Thread: Command prompt replication.
Hi,
I'm evaluating command prompts replication server and have an issue I need help to resolve.
I have install the master and slave from the postgres code supplied from command prompt. Have created a benchpg database which is automatically created by the contrib program, pg_bench. Then proceeded to copy that database to the slave via pg_dump, etc...
Im currently running both databases on separate servers. And I have started up :
/usr/local/pgsql/bin/mcp_server -c /usr/local/pgsql/etc/mcp_server.conf -l /var/log/mcp_server.log &
Based on the output both pg servers connect to the mcp server successfully..
Ok..
Not testing the replication by inserting a record into the master database table branches.
As soon as I enter this record /var/log/mcp_server.log is populated with :
DEBUG_MSG: MCP-M-Recv| recno: 16003065 txnid: 85 datalen: 25 flags: TABLE_BEGIN TABLE_LIST TABLE_END

DEBUG_SLAVE: 0: Recv ACK from Slave(0) => Slave(0).vrecno = 16003071
On the slave server the /var/log/postgresql.log is polutated with this:
LOG: INCSKIP to 16003071
LOG: SET mcp_ack_recno: 16003071
Based on my limited knowledge and little documentation provided by command prompt, all looks well??? However the record I added to the master has not been copied to the slave.
Regards,
Theo

Could you please post a request to support@commandprompt.com with the following information: 1. master postgresql.conf replication configuration, we don't need the whole postgresql.conf 2. slave postgresql.conf replication configuration, we don't need the whole postgresql.conf 3. The schema of the table you are inserting into 4. The schema of the table that is supposed to be recieving the updates. Thanks. Joshua D.
