Per-process setting

Usually, variables are set globally, for all processes. This is done by specifying no process name, or *.

SET LOG_FILE=/home/oracle/log/%N.%E
SET *.APPLY.INSTANTIATE_SCN NOW


If the variable value needs to be set differently for a process, use SET with a process name, e.g.

SET APPLY.LOG_FILE=/home/oracle/log/%N.%E
SET APPLY.INSTANTIATE_SCN NOW


If the variable needs to be set back to the global "*" setting, use RESET command.

LOG_FILE_SIZENote that if both global "*" and per-process values of the given variable are set then the per-process value has higher priority, e.g.

   *.MAILCFG_FROM = john@dbvisit.com
MINE.MAILCFG_FROM = george@dbvisit.com

With this settings MINE process uses email george@dbvisit.com while APPLY and FETCHER processes use john@dbvisit.com.


Variables can also be set with MEMORY_SET, which only sets it in memory and not the DDC file. After a restart of the process the setting will no longer take affect (unless MEMORY_SET is specified in the DDC file).

To clarify:
The MEMORY_SET command sets the value locally, for that one process only and is NOT written to the DDC file.  The value is lost upon restart.
The SET command  sets the value locally, AND writes into the repository in the database so it will not be lose when the process is restarted.

Variable reference


Internal VariableDescription
APPLY_CASE_CONVERT

When a table is prepared, should the name from MINE be kept as-is, made uppercase, or lowercase? This is honored for case-sensitive databases only (MySQL and MSSQL).
Default is UPPER. 

Parameter change needs a process restart: No

APPLY_COLUMN_NAMES_MAP

Allows global rename of columns. Translates column names on source database to new column names on target database. This is handy if replicating from one database to another type of database (eg MySQL) where a specific column cannot be used because it is a reserved word.

Example: set APPLY_COLUMN_NAMES_MAP PRIMARY=PRIMARY_VALUE

This will rename the column PRIMARY to PRIMARY_VALUE on the target database. 

Multiple columns pairs can be separated with commas: 

set APPLY_COLUMN_NAMES_MAP PRIMARY=PRIMARY_VALUE, ALTER=ALT

Default is an empty string.

Parameter change needs a process restart: APPLY

APPLY_DATABASE

Connection definition for the APPLY database. This is TNS connection string for Oracle, connection string for MySQL or DSN (Data Source Name) for MS SQL.

Should not be changed once replication is configured.

APPLY_DATABASE_DBID

DBID (see v$database) of databases where apply connects. The default is empty and the variable is optional; however, it's always set by setup wizard. This helps to check that the connection strings resolve to correct databases as the apply server.

Default: (empty)

Should not be changed once replication is configured.

APPLY_DATE_FORMAT
The output format for dates, timestamps and intervals when using flatfiles. YMD is human-readable like YYYY.MM.DD (+time portion, time zones) or Oracle-like for intervals (+3-2 for year-day). ISO8601 is Java-like 2014-12-05T12:34:56 or P12Y2M.
  • AUTO (default) (Auto is YMD for CSV)
  • YMD
    • ISO8601 (for Avro)

Parameter change needs a process restart: APPLY

APPLY_DBI_ARRAY_BIND
  • NO
  • YES (default)

LOAD feature uses array binding if this variable is set to YES.

Parameter change needs a process restart: No

APPLY_DBI_ARRAY_BIND_ROWS

The size of Array Bind when it is switched on for LOAD feature.

Default: 500

Parameter change needs a process restart: No

APPLY_DBI_CACHE_STATEMENTS
  • NO
  • YES (default)

Parameter change needs a process restart: No

APPLY_DBI_PIPELINE

The number of rows sent to parallel threads at once, to minimize Perl thread copy overhead when using LOAD feature.

Default: 25

Parameter change needs a process restart: No

APPLY_FILEOUT_FILE_BATCH_SIZE

This parameter governs the total size of intermediary files in the APPLY_FILEOUT_STAGING_DIR BEFORE they are flushed to final CSV output, and delivered to APPLY_FILEOUT_TARGET_DIR. This work is done in batches, rather than writing new CSV files for each operation which would be inefficient, and can be tuned according to your requirements.

If only a single table is replicated then this value would correlate closely to the file size for the actual output file. The file will be closed then this size is reached and the transaction is completed.

Values: integer

Default: 10485760 (10mb)

Parameter change needs a process restart: APPLY

APPLY_FILEOUT_FILE_CSV_COMMA

The field separator for CSV output files.

Default: (empty)

Value: string, with support for escaped chars:

\0 \a \b \t \n \v \f \r \x00 (arbitrary hex number ) \\ (backslash)

Parameter change needs a process restart: APPLY

APPLY_FILEOUT_FILE_CSV_NEWLINE

The row separator for CSV output files.

Default: (empty)

Value: string, with support for escaped chars:

Parameter change needs a process restart: APPLY

APPLY_FILEOUT_FILE_FORMAT

The file type for the output file.

  • OFF (default)
  • NONE (OFF)
  • CSV

Parameter change needs a process restart: APPLY

 

APPLY_FILEOUT_FILESYSTEM

The type of filesystem to be written to.

  • FS (Filesystem) (default)
  • HDFS (Hadoop)

Parameter change needs a process restart: APPLY

APPLY_FILEOUT_HDFS_NAMENODE

The namenode of the Hadoop HDFS. This is the standard protocol how HDFS clients connect.

Default: localhost:9000

Values: host:port

Parameter change needs a process restart: APPLY

APPLY_FILEOUT_STAGING_DIR

The directory where output files are stored while they are in progress.

Default: OFF

Value: directory + file mask.

Wildcards:

%O table owner

%A table name

%C transaction start SCN

%I object=table id

%X transaction id

%N apply process name

%T process type (=APPLY)

%H thread id

%S plog id

%D ddc name

%E file type (csv/avro)

Note that one file can contain multiple transactions. So %C/%X/%H/%S are determined based on first transaction in the file.

We recommend to use %C to order the output files and add %X for cases when %C is non-unique.

Parameter change needs a process restart: APPLY

APPLY_FILEOUT_TARGET_DIR 

The directory where output files are stored when they are completed.

Default: OFF

Value: directory + file mask.

%X transaction id

%N apply process name

%T process type (=APPLY)

%H thread id

%S plog id

%D ddc name

%E file type (csv/avro)

Note that one file can contain multiple transactions. So %C/%X/%H/%S are determined based on first transaction in the file.

We recommend to use %C to order the output files and add %X for cases when %C is non-unique.

Parameter change needs a process restart: APPLY

APPLY_IGNORE_ERROR_CODES

Automatically ignore specified Oracle errors (ORA- ).

Values: string (delimited by :)

Default: (empty) (Internally ORA-10655 is pre set)

For example, if there is a parent-child relationship and only the parent table is being replicated because the child table does not exist on target, any foreign key constraints being created on the parent-child relationship will be replicated and will result in an ORA-942 table or view does not exist error because the add constraint command doesn't find child table it wants to reference to.

Example:

APPLY_IGNORE_ERROR_CODES 942

This will make Apply ignore all ORA-00942 error codes.

Multiple error codes can be delimited by :

Example:

APPLY_IGNORE_ERROR_CODES 942:955

Parameter change needs a process restart: No

APPLY_LISTEN_INTERFACE

Network interface on which APPLY listens for commands (hostname:port).
Default will depend on what was entered in the Setup Wizard.  

Parameter change needs a process restart: No

APPLY_LOOP_PREVENTION

If set to YES apply process checks originating dbid of the transaction (on which db it was first mined). If it's same as dbid of apply database, apply skips the change. This is useful for two way replications.

  • YES (default)
  • NO

Parameter change needs a process restart: APPLY

APPLY_MSSQL_USER_DB

Deprecated.

Values: string

Default: (empty)

APPLY_PARALLEL_LOAD_DBI

Parameter change needs a process restart: APPLY

APPLY_PEER

What is the corresponding APPLY for this process? If SIMPLE_CONFIG = YES, this is simply set to APPLY.

Parameter change needs a process restart: MINE

APPLY_POSTPONE_LAST_LCR
  • NO (default)
  • YES

If set to YES, then APPLY will postponing the last LCR or SQL until the next SQL for the same object is found. This can sometimes help with (deadlock) locking issues or "APPLY hung" issues. This can also assist if there are killed sessions on the source database and the APPLY is waiting on the detection of the killed process to rollback (or commit).

By setting to YES it means that APPLY is always one SQL behind. This means APPLY always keeps one SQL in each open transaction unapplied. It processes the changes it gets from MINE, but stops short of the last one available so far.

As soon as APPLY receives the commit, it applies even the last SQL. So there is never any data loss, although it can be noticed that APPLY lags behind MINE until the commit arrives. But this is probably most visible for manual test cases (like insert 10.000 rows and see that 9.999 has been applied) because in production systems there is always some activity from the source (and with commits), so this situation is rarely seen.

Value "" meaning: This instructs Dbvisit Replicate to detect if there is ASM of there is no ASM. If ASM was detected → detect SID for ASM automatically and use it, if ASM was not detected → use redo logs on the filesystem.

Value "AUTO" meaning: This instructs Dbvisit Replicate to use ASM, but it should detect the SID for ASM automatically and use it.

Value "OFF" meaning: This instructs Dbvisit Replicate to ignore redo logs in ASM and uses the redo logs on the file system (when they are multiplexed). This is useful when using older versions of ASM such as 10.1 as Dbvisit Replicate only supports ASM version 10.2 and higher. 

Value SOME_OTHER_STRING meaning: This instructs Dbvisit Replicate to use ASM, and use SOME_OTHER_STRING as SID.

Default: "" (empty string).

This is the national character set of the source database. This is relevant only for NCHAR/NVARCHAR2 columns. Only UTF8 and AL16UTF16 values are supported; Oracle expects Unicode values to be specified in UTF16, so if the source database is using UTF8 (specified by this setting), APPLY does the necessary conversion to UTF16. Any other (legacy) mutlibyte character sets are currently not supported.

NLS_LANG

The NLS_LANG variable is set at the APPLY environment and behaves like the NLS_LANG environment does: it sets the language, territory and character set of the APPLY session. The language and territory are not very important (they affect things like Oracle error messages shown), the character set must be set to the source database character set, so the any character strings applied are treated correctly according the character set they are in.

Apart from setting the NLS_LANG to a character set. The values of NLS_LANG can also be:

  • KEEP_UNDEF - ignore the NLS_LANG environment setting
  • KEEP - use the NLS_LANG environment setting

Note: These above 2 settings should be set using the "memory_set" and not the "set" command. Example:

memory_set MINE.NLS_LANG=KEEP_UNDEF

This can be set in the MINE ddc file.

Also see NLS Considerations.

Default will depend on NLS settings of the environment the dbvrep executable was run on.

SCN difference: if the lag between APPLY and MINE exceeds this threshold, an SNMP trap and/or email is sent.

Values: Integer

Default is 10000

Parameter change needs a process restart: Yes

NOTIFY_SEND_HEARTBEAT_TIME24

Times when the overall heartbeat email should be sent. Use 24-hour time format, separate multiple times by colon, e.g. 0700 or 0800:2000. Note that times near to midnight may be skipped, if no check gets scheduled till midnight (see also NOTIFY_INTERVAL_BETWEEN_CHECKS).

Default: 0800:1300

OCI_COMMIT_MODE

Commit options for APPLY sessions (target). Can be either 

  • DEFAULT (default)
  • WAIT IMMEDIATE
  • WAIT BATCH
  • NOWAIT IMMEDIATE
  • NOWAIT BATCH 

The default value is DEFAULT, which is the usual behaviour of commit on Oracle. DEFAULT is the only valid option for Oracle 9i. Option is ignored for non-Oracle databases. Consult with support before setting, as some of the non-default values may lead to data loss in some special cases such as RAC. Setting to NOWAIT BATCH means APPLY will not wait for commit redo to be written to disk. This may improve performance of APPLY, but is not recommended for RAC target systems because during a crash of one of the nodes not all the SCN information of the replication will be up to date. And this may cause data loss in the replication. For RAC target systems set to WAIT IMMEDIATE which means commit wait. For Oracle current versions, DEFAULT is the same as WAIT IMMEDIATE.
