Troubleshooting
Problem
When you use the asnodename option to back up a client, you might need to adjust the value of the TXNGROUPMAX parameter for the target node.
Symptom
In this scenario, a Netezza backup was done from Spectrum Protect client NODE1 and the following option was used :
asnodename MYNODE
The backup failed with the following error :
ANS0246E (RC2070) Issue dsmEndTxn and then begin a new transaction session.
Diagnosing The Problem
In this example, the following proxy relationship is configured :
Target Node Agent Nodes
----------------------- -----------------------------
MYNODE NODE1
On the Tivoli Storage Manager server, use the QUERY NODE command to verify the value of the TXNGROUPMAX parameter for the nodes. For example :
q node mynode f=d
Node Name: MYNODE
...
Transaction Group Max: 256
...
q node node1 f=d
Node Name: NODE1
...
Transaction Group Max: 4000
...
In this example, because the backup is done with NODE1 using the ASNODENAME MYNODE option, the TXNGROUPMAX value used is 256.
Resolving The Problem
When a backup is done using a proxy node, it is the TXNGROUPMAX value of the target node that is used for the backup. If the ANS0246E error is received, you must update the TXNGROUPMAX value of the target node. For example :
update node MYNODE txngroupmax=1000
