2.0 Updating the Identity Manager Components on Linux

The following considerations apply before you update Identity Manager components on Linux platforms:

Ensure that you install the zip and unzip RPM packages.

NOTE:NetIQ recommends that you obtain the dependent packages from your operating system subscription service to ensure continued support from your operating system vendor. If you do not have a subscription service, you can find the recent packages from a website such as http://rpmfind.net/linux.
(Conditional) If you are updating the Identity Manager from 4.8 to 4.8.5 directly, then you must apply the Identity Applications 4.8.0.1 patch before 4.8.5 version in the following scenarios:
- eDirectory 9.2 and Identity Applications 4.8 are installed on the same server.
- iManager 3.2 and Identity Applications 4.8 are installed on the same server.
- Identity Applications 4.8 and PostgreSQL are installed on the same server.
The Identity Applications 4.8.0.1 patch resolves the dependencies between the NGINX module and the OpenSSL libraries. For instructions on applying the patch, see the NetIQ Identity Applications 4.8.0 Hotfix 1 Release Notes.

If you do not apply the Identity Applications 4.8.0.1 patch, the Identity Vault update fails and the installer reports the following error message:
```
Problem: patterns-edirectory-9.2.2-6.x86_64 requires netiq-openssl = 1.0.2u, but this requirement cannot be provided not installable providers: netiq-openssl-1.0.2u-32.x86_64[edirectory-9.2.2] 
Solution 1: deinstallation of netiq-nginx-1.14.2-1.x86_64 
Solution 2: do not install patterns-edirectory-9.2.2-6.x86_64 
Solution 3: break patterns-edirectory-9.2.2-6.x86_64 by ignoring some of its dependencies
```
(Conditional) Before installing or upgrading Identity Manager to 4.8.5 version on a server running Red Hat Enterprise Linux (RHEL) operating system, make sure that the ua_configure.sh and rpt_configure.sh scripts in the Identity_Manager_4.8_Linux.iso are replaced with the latest scripts available at TID KM000007635. If you do not replace the scripts, the PostgreSQL database configuration may fail with the following error:

NOTE:This issue occurs when the PostgreSQL database is installed on either Identity Applications or Identity Reporting on the same server.
```
symbol lookup error: /opt/netiq/idm/postgres/bin/../lib/libgssapi_krb5.so.2: undefined symbol: krb5_ser_context_init, version krb5_3_MIT
```
