Hello,

I have tried to subscribe to general forums but i wasn't able to, hence i
would appreciate if we can keep this thread and have the replies over email=
.

I want to have more background about the dependencies of solr/zookeeper
services and the task schedulers -ful/incremental indexing.

So in case of a manual restart or unplanned reboot our services are set to
start manually hence i wanted to setup the dependency between them so I
wanted to confirm  if the order is the following one:
1.First Zookeeper service
2.Solr service

If there is any documentation on this matter please let me know.

Another similar topic is the following one:
Yesterday we encountered a dirty reboot and right after the incremental
indexing task was failing with :
" Job Id: 172605, Status: Failed

Indexing failed. Refer incremental-indexing.log for more information.

java.lang.Exception: File ./index.properties does not exist to read the
property "last_index_time""


The file was there but was empty without any timestamp

So i did the following:


Do the following:

1.open it check if is empty or not and take a backup of it

2.disable the task, take the content of that file from stage

3.check in the database the last successful one --timestamp

4.updat that file with the above timestamp

5.probably it wont work

6.if doesn t work update the timestamp with the current date and run the
job,, once got successfully completed end it disable it and update the
timestamp with the value from 2nd step

5

update [X].[dbo].[C_CACHE_SEARCH_INDEX_JOB_AUDIT]

set Status =3D 'Failed'

where Status =3D'In Progress'



6.enable the task and run it and also monitor it will complete successfully


So my question is when this scenario can happen and also is there any
procedure to stop/start the components in a controlled way?


Any maintenance procedure will be highly appreciated.


Many thanks in advance,

Ana
