10. 10 lcg-info

11. 11 lcg-info We can use this command to list which CE and SE satisfies a set of given conditions. We can also show values of a set of given attributes. Information is taken from BDII especified in LCG_GFAL_INFOSYS variable. Request sintax is: attr1 op1 valueN,... attrN opN valueN

17. 17 R-GMA

18. 18 To start R-GMA command line type: >rgma On begin this message appears. R-GMA – Command line (1)

19. 19 Command history is managed with “up” and “down” keys. For quick access to a command type it’s first characters and press “CTRL-R” Use TAB key to complete the command input. Command input

20. 20 help Shows general help help Show specific help exit or quit Quit RGMA command line. Show tables Show all table names of the schema. (Schema) Describe Show table structure information. General commands

21. 21 To obtain data use SQL SELECT clause: rgma> SELECT * FROM GlueService SELECT behaviour is according to the request type. There are three request types of SELECT: LATEST. Return most recents rows for each primary key. HISTORY. Return all historic rows for each primaty key. CONTINUOUS Return rows as soon are being inserter. Querying data (1)

22. 22 To change request type use SET QUERY : rgma> SET QUERY LATEST or rgma> SET QUERY CONTINUOUS To show current request type: rgma> SHOW QUERY Querying data (2)

23. 23 1.Show all schema tables: rgma>show tables 2.Show information about GlueSite table: rgma>describe GlueSite 3. Make a query about GlueSite table: rgma>set query latest rgma>show query rgma>select Name,Latitude,Longitude from GlueSite Exercises

24. 24 Rows max age can be configured. To limit latest or history rows age use SET MAXAGE rgma> SET MAXAGE 2 minutes rgma> SET MAXAGE 120 To show row max age: rgma> SHOW MAXAGE To unable max age: rgma> SET MAXAGE none Row max age

25. 25 Another property of requests is “timeout”  We can use timeout to prevent network failure or other situations  In continuous type, timeout means how long the request will continue returning new rows.  Default timeout it’s 1 minute. rgma>SET TIMEOUT 3 minutes or rgma>SET TIMEOUT 180 To show current timeout rgma>SHOW TIMEOUT Timeout property

26. 26 We can use SQL INSERT to add new data: rgma>INSERT INTO userTable VALUES (’a’, ’b’, ’c’, ’d’) Producer component inserts data on R-GMA. This component manages INSERT clause. Data production and insertion (1)

27. 27 To show the current producer type: rgma>show producer To set the producer type: rgma>set producer latest Data production and insertion (2)

28. 28 1.Insert and select one row using a contiuous producer to support Continuous and historic querys. rgma>set producer continuous rgma>insert into userTable values('cod','string',1.4,66) rgma>set query continuous rgma>set maxage 1 minutes rgma>set timeout 5 seconds rgma>select * from userTable Exercise

29. 29 To set the secondary producer for consume from userTable table: rgma>SECONDARYPRODUCER userTable Secondary producer can be set for latest or history request. rgma>SET SECONDARYPRODUCER latest To show current secondary producer type: rgma>SHOW SECONDARYPRODUCER Secondary producer

30. 30 Insert and select data using a secondary producer supporting latest querys. rgma>set secondaryproducer latest rgma>secondaryproducer userTable rgma>show producers of userTable rgma>set producer continuous rgma>insert into userTable values ('cod','string',5.2,44) rgma>set query latest rgma>select * from userTable Exercise
