Error in author standby setup

Avatar

Level 4

Hi,

AEM 6.4.

Recently we have planned to add standby author instance in our environment.Currently we are running with one author instance .

We have followed the below document.

How to Run AEM with TarMK Cold Standby

We use NFS shared storage for FileDataStore

Is this an upgraded AEM instance of a new instance?

smacdonald2008 no its just a new instance .We cloned the primary VM and created this new VM and copied the aem installation folder from primary according to the document.

You cannot have a mix of .cfg and .config files. Starting version 6.3 they all must be .config.

As such reaname FileDatastore file extension to .config and use syntax like

path=“/nfs/datastore”

Avatar

Level 4

berliant​ we can try ,but do you think is it causing the error?

Because we are already using this ".cfg" file and syntax configuration in our primary server from long back and its working fine for FileDataStore.

Configuration provided above.

Thanks

You have mix of configuration files .cfg and .config:

org.apache.jackrabbit.oak.segment.standby.store.StandbyStoreService.config

org.apache.jackrabbit.oak.plugins.blob.datastore.FileDataStore.cfg

org.apache.jackrabbit.oak.segment.SegmentNodeStoreService.cfg

That is the issue. In AEM 6.4 they all have to be .config - Configuring node stores and data stores in AEM 6

It should be something like:

org.apache.jackrabbit.oak.segment.standby.store.StandbyStoreService.config

org.apache.sling.installer.configuration.persist=B"false"

mode="standby"

primary.host="10.123.6.15"

port="8023"

interval=I"5"

standby.autoclean=B"true"

org.apache.jackrabbit.oak.segment.SegmentNodeStoreService.config

org.apache.sling.installer.configuration.persist=B"false"

customBlobStore=B"true"

standby=B"true"

org.apache.jackrabbit.oak.plugins.blob.datastore.FileDataStore.config

org.apache.sling.installer.configuration.persist=B"false"

path="/nfsdata/stage_datastore"

The same should be corrected on your primary instance.

Thanks will try.

Please note that when we first time configured node stores and data stores with ".config" following the above doc it did not work then we configured as .cfg.

Let us try now will let you know.

Avatar

Level 4

We made all files ".config" and configure as mentioned in the doc but we started getting datastore exception error in primary aem which was not the case before.

Avatar

Level 4

We fixed the issue and setup primary standby properly now.no more error .

Followed the below document and use the files suggested by Day care

How to setup cold standby instance in AEM
