Hello

I try to find recommendations to design an Haspindx file (blksize and total size) in relation with the number and size of the syslog datasets in the spool.

I looked into the SDSF Operation and Customization Guide, on the Redbooks site and some other places ... and I fail.

Question

Does anybody have an idea ?

Thanks in advance

Denis,

Sample job ISFISALC contains an allocation for the ISF.HASPINDX data set.

The space required for the HASPINDX data set varies based on the number of SYSLOG data sets on the spool and the number of records within each data set. The HASPINDX block size determines how many data sets can be processed; the larger the block size, the more data sets it can contain. The HASPINDX space determines how many syslog records can be processed; the more space, the more records that can be recorded.

For most installations, the SDSF default block size of 4096 and a space of 5 cylinders will be adequate. The space must be contiguous. The values can be changed at any time after SDSF installation if the HASPINDX data set becomes full.

Read about it here

Thanks for your quick answer.

Anyway, as I said, I already read this book and the information is not precise.

Is there anywhere a calculation to evaluate the size and blksize or should I go blind, that is :
- try
- and see
- and correct
- and retry
- and see again
- and correct again
- and so on ...

We have up to 6 million line of SYSLOG at any one time and our HASPINDX is 6 cyls. Don't make it so difficult and just allocate 5 cyls unless you know your SYSLOG datasets will be very large.

Thank you
I'm just surprised that IBM don't give more info.
In other cases, the docs are more detailed ...
