Good day, list,
We use olsnodes in oraenv to set the ORACLE_SID. I have seen other
implementations of setting the ORACLE_SID in oraenv, but I am asking
specifically about olsnodes and how it works. Looking at the readable,
non-binary olsnodes, I see that it calls olsnodes.bin. I am not very
versatile with debuggers or decompilers, but I do see the documentation has
a brief synopsis for syntax. Nothing about the syntax suggests that I would
be generating a log file each time we use olsnnodes, nor that olsnodes would
be scanning the entire $CRSHOME/log/$node/client directory each time it is
run. We have observed that olsnodes has become slower and slower, and
finally noticed that this directory has 65,000 files in it. Is there
supposed to be a job to clean those up? Why are there at all, and why is
olsnodes scanning the directory? The only reason I found this directory was
doing an strace (linux) on olsnodes and seeing an entry like the following
for each file:
access("/u01/app/oracle/product/crs/log/urbdb1/client/css551.log", F_OK) = 0
getcwd("/u01/app/oracle/local/bin", 4096) = 26
chdir("/u01/app/oracle/product/crs/log/db1/client") = 0
getcwd("/u01/app/oracle/product/crs/log/urbdb1/client", 4096) = 46
chdir("/u01/app/oracle/local/bin") = 0
mmap(NULL, 143360, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x2a97790000
munmap(0x2a97790000, 143360) = 0
