Installation Instructions

Obtaining MIB files

Installing this Fix Pack  removes existing MIB files. This Fix Pack does not contain the Management Information Base (MIB files). The MIBs are required for network discovery.

If you are upgrading from 4.2 Fix Pack 5 or earlier, complete the following steps to obtain the MIB files.

1.  Locate a zip file named com.ibm.tivoli.netcool.ncp.mibs.all.any_*.zip within the IBM Installation Manager shared location that contains the MIB files from the previous Fix Pack installation. The exact path might be different in your installation. An example path is: /opt/IBM/IBMIM/native/
2. Unzip this file.
3. Load the MIBs into the database by running the ncp_mib command, as described in Loading updated MIB information: https://www.ibm.com/docs/en/networkmanager/4.2.0?topic=systems-loading-updated-mib-information

If you are installing this Fix Pack without upgrading, or you are unable to locate the MIB files using the above procedure, complete the following steps to obtain the MIB files.

1. Run the ncp_mib command, as described in Loading updated MIB information: https://www.ibm.com/docs/en/networkmanager/4.2.0?topic=systems-loading-updated-mib-information
2. If you have Network Manager 4.2 Fix Pack 5 or 6 installed, back up the contents of the $NCHOME/precision/mibs/ directory to a backup directory outside $NCHOME. For example, /mibs_backup/.
3. If you have an earlier version than 4.2 Fix Pack 5 installed, complete the following steps:
3.1. Back up the contents of the $NCHOME/precision/mibs/ directory to a backup directory outside $NCHOME. For example, /old_mibs/. Keep this directory and its files in case you want to roll back to this version later.
3.2 Download the Network Manager Fix Pack 5 (4.2.0.5) files from IBM Fix Central:  https://www.ibm.com/support/fixcentral/ . Important: You must download the Linux x86 files, regardless of which platform you are using.
3.2. Expand the Network Manager package into a temporary directory.
3.3. Expand the repositories/disk1/ad/native/file000876 archive file into a backup directory outside $NCHOME, for example, /mibs_backup/. This directory now contains the default MIB files.
3.4. If you customized or added any MIB files, copy the customized or new MIB files from  /old_mibs/ over the default files in /mibs_backup/.
4. Regardless of the version of Network Manager you installed, the /mibs_backup/ directory now contains the most current set of MIB files from Fix Pack 5, plus any additions and customizations.
