Endeca 11.2 Preview : Missing deployment settings
Behaviour :-
Following Exception/Error comes in Endeca tools and framework IFCR log during preview page in 11.2 Endeca Experience manager using preview functionality.
Root Cause:-
The root cause of missing deployment setting is Endeca site content migration from older version of Endeca to 11.2. Migrate site utility does not generate deploymentSettings and reportSettings folder under /configuration/tools folder of exported zip file.
Solution :-
Follow the following steps to resolve this
1. Export the tools using <<Endeca_APp>>/control/runcommand.sh IFCR exportApplication tool
2. create deploymentSettings folder under /configuration/tools folder
3. Create a file _.json file and put the following content
{
"ecr:type": "deployment-settings",
"authoringApplicationExportDirectory": "/opt/app/endeca/ToolsAndFrameworks/11.2.0/deployment_template/lib/../../server/workspace/state/generation_data"
}
4. import the tools once again.

Endeca 11.x : There was a problem with the zip file given
Behaviour :-
Following Exception/Error comes during baseline or promoting content from Experience Manager. Error shows that "there was a problem with Zip File given". This exception leads to show blank page in production site
Solution :-
No New Content was added by business during promote content and zip file was correct. OOTB endeca creates a temporary files under /tmp folder before applying content to MDEX engine and tmp folder was out of space so zero bytes contents was getting applied to MDEX. Free some /temp space and promote content.

Endeca 11.x : Property 'priority' must be a positive integer
Behaviour :-
Following Exception/Error comes during Endeca experience manager content migration between environments or importing contents from zip file.
Solution :-
Sometimes business user assigns rules priority less than 1 and Endeca XM accepts that value while saving the rule. Above Exception comes if any rule priority is less than 1. Ask business user not to assign rules priority as 0 or any value negative number. Extract the zip file and change the priority in respective JSON file as per error to any positive integer and try importing again.

ATG-Endeca Integration : How to Enable/Disable automatic indexing after BCC Post Deployment?
Endeca Indexing jobs getting triggered automatically just after BCC post deployment. IndexingDeploymentListners helps trigger indexing and part of /atg/epub/DeploymentServer component.
Enable Automatic Indexing
Add IndexingDeploymentListner component to the list of listeners on /atg/epub/DeploymentServer Component. Bydefault, IndexingDeploymentListner is included.
Disable Automatic Indexing
Remove IndexingDeploymentListner component to the list of listeners on /atg/epub/DeploymentServer Component.

Can Endeca Partial Indexing be performed after inventory or direct SQL update?
Behaviour
As per default behavior of ATG Endeca integration, Endeca Partial indexing does not update index with inventory update. ATG driven partial index looks for IncrementalItemQueueRepository and this repository does not get updated during direct SQL update or inventory update.
Solution
Endeca Partial Indexing triggered from ATG layer look for srch_update_queue table to fetch the product/sku id to apply for partial update.
Write a job/code to insert the sku/product id to srch_update_queue table with proper status so partial process can pick it up. Invalidate the IncrementalItemQueueRepository cache and run the partial indexing from dyn/admin. This will identify the updated data and update back to Endeca MDEX engine.

Oracle Endeca ITL and Expereince Manager High Availability Architecture
What are High Availability and Failover
- High availability as the ability for the system to continue functioning after the failure of one or more of the servers.
- Failover as one possible implementation of high availability. Failover is defined as the ability for client connections to migrate from one server to another in the event of server failure so client applications can continue to operate.
How to Setup ITL and XM Failover
Two Information Transformation Layer (ITL) servers which host Tools and Framework required achieving high availability and another for Disaster recovery (DR) if required.
Only one ITL can be in active mode and remaining failover/backup should be passive mode . As per architecture, specific, in the diagram below, folders should be shared between primary and backup ITL servers using shared drive. DR generally hosted in the different data center so file system replication or other technique required for DR environment. The Shared drive can be setup during product and app installation.
Following points needs to be taken care of during installation
- Installation path should be same in all environments to avoid any conflicts and issues.
- Endeca Application Initialize services script required to run from all the ITL servers for the first time.
- Make sure to copy same Dgraph cluster XML with same naming convention to avoid duplicate Dgraph instance
Find out block diagram below for HA understanding and setup
What needs to be shared between active and passive ITL servers:-
- Tools and Framework state folder
- Endeca application Data folder
- CAS workspace shared folder
What happens if failover happens during mid-process
- Failover ITL would have to begin the process again if primary ITL Dgidx failed from Dgidx process.
- Failover ITL would have to begin the entire process again if primary ITL forge failed.
- Failover ITL would have to begin the entire process again if primary CAS indexing failed.
Note : ATG properties need to be changed to redirect indexing to failover ITL in the event of primary ITL fault, but best practice would probably be to restart the indexing process again.
