OID 11g Attempting To Clean Up Old/Invalid Process Entries, Oidmon Start Fails With: exec(): 0509-036 Cannot load program oidmon <etc> (Doc ID 1057063.1)

Last updated on SEPTEMBER 09, 2019

Applies to:

Oracle Internet Directory - Version and later
Information in this document applies to any platform.


Oracle Internet Directory (OID) 11g R1 ( or 11gR1 Patchset1 (

Due to previous failed installations/re-installations, OID was reinstalled one last time reconfigured for new ports using a new componentname called oid2, and everything had been working properly, including OID replication.

However, process entries for an old componentname oid1 is still referenced in the ods.ods_process_status table, from the previous installs/reinstalls.&nbsp; Also, unwanted / incorrect statuses for oid1 processes are still getting displayed from opmnctl and oidctl status commands.

In order to clean up / remove these references of leftover / invalid / unwanted oid1 component process entries, everything has been shutdown with opmnctl stopall, and all processes have been verified to be down with ps -ef | grep oid&nbsp; and ps -ef | grep odi.&nbsp; Next, needs to attempted to run just oidmon and oidctl by themselves to cleanly remove the unwanted refences, as per &lt;Document 889673.1&gt;.

Issue #1
Startup of oidmon fails with:

oidmon connect=oiddb start

exec(): 0509-036 Cannot load program oidmon because of the following errors:
rtld: 0712-001 Symbol nzcsf_oid_read was referenced from module oidmon(), but a runtime definition of the symbol was not found.
rtld: 0712-001 Symbol nzcsfCLS_CloseLdapStore was referenced from module oidmon(), but a runtime definition of the symbol was not found.
&lt;etc, etc&gt;

This being a 64 bit platform, the following was also tried, but the same error continued:
- Removing /lib from the $LD_LIBRARY_PATH environment variable.
- unset the $LD_LIBRARY_PATH variable.

After changing /lib to /lib32 on the $LD_LIBRARY_PATH, the error then changed to:

exec(): 0509-036 Cannot load program &lt;path/oidmon&gt; because of the following errors:
0509-022 Cannot load module &lt;path/lib&gt;
0509-150 Dependent module &lt;path/lib&gt; could not be loaded.
0509-103 The module has an invalid magic number.

Continued trying different settings for the lib path variable, but oidmon start either returned the same above error or hung.

Issue #2
After applying the Solution #1 (see below), a subsequent oidctl stop command (to remove the invalid references to componentname oid1 on the table) succeeded, but the table still showed the invalid/unwanted row(s).
