Re: Oracle 10g Data Migration

[Ramey, Anne]

We recently did this with the export/import method for a 700G DB and it took, 
all in all about 24 hours.  We've done it using backups before, and as long as 
your systems match exactly for disks and space this can be faster (~12 hours).

There are many ways to perform this task. To name a few:

1) perform a cold backup of the database -> copy to new server
2) export/import
3) using data pump
4) using oracle's database creation assistant (DBCA)

My recommendation is, if you are not familiar with these terms/tools.
Find a DBA. What version of Oracle are you going from to?

Does anyone know approximately how long will it take to replicate a 
database server of 600gig of data to another Oracle server box? And 
what's the best tool out there to make that feasible quick and easy?

Re: SRM 7.6 - Your experiences?

[Ramey, Anne]

I agree 7.6 is easier and put together more effectively that previous versions, 
even 7.5.  I upgraded with no issues and they have fixed most of the issues we 
saw in the previous version.

We have upgraded to SRM 7.6.03 on our test server and realised that users with 
Work Order Manager permissions can no longer update any work order, but only 
those assigned to their group.
Rather annoying as there seems to be no other role/permission allowing access 
to any work order irrespective of the assignment.
Anybody else noticed this?

Load Balancers and how?

[LJ LongWing]

Ok..I'm going down a road that I KNOW some of you have travelled before, I
need your travel tips.  We are setting up a server group on 7.5 Windows and
we are putting a load balancer in front of it.  How do you all tell if a
node is up?  There are 4 types of probes that I'm being told are available.

 

PING

HTTP

TCP

Script

 

Ping  - Obviously doesn't tell you anything other than the host OS is up

HTTP - Won't work for telling if a remedy service is up

TCP - My instincts are telling me that this one simply does something
similar to a telnet to a given port, if the port allows you 'in', then the
service is considered up.  I don't consider this one viable because it
doesn't 'test' much and I expect that my remedy server could respond to the
port request without actually being functional

Script - This one is the most promising in my mind, but I know nothing about
the scripting language of TCL.

 

How does the rest of the remedy world 'verify' that their remedy instance is
online so that their load balancer can know to route traffic to it or not.
I just this week finished a java servlet that allows the mid tier load
balancer to know if an individual node is working properly, but the same
can't be said yet for Remedy..any and all help is appreciated

Roger,

What method did they use to determine it was started/running?  I personally 
have found ‘other teams’ don’t usually have a concept of what ‘functional’ 
means in a remedy world.  I don’t consider the fact that arserver.exe is in 
memory an indicator that my server is functional…I’ve had TOO many situations 
where it was in memory, but you couldn’t log onto it.

Re: Load Balancers and how?

I provided the best information and then let the customer determine how they 
can monitor the system with the LB. I agree that both Mid-Tier and App Servers 
have issues with finding if the system is truly available. I know that the 
files arerror and armonitor can assist with this.

Recommendations for Load Balancers and Mid-Tier Servers

[Pruitt, Christopher (Bank of America Account)]

Hello All,

We are in the discovery process for setting up some new mid-tier servers. We 
are looking at standing up some HP ProLiant DL380 G6 Servers and am seeking 
some recommendations for Load Balancers. Anyone have some suggestions for some 
good load balancers for these servers?

Re: Load Balancers and how?

[Danny Kellett]

Hi,

 

PING - Most firewalls don't allow ICMP traffic.

HTTP - You can use this, with a formed url including a user name and pass,
to use on the load balancer in front of the midtiers not the AR Servers.

TCP - I have found that even though you can connect on the TCP port, it
doesn't always mean its responsive e.g. ARERR 91 to 93 Reason being is that
you don't connect to arserver.exe, you connect to arforkd

Script - I don't know TCL but if you can run an executable, then you could
have driver which is always installed in the AR Server dir and you could
feed in a driver script with -x.

 

Regards

Danny

Re: Load Balancers and how?

The LB itself should be able to determine that if it is configured correctly.  In particular on Apache you would use mod_proxy and mod_proxy_balancer modules simultaneously with some ProxyPass directives defined. Any of your web server admins should have a very good idea of what I am talking about. If I were not typing this from my obnoxious touchscreen I would go into more detail. In any case if you need more precise help reply stating so and I will be happy to help on e I get to my desk.Cheerios!Sent from my Windows Phone

Re: Recommendations for Load Balancers and Mid-Tier Servers

[Roger Justice]

**
Be sure what ever LB you are reviewing has the ability to invoke a sticky bit. I have encountered users that did not do this and of course they had issues such as a challenge to login when a save is done since the session has moved from one server to another.

Re: Recommendations for Load Balancers and Mid-Tier Servers

[Danny Kellett]

Hi,

 

It should be server agnostic. The questions you should be asking is how much 
money do you have, what is your concurrent load, what type of ports do they 
have,  what method do they use RR, Least Connections, Weighted, Fastest 
Response time etc

 

If you want high end then I have worked with F5 but there are Cisco, Foundry, 
Nortel

Danny

Re: Load Balancers and how?

[Shellman, David]

LJ,

Here are a few approaches that can be used.

A product called SiteScope can be configured to access a form through the 
MidTier.  This gives you end to end up/down information.

We also use HP OpenView to monitor the services on the MidTier, app and 
Database servers.  We also monitor the arerror, stderr.log and stdout log files 
on the app server, the Oracle logs on the DB server and the MidTier log files 
on the MidTier servers.

I have also created a health check for email services.  This simply sends an 
email out of the system to one of two email addresses we use for incoming 
ticket generation.  The email creates a record in a receiving form that when 
the record is created updates the record on the sending form.  If the record on 
the sending form does not generate within a specific time period an escalation 
will send us email and page us.

Dave

OkI'm going down a road that I KNOW some of you have travelled before, I 
need your travel tips.  We are setting up a server group on 7.5 Windows and we 
are putting a load balancer in front of it.  How do you all tell if a node is 
up?  There are 4 types of probes that I'm being told are available...

PING
HTTP
TCP
Script

Ping  - Obviously doesn't tell you anything other than the host OS is up
HTTP - Won't work for telling if a remedy service is up
TCP - My instincts are telling me that this one simply does something similar 
to a telnet to a given port, if the port allows you 'in', then the service is 
considered up.  I don't consider this one viable because it doesn't 'test' much 
and I expect that my remedy server could respond to the port request without 
actually being functional
Script - This one is the most promising in my mind, but I know nothing about 
the scripting language of TCL.

How does the rest of the remedy world 'verify' that their remedy instance is 
online so that their load balancer can know to route traffic to it or not.  I 
just this week finished a java servlet that allows the mid tier load balancer 
to know if an individual node is working properly, but the same can't be said 
yet for Remedyany and all help is appreciated

We have implemented load balancing effectively at SSB; two web servers 
(remwebprod), two app servers (itsmappprod), SQL2008 DB server with 
replication.  Internal application references must use the aliases and not 
physical server names or IP.

Re: Load Balancers and how?

[Axton]

You will want to handle traffic for both rpcbind and arserver, and
potentially your plugin servers, DSO, on the LB, depending on your
implementation.  The easiest check is just a port check.  I think most LB
devices provide this capability.  As you recently saw with your
Mid-Tier/Tomcat problems, a simple port check does not always fault the node
if there is a problem.

What kind of device are you using to balance the traffic?  If you are using
an F5 LTM, iRules can be written to do more extensive checks.

I was part of a thread on the subject here that can provide some additional
information:

There are many ways to perform this task. To name a few:

1) perform a cold backup of the database ->  copy to new server
2) export/import
3) using data pump
4) using oracle's database creation assistant (DBCA)

My recommendation is, if you are not familiar with these terms/tools.
Find a DBA. What version of Oracle are you going from to?

Issue with Multi Tenancy and Interface forms

[Chowdhury, Tauf]

All,
I just submitted this as an issue but I wanted to see if any of you tested or 
ran into this. I'm in SRM 7.6 training and the issue is still present. I 
apologize in advance if my scenario is confusing but it's the best way I could 
describe the issue!

Here is the scenario and you can test it out in your environments:

1. Joe User on the People form is part of Company A. (Field ID on people form: 
11).
2. In the Access Restrictions on the People Form, Joe User has Company A and 
Company B in his Access Restrictions table. Joe User does not have Unrestricted 
Access. Joe is a part of support groups in both companies (irrelevant).
3. An Incident Template is created for users in Company B and the Product 
Catalog Entry that is used is a categorization specific to Company B. 
4. Now, an SRD is created for Company B using a PDT and AOT with the Incident 
Template from #3 related to it. 

SO far, so good.

5. Joe User goes to Request Entry and because he is a part of both Company A 
and Company B, he can request the Company B service. 

Still good!

6. After hitting Submit, however, the Fulfillment Incident is never created and 
the error is that the Product Categorization is invalid. 

Upon further investigation, I have found that this is because on the Incident 
Interface form, there is workflow that looks up Joe User on the people form and 
uses field ID 11 from the people form to fill in the Company field on 
the Interface form. Because of this, the Company is set to Company A which 
doesn't have access to the Product Catalog entry which is specific to Company 
B. 
I have tried to hard code the Categorizations and Company on the PDT but this 
does not work.

I am not sure if this is issue has been corrected in 7.6.03/04 but it is 
definitely a show stopper when it comes to segregating data.

Apache does a very excellent job as long as it is properly configured alongside Tomcat and as well setup on scalable hardware. Apache is just as corporate as any other software option and it is not the most widely used web server because it can't perform, right :-D?? Going cheap is just one of the benefits of using Apache and not one of the caveats. Apache does an amazing job dealing with large scale connections from end clients.

Re: Load Balancers and how?

[LJ LongWing]

The problem is that load balancers are only as smart as their implementation.  
We have been running for years with our load balancer checking a static html 
file on the tomcat server….while this provides a check of ‘is the tomcat server 
working’, it does not provide a check of ‘is the mid-tier application 
functioning’….so I respectfully disagree that the lb or the lb team know how to 
configure it properly.  We are using Cisco’s CSM (Content Switching Module), 
and I don’t want to just rely on a port probe because I don’t trust that it 
means I’m functional.

The LB itself should be able to determine that if it is configured correctly.  
In particular on Apache you would use mod_proxy and mod_proxy_balancer modules 
simultaneously with some ProxyPass directives defined. Any of your web server 
admins should have a very good idea of what I am talking about. If I were not 
typing this from my obnoxious touchscreen I would go into more detail. In any 
case if you need more precise help reply stating so and I will be happy to help

Dave,

I also have similar monitoring on the app/db/web servers.but that doesn't
solve the problem of having two app servers with a load balancer sitting in
front of them, and ensuring that if node 1 goes offline, that the load
balancer will stop sending traffic to it.that's what I'm needing.

Here are a few approaches that can be used.  

 

A product called SiteScope can be configured to access a form through the
MidTier.  This gives you end to end up/down information.  

 

We also use HP OpenView to monitor the services on the MidTier, app and
Database servers.  We also monitor the arerror, stderr.log and stdout log
files on the app server, the Oracle logs on the DB server and the MidTier
log files on the MidTier servers.

 

I have also created a health check for email services.  This simply sends an
email out of the system to one of two email addresses we use for incoming
ticket generation.  The email creates a record in a receiving form that when
the record is created updates the record on the sending form.  If the record
on the sending form does not generate within a specific time period an
escalation will send us email and page us.

Roger,

What method did they use to determine it was started/running?  I personally
have found 'other teams' don't usually have a concept of what 'functional'
means in a remedy world.  I don't consider the fact that arserver.exe is in

How does the rest of the remedy world 'verify' that their remedy instance is

Re: Load Balancers and how?

[LJ LongWing]

Axton,

We are using Cisco's CSM as a load balancer.  I'm surprised in this day and
age, with remedy being around as long as it has been that we are having this
discussion, but reading a post you made in that thread

 

'Another option I am considering is writing a program to listen on a port
separate that of the application that can handle a request that contains a
string. It would simply return a 0 or a 1 if the server is up or down.'

 

I was just considering an option along those lines.  To save me some time
and maybe help the community, do you by chance have that daemon written?
(you did write that post over a year ago)

 

If not, I may need to pull out my eclipse (YET AGAIN) to solve load
balancing issues in my environment.

** You will want to handle traffic for both rpcbind and arserver, and
potentially your plugin servers, DSO, on the LB, depending on your
implementation.  The easiest check is just a port check.  I think most LB
devices provide this capability.  As you recently saw with your
Mid-Tier/Tomcat problems, a simple port check does not always fault the node
if there is a problem.

 

What kind of device are you using to balance the traffic?  If you are using
an F5 LTM, iRules can be written to do more extensive checks.

[Axton]

What I was working on at the time is available here:

http://communities.bmc.com/communities/docs/DOC-9059

This is a command line
utility that will checks the availability of the server by issuing an
ARVerifyUser call to the server.  I was planning to take this and wrap it in
something to make it available over the network, like a cgi, or maybe if
there is a good tiny http server, embedding that into the project.

A product called SiteScope can be configured to access a form through the
MidTier.  This gives you end to end up/down information.

We also use HP OpenView to monitor the services on the MidTier, app and

Recommendations for Load Balancers and Mid-Tier Servers

[John Baker]

Rich,

Apache is arguably the most widely used web server in the world, and
does a great job of load balancing.  I've done a lot of work for
investment banks that can only be described as "very corporate", and
Apache has been a key component in their infrastructure.

The problem with Apache and Midtier is mod_jk.  I wrote an article on
this last week.

Re: Recommendations for Load Balancers and Mid-Tier Servers

[Gard, Richard J]

Hi John,
I did not mean to disparage Apache LB solutions.  It clearly has its place and 
will serve well.  I use them for lab work when I need to test a solution behind 
an LB.  It all depends on your corporate standards, DNS and IP management, 
business continuity plan, cross datacenter failover and the like.  I have never 
thought of using Apache LB outside the lab.  I am not sure if it is even 
allowed here.  However, our corporate LB is now brand XXX (don't really care 
what it is because that is what I am supposed to use).  I have used Apache, F5, 
LD, CSS and DD. Being a user, I never needed to build my own LB using Apache 
for a production Application with critical importance. I use what the network 
guys say I should use.  They register the aliases, define the VIPs, and 
support/config the infrastructure devices.

Yes..so I guess the question then would be

administrator can create a "script probe" that the Cisco CSM periodically
executes for each real server in any server farm associated with the probe.
Depending upon the exit code of such a script, the real server is considered
healthy, suspect, or failed. A wide variety of probing functions are
possible using the flexibility of the TCL scripting environment. The Cisco
CSM also supports execution of custom TCL scripts that are not directly
associated with a particular server health probe. A "standalone script"
dynamically executes a task at a specified interval."

I'm not seeing that capability of the Cisco CSM unfortunately.

Some Load Balancers are able to snmp checks.  I've found that this works
pretty well with arsnmpd.

Dave,
I also have similar monitoring on the app/db/web servers.but that doesn't
solve the problem of having two app servers with a load balancer sitting in
front of them, and ensuring that if node 1 goes offline, that the load
balancer will stop sending traffic to it.that's what I'm needing.

LJ,

Here are a few approaches that can be used.

A product called SiteScope can be configured to access a form through the
MidTier.  This gives you end to end up/down information.

We also use HP OpenView to monitor the services on the MidTier, app and
Database servers.  We also monitor the arerror, stderr.log and stdout log
files on the app server, the Oracle logs on the DB server and the MidTier
log files on the MidTier servers.

I have also created a health check for email services.  This simply sends
an email out of the system to one of two email addresses we use for
incoming ticket generation.  The email creates a record in a receiving form
that when the record is created updates the record on the sending form.  If
the record on the sending form does not generate within a specific time
period an escalation will send us email and page us.

Dave

Roger,
What method did they use to determine it was started/running?  I personally
have found 'other teams' don't usually have a concept of what 'functional'
means in a remedy world.  I don't consider the fact that arserver.exe is in
memory an indicator that my server is functional.I've had TOO many
situations where it was in memory, but you couldn't log onto it.

if the Remedy Service was started/running.

Ok..I'm going down a road that I KNOW some of you have travelled before, I
need your travel tips.  We are setting up a server group on 7.5 Windows and
we are putting a load balancer in front of it.  How
