# Restarting services in OCC
### **What is the proper order of restarting services in OCC**
#### Detailed Guide to Stop inConcert
1. Safely stop all components of inConcert:
```
/usr/share/inconcert/services/stop.sh
```
2. Stop additional components used by inConcert:
```
sv stop /etc/service/*
```
3. Stop the Cassandra Database Engine:

```
4. Validate that all inConcert services are stopped
```
sv status /etc/service/*You can validate Cassandra's state with:/etc/init.d/cassandra status
```

### Step-by-step guide to starting inConcert
1. Start the Cassandra Database Engine:
/etc/init.d/cassandra start
It's a good idea to wait a couple of minutes before proceeding, so that the database engine starts completely before the inConcert services start.
It can be executed:
```
nodetool statusAnd from the log confirm that it is ready to receive connectionstail -F /var/log/cassandra/system.log and search for the message "Listening for thrift clients"
```
Until you get:
```
xss = -ea -javaagent:/usr/share/cassandra/lib/jamm-0.2.5.jar -XX:+UseThreadPriorities -XX:ThreadPriorityPolicy=42 -Xms1024M -Xmx1024M -Xmn100M -XX:+HeapDumpOnOutOfMemoryError -Xss180kDatacenter: datacenter1=======================Status=Up/Down|/ State=Normal/Leaving/Joining/Moving-- Address Load Tokens Owns (effective) Host ID RackUN 10.2.14.4 102.85 MB 256 100.0% ccaf188d-bb9b-41c4-ac6c-3af479df3b29 rack1
```
2. Start additional components used by inConcert:
```
sv start redis* Clean the RealTimeKeys.redis-cli -p 6377 KEYS "RealTime::*" | sed 's/.*/"&"/' | xargs redis-cli -p 6377 DELwhen there is authentication in redis: 'xxx' is the authentication passwordredis-cli -p 6377 -a 'xxx' --no-auth-warning KEYS "RealTime::*" | sed 's/.*/"&"/' | xargs redis-cli -p 6377 -a 'xxx' --no-auth-warning DEL* Clean configuration_serverredis-cli -p 6377 KEYS "CONFIGURATION_SERVER::SESSIONS_TIMESTAMP" | sed 's/.*/"&"/' | xargs redis-cli -p 6377 DELwhen there is authentication in redis: 'xxx' is the authentication passwordredis-cli -p 6377 -a 'xxx' --no-auth-warning KEYS "CONFIGURATION_SERVER::SESSIONS_TIMESTAMP" | sed 's/.*/"&"/' | xargs redis-cli -p 6377 -a 'xxx' --no-auth-warning DELsv start redis-agentservicesv start redis-outboundenginesv start webdesignersv start configserversv start elasticsearchsv start allegroproxy* redis-outboundengine only if it is build 2610 or higher* elasticsearch only on the first node/usr/share/inconcert/services/start.sh
```
3. Start inConcert Services:
```
Finally, upload the nginx service since everything else is upsv start nginx
```

### **In case of restarting only the Asterisk service, it must be taken into account that if this is done in production (with connected agents) it is very likely that Fail2Ban will generate a ban on the IP of the agents.**
**To avoid this situation, restart the service following these steps:**
1. Shut down the Fail2Ban service:
```
service fail2ban stop
```
2. Shut down the Asterisk service:
```
sv stop asterisk
```
3. Start up the Asterisk service:
```
sv start asterisk
```
4. Wait 10-15 seconds.
Start up the Fail2Ban service:
```
service fail2ban start
```
