Start Directory Dump

Retrieves information about the entries in the temporary or permanent directories. The snapshot of the entries either in the specified directory or ASP. The collected information includes extent details, segment details, segment type, object type and subtype, object name, library name, and some heap details.



 

Directory dump name	- the name of the collection
Directory dump library	- the library to contain the directory dump collection - data will be placed in files name QASCDD* and the members are specified as the name of the collection
Directory type	- T (contents of the temporary directory will be dumped) - P (contents of the permanent directory will be dumped for all of Sysbase, ASP's 1-32 - I (contents of the permanent directory will be dumped for a single ASP)
ASP number	- specifies the ASP number to have its permanent directory dumped - 0 (temporary or permanent directory is being dumped) - 1-255 (the ASP number)
Job queue name/library	- what job queue to submit the job
Number of jobs	- how many jobs to run in the background - job will be named QSCDIRDnnn, where nnn is a number
Run priority of jobs	- run priority

Either save the directory dump library for later analysis or use the Query Directory Dump option to analyze the collected data.


Query Directory Dump

The command produces reports against a data set produced by either the Start Directory Dump function or Compare Directory Dumps function.




 

Directory dump name	- the directory dump name to run the query against - this directory dump name was specified when the option Start Directory Dump was used
Directory dump library	- the library that contains the directory dump name
Job queue name/library	- what job queue to submit the job
Run priority of jobs	- priority of the batch job
Top contributors	- rank the xxx top contributors
Top ranking	- xxx for top rankings

To view the results use command DSPPFM FILE(XXXXXXXXXX/DDREPORT) MBR(YYYYYYYYYY) where XXXXXXXXXX is the directory dump library and YYYYYYYYYY is the directory dump name.


Compare Directory Dump

Takes two directory dump data sets collected by the Query Directory Dump function and produces a new data set that includes only new segments or extents or those that had growth.


 

Directory dump one name	- the older data set name
Directory dump one library	- the older data set library
Directory dumps two name	- the new data set name
Directory dumps two library	- the new data set library
New directory dump name	- the results name
New directory dump library	- the results library to contain the results directory dump name

Analyze the results with the Query Directory Dump function.


Copy Directory Dump

Copies a directory dump data set from one location to another.


 

Directory dump name	- the directory dump name to be copied
Directory dump library	- the directory dump library containing the directory dump name to be copied
New directory dump name	- the new directory dump name
New directory dump library	- the new library to contain the new directory dump name

Remove Directory Dump

Deletes the data related to a directory dump data set.



 

Directory dump name	- directory dump name to be deleted
Directory dump library	- directory dump library containing the directory dump to be deleted

Create Directory Dump Sample

The function retrieves a random list of segments that match the specified criteria. It essentially provides a reverse lookup for data seen on the Query Directory Dump reports to the actual segments, thus allowing access to the full details.


 

Directory dump name	- the directory dump name to be queried
Directory dump library	- the library containing the directory dump name
Segment type	- segment type to be queried (SEGTYPE)
Object type	- object type to be queried (OBJTYPE)
Segment size	- segment size to be queried (CHUNKSIZE)
Object name start with	- query object names starting with (ONAME)
Library name starts with	- query library names starting with (LNAME)
Size of sample	- Size of same

A random sample of SIDMPL segments will be returned. A spooled file will be produced that contains only the segment addresses. Full details will be placed in member (the name of the directory dump name) in file DDSMP in the library specified for the directory dump.
