Special Guest: Melanie Stopfer, DB2 Brain Surgeon, IBM Software Group
db2pd Party! The Power of db2pd!99% of our audience learned something! Who knew that there were so many options for the powerful and popular "db2pd" command? Not only did Melanie share dozens of db2pd command examples and tips, but she also compared and contrasted to various MON_GET function calls and SQL commands. Bonus! Melanie also talked about DB2 security, trusted contexts, HADR, locking, indexes, and more! Enjoy... |
Show Host Scott Hayes Commentary
I will repeat from Episode #138 on Upgrading to DB2 10.5 Best Practices: Everyone in the DB2 for LUW community knows, or should know, Melanie Stopfer. I took DB2 Common Server classes from her back in 1992, then DB2 UDB (V5) upgrade classes, then DB2 LUW classes at every IBM and IDUG conference. Melanie has a warm, wonderful, and impactful way of teaching, and I think it'd be fair to say that SHE is one of the top three IBM people in the world that have most impacted DB2 LUW's success. She loves chocolate chip cookies too!
Here's just a few things you are going to learn about: db2pd -help, db2pd -mempools, db2pd -alldbs, -repeat N second, db2pd -applications, db2pd -tablespaces, using db2pd in DPF environments, db2pd -dbpartitionnum N, db2pd -logs, db2_all, rah command, db2pd security requirements, db2pd -edus, db2pd -db DBNAME -dbcfg, enhancements to db2pd in V10.5 FP4 Cancun, db2look -d DBNAME -printdbcfg, db2look -d DBNAME -createdb, admin_get_storage_paths, db2pd -db DBNAME -storagegroups, SYSCAT.TABLESPACES, mon_get_tablespaces, mon_tbsp_utilization, db2pd -db DBNAME -tablespaces, db2 luw temporary table compression with db2pd -temptable, mon_get_index, db2pd -db DBNAME -tcbstats index, SYSPROC.ADMIN_GET_MEM_USAGE, db2mtrk, mon_get_memory_set, mon_get_memory_pool, SYSIBMADM.MON_BP_UTILIZATION, mon_get_bufferpool, db2pd -db DBNAME -bufferpools, SYSIBMADM.MON_PKG_CACHE_SUMMARY, mon_get_pkg_cache_stmt, db2pd -db DBNAME -dynamic, Scan Sharing - monitoring this innovative technique with db2pd -db DBNAME -scansharing, db2pd -db DBNAME -locks, mon_get_workload, SYSIBMADM.MON_LOCKWAITS, db2pd -db DBNAME -wlock, mon_format_lock_name, db2pd -db DBNAME -transactions, load query, list utilities, db2pd -utilities, db2pd -db DBNAME -reorg, db2pd -reorgs index -db DBNAME, db2 trusted contexts, db2pd -db DBNAME -appl, db2pd -db DBNAME -logs, mon_get_transaction_log, lock isolation levels including the new currently committed (as of v9.7), db2pd -workclasssets -alldbs, db2pd -thresholds -alldbs, db2pd -db DBNAME -hadr, tuning DB2_HADR_BUF_SIZE, and more!
For all of the wonders and valuable information you can obtain from db2pd, remember that the data presented is only accumulated since the last db2start command or database activation. There is no history. There are no trends. There are no click-through integrations with other tools or diagnostic functionality. db2pd accesses DB2's memory directly without requiring a database connection, so sometimes it will work when other monitoring functions won't. SQL to MON_GET functions also access memory directly with very nominal overhead, but do require a database connection. If you want to know percentages or ratios, with db2pd you'll mostly likely need to do math as it merely dumps data.
A message from our sponsor:
DBI Software
Don't fast forward through today's educational commercial from DBI! Melanie talked about "db2pd -db DBNAME -tcbstats index" and index scans. Listen to the commercial to learn what this really means. DBI also demonstrated Lock Contention Analysis wherein you can see which connections are blocking other connections - functionality much more robust than db2pd with integrated option to terminate connections!
