Optimal XP Configuration for Workshop

We've put Workshop 8.1 SP1 on WinXP Pro workstations (2.3GHZ, 1Gb RAM, 20Gb HD). We used them for our week of BEA Portal training. The performance was miserable - it took minutes for jsps to compile and open for debugging - and they locked up or crashed at least twice a day. After class, we upgraded to SP2 (we couldn't during class to avoid conflict with class examples) but have seen no appreciable difference in stability or performance. BEA provides "minimum" requirements (PIII 700Mhz, 1 Gb RAM), which we exceed. Before I go essentially sell my first born to get our PC guys to get me some newer PC hardware (we buy Dell OptiPlex as our corporate standard - can get 3.2GHz w/ 2Gb RAM), are there other tweaks which may help? I've received internal suggestions to possibly get the Dell Precision WinXP workstation to get:
* A bigger, faster disk (70 Gb, 7200rpm SATA) and create a much bigger swap file (15-20Gb).
* A dual proc XP box
But before we sink $3,500 into these, would this help my problem? Or is Workbench just slow and unreliable?

Mike,
Have you tried running with SP2 yet? You should notice perf
improvements with SP2.

Which is the optimal hard drive configuration for Logic Pro ?

hello people
i would like to ask your advices about possible hard drive configurations for Logic Pro
I have a Mac Pro and thinking to buy 4 x 500GB drives .
there are several combinations in my mind to configure , but first of all i would like to ask which is the best for an optimal system for Logic Pro
model 1 :
1 stripe Raid 0 array drive for ''System'' (500+500 = 1000)
1 stripe Raid 0 array drive for ''recording + sound banks'' (500 + 500 = 1000)
which means to using 4 hard drives as 2 drives
model 2 :
1 stripe Raid 0 array drive for ''System'' (500+500 = 1000)
1 Single drive for Sound banks (500)
1 Single drive for Recording (500)
which means to using 4 hard drives as 3 drives
Or , it is more healthy to use the drives as single , without raid , stripe sets but with its own capacity instead of combining .
and also if someone has an idea regarding to compare of Seagate and Westerndigital drives (which is the best for audio recording) , would be really helpfull
I am kinda rookie for these subjects :/
thanks in advance

heelo blayzay
thanks for the reply and assistance.
1) how can i create a back up set for the 4th HD to be make back up of the 2nd and 3rd HD
2) what about to make 1st HD for system and 2nd3rd4th (1.5TB) for audio recording, and an external drive for backups ?
For the back ups , is there a special process for the backing up HD (internal or external) ? Or should i just need a Clone software to make the back up
thank you again.

Optimal configurations for webobjects using Java Monitor

Can someone please let me know the optimal configurations for webobjects? We need details on the number of instances which can be created per cpu on the application server. Please also provide information on the thread configurations per instance in java monitor.

I do need the threads to communicate. The fact is that I simplified the thing just to understand better responses from you :). The real problem is more complicated. I have a arbitrary number of threads of two different classes. These threads have to access a shared resource (I used the boolean free). Moreover I have to give precedence to one of these two classes. So, I used to integers to represent two queues. The fact is that only the first thread to be ran reaches the end. The others, I saw, reach the wait() method, but then they stops and the program does not finish.
I mean that I thought this: the first thread to reach the wait() passes. Then, this first thread starts to use the resource (free becomes false). Every other thread which reach the while(...) stops there (there is the wait()). Then the first process, at a particular time, release the resource (free = true) and communicate this to another thread which was stuck at the wait() instruction (through the notify()). The problem I see is that every thread reach the wait() and stops there. After the first one is finished, no more... The notify() does not give the monitor to another thread (which would find free = true). This is my problem. Do you understand?
Many thanks for yuor answer anyway.

Optimal configuration for Cisco E3000 Router

Hi All,
Following are the details of my current home network setup, I would like to hear more recommendations and drawbacks of this setup.
ISP has provided with a Cisco DPC3825 DOCSIS 3.0 Gateway which has 4 Ethernet ports and a wireless networking but only 2.4 GHz.. This router is connected to the cable CPE box to internet. I have enabled the Firewall features of this router and disabled the Wireless network. This has also the DHCP server running.
The Second router is a Cisco E3000 which supports 2.4 GHz / GHz wireless networking. Connection to gateway is made via the 1st Ethernet port of gateway and then to the Internet port of E3000 router. I have connected my wireless devices to E3000 with GHz wifi lan. This router also has the firewall activated and DHCP server running as well.
Both routers have WEP2 Personal / AES security configured. Currently these two devices are on two different IP ranges ..etc gateway is 192.168.0.1 and e3000 is 192.168.1.1.
The E3000 is primarily configured for my online video for TV (Panasonic Vireacast). Please let me know if this is the best configuration or any other possible options.
Thanks,
RG

This configuration is called LAN to WAN configuration and this is the best configuration considering that you want to behave both the router as a router.
Because the other confiuration would be LAN to LAN then you can only use 1 router as a router and 2nd router as a switch.

The first configuration in the article is is LAN to LAN, scroll down the window for LAN to WAN configuration.

Nominal configuration for boot drive and internal RAID setup

Hello, I'd appreciate some advice on the following please.
I'm planning the build of a Mac Pro to act mainly as a photo editing workstation.
Considering the following disc setup:
Bay 1. 500GB with two partitions - 150GB for OS X and remaining for applications
Bay 2. 250GB XP/Vista for occasional use. All Windows apps/data quarantined on this disk.
Bays 3 and 4. 2x 500GB RAID0 (backed up externally) for data and workspace.
WRT RAM, I've read that 4 matched DIMMs in the same riser is the optimal config, so looking at 4x 1GB.
I'd be grateful for any comments as to whether I'm on the right track here.
Thanks
Ben
Mac Pro Mac OS X (10.4.10)

I set up a similar configuration for photo editing. First, partitions are not as useful as they were in the pre OS X era. Just load your OS and all applications on the same drive as there is no benefit, as far as I know, to separating them into partitions. Second, your 4 X 1GB RAM should be split between the two risers, not on the same riser. Put two DIMMs in the first two slots of each riser. 4 X 1GB hits a sweet spot in the cost/benefit analysis as long as you don't need more than 4GB. I use Lightroom extensively and 4GB is plenty.

OER Atrifacts Store Setup and Configuration for CVS.

Hello,
My question is related to proper configuration of a CVS based Artifact Store in Oracle Enterprise Repository.
I've attempted to configure a CVS Artifact Store from within OER's Asset Editor (as described on page 27 of the OER Configuration Guide & pages 92-93 of the OER Admin Guide.) I have also ensured that this new Artifact Store is selected in the dropdown for the Submission Upload Artifact Store system setting on the OER Admin page. However, my configuration settings for the Store appear to be incorrect and I haven't found a CVS example that has been thorough enough to infer the proper settings.
So I'm hoping someone can assist me who has been through configuring a CVS Artifact Store for OER. I'll try to provide detailed information below with the hope that it may be of assistance.
First, analogous CVS settings that are configured for my standard CVS plug-in in Oracle Workshop. These settings are for the pserver protocol, but I think they will provide some value to someone who has experience in configuring a CVS Artifact Store.
The standard Eclipse CVS plug-in settings for our enterprise repository location:
Connection Type: pserver
User: sampleuser
Password: Pa55wd
Host: dev003
Repository Path: /cvs/Integration
This translates to repository location --> :pserver:sampleuser:Pa55wd@dev003:/cvs/Integration
(Which is the root of our enterprise CVS repository)
Now…within this repository location above there is a module (Development/OER-POC) that is located in:
/cvs/Integration/Development/OER-POC
…and checked out into a project called "Sandbox" located in the default workspace in Oracle Workshop.
Additionally, within the organization we also have HTTP access to CVS. This previous example XSD I just mentioned has an HTTP URI of:
http://dev003:8080/viewcvs/viewcvs.cgi/Development/OER-POC/src/schemas/ExtOfAddrRef/v1/ExtOfAddrRef.xsd?cvsroot=Integration
Now as I have attempted to properly set up the configuration for the OER Artifact Store I have "translated" the above information into the following entries on the Artifact Store setup screen:
Name: CVS Enterprise Store
Type: Raw SCM
Hostname: dev003
SCM Location: Integration (??? Not sure if this has been inferred correctly. If not what should be specified here.)
SCM Type: CVS
Download Path URI Suffix: cvsroot=Integration (??? Not sure if this correct based in previous information?)
Download Path URI: (??? Not sure what should be specified here. I have inferred several logical options but they have not worked.)
Finally, when I referenced page 62 of the ORE Core Registrars Guide PDF the "Additional Development documentation" link (http://devwiki.flashline.com/index.php/B02831) states:
• "All files from an SCM will be URL addressable. The SCM (or a third party) must provide a way to get a particular file based on a URL. In other words, we are not going to use any client libraries to write code that will retrieve us a file from an SCM. "
• "Added concept of a 'download path' to an artifact store. For example, consider our development environment. Eclipse will have SCM information (i.e. cvs.flashline.com), eclipse/cvs project information (i.e. projects/framework/modules/com.flashline.geneva.rbac), and file/cvs file information (i.e. /code/com/flashline/geneva/rbac/base/RoleContextPersistBroker.java?rev=1.66). Using this info, a fileinfo's uri can be set. The artifact store will then allow us to specify a download base path such as http://cvs.flashline.com/viewcvs/viewcvs.cgi/."
To conclude my questions are:
1) Based on the comments in the Registrar's Guide it seems clear that the intent of an Artifact Store is purely for the support of downloading the physical artifact that corresponds to an OER asset. I would conclude that "Raw SCM" based Artifact Stores do not intend to support direct check-ins for the various SCM systems. (rather assets/artifacts in Eclipse would be manually checked in from within the IDE environment). If someone could confirm whether this is correct that would be much appreciated.
2) Based on the information I supplied for the example enterprise CVS repository...what would the appropriate settings be for these fields on the Artifact Store setup screen:
a) SCM Location
b) Download Path URI Suffix
c) Download Path URI
3) Since the "CVS" SCM Type does NOT specify fields for username and password (unlike when you select other potential SCM Types in the Store setup screen); how should one handle credentials in CVS repositories?
Thanks in advance to any assistance.

Hello user642477,
I'm facing the same problem.
It seems to me that the Oracles's guide line don't give enough information. I'll try to fixed it and whether I'm able to do so far I'll be in touch...
By the way, how could you browse to the link: http://devwiki.flashline.com/index.php/B02831? When I try it so a page cannot be displayed message is displayed.

Hard Drive configuration for speed

I've got a question regarding the best hard drive configuration for my mac pro. I'm looking to increase the boot speed, application load speed and particularly the speed with which hard drive intensive photoshop processes complete. Right now I'm just using some normal SATA II drives. I'd appreciate it if you could give me some feedback on the various options I am currently considering.
-2x 64GB SSD in a RAID 0 for OS X and applications with some large SATA drives for storage
-4x 300GB VelociRaptor 10k RPM SATA HDD in a RAID 0
-2x 147GB SAS 15k RPM HDD in RAID 0 with some large SATA drives for storage
I am particularly in the dark about the controllers I'd use for each solution. Clearly, I would absolutely require a PCIe card for the SAS drives, but would there be a marked advantage to using a hardware RAID card for the SATA drives over the software RAID in OS X? Also, how easy is it to get the mac pro to boot off drives connected to a controller card rather than the standard setup? And lastly, if there is good reason to use a card, are there any in particular that you would recommend?
Thanks a lot!

2. No. Do not make two partitions unless you do not plan to use Boot Camp Assistant to install Windows on that partition. If you plan to create a Boot Camp partition then you must partition the drive as one Mac OS X volume. Boot Camp Assistant will then create the Windows volume.
3. This drive must be repartitioned and reformatted as follows:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Set the number of partitions from the drop down menu to two. Use the graphic resizer to set the desired sizes for each volume as you want. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the first volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
7. Select the second volume you created and repeat Steps 4-6.
4. Now here I don't know what you think is your best option. You can buy any two hard drives you want. The ones I identified were only an example of what you could purchase for under $300. There are others, slightly more expensive, that would work, and you would still be under your $300 budget. The Samsung drives are good drives and reasonably priced, but they are just one of several alternatives. You should do some checking on your own before making your decision. I'm just giving some guidance, not trying to tell you what you should do. I've provided three sites where you can read reviews and benchmarks before you decide. You need to "own" your decision.
As for how you configure these two drives that's a secondary issue. I would recommend using them for backup. Two possible arrangements are a Mirrored or a Striped RAID array. A mirrored RAID array would create one volume that has a 1 TB capacity. Everything saved to that volume is essentially saved twice - once on one drive then a copy is mirrored to the other drive. This is not what you described in your Item 4. That's not how it works. Anything saved to the mirrored RAID array is saved the way I described it just above. It makes no difference where the files come from.
Now you can use the mirrored RAID array as a Time Machine backup drive if you want, but then you should not use it for other data storage. You would need the entire capacity as backup for both of the 500 GB drives you currently have. A mirrored RAID provides some data redundancy by having a copy of everything one each drive. Thus, if one drive fails the other drive still functions and your data backup is intact. Mirrored RAIDs are generally no faster than an individual drive that makes up the array.
The second suggestion was to make a Striped RAID array. This type of array produces one volume that is twice the size of the the two drives that make up the array. Thus, you would have a single volume that is 2 TBs in size. You can use this volume for your Time Machine backups also. Striped RAIDs do not provide any data redundancy. If one drive fails all the data stored on the RAID will be lost. However, Striped RAIDs are nearly twice as fast as either drive that makes up the array. This would give you very fast storage and backup.
You could also just leave the two drives to operate independently. Use on for Time Machine backups, use the other for more storage space.
Other possibilities abound. It's pretty much up to you to decide what will fit best into your needs today and in the future. Don't feel obliged to do what one person tells you. Five different users on the Discussions will give five different opinions.
I suggest you educate yourself a bit on backup and restore by reading the FAQ about backup and restore at The XLab FAQs.
Following is more information on RAIDs:
RAID Basics
For basic definitions and discussion of what a RAID is and the different types of RAIDs see RAIDs. Additional discussions plus advantages and disadvantages of RAIDs and different RAID arrays see:

Hardware or Software RAID?
RAID Hardware Vs RAID Software - What is your best option?
RAID is a method of combining multiple disk drives into a single entity in order to improve the overall performance and reliability of your system. The different options for combining the disks are referred to as RAID levels. There are several different levels of RAID available depending on the needs of your system. One of the options available to you is whether you should use a Hardware RAID solution or a Software RAID solution.
RAID Hardware is always a disk controller to which you can cable up the disk drives. RAID Software is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware.
Pros and cons
Software RAID is more flexible than Hardware RAID. Software RAID is also considerably less expensive. On the other hand, a Software RAID system requires more CPU cycles and power to run well than a comparable Hardware RAID System. Also, because Software RAID operates on a partition by partition basis where a number of individual disk partitions are grouped together as opposed to Hardware RAID systems which generally group together entire disk drives, Software RAID tends be slightly more complicated to run. This is because it has more available configurations and options. An added benefit to the slightly more expensive Hardware RAID solution is that many Hardware RAID systems incorporate features that are specialized for optimizing the performance of your system.
For more detailed information on the differences between Software RAID and Hardware RAID you may want to read: Hardware RAID vs. Software RAID: Which Implementation is Best for my Application?
OS X has software for creating RAIDs by using Disk Utility. Open Disk Utility and select DU Help from the Help menu. Search for "raid" without quotes. You will find information on how to set up mirrored and striped RAIDs using Disk Utility.

Best Xserve configuration for MySQL?

Basically, I'm trying to figure out the optimal configuration for our next Xserve. Obviously, more RAM, more CPUs, more and faster disks in RAID, etc will improve things. But considering that money doesn't grow on trees, what have some of you found to be particularly cost-efficient in building an Xserve to run mainly MySQL where there are many small INSERTs on indexed (!? tables of 10 million or more rows (DB size of ~1GB, presently). I realize it's kind of a "depends if" type of question, but I'm just curious what people have found. (I've also read that AnandTech article that wasn't too kind to Mach.)
Anyway, I was thinking of an quad-core Xserve with 4-8GB of RAM, and a RAID5 set of 15K SAS drives. Well, there's not much in terms of options anyway. But this box will be like I said 90% running services that depend on MySQL performance. Some Web services, but mainly automated MySQL stuff.
Should I even bother to look at a Sun or Dell running Linux?
I'm presently running primarily an Xserve dual G5 2GHZ with MegaRAID in RAID5. As I said, the key database is about 1GB with ~10 million rows (mostly in just two tables). So, small data sets, already heavily indexed... Anyway, any thoughts are very welcome. Here is a status snapshot of the past couple days:

RAID 5 is the worst possible storage option for databases.
That's not to say it won't work, but it has an overhead that will impact disk I/O, especially writes and it sounds like your data set is write-heavy.
This is because a write requires a Read-Modify-Write process for every write - whenever you write data to the array it has to read all the existing data in the corresponding blocks, recalculate the new parity data, then write it all back.
This may or may not be a problem for you, depending on actual quantity and scale of the writes, but if you're looking for the best configuration, RAID 5 is not it.
For optimal performance use RAID 0. Of course, RAID 0 has no protection, so you need to deal with that.
The ideal combination is RAID 0+1, but that requires a minimum of four drives, while the XServe can only handle three internal drives.
As for the rest of it, you really need to analyze your data more before you can get an answer.
The number of rows is largely irrelevant if you're just inserting data. It has some bearing on indexes, so you need to look at how your data is indexed.
As for memory, the ideal configuration is at least enough memory for MySQL to load all the indexes into RAM - most lookups should be indexed and if those indexes fit entirely within the memory space you're off to a good start.
Note that the standard MySQL is 32-bit, so you're limited to 2GB for InnoDB or MyISAM (whichever you're using). You'll need the 64-bit version to use more memory than that.
Most performance bottlenecks (and gains) can be traced to either indexes (too many indexes can be just as bad as not enough), and application (there's significant overhead in opening a new MySQL connection (which is a large factor in the AnandTech article), so try to ensure that your application uses connection pools (where a number of connections are opened when the app starts, and reused through application processes rather that a new connection opened for every query). Without knowing the application it's impossible to narrow that one down much more.
As for Sun or Dell - sure, they're options. Just be aware that you'll need Solaris or Linux admin skills in order to get the most out of them. They may (but not necessarily will) perform faster at the end of the day, but it may also take you much time and heartache to get there.
The other thing that you don't mention is why you're looking to upgrade. Is the G5 currently stressed? If so, where? what's the typical CPU load? disk activity level? network load, etc.
It doesn't make any sense upgrading the machine if the network is your bottleneck - all you're going to do is move that same bottleneck to a different machine.

Change project directory for Workshop?

The default project directory for workshop is
C:\bea\weblogic700\samples\workshop\applications. How do I change that.
For example I want my project to be in the directory c:\work\webservices
thx

Yes Raj. That helped, it worked!

Dave,
You can change the server with which Workshop communicates by modifyingthe
Config directory entry available under the Tools->Preferences->Pathsoption
on the IDE.
In your case the config directory should be c:\
and the domain should be foo.
also make sure you change the port number entry to the one the server infoo
is listening on.
Hope this helps.

OK. I added a new domain (e.g., foo) and pointed the directory to one
of
my
choosing (c:\foo). Weblogic then created a c:\foo\applications
directory.
Ok, how do I get workshop to use that directory for my development
project(s)? When I start if from my start menu it uses the cgserver
instance and when I create a project it creates it in the samples
application directory.
"Raj Alagumalai" <[email protected]> wrote in message

Dave,
When you create a project in Workshop, the project will be created
under
the
applications folder of the server with which Workshop is
communicating.
For
every project that you create via Workshop there is a corresponding
fully
exploded web application that is created on the WebLogic Server. This
restricts the ability to have the project reside in a different
location
other than the applications folder.
If you do not want the project to be created in the samples directoryyou
can configure a new domain via the domain configuration wizard. But
the
project would still be under the applications folder of the newdomain.

Hope this answers your question.
Thanks

Physical DB Configuration for 11g

Hi,
Can someone please let me know what can be the good configuration for designing a Database of size 1TB in 11gR2.
1) How much size we can allocate for Undo tablespace keeping the undo retention value to default
2) How many redo groups and how many members per group considering the log switch are not very frequent ( 2-3 groups should be enough and 2 members per group and each member can be 200MB. Let me know if we can design it in a better way)
3) Size of system,sysaux and temp tablespaces
Thanks in advance.

Its not so easy to answer your question if you are gonna create a 1TB database fresh.
But as you had estimated the size of the database;I presume you have a similar set up (production/staging/dev/test).
So perform the follwing in order to decipher your concerns:
1) How much size we can allocate for Undo tablespace keeping the undo retention value to default
Sizing an UNDO tablespace requires three types of information; viz:
--Number of undo data blocks generated per second (UPS)
--UNDO_RETENTION in seconds (UR)
-- Overhead varies based on extent and file size (db_block_size) (DBS)
UndoSpace = [UR * (UPS * DBS)] + (DBS * 24)
In this UR and db_block_size can be obtained from pfile or spfile.
The third piece of the formula (UPS) requires a query against the database. The number of undo blocks
generated per second can be acquired from V$UNDOSTAT.
The following formula calculates the total number of blocks generated and divides
it by the amount of time monitored, in seconds:
SQL>SELECT (SUM(undoblks))/ SUM ((end_time - begin_time) * 86400)
FROM v$undostat;
Column END_TIME and BEGIN_TIME are DATE data types. When DATE data types are subtracted,
the result is in days. To convert days to seconds, you multiply by 86400, the number of seconds in a day.
The result of the query returns the number of undo blocks per second. This value needs
to be multiplied by the size of an undo block, which is the same size as the database block
defined in DB_BLOCK_SIZE.
The following query calculates the number of bytes needed:
SQL> SELECT (UR * (UPS * DBS)) + (DBS * 24) AS "Bytes"
FROM (SELECT value AS UR FROM v$parameter WHERE name = 'undo_retention'),
(SELECT (SUM(undoblks)/SUM(((end_time - begin_time)*86400))) AS UPS FROM v$undostat),
(select block_size as DBS from dba_tablespaces where tablespace_name=
(select upper(value) from v$parameter where name = 'undo_tablespace'));
NB: The above described UNDO calculation is compiled from Metalink Note : 262066.1
2) How many redo groups and how many members per group considering the log switch are not very frequent
(from Metalink Note : 781999.1)
An excerpt from the Oracle Database Performance Tuning Guide provides the general guideline.
"It may not always be possible to provide a specific size recommendation for redo log files, but redo log files in the range of a hundred megabytes to a few gigabytes are considered reasonable. Size your online redo log files according to the amount of redo your system generates. A rough guide is to switch logs at most once every twenty minutes."
So if your online redo logs (for example) switch once every 5 minutes during peak database activity, to achieve the 20 minute guideline, the logs would each need to be 4 times larger then their current size. (i.e. 20 / 5 = 4)
3) Size of system,sysaux and temp tablespaces
i) SYSTEM tablespace's size - dont have much idea; what should be the minimum size of the SYSTEM tablespace. But in most of the cases a size of 500 to 600 MB should be fine
ii)SYSAUX tablespace's size - Default size for SYSAUX is 210Mb. Once again; most of the case a size of 400 to 500 MB should be fine
iii)TEMP tablespace's size - You have to monitor the TEMP space usage continuosly in order to zero on an optimal size.
You can query DBA_TEMP_FREE_SPACE for this in order to get how much TEMP space is allocated and how much is free.
SELECT * from DBA_TEMP_FREE_SPACE;
TABLESPACE_NAME TABLESPACE_SIZE ALLOCATED_SPACE FREE_SPACE
TEMP 250609664 250609664 249561088
Hope this helps

SAP DMS - How to do an external DMS configuration for the existing system ?

Hi All.
Greetings.
Request help and understanding.
Am new to the world of SAP. And request SOME clarity for understanding of DMS.
We are wanting to put an external DMS server and wish to configure for the same.
So that the load on the production SAP R/3 database is reduced.
We are now wanting to test the same on Dev environment.
From SDN Link :
I understand that :
DMS basically has a content server. which stores documents.
That can be accessed through Web, SAP R/3 Gui , SAP Portal.
I have gone thro various links and the following links i have found to be informative and helpful :
http://help.sap.com/saphelp_erp60_sp/helpdata/en/c1/1c31a243c711d1893e0000e8323c4f/frameset.htm
http://wiki.sdn.sap.com/wiki/display/PLM/DMS+Customizing
http://help.sap.com/saphelp_nw70/helpdata/en/59/fba637fcf7dc39e10000009b38f8cf/frameset.htm
However, would like to know the following because am not getting the clarity :
1) Is there any supported platform / compatibility guide for DMS ?
if yes, can someone send me the link?
2) We have oracle 11g as our for SAP R/3 backend.
Windows 2003 server 64 bit system.
When i check the system status on the dev server of sap.
It says. ECC 6.0 Rel 7.00 update 20 (hOpe am reading it correctly)
After much search on the SMP site,
we finally discovered and downloaded the DMS software for unicode and / 64 bit.
Which we saw under the maintenance components separately seen for DMS 7.0
Now for this DMS content server which we would like to make it external for storage of documents -
do we need to have a separate database for this purpose as a repository.
If i run a setup of DMS - will that automatically install any default repository for this or
will it allow me to choose any other repository for the same ?
Can anyone advise on this.
Because this link says content server is based on Instance of MAXDB : http://help.sap.com/saphelp_nw70/helpdata/en/59/fba637fcf7dc39e10000009b38f8cf/frameset.htm
3) I read some thing like this on some of the SDN links :
P40 - Integration of DMS
P62 - R&D Document Manage¬ment and Workflow
P71 - Document management
What are they referring to.
4) We would be accessing these thro web, gui, customised portal.
This content server configuration is a bit confusing.
5) Is SNC configuration required to be done for the separate DMS server setup.
If yes, how to do that ? any configuration link for that please ?
Can anyone advise on the things to do.
Steps to do.
What all are the pre-requisites to check, before we start the set up of DMS.
Can anyone help me understand this whole thing regarding the DMS installation and configuration.
Step-wise.. from the start to end.
Because it gives me a lot of uneasiness without having everything in place before we could say we could start the whole process of configuration / installation.
Many thanks for your help in advance.
Wishing you a happy and relaxed weekend.
Kind regards
Indu

Thanks christoph & pradeep kumar.
did a few more research and atleast have come to understand that.
DMS server installation has content server which works only with MAXDB.
So my understanding is correct.
And what we see as Easy DMS is a client installation.
which probably i would look at at a later stage.
Found this link to be a little more informative :
http://www.sapfans.com/forums/viewtopic.php?f=12&t=330558
I really wish. That life were to be so easy. To call a consultant and finish it off
Wishful thinking
thanks and cheers

How to have Multiple Configurations for a Flex Application

Hi All,
I've seen this question asked in various forms multiple times, but never answered: How do you set up a FLEX configuration to have different configurations for development (local), test server, staging server, beta server, and production server? I cannot imagine that Adobe has not accounted for this, something that is very standard in most development teams. Zend Framework has a very elegant solution for this: in the configuration file you define all aspects that can be configured, as well as the various environments (development, staging, beta, live, etc.). Then, in the bootstrap file you specify which environment you want to work in, and you're all set.
How can something like this be achieved in FLEX?
Many thanks!
-Mike

Maybe my setup is unconventional, I doubt it, though:
1) SVN repo stores FLEX and PHP codebases in separate projects.
2) Developer gets code from repo, and runs on local machine. -> need to configure FLEX to point to local PHP code here for Remote Objects.
3) Developer then publishes Flex app to staging server. -> need to configure FLEX to point to staging PHP code here.
4) Flex app then gets published to live server. -> need to configure FLEX to point to live PHP code here.
Now, using ANT, the scenario would look like this:
1) SVN repo stores FLEX and PHP codebases in separate projects.
2) Developer gets code from repo, and runs on local machine. -> need to configure FLEX to point to local PHP code here for Remote Objects.
3) Code is good and developer checks it back into SVN.
4) ANT extracts latest build from SVN and builds it, then publishes to staging server. -> need to configure FLEX to point to staging PHP code.
I am using PHPUnderControl as my build server for PHP.
I am also unclear as to how my goal could be achieved using ANT?
Thanks!
Mike

ASA 5505 configured for WebVPN connecting to Citrix Web Interface

ASA 5505 configured for WebVPN connecting to Citrix Web Interface.
i have a ASA 5505 that I am attempting to configure for WebVPN with passthrough into Web Interface . The user authenticates into WebVPN OK and gets the option to click on the Citrix Link (which is i add bookmark citrix server http:// 172.30.40.5.) i enter the citrix and then for example i want to open to outlook it can not open. (when i want to open some application no application is open)).there is no alarm at asa. how i solve this issue?
thanks.

Teymur,
Can you confim that after disabling the ssl/tls on the Citrix server (secure connectivity) that you are getting exactly the same error. It is possible that it is generating a different error.
The bug where we have see the existing error was CSCtf06303 but that has been fixed in 8.4.1. Can you confirm the exact version of code you are running on the ASA.
If you have confirmed the above two notes it may be adventageous to open a TAC case as we may need to do some live additional troubleshooting.
Thanks
-Jay
