Hi Deepak,
Here is another blog post containing some thought how it can be estimated.

First, it's totally impossible to answer in the abstract, see:
https://lucidworks.com/2012/07/23/sizing-hardware-in-the-abstract-why-we-dont-have-a-definitive-answer/

Second, indexing DB tables directly into Solr is usually the wrong
approach. Solr is not a replacement for a relational DB, it does not
function as a DB, is not optimized for joins etc. It's  a _search
engine_ and does that superlatively.

At the very least, the most common recommendation if you have the
space is to de-normalize the data. My point is you need to think about
this problem in terms of _search_, not "move some tables to Solr and
use Solr like a DB". Which means that even if someone can answer your
questions, it won't help much.

Solr server configuration

[Deepak Nair]

Hello,

We want to implement Solr 7.x for one of our client with below requirement.


1.   The data to be index will be from 2 Oracle databases with 2 tables 
each and around 10 columns.

2.   The data volume is expected to be reach around 10 million in each 
table.

3.   4000+ users will query the indexed data from a UI. The peak load is 
expected to be around 2000 queries/sec.

4.   The implementation will be on a standalone or clustered Unix 
environment.

I want to know what should be the best server configuration for this kind of 
requirement. Eg: how many VMs, what should be the RAM, Heap size etc.

Thanks,
Deepak

Yes, that's right, just make the path in the solr.xml is right, everything will 
be ok!

Hi,

 I tried as you said and got the result without any error. So we can make
the solr home anywhere. But we have to give the path correctly in solr.xml.
Am i correct?

 Now i am one step further.. :)

RE: Solr Server Configuration

[Kijiji Xu, Ping]

I'm sorry I don't quite understand why you create a folder named solr in 
tomcat/bin in your step 3
The first of all ,you should understand this solr.xml file which I put in 
tomcat/conf/Catalina/localhost/,its contents follows like this:

   


When tomcat was start,tomcat will read this file,and then,tomcat know that he 
should unzip the /home/tomcat/webapps/solr.war,deploy it ,you'll see a folder 
named solr in the tomcat webapps folder when tomcat be started at last.
And  means solr's home path is /home/solr, in the folder 
'/home/solr',it contains folder 'conf' with solr's configuration 
file:schema.xml and solrconfig.xml ,so at last file structure will be like this:

/home/tomcat/conf/Catalina/localhost/solr.xml
/home/tomcat/webapps/solr.war
/home/solr/conf/schema.xml
/home/solr/conf/solrconfig.xml

I attacked a home.rar file in this mail,it is solr's files in the tomcat 
directory structure,FYI

These are the steps i followed for the solr server working..

1. Used tomcat 5 with windows.
2. Deployed the war apache-solr-1.2.0 in to the webapp directory and rename
it as solr.war
3. Then i created one folder named solr in tomcat - > bin.
4. Copy the conf folder in example folder and placed that conf in the solr

RE: Solr Server Configuration

[nithyavembu]

Hi Kijiji Xu,

   Thanks a lot for your clear guidance. I tried as you said. But i was
unclear with the environment varible values in solr.xml  So atlast i didnt
touch the configuration parts.
These are the steps i followed for the solr server working..

1. Used tomcat 5 with windows.
2. Deployed the war apache-solr-1.2.0 in to the webapp directory and rename
it as solr.war
3. Then i created one folder named solr in tomcat - > bin.
4. Copy the conf folder in example folder and placed that conf in the solr
folder in tomcat bin.
5. Then start the server and and tried the url http://localhost:8080/solr/
in browser.

Is there anything wrong i did? If so please tell me..

V.Nithya.

The solr java client has actually been committed in the latest
development version, but is still subject to change.

When possible, prefer an external (HTTP) interface over an embedded
one, as it will likely remain more stable over time.

Re: Solr Server Configuration

[Tristan Vittorio]

If you are used to working with Lucene and want to interface Solr directly
from within a java application, you can take a look at DirectSolrConnection
from EmbeddedSolr, check the wiki page
http://wiki.apache.org/solr/EmbeddedSolr for more info.

Tristan

In java ,there have a class named org.apache.solr.util.SimplePostTool ,you
can look at the source code of it,and you'll know how it worked for posting
xml data to solr

ii) How can i send the http request n get response in a standalone java
program?
In my opinion, you can use the java HttpURLConnection class to request and
get response from the solr server

iii) Whether i have to add any xml or i have to modify the xml
(server.xml,web.xml) files for solr server configuration?
NO, but there have two type of configuration for solr .
First of all, the solr configuration file locate in the solr/conf,there
are solrconfig.xml and schema.xml ,you would change them for your
application .
Second, you have to deploy solr application itself to Tomcat, and you
would put a configuration file like this in the tomcat ,the path
is  /home/tomcat/conf/Catalina/localhost/:

   


That's all,if you have any question,feel free to ask me:)

RE: Solr Server Configuration

[Vince McNamara]

Hi Nithya

I'm new to this myself and I'm sure there are other ways to POST to solr but
here's one way. This uses the Apache commons HttpClient - downloaded from
http://jakarta.apache.org/commons/httpclient/
You need to change the first parameter to the StringRequestEntity
constructor to use a string containing your xml document.
I can't help with Tomcat configuration - I haven't used it for solr.


Cheers

Vince


HttpClient client = new HttpClient();
PostMethod method = new PostMethod("http://localhost:8983/solr/update";);
RequestEntity requestBody = new StringRequestEntity(xmlDoc.asXML(),
"text/xml;  charset=UTF-8","UTF-8");
method.setRequestEntity(requestBody);
client.executeMethod(method);
String response = null;
if (method.getStatusCode() == 200){
response = method.getResponseBodyAsString();
LOGGER.debug("RESPONSE " + response);
}

requestBody = new StringRequestEntity("","text/xml;
charset=UTF-8","UTF-8");
method.setRequestEntity(requestBody);
client.executeMethod(method);
if (method.getStatusCode() == 200){
response = method.getResponseBodyAsString();
LOGGER.debug("RESPONSE " + response);
}
method.releaseConnection();
