Published Response Targets
SQL Server Support Services
In short: SQL Server support is agreed incident response and proactive monitoring by JusDB DBAs — covering outages, blocking and deadlocks, AG failover triage, routine maintenance, security, and the BI stack (SSIS/SSRS/SSAS) across SQL Server 2016–2022 and Azure SQL. Initial-response targets are 2 to 4 hours during covered business hours, Mon–Fri 09:00–18:00 IST (UTC+5:30). Where your service agreement includes 24x7 on-call, the initial-response target for P1 incidents is 30 minutes. Targets are not resolution guarantees.
We cover production emergencies and proactive maintenance, on-premises or in the cloud (Azure SQL, Amazon RDS for SQL Server, and EC2).
JusDB provides Microsoft SQL Server production support under a service agreement. JusDB Database Reliability Engineers resolve Always On synchronization failures, deadlock storms, TempDB allocation stalls, and corruption emergencies.
Vendor support failing you — sound familiar?
- ▸ Microsoft Premier support callback queue — P1 ticket open for 8 hours; you are in a callback queue and the engineer who eventually calls has to start the diagnostic from scratch.
- ▸ Always-On AG incident outside business hours — Primary stepped down at 2am, listener routing broke, the on-call SRE does not have
sys.dm_hadrqueries memorised — restoration took 90 minutes for what should have been 10. - ▸ Licensing-edge incident with no clean path — Upgrade to Enterprise Edition would resolve this but Procurement needs 4 weeks; meanwhile you are working around the Standard limit with risky workarounds.

What Our SQL Server Support Covers
End-to-end SQL Server support from emergency response to proactive health management.
Incident Response
Rapid diagnosis and resolution of SQL Server outages, blocking storms, disk emergencies, and service crashes.
Proactive Monitoring
Continuous automated monitoring of AG health, backup jobs, disk space, blocking, CPU, memory, and SQL Server error logs.
Routine Maintenance
Scheduled index maintenance, DBCC CHECKDB, statistics updates, log space management, and patch assessment.
Performance Emergencies
Emergency query tuning, blocking resolution, plan cache clearing, and TempDB pressure relief.
Security Monitoring
Login audit review, permission drift detection, failed login alerting, and SQL injection pattern monitoring.
Capacity Planning
Disk growth trend analysis, memory and CPU capacity reports, and proactive scaling recommendations.

How JusDB Support compares to alternative models.
Generic cloud ticketing and standard IT helpdesks triage SQL Server outages with reboot scripts and multi-hour queues. Here is how our dedicated DBRE coverage compares:
| Evaluation Vector | JusDB DBRE Support | In-House DBA | Legacy Agency | Developer Generalist |
|---|---|---|---|---|
| Incident Response Targets & Escalation | Direct paging to named DBREs for Sev-1 incidents, with no L1 ticket filtering. Initial-response targets: 2 to 4 hours in covered business hours; 30 minutes for P1 incidents with 24x7 on-call. Targets, not resolution guarantees. | Best-effort response contingent on individual sleep schedules, PTO gaps, and absence of secondary on-call rotation. | 2–4 hour response time routed through generic level-1 helpdesk dispatchers before reaching a database administrator. | Best-effort triage by developers pulled from active sprint work without defined SLA commitments or emergency escalation trees. |
| Always On & Engine Technical Depth | Deep engine mastery: Always On AG lease timeouts, split-brain mitigation, synchronous redo queue tuning, and TempDB latch contention resolution. | Standard administration skills, but often lacks specialized internals knowledge for complex multi-subnet AG failover or distributed transactions. | Basic SQL Agent maintenance and restart scripts; escalates complex cluster synchronization and corrupt page issues back to customer. | Reliance on SSMS GUI wizards; struggles with sys.dm_os_wait_stats, extended events, and deep HADR diagnostics. |
| Emergency War Room Collaboration | Live bridge or Slack war-room participation with application teams, driving live diagnostic queries and real-time mitigation. | Isolated troubleshooting with limited visibility into application stack or microservice connection pooling patterns. | Asynchronous communication strictly via web portal tickets, requiring cumbersome log dumps before taking action. | Frantic ad-hoc debugging in team chat without structured incident command or database telemetry tooling. |
| Proactive Root Cause Analysis (RCA) | A postmortem on the timeline set in your service agreement, with deadlock graph forensics, Query Store plan regressions, and recommended DDL and index remediations. | Brief retrospective notes often deprioritized due to ongoing backlog of developer support requests. | Cursory ticket resolution note ("instance restarted, service restored") without deep root-cause forensics or preventative safeguards. | No formal RCA; recurring incidents masked by automated server reboots or ad-hoc query patches. |
| Diagnostic Telemetry & Tooling | Extended Events profiling, continuous DMV monitoring, custom wait-statistic baselines, and automated latch contention detectors. | Basic SQL Server Profiler traces (risking production overhead) or default PerfMon counters with limited historical retention. | Generic OS-level CPU and disk alerts without SQL Server catalog, buffer pool, or plan cache introspection. | Reliance on third-party APM traces with zero visibility into internal lock escalation, spinlocks, or TempDB PFS/GAM allocation bottlenecks. |
| Security Hardening & Compliance | Zero-trust ephemeral access, CIS SQL Server benchmark hardening, Transparent Data Encryption (TDE) audits, and SOC 2 / ISO 27001 alignment. | Broad sysadmin permissions granted to multiple internal staff, with infrequent credential rotations or audit log reviews. | Shared admin passwords accessed across rotating offshore shifts without immutable session recording. | Unrestricted sa account or db_owner credentials embedded directly in application configuration files. |
Critical SQL Server Incidents We Triage
Production SQL Server outages require rapid, low-level engine diagnostics when deadlocks cascade into application connection pool exhaustion, transaction logs fill disks, or storage subsystems trigger page corruption errors:
Catastrophic Deadlock Storm Freezing Critical Transactions
Mutually blocking transactions on clustered index keys or unindexed foreign keys trigger continuous deadlock victim terminations (1205 errors), cascading into application thread pool exhaustion and systemic timeouts.
JusDB immediately analyzes the system_health Extended Events ring buffer, extracts deadlock graphs, optimizes transaction isolation levels (RCSI), and injects covering indexes to eliminate key lookup locks.
Transaction Log Exhaustion Freezing Database Writes (9002 Error)
Runaway uncommitted transactions, stuck replication/AG log truncation (AVAILABILITY_GROUP or LOG_BACKUP log_reuse_wait), or autogrowth caps exhaust disk space, immediately throwing fatal error 9002.
Rapidly triage sys.databases.log_reuse_wait_desc, isolate open transactions via DBCC OPENTRAN, trigger emergency log backups, and clear AG replication queues to restore transactional writes safely.
Corrupted Database Pages Triggering 823/824 I/O Errors
Underlying storage subsystem degradation, torn writes, or bad disk sectors cause page checksum failures, leading to fatal 823/824 errors and rendering tables or indexes inaccessible.
Isolate corrupted allocation units using DBCC CHECKDB, execute non-destructive single-page restores (RESTORE DATABASE ... PAGE) from verified transaction log backups without taking the entire database offline.
Our on-call DBREs execute non-blocking emergency diagnostics to isolate transaction log exhaustion and deadlock graphs in seconds:
Audits transaction log file space allocation, current log size in megabytes, and the specific log reuse wait reason preventing truncation.
-- 1. SQL Server: Transaction Log Reuse Wait & Space Audit SELECT name, log_reuse_wait_desc, total_size_mb = (size * 8) / 1024 FROM sys.databases;
Extracts recent XML deadlock reports directly from the ring buffer and default system_health session files without profiler overhead.
-- 2. SQL Server: Deadlock Graph Extraction from Extended Events
SELECT CAST(event_data AS XML) AS DeadlockGraph FROM sys.fn_xe_file_target_read_file('system_health*.xel', null, null, null) WHERE object_name = 'xml_deadlock_report';SQL Server Support FAQs
