Anyway to start Trafodion without sqstart
Hi there-
Is there a way to start up Trafodion not by using sqstart...? I would like
to be able to start up/stop each node individually.
Thanks!

OK. Then, it'll not be covered in the upcoming admin guide.

I think the concept of a warm start is a carryover from early SeaQuest
days. A warm start was proposed to maintain some monitor and TM states,
but it never was fully implemented.

The purpose I guess is to bypass time-consuming database recovery if it is
a warm start. Say, if you have a clean shutdown of Trafodion, you can warm
restart it. If one use ‘ckillall’, or simply loss power, one needs a cold
start. But I think this is just the concept. May not support yet? We
studied the two gomon scripts, seems identical except some minor difference.
And Narendra is correct, I misunderstand the startup code. It is possible.

The use case is how Apache Ambari works: it assume node-by-node management
of services. This is how you achieve rolling upgrades, stopping all
services on a node, etc.
I wonder if it's possible to first start the monitor (using the startup
command) and then start/stop other components per node. Kind of a hybrid
model.
DCS/REST should already support this use case since it's based on the HBase
model where the scripts start daemons on each configured node.

It is hard to start a single node.
Is there any use case to do so?

Yes. The sqgen command takes in the configuration file for the trafodion
cluster and generates gomon.cold, gomon.warm and other relevant scripts.
These generated scripts are copied to all nodes in the cluster. These
scripts are nothing but the commands to sqshell. sqstart uses either
gomon.cold or gomon.warm to start the Trafodion instance.

DCS and REST follow the HBase model so that should be a simple matter of
invoking the *-daemon.sh scripts.
I think the rest is a matter of using sqshell:

Obviously, you can up/down nodes but I don't know how that works in

Re: 答复: 答复: Anyway to start Trafodion without sqstart
Posted by Amanda Moran <am...@esgyn.com>.
Hi there All-
So this is what is suggested to be able to start Trafodion on each node
individually:
Run sqgen on each node.
Create a new script that would be ran on each node (probably just a
wrapper) that calls gomon.cold.
How will this work for processes that are one per cluster, like the
monitor?
Thanks!

答复: 答复: Anyway to start Trafodion without sqstart
Posted by "Liu, Ming (Ming)" <mi...@esgyn.cn>.
The purpose I guess is to bypass time-consuming database recovery if it is a warm start. Say, if you have a clean shutdown of Trafodion, you can warm restart it. If one use ‘ckillall’, or simply loss power, one needs a cold start. But I think this is just the concept. May not support yet? We studied the two gomon scripts, seems identical except some minor difference.
And Narendra is correct, I misunderstand the startup code. It is possible.

Ming

Subject: Re: 答复: Anyway to start Trafodion without sqstart
The use case is how Apache Ambari works: it assume node-by-node management of services. This is how you achieve rolling upgrades, stopping all services on a node, etc.
I wonder if it's possible to first start the monitor (using the startup command) and then start/stop other components per node. Kind of a hybrid model.
DCS/REST should already support this use case since it's based on the HBase model where the scripts start daemons on each configured node.

Yes. The sqgen command takes in the configuration file for the trafodion cluster and generates gomon.cold, gomon.warm and other relevant scripts. These generated scripts are copied to all nodes in the cluster. These scripts are nothing but the commands to sqshell. sqstart uses either gomon.cold or gomon.warm to start the Trafodion instance.

DCS and REST follow the HBase model so that should be a simple matter of invoking the *-daemon.sh scripts.
I think the rest is a matter of using sqshell:

Obviously, you can up/down nodes but I don't know how that works in relationship to the startup command.

RE: 答复: Anyway to start Trafodion without sqstart
Posted by Narendra Goyal <na...@esgyn.com>.
Yes, one can follow the commands in ‘gomon.cold’ (that sqstart uses (what
Selva mentioned)) to startup without sqstart.
As such, before ‘sqstart’ executes the commands in ‘gomon.cold’, it does
some other checks (like checks for orphan processes), and cleans up IPC
constructs (semaphores, queues, shared memory) via sqipcrm.

Obviously, you can up/down nodes but I don't know how that works in
relationship to the startup command.

Re: 答复: Anyway to start Trafodion without sqstart
Posted by Gunnar Tapper <ta...@gmail.com>.
The use case is how Apache Ambari works: it assume node-by-node management
of services. This is how you achieve rolling upgrades, stopping all
services on a node, etc.
I wonder if it's possible to first start the monitor (using the startup
command) and then start/stop other components per node. Kind of a hybrid
model.
DCS/REST should already support this use case since it's based on the HBase
model where the scripts start daemons on each configured node.

答复: Anyway to start Trafodion without sqstart
Posted by "Liu, Ming (Ming)" <mi...@esgyn.cn>.
From my understanding, it is invalid to start trafodion on node by node mode. Monitor simulate a single image of operating system from a bunch of nodes. One process can be configured to be a pair: active and standby. So when start a trafodion process, it will start two processes on two nodes. It is hard to start a single node.
Is there any use case to do so?
Thanks,
Ming

Yes. The sqgen command takes in the configuration file for the trafodion cluster and generates gomon.cold, gomon.warm and other relevant scripts. These generated scripts are copied to all nodes in the cluster. These scripts are nothing but the commands to sqshell. sqstart uses either gomon.cold or gomon.warm to start the Trafodion instance.

DCS and REST follow the HBase model so that should be a simple matter of invoking the *-daemon.sh scripts.
I think the rest is a matter of using sqshell:

Yes. The sqgen command takes in the configuration file for the trafodion
cluster and generates gomon.cold, gomon.warm and other relevant scripts.
These generated scripts are copied to all nodes in the cluster. These
scripts are nothing but the commands to sqshell. sqstart uses either
gomon.cold or gomon.warm to start the Trafodion instance.
