- def addContractsRepair(domain: DomainAlias, contractsToAdd: Seq[SerializableContractWithWitnesses], ignoreAlreadyAdded: Boolean)(implicit traceContext: TraceContext): Either[String, Unit]
Participant repair utility for manually adding contracts to a domain in an offline fashion.
Participant repair utility for manually adding contracts to a domain in an offline fashion.
- domain
alias of domain to add contracts to. The domain needs to be configured, but disconnected to prevent race conditions.
- contractsToAdd
contracts to add. Relevant pieces of each contract: create-arguments (LfContractInst), template-id (LfContractInst), contractId, ledgerCreateTime, salt (to be added to SerializableContract), and witnesses, SerializableContract.metadata is only validated, but otherwise ignored as stakeholder and signatories can be recomputed from contracts.
- ignoreAlreadyAdded
whether to ignore and skip over contracts already added/present in the domain. Setting this to true (at least on retries) enables writing idempotent repair scripts.
- def addDomain(config: DomainConnectionConfig)(implicit traceContext: TraceContext): EitherT[Future, SyncServiceError, Unit]
Adds a new domain to the sync service's configuration.
Adds a new domain to the sync service's configuration.
NOTE: Does not automatically connect the sync service to the new domain.
- config
The domain configuration.
- returns
Error or unit.

Participant repair utility for manually moving contracts from a source domain to a target domain in an offline fashion.
- contractIds
ids of contracts to move that reside in the sourceDomain (or for idempotency already in the targetDomain)
- sourceDomain
alias of source domain from which to move contracts
- targetDomain
alias of target domain to which to move contracts

whether to only move contracts that are active in the source domain
