Sayan,
Some corrections regarding dependency of GLSv
1) GLSv does not depend on CPSv for check pointing it uses flat shared
memory directly(Earlier GLSv used to use CPSv, but
later on we removed the dependency on CPSv)
2) GLSv also depends on MASv
The correct dependency is as follows
GLSv or the SAF Lock Service depends on:
- LEAP
- MDS
- DTSv
- AvSv
- MBCSv (for director redundancy)
- MASv
Thanks,
Ravi

Subject: [Users] Dependency data for OpenSAF Services
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
Sayan
