This procedure allows you to re-index from scratch without causing downtime. The Front End uses existing indexes for search retrieval, and hotswapping replaces the old indexes with new ones.

To re-index the database without deleting the current indexes in memory:

Log on to the FE server and enter the following commands to view the search_schema.xml file:

se_conf

vi search_schema.xml
Search for the <agent> tag to get the path to the <indexes> directory.

In the following example, /exlibris/primo/p4_1/ng/jaguar/home/profile/indexes is the path of the indexes directory:

<agents desc="collections of all search instances to be searched by jaguar" auto_deploy="active" swapping_type="slices">

<agent port="9501" connection_type="local" host="primo1.corp.exlibrisgroup.com" active="true">
<slices slice_count="1" name="main" active="true">
<slice>
<path>/exlibris/primo/p4_1/ng/jaguar/home/profile/indexes/inst_1_index</path>

<load2ram>true</load2ram>
</slice>
</slices>
</agent>

</agents>
On each SE server, move to the directory that contains the indexes directory and enter the following command to back it up, where <date> is the current date:

cp -Rp indexes indexes.<date>
Log on to the BE server as the primo user.
Enter the following commands to delete the index files:

be_bin

./clean_indexes.sh
From a Web browser, enter the URL for the Back Office server. For example:

http://primo.exlibris.com:1601/primo_publishing/admin/acegilogin.jsp
From the Back Office home page, click Primo Home > Monitor Primo Status > Process Monitoring.
To re-index the database, click Execute for the Indexing_and_Didumean_and_Hotswapping process.
Log on to the FE server as the primo user.
Enter the following commands to monitor the job execution on the FE:

fe_log

tail -f jaguar_server.log

Do not restart the FE and SE servers so that you will be able to keep searching with the existing indexes.
