The STORE function loads one or more files into an existing database using output produced by the RESTRUCTURE functions.
If the ALLFILES parameter is specified, all files contained on the input dataset are stored. If ALLFILES is not specified, only those files specified by FILE parameters are stored.
One or more files may be specified with FILE parameter statements, even when ALLFILES is also specified. The STORE function loads each file specified with a FILE statement according to the definition contained in any subparameters immediately following that file's FILE statement. All other files are loaded according to their existing definitions.
If existing files in the database are to be overwritten, the OVERWRITE parameter must be supplied.
Notes:
This document covers the following topics:
ACRABN specifies the beginning RABN for the file's address converter extent. If this parameter is omitted, ADAORD assigns the starting RABN. The space requested must be available in one extent.
ALLFILES causes all files in the input dataset to be stored in the database. If ALLFILES is not supplied, only those files are stored for which FILE parameters have been specified.
If the input dataset contains files that are coupled or part of an expanded file and the related files are not in the dataset, ERROR-138 is returned indicating an inconsistent file list. You must add the related files before the STORE function will execute successfully.
ALLOCATION specifies the action to be taken if file extent allocations cannot be obtained according to the placement parameters ACRABN, DSRABN, NIRABN, or UIRABN.
By default (that is, ALLOCATION=FORCE), the utility terminates with error if any file extent allocation cannot be met according to RABN placement parameters.
If ALLOCATION=NOFORCE is specified and any allocation with placement parameters fails, the utility retries the allocation without the placement parameter.
ASSOPFAC specifies the new Associator block padding factor. The number specified represents the percentage of each Associator block not to be used during the reorder process. A value in the range 1-90 may be specified. The remaining number of bytes after padding must be greater than the largest descriptor value plus 10.
If this parameter is omitted, the current Associator padding factor in effect for the file is used.
Note:
The value for the ASSOVOLUME parameter must be enclosed in
apostrophes.
ASSOVOLUME identifies the volume on which to allocate the file's Associator space (the AC, NI, and UI extents). If the requested number of blocks cannot be found on the specified volume, ADAORD allocates the remaining blocks on other volumes according to its default allocation rules.
If ACRABN, UIRABN, or NIRABN is specified, ADAORD ignores the ASSOVOLUME value when allocating the corresponding extent type.
If ASSOVOLUME is not specified, the file's Associator space is allocated according to ADAORD's default allocation rules.
If either ALLFILES is specified or the FILE parameter specifies the checkpoint file, CHECKPOINT stores the checkpoint file from the DDFILEA/FILEA tape in the database, making that file the new checkpoint file. The new checkpoint file must have the same file number as the old checkpoint file.
If the CHECKPOINT parameter is not specified, the checkpoint file on the FILEA/DDFILEA tape is not stored in the database, even though the checkpoint file was specified by a FILE parameter or the ALLFILES parameter was specified.
DATAPFAC specifies the new Data Storage padding factor, which is the percentage of each Data Storage block reserved for record expansion when the file is reordered. A value in the range 1-90 may be specified (see the ADALOD LOAD DATAPFAC parameter discussion for more information about setting the padding factor). If this parameter is omitted, the current padding factor for the file is used.
Note:
The value of the DATAVOLUME parameter must be enclosed in
apostrophes.
DATAVOLUME specifies the volume on which the file's Data Storage space (DS extents) are allocated. If the number of blocks requested with DSSIZE cannot be found on the specified volume, ADAORD allocates the remaining blocks on other volumes according to its default allocation rules.
If DSRABN is specified, DATAVOLUME is ignored for the related file.
If DATAVOLUME is not specified, the Data Storage space is allocated according to ADAORD's default allocation rules.
DSDEV specifies the device type to be used for the file's Data Storage. The specified device type must already be defined to Adabas, normally when the database was created or by the ADADBS utility's ADD function.
If this parameter is not specified, ADAORD attempts to allocate the file on the device type used before restructuring.
The beginning RABN for the Data Storage extent for the specified file. If this parameter is omitted, ADAORD assigns the starting RABN.
Specifying DSRELEASE releases unused Data Storage (DS) blocks belonging to the specified file. If DSRELEASE is not specified, ADAORD allocates at least the number of DS blocks that were allocated before the file was reordered.
Note:
Adabas calculates the file extent size using any changed padding
factor or blocksize values before the file is reordered.
DSSIZE specifies the number of blocks or cylinders to be allocated for the Data Storage. A block count must be followed by "B" (for example, 2000B).
If this parameter is omitted, ADAORD will compute the file extent size (in blocks) in proportion to an increase or decrease in the DATAPFAC padding factor used.
EXCLUDE lists the numbers of the files to be excluded from STORE processing; that is, the files that are not to be stored.
The parameter is optional: if not specified, no files are excluded. A file number may be listed only once.
The EXCLUDE parameter may be specified only if ALLFILES is also specified.
The EXCLUDE parameter is provided for use in recovery jobs built by the Adabas Recovery Aid (ADARAI).
FILE specifies the file to be stored. A separate statement must be provided for each file to be processed, followed by ADAORD statements containing the relevant parameters for that file.
If you specify a file that is coupled or part of an expanded file and you do not also specify the related files, ERROR-138 is returned indicating an inconsistent file list. You must add the related files before the STORE function will execute successfully.
INDEXCOMPRESSION indicates whether the index for the file is rebuilt in compressed or uncompressed form. A compressed index usually requires less index space and improves the efficiency of index operations in the Adabas nucleus.
If INDEXCOMPRESSION is not specified, the default is the form of the file at the time of the corresponding restructure operation.
ISNSIZE specifies whether ISNs in the file are to be 3 or 4 bytes long. The default is the value currently used for the file; this value is stored in the file control block (FCB).
Note:
It is not possible to change the ISNSIZE of a physically coupled
file using ADAORD.
The LIP parameter can be used to decrease the number of Associator I/O operations when recreating the address converter. For best performance, specify a size that accepts all ISNs of the largest file to be processed.
LIP specifies the size of the ISN pool for containing ISNs and their assigned Data Storage RABNs. The value may be specified in bytes as a numeric value ("2048") or in kilobytes as a value followed by "K" ("2K"). The default for LIP is 16384 bytes (or 16K).
The length of one input record is ISNSIZE + RABNSIZE. Thus the entry length is at least 6 bytes (the ISNSIZE of the file is 3 and the RABNSIZE of the database is 3) and at most 8 bytes (the ISNSIZE is 4 and the RABNSIZE is 4).
MAXISN specifies the highest ISN which may be allocated for the file. This value must be greater than the current TOPISN value displayed in the ADAREP database report.
ADAORD uses the specified value to calculate the address converter space required. If this parameter is omitted, the current MAXISN value for the file is retained.
Use the MAXRECL parameter to change the maximum record length, after compression, permitted in the file. Specifying MAXRECL has two effects:
The DATA dataset for the file can be allocated only to devices that support the specified length.
If the file contains Data Storage records that exceed the specified length, ADAORD abends and prints ERROR-126 "Data Storage record too long".
If MAXRECL is not specified, there are two possibilities for the default value:
If the maximum compressed record length before the file was restructured was the default ADALOD MAXRECL value, then DATA is allocated to a device arbitrarily, and the new maximum record length is derived from the device type;
Otherwise, the maximum compressed record length does not change.
The beginning RABN for the file's normal index extent. If this parameter is omitted, ADAORD assigns the starting RABN.
Specifying NIRELEASE releases unused normal index (NI) blocks belonging to the file. If NIRELEASE is not specified, ADAORD allocates at least the number of NI blocks that were allocated before the file was reordered.
Note:
Adabas calculates the file extent size using any changed padding
factor or blocksize values before the file is reordered.
The number of blocks or cylinders to be allocated for the normal index. The specified value cannot be larger than the largest single contiguous RABN area available; specifying blocks (a number of blocks followed by "B") is therefore recommended.
If this parameter is omitted, ADAORD computes the file extent size (in blocks) in proportion to an increase or decrease in the ASSOPFAC padding factor used.
If this parameter is omitted and the INDEXCOMPRESSION parameter is specified, the ADAORD index size calculation does not consider the change in index size because ADAORD has no knowledge of the compression rate to be expected. Thus, ADAORD may allocate an index smaller than required causing secondary index extent allocations; or larger than necessary.
When an error is encountered while the function is running, the utility prints an error message and terminates with user abend 034 (with a dump) or user abend 035 (without a dump).
If NOUSERABEND is specified, the utility will not abend after printing the error message. Instead, the message "utility TERMINATED DUE TO ERROR CONDITION" is displayed and the utility terminates with condition code 20.
If a file to be stored already exists in the database, ADAORD terminates with an error message unless the OVERWRITE parameter has been specified.
SECURITY stores the security file from the DDFILEA/ FILEA tape, making that file the new security file for the database. The new file must have the same number as the old security file.
If SECURITY is omitted, the security file on the FILEA/ DDFILEA tape is not stored in the database, even if it is specified by a FILE parameter or the ALLFILES parameter is specified.
This parameter tests the operation syntax without actually performing the operation. Only the syntax of the specified parameters can be tested; not the validity of values and variables.
Specify the TRIGGER parameter to store the trigger file from the DDFILEA/FILEA tape as the new trigger file for the database. The new trigger file must have the same file number as the old trigger file.
When the TRIGGER parameter is not specified, the trigger file on the DDFILEA/FILEA tape is not stored in the database, even if it is specified by the FILE or ALLFILES parameter.
UIRABN specifies the beginning RABN for the upper index extent of the file. If this parameter is omitted, ADAORD assigns the starting RABN.
Specifying UIRELEASE releases unused upper index (UI) blocks belonging to the file. If UIRELEASE is not specified, ADAORD allocates at least the number of UI blocks that were allocated before the file was reordered.
Note:
Adabas calculates the file extent size using any changed padding
factor or blocksize values before the file is reordered.
UISIZE specifies the number of blocks or cylinders to be allocated for the upper index. A block count must be followed by "B" (for example, 2000B).
If this parameter is omitted, ADAORD computes the file extent size (in blocks) in proportion to an increase or decrease in the ASSOPFAC padding factor used.
If this parameter is omitted and the INDEXCOMPRESSION parameter is specified, the ADAORD index size calculation does not consider the change in index size because ADAORD has no knowledge of the compression rate to be expected. Thus, ADAORD may allocate an index smaller than required causing secondary index extent allocations; or larger than necessary.
ADAORD STORE FILE=14,OVERWRITE
File 14, as unloaded by one of the RESTRUCTURE or the REORDB functions, is to be stored into an existing database. If the file already exists, it is deleted before being stored.
ADAORD STORE FILE=1,OVERWRITE ADAORD FILE=2,OVERWRITE ADAORD FILE=3,OVERWRITE
Files 1, 2 and 3 are written to the existing database. Old files 1, 2 and 3 are deleted.
ADAORD STORE OVERWRITE,ALLFILES ADAORD FILE=1,ACRABN=1000,NIRABN=2200 ADAORD FILE=2,MAXISN=500000 ADAORD FILE=4,ASSOPFAC=5,DATAPFAC=20,DSSIZE=5B,DSRABN=1
All files unloaded by the RESTRUCTURE function are to be stored into an existing database. The address converter for file 1 is to begin with RABN 1000. The normal index for file 1 is to begin with RABN 2200. The MAXISN for file 2 is to be set to 500,000. The following assignments are made for file 4: the Associator block padding factor is set to 5 percent; the Data Storage block padding factor is set to 20 per cent; a new DSSIZE of 5 cylinders is assigned starting at RABN 1.
All other files contained in the input dataset are restored with their default values. If a file already exists, it is deleted before the new file is stored.
ADAORD STORE ALLFILES,CHECKPOINT ADAORD EXCLUDE=20,10
All files from the input dataset (including the checkpoint file) are stored. However, files 10 and 20 are excluded; that is, not stored.
ADAORD STORE ALLOCATION=NOFORCE ADAORD FILE=10 ADAORD DSRABN=12345
File 10 is stored in the database. Its data storage is allocated beginning at RABN 12,345. If this allocation is not possible because the space is occupied by another file, ADAORD retries the allocation anywhere in the database's data storage.
