All,
Here is a description of the dependencies amongst the OpenSAF Services
which I think is useful for developers and users of the project. Note
some of these dependencies are bi-directional. (I am sure somebody can
turn this list into an exciting graph).
1. AvSv or the Availability Service which consists of SAF AMF + SAF CLM
+ OpenSAF Availability Manager depends on:
- LEAP (OS Abstraction Layer )
- Message Distribution Service or MDS
- Distributed Tracing Service or DTSv
- System Resource Monitoring Service or SRMSv
- Event Distribution Service or EDSv
- HPI Integration Service or HISv
- Management Access Service or MASv
- Persistence Store Service or PSSv
- Message Based Checkpointing Service or MBCSv
2. CPSv or the SAF Checkpoint Service depends on:
- LEAP
- MDS
- DTSv
- AvSv (Specifically AMF & CLM)
- MBCSv
- MASv
3. EDSv or the SAF Event Distribution Service depends on:
- LEAP
- MDS
- DTSv
- AvSv (AMF)
- MBCSv
- MASv
4. GLSv or the SAF Lock Service depends on:
- LEAP
- MDS
- DTSv
- AvSv
- MBCSv (for director redundancy)
- the SAF Checkpoint Service or the CPSv (for node-director
redundancy)
5. MQSv or the SAF Message Service depends on:
- LEAP
- MDS
- DTSv
- AvSv (Specifically AMF & CLM)
- MBCSv
- MASv
6. HISv or Hardware Integration Service depends on:
- LEAP
- MDS
- DTSv
- EDSv
- HPI (but this is a pre-requisite as far as OpenSAF is
concerned)
7. Message Based Checkpointing Service or MBCSv
- LEAP
- MDS
- DTSv
8. Interface Service or IFSv depends on:
- LEAP
- MDS
- DTSv
- AvSv
- MBCSv (for director redundancy)
- the SAF Checkpoint Service or the CPSv (for node-director
redundancy)
- MASv
9. Management Access Service or MASv depends on:
- LEAP
- MDS
- DTSv
- AvSv
- MBCSv
10. Persistent Store Service or PSSv depends on:
- LEAP
- MDS
- DTSv
11. System Resource Monitoring Service or SRMSv depends on:
- LEAP
- MDS
- DTSv
- AvSv
12. Distributed Trace Service or DTSv depends on:
- LEAP
- MDS
- DTSv
- AvSv
- MBCSv
- MASv
13. Message Distribution Service depends on:
- LEAP
- Transport Layer, which today is TIPC.
Thanks
