U00020554 Data sequence couldn't be written into a file. Agent HOSTG.*** isn't active at the moment

[Legacy User]

We've had a user where their task was failing with U00020554 Data sequence couldn't be written into a file. Agent 'HOSTG.xxxx' isn't active at the moment even though the HostGroup is active, and they have access to this.

The object was using a HostGroup in the WRITE_PROCESS, and WRITE_PROCESS does not support HostGroup.

example:

:SET &RET# = WRITE_PROCESS(&HND#,"C:\temp\export.txt",HOSTG.HOSTS,@AUTOMIC_LOGINS,OVERWRITE)

where HOSTG.HOSTS is a host group.

Some workaround you can apply:

a) Use a Host

:SET &RET# = WRITE_PROCESS(&HND#,"C:\temp\export.txt",WIN01,@AUTOMIC_LOGINS,OVERWRITE)

b)  Use a VARA that holds a list of hosts, then retrieve it using a key (key can be client, client+system_name, etc)

In the example below, the client number is the key.

:set &client# = &$client# 

:set &client# = format(&client#) 

:print client is &client# 

:SET &HOSTVALUE# = get_var(VARA.HOSTS,&client#) 

:SET &HND# = PREP_PROCESS_FILENAME("VWASWV11U02_OS_01","C:\automic\v112u\automationengine\bin\*.exe",,,,"COL=DELIMITER","DELIMITER=*\*","UC_LOGIN=@AUTOMIC_LOGINS") 

:SET &RET# = WRITE_PROCESS(&HND#,"C:\temp\export.txt",&HOSTVALUE#,@AUTOMIC_LOGINS,OVERWRITE)

c)
Why not using an PREP_PROCESS_AGENTGROUP instead?

This will provide an Agent without the need of using a VARA that has to be updated manually.

Silly example but clearly :-)

:SET &HND# = PREP_PROCESS_AGENTGROUP("HOSTG.WIN.LOADBALANCE","*WIN*",BY_RULE)
:PROCESS &HND#
:   SET &AGENT# = GET_PROCESS_LINE(&HND#,1)
:   SET &STATUS# = GET_PROCESS_LINE(&HND#,2)
:   PRINT "Agent chosen: &AGENT# -- Status: &STATUS#"
:ENDPROCESS
:SET &RET# = WRITE_PROCESS(&HND#,"C:\temp\write_proc.txt",&AGENT#,"@LOGIN.DEFAULT",OVERWRITE)
:print  &RET#
:CLOSE_PROCESS &HND#

PREP_PROCESS_AGENTGROUP is another option.
However, we've decided to go with VARA since the VARA will have a list of all their agents for Prod and non-Prod, primary and backup agents. The host will be determined/pulled based on the key (client+system name+B/P). This way they can promote their process from non-Prod to Production without having to change anything in non-Prod or Prod environment.
