NetWorker: NMC restore (recoverpsm) fails on a Linux server due to missing libraries

NetWorker Management Console (NMC) database restore (recoverpsm) fails with the following error on a Linux server:

root@nmcserver:/opt/lgtonmc/bin# ./recoverpsm
ld.so.1: recoverpsm: fatal: libdbodbc12_r.so: open failed: No such file or directory
Killed

In this example, the library link for libdbodbc12_r.so is broken or missing. 

The same type of failure can occur if another library is unlinked.

The steps in this KB assume that the NMC has been installed under the default Linux/UNIX location: /opt/lgtonmc. If you have installed the NMC under a different location, make the necessary changes to all commands shown in this KB for your environment.

1. List the dynamic dependencies used by the recoverpsm binary: 

ldd /opt/lgtonmc/bin/recoverpsm

root@nmcserver:/opt/lgtonmc/bin# ldd /opt/lgtonmc/bin/recoverpsm
        libdl.so.1 =>    /lib/64/libdl.so.1
        libdbodbc12_r.so =>      (file not found)
        libdbtasks12_r.so =>     (file not found)
        libsocket.so.1 =>        /lib/64/libsocket.so.1
        libnsl.so.1 =>   /lib/64/libnsl.so.1
        libresolv.so.2 =>        /lib/64/libresolv.so.2
        libpthread.so.1 =>       /lib/64/libpthread.so.1
        libthread.so.1 =>        /lib/64/libthread.so.1
        librt.so.1 =>    /lib/64/librt.so.1
        libCstd.so.1 =>  /usr/lib/64/libCstd.so.1
        libCrun.so.1 =>  /usr/lib/64/libCrun.so.1
        libm.so.2 =>     /lib/64/libm.so.2
        libc.so.1 =>     /lib/64/libc.so.1
        libmp.so.2 =>    /lib/64/libmp.so.2
        libmd.so.1 =>    /lib/64/libmd.so.1
        libcryptoutil.so.1 =>    /lib/64/libcryptoutil.so.1

2. You can confirm the library location with the Linux/UNIX find command: 

find / -name libdbodbc12_r.so

root@nmcserver:/opt/lgtonmc/bin# find / -name libdbodbc12_r.so
/opt/lgtonmc/sybasa/lib/libdbodbc12_r.so

3. Link the library with the Linux/UNIX export command: 

export LD_LIBRARY_PATH=/opt/LGTOnmc/sybasa/lib/:/opt/LGTOnmc/bin/recoverpsm

4. Now ldd should report the library location for libdbodbc12_r.so: 

ldd /opt/lgtonmc/bin/recoverpsm

root@nmcserver:/opt/LGTOnmc/bin# ldd /opt/LGTOnmc/bin/recoverpsm
        libdl.so.1 =>    /lib/64/libdl.so.1
        libdbodbc12_r.so =>      /opt/LGTOnmc/sybasa/lib//libdbodbc12_r.so
        libdbtasks12_r.so =>     /opt/LGTOnmc/sybasa/lib//libdbtasks12_r.so
        libsocket.so.1 =>        /lib/64/libsocket.so.1
        libnsl.so.1 =>   /lib/64/libnsl.so.1
        libresolv.so.2 =>        /lib/64/libresolv.so.2
        libpthread.so.1 =>       /lib/64/libpthread.so.1
        libthread.so.1 =>        /lib/64/libthread.so.1
        librt.so.1 =>    /lib/64/librt.so.1
        libCstd.so.1 =>  /usr/lib/64/libCstd.so.1
        libCrun.so.1 =>  /usr/lib/64/libCrun.so.1
        libm.so.2 =>     /lib/64/libm.so.2
        libc.so.1 =>     /lib/64/libc.so.1
        libw.so.1 =>     /lib/64/libw.so.1

5. Attempt to restore the NMC database:

6. Start the GST service:

systemctl start gst
ps -ef | grep gst

root@nmcserver:/opt/lgtonmc/bin# systemctl start gst

root@nmcserver:/opt/lgtonmc/bin# ps -ef | grep gst
    root  1895  1793   0 14:31:40 pts/1       0:00 grep gst
    root  1893  1888   0 14:23:37 ?           0:00 /opt/lgtonmc/bin/gstsnmptrapd -d -Le -f -C -c /opt/lgtonmc/etc/snmptrapd.conf
    root  1888     1   0 14:23:14 ?           0:01 /opt/lgtonmc/bin/gstd
