How to Use

You can execute this command in either Single User or Multi-User mode. Execute the INIT function with the following command format:

►►─ INIT AREA=LXX,BLKSIZE=nnnnnn ─┬─────────────┬─┬─────────────────┬─────────►
                                  └─ ,BLOCKS=n ─┘ └─ ,TSN=xxxxxxxx ─┘

 ►─┬─────────────────────────┬────────────────────────────────────────────────►◄
   └─ ,VARIABLE= ─┬─ NO ◄ ─┬─┘
                  └─ YES ──┘

Command

INIT

Invokes the function to format areas for CA Datacom/DB use.

Required Keywords

AREA=LXX

Identifies the area to be formatted as the Log Area.

,BLKSIZE=

Indicates the logical block size. CA Datacom/DB uses this value and the BLOCKS= value to determine the physical block size. If the specified BLKSIZE= value is not evenly divisible by the BLOCKS= value, DBUTLTY uses the lowest multiple of the BLOCKS= value which is greater than the specified BLKSIZE= value. The resulting physical block size may not be larger than 32760. See the BLOCKS= keyword.

Note: For a variable LXX, the BLKSIZE must be 32760. For a fixed length LXX, a size of one-half track is commonly used.

Valid Entries:

An integer from 16384 to 98280

Default Value:

(No default)

Optional Keywords

,BLOCKS=

Specifies the number of physical blocks per logical block. BLOCKS= may not be 2 or 3 if the LXX is variable.

Valid Entries:

An integer from 1 to 3

Default Value:

1

,TSN=

Specifies the starting number for transaction sequence numbers (TSNs).

If you are running with more than one Multi-User Facility against the same data areas, you should specify a different starting sequence number for each Multi-User Facility to ensure that the sequence numbers are not duplicated.

The DBUTLTY REPORT AREA=LXX and RESTART reports print the highest TSN previously used.

Valid Entries:

A hexadecimal value from 00000000 to FFFFFFFF

Default Value:

00000000

,VARIABLE=

Specifies whether you want to use the variable Log Area (LXX) block size feature (for details see Variable Log Area (LXX) Block Size). Specify YES to use the feature. NO is the default.

Valid Entries:

YES or NO

Default Value:

NO
