What caches uses Alfresco and how to properly clean them?

After several experiments with business processes, I noticed that the old definitions of business processes somewhere is cached.

 

For example, I developed some business process, then installed the AMP file with it. I worked with it, and then decided to make some changes.

 

For this, I again assembled the AMP file and installed it:

 

[bykovan@docflow alfresco-community]$ sudo java -jar bin/alfresco-mmt.jar uninstall some-module-repo tomcat/webapps/alfresco.war
...
[bykovan@docflow alfresco-community]$ sudo java -jar bin/alfresco-mmt.jar install amps/some-module-repo-1.0-SNAPSHOT.amp tomcat/webapps/alfresco.war
...


But I don't see my changes after deploy! To make the change take effect I have to make quite a lot of extra work.

 

(Thanks to Mr. Potts for sequence of actions)

 

1 Shutdown Tomcat

 

[bykovan@docflow alfresco-community]$ sudo ./alfresco.sh stop

 

2 Re-create the alfresco database

 

[bykovan@docflow alfresco-community]$ sudo -i -u postgres
[postgres@docflow ~]$ psqlpsql
(9.5.5)
postgres=#
postgres=# drop database alfresco;
...
postgres=# create database alfresco;
...
postgres=# alter database alfresco owner to alfresco;
...
postgres=# \q
[postgres@docflow ~]$ exit

 

3 Remove everything from alf_data

 

[bykovan@docflow alf_data]$ sudo rm -r *

 

4 Remove alfresco and share folders

 

[bykovan@docflow alfresco-community]$ sudo rm -r alfresco
[bykovan@docflow alfresco-community]$ sudo rm -r share

 

5 Start Tomcat

 

[bykovan@docflow alfresco-community]$ sudo ./alfresco.sh start

 

6 Wait until the database is initialized...

 

7 Set the administrator's password

 

SELECT     
   anp1.node_id, // paste to the update statement   
   anp1.qname_id, // paste to the update statement   
   anp1.string_value FROM alf_node_properties anp1    

INNER JOIN alf_qname aq1 ON aq1.id = anp1.qname_id    
INNER JOIN alf_node_properties anp2 ON anp2.node_id = anp1.node_id    
INNER JOIN alf_qname aq2 ON aq2.id = anp2.qname_id

WHERE
   aq1.local_name = 'password'     
   AND aq2.local_name  = 'username'    
   AND anp2.string_value = 'admin';

UPDATE    
   alf_node_properties
SET    
   string_value='209c6174da490caeb422f3fa5a7ae634'
WHERE node_id=... and qname_id=...;

 

 

(where '209c6174da490caeb422f3fa5a7ae634' is NTLM-encoded string 'admin')

 

8 Restart Tomcat

 

9 Log-in as Admin with password admin, add users etc...

 

What caches uses Alfresco and how to properly clean them?

 

I use the following configuration:

 

  

Alfresco Share v5.2.d (r134641-b15, 
Aikau 1.0.101.3, Spring Surf 5.2.d,
Spring WebScripts 6.13,
Freemarker 2.3.20-alfresco-patched,
Rhino 1.7R4-alfresco-patched,
Yui 2.9.0-alfresco-20141223)

Alfresco Community v5.2.0 (r134428-b13) schema 10005

 

Do I understand correctly? If I need to undeploy / remove the "old" definitions of business processes, all I need is the workflow admin console?.. Should I delete anything from the database or from the file system directly?..

 

I would be very grateful for the information. Thanks to all.
