Disk and tempdb configuration for multiple Instances in one SQL cluster

Hi Everyone ,
I am in planing to build SQL Cluster on Blade server . Two blades are allocated for SQL. and planning to cluster those two blades. It will be windows 2012R2 and SQL 2012/2014. Initially it was plan to put most of database on one SQL instance. but
due to other requirements I will be Installing more SQL Instance on same cluster.
for now Everything will be on RAID 10 but do not have more details about storage yet that how it will get configured
256 GB Ram on Each blade server.
1) what are the Disc configuration recommendation for data and log files when each instance get added?
2) what are the Disc configuration recommendation for tempdb files when each instance get added?
3) Each Instance Tempdb file on Same drive is good practice?
Any other Best practices should follow for this setup?
Thank you ....

1) what are the Disc configuration recommendation for data and log files when each instance get added?
Keep both the sql instances in diffèrent drives.read the below link for RAID levels and according to your usage you can cofigure it..

Storage best practice.
http://technet.microsoft.com/en-us/library/cc966534.aspx
2) what are the Disc configuration recommendation for tempdb files when each instance get added?
Its good to have sepreate drive for tempdb and each instance too with correct allocation or configuration..RAID5
for data if you must, but have to keep a spare drive around for that.
Best is 10 everywhere. If that's too expensive, then 1 or 10 for log and 5 for data (and 10 for TempDB)
RAID 5 is terrible for logs because it has a high write overhead. Tran logs are write-heavy, not read-heavy.
3) Each Instance Tempdb file on Same drive is good practice?
Tempdb configuration is depends, its completelty based on your server and tempdb usage..Make sure to have equal size for all the files in tempdb, As a general rule, if the number of logical processors is less than 8, use the same number of data files
as logical processors. If the number of logical processors is greater than 8, use 8 data files and then if contention continues, increase the number of data files by multiples of 4 (up to the number of logical processors) until the contention is reduced to
acceptable levels or make changes to the workload/code.

Dynamic memory allocation on HP-UX for multiple instances on one host

Hi everyone,
I was wondering what the current possibilities are nowadays on running multiple SAP instances on one very large host with regard to resource sharing. Normally, for each instance, using PHYS_MEMSIZE etc you have to set the memory to a fixed size and then optimize it.
Preferrably we would like the memory to be allocated based upon actual usage. Is that possible at all? on HP-UX? Using third party techniques?
Thank you
Marcel Rabe

Hello Marcel,
As Juan said you may not be able to change the parameters at runtime.
The only parameters that can be dynamically switched are :
ztta/roll_first
ztta/roll_extension
ztta/roll_area
abap/heap_area_dia
abap/heap_area_nondia
abap/heap_area_total
em/stat_log_size_MB
em/stat_log_timeout
These parameters would put a cap on memory allocations, however they wouldn't help increase the total addressable memory area.
I would suggest that you consider Adaptive Computing for dynamic use of resources.

Sappfpar for multiple instances in one host

hi,
There are 3 sap instances are running on one of my host. If I use sappfpar check <instance profile>, it gives what would be the worst case memory requirements..
Is there any way to check for all 3 instances together for memory requirements? Should I run one by one and add all together for total requirements ?
Thanks,
RajS

Hi,
Could you please check the settings
Goto: SCCL try with these options and check for the relevant sap notes available in service market place

HT3622 I need different facetime and messenger details for multiple ipods on one apple id how do I do this when in itunes?

I have an iphone and my 2 children have Ipod touch they have to be set up under my apple id to be able to purchase apps. But we all want to have separate facetime & messenger accounts. My contact list seems to have appeared on one of my childs ipod touch. How can I set up separate accounts but under one apple id.

Answers that I know :
a, yes - I have an iPad, iPhone, and iPod Touch linked to my account on the same computer/iTunes and haven't had any problems with it
b, you only need to purchase the app once, it can then be copied onto all your devices. Some of my apps are on all three of my devices. If you get newspapers or magazines then I believe that some only allow one download of each magazine/newspaper, so you may not be able to have them on each device.
c, as long as you have your own Game Center accounts then you should be able to - I've never used it
d, yes, you can have them on all your devices, you don't need to multi-purchase them
e, I think that you will each need your own email address for them - in Settings > iMessage you can link an email address with messaging, and similarly for FaceTime (Settings > FaceTime) - that way messages/calls will only go to the correct person. Using FaceTime ; there is also some info on the built-in apps in iPad's manual and iPod's manual
f, all content purchased via an iTunes account is tied to that account, and they cannot be copied or transferred to a different account. So any content purchased on your wife's account will remain tied to her account. You can have more than one iTunes account authorised on a computer's iTunes (Store > Authorise This Computer), so you can have her content as well as yours on the computer that you sync to.
g, don't know, I've not made any in-app purchase
h, with the device connected to and selected on the left-hand side of your computer's iTunes, then on the tabs on the right-hand side you can control what is synced to that device. Those selections should then be remembered each time you re-connect that device, so you can have different selections for each device and you shouldn't have to re-do the selection each time you connect it.

Define Tabs and Process Configuration for Template

Hi All
I would like to give the local HR the ability to define Tabs and Process Configuration for Template
The only way I can find to create these definitions is using SPRO and I don't want to give HR users SPRO
Is there a transaction which will allow the HR users to define Tabs and Process Configuration for Template?
Thanks
Maya

You can try this URL:
http://server.domain:port/sap/bc/webdynpro/sap/hap_configuration?WDCONFIGURATIONID=HAP_AC_TAB_CONF
Just change server, domain and port to match your SAP instance.

Using .vit for multiple instance

Hi,
I have a main vi, uses rendevous to run multiple subvis at the same time, that needs to be opened separately per user which need to open the same vi multiple times.
I tried to use .vit, changed main vi to vit. Created new vi that calls this main.vit. However this doesn't run multiple times, only opens the first window. Then I used subVIs as vit. This even creates a bigger problem. The sub vi's that opened doesn't run.
I think I'm missing some basic concepts of using vit. I searched the forum, found some articles but I can't find what I'm doing wrong.
Should main vit calling several sub vit's work?
Any tips, comments would help.
Thank you very much.

"CoastalMaineBird" <[email protected]> wrote in message news:[email protected]..
VIT is not for multiple instances, it is a TEMPLATE. That means you open it up, but when you go to save it, it pretends that it's untitled, and you have to give it a new name.
That's useful - for example, I have a TIMING TEMPLATE. When I want to time something. I open this VIT file. I insert the code I want to time into a certain frame, and run it. I usually don't save it, but if I do, I have to give it a new name.
That way, the next time I open it, it's fresh again.
If you want to run the same VI multiple times in parallel, you must:
- Understand what RE-ENTRANT EXECUTION means.
- Set the VI to use re-entrant execution.
- Use the VI Server to open each instance dynamically.
- Use the VI Server to CLOSE each instance dynamically.
- Be very careful about getting data into and out of the VI in question.
HTH
VI Templates can also be used to run multiple instances of the same vi. If you open a .vit dynamically several times, you'll end up with several instances of the vit. Actually, this is an intended use of the vi templates. And it works great. The great benefit over reentrant vi's is that the vi templates have front panels of there own. So it's great to use vit's when you want several similar panel, without copying the code. Reentrant vi's where not intended for this. Before 8.0, reentrant vi's didn't even have panels that updated properly, so you had to use a vit.

How to execute a MTS (Master Test Script) in SAP ECATT Test Configuration for multiple variants.

I have a MTS (Master Test Script) which references 4 Test Scripts. As of now, I am able to run this MTS directly by opening it as a Test Script and running it for default test data.
Now, I want to run this MTS in SAP ECATT Test Configuration for multiple variants/test data. I am not able to see any parameter if I enter MTS in the Test Configuration.
Below thread is similar to my requirement but I am not able to understand the solution properly.

SSL and Credentials configuration for webas

Hi..
I got a doubt in SSL certificate configuration.When i need to configure a JAVA engine for activating SSL.I would create .CSR and get signed from Trust center which inturn gives three certificate root,intermediate and original certificate and so we can configure the JAVA URL as https://<hostname>:<port no>:500001/...
Now the same can also can be configured for ABAP WEBAS engine.my doubt is as per note : 510007,SAP has said to generate .PSE file and SSL configuration which will work in 443 port and HTTPS port as in SMICM transaction
But I have two instances running on single host.I have already configured HTTPS 443 for one instance say for ABAP webas.And If i need to configure for another instance, can i change the HTTPS port as per my requirement ????,because 443 has been assigned to another instance (earlier) .And Can i generate PSE file from that new port and get the certificate installed that is obtained from Trust center ???
Expecting you Ideas and solution for this scenario..
Thanks
Gopalakrishnan M

Hello Gopalakrishnan,
To specify the https port of ABAP, you can use paramenter
icm/server_port_<X> as PROT=HTTPS,PORT=<port>
I think the default port for http is like below
icm/server_port_0 as PROT=HTTP,PORT=80<instance_number>
Then you can just specify icm/server_port_1 for https.
Good luck,
Victor

Can I set up multiple usb hard drives- one for time machine and a second for media? Can one also print wirelessly with an old HP C6280 printer?

Can I set up multiple usb hard drives- one for time machine and a second for media?
Yes.
Can one also print wirelessly with an old HP C6280 printer?
Possibly by using an Airport Express, but depends on what type of port connection the printer requires.

Define Tabs and Process Configuration for Template (HAP_TA_CONF)

I am currently building a new appraisal template for my client and I have configured the process timeline in the development system via the IMG node Define Tabs and Process Configuration for Template (transaction code HAP_TAB_CONF).
Does anyone know how to transport the tabs and process configuration through the system landscape?
We are on SAP ECC 6.0 Enhancement Pack 4

Hi Sushil,
I have used the report RHMOVE30 as you recommended and it worked perfectly in one run. I did not have to create custom relationships. I simply selected all the Process Item (VH) objects for my appraisal template and ran the report.
Many thanks for your help. It has saved me having to configure the tabs and process timeline in each client.

How to find out CPU and memory usage for an instance?

Hi DBA Gurus,
How to find out CPU usage and memory usage for an instance?
Any information is appreciated!
Thank you!
Robert

you can calculate cpu usage by adding fallowing three factors which you can get from v$sysstat
1. Parse CPU time : This represents the percentage of CPU time spent parsing SQL statements. Parse time CPU can be a strong indication that an application has not been well tuned. High parse time CPU usually indicates that the application may be spending too much time opening and closing cursors or is not using bind variables.
2. Recursive CPU time : Sometimes, to execute a SQL statement issued by a user, the Oracle Server must issue additional statements. Such statements are called recursive calls or recursive SQL statements. For example, if you insert a row into a table that does not have enough space to hold that row, the Oracle Server makes recursive calls to allocate the space dynamically if dictionary managed tablespaces are being used.
Recursive calls are also generated due to the inavailability of dictionary info in the dictionary cache, firing of database triggers, execution of DDL, execution of SQL within PL/SQL blocks, functions or stored procedures and enforcement of referential integrity constraints
3. Other CPU time : This represents the percentage of time spent looking for buffers, fetching rows or index keys, etc. Generally, \"Other\" CPU should represent the highest percentage of CPU time out of the total CPU time used.
total memory used you can calculate adding
total_agrigate_area+sga
memory usage on os level you can know by fallowing commands
vmstat 5 20 depending upon os

Need to make automatic startup and shut down for the instance

hi to all
i have os : Red Hat lunix as 3 , woth oracle DB 10g 10.0.1
need to make an automatic startup and shut down for the instance when i start and shutdown the OS
i tried Use dbstart and dbshut scripts then created file dbora at dbora as a script
then i did
# ln -s /etc/init.d/dbora /etc/rc.d/rc3.d/K01dbora
# ln -s /etc/init.d/dbora /etc/rc.d/rc3.d/S99dbora
# ln -s /etc/init.d/dbora /etc/rc.d/rc5.d/K01dbora
# ln -s /etc/init.d/dbora /etc/rc.d/rc5.d/S99dbora
nothing worked
if you will attach me any files
my mail is :

Hi,
The /etc/oratab should have an entry for this database with 'Y' in the last field as:
Oracle_sid: Oracle_Home:Y, so when dbstart command issued it will check the oratab and starts the database.
I advise you to keep the dbstart and dbshut in different scripts and save them directly in the runlevel directories, instead of creating links.
thanks

Is it possible to combine multiple Pur Reqs for multiple materials to one vendor into one PO through MD07?

We have material planners who use MD07 (traffic signal screen) Stock/Requirements List, Collective Access tab to review material requirements by MRP Controller. Once the list is created, they select individual materials and review them in MD04. In a lot of cases, Purchase Reqs (PRs) are reviewed and adopted into POs individually for each material. Sometimes they will combine multiple PRs for one material into one PO. This is a good practice. However, from what I have found, it is not possible to combine multiple PRs for multiple materials into one PO. If this was done it would dramatically reduce the number of POs that we are issuing to suppliers. Problem statement: We issue too many POs which causes additional influxes down the line (receiving dock/goods receipts processing, receiving issues, invoices, invoice issues, etc.). Does anyone know of a way to address this problem without a major overhaul in approach or customization of the system? Thank you in advance!

Hello Michael
As far as I know, this is not possible directly from MD07, only from the MM transactions.
The following thread suggests the following procedure to convert several PRs into one PO:
Conversion of multiple PR into single P.O
Drag and drop the first PR from the item overview to the shopping card on top of ME21N,
then open the PO detail delivery schedule tab and drag and drop all other PR to the shopping card shown in the schedule tab
You can use the same procedure, calling the order conversion from MD07 and then drag and drop another PRs into this PO.
