 howDB2 has a lot files under /proc on aix Hi, All, We have DB2 ESE V8.2 on aix5l box. I found on the aix box, DB2 has a lot files under /proc. You can see from the following: dr-xr-xr-x 1 db2inst5 db2admin 0 Mar 17 13:44 1015810 dr-xr-xr-x 1 db2inst3 db2admin 0 Mar 17 13:44 1011954 dr-xr-xr-x 1 db2inst3 db2admin 0 Mar 17 13:44 1007660 dr-xr-xr-x 1 db2inst5 db2admin 0 Mar 17 13:44 1003684 dr-xr-xr-x 1 root system 0 Mar 17 13:44 1 dr-xr-xr-x 1 root system 0 Mar 17 13:44 0 /proc # What are those files for? As a DBA, I have any ideal on those files. Thanks, George 03/17      |

Hi, Thank you for the reply. It seams those files are related O.S instead of database management system. |

If you go into those directories, you can check up on a lot of what they're doing with the various pseudo-files therein. For example, if AIX is like Linux, /proc/$$/fd can be informative as to what that process has opened (it's a directory of symlinks). You should check up more with the AIX 5L documentation (the L stands for the Linux compatibility layer). This has nothing to do with DB2. Thus, it's the sysadmin's job, not the DBA's job. Of course, if you're also the sysadmin, well, then you should look it up :-) |

Yes. Such a (virtual) file/directory exists under /proc for each process. -- Knut Stolze DB2 z/OS Utilities Development IBM Germany |
