Unable to launch primay AEM instance in primary run mode for cold standby environment.

[JosephKwon]

Hi,

I'm currently working on installing author instance with cold standby instance.

At first, I have installed primary AEM 6.3 instance as per document [0] below.

The AEM instance just installed, has been configured with datastore(filestore) storage.

Next, I restarted the primary AEM instance with primary run mode with below three PID config files.

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

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

path="/home/joseph/SHARED_DATASTORE"

minRecordLength=I"1024"

maxCachedBinarySize=I"1048576"

cacheSizeInMB=I"1024"

cacheSize=L"68719476736"

cachePath="./crx-quickstart/repository/cache"

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

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

repository.home="./crx-quickstart/repository"

customBlobStore=B"true"

standby=B"false"

tarmk.size=I"256"

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

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

mode="primary"

port=I"8023"

However, right after start the primary instance with primary run mode, it won't properly get started.

I see many of errors tells that missing repository service.

Please see error message below [1]

I'm not able to see AEM web UI due to the error.

I'm not sure if I did something wrong.

Please advise. Any comment or advice will be welcome.

Thanks!!

Jörg Hoh​ Can you help here?

Thanks kautukshni,

I've succeed on Windows 7 with above conf.(just slightly changed path scheme for Windows) files but failed on CentOS(or Redhat Linux).

I believe this should work on Linux as well.

Thanks,

Joseph

This is for information only.

The configuration files for scratch installation -> http://125.128.34.143:10080/install.initial.tar

The configuration files for initail primary run mode start -> http://125.128.34.143:10080/install.pri.fail.tar

Thanks

Here is a community article on this subject that may help -- http://www.aemcq5tutorials.com/tutorials/tarmk-cold-standby-aem-6/

Thanks, smacdonald.

However I should use shared datastore for cold standby in order to minimize disk space usage for sync operation.

So I can't use default segmentstore for data storage but need to use datastore(filestore).

The article which you commented does not cover datastore storage.

Thanks anyway,

Joseph

Hi JosephKwon,

With above configurations which you have provided,I have tested in my local Cent OS Linux.

Primary author is working as expected with a shared datastore.

If you are still facing the issue,Once again try a new setup.

Thanks,

Hi Techaspect Solutions,

As you commented, I've tried again then succeeded.

I'm not sure what was wrong in my testing environment.

I sincerely appreciate your great effort in supporting me.

Great thanks.

Joseph
