PROBLEM WITH PG COMMAND UNDER AIX

ITEM: RTA000028791

QUESTION:                                                                       
Customer is running AIX 3.2.3 and is unable to get the pg command               
to work.  The message is "pg: cannot create temp file".  There is               
plenty of space in /tmp (8mb) and the permissions on the /tmp                   
directory are "rwxrwxrwt".  They are able to use the more command               
with no problem.  Any ideas on what's going on here?                            
                                                                                
---------- ---------- ---------- --------- ---------- ----------                
A: The pg command needs the /usr/tmp directory to create the temp file.         
   Furthermore, on 3.2 systems, /usr/tmp is a symbolic link to /var/tmp.        
                                                                                
   If you do not have that directory and link setup, the pg command will        
   not be able to create a temp file.  Note that the link is not vital          
   for creating the temp file, but the temp file should be made in              
   /var/tmp, instead of /usr/tmp.  The following commands will ensure          
   that you have the proper setup: (You must be root to do this)                
                                                                                
   mkdir /var/tmp               # Creates the /var/tmp directory, where         
                                # the temp file will reside (after the          
                                # link.                                         
   ln -s /var/tmp /usr/tmp      # Creates the symbolic link.                    
   chmod 1777 /var/tmp          # Changes the permissions of /var/tmp to        
                                # be drwxrwxrwt                                 
                                                                                
   If you still get the errors after executing the above commands, then         
   you might not have enough space left in /var to create the temp file.        
   You can use the "df" command to determine if you need to extend the          
   /var filesystem.                                                             
                                                                                
   Temp files are only necessary for when you pipe input into the pg           
   command. For example, the commands: "pg file" and "cat file | pg"            
   accomplish exactly the same thing, but the second one needs a temp           
   file whereas the first one does not.                                         
                                                                                
   Note that the "more" and "vi" commands do not use a temp file -- they        
   use a buffer in memory instead.
