heap histogram.
Class Instance Count Total Size
class [C 10965 557404
class [B 2690 379634
class [S 3780 220838
class java.lang.String 10807 172912 Is there way to get detailed info like, String object of which class consume much memory.
In other words,
The memory consumption of String is 172912. can I have a split up like
String Objects of Class A - 10%
String Objects of Class B - 90%
ThanksI don't know what profiler you are using but many memory profilers can tell you where the strings are allocated.

I have a query that returns about 10MB worth of data when run against my db -- it looks something like the following
'for $doc in collection("VcObjStore")/doc
where $doc[@type="Foo"]
return <item>{$doc}</item>'
when I run this query in dbxml.exe, I see memory footprint (of dbxml.exe) increase 125MB. Once query finishes, it comes back down.
I expected memory consumption to be somewhat larger than what the query actually returns but this seems quite extreme.
Is this behavior expected? What is a general rule of thumb on memory usage with respect to result size (is it really 10x)? Any way to make it less of a hog?
ThanksHi Ron,
Thanks for a quick reply!
- I wasn't actually benchmarking DBXML. We've observed large memory consumption during query execution in our test application and verified the same issue with dbxml.exe. Since dbxml.exe is well understood by everyone familiar with DBXML, I thought it would help starting with that.
- Yes, an environment was created for this db. Here is the code we used to set it up
EnvironmentConfig envConfig = new EnvironmentConfig();
envConfig.setInitializeLocking(true);
envConfig.setInitializeCache(true);
envConfig.setAllowCreate(true);
envConfig.setErrorStream(System.err);
envConfig.setCacheSize(1024 * 1024 * 100);
- I'd like an explanation on reasons behind the performance difference between these two queries
Query 1:
dbxml> time query 'for $doc in collection("VcObjStore")/doc
where $doc[@type="VirtualMachine"]
return $doc'
552 objects... <snip>
Time in seconds for command 'query': 0.031
Query 2:
dbxml> time query 'for $doc in collection("VcObjStore")/doc
where $doc[@type="VirtualMachine"]
return <val>{$doc}</val>'
552 objects... <snip>
Time in seconds for command 'query': 5.797
- Any way to make the query #2 go as fast as #1?

Memory consumption of queries in workbooks
We have an issue with the exceution of a Workbook which contains several queries. The queries require very much memory which finally leads to a shortdump (TSV_TNEW_PAGE_ALLOC_FAILED). We found that during execution of the workbook the memory is not released after a query has been executed and therfore at some point of time the dump occurs. However, if the queries are refreshed manually one after the other in the workbook the memory is relaesed and finally the workbook can be executed by this workaround.
My question is, if anyone has an idea, if it is possible to apply a setting somewhere that the queries relaese the memory after execution when they are all refreshed together in the workbook?
Thanks a lot in advance for any hint & Kind regards,
Hans-JörgHi,
Try this,
You may be able to workaround the problem by increasing free memory avaiable, parameter em/initial_size_MB (contact your Basis team or refer note 835474).
Also concenrate on parameter ztta/roll_extension (Refer note 146289)
Try increasing the parameter, abap/heap_area_dia from tcode RZ11.

Memory Consumption: Start A Petition!
I am using SQL Developer 4.0.0.13 Build MAIN 13.80. I was praying that SQL Developer 4.0 would no longer use so much memory and, when doing so, slow to a crawl. But that is not the case.
Is there a way to start a "petition" to have the SQL Development team focus on the products memory usage? This is problem has been there for years now with many posts and no real answer.
If there isn't a place to start a "petition" let's do something here that Oracle will respond to.
Thank youYes, at this point (after restarting) SQL Developer is functioning fine. Windows reports 1+ GB of free memory. I have 3 worksheets open all connected to two different DB connections. Each worksheet has 1 to 3 pinned query results. My problem is that after working in SQL Developer for a a day or so with perhaps 10 worksheets open across 3 database connections and having queried large data sets and performing large exports it becomes unresponsive even after closing worksheets. It appears like it does not clean up after itself to me.
I will use Java VisualVM to compare memory consumption and see if it reports that SQL Developer is releasing memory but in the end I don't care about that. I just need a responsive SQL Developer and if I need to close some worksheets at times I can understand doing so but at this time that does not help.
