using variables in data-config.xml

[Prasanna S. Dhakephalkar]

Hi,

 

I have 7 cores.

 

In each data-config.xml , I have

 

<dataSource name="ds1" type="JdbcDataSource"

                driver="com.mysql.jdbc.Driver"

                url="jdbc:mysql://localhost:3306/abcd"

                user="userName"

                password="passWord"

/>

 

There is similar structures on production, testing and partner instances.

So if I have to make changes I have to do in all data-config files.

 

I am looking for a mechanism where some variables 

Like 

dbname=abcd

dbusre=username

dbpass=password

are defined in solr.xml file under

../server/solr_test directory

 

and can be referenced
.../servre/solr_test/{core_1,core_2,...core_7}/conf/data-config.xml

 

Tired looking on net, I found articles that are telling me to edit
solrconfig.xml in each core, that does not satisfy my need.

 

I am using solr 5.3.1

 

Regards,

 

Prasanna.
