Your Answer
The following sections contain information about mysqld options and server variables that are used in replication and for controlling the binary log. Options and variables for use on sources and replicas are covered separately, as are options and variables relating to binary logging and global transaction identifiers GTIDs. A set of quick-reference tables providing basic information about these options and variables is also included.
This variable specifies the server ID. For additional information, see Section If replicate binary option server ID is set to 0, binary logging takes place, but a source with a server ID of 0 refuses any connections from replicas, and a replica with a server ID of 0 refuses to connect to a source.
Note that although you can change the server ID dynamically to a nonzero value, doing replicate binary option does not enable replication to start immediately. You must change the server ID and then restart the server to initialize the replica, replicate binary option.
For more information, see Section cnf is not found, generate a new UUID and save it to this file, creating the file if necessary. The auto. cnf file has a format similar to that used for my. cnf or my. ini files, replicate binary option. cnf file is automatically generated; do not attempt to write or modify this file. When using MySQL replication, sources and replicas know each other's UUIDs. The value of a replica's UUID can be seen in the output of SHOW REPLICAS or before MySQL 8.
Once START REPLICA has been executed, the value of the source's UUID is available on the replica in the output of SHOW REPLICA STATUS. As of 8. Issuing a STOP REPLICA or RESET REPLICA statement does not reset the source's UUID as used on the replica. In addition, the replication receiver thread generates a warning if either of the following is true:.

Connect and share knowledge within a single location that is structured and easy to search. A digital call option cash-or-nothing can be replicated with two call options with different Strike. When we make the delta infinitely small and assume we have arbitrary strike prices.
We get:. Going back to the original question, there is no static replication. This is clear from the first answer above which states that a call spread with an infitesimal difference between their strikes is needed. To arrive at an approximate replication, we need the probability of the underlying fixing in the USD 5 interval between the calls to be small, hence:.
Going towards the strike at limited volatlity and time to expiry, the delta of the binary rises above that of the replica. Adjusting the positions in the options of the replica would probably not liquidity-wise be feasible - hence the second answer:.

Reasoning: a binary option's payout graph has an infinite slope at the strike price, whereas all vanilla options and underlyings have finite-slope graphs. I don't think you can add finite-slope combinations to get infinite slope, unless you use an infinite number of them. Add a comment.
