7.5. More Slony-I Help

If you are having problems with Slony-I, you have several options for help:

7.5.1. Slony-I Website - the official "home" of Slony-I contains links to the documentation, mailing lists and source code.

7.5.2. Mailing Lists

The answer to your problem may exist in the Slony1-general mailing list archives, or you may choose to ask your question on the Slony1-general mailing list. The mailing list archives, and instructions for joining the list may be found here. .

If you are a question to the mailing list then you should try to include the following information:

  • The version of Slony-I you are using

  • The version of PostgreSQL you are using

  • A description of your replication cluster. This should include the number of replication sets, which node is the master for each set.

  • The text of any error messages you are receiving from slony

  • If you received the error while running a slonik script then try to include the script

It is a good idea to run the Section 5.1.1 tool before posting a question to the mailing list. It may give some clues as to what is wrong, and the results are likely to be of some assistance in analyzing the problem.

7.5.3. Other Sources

  • There are several articles here Varlena GeneralBits that may be helpful but was written for an older version of Slony-I.

  • IRC - There are usually some people on #slony on who may be able to answer some of your questions. Many people leave themselves logged into IRC and only periodically check the channel. It might take a while before someone answers your questions

  • pgpool

    pgpool is a connection pool server for PostgreSQL; it allows an application to connect to it as if it were a standard PostgreSQL server. It caches connections, which reduces the overhead involved in establishing them. It supports a "scheduled switchover" feature, which would allow dynamically switching over from one server to another. That would be very useful when doing a SLONIK MOVE SET, as it would allow applications to be switched to point to the new origin without needing to update their configuration.
