#1574 CKPT: Support DNs longer than 255 bytes

[Pham Hoang Nhat]

Ticket [#191] introduced generic support in OpenSAF for DNs longer than 255 bytes. Each individual OpenSAF service will also have to be adapted to support long DNs. CKPT should have this feature. The applications may want to use long DNs for checkpoint name.

[Pham Hoang Nhat]

The attachment is the implementation proposal for the enhancement.

[Mathi Naickan]

Except in AMF (and thereafter in LOG, NTF and SMF), i don't see support for this as a high priority for OpenSAF.
In other words, it doesn't become an obvious thing to specify a really long DN name for a checkpoint! Ofcourse one can imagine of it, but still.

[A V Mahesh (AVM)]

Following are some requirements :

To alignment across the middleware instead of different places where it is allowed or not to use the extended type, and to have meaningful name convention for CKPT name, that can request longer names than 255.

[A V Mahesh (AVM)]

Do Consider the LONG DN requirement for Replica as well

Object Class : Table 2 DN Formats for Objects of Checkpoint Service Classes (SAI-AIS-CKPT-B.02.02 spec)

1) SaCkptCheckpoint -- "safCkpt=...,* "

2) SaCkptReplica -- "safReplica=...,safCkpt=...,* "

example IMM Objects :

CKPsafCkpt=DemoCkpt,safApp=safCkptService
safReplica=safNode=SC-1\,safCluster=myClmCluster,safCkpt=DemoCkpt,safApp=safCkptService
