Performing SPAU after upgrade - Obsolete Note Correction

Hi all,
do we have to reset all those obselete note correction in SPAU after technical upgrade? What are the impact if we do nothing to those obselete note correction?
thanks

Hi Valerio,
As we know, all modification of SAP standard will be overwrittten by Upgrade new standard objects. Those objects that have been overwritten will be listed in transaction SPAU and SPDD. So, we have to decide either to RESET or ADOPT MODIFICATION or do nothing.
The following are the impacts for each action:
1. RESET - Object will be reset to original SAP. Once reset, some field value in SMODIFLOG table will be changed. Field 'INACTIVE' value in the table will be set to 'R' meaning RESET. Impact - this object wont be listed again in SPAU or SPDD list in next SP upgrade or version upgrade.
2. ADOPT MODIFICATION - Modification in previous version will be adopted into new objects. Field 'INACTIVE' value will be set to blank meaning that the object is a modification or note correction.
3. Do nothing - the objects or note correction will appear again in next SP or version upgrade.
Hope that answer your question.

Performance issue after Upgrade from 4.7 to ECC 6.0 with a select query

Hi All,
There is a Performance issue after Upgrade from 4.7 to ECC 6.0 with a select query in a report painter.
This query is working fine when executed in 4.7 system where as it is running for more time in ECC6.0.
Select query is on the table COSP.
SELECT (FIELD_LIST)
        INTO CORRESPONDING FIELDS OF TABLE I_COSP PACKAGE SIZE 1000
        FROM COSP CLIENT SPECIFIED
        WHERE GJAHR IN SELR_GJAHR
          AND KSTAR IN SELR_KSTAR
          AND LEDNR EQ '00'
          AND OBJNR IN SELR_OBJNR
          AND PERBL IN SELR_PERBL
          AND VERSN IN SELR_VERSN
          AND WRTTP IN SELR_WRTTP
          AND MANDT IN MANDTTAB
        GROUP BY (GROUP_LIST).
   LOOP AT I_COSP      .
     COSP                           = I_COSP      .
     PERFORM PCOSP       USING I_COSP-_COUNTER.
     CLEAR: $RWTAB, COSP                          .
     CLEAR CCR1S                         .
   ENDLOOP.
ENDSELECT.
I have checked with the table indexes, they were same as in 4.7 system.
What can be the reson for the difference in execution time. How can this be reduced without adjusting the select query.
Thanks in advance for the responses.

Dedeepya.

Hi,
ohhhhh....... lots of problems in select query......this is not the way you should write it.
Some generic comments:
1. never use SELECT
                   endselect.
   SELECT
into table
   for all entries in table
where.
   use perform statment after this selection.
2. Do not use into corresponding fields. use exact structure type.
3. use proper sequence of fields in the where condition so that it helps table go according to indexes.
    e.g in your case
          sequence should be
LEDNR
OBJNR
GJAHR
WRTTP
VERSN
KSTAR
HRKFT
VRGNG
VBUND
PARGB
BEKNZ
TWAER
PERBL
sequence should be same as defined in table.
Always keep select query as simple as possible and perform all other calculations etc. afterwords.
I hope it helps.

Pranaya

Performance degradation after upgrading to yosemite

I'm experiencing performance degradation on MacBook Pro 15 including
number of spinning wheels,
instance of dark screen,
overheating after upgrading to Yosemite
diminished battery life
Is Yosemite the cause of this and other issues

I can't believe Apple have made this software available to the masses when it's clearly not ready. Since "upgrading" my Mac mini has been pretty useless. Programs take a substantially increased time to open compared to Mavericks, and then performance is poor at best. Opening files in Photoshop, for example, is painfully slow and I get the colour wheel almost all of the time - something which definitely didn't happen with Mavericks.
Aside from this, I've experienced a number of frustrating bugs today. When I open a new program on my left screen the right screen is changed to a fresh desktop. Why? When I turn my Mac on I get the login screen on the left monitor (as it always used to) but then the primary desktop is set to the right and I've been unable to keep the correct setting so far (it forgets that I've changed it following a reboot). The background of the top bar keeps disappearing so all of the icons, time, etc. just sit on top of the desktop background.
I hope Apple can release a fix, and quickly.

Any performance gains after upgrade to Oracle 10 ?

Hello,
we have been using EBS 11.5.9 (with Oracle 9). Does anybody see any improvements from performance point of view after upgrade to Oracle 10r2 (but without upgrade of EBS to R12) ?
Regards

Somethings have been faster for us and somethings have been slower. In general it seems the same or better. When we get a chance to look at the jobs that are performing poorly I'm sure we will be able to make them perform. Make sure you find and apply all of the performance patches for the modules you have implemented, we are missing one right now and it is hurting our Configurator developers instance. I have actually set the the optimizer_features_enable back to 9i. This is something I would not recommend doing in a production environment, and we are only doing it until we can get the patch that fixes the optimizer in 10g applied.
One surprise for us was the increase in memory required, in our test and development instances we have found a 1GB SGA is as small as you can go with 10g and still have reasonable performance. We had a number of 9i ebus databases around 300-400MB SGA that performed just fine. This limited the number of environments we could squeeze on a single server (not really a bid deal if you only have a few dev, test and training environments).
In our production environment in order to have the same size datacache more memory was consumed. Were we could get away with a shared pool of 4GB under 9i, it grows to over 6GB in 10g. Looks like more PGA is also being used. 10g along with RUP5 and upgrading the java from 1.3 to 1.5 has increased our memory consumption. We increased memory from 64GB to 96GB and we are using a large portion of the additional 32GB. We were right at the limit with 64GB in our 9i production instance but we had never experienced the paging that we did with 10g. Now at 96GB we nolonger see any paging.

SharePoint 2007 performance issue after upgrading the operating system

We upgraded the operating system of our SharePoint Server 2007 from 2003 to 2008 R2. After upgrade we rebuilt the SharePoint using content DBs we backed up before upgrade. All settings is same except that we moved the DBs to new SQL servers. Now users are
reporting performance issue with sites. I experienced it myself some of the pages takes 9-30 seconds to load. Also our SharePoint server is single server. I monitored the SharePoint Server and it is fine. I did fiddler trace and here are the result. I see
lots of 401 (login failed) errors then 302 (redirect) then 200 (OK). Do you know why we are getting 401 errors?

Hi
when you request a Site collection (http://domain/) or a Site (http://domain/foo/) of your Publishing Site you get redirected to the http://domain/Pages/<WelcomePage>.aspx. SharePoint 2007 uses the 302 header (location temporarily moved) for
this purpose. Surprisingly even WSS uses the 302 header to redirect a root url to the default.aspx. In comparison ASP.NET uses an internal redirect to render the default page when the root url requested: there is no redirect in this situation.
Check the link which can give more input
http://blog.mastykarz.nl/sharepoint-2007-redirect-solved-using-301-instead-of-302-redirects/
for error 401 you can check this link
http://discussions.citrix.com/topic/97027-no-resources-401-unauthorized/d
and check SharePoint ULS logs and event viewer for any exceptions.
Please mark the Answer and Vote me if you think that it will help you to resolved your issue

Performance issue after upgradation

Dear All,
I am facing one problem, we have upgraded the existing 4.6c version to ecc 6.0 version for one of the client. And from the basis side everything is completed. But while I tried to run the z-programs in the new version i.e ecc 6.0 version it is taking long time than usual in 4.6c version. On observing the coding , the coding contains innerjoins of 4 to 5 cluster tables. Is this could be one of the reason for longtime execution or else any other reason is there. Do we need to performance tune the programs or else is there any procedure to reduce the program execution time without optimising the code.
Please help me and thankful to you all in advance
Regards
Rayasam

Did you delete the SQL packages on your system after doing the upgrade?
The existing SQL packages may no longer be appropriate, and may not be allowing the correct optimizations to occur.
Normally, the SQL packages will be deleted as a matter of course during the upgrade, but if it didn't happen for some reason, it can affect performance.
See the following, which discusses this issue:
<a href="http://help.sap.com/saphelp_erp2005vp/helpdata/en/ff/ff6dcb409f11d1896b0000e8322d00/content.htm">SQL Package Handling</a>
Also, even if the SQL package were deleted and rebuilt, it may take some time for the system to optimize with the new packages.
Good luck
Brian

3D performance problems after upgrading memory

I recently purchased an additional 2GB of memory to try and extend the life of my aging computer. I installed the memory yesterday and Windows seems to recognize it (reporting now 3.3GB) but when I dropped into WoW (pretty much the only game I have) the 3D performance was down from the usual 60FPS @ 1600x1080 to a bleak 20 (at best) and the CPU utilization went to about 80% on both cores (with ~20% kernel usages). Basically WoW was being software 3D rendered!!!
I went through the usual reinstall drivers, reboot, etc... and couldn't find a fix. I powered down, pulled out 2 of the memory sticks, booted up, and dropped into WoW - it ran at the full 60FPS and CPU utilization was very low (i.e. back to GPU Hardware 3D rendering). I powered down again, swapped the 2 sticks for the other 2 sticks, booted up, and dropped into WoW - again it ran 100% fine. So I powered down, put all four sticks in, booted back up, and when I dropped into WoW it was running in the software 3D rendering mode (20FPS at best and High CPU/Kernel usage).
I've tried the /PAE option in boot.ini - no joy. I've tried /MAXMEM = to 3300, 3072, 3000, and even 2048 - no joy in any of those cases. Has anyone seen anything like this before? Or have suggestions to fix (other than going to Win7-64)?
All info in signature is up to date.
Thanks in advance for any help!

PAE or Physical Memory Extension will not do anything as Microsoft has castrated this feature to such an extend that it has nothing to do with memory addressing anymore when in comes to Windows XP:
http://en.wikipedia.org/wiki/Physical_Address_Extension#Microsoft_Windows
Quote
Windows XP Service Pack 2 and later, by default, on processors with the no-execute (NX) or execute-disable (XD) feature, runs in PAE mode in order to allow NX. The NX (or XD) bit resides in bit 63 of the page table entry and, without PAE, page table entries only have 32 bits; therefore PAE mode is required if the NX feature is to be exploited. However, desktop versions of Windows (Windows XP, Windows Vista) limit physical address space to 4 GiB for driver compatibility reasons.
The feature is already automatically enabled. But since is original function (Address Extension) does no longer exist when it comes to the desktop versions of Windows XP, it won't really do anything you would ever notice.
About the /MAXMEM Switch: In Windows 32bit operating systems, every process is limited to 2GB of memory. The point of the switch is to allow certain applications (or their run-time process) to occupy a higher amount of system memory than 2GB. However, the culprit here is that only those applications are able to utilize this ability that have been programmed (or compiled) accordingly. A special flag (large memory aware) has to be implemented. Otherwise, these application will be restricted to 2GB even though the /MAXMEM Switch has been set to extend the 2GB limit to 3GB. Most 32bit applications come without the "large memory aware" flag and that is why usually, settings the switch won't change anything.
In any case, it is unlikely that /PAE (even if it would not be castrated) and /MAXMEM would have an impact on your actual issue because I doubt that it has much to do with either memory adressing or the memory limit of an indiviual Windows process.

the 3D performance was down from the usual 60FPS @ 1600x1080 to a bleak 20 (at best) and the CPU utilization went to about 80% on both cores (with ~20% kernel usages).
There are a couple of hardware based explanations to consider here. Let's start with the most obvious one:
1. 975X Memory Controller
The main reason that the system chooses to automatically set the Memory Speed to DDR2-667 even though DDR2-800 modules are installed, is that by design the memory controller of the Intel 975X Chipset does not natively support DDR2-800 modules, but
>>Intel® 975X Express Chipset Datasheet - For the Intel® 82975X Memory Controller Hub (MCH)<< [Page 20]
This means, that from the point of view of the memory controller, operating the memory @DDR2-800 actually means overclocking it (with all potential side effects).
Basically, if your initial problem disappears as soon as you reduce the memory speed to DDR2-667, the design limitation of the memory controller may explain your findings.
2. Different memory modules
If I read your signature correctly, you are actually mixing two different kits/models of RAM (CM2X1024-6400C4DHX and CM2X1024-6400C4). This can work of course, but in practice it not necessarely does under all circumstances.
This list (-> http://ramlist.i4memory.com/ddr2/) indicates that there are at least 14 different module types/revisions of Corsair DDR2-800 / CL4 modules that utilize a wide range of different memory chips (Elpida, ProMos, Micron, Infinion, Powerchip, Qimonda, Samsung, Infinion etc.). Even though the superficial specifications for these chips appear to be pretty similar (DDR2-800 / CL5 / CL4), this does not necessarely mean that the modules will respond to the same operating conditions in the same way. There may be small difference in sub-timings/sub-latencies and/or the general responsiveness of the ICs which may affect the operating behaviour of the memory controller (which by the way also includes the PCI-Express interface which your video card is hooked up to).
And again: If running the system @DDR2-667 solves your issue, the possible explanation is that higher clock speeds may amplify (or trigger) potential performance problems that could have to do with the use of non-identical memory modules.
Furthermore: It is also possible that the memory controller's design limitations and the potential compatibility problems that may be attributed to mixing different modules types may reinforce each other in terms of reduced system performance.
3. The BIOS may have an impact as well
There has been known issue with the use of certain video cards in conjunction with 4GB of system memory on this mainboard:
https://forum-en.msi.com/index.php?topic=107301.0
https://forum-en.msi.com/index.php?topic=105955.0
https://forum-en.msi.com/index.php?topic=99818.msg798951#msg798951
What may have come out as graphics/display corruption in earlier BIOS Releases may come out as reduced system performance when using the latest BIOS Release. Of course, this is hard to prove, but I thought I'd mention it anyway. May I ask what amount of video memory your card has onboard?
Fortunately, there is a BIOS version that you could consider to try in this matter. It is not only the last BIOS Release that could be used in order to avoid the corruption issue, but it is (in my oppionion) the best BIOS Version that was ever released for the 975X Platinum PUE Mainboard: W7246IMS.716 [v7.1b6]. I have been using this mainboard for almost two years and have tested almost every BIOS Release that ever came out and I always went back to v7.1b6 as "ground zero".
It will properly support your E6600 (so you don't have to worry about that) and as far as I remember, there are no known compatibility issues with other components. So maybe, you want to give this a shot.
The bottom line is that in a worst case scenario, the problem you describe could be caused by all of the above things at the same time. You cannot really do anything about the 975X Chipset Specifications and the only way to rule out explanation #2 is to test modules that are actually identical (same model number, revision and memory chips). A test of the 7.1b6 BIOS Release is something you should consider. It may be the only way to test the BIOS Hypothesis.
This post turned out to be longer than I intended, but then again, I am well-rested after a good sleep and the wake-up coffee is kicking in pretty good.

Db performance degradation after upgrading a VM from EL 4.7 to EL 4.8

Hi,
We performed an OEL4.7 to OEL4.8 migration for a vm; we did not upgrade the dom0.
Here is the config data:
vm:
OLDl:
OEL4.7
2.6.9-78.0.13.0.1.ELsmp 64bit
HVM
NEW:
OEL4.8
2.6.9-89.0.23.0.1.ELsmp, 64bit
HVM
dom0(unchanged):
OVM 2.1.2, 2.6.18-8.1.15.1.31.el5xen
DB version:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit
No init param changes!!!
After the migration, the only kernel params that have changed, are below:
Kernel settings.     4.8      4.7
kernel.shmmax     4398045611104     12884901888
kernel.shmall     1073741824     3145728
sunrpc.tcp_slot_table_entries     16 32
net.ipv4.ip_local_port_range     9000 65500     1024 65000
fs.file-max     6815744     270336
Problem:
The application response time increased by 100%, and the most heavy queries, after running the load
test and the ASH report, deal with "CPU+wait for CPU" event.
Unfortunately, I don't have the explain plan of these queries before the OS migration so I can identify
the impact on the exec plan.
So far, I have not been able to determine the cause of this problem and I really appreciate some help at this
point.
Thank you.

What's a MT client? How to read your kernel parameters, 1st 4.7, 2nd 4.8?
Looking at your kernel parameters... is there some typo? I think the values don't make much sense, e.g. shared memory segment 4 TB -> 12 GB? Either way this looks very strange to me. Same for fs.file-max, etc. I'm not sure if setting shared memory segment to more than 4 GB is actually supported. Where did you get these parameters?
http://www.oracle.com/technology/pub/articles/smiley_10gdb_install.html#kernel
I would also verifiy your shell ulimits.
Edited by: Markus Waldorf on Jul 23, 2010 5:58 PM
Just noticed your kernel parameter are 4.8 <- 4.7. Anyway, I wonder what value will actually be used if you set shared memory to 4 TB, but you can probably verify with
/sbin/sysctl -a | grep kernel.shmmax
Edited by: Markus Waldorf on Jul 23, 2010 6:15 PM
The following values are probably more common. Shared max is 2 GB.
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 262144
net.core.rmem_max = 262144
net.core.wmem_default = 262144
net.core.wmem_max = 262144
Next, edit your “/etc/security/limits.conf” file, adding the following lines:
oracle          soft    nproc           2047
oracle          hard    nproc           16384
oracle          soft    nofile          1024
oracle          hard    nofile          65536
If your current “/etc/pam.d/login” file does not already contain the following line, add it:
session    required     pam_limits.so
Finally, add the following lines to your "/etc/profile" file:
#Tweaks for Oracle
if [ $USER = "oracle" ]; then
    if [ $SHELL = "/bin/ksh" ]; then
    ulimit -p 16384
    ulimit -n 65536
    else
    ulimit -u 16384 -n 65536
    fi

Performance Problem After upgrade to oracle 10g

Hi
I have upgrade one of my datawarehouse database from oracle 9.2.0.8 to oracle 10.2.0.4 running on solaris 9
After the upgrade jobs which were running in the database is taking hell lot of time.
The jobs are accessing the views which is used to get the monthly report data from the database.
what could be the solution and where to start from to get the RCA to resolve this performance issue
Please let me know if you require any other information
database is currently running in the automatic shared memory management mode ie SGA_MAX and SGA_TARGET parameters are defined for that

There are a lot of differences between 10g and 9i in this regard, among these are:
- There is a default job that gathers statistics every night which is not there in 9i. You might have totally different statistics as in 9i due to that job, depending on how and if at all you used to collect statistics in 9i
- The 10g DBMS_STATS package collects histograms on some columns by default (parameter METHOD_OPT=>'FOR ALL COLUMNS SIZE AUTO' default in 10g whereas 'FOR ALL COLUMNS SIZE 1' in 9i) which can have a significant effect on the execution plans
- The 10g optimizer has CPU costing enabled by default which can make significant changes to your execution plans due to different costing of table scans and order of predicate evaluation. In addition it uses NOWORKLOAD system statistics if system statistics have not been gathered explicitly
- 10g checks the min and max values stored for columns in the data dictionary. If your predicates are way off compared to these values then 10g begins to adjust the calculated selectivity of the predicate which can again significantly affect your execution plans
- 10g introduces the "Cost Based Query Transformation (CBQT)" feature which means that rather than applying heuristic transformation rules transformations are costed and potentially discarded whereas 9i applies transformations unconditionally whenever possible

Performance issue after upgrading database 9i (9.2.0.5.0) to 10g (10.2.5.0)

Hi,
recently we have upraded our database from 9.2.0.5.0 to 10.2.5.0. After the upgrading of the database some of our SQL-statements, who gather data and fill it in an empty tabless,
shows a really bad performance in the new database version. We already have checked the explain plan it remains the same in both versions (full table scans on the corresponding tables)
E.g. a query running in the 9i database needs 17 minutes for completion in the 10g version it needs 15 hours.
We have checked the running session and have seen that the read of database blocks of the corresponding tables needs immense more time in the 10g version.
Are there any oracle parameter, hidden features we can adjust in 10g in order to get the same performance as in 9i?
thanks in advance

There is no 10.2.5.0 version - I assume you mean 10.2.0.5.

Wifi erratic on 4S after upgrading and not working even after resetting to factory setting. Why should apple isolate itself from their own product problems Matter of shame when they are not ready to communicate with the customer means they are dead.

Dear Sir/Madam Since the wifi is not coming ON how can I open this diagnostic on the iphone 4S am using and having problem with wifi behaving in erratic manner.
Am a professional engineer for projects and am 68 yrs old. At one time was looking after a production line manufacturing I C's in semiconductors manufacturing company of the US.
Have four apple products, one hp laptop and one DELL professional computer at home is used by only two members me and my wife.
Wife prefers working on ipad2 or ipad mini while traveling and has iphone 4. Am using iphone4S with laptop and Dell computer, No apple product is more than two years old.
Am having the problem in using wifi on the 4S after it was upgraded to the latest ios as per the recommendation by your software of my iphone 4S
The wifi card hangs up at it's own will and even a visit to your authorized service center in Delhi has not able to help me although they have reverted the ios back to the
one supplied with the set. Am a user and not a computer expert but it looks like the wifi card is not able to some times take the load while working which could indicate the wifi card is getting heated up.
My daughter who is Masters in 3D Animation is an ardent fan of apple products working at present in Canada was also gifted by me a 4S about 4 months back. My daughter-in-law is using iphone4 and an ipad for her professional works along with a Dell PC in the US. While my son is a fan of samsung products and does not like an apple product.
So in a family we have 7 apple products except MAC laptop/PC.
But the fact is, this problem with 4S has really shaken me up and now it seems your products are deteriorating in quality while demanding the best pricing structures.
Since this is purely the device and the software of apple problem you may please replace this set with new one as neither have any time to push you/ request you after your service centre
in Delhi told me yesterday this cannot be repaired.
The serial No of my set is DN*****TC0 and was bought from an authorized dealer and so were the other products from the same dealer in Delhi. This set is still in showroom condition and
was never used without a protective cover.

Major performance Issues after upgrading to 10.9.2

Hi,
I have been having major performance issues almost preventing me from using the computer at times. I suspect I don't have enough memory to run Maverick as the computer was great before I upgraded.
If any experts or people with ideas for me to speed up the computer, please respond. If you think the only way to improve performance is add memory or revert back to a previous version of OSX that I have a backup for, let me know.
Here is the info on my system, thank you in advance!!

The performance issues are due to third party software. Mavericks at the minimum requires 2GB's of RAM but I don't think that's the issue. And you can upgrade RAM anytime.
MacKeeper should be uninstalled. It does far more harm than good.

Aperture 3 library performance tip after upgrading

This tip may be helpful for anyone experiencing slow project/album loading and beachballing even with no background processes running in aperture 3.
I was having some major issues with performance in aperture 3 with all library/project/album and book loading operations. It was very odd because Adjustment performance is very good.
All my imported aperture 2 books would beach ball for about 50 seconds to load, and then each page would take 10 seconds to load after clicking on it. In comparison my aperture 2 library was near instantaneous.
After exporting the project as a separate library, rebuilding the library, repairing permissions, nothing was working.
As a last ditch effort before opening up Shark - I decided to open up the library in the finder, and manually delete all of the original previews. I then opened up the library in aperture and manually updated all the previews by highlighting all the thumbnails and right clicking -> update previews.
Once this process completed I quit aperture and restarted to see if I was still getting any slowdowns and the problem is now gone! Library loading and project switching operations are speedy as ever now, and the book navigation is faster than aperture 2 now.
Hope this helps anyone with performance issues.

Speak up if anyone has problems migrating because of previews or is successful in migrating without previews. I suspect this is my problem. I get to:
Upgrading Library 7% complete (updating master metadata - 5,068 remaining)
After restoring from a file vault with Aperture 2, I get to the same spot, with or without previews. Although this is a slightly different issue, I tried deleting previews within Aperture and reimporting. I got to the same exact spot as before. The computer becomes nearly unresponsive, and I have to force quit Aperture after hours of sitting at 5,068 remaining.

Performance problem after upgrade from Web version to Basic version

A couple days I ago I 'upgraded' my SQL Azure database from the Web service tier to Basic. Since doing that the performance on many of my queries as dropped noticeably. I've made no schema changes, and the amount of data in my database has changed very
little since the upgrade. Has anyone had this same problem?
Randy Minder

Randy,
See this blog about how to upgrade to the new tiers and some advice on finding the right fit.
http://azure.microsoft.com/en-us/documentation/articles/sql-database-upgrade-new-service-tiers/
Basic is not equivalent to Web in the new Editions tiers. While you do 'upgrade' to editions, granting you access to new features and the tiers themselves, you can now choose an experience which has less performance than you had previous in Web/Business.
Try upgrading your server to a new tier based on the advice in the article above. If you read the article below:
https://msdn.microsoft.com/en-us/library/azure/dn369873.aspx
You can see that standard is actually targeting at many of the production use cases of Web, where Basic is targeting developers who were using Web, before, to test out their applications. Basic isn't intended for scenarios with multiple concurrent users.
Hopefully that helped. If you have any other questions, feel free to reply.
Regards,
Chris
