centos robot

[Jose Romero]

Hello.

Dear community, I am trying to install a ca uim robot on a centos but I get the following errors.

[root@PrimaryServer LINUX_23_64]# ./nimldr

-bash: ./nimldr: cannot execute binary file: Exec format error

[root@PrimaryServer LINUX_23_64]# file nimldr

nimldr: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.4.1, with debug_info, not stripped

 

[ossadm@PrimaryServer ~]$ uname -a

Linux PrimaryServer 4.19.36-vhulk1907.1.0.h794.eulerosv2r8.aarch64 #1 SMP Fri Jul 3 11:05:33 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux

Could you tell me which libraries are the right ones for this?

Hi Jose,

Looks like you have an old nimldr. Try downloading the latest from your PHub. Here is what I show for the latest:

Thank you for your prompt reply, I will try that

you know which are the libraries that are needed to install the robot in centos

[Gregg Stillwell]

Not sure if listed anywhere.

You can always use ldd command on UIMHOME/robot/controller and spooler on a installed system. Only found these KB's

Hi @Jose Romero,


based on your file nimldr output, you're trying to use an x86_64 Linux (ELF) binary and based on your uname command output, the system is running EulerOS on an ARM-compatible platform.
According to https://techdocs.broadcom.com/us/en/ca-enterprise-software/it-operations-management/unified-infrastructure-management/20-3/installing/product-compatibility/ca-uim-compatibility-matrix.html there is existing UIM robot support for the following architectures:
PowerPC
Itanium
x86_32 (Intel compatible)
x86_64 (Intel compatible)
SPARC64
While I would expect and appreciate native ARM support, it seems like UIM robots for ARM are not yet existing.
There might be some workarounds using QEMU/binfmt or other techniques, but these will probably be hard to get running and maintain.
You might consider using remote monitoring (rsp, etc.).

good luck,
Raphael

[Jose Romero]

Thanks for your prompt reply
a question with the rsp probe can I monitor linux log and processes?​​​

[Raphael Franck]

Hi @Jose Romero,

I recommend checking out the documentation:
https://techdocs.broadcom.com/us/en/ca-enterprise-software/it-operations-management/ca-unified-infrastructure-management-probes/GA/alphabetical-probe-articles/rsp-remote-system-probe.html
Also, it's always a good idea to do some tests in a lab environment on your own.

regards,
Raphael

Please try to use the logmon and process probes from remote shared folders/ssh commands.
