ISV embedding database with one instance per server limitation

Hi All,
As an ISV, it would be nice for Oracle to provide a better embedding solution than a silent install then having to script the creation of, or restore the database. Not because it's too complicated for an ISV to script, but purely for speed reasons. It's much faster to copy pre-loaded data files onto a machine than to create empty data files, load the data in, perform an analyze and any other scripts on the database. Dems just my thoughts.
However, my real issue is regarding the 'one instance per server' install limitation. As an ISV, if I choose to embed Oracle XE in my application - how can I 'guarantee' that my product can be installed on any given server. Picture this:
- We submit a proposal/ tender for a license to our software.
- Client, in conjunction with their IT dept adds internal costs, identifying servers that will run on, responsibilities, project plans (the whole works) etc.
- Client gets signoff from their management and pays for license.
- Client goes to install our software using Oracle XE just to find that another ISV has their software with Oracle XE embedded installed on the server.
- Client either has to find/ buy another server, or we lose the license. Either way, client is unhappy.
Am I missing something here? Is anyone else anticipating this problem?

Hi Florin,
Thanks for the response.. a good suggestion and our schema would be < 1GB so size would hopefully not be a problem. However, as soon as we plug into another appliation's Oracle XE implementation - we've potentially lost control of the database and it loses it's "embedded" nature. Probably not a huge problem if it's an application independant implementation of Oracle XE by an IT person, but if it's another ISVs embedded database - the dramas could start.
We effectively put our user's database within the control of another application who may not have considered the possibility of our data residing there. eg. They could do a 'drop-all' and we lose our database. Or tune the database right down and our application suffers. Or the user uninstalls that application and it decides to automatically remove Oracle XE (after all, that ISV thought it was an embedded application, right?). Do you see the potential issues?
Perhaps Oracle XE isn't as attractive for ISVs as first thought... I guess at the heart of the issue is the fact that Oracle XE isn't really an embedded database. It's just a database you can [silently] install with your application and then becomes a general db on the machine.

Max number of instances per Server

Good morning,
I've installed Oracle9i in a Windows 2000 Server with 1GB of memory. After that I've created several instances of Oracle DB. With 3 instances my server works acceptably, but after adding two mor instances I've begun to have some perfomance problems and the access speed has considerably decreased, so my question is, what is the maximum number of instances that the same Oracle server can support in order to optimize the access to the DB?
Thanks in advance.

Hi,
I am confronted with a similar problem. ie, we have got several instances on the basis of one application/one instance. I am asked to regroup all these instances to one and only one instance containing several schemas to reduce the number of servers, number of instances and on the way reduce the administrative ( dba ) tasks. As i have got some knowledge of dba, I thought of installing this instance under Oracle 10g like this : an application on its own tablespace and the backup of this tbs via rman. So when an application crashes, I can make use of TSPITR to bring the database to its initial ( stable ) status. My questions are :
1° any re-initialisation of the database will sanction all the schemas. Is there any
way to avoid this ?
2° as different tablespaces be brought to a consistency status different in time via
TSPITR even if the controlfile happens to be the same ?
3° if I opt for UNDO management AUTO, there can be only one UNDO TBS
active at a time. As this won't render me to trouble when i need to recover
only one application ? or on performance ?
Any prompt reply will be greatly appreciated.
Best regards.

Trying to restore a database with RMAN in new server

Hello,
Database: Oracle 10gR2
O/S: Windows Server 2003
My RMAN backuppieces are stored in a network drive:
\\old_location\FULL
and
\\old_location\INC
I'm trying to restore a whole database with RMAN in another server from my FULL backup.
For that, I copy all backuppieces files
from: \\old_location\FULL
to new server: D:\new_location\
Also I created the relevant folder hierarchy under <ORACLE_BASE> directory, as follows:
a. Create BDUMP, CDUMP, and UDUMP directories under '<ORACLE_ BASE>\admin' directory
b. Create <DATABASE_NAME> directory under '<ORACLE_BASE>\oradata' directory
c. pfile.ora and controlfile (CTL_MTDPROD_2308_20120401_1.CTL) are backup from original database and they are in D:\new_location\
d. I copied pfile.ora and controlfile to folder: C:\oracle\product\10.2.0\db_1\database\
I started creating an instance in new server from scratch:
C:\>oradim -new -sid MTDPROD -intpwd mtdprod
C:\> SET ORACLE_SID=MTDPROD
C:\> rman
RMAN> connect target sys
RMAN> SET DBID=21692876873
RMAN> STARTUP force nomount PFILE=C:\oracle\product\10.2.0\db_1\database\init_mtdprod.ora
RMAN> restore controlfile from 'C:\oracle\product\10.2.0\db_1\database\CTL_MTDPROD_2308_20120401_1.CTL';
RMAN> alter database mount;
#Since I want to read my backuppieces from D:\new_location and not from \\old_location\FULL then I catalog and restore like:
RMAN> catalog start with 'D:\new_location\';
RMAN> restore database;

Questions:
1. RMAN still reads from old_location. The only way to avoid that would be deleting all files from \\old_location\FULL ?
2. The message "failover to piece handle=D:\new_location\...." indicates that that file is not usefull? I just copy them from old_location to new_location... how can they get useless?
I suspect there is something in controlfile that redirects to \\old_location\FULL\ and doesn't let to read from D:\new_location\
Please, advice.

You may want to check the output of RESTORE DATABASE PREVIEW command, which will just report which backup files it uses without actually restoring thhe DB.

Backing up DPM2012R2 Database with a different DPM Server

Hi,
is it still a recommended way to backup up a DPM 2012R2 database (-> pure SQL on the same Server) with another DPM2012R2 Server?
So just attach it and back it up (like in DPM2010)?
Or shall one always use dpmbackup.exe?
If supported / recommended is it possible to backup a DPM 2012SP1 database with a DPM 2012R2 Server?
Thanks in advance

Hi,
Using native DPM backup using D2D is fine for non disaster recovery scenario, otherwise D2T or D2D2T or using secondary protection is best. DPMBACKUP is non automated, so that is good for ad-hoc backups before major updates.
Scheduling native SQL backups is also viable solution.
If using Secondary DPM Server, both primary and secondary must be the same DPM versions including updates.

Will Itunes only communicate with one device per computer?

I get an invalid response from Itunes when my iphone4 is connected to Itunes. I also have a nano that connectes and is working properly. Will Itunes only work with one device per computer. I took the iphone to an apple store and it connects with itunes like it should. I have swapped cables and ports, and downloaded the latest version. Thanks for your help

It is mean to work with multiple devices, although not simultaneously. However I have had exactly the same issue with iTunes 10.7 and Windows7 and a new 16GB iPod touch on iOS6 just this week.
iTunes detects and displays the iPod classic fine, but won't find the iPod Touch when it is connected. The connection is working fine as the Windows OS can see the iPod touch, just not iTunes.
I had a 2nd PC, which has a copy of the iTunes on it and the same media collection - this PC immediately recognised the Touch, so I have gotten around this issue, although I suspect reinstalling iTunes on the original PC may have also fixed it - I have kept a copy of iTunes 10.7.exe so I can reinstall and avoid that POS V11.
I suspect iTunes gets tetchy about hooking in two devices.
Actually as a mostly Windows / Android user, I don't get why on earth do Apple force you to do everything via iTunes anyway? Seems crazy to me. I sort of like the way I can hook up the Android unit and just drag over the files I want without all the darn hoop jumping Apple wants me to do. Anyway... I digress.
So Not sure. Happy I found an easier solution than a reinstall of iTunes. Of course, using a 2nd (mirrored) PC might not be an option for you. Good luck. Wish I had a better / more useful suggestion for you.

Limiting MDB to one instance per cluster

I'm working on a Weblogic setup that has one cluster consisting of three servers. We have one queue in particular whose MDB does a lot of database access. We're running into locking problems with the database because Weblogic is running an instance of the MDB on each of the three servers at the same time and they are stepping on each other's toes.
          I would like to limit the queue so it only runs on one server in the cluster. The pool size for this MDB is set to "1". I thought this would limit the total number of MDBs to one, but apparently it limits it to one per server.
          Any idea what sort of configuration I need to make sure only one instance of the MDB exists in the cluster? Do I need to turn this into a distributed queue and do something with load balancing?
          Thanks,
          Matt

Thanks for the reply.
          I looked around and I couldn't find a way to target the MDB to a specific server. I can target the JMS server, but not a single MDB. The way I have it setup currently, the JMS server is targeted to one server in the cluster (non-migratable).
          How do I target a MDB to a specific server?
          Matt

Clustering w/ Multiple Instances per server

For performance reasons, we want to setup multiple instances of weblogic on each server in our cluster configuration.How is this handled in a cluster configuration? Is each instance considered another server in the cluster? Does each require its on IP address, or is a seperate port sufficient for each? Also, is there a way to configure the cluster w/o using multicast - there's issues with supporing multicast on our backend network.Thanks, Rick


Sure, if JVM uses native threads and the application itself is well-behaved
          concurrency-wise (very important!) it should be able to scale up on multiple CPUs.

CPU_COUNT when more than 1 instance per server

Hi,
I wonder if there is any drawback when we got few instances on the same server from cpu_count point of view.
This parameter is derived by all instances like they are alone so all control structures are allocated independetly but there is more
resource needed when many instances in place.
Could this be potencial bottleneck ?
Regards.

The last time I checked the guideline the maximum CPU busy rate should be 90%
Here's more info:
http://www.dba-oracle.com/t_high_cpu.htm
The advice on that page is not very good - the most important point is the quote from IBM, which highlights the fact that there is a difference between single-user and multi-user systems:
<blockquote>
+"This holds true in the case of a single-user system with no need to share the CPU. Generally, if us + sy time is below 90 percent, a single-user system is not considered CPU constrained. However, if us + sy time on a multiuser system exceeds 80 percent, the processes may spend time waiting in the run queue. Response time and throughput might suffer"+
</blockquote>
In fact, it's a bit silly to give a single figure for the point where you should be concerned about CPU utilisation. The best reference for discussion is Cary Millsap's book "Optimizing Oracle Performance" which discusses the impact of concurrency on queueing. Instability in performance varies with the number of CPU combined with the percentage utilisation, and the break point sets in around the following levels:
<blockquote>
4 CPUs: 67%
8 CPUs: 75%
16 CPUs: 87%
</blockquote>
Your observation, thought that the OP should not mess with the cpu_count parameter is sound. Perhaps the only parameters that he should worry about are the parallal_max_servers and processes parameters to ensure that no one instance is allowed to run up more processes than the machine can handle.
(I find the best sources of information that bridge the gap between Oracle and the hardware are Kevin Closson's blog, James Morle's website - and a site from someone at Sun whose name I can't remember at the moment.)

Delivery from sales scheduling agreement with one item per schedule line

Hi all,
I have a sales scheduling agreement where the same part number has 3 different JIT schedule lines and I need to create a delivery with 3 item lines: every item line of the delivery has to be referred to one schedule line of the scheduling agreement.
When I create the delivery with transaction VL10E it has only one item line and its quantity is the sum of the 3 schedule lines of the sales scheduling agreement.
I've tried to change the customizing of the User Role, choosing the Split Schedule Line = 2 ("One item per schedule line") but the delivery is created again with only one item line.
How can I solve this issue?
Thanks in advance for reply

Dear Alex
The SAP standard behaviour is that all schedule items with delivery date in the past have to be rescheduled anyway to one date and are combined therefore.
Partially this behaviour can be influenced in VL10* by 2 parameters in
the user role : Split per sched.line and Rule (delivery qty).
Please find below informations about these different parameters
"Split per sched.line propose you 3 Rule for creating one delivery item
per schedule line. In a delivery list in item view with multiple
schedule lines, you can decide for the same document item whether you
want to generate one delivery item per schedule line or whether you want
to deliver the cumulated quantity of the last schedule lines selected.
About rule for delivery quantity, the following rules are currently
implemented:
1. No cumulation
The open schedule line quantity to be delivered is the quantity at which
the list line is delivered.
2. Sum of all open schedule line quantities to be delivered that fall
before the chronologically latest date in the to field (following the
Deliv. creation date field) of the selection criteria.
3. Sum of all open schedule line quantities to be delivered whose
delivery creation date falls within the selection time frame (between
the dates in the Deliv. creation date and to fields, respectively),
making the calculation of the quantity to be delivered consistent with
selection criteria. However, calculationof the quantities delivered with
the order's schedule line quantities is not affected."
Hope this helps.

Best Practice for VPC Domain failover with One M2 per N7K switch and 2 sups

I Have been testing some failover scenarios with 4 nexus 7000 switches with an M2 and an F2 card in each. Each Nexus has two supervisor modules.
I have 3 VDC's Admin, F2 and M2
all ports in the M2 are in the M2 VDC and all ports on the F2 are in the F2 VDC.
All vPC's are connected on the M2 cards, configured in the M2 VDC
We have 2 Nexus representing each "site"
In one site we have a vPC domain "100"
The vPC Peer link is connected on ports E1/3 and E1/4 in Port channel 100
The peer-keepalive is configured to use the management ports. This is patched in both Sups into our 3750s. (this is will eventually be on a management out of band switch)
Please see the diagram.
There are 2 vPC's 1&2 connected at each site which represent the virtual port channels that connect back to a pair of 3750X's (the layer 2 switch icons in the diagram.)
There is also the third vPC that connects the 4 Nexus's together. (po172)
We are stretching vlan 900 across the "sites" and would like to keep spanning tree out of this as much as we can, and minimise outages based on link failures, module failures, switch failures, sup failures etc..
ONLY the management vlan (100,101) is allowed on the port-channel between the 3750's, so vlan 900 spanning tree shouldnt have to make this decision.
We are only concerned about layer two for this part of the testing.
As we are connecting the vPC peer link to only one module in each switch (a sinlge) M2 we have configured object tracking as follows:
n7k-1(config)#track 1 interface ethernet 1/1 line-protocol
n7k-1(config)#track 2 interface ethernet 1/2 line-protocol
n7k-1(config)#track 5 interface ethernet 1/5 line-protocol
track 101 list boolean OR
n7k-1(config-track)# object 1
n7k-1(config-track)# object 2
n7k-1(config-track)# object 5
n7k-1(config-track)# end
n7k-1(config)# vpc domain 101
n7k-1(config-vpc-domain)# track 101
The other site is the same, just 100 instead of 101.
We are not tracking port channel 101, not the member interfaces of this port channel as this is the peer link and apparently tracking upstream interfaces and the peer link is only necessary when you have ONE link and one module per switch.
As the interfaces we are tracking are member ports of a vPC, is this a chicken and egg scenario when seeing if these 3 interfaces are up? or is line-protocol purely layer 1 - so that the vPC isnt downing these member ports at layer 2 when it sees a local vPC domain failure, so that the track fails?
I see most people are monitoring upstream layer3 ports that connect back to a core? what about what we are doing monitoring upstream(the 3750's) & downstream layer2 (the other site) - that are part of the very vPC we are trying to protect?
We wanted all 3 of these to be down, for example if the local M2 card failed, the keepalive would send the message to the remote peer to take over.
What are the best practices here? Which objects should we be tracking? Should we also track the perr-link Port channel101?
We saw minimal outages using this design. when reloading the M2 modules, usually 1 -3 pings lost between the laptops in the diff sites across the stretched vlan. Obviously no outages when breaking any link in a vPC
Any wisdom would be greatly appreciated.
Nick

Nick,
I was not talking about the mgmt0 interface. The vlan that you are testing will have a link blocked between the two 3750 port-channel if the root is on the nexus vPC pair.
Logically your topology is like this:
| |
| Nexus Pair |
3750-1-----------------------3750-2
Since you have this triangle setup one of the links will be in blocking state for any vlan configured on these devices.
When you are talking about vPC and L3 are you talking about L3 routing protocols or just intervaln routing.
Intervlan routing is fine. Running L3 routing protocols over the peer-link and forming an adjaceny with an router upstream using L2 links is not recommended. Teh following link should give you an idea about what I am talking here:
http://bradhedlund.com/2010/12/16/routing-over-nexus-7000-vpc-peer-link-yes-and-no/
HSRP is fine.
As mentioned tracking feature purpose is to avoid block hole of traffic. It completely depends on your network setup. Don't think you would be needing to track all the interfaces.

Problem with one computer: [RegTask] - Server rejected registration request: 3

Hi!
I having some problem with One of our clients, its mine :)
It does not register with the site
ClientIDManagerStartup.log:
MP_RegistrationManager.log
I have no idea why! I don't even use https and PKI. I have done a reinstalled the client by removing "C:\windows\SMSCFG.ini" and the SMS certificates before install but it still won't register. CCMSetup logs return successfull. Boundaries is setup
correctly.
I have also tried to uninstall ccmagent and readded the computer object in SCCM and installed it through client push but still the same problem.
I really don't want to reinstall the whole computer as I have already installed lots of applications i don't know if that will work anyway, could try to run a sysprep maybe.
Any ideas?
Thanks!

Multiple instances per server

Back in January, I talked to Oracle about multiple instances on NT. They said I could do it but not recommended for production.
Finally received the 11.5.3 cd kit so getting ready to do the upgrade on development. In looking at the "upgrading" chapter of the "install" guide, the panel displays only show information for one instance!!! How do I enter information for other instances including a new demo database. Back in January, I was told I could share the appl_tops.
