ATS and RIS File Names

Each ATS and RIS file has a unique name based on the conditions under which it was generated.

The following table provides the naming convention for ATS and RIS files:

type.target.source.threadID.timestamp.sequence.extension

Table 1. ATS and RIS file naming conventions
Name	Description
type	The format of the file: `ats` or `ris`.
target	The name of the database server receiving this replicate transaction.
source	The name of the database server that originated the transaction.
threadID	The identifier of the thread that processed this transaction.
timestamp	The value of the internal time stamp at the time that this ATS or RIS file was generated.
sequence	A unique integer, incremented each time an ATS or RIS file is generated.
extension	The file type. No extension indicates a text file; `xml` indicates an XML file.

The naming convention ensures that all ATS and RIS file names that are generated are unique. However, when an ATS or RIS file is opened for writing, any previous file contents are overwritten. (Enterprise Replication does not append to a spool file; if a name collision does occur with an existing file, the original contents of the file are lost.)

The default delimiter for the timestamp portion of text file names is a colon (:) on UNIX™ and a period (.) on Windows™. You can define the delimiter between the hour, minute, and second values with the CDR_ATSRISNAME_DELIM environment variable. XML files always use a period (.) delimiter between the hour, minute, and second values.

The following is an example of a name of an ATS file in text format on UNIX for a transaction sent by server g_amsterdam to server g_beijing:

ats.g_beijing.g_amsterdam.D_2.000529_23:27:16.6

The following is an example of the same ATS file name in XML format:

ats.g_beijing.g_amsterdam.D_2.000529_23.27.16.6.xml

The following is an example of a similar RIS file name in XML format:

ris.g_beijing.g_amsterdam.D_2.000529_23.27.16.5.xml
