What caches uses Alfresco and how to properly clean them? - alfresco

Question

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.
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 ~]$ psql
psql (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...

Answer 1

You can find temp files at this location
<<alfresco-community>>\tomcat\temp
and files are stored in alf_data
<<alfresco-community>>\alf_data

Answer 2

Axel Faust gave an exhaustive answer:
What caches uses Alfresco and how to properly clean them?
"Any caches that Alfresco uses are emptied / cleared when Alfresco is restarted... Generally you should NEVER have to work with the database directly. It is strongly discouraged and not supported by Alfresco in any way."
It solved my issue.
