16 Oracle Linux Manager XML/RPC API
If you are an advanced user, you can use Oracle Linux Manager XML/RPC API to create web interfaces and
scripts to perform or automate tasks. More information about the API is available at
https://olmsvr_FQDN/rpc/api
on an
Oracle Linux Manager server.
For example, the following get-channel-summaries Python script uses the API to obtain a list of channels, the numbers of packages in each channel, and the number of systems that are subscribed to each channel:
#!/usr/bin/python # # get-channel-summaries [--server URL <url>] [--username <user>] [--password <passwd>] import getopt, struct, sys, xmlrpclib from array import * # Insert default values for Oracle Linux Manager server API URL, # Oracle Linux Manager admin user name, and Oracle Linux Manager admin password url = "https://olmsvr.mydom.com/rpc/api" username = "swadmin" password = "swadmin" usage1 = "Usage: get-channel-summaries [--serverUrl <url>] \\\n" usage2 = " [--username <user>] [--password <passwd>]" try: opts,args = getopt.getopt(sys.argv[1:],"s:u:p:",["serverUrl=","username=","password="]) except getopt.GetoptError as err: print(usage1+usage2) sys.exit(1) for o,a in opts: if o in ("-s", "--serverUrl"): url = a elif o in ("-u", "--username"): username = a elif o in ("-p", "--password"): password = a else: assert False, "Unknown option" # Connect to Oracle Linux Manager client = xmlrpclib.Server(url,verbose=0) session = client.auth.login(username,password) # Get channel list channels = client.channel.listAllChannels(session) # Build channel arrays indexed by channel ID channel_label = {} channel_packages = {} channel_systems = {} for channel in channels: channel_label[channel['id']] = channel['label'] channel_packages[channel['id']] = channel['packages'] channel_systems[channel['id']] = channel['systems'] # Print output header fmt1 = '{0:<40s}{1:<10s}{2:<10s}' print fmt1.format('Channel label','Packages','Systems') print fmt1.format('-------------','--------','-------') # Print channel label, package count, and system count -- sorted by label fmt2 = '{0:<40s}{1:<10d}{2:<10d}' for key,value in sorted(channel_label.iteritems(),key=lambda(k,v): (v,k)): id = int(key) print fmt2.format(value,channel_packages[id],channel_systems[id]) # Disconnect from Oracle Linux Manager client.auth.logout(session)
The following is sample output from running this script:
Channel label Packages Systems ------------- -------- ------- base-channel 0 0 epel6-channel-label 68 0 epel6-channel1-label 3 0 epel6-channel2-label 1 0 ol5-i386-channel-label 44 0 ol5-i386-test-label 34 0 ol5-x64-channel-label 44 0 ol6-i386-channel-label 45 0 ol6-x64-channel-label 45 1 ol7-channel-label 45 1 oraclelinux6-x86_64 0 0 oraclelinux6-x86_64-addons 0 0 oraclelinux6-x86_64-spacewalk22-client 0 0 oraclelinux6-x86_64-spacewalk22-server 0 0 oraclelinux6-x86_64-spacewalk24-client 0 0 oraclelinux6-x86_64-spacewalk24-server 0 0 oraclelinux6-x86_64-spacewalk26-client 0 0 oraclelinux6-x86_64-spacewalk26-server 0 0 oraclelinux6-x86_64-spacewalk27-server 0 0 uln-channel-label 173 0
The following example shows the get-reposync-list script, which displays the schedules for synchronizing repositories.
#!/usr/bin/python # # get-reposync-list [--serverUrl <url>] [--username <user>] [--password <passwd>] import getopt, struct, sys, xmlrpclib from array import * # Insert default values for Oracle Linux Manager server API URL, # Oracle Linux Manager admin user name, and Oracle Linux Manager admin password url = "https://olmsvr.mydom.com/rpc/api" username = "swadmin" password = "swadmin" usage1 = "Usage: get-reposync-list [--serverUrl <url>] \\\n" usage2 = " [--username <user>] [--password <passwd>]" try: opts,args = getopt.getopt(sys.argv[1:],"s:u:p:",["serverUrl=","username=","password="]) except getopt.GetoptError as err: print(usage1+usage2) sys.exit(1) for o,a in opts: if o in ("-s", "--serverUrl"): url = a elif o in ("-u", "--username"): username = a elif o in ("-p", "--password"): password = a else: assert False, "Unknown option" # Connect to Oracle Linux Manager client = xmlrpclib.Server(url,verbose=0) session = client.auth.login(username,password) # Get channel list channels = client.channel.listAllChannels(session) # Build channel name array indexed by channel ID channel_label = {} channel_schedule = {} for channel in channels: id = int(channel['id']) channel_label[id] = channel['label'] channel_schedule[id] = '' # Get repository synchronization list schedules = client.taskomatic.org.listActiveSchedulesByBunch(session,'repo-sync-bunch') # Construct schedule array indexed by channel ID for schedule in schedules: channel_schedule[int(schedule['data_map']['channel_id'])] = schedule['cron_expr'] # Print output header fmt = '{0:<40s}{1:<40s}' print fmt.format('Channel label','Schedule') print fmt.format('-------------','--------') # Print channel labels and repository synchronization schedule (if defined) for key,value in sorted(channel_label.iteritems(),key=lambda(k,v):(v,k)): id = int(key) sched = channel_schedule[id] if (len(sched) > 0): print fmt.format(value,sched) else: print fmt.format(value,"Sync not scheduled") # Disconnect from Oracle Linux Manager client.auth.logout(session)
The following example shows what the output of this command might look like:
Channel label Schedule ------------- -------- oraclelinux6-x86_64 0 30 0 ? * * oraclelinux6-x86_64-addons 0 30 2 ? * * oraclelinux6-x86_64-mysql 0 30 4 ? * * oraclelinux6-x86_64-playground 0 30 3 ? * * oraclelinux6-x86_64-spacewalk24-client 0 0 5 ? * * oraclelinux6-x86_64-spacewalk24-server 0 30 5 ? * * oraclelinux6-x86_64-spacewalk26-client 0 0 2 ? * * oraclelinux6-x86_64-spacewalk26-server 0 0 3 ? * * oraclelinux6-x86_64-spacewalk27-server 0 0 4 ? * * oraclelinux6-x86_64-uek 0 0 5 ? * * oraclelinux6-x86_64-uek-r3 0 30 1 ? * * ...
