RE: FNDSTRPDM memory enhancement

[craigs@xxxxxxxxx]

Thanks for the response John.  I just looked at Hawkeye software.  I
couldn't find how much this costs.  I don't think we probably find strings
often enough to justify the cost in purchasing software.  I copied the
thread to the midrange list awhile ago where it probably should have been
in the first place.  It started a discussion on storage pools, main memory,
and SETOBJACC.  My FNDSTR is probably running okay for now.  Someone
mentioned maybe using RSE in WDSC to search instead but I am still nervous
about anything running searches in mass that I am unsure about.

Thanks,
Craig Strong

 Just a quick question?  Have you looked into a product from Hawkeye called     
                 
 Pathfinder?  It might give you all the functionality that you are describing   
                 
 here plus a whole lot more.

 I have a command I created called FNSTR that searches for a string in any      
                 
 source file in any or all libraries in batch.  It has the same options as      
                 
 FNDSTRPDM so it is basically a beefed up version of FNDSTRPDM.  As many of     
                 
 you have probably noticed, doing a FNDSTRPDM (or 25 then F13) on members       
                 
 goes a little slow the first time.  It is slowest when interactive as it is    
                 
 displaying the scan progress.  The second time around on the same command      
                 
 on the same set of members goes fast.  My guess it that these members are      
                 
 saved in memory since any user doing scans on that set of members goes         
                 
 fast.  If you open each member in an RPG program, do a single read, and        
                 
 close, I think that places the entire member in memory.  Doing a test on       
                 
 this (open, 1 read, close) of each member in a source file in a library and    
                 
 then doing a "25" F13 in that source file showed it being very quick.  Just    
                 
 doing an open and close without a read did not speed up the process.           
                 
 Every morning a system scan is initiated in batch that basically does a        
                 
 DSPFD for all common source physical files to outfiles.  I was thinking of     
                 
 taking these resulting outfiles and submitting jobs to batch for each          
                 
 library processed for each source file.  Then, whenever someone does any       
                 
 type of find, it would be quick.  I think members would open faster too.       
                 
 We also have a utility called FNDSRC that uses these outfiles to scan for      
                 
 any library containing the input member and source file name.  This utility    
                 
 wouldn't be effected but it comes in very handy.                               
                 
 Should I do the open, 1 read, close of every source member in batch jobs (1    
                 
 library per job)?  Any system issues that might come up in doing this?         
                 
 Am I correct in thinking of this as members stored in memory?  Is this the     
                 
 same thing as when a program is replaced while someone is using it and they    
                 
 are running the version still stored in memory until they exit?                
                 
 Am I crazy?                                                                    
                 
                                                                                
                 
 Thanks,
