Solaris 10 scales to....

A single instance of the Sparc Solaris 10 OS scales to....
How many processors?
How much memory?
A single instance of the x86 Solaris 10 OS scales to...
How many processors?
How much memory?
I've been searching all over, and unable to find these upper limits. If anyone knows, it would be greatly appreciated.

About the only way I can answer this is to quote the biggest machines of each variety that are available on the market.
The largest SPARC machine that Sun sells is a 72 processor (with 2 threads per processor) E25K with a max 576GB memory. Fujitsu sells a machine (PrimePower 2500) with up to 128 processors and 512GB memory.
The largest x86 machine that Sun sells takes up to 4 dual core processors with 32GB memory. (v40z).
As far as I know, this isn't the upper limit of Solaris scalability. It's just the upper limit of the hardware Sun has built and sold so far.

Need Facts about Solaris

I am trying to get the mail server moved to Solaris from NT. With the upgrade to 5.2 the office is wanting to move to 2000.
I need to know some facts to sell Solaris. Are there any places where NT/2000 would be lagging to Solaris with functions of the mail server? I need facts with this not rumors. What are your experinces with running 2000 to Solaris?
Thanks in advance

To add the list
Solaris is a true 64 bit OS/ HW platform. microsoft has yet to break that barrier.
Solaris scales to more cpus and memory than any flavor of windows
Like any other flavor of Unix Solaris has much better muti-threading/tasking ability
Keep in mind jumping from the world of M$ into Sun does require a significant learning curve. If you are unable to justify your reasons for wanting to go to solaris I tend to wonder if you have ever worked with a *nix type OS. This is not meant to be an insult just an observation. Remember if you do not have the skillset and make the switch and things go wrong remember whos butt is on the line ;-)

How to scale an nsapi app on Solaris SMP machines?

A Solaris nsapi application does not scale well on multi-processor (SMP) machines due to serialized heap allocation. What are the options to overcome this in an nsapi application?
We use SmartHeap from Microquill in our non-nsapi applications, but have not been able use it from our nsapi application (which we don't link). Has anyone had any success using SmartHeap or a similar product from an nsapi application?
Explicitly using the nsapi heap allocation macros is probably not an option for us.
Thanks
Norrie

Using the NSAPI pool allocator functions (e.g. pool_malloc) will give you the best possible performance, followed closely by the NSAPI pool allocator macros (e.g. MALLOC).
You can use SmartHeap from an NSAPI application - in fact, iWS 6.0 on Solaris bundles SmartHeap - but there are interoperability issues with Solaris JVMs. As a result, the server may crash when using SmartHeap with a Java-enabled iWS installation.

Oracle 9 for Solaris (Intel) x86?

Did oracle drop support for Solaris (Intel) x86? I run a shop with a large scale intel server running Solaris 9 (x86) and would like to try out Oracle 9i on it.
Please advise: [email protected]
Thanks!

Installing Adobe Type 1 Fonts on Solaris

We want to install ocra fonts on a workstation running Solaris 10. Currently the fonts are installed in a Solaris 8 server in:
/usr/openwin/lib/X11/fonts/Type1
On the workstation, we ftp'd the files from the server to /tmp on the workstation. We ran /usr/dt/bin/sdtfontadm and tried to use it to install the fonts. When you select install, 'Go To' /tmp and click 'Choose,'
we get a segmentation core dump. We have called this into Sun as a separate issue.
So we tried the manual way as described in IDAutomation.com (Installing Fonts on UNIX for Oracle Reports) and Oracle (Doc ID: 171464.1)
Both are pretty much the same. The following are the instructions:
1) copy ocra.pfa to /usr/openwin/lib/X11/fonts/Type1/outline
2) chown root:bin; chmod 644
3) Create a link of the file to /usr/openwin/lib/X11/fonts/Type1
4) Edit fonts.scale and add 1 to the number on top of the file.
5) add the following line:
ocra-pfa -adobe-ocra-medium-r-normal--0-0-0-0-p-0-iso8859-1
6) Run: /usr/openwin/bin/mkfontdir
7) Run: /usr/openwin/bin/xset fp rehash
8) Verify the font installation using /usr/dt/bin/sdtfontadm
When we run step 8, the font is there but the example tesxt is not OCR but courier.
We tried reformatting the workstation (due to the core dump) and setting it up to default to en_iso8859-1.
Can anyone help with this?
Thanks!

Windows Type 1 fonts each consist of two files, a .pfb file containing the font itself and a .pfm file containing extended font metrics used for formatting text on the host computer. If you don't have both files for a particular font, the font is uninstallable and unusable. To install a Type 1 font on a Windows system, the .pfb and .pfm for the font should be in the same directory. Right click on the font and click on Install or Install as shortcut. Install copies the two files to the \Windows\Fonts directory and subsequently uses the font from that location. Install as shortcut uses the font from the location the files are currently located in with the caveat that you must keep those files in that location or else the fonts will no longer be accessible.
If you actually attempted to install Adobe Type Manager on 32-bit Windows 7 (or later) system, you may have destroyed your system's ability to properly install and use Type 1 fonts at all. If this has happened, you may need to reinstall Windows! (If I recall correctly, the installer for ATM refuses to run at all on Windows 64-bit versions, sparing you the destruction of your Type 1 rendering!)

well, oracle's path seems to see 10g's version of the listener:

Any bad side-effects to lengthy blocking in native code? (Win32,Linux,Solar

1) Are there any negative side-effects to having one (or maybe a few) Java threads block for an extended period (e.g. hours) in native code? Naturally the thread would NOT be one of the "special" threads (such as the Swing event dispatcher, etc).
2) Does the answer vary by platform? I'm interested in Win32, Linux and possibly Solaris (in that order).
3) What if I scale the number of threads blocked in JNI code up to 100 threads. Does that change any of the answers? This is perhaps a silly number, I'm just trying to understand if more resources are consumed by blocking in the JNI as opposed to blocking in Java.
4) Do modern JVM's use one native thread per Java thread? If so, then I would guess there is really nothing special about blocking in native code.
Motivation for query -- In my application I need to interface with legacy C++ code that blocks (mostly on socket and i/o selects). I'm not thrilled about native code, but if there are no serious side-effects to extended blocking, it may be a viable approach.

1) Are there any negative side-effects to having one
(or maybe a few) Java threads block for an extended
period (e.g. hours) in native code? Naturally the
thread would NOT be one of the "special" threads (such
as the Swing event dispatcher, etc).As far as I know the native code is loaded dynamic when a thread will use it.
So if the thread 1 needs the code written in the native.dll the thread 1 will use
the first instance of native.dll. So let's say this is blocked.
Then after 2 hours another thread called thread2 calls the native.dll code. Then
java ask the OS to create another instance of the native.dll and so on.
So now there are 2 threads and 2 instances of the dll in the memory.
All these apply to the Win32 OSs.

If your machine could suffer 100 pure java threads then it is not a problem to be some of them JNI ones.

Solaris Kernel and TCP/IP Tuning Parameters (Continued)

This page describes some configuration optimizations for Solaris hosts running ATG Page Serving instances (application servers) that will increase server efficiency.
Note that these changes are specific to Solaris systems running ATG application servers (+page serving+ instances). Do not use these on a web server or database server. Those systems require entirely different settings.
h3. Solaris 10 Kernel
Adjust /etc/system (parameters below) and reboot the system.

h4. Increase the connection hash table size
{color:blue}set tcp:tcp_conn_hash_size=8192{color}
Increase the connection hash table size to make look-up's more efficient. The connection hash table size can be set only once, at boot time.
[http://download.oracle.com/docs/cd/E19455-01/816-0607/chapter4-63/index.html]
h4. Increase maximum shared memory segment size
{color:blue}set shmsys:shminfo_shmmax=4294967295{color}
Increase the maximum size of a system V shared memory segment that can be created from roughly 8MB to 4GB.
This provides an adequate ceiling; it does not imply that shared memory segments of this size will be created.
[http://download.oracle.com/docs/cd/E19683-01/816-7137/chapter2-74/index.html]
h4. Increase memory allocated for dirty pages
{color:blue}set autoup=900{color}
Increase the amount of memory examined for dirty pages in each invocation and frequency of file system synchronizing operations.
The value of autoup is also used to control whether a buffer is written out from the free list. Buffers marked with the B_DELWRI flag (which identifies file content pages that have changed) are written out whenever the buffer has been on the list for longer than autoup seconds. Increasing the value of autoup keeps the buffers in memory for a longer time.

h3. TCP
ndd -set /dev/tcp tcp_time_wait_interval 60000
ndd -set /dev/tcp tcp_conn_req_max_q 16384
ndd -set /dev/tcp tcp_conn_req_max_q0 16384
ndd -set /dev/tcp tcp_ip_abort_interval 60000
ndd -set /dev/tcp tcp_keepalive_interval 7200000
ndd -set /dev/tcp tcp_rexmit_interval_initial 4000
ndd -set /dev/tcp tcp_rexmit_interval_max 10000
ndd -set /dev/tcp tcp_rexmit_interval_min 3000
ndd -set /dev/tcp tcp_smallest_anon_port 32768
ndd -set /dev/tcp tcp_xmit_hiwat 131072
ndd -set /dev/tcp tcp_recv_hiwat 131072
ndd -set /dev/tcp tcp_naglim_def 1h4. Tuning the Time Wait Interval and TCP Connection Hash Table Size
{color:blue}/usr/sbin/ndd -set /dev/tcp tcp_time_wait_interval 60000{color}
The tcp_time_wait_interval is how long a connection stays in the TIME_WAIT state after it has been closed (default value 240000 ms or 4 minutes). With the default setting, this socket will remain for 4 minutes after you have closed the FTP connection. This is normal operating behavior. It is done to ensure that any slow packets on the network will arrive before the socket is completely shutdown. As a result, a future program that uses the same socket number won't get confused upon receipt of packets that were intended for the previous program.
On a busy Web server a large backlog of connections waiting to close could build up and the kernel can become inefficient in locating an available TCP data structure. Therefore it is recommended to change this value to 60000 ms or 1 minute.
h4. Tuning the maximum number of requests per IP address per port
{color:blue}ndd -set /dev/tcp tcp_conn_req_max_q 16384{color}
{color:blue}ndd -set /dev/tcp tcp_conn_req_max_q0 16384{color}
The {color:blue}tcp_conn_req_max_q{color} and {color:blue}tcp_conn_req_max_q0{color} parameters are associated with the maximum number of requests that can be accepted per IP address per port. tcp_conn_req_max_q is the maximum number of incoming connections that can be accepted on a port. tcp_conn_req_max_q0 is the maximum number of “half-open” TCP connections that can exist for a port. The parameters are separated in order to allow the administrator to have a mechanism to block SYN segment denial of service attacks on Solaris.
The default values are be too low for a non-trivial web server, messaging server or directory server installation or any server that expects more than 128 concurrent accepts or 4096 concurrent half-opens. Since the ATG application servers are behind a DMZ firewall, we needn't starve these values to ensure against DOS attack.
h4. Tuning the total retransmission timeout value
{color:blue}ndd -set /dev/tcp tcp_ip_abort_interval 60000{color}
{color:blue}tcp_ip_abort_interval{color} specifies the default total retransmission timeout value for a TCP connection. For a given TCP connection, if TCP has been retransmitting for tcp_ip_abort_interval period of time and it has not received any acknowledgment from the other endpoint during this period, TCP closes this connection.
h4. Tuning the Keep Alive interval value
{color:blue}ndd -set /dev/tcp tcp_keepalive_interval 7200000{color}
{color:blue}tcp_keepalive_interval{color} sets a probe interval that is first sent out after a TCP connection is idle on a system-wide basis.
If SO_KEEPALIVE is enabled for a socket, the first keep-alive probe is sent out after a TCP connection is idle for two hours, the default value of the {color:blue}tcp_keepalive_interval{color} parameter. If the peer does not respond to the probe after eight minutes, the TCP connection is aborted.
The {color:blue}tcp_rexmit_interval_*{color} values set the initial, minimum, and maximum retransmission timeout (RTO) values for a TCP connections, in milliseconds.
h4. Tuning the TCP Window Size
{color:blue}/usr/sbin/ndd -set /dev/tcp tcp_xmit_hiwat 65535{color}
{color:blue}/usr/sbin/ndd -set /dev/tcp tcp_recv_hiwat 65535{color}
Setting these two parameters controls the transmit buffer and receive window. We are tuning the kernel to set each window to 65535 bytes. If you set it to 65536 bytes (64K bytes) or more with Solaris 2.6, you trigger the TCP window scale option (RFC1323).
h4. Tuning TCP Slow Start
{color:blue}/usr/sinb/ndd -set /dev/tcp tcp_slow_start_initial 4{color}
tcp_slow_start_initial is the number of packets initially sent until acknowledgment, the congestion window limit.
h4. Tuning the default bytes to buffer
{color:blue}ndd -set /dev/tcp tcp_naglim_def 1{color}
{color:blue}tcp_naglim_def{color} is the default number of bytes to buffer. Each connection has its own copy of this value, which is set to the minimum of the MSS for the connection and the default value. When the application sets the TCP_NODELAY socket option, it changes the connection's copy of this value to 1. The idea behind this algorithm is to reduce the number of small packets transmitted across the wire by introducing a short (100ms) delay for packets smaller than some minimum.
Changing the value of tcp_naglim_def to 1 will have the same effect (on connections established after the change) as if each application set the TCP_NODELAY option.
{note}
The current value of any of the TCP parameters can be displayed with the command ndd get. So to retrieve the current setting of the {color:blue}tcp_naglim_def parameter{color}, simply execute the command:\\
{color:blue}ndd -get /dev/tcp tcp_naglim_def{color}

want to what TCP parameter this option corresponds in
the underlying TCP connection.This doesn't correspond to anything in the connection, it is an attribute of the API.
The same questions
arises fro other options from SocketOptions class.setTcpNoDelay() controls the Nagle algorithm. set{Send,Receive}BufferSize() controls the local socket buffers.

Fonts in Solaris/Exceed/X-window(Maby standard fonts?)

Hey
I use Styled document where i set the font family to "Arial" and the size to 2*Scale(Scale = 1-10)
when running this in windowsit works well, but on the Solaris/Exceed/X-window it dont. It have the same size all the time!
Probely it is not even using "Arial".
Is ther any standard fonts that i can scale?
I have look in the Xconfig of the hummingbird/Exceed program and then fonts. there i find fonts like
font db file
100dpi
latin1
andrew
and so on
if i dubbel klick on one of them i get a list of fonts in diffrent sizes like this
carb08
carb10
carb12
carb14
and so on.
How could i solve my problem? shold i just choose a name like carb10 and switch it with the "Arial" in the code? and can i scale this fonts or do i have to choose the right font size to?
//SnowJim

Yes that would be great, but i am not able to install fonts on the solaris machine.
Is there no other way? i dont have to use the sam font as in Windows, but a font that is scale able and as Arial as posible.

Weblogic 5.1 sp3 with Apache or Stronghold on Solaris 2,7

Hi All,
We are planning to use Apache or Stronghold(most probably Stronghold as it
supports SSL which I was told Apache does not support) and WebLogic 5.1 sp
3. Has anyone used this combination before if so we would like to know if
you have faced any integration issues with this ? If you do what kind of
integration issues were they ? Just connection related or scalability
related ? Has anyone used WebLogic built-in webservevr in production
environment ? How does it scale up ?
Thanks
Prasad

Would you please let me know when exactly(date) the sp4 was released

3. mod_wl_ssl_raven.so for Apache + Raven installations
mod_wl_ssl_raven.so was required because Raven applies frontpage patches which

On Solaris there are no problems integrating weblogic and Apache.
I would not recommend using the weblogic web server, the performance of image
streaming and serving static webpages is not the greatest - apache will do a
much better job for you.
Weblogic also has a plug in for apache on Solaris that supports fail over. ie.
if one of your weblogic server goes down then apache can reconnect to another
one

BerkeleyDB cache size and Solaris

I am having problems trying to scale up an application that uses BerkelyDB-4.4.20 on Sun Sparc servers running Solaris 8 and 9.
The application has 11 primary databases and 7 secondary databases.
In different instances of the application, the size of the largest pimary database
ranges only from 2MB to 10MB, but those will grow rapidly over the
course of the semester.
The servers have 4-8 GB of RAM and 12-20 GBytes of swap.
Succinctly, when the primary databases are small, the application runs as expected.
But as the primary databases grow, the following, counterintuitive phenomenon
occurs. With modest cache sizes, the application starts up, but throws
std::exceptions of "not enough space" when it attempts to delete records
via a cursor. The application also crashes randomly returning
RUN_RECOVERY. But when the cache size is increased, the application
will not even start up; instead, it fails and throws std::exceptions which say there
is insufficient space to open the primary databases.
Here is some data from a server that has 4GB RAM with 2.8 GBytes free
(according to "top") when the data was collected:
DB_CONFIG............db_stat -m.................................Result
set_cachesize........Pool......Ind. Cache
0 67108864 1.........80 MB.......8 KB................Starts but crashes and can't delete by
.....................................................................cursor because of insufficient space
0 134217728 1.......160 MB......8 KB.................Same as case above
0 268435456 1........320 MB.....8 KB.................Doesn't start and says there is
......................................................................not enough space to open a primary
......................................................................database.
0 536870912 1.........512 MB...16 KB.................Doesn't start and says there is
......................................................................not enough space to open a primary
......................................................................database (although it mentions a
......................................................................different primary database than before.
1 073741884 1........1GB 70MB....36 KB............Doesn't start and says there is
......................................................................not enough space to open a primary
......................................................................database (although it mentions a
......................................................................different pimary database than
......................................................................previously).
2 147483648 1.........2GB 140MB...672 KB........Doesn't start and says there is
......................................................................not enough space to open a primary
......................................................................database (although it mentions a
......................................................................different pimary database than
......................................................................previously).
I should also mention that the application is written in Perl and uses
the Sleepycat::Db Perl module to interface with the BerkeleyDB C++ API.
Any help on how to interpret this data and, if the problem is the
interface with Solaris, how to tweak that, will be greatly appreciated.
Sincerely,
Bill Wheeler, Department of Mathematics, Indiana University, Bloomington.

Having found answers to my questions, I think I should document them here.
1. On the matter of the error message "not enough space", this message
apparently orginates from Solaris. When a process (e.g., an Apache child)
requests additional (virtual) memory (via either brk or mmap) such that the
total (virtual) memory allocated to the process would exceed the system limit
(set by the setrlimit command), then the Solaris kernel rejects the request
and returns the error ENOMEM . Somewhat cryptically, the text for this error
is "not enough space" (in contrast, for instance, to "not enough virtual
memory").
Apparently, when the BerkeleyDB cache size is set too large, a process
(e.g., an Apache child) that attempts to open the environment and databases
may request a total memory allocation that exceeds the system limit.
Then Solaris will reject the request and return the ENOMEM error.
Within Solaris, the only solutions are apparently
(i) to decrease the cache size or
(ii) to increase the system limit via the setrlimit command.
2. On the matter of the DB_RUNRECOVERY errors, the cause appears
to have been the use of the DB_TXN_NOWAIT flag in combination with
code that was mishandling some of the resulting, complex situations.
Sincerely,
Bill Wheeler

Very-large-scale searching in J2EE

I'm looking to solve a very-large-scale searching problem. I am creating a site
where users can search a table with five million records, filtering and sorting
independantly on ten different columns. For example, the table might be five million
customers, and the user might choose "S*" for the last name, and sort ascending
on street name.
I have read up on a number of patterns to solve this problem, but anticipate some
performance issues. I'll explain below:
1) "Page-by-Page Iterator" or "Value List Handler"
In this pattern, it appears that all records that match the search criteria are
retrieved from the database and cached on the application server. The client (JSP)
can then access small pieces of the cached results at a time. Issues with this
include:
- If the customer record is 1KB, then wide search criteria (i.e. last name =
S*) will cause 1 GB transfer from the database server to app server, and then
1GB being stored on the app server, cached, waiting for the user (each user!)
to ask for the next 10 or 100 records. This is inefficient use of network and
memory resources.
- 99% of the data transfered from the database server will not by used ... most
users flip through a couple of pages and then choose a record or start a new search
2) Requery the database each time and ask for a subset
I haven't seen this formalized into a pattern yet, but the basic idea is this:
If a clients asks for records 1-100 first (i.e. page 1), only fetch that many
records from the db. If the user asks for the next page, requery the database
and use the JDBC API's ResultSet.absolute(int row) to start at record 101. Issue:
The query is re-performed, causing the Oracle server to do another costly "execute"
(bad on 5M records with sorting).
To solve this, I've beed trying to enhance the second strategy above by caching
the ResultSet object in a stateful session bean. Unfortunately, this causes a
"ResultSet already closed" SQLException, although I ensure that the Connection,
PreparedStatement, and ResultSet are all stored in the EJB and not closed. I've
seen this on newsgroups ... it appears that WebLogic is forcing the Connection
closed. If this is how J2EE and pooled connections work, then that's fine ...
there's nothing I can really do about it.
Another idea is to use "explicit cursors" in Oracle. I haven't fully explored
it yet, but it wouldn't be a great solution as it would be using Oracle-specific
functionality (we are trying to be db-agnostic).
More information:
- BEA WebLogic Server 8.1
- JDBC: Oracle's thin driver provided with WLS 8.1
- Platform: Sun Solaris 5.8
- Oracle 9i
Any other ideas on how I can solve this issue?

Any other ideas on how I can solve this issue? Hi. Fancy SQL to the rescue! If the table has a unique key, you can simply send a
query per page, with iterative SQL that selects the next N rows beyond what was
selected last time. Eg:
Let variable X be the highest key value you've seen so far. Initially it would
be the lowest possible value.
select * from mytable M
where ... -- application-specific qualifications...
and M.key >= X
and (100 <= select count(*) from mytable MM where MM.key > X and MM.key < M.key and ...)
In English, this says, select all the qualifying rows higher than what I last saw, but
only those that have fewer than 100 qualifying rows between the last I saw and them (ie:
the next 100).
When processing this query, remember the highest key value you see, and use it for the
next query.

Solaris WEB SERVER?

Hi all;
I have installed solaris x86 on my home machine works well...
Now i want to change my rental dedicated server from windows to solaris web server?i dont have any idea about it?is it logical,stable and advantageous to use solaris x86 as a web server...
i will use apache,tomcat,mysql on it,webmin control panel,remote desktop to server,mail server etc...the OS must support all of them...and must have support on internet forums...
which OS you advice to me..?solaris or freebsd or linux versions?
thank you
Burak

You know, asking what nx dialect you should use in a Solaris forum is sort of daring.
All of the softwares you listed works on Solaris, with the possible exeption of remote desktop, which is a windows product used for windows servers. On the otherhand nx has several alternatives to remote desktops, and being unix, they don't really need one anyway.
In general i think its a bad idea to ask people what you should run on your server, there are a lot of religous people out here, and everyone will claim that their unix dialect is the best in every possible way, and that everyone who disagrees with them are either lame, stupid, managers or all of it.
This actually gets quite entertaining when it comes to Linux, since different groups will also argue that THEIR Linux is the only usable and that everything else is crap.
Anyway.
My advice is that you look on what features you want, which platform you feel most comfortable with and what you want to be able to do. Solaris for one thing can be very heavily loaded, scales extremeny well and comes with tons of nice features like Zones, which is a good thing if you have many IP addresses and don't want different webservers to be in the same zone.
