Err "oversized data" on sendTX with 24.4.1

[saravadeanil]

Description

Hi, I am using quorum node with version 24.4.1. I am facing "oversized data" error while sending tx of size above ^64KB.

Initially, I setup the node with genesis.json where as gasLimit=0x47b760 and txnSizeLimit=64.

But I am facing "oversized data" error while performing send tx of size above ^64KB. Hence I updated the gensis.json file gasLimit= 0x218711a00 and txnSizeLimit=128.

After changing the genesis.json file I get below error on my node.

quorum-node Fatal: Failed to write genesis block: database contains incompatible genesis (have 04a4adddb15c6ddd6b6355aba675822a575919e6ed4f537ea85b506c8061f1a9, new 6c6be2ce827e28b89bb65ed2360e00839e9de6ee48041153f792d4df38eb5e30)

However, when I start the node from scratch it pickups new configuration.

Questions?

1. Can I update the gasLimit= 0x218711a00 and txnSizeLimit=128 on my exisiting node or I need to reset the node from scratch?
2. Can I change the genesis block 04a4adddb15c6ddd6b6355aba675822a575919e6ed4f537ea85b506c8061f1a9 to 6c6be2ce827e28b89bb65ed2360e00839e9de6ee48041153f792d4df38eb5e30?

I also tried this but still it is not changing the transactionSizeLimit for me.

Genesis config will only work for the genesis block. To change the transaction size and gas limit for an existing chain, you will need to configure the Transitions config and set the limit for a future block.

See usage here:

@frank-lim-partior Actually, I am using clique protocol node. Does it supports the transitions block?

I tried adding it but it doesn't reflect the changes on the nodes.
