3 Collector Parameters
Note:
Collector parameters are specified by a dash (-) followed by a letter and optional arguments. The Collector Parameters are case-sensitive.Collector Parameters
Most Collector parameters are entered in the Extract parameter file, using the PARAMS
collector_params
option of the RMTHOST
parameter. The Manager automatically sends some of these parameters when it starts the Collector, such as -k and ENCRYPT
key and KEYNAME
options entered by the user.
The Collector parameters discussed here are for a Collector running on a remote NonStop system. For Collector parameters that run on other platforms, see Collector Parameters.
-
-
PROCESS
process_name
-
The name of the NonStop TCP/IP process.
-
-BULKIO
-
Results in Collector writing data in 28K blocks, rather than 4K. Setting
-BULKIO
can increase total throughput of the Collector and reduce overhead significantly. -
-BULKIOLEN
-
Use
BULKIOLEN
to customize the block size Collector should use when writing data. Increasing the block size used by Collector can contribute a net performance gain by increasing total throughput. Block sizes may be indicated in bytes or kilobytes, but the Collector only recognize sizes that are multiples of 2. If you choose a block size between 2 and the next multiple,BULKIOLEN
automatically rounds your specification down. -
-
b
backup_cpu
-
Runs the Collector backup process started in
backup_cpu
. This option is only for static servers. It is not valid for dynamic servers, which are persistent processes that will be restarted if the process has a failure. -
-B
-
-DEBUG
-
Starts the Collector in
DEBUG
mode to allow the user to analyze the actions of the program code. -
-EMSEMPHASIS
type
-
Controls whether or not emphasis will be turned on for certain types of messages coming from EMSCLNT on open systems.
type
can be one of the following:-
CRITICAL
-
Turns emphasis on for
CRITICAL
orWARNING
messages as well asFATAL
messages. -
FATAL
orERROR
-
Turns emphasis on only for
FATAL
messages.
The default is
CRITICAL.
-
-
-
ENCRYPT
encrypt_type
-
The type of encryption being passed from the Extract process, as specified with the
RMTHOST
parameter in the Extract parameter file.Valid values:
-
GGS
-
BLOWFISH
If using
BLOWFISH
, also specify the -KEYNAME
option. For more information about Oracle GoldenGate security, see Using Encryption. -
-
-f
-
Always forces file writes to be flushed to disk before returning a success status to the Extract process.
By default, the file system buffers the I/O because it is more efficient than flushing to disk with every operation. Generally, the performance benefits outweigh the small risk that data could be lost if the system fails after an I/O is confirmed successful, but before the buffer actually is flushed to disk. Use
-f
if this risk is unacceptable, with the understanding that it can compromise the performance of Oracle GoldenGate. -
-
HOMETERM
terminal
-
Identifies the home terminal for the Collector.
-
-k
-
Directs Collector to terminate when the Extract process that it is serving disconnects. This option is used by the Manager process when starting the Collector process.
-
-
KEYNAME
name
-
Specifies a key name defined in the local
ENCKEYS
lookup file.name
is the name of a key in a lookup file on the target system. For more information about Oracle GoldenGate security, see Using Encryption. -
-
l
file_name
-
Directs the Collector to log to
file_name
. The name should be fully qualified. -
-m
number
-
Specifies the maximum number of files to allocate.
-
-
NOFLUSHCACHE
|FLUSHCACHE
-
Turns on or off the flushing of the disk cache.
-
-p
port_number
-
A TCP/IP port number on which the Collector listens for connections from the Extract process. The default is port
7819
. -
-t
-
Turns on TCP tracing to write detail to EMS on socket operations. It is recommended that you use this parameter only when requested by Oracle GoldenGate Support.
-
-TCPSTATS
-
Specifies that TCP statistics should be printed at file rollover.
-
-v
-
Specifies that NonStop Collector processes use EMS logging.
QSAM Configuration Parameters
For OS/390 QSAM files, both fixed-length and variable-length, you can specify a configuration file on the OS/390 platform to set certain file creation characteristics. Indicate the location of this file with the -P
collector parameter.
You can also specify QSAM file creation characteristics using the RMTBATCH
Extract program parameter. The syntax is:
RMTBATCHfile_spec
,option
[,option
, ...];
-
file_spec
-
A file name or wildcard for the incoming file. Any files that match
file_spec
are assigned the file creation rules you specify withoption
. If a file name is satisfied by more than oneRMTBATCH
entry in the configuration file, the last entry is used. -
option
-
One of the following.
-
CLOSEACTION
"system_command
" -
Submits a shell script or system command to the system upon file close, when close was a result of completed processing of the corresponding source file (indicated by a "file close on source" message).
The Collector waits for the command to complete. To return control to the Collector immediately, specify a "nowait" type operation in the script or command (as with the
&
in UNIX). -
COMMENT
-
Lets you insert comments. Anything on the same line after
COMMENT
is ignored. Comments can also begin with two hyphens (--). -
SPACE
(primary_quantity
,secondary_quantity
,unit
) -
Mandatory parameter. Requests space for a new data set.
-
TARGETFTYPE {QSAMV | QSAMF}
-
Mandatory parameter for QSAM files. Specify
QSAMV
for variable-length MVS QSAM files orQSAMF
for fixed-length MVS QSAM files. -
TARGETRECLEN
record_length
-
Mandatory parameter for QSAM files. Specify the length in bytes of a fixed-length record or the maximum length in bytes for variable-length records.
record_length
can be from1
to32760
. -
TARGETBLKSIZE
block_length
-
Parameter for QSAM files. Specify a multiple of the record length for fixed-length records, or the maximum record length +4 for variable-length records.
block_length
can be from 1 to 32760. -
VOLUME
serial_number
-
Mandatory parameter. Identifies the serial number of the volume on which the target data set will reside. Specify only one volume serial number.
-
Example
The following example matches all source file names. It creates fixed length records of 100
bytes, in blocks of 1000
bytes (10 records per block), with a volume serial number for the new data set of 123456
, and allocates an initial space of 20
tracks. If more space is needed, it is allocated in increments of 10
tracks.
RMTBATCH *, TARGETFTYPE QSAMF, TARGETRECLEN 100, TARGETBLKSIZE 1000, VOLUME 123456, SPACE (20,10,TRK), CLOSEACTION "type * %";
