Cache Size on RD240 300 Gb Drives Part# 67Y1481
Can't seem to find the Cache / Buffer size on these drives. It' not listed in the tech specs I have located so far.
Anyone know where I could find this?
Thanks
Solved!
Go to Solution.
In case it is of assistance to someone else in the future, the 300 Gb SAS 6Gb part# 67Y1481 for the RD240 are Seagate Cheetah 15k.7 ST3300657SS. These are 16Mb cache drives but rate faster than the Hitachi 64Mb cache units.
Does anyone know if the drive caddy can be purchased separately anywhere other than IBM? They are backordered for 2+ months and I have a pile of these drives that I could use in an RD240 I have in stock.
Thanks

Default Adobe Drive cache size is only 128MB
The Adobe Drive cache size defaults to 128MB. This doesn't seem a very logical value as a single file may be easily larger than that. Is there a reason it's so small? As most users would probably benefit from a larger cache size and today's harddrives should also allow a larger cache size.
Would it make sense to have a default cache size of 5-10GB? Maybe depending on the amount of free disk space available during installation?Hello.
To help automatically clear up some cache from Firefox, click on each of the images from left to right. Now at least you won't have to constantly do it yourself.
Also, to help you with your space issues, download Clean Master from the Google Play app Store: https://play.google.com/store/apps/details?id=com.cleanmaster.mguard this app will clean up hidden cache and useless files on your phone, helping free up space.
And as for why Firefox keeps reverting to the default cache in "about:config", I do not know. We are sorry for any inconveniences that this has caused you. But please try doing what was mentioned above to help with your issue.
Hope this helps! -
Java.sql.SQLException: Statement cache size has not been set
All,
I am trying to create a light weight SQL Layer.It uses JDBC to connect to the database via weblogic. When my application tries to connect to the database using JDBC alone (outside of weblogic) everything works fine. But when the application tries to go via weblogic I am able to run the Statement objects successfully but when I try to run PreparedStatements I get the following error:
java.sql.SQLException: Statement cache size has not been set

i have checked the StatementCacheSize and it is 10. Is there any other setting that needs to be implemented for this to work? Has anybody seen this error before? Any help will be greatly appreciated.

Question of Berkeley DB "cache size"
quote:
Set the size of the shared memory buffer pool, that is, the size of the cache.
The cache should be the size of the normal working data set of the application, with some small amount of additional memory for unusual situations. (Note: the working set is not the same as the number of pages accessed simultaneously, and is usually much larger.)
The default cache size is 256KB, and may not be specified as less than 20KB. Any cache size less than 500MB is automatically increased by 25% to account for buffer pool overhead; cache sizes larger than 500MB are used as specified. The current maximum size of a single cache is 4GB. (All sizes are in powers-of-two, that is, 256KB is 2^18 not 256,000.)
The database environment's cache size may also be set using the environment's DB_CONFIG file. The syntax of the entry in that file is a single line with the string "set_cachesize", one or more whitespace characters, and the cache size specified in three parts: the gigabytes of cache, the additional bytes of cache, and the number of caches, also separated by whitespace characters. For example, "set_cachesize 2 524288000 3" would create a 2.5GB logical cache, split between three physical caches. Because the DB_CONFIG file is read when the database environment is opened, it will silently overrule configuration done before that time.
This method configures a database environment, including all threads of control accessing the database environment, not only the operations performed using a specified Environment handle.
This method may not be called after the environment has been opened. If joining an existing database environment, any information specified to this method will be ignored.
This method may be called at any time during the life of the application.
Parameters:
cacheSize The size of the shared memory buffer pool, that is, the size of the cache.
The question:
When I have a host, the memory total is 16G.
I don't know what mean of this document.
How many max cache size can be set ?
4G? 16G?
or cacheCount (4)* 4G = 16G?
My Email: [email protected]What version of Berkeley DB are you using?
I'm a little confused about what you are quoting. Most of your quote seems to be from DB_ENV->set_cachesize(), but set_cachesize does not have a parameter named cacheSize. The parameters for set_cachesize are gbytes, bytes and ncache.
You use set_cachesize to specify the logical cache that you can optionally split into more than one physical region. The maximum size of the logical cache is 4GB and there is only one logical cache. You specify the total size of the logical cache with the gbytes and bytes parameters. If you set ncache to a value greater than 1, you split this logical cache into separate physical regions. So, for example, if you specify (gbytes=2, bytes=0, ncache=1) you will have a logical cache of 2GB that internally is split into 2 separate physical regions of 1GB each.
You can read more about the memory pool cache in the Reference Guide sections "Selecting a cache size" and "Configuring the memory pool".
If you have other Berkeley DB questions that are not specific to replication, you should direct them to the general Berkeley DB forum where you will have the benefit of a wider set of Berkeley DB experts:

as per the question, tried to up the cache from 75meg to 300meg but it resets after i restart firefox, have tried to change to various cache sizes but to no avail.
-=EDIT=-
it must be something to do with the profile, as when i set up a new profile in the manager, the cache size problem no longer appears. but now, how to repair my profileok, nothing in that text file helped but the original file that it was based on pointed me in the direction that it might be an extension. The only extensions i have are NoScript and FasterFox Lite version....
I have now traced the fault to lie with FasterFox... if you are not familiar with fasterfox it speeds up internet connections in firefox... several of the options are presets... but when i selected custom it gave me the option of a cache setting, which was set to 75megs.
I have now changed that cache setting in fasterfox to 300 Megs and it is now persistant in firefox on restart.
hopefully this information will be helpful to other people in the future that suffer the same problem.
Thanks for your help TonyE, its greatly appreciated -
Hi all,
while using some dinamyc store procedures I get in the following error:
[BEA][SQLServer JDBC Driver]Value can not be converted to requested type.
I'm using WL8.1 and Sql Server 2000.
Store procedure contains two different queries where table name is a store procedure's
parameter.
The first time it works great, after that I always have this error:
Reading bea doc's I found
There may be other issues related to caching prepared statements that are not
listed here. If you see errors in your system related to prepared statements,
you should set the prepared statement cache size to 0, which turns off prepared
statement caching, to test if the problem is caused by caching prepared statements.
If I set prepared statement cache size to 0 everything works great but that does
not seem the better way.
Should we expect Bea to solve this problem?
Or whatever else solution?
such as using JDBCConnectionPoolMBean.setPreparedStatementCacheSize()
dynamically ?
thks in advance
Leonardocaching works well for DML and thats what it is supposed to do. But it looks
like you are doing DDL , which means your tables might be getting
created/dropped/altered which effectively invalidates the cache. So you
should try to turn the cache off.

How do I Change the Cache size?
I have an iBook G4 and am trying to change the cache size for this screen saver I downloaded.
iBook G4 Mac OS X (10.4.9)Hi
Curious which screensaver you are referring to?
Screensavers can be processor intensive, requiring a certain level of computing power to avoid flicker or stuttering. The G4 iBook is not that type of machine.
Some Screen Savers have a preference file (accessed through the Desktop and Screen Saver System Pref Panel - highlight the saver, and select "options" if one is available) where you can adjust the operating speeds and other parameters. Otherwise, I don't believe there is anything more you can do.
I notice a big difference in certain screen savers running on my G5 iMac vs. my iBook, with the former handling the screen movement much more easily.

New FAQ Entry on JVM Parameters for Large Cache Sizes
I've posted a new [FAQ entry|http://www.oracle.com/technology/products/berkeley-db/faq/je_faq.html#60] on JVM parameters for large cache sizes. The text of it is as follows:
What JVM parameters should I consider when tuning an application with a large cache size?
If your application has a large cache size, tuning the Java GC may be necessary. You will almost certainly be using a 64b JVM (i.e. -d64), the -server option, and setting your heap and stack sizes with -Xmx and -Xms. Be sure that you don't set the cache size too close to the heap size so that your application has plenty of room for its data and to avoided excessive full GC's. We have found that the Concurrent Mark Sweep GC is generally the best in this environment since it yields more predictable GC results. This can be enabled with -XX:+UseConcMarkSweepGC.
Best practices dictates that you disable System.gc() calls with -XX:-DisableExplicitGC.
Other JVM options which may prove useful are -XX:NewSize (start with 512m or 1024m as a value), -XX:MaxNewSize (try 1024m as a value), and -XX:CMSInitiatingOccupancyFraction=55. NewSize is typically tuned in relationship to the overall heap size so if you specify this parameter you will also need to provide a -Xmx value. A convenient way of specifying this in relative terms is to use -XX:NewRatio. The values we've suggested are only starting points. The actual values will vary depending on the runtime characteristics of the application.
You may also want to refer to the following articles:
* Java SE 6 HotSpot Virtual Machine Garbage Collection Tuning
* The most complete list of -XX options for Java 6 JVM
* My Favorite Hotspot JVM Flags
Edited by: Charles Lamb on Oct 22, 2009 9:13 AMFirst of all please be aware HSODBC V10 has been desupported and DG4ODBC should be used instead.
The root cause the problem you describe could be related to a timeout of the ODBC driver (especially while taking care of the comment: it happens only for larger tables):
(0) [MySQL][ODBC 3.51 Driver]MySQL server has gone away (SQL State: S1T00; SQL
(0) Code: 2006)
indicates the Driver or the DB abends the connection due to a timeout.
Check out the wait_timeout mysql variable on the server and increase it. -
(statement cache size = 0) == clear statement cache ?
Hi
I ran this test with WLS 8.1. I set to the cache size to 5, and I call a servlet
which invokes a stored procedure to get the statement cached. I then recompile
the proc, set the statement cache size to 0 and re-execute the servlet.
The result is:
java.sql.SQLException: ORA-04068: existing state of packages has been discarded
ORA-04061: existing state of package "CCDB_APPS.MSSG_PROCS" has been invalidated
ORA-04065: not executed, altered or dropped package "CCDB_APPS.MSSG_PROCS"
ORA-06508: PL/SQL: could not find program unit being called
ORA-06512: at line 1
which seems to suggest even though the cache size has set to 0, previously cached
statements are not cleared.

Open two sqlplus sessions. In one, execute the package.
Then, in the other, drop and recreate that package. Then, go
to the previous window and execute that same package. You
will get that error. Now, in that same sqlplus session,
execute that same line one more time and it goes through. In
short, in your above test, execute your servlet twice and I
bet on the second execution you have no issue.Hi. We did some testing offline, and verified that even a
standalone java program: 1 - making and executing a prepared
statement (calling the procedure), 2 - waiting while the
procedure gets recompiled, 3 - re-executing the prepared
statement gets the exception, BUT ALSO, 4 - closing the
statement after the failure, and making a new identical
statement, and executing it will also get the exception! JoeI just had the chance to test this within weblogic and not just
sqlplus.Note, I wasn't using SQL-PLUS, I wrote a standalone program
using Oracle's driver...
MY SCENARIO:
I had one connection only in my pool. I executed a package.
Then, went into the database and recompiled that package. Next
execution from app found this error. I then subsequently
executed the same package from the app and it was successful.And this was with the cache turned off, correct?
What the application needs to do is catch that error and within
the same connection, resubmit the execution request. All
connections within the pool will get invalidated for that
package's execution.Have you tried this? Did you try to re-use the statement you had,
or did you make a new one?
Maybe Weblogic could understand this and behave this way for
Oracle connections?It's not likely that we will be intercepting all exceptions
coming from a DBMS driver to find out whether it's a particular
failure, and then know that we can/must clear the statement cache.
Note also that even if we did, as I described, the test program I
ran did try to make a new statement to replace the one that
failed, and the new statement also failed.
In your case, you don't even have a cache. Would you verify
in your code, what sort of inline retry works for you?

Why can't I increase the cache size in FF 4?
OK, first of all, to be honest I really don't like FF 4. I see absolutely no advantages over the previous versions and I can't find anything to like about FF 4..
One big and annoying factor (besides the how UI and layout) is why can't I increase the cache size?
If I choose to manage it myself and override what the developers did, I can go to 1024 and that's it. If I want 5GB of cache, I'm out of luck because some coded decides how I want to manage my disk space? They're kidding, right?
What the heck is the matter with these guys?
This thing is so bad that I've resisted upgrading, I didn't have a choice when I upgraded to Ubuntu 11.04, it came with the package.. Yuk... I've been a FF user since late 2003 or early 2004... I'm about to part ways with this thing if they don't fix it...Even IE sucks less than this thing....
None of my Windows machines are going to get 4 loaded if I can help it.. About 1 million people agree with me...correction.. It's not a million.. it's legion at this point..
Google "I hate FF 4" and you'll get 40,900,000 results... I don't trust Google further than I can throw them, but 41 million people complaining about this thing? What a freakin travesty... -
Dynamically changing SCCM Cache Size
Has anyone come up with a 'clean' method to increase the SCCM Cache size as part of a large application deployment?
For example, we have a 8GB adobe application that is larger than our default client cache size - 5GB. We have made the switch to all SSDs, so preserving disk space is a necessity.
The option of increasing the cache on all clients is not appetizing. We attempted to make a dependance on another application that will increase the cache size, but the client will not run the dependency if the size of the first application is larger than
the cache.
We COULD run the application as part of a task sequence, but this would mean our software portal users would need to know to shop for a task sequence rather than software for these few applications that exceed cache size.
Anyone come up with a better solution for this?
Will
WillJorgen,
Many of our users are over remote WAN links, and we use 1e Nomad to alleviate network contention. Doing as you suggested would work, once - then my network administrators would kill me.
We have made the strategic decision to try and avoid the use of packages, but this may have to fall into the ugly 'exception' bucket. Unfortunately doing so would make it unavailable during OSD. (We are using a MDT BCD integrated task sequence.. there is
no good way to do 2 packages and then 2 application and then a package and then an application so we just cut the cord and said anything in OSD has to be an application used by the coalescedApplications variable)...
But appreciate the thought.

Proxy 4 - Cache size keeps growing
I may have a wrong cache setting somewhere, but I can't find it. I am running Proxy 4.0.2 (for windows).
Under Cache settings, I have "Cache Size" set to 800MB. Under "Cache Capacity" I have it set to 1GB (500 MB-2GB).
The problem is my physical cache size on the hard drive keeps growing and growing and is starting to fill the partition on the hard drive. At last count, the "cache" directory on the hard drive which holds the cache files is now using 5.7GB of space and still growing.
Am I mis-understanding something? I thought the max physical size would be a lot lower, and stop at a given size. But the cache directory on the hard drive is now close to 6GB and still growing day by day. When is it going to stop growing, or how do I stop it and put a cap on the physical size it can grow to on the hard drive?
ThanksUntil 4.03 is out, you can use this script..
Warning: experimental, run this on a copy of cache first to make sure that it works as you want it.
The firs argument is the size in MB's that you want to remove.
I assume your cachedir is "./cache" if it is not, then change the variable $cachedir to
the correct value.
==============cut-here==========
#!/bin/perl
use strict;
use File::stat;
my $cachedir = "./cache";
my $gc_size; #bytes
my $verbose = 0;
sub gc_file {
my $file = shift;
my $sb = stat($file);
$gc_size -= $sb->size;
unlink $file;
print "$gc_size more after $file\n" if $verbose;
exit 0 if $gc_size < 0;
sub main {
my $size = shift;
$gc_size = $size * 1024 * 1024; #in MB's
opendir(DIR, $cachedir) || die "can't opendir $cachedir: $!";
my @sects = grep {/^s[0-9]\.[0-9]{2}$/} readdir(DIR);
closedir DIR;
foreach my $sect (@sects) {
chomp $sect;
opendir (CDIR, "$cachedir/$sect") || die "cant opendir $cachedir/$sect: $!";
my @ssects = grep {/^[A-F0-9]{2}$/} readdir(CDIR);
closedir CDIR;
foreach my $ssect (@ssects) {
chomp $ssect;
opendir (SCDIR, "$cachedir/$sect/$ssect") || die "cant opendir $cachedir/$sect/$ssect: $!";
my @files = grep {/^[A-Z0-9]{16}$/} readdir(SCDIR);
closedir SCDIR;
foreach my $file (@files) {
gc_file "$cachedir/$sect/$ssect/$file";
main $ARGV[0] if $ARGV[0];
=============cut-end==========On your second problem, the easiest way to recover a corrupted partition is to list out the sections in that partition, and delete those sections that seem like odd ones
eg:
$ls ./cache
s4.00 s4.01 s4.02 s4.03 s4.04 s4.05 s4.06 s4.07 s4.08 s4.09 s4.10 s4.11 s4.12 s4.13 s4.14 s4.15 s0.00
Here the s0.00 is the odd one out, so remove the s0.00 section. Also keep an eye on the relative sizes of the sections. if the section to be removed is larger than the rest of the sections combinde, you might not want to remove that.

Warning: Cache size set too large?
I've recently installed a SSD to work as a dedicated cache drive, and I've directed the 3 cache settings in AE (CS6) to it.
The drive is 240GB, but I can't put the cache size over 150GB without getting a warning that it's set too high. Is this true? Am I wasting almost 100GB?Use your drive for something else. 150GB is a huge huge cache. The CS6 disk cache is glitchy anyway. I have mine turned off most of the time.
