Hi Shaheed,
I found this piece of code (in CartridgeMgtBehaviour.java) which seems to
define it, to summarize, the clusterId is a composed of:
subscription alias + "." + cartridgeType + ".domain".
It also truncates the clusterId to 30 characters (as observed)
protected String generateClusterId (String alias, String cartridgeType) {
String clusterId = alias + "." + cartridgeType + ".domain";
// limit the cartridge alias to 30 characters in length
if (clusterId.length() > 30) {
clusterId =
CartridgeSubscriptionUtils.limitLengthOfString(clusterId, 30);
}
return clusterId;
}
Thanks
Martin

Can somebody simply state the relationship between the subscription alias and
the cluster id, i.e. how does the latter *exactly* get generated from the
former? For example is it:
trunc(alias + "." + alias + some domain thingy, 30)
What is the correct formula?

Thank you Reka for getting back to me on this. For the cluster ID limitation
of 30 characters max, is it configurable? Where in the code do we define this
limit? I have same question for the node name.
Currently the length for cluster id is not configurable. This is hard coded to
30 characters. This is intentionally done since too long cluster ids can be
problematic (when creating DB tables, etc.).

Hi Jeffrey,
I'm not sure whether stratos enforces any character limit for the cartridge
alias. If it is not explicitly handled, then we can use the character limit as
the DB support. The clusterId which is generated by stratos, is taken 30 as the
maximum length and the node name in jclouds, is taken 3-15 characters as i
could find it from the code segment in stratos.
Thanks,
Reka

Hi,
It seems Stratos currently enforces a limit on how long the alias for a
cartridge can be. Can someone confirm if there is a limit and if so what is
the max length? Where is this configured in the Stratos code? We've seen
the case where two cartridges use the same large prefix for alias. They both
got subscribed successfully but the instances failed to launch.
Thanks,
-Jeffrey
