Getting SQL0444N with Reason code: "6" ? For example, when you do a query like: db2 "select count(*) from SYSIBMADM.DB_HISTORY" You can get the following error. SQL0444N Routine "*IST_HIST" (specific name "ADMIN_LIST_HIST") is implemented with code in library or path "...e/db2adminListHist", function "adminListHistTrusted" which cannot be accessed. Reason code: "6". SQLSTATE=42724 Why is that? How to troubleshoot? 1.... [More]
Hello DBAs Recently came across this question about dropping members that reside in the same physical server. Consider the db2instance -list output like this. #db2instance -list ID TYPE STATE HOME_HOST CURRENT_HOST ALERT PARTITION_NUMBER LOGICAL_PORT ETNAME -- ---- ----- --------- ------------ ----- ---------------- ------------ ------ 0 MEMBER STARTED host1 host1 NO 0 1 host1-en1.xxxx.com 1 MEMBER STARTED host1 host1 NO 0 0 host1-en1.xxxx.com 2 MEMBER STARTED host2 host2 NO 0 0 host2-en1.xxxx.com 3 MEMBER STARTED host2 host2 NO 0 1...

During crash recovery, if many load operations have to be replayed, then it might take a long time to complete. The load operation will keep the pending operations in transaction logs no matter if it is recoverable load or non-recoverable. These pending operations will be kept in transaction log just before the table status is changed back from "load in progress" state to "normal" state. If the crash recovery starting point - min(lowtranlsn, minbufflsn) is before load pending operations then db2 will have to replay... [More]

As guardians of data we are constantly faced with the challenge of moving data from one platform to another for a multitude of reasons. We faced such challenge at one of my favorite client location where most databases were being migrated to reside on private cloud environment. A standard procedure in order migrate a few hundred database instance into a Linux cloud farm was built.... [More]
We are pleased to share a new video available on the IBM Electronic Support YouTube Channel: Keeping Service Requests to a Single Issue Did you know that when you limit a Service Request to a single issue, IBM Support is better able to prioritize and update you on the issue's status? If you have more than one issue, you are welcome to open multiple requests (even for topics related to a single larger issue, such as an upgrade). By signing in to Service Request, you will be able to see all of your open requests... [More]
When using DB2 HADR the local service/port (HADR_LOCAL_SVC) and remote service/port (HADR_REMOTE_SVC) are defined. But, why netstat output shows that hadr is using other port numbers too ? Both HADR_LOCAL_SVC and HADR_REMOTE_SVC are used as the lower level TCP server listener port numbers only. The client side of the TCP uses free ports available from OS from that side. HADR uses TCP server and TCP client at the lower level. In this context, one HADR db side listens on its hadr_local_svc port as TCP server, the... [More]
Issue: NullPointerException was thrown when one of our customers tried to load latest DB2 JCC driver (db2jcc.jar - V10.1 and above) using a custom class loader ( like open source module NestedJarClassLoader). The same worked while loading old DB2 V8.2 db2jcc.jar driver (2.11.24). Here is the error stack: Caused by: java.lang.NullPointerException at com.ibm.db2.jcc.am.md.run(md.java:49) at java.security.AccessController.doPrivileged(Native Method)... [More]
As of now, DB2 on Windows supports ActivestatePerl (both 32bit and 64 bit) and Strawberry Perl (32 bit ONLY). To get the 32 bit DBD::DB2 binaries supported with 32 bit Strawberry Perl, you must email email@example.com or contact IBM support for the required binaries. 64 bit Strawberry Perl is not supported yet. Thanks!

Consider the following scenario, in a DB2 HADR configuration using ASYNC mode. Presently,the log files were extracted from TSM to a local file system on the standby server. Standby database was deactivated and re-activated causing the standby to go into LocalCatchUp state. However, its unable to read the local log file because its considered as a "stale" file and the standby re-enters a RemoteCatchUp state. This process was repeated two to three times and the standby fails to read the log file and switch HADR to RemoteCatchUp... [More]

One scenario you may have !! You attend a monthly DB operation meeting. Each DB administrator team from Oracle, DB2 and Sybase presents monthly events and various monitoring results. On first turn, an Oracle guy indicates a performance issue on a specific day and says an SQL has triggered the issue. And.......he shows the historical performance data for the SQL by keeping on track of the change day by day. Actually the hash key value ' SQL_ID ' of Oracle enables this kind of analysis. ... [More]
