AUTOMOUNT=YES|NO|IMMED

If set to YES and a normal allocation fails because a data set is not online, Tectia will allocate it and request the system to mount it. This requires that the user has read permission to the SSZ.MOUNT facility.

If set to NO, offline data sets are not mounted automatically.

If set to IMMED, Tectia will not attempt the normal allocation, it will request the system to mount the data set immediately.

Default: NO

[NO]AUTOMOUNT|[NO]AUTOM

AUTOMOUNT|AUTOM is equal to AUTOMOUNT=YES.
NOAUTOMOUNT|NOAUTOM is equal to AUTOMOUNT=NO.

AUTORECALL=YES|NO

Defines whether data sets migrated by a storage manager are recalled automatically.

Default: YES

[NO]AUTORECALL|[NO]AUTOR

AUTORECALL|AUTOR is equal to AUTORECALL=YES.
NOAUTORECALL|NOAUTOR is equal to AUTORECALL=NO.

BLKSIZE|B|BLOCKSI=size

Specifies the maximum block size.

Default: none

BLOCKS|BL

Specifies that the space allocation unit is blocks. Equal to SPACE_UNIT=BLKS.

CONDDISP|CO=CATLG|UNCATLG|KEEP|DELETE

Specifies the disposition of the output file when a file transfer ends prematurely (the client or server are alive but disconnected from the other end; for example, when pressing CTRL+C in the client).

[Note]Note

If the client (when transferring to local or client side) or the server (when transferring to remote or server side) dies, they will have no control over the disposition.

The options have the following effects, depending on the file type (MVS or HFS):

  • CATLG: an MVS data set is retained and its name is cataloged. An HFS file is retained.

  • UNCATLG: the name of an MVS data set is removed from the catalog but the data set is retained. An HFS file is retained.

  • KEEP: an MVS data set is retained (if cataloged it will be still cataloged, if uncataloged it will be still uncataloged). An HFS file is retained.

  • DELETE: the name of an MVS data set is removed from the catalog and the space allocated for the data set is released. An HFS file is deleted.

Default: CATLG

CYLINDERS|CY

Specifies that the space allocation unit is cylinders. Equal to SPACE_UNIT=CYLS.

DATACLAS|DA=class

Specifies the data class of a data set.

Default: none

DATASET_SEQUENCE_NUMBER|SEQNUM=number

Identifies the relative position of a data set on a tape volume.

Default: System default

DEFER|DE=YES|NO

Specifies whether data set allocation is postponed from allocation phase to when the data set is opened.

If set to YES data set allocation is postponed until data set is opened.

If set to NO data set is allocated in allocation phase.

Default: NO

[NO]DEFER|DE

DEFER|DE is equal to DEFER=YES.
NODEFER is equal to DEFER=NO.

DIRECTORY_SIZE|M|DI|DIRSZ=size

Specifies the number of 256-byte records in the directory.

Default: 10

EXPIRY_DATE|EXPDT=yyddd|yyyyddd

Specifies the expiration date for a new data set. On and after this date, the operating system can delete or write over the data set.

Default: System default

FILE_STATUS|STATUS=NEW|MOD|SHR|OLD

Defines the status of a data set. If entered, the value will be used when allocating the data set. This attribute corresponds to the first value in the DISP parameter of the JCL DD statement. Possible values are:

  • NEW: Create a data set.

  • MOD: Append to an existing data set. If the data set does not exist, a new data set is created.

  • SHR: Create a read-only data set.

  • OLD: Designate an existing data set.

FILETYPE|FILET=SEQ|JES

Specifies whether to interface with the file system or with the z/OS Job Entry Subsystem (JES).

Using FILETYPE=JES enables the commands put and sput to submit transferred files to the internal reader job queue for execution, and get and sget commands to retrieve spool data sets. To terminate interfacing with JES and return to normal file access, set the file type back to sequential (SEQ), or to an empty string (that is, FILETYPE=). Entering an empty string as file type sets the file type to default.

Default: SEQ

FIXRECFM|FI=length

The data set organization is set to FB and the fixed record length is set to length.

Default: none

JOB_ID|JESID=ID

When in FILETYPE=JES mode, JOB_ID specifies that commands accessing the JES spool, such as get, apply only to jobs with a job ID that matches the supplied ID.

Commands get, sget, and so on, with a job ID can be used to retrieve the spool files for a given job.

JOB_OWNER|JESO=name

When in FILETYPE=JES mode, JOB_OWNER specifies that commands accessing the JES spool, such as ls, and get, and so on, apply only to jobs with owner matching the supplied name.

Default: Current user

JOBNAME|JESJOB=name

When in FILETYPE=JES mode, JOBNAME specifies that commands accessing the JES spool, such as ls, get, and so on, apply only to jobs with job name matching the supplied name.

KEYLEN|KEYL=length

Specifies the length in bytes of the keys used in the data set.

Default: none

KEYOFF|KEYO=offset

Specifies the key offset; the position of the first byte of the key in records of the specified VSAM data set.

Default: none

LABEL_TYPE|LABEL=NL|SL|NSL|SUL|BLP|LTM|AL|AUL

The type of the label for the data set. This attribute corresponds to the first value in the LABEL parameter of the JCL DD statement.

[Note]Note

It is recommended for sites to control the use of BLP and NL tape processing by restricting access to the appropriate resource, using RACF or an equivalent security product.

LIKE=like

Specifies the name of a model data set from which the RECFM, BLKSIZE, and LRECL attributes are to be copied. The name must be the full DSN of a cataloged data set and must be preceded with three underscores.

You must include the TYPE attribute when using LIKE unless you are creating a PS data set and the model is a PS data set.

Default: none

LRECL|R|LR=length

Maximum record length or fixed record length.

Default: 4096 for VSAM, 80 if data set organization is F or FB, otherwise 1024

MGMTCLAS|MG=class

Specifies the management class of a data set.

Default: none

NORMDISP|NOR=CATLG|UNCATLG|KEEP|DELETE

Specifies the data set disposition to be used after a file transfer that ends normally. This attribute corresponds to the second value in the DISP parameter of the JCL DD statement.

Default: CATLG

PRIMARY_SPACE|PRI=space

Primary space allocation for a data set.

Default: none

PROFILE|P|PROF=profile

The file transfer profile specifies the named profile used for the file transfer. The profile name is case-sensitive. With special profile name P=% no profiles are used. This also prevents profile matching based on file name.

Default: none

RECFM|O|REC=recfm

RECFM specifies the data set organization. The possible values are all valid combinations of the following letters:

    F       Fixed
    V       Variable
    U       Undefined
    B       Blocked
    S       Spanned or standard
    M       Machine line printer codes
    A       ASA line printer codes

Default: VB

RECORD_TRUNCATE|U|TRUN=YES|NO

When a record truncation occurs while writing an MVS data set, the system will continue writing the data set if RECORD_TRUNCATE is set to YES; and the system will abort the transfer if RECORD_TRUNCATE is set to NO or omitted.

Record truncation will occur if the length of a transferred record (after code set and line delimiter conversion) is larger than the maximum record length of the data set. Truncation can occur only when TRANSFER_FORMAT is set to LINE or RECORD. Note that the STREAM format does not have any concept of records in transferred data and it will fill out all records to their maximum length.

In the LINE transfer format, the length of a transferred record is the number of characters up to a newline character.

In the RECORD format, the length of a transferred record is given by the 4 byte binary length field which precedes the record.

The maximum length of a data set record depends on the data set organization:

  F and FB - LRECL
  V and VB - LRECL-4
  U        - BLKSIZE
  VSAM     - MAXRECLEN

When Tectia Client aborts writing a data set because of record truncation, it will complete the write operation during which the system observed the truncation. It will write to disk one or more records, at least one of which is truncated. The data set is left on the system.

Tectia Client may write a large amount of data in one write operation, typically 32kB. Several records may be written in the last operation, some of them truncated. Small files may be written to the end of the file, and thus the resulting data set will be equivalent to one written with setting RECORD_TRUNCATE=YES.

Note that some file transfer client programs do not always show the error or warning messages from the server. Using the verbose mode (--verbose, -v) may show more messages from the server.

[Note]Note

When Tectia Client writes a data set with RECORD_TRUNCATE=YES, data loss may occur.

[NO]TRUNCATE|[NO]TRU|[NO]TRUN

TRUNCATE|TRU|TRUN is equal to RECORD_TRUNCATE=YES.
[NO]TRUNCATE|[NO]TRU|[NO]TRUN is equal to RECORD_TRUNCATE=NO.

RETENTION_PERIOD|RET=days

The retention period in days. After the retention period, the data set expires and the operating system can delete or overwrite the data set.

Default: System default

SECONDARY_SPACE|SE|SEC=space

Secondary space allocation for a data set.

Default: none

SIZE|L=size

Size estimate (in bytes) for data set allocation.

Default: 1000000

SPACE_RELEASE|RLSE=YES|NO

When a new data set it allocated, SPACE_RELEASE specifies whether unused disk space will be released. If set to YES, unused disk space of a new data set is released. If set to NO, allocated disk space of a new data set is retained.

Default: YES

SPACE_UNIT|SU=BLKS|TRKS|CYLS|AVGRECLEN

Unit of space allocation for a data set.

Possible values for the space allocation unit are:

  • BLKS: Blocks

  • CYLS: Cylinders

  • TRKS: Tracks

  • AVGRECLEN: Average record length

Default: none

SPACE_UNIT_LENGTH|SUL=length

When SPACE_UNIT=BLKS or SPACE_UNIT=AVGRECLEN, specifies the size of the space allocation unit.

Default: 100 with SPACE_UNIT=AVGRECLEN, none with SPACE_UNIT=BLKS

STAGING|S|STAGE=YES|NO

Specifies whether staging is to be used in the SFTP server when accessing a file or data set.

If set to NO, staging is not used.

If set to YES, staging is used, when needed.

Default: NO

[Note]Note

When staging is used, do not set the _CEE_RUNOPTS environment variable's TRAP option to OFF. If you do, sftpg3 fails to start. The TRAP option is ON by default.

STORCLAS|ST=class

Specifies the storage class of system managed storage.

Default: none

SVC99_TEXT_UNITS|SVC99=string

Dynamic allocation arguments that override or are added to arguments from other file transfer attributes.

Default: none

TRACKS|TR

Specifies that the space allocation unit is tracks. Equal to SPACE_UNIT=TRKS.

TRAILING_BLANKS|TRAIL=YES|NO

Specifies whether to preserve trailing blanks in a transferred data set.

If set to YES, trailing blanks will be transferred. This can be used, for example, to preserve the structure of fixed format data sets when transferring to a Unix-type file system.

If set to NO, trailing blanks will be stripped.

Default: NO

[Note]Note

This option only applies to line-delimited target files (TRANSFER_FORMAT=LINE), not to target unit-record data sets.

[NO]TRAILINGBLANKS|[NO]TRAI|[NO]TRAIL

TRAILINGBLANKS|TRAI|TRAIL is equal to TRAILING_BLANKS=YES.
NOTRAILINGBLANKS|NOTRAI|NOTRAIL is equal to TRAILING_BLANKS=NO.

TRANSFER_CODESET|C|CODESET=codeset

During the transfer the data has the specified code set. codeset is the code set name that is known to the iconv function of the system performing the conversion. The available code sets can be listed by invoking the iconv command at a USS prompt with the -l option:

> iconv -l

Default: none

Example: A Windows SFTP client puts a file to a z/OS data set and gets a data set from z/OS

sftp> site C=ISO8859-1 D=IBM-1047 1
sftp> sput file.txt //DATASET.TXT 2
sftp> sget //DATASET.TXT file.txt 3
1

The z/OS server is told that the code set during transfer is ISO8859-1 and that the data set is stored on the server with the IBM-1047 code set.

2

The server converts the code set from ISO8859-1 to IBM-1047 upon receiving the data.

3

The server converts the code set from IBM-1047 to ISO8859-1 before sending the data.

[Note]Note

The line delimiter information is always given to the host that is capable of performing the conversion, in these cases the z/OS host.

TRANSFER_FILE_CODESET|D|FCODESET=codeset

The data in the data set has the specified code set. codeset is the code set name that is known to the iconv function of the system performing the conversion. The available code sets can be listed by invoking the iconv command at a USS prompt with the -l option:

> iconv -l 

Default: none

TRANSFER_FILE_LINE_DELIMITER|J|FLDELIM=UNIX|MVS|MVS-FTP|DOS|MAC|NEL

The transfer file line delimiter specifies the newline convention used in the (source or destination) file. Possible values are:

  • UNIX: The line delimiter used in the file is LF (\n, 0x0A).

  • MVS: The line delimiter used in the file is NL (\n, 0x15). When writing to a data set, also the CR (\r, 0x0D) code is considered as the End of Line.

  • MVS-FTP: When reading MVS data sets, each record in the data set is treated as a line. The transfer line delimiter is appended to the record. Any control characters in the record data are preserved.

    When reading data sets with printer control characters, the control characters are preserved in the output.

    If the code set conversion is specified either by TRANSFER_TRANSLATE_TABLE|E, or by TRANSFER_CODESET|C and TRANSFER_FILE_CODESET|D, the appended delimiter is the delimiter specified by TRANSFER_LINE_DELIMITER|I, TRANSFER_CODESET|C, or TRANSFER_TRANSLATE_TABLE|E. If no code set conversion is requested, the delimiter is defined by the code set of the data set. By default it is EBCDIC.

    You can specify code sets by defining TRANSFER_FILE_CODESET without TRANSFER_CODESET. For example, to have a DOS delimiter in Unicode (x'000D000A') appended to the records, set "I=DOS,J=MVS-FTP,D=UCS-2", and to have a Unix delimiter in ISO Latin 1 (x'0A'), set "I=UNIX,J=MVS-FTP,D=ISO8859-1".

    Do not use this when writing data sets.

  • DOS: The line delimiter used in the file is CRLF (\r\n, 0x0D 0x0A).

  • MAC: The line delimiter used in the file is CR (\r, 0x0D).

  • NEL: The line delimiter used in the file is Unicode New Line (0x85).

Default: none

[Note]Note

The line delimiter information should be given to the host that is capable of performing the conversion, such as a host with a Tectia.

Line delimiter conversion is implemented for single byte code sets only.

For the line delimiter conversion to happen, both TRANSFER_LINE_DELIMITER|I and TRANSFER_FILE_LINE_DELIMITER|J must be specified.

Example: a z/OS Tectia SFTP client sends a data set to a Windows host and copies the file back from Windows

In this example, the code set is also converted.

sftp> lsite I=dos J=mvs                1
sftp> lsite C=IBM-437 D=IBM-1047       2
sftp> sput //DATASET.TXT file.txt      3
sftp> sget file.txt //DATASET.COPY.TXT 4
1

Transfer line delimiter is set to DOS and transfer file line delimiter to MVS.

2

Transfer code set is set to IBM-437 and transfer file code set to IBM-1047.

3

The z/OS client inserts a NL (0x15) character after each record. The line delimiter conversion converts all NL:s to CRLF (0x0D 0x0A) characters, which remain unchanged in the code set conversion.

4

The CRLF line delimiters are converted to LF characters, which are converted to NL characters in the code set conversion. Each NL character (and CR character, if there are any in the data) causes the current record to be written out and a new record started.

TRANSFER_FORMAT|F|FORMAT=LINE|STREAM|RECORD

The byte stream consists of the bytes that are transferred as payload in the SFTP protocol packets. The byte stream has one of the following formats: LINE, STREAM or RECORD. All three formats may have data consisting of text, non-text data, or a mixture of these.

When writing an MVS data set, a record that is longer than the maximum or fixed record length will cause an error unless RECORD_TRUNCATE is set to YES, in which case the record will be truncated. When writing to data sets with fixed record lengths, short records will be filled with binary zeroes if you use the record transfer format and with blanks if you use the line transfer format.

  • LINE: The line transfer format is record-based. It uses delimiter characters to mark the end of a record. The delimiter character may be a Carriage Return (CR) or a Newline (NL). When writing to or reading from data sets with ASA control characters, a Form Feed (FF) is also treated as a delimiter. The table below shows the values of these characters in EBCDIC and ASCII. Data sent to Tectia Client in the line transfer format must be in EBCDIC or must be converted to EBCDIC during the transfer.

    Delimiter          EBCDIC                    ASCII
                       Name  Dec   Oct   Hex     Name  Dec   Oct   Hex
    \r Carriage Return CR    13    015   0x0D    CR    13    015   0x0D
    \n Newline         NL    21    025   0x15    LF    10    012   0x0A
    \f Form Feed       FF    12    014   0x0C    FF    12    014   0x0C

    Note that ASCII does not have a NL character, instead Line Feed (LF) is used to delimit lines.

    Avoid conversions that transform an ASCII Line Feed (LF/10/012/0x0A) into an EBCDIC Line Feed (LF/37/045/0x25) or an EBCDIC Newline (NL/21/025/0x15) into an ASCII Next Line (NEL/133/0205/0x85).

    Be aware that sending a double delimiter, e.g. \r\n or \n\r, to Tectia Client will result in two records. The TRANSFER_LINE_DELIMITER and TRANSFER_FILE_LINE_DELIMITER attributes can be used to cause the Tectia Client server or client program to convert between the line delimiter conventions.

    Tectia Client sends \n as the Server Newline Convention in the server initialization SFTP protocol message.

    When transferring line format data to and from MVS files with ASA line printer control characters, Tectia Client will convert between the control characters and line delimiter characters, as described in the IBM z/OS XL C/C++ Programming Guide, Chapter "Using ASA Text Files".

    To transfer records without changing the ASA code, use the STREAM or RECORD transfer format, or define the data set using a DD card and specify RECFM=FB or RECFM=VB.

    Data sets transferred in the line transfer format and recreated on a mainframe will not necessarily be identical.

  • STREAM: The stream transfer format contains the data bytes of the data set but no structural information. If a data set with a fixed record length is transferred with the stream format and recreated with the same record length, the record structure will be preserved. Variable length records will not be recreated properly if transferred with the stream format.

  • RECORD: The record transfer format is record-based. Each record is preceded by a length field consisting of a 4- byte big-endian binary integer, which indicates the number of data bytes in the record. Note that the format is not the same as the record descriptor word in data sets with RECFM=V or RECFM=VB.

    A data set that is transferred with the record transfer format can be recreated as any data set type.

Default: LINE.

TRANSFER_LINE_DELIMITER|I|LDELIM=UNIX|MVS|MVS-FTP|DOS|MAC|NEL

The transfer line delimiter specifies the newline convention used in the data that is transferred over the connection. Possible values are:

  • UNIX: The line delimiter on the connection is LF (\n, 0x0A).

  • MVS: The line delimiter on the connection is NL (\n, 0x15). If the data is converted from EBCDIC to ASCII, the NL becomes a LF (\n, 0x0A).

  • MVS-FTP: When writing to a data set, only the LF (\n, 0x0A) control codes are considered as an End Of Line. Any CR (\r, 0x0D) codes are preserved as data in the record.

    When writing data sets with ASA printer control characters, the first character on each line is used as the ASA character.

    Do not use this when reading data sets.

  • DOS: The line delimiter on the connection is CRLF (\r\n, 0x0D 0x0A).

  • MAC: The line delimiter on the connection is CR (\r, 0x0D).

  • NEL: The line delimiter used in the file is Unicode New Line (0x85).

Default: none

[Note]Note

The line delimiter information should be given to the host that is capable of performing the conversion, such as a host with a Tectia.

TRANSFER_MODE|X|MODE=BIN|TEXT

The transfer mode specifies whether code set and line delimiter conversions are performed. The available values are:

  • BIN: Code set and line delimiter conversions are not performed.

  • TEXT: Code set and line delimiter conversions are performed.

Default: none

[Note]Note

If TRANSFER_MODE is not given but both TRANSFER_CODESET and TRANSFER_FILE_CODESET or TRANSFER_TRANSLATE_TABLE are present conversions are performed.

TRANSFER_TRANSLATE_DSN_TEMPLATES|A|XDSNT=templates

templates specifies the search templates for the translate table. Write '%T' to show the point where the translate table name (see above) is to be inserted. Delimit the templates with a plus character. The data set name templates must not contain slashes, instead they must be preceded by two or three underscores.

The first translate table data set that is found is used to perform the code conversion.

[Note]Note

The translate table must translate line delimiters into EBCDIC NL characters. See TRANSFER_FORMAT.

Default: none

TRANSFER_TRANSLATE_TABLE|E|XTBL=table

TABLE is the name of the table that specifies the code set conversion. If set, this attribute overrides the transfer code set and file code set attributes. The table is always applied in the normal direction, that is, the first character array is used for incoming (from the line to the data set) data and the second array for outgoing data. If the opposite translation is needed, e.g. the data set contains ASCII and should be transferred as EBCDIC, you (or your system programmer) can prepare a table data set with the character arrays in reversed order (e.g. with the system utility CONVXLAT or by editing an existing translate data set).

TYPE|T=PS|PO|PDS|POE|PDSE|GDG|HFS|VSAM|ESDS|KSDS|RRN

Specifies the type of a data set when the data set is created. The available values are:

  • PS: The type of the created data set is PS.

  • PO|PDS: The type of the created data set should be PDS. Note that in order to create a PDS, you need to specify the DIRECTORY_SIZE parameter. If you do not specify the directory size, a sequential data set - not a partitioned data set - is created.

  • POE|PDSE: The type of the created data set is PDSE.

  • GDG: The type of the created data set is GDG.

  • HFS: The type of the created data set is HFS.

  • VSAM: The type of the created data set is VSAM.

  • ESDS: The type of the created data set is VSAM ESDS.

  • KSDS: The type of the created data set is VSAM KSDS.

  • RRN: The type of the created data set is VSAM RRN.

Default: PO, if data set name includes member, otherwise PS

UNIT|UN=unit

The name of the device or group of devices that the data set will reside on (or does reside on, if it already exists). The maximum length of unit is 8 characters. If the value exceeds the maximum length, it is truncated to 8 characters.

It is also possible to specify a device address. Precede a four digit address with an underscore.

Default: none

UNIT_COUNT|UC|UNC=number

Specifies the number of devices for the data set. This attribute corresponds to the second value in the UNIT parameter of the JCL DD statement.

Default: System default

UNIT_PARALLEL|UNP=YES|NO

Asks the system to mount all the volumes for the data set in parallel. This attribute corresponds to the character 'P' in the second value in the UNIT parameter of the JCL DD statement.

Default: System default

VOLUME_COUNT|VC|VOLCNT=number

Specifies the maximum number of volumes that an output data set requires. This attribute corresponds to the volume count value in the VOLUME parameter of the JCL DD statement.

Default: System default

VOLUMES|VO|VOL=vol1+vol2+...

A plus sign (+) separated list of volumes a data set will reside on (or does reside on, if it already exists).

Default: none
