SMPLOG

ddname
SMPLOG.
Use
The SMPLOG data set (LOG) contains time-stamped records of SMP/E processing. The records in this data set can be written automatically by SMP/E or added by the user through the LOG command. The data set also contains messages issued by SMP/E, as well as detailed information about data set allocation.
Attributes
Sequential; BLKSIZE=514-32000, RECFM=VB, DISP=MOD.
  • The BLKSIZE value determines how many records are written to the LOG at one time. As a block is filled, it is written to SMPLOG.

    If BLKSIZE is less than 514, SMP/E uses the default of 3200.

  • DISP=MOD must be specified to maintain a cumulative history of SMP/E processing.
  • SMP/E uses LRECL=510 in allocating the SMPLOG data set.
Device
Tape or direct access.
Note:
  1. Important: If the data set allocated to the SMPLOG DD statement has the wrong data set attributes, SMP/E will open the data set for output processing with acceptable attributes. This action will overlay the contents of the data set.
  2. Each zone should have its own SMPLOG data set.
  3. A secondary log data set (SMPLOGA) should be defined to hold log data when the SMPLOG data set is full. Otherwise, the extra log data is written to the SMPOUT data set, with the date and time stamp encrypted.
  4. SMPLOG should be updated only by the LOG command or by processing for other SMP/E commands.
  5. Because some messages are longer than in earlier releases of SMP/E, you may need to increase the size of any data sets used for SMP/E messages (such as SMPOUT). How much more space you need depends on the current size of these data sets and which messages are issued. To start, you may want to allocate new data sets twice the size of the old ones.
  6. Make sure that DDDEF SMPCNTL is not NULL.
